Incidence Of All-cause Mortality Research Articles

Negative association of C-reactive protein-albumin-lymphocyte index (CALLY index) with all-cause and cause-specific mortality in patients with cancer: results from NHANES 1999–2018

BackgroundThe CALLY index, which is derived from C-reactive protein (CRP) content, serum albumin level, and total lymphocyte count, reflects the immune, nutritional, and inflammatory status of the body. Lack of sufficient evidence on the correlation between the CALLY index and the prognosis of cancer patients with various cancer forms. This study seeks to elucidate the association between the CALLY index and mortality from all causes as well as specific causes in cancer patients within a U.S. population.MethodsThis investigation encompassed 3511 cancer-afflicted adults from the National Health and Nutritional Examination Surveys (NHANES) spanning 1999 to 2018. The CALLY index was measured at baseline only. The relationship between the CALLY index and mortality from both all causes and cancer specifically was examined using Cox proportional hazards models. Additionally, restricted cubic spline, piecewise linear regression, and various subgroup and sensitivity analyses were employed.ResultsOver a median follow-up of 103 months, 1,355 deaths occurred, and the incidence of all-cause mortality for these participants was 38.34%. Our findings indicate that an elevated CALLY index correlates with a diminished risk of all-cause mortality. Upon applying a natural logarithmic transformation to the CALLY index, the comprehensively adjusted model revealed that each one-unit increment in ln CALLY corresponded to a 18% decrease in all-cause mortality risk among cancer patients (HR = 0.82, 95% CI:0.79–0.86). Analyses of mortality due to cardiac and cancer-related causes yielded consistent results, which were robust across various subgroup and sensitivity analyses.ConclusionThe CALLY index demonstrated a linear and negative association with all-cause mortality, as well as mortality caused by cancer and cardiac conditions, highlighting its significant prognostic value in patients with oncological conditions.

Vitamin D and Cardiovascular Outcomes in Multiple Sclerosis

Background: Vitamin D (25(OH)D) deficiency is linked to increased cardiovascular disease (CVD) risk in the general population, but its implications for people with multiple sclerosis (pwMS) remain unexplored. This study aimed to evaluate the association of 25(OH)D with long-term CVD outcomes in pwMS and the impact of vitamin D supplementation. Methods: This observational cohort study analysed anonymised medical records from 70 healthcare organisations following pwMS for 5-years (2019-2024). PwMS and deficient or inadequate 25(OH)D levels were 1:1 propensity-score matched with pwMS and adequate 25(OH)D levels, for demographics, comorbidities, and cardiovascular care. Cox proportional hazard models analysed the incidence of all-cause mortality, stroke, acute myocardial infarction, heart failure, angina, atrial fibrillation/flutter, and a composite measure of major adverse cardiovascular events (MACE). Propensity-matched pwMS who had deficient or inadequate 25(OH)D levels taking cholecalciferol were compared to pwMS and adequate 25(OH)D levels (not taking supplementation). Results: Amongst 74,372 pwMS, 9% had deficient 25(OH)D levels, 18% inadequate, and 73% adequate. Deficient, or inadequate 25(OH)D levels were associated with an increased rate of MACE (HR, 1.32 [95%CI: 1.19, 1.46], HR, 1.29 [95%CI: 1.20, 1.40], respectively) compared to those with adequate levels. Cholecalciferol supplementation in pwMS and deficient or inadequate 25(OH)D levels did not alleviate the higher CVD rate (HR, 1.39 [95%CI: 1.21,1.60], HR, 1.31 [95%CI: 1.17, 1.47], respectively) in comparison to those with adequate 25(OH)D levels taking no vitamin D supplementation. Conclusions: Deficient or inadequate 25(OH)D levels in pwMS were associated with an increased rate of MACE, which may not be mitigated by vitamin D supplementation.

Exercise-induced Reduction in Left Ventricular Ejection Fraction in the Absence of Coronary Artery Disease: Clinical Characteristics and Outcomes

During exercise stress echocardiography (ESE) there are patients with normal left ventricular ejection fraction (LVEF) who paradoxically develop reduced LVEF during exercise despite absence of coronary artery disease (CAD) and a significant hypertensive response. This study sought to describe the clinical features and outcomes of this population. Among ESE performed between 2003 and 2022, patients without CAD by angiogram within 90 days of ESE, resting LVEF ≥50% with a ≥5% LVEF decrease during ESE were included. Outcomes assessed were all-cause mortality, heart failure (HF) hospitalization, and atrial fibrillation (AF). Kaplan-Meier and Cox regression methods were used to analyze time-to-event outcomes. Among 213,643 ESE, 134 patients met eligibility criteria. The mean age of the population was 66±10 years, 76% were women, and 16% had AF at baseline. Mean LVEF was 58±4% at rest and 43±4% at peak stress. Stress ECG met criteria for ischemia in 14% of these patients. The 10-year estimated incidence of HF hospitalization was 17.6% (95% CI 9.0-26.2). Among the subgroup without AF at baseline, the 10-year estimated incidence of developing AF was 23.4% (95% CI 13.4-33.4). The 10-year estimated incidence of all-cause mortality was 12.9% (95% CI 5.5-20.3), with 89% of deaths occurring due to non-cardiovascular causes. Patients with exercise-induced reduction in LVEF in the absence of obstructive CAD have a high incidence of HF hospitalizations and AF. The underlying pathophysiology of this disease process needs to be further investigated.

Prosthesis selection for reconstruction of superior vena cava: comparison of midterm patency rates.

This study compared the mid-term patency of expanded polytetrafluoroethylene grafts without rings versus that of bovine pericardial conduits used for superior vena cava reconstruction for various thoracic diseases. Among 80 patients who underwent superior vena cava resection and reconstruction between 2009 and 2023 at our institution, 31 patients who received polytetrafluoroethylene grafts without rings(Polytetrafluoroethylene group) and 28 patients who received bovine pericardial conduits(Bovine group) were enrolled. Median follow-up durations were 19.5 and 64.6 months in Polytetrafluoroethylene and Bovine groups, respectively. Primary outcome was midterm graft patency rate, and secondary outcomes were early and midterm clinical outcomes including all-cause mortality and superior vena cava reintervention. Operative mortality was 1.7%. Cumulative incidence of all-cause mortality was not significantly difference between the groups. Graft occlusion was detected in 22 patients. Cumulative incidence of graft occlusion was 24.2%, 36.4%, 42.4%, 48.5%, and 60.6% at 1 month, 3 months, 6 months, 1 year, and 2 years, respectively, in Bovine group, whereas no graft occlusion was observed in Polytetrafluoroethylene group(P=0.007). Although the incidence of graft occlusion was higher in Bovine group, cumulative incidence of reintervention was not significantly different between the groups(0.0% vs. 3.0% in Polytetrafluoroethylene vs. Bovine groups at 1 year, P=0.406). Multivariate analysis demonstrated that bovine pericardial conduit(Polytetrafluoroethylene graft as reference) and left brachiocephalic vein reconstruction(right brachiocephalic vein reconstruction as reference) were significant risk factors for graft occlusion. In superior vena cava reconstruction, polytetrafluoroethylene grafts without rings were superior to bovine pericardial conduits in terms of midterm graft patency.

Preventive effects of nitric oxide donors in contrast-induced nephropathy in patients undergoing coronary artery angiography: an updated systematic review and meta-analysis of 13 randomized controlled trials.

Contrast-induced nephropathy (CIN) is associated with increased mortality and morbidity in patients undergoing coronary angiography (CAG) and percutaneous coronary intervention (PCI). We aimed to assess the latest evidence on the preventive effects of nitric oxide (NO) donors in CIN patients undergoing CAG/PCI. We conducted a comprehensive systematic review and meta-analysis of RCTs from PubMed, Web of Science, Scopus, Embase, and Cochrane searches until May 5th, 2024. Dichotomous data were pooled using risk ratio (RR), and continuous data were pooled using mean difference (MD), both with a 95% confidence interval (CI), using (R version 4.3). Our analysis included 13 RCTs encompassing 3,550 patients. NO donors were significantly associated with a decreased incidence of CIN compared to placebo either as an oral administration (RR: 0.33 with 95% CI [0.26, 0.42], P < 0.01) or IV infusions (RR: 0.56 with 95% CI [0.40, 0.78], P < 0.01). Moreover, NO donors were significantly associated with decreased serum creatinine levels compared to placebo either as an oral administration (MD: - 0.07 with 95% CI [- 0.10, - 0.04], P < 0.01) or IV infusions (MD: - 0.07 with 95% CI [- 0.09, - 0.04], P < 0.01). In terms of safety, NO donors were significantly associated with a decreased incidence of major adverse cardiac events (MACE) compared to placebo as an oral administration (RR: 0.64 with 95% CI [0.45, 0.89], P < 0.01). However, there was no significant difference between NO donors as IV infusions and placebo in MACE (RR: 0.68 with 95% CI [0.38, 1.21], P = 0.18). Finally, NO donors were significantly associated with a decreased incidence of all-cause mortality compared to placebo as an oral administration (RR: 0.58 with 95% CI [0.36, 0.94], P = 0.03). Nevertheless, there was no statistically significant difference in all-cause mortality between IV infusions of NO donors and placebo (RR: 1.84 with 95% CI [0.40, 8.52], P = 0.44). NO donors as adjunct therapy are associated with reduced incidence of CIN and decreased serum creatinine levels, either as an oral or IV administration. They were also associated with reduced incidence of MACE, all-cause mortality, and recurrent myocardial infarction as an oral administration, which makes this simple, low-cost intervention an important therapeutic option in patients undergoing CAG/PCI.

Abstract 4124370: DAPT for 1-Month Followed by P2Y12 Inhibitor Monotherapy Versus DAPT for 12-Months After Percutaneous Coronary Intervention: A Systematic Review and Meta Analysis of Randomized Controlled Trials

Background: Dual antiplatelet therapy (DAPT) is well established as standard of care following percutaneous coronary intervention (PCI). Recent trials have shown a potential benefit in the reduction of hemorrhagic events with a shorter course of DAPT. However, the optimal duration of DAPT following PCI remains unclear. Question: Is 1 month of DAPT followed by P2Y12 inhibitor monotherapy superior to the standard 12-month DAPT regimen in terms of cardiovascular outcomes in patients post-PCI? Methods: Medline, PubMed, and Cochrane Central Register of Controlled Trials databases were searched for randomized clinical trials (RCTs) comparing 1-month vs. 12-months of DAPT followed by P2Y12 inhibitor monotherapy post-PCI. The outcomes of interest were cardiovascular death, myocardial infarction, and major bleeding. We used R version 4.1.2 (The R Foundation, 2021) to pool the data using a random-effects model. Heterogeneity was assessed with I2. Results: We included three RCTs reporting data from 22,413 patients, of whom 11,180 (49.8%) were treated with 1-month of DAPT, followed by P2Y12 inhibitor monotherapy. Follow-up ranged from 12 months to 24 months. The incidence of all-cause death (RR 1.20; 95% CI 0.95-1.51; p=0.12) and myocardial infarction (RR 0.86; 95% CI 0.71-1.05; p=0.14) were not significantly different between the groups. However, major bleeding (RR 0.51; 95% CI 0.26-0.99; p=0.048) was significantly reduced with a short course of DAPT followed by P2Y12 inhibitor monotherapy, as compared with standard 12 months of DAPT. Conclusion: Following PCI, a transition from DAPT to P2Y12 inhibitor monotherapy at 1-month is associated with a significant reduction in major bleeding as compared with standard DAPT for 12-months, with no significant change in the incidence of all-cause mortality or myocardial infarction.

The association between stress hyperglycemia ratio and clinical outcomes in patients with sepsis-associated acute kidney injury: a secondary analysis of the MIMIC-IV database

BackgroundThe stress hyperglycemia ratio (SHR) is associated with poor outcomes in critically ill patients. However, the relationship between SHR and mortality in patients with sepsis-associated acute kidney injury (SA-AKI) remains unclear.MethodsThe data of patients with SA-AKI, identified based on the KDIGO criteria, were retrospectively collected from the Beth Israel Deaconess Medical Center between 2008 and 2019. SHR was calculated as follows: (glycemia [mmol/L]) / (1.59 × HbA1c [%] – 2.59). Primary outcomes were 30-day and 1-year mortality. The cumulative incidence of all-cause mortality was assessed using Kaplan–Meier survival analysis. Multivariable-adjusted logistic and Cox models and restricted cubic spline curves were used to analyze the correlation between SHR and all-cause mortality. Post-hoc subgroup analysis was performed to compare the effects of SHR across different subgroups.Results1161 patients with SA-AKI were identified and categorized into four SHR quartiles as follows: Q1 (0.26, 0.90), Q2 (0.91, 1.08), Q3 (1.09, 1.30), and Q4 (1.31, 5.42). The median age of patients was 69 years, with 42.7% of the patients being women and 20.2% of the patients having chronic kidney disease. The 30-day and 1-year mortality were 22.1% and 35.0% respectively. Kaplan–Meier survival analysis indicated a gradual decrease in survival probability with increasing SHR quartiles. An increased SHR exhibited a strong correlation with 30-day mortality (hazard ratio [HR], 1.50; 95% confidence interval [CI], 1.18–1.90; P < 0.001) and 1-year mortality (HR, 1.32; 95% CI, 1.06–1.65; P = 0.014). SHR has a nonlinear relationship with 1-year mortality but not with 30-day mortality (P-nonlinear = 0.048 and 0.114, respectively). The results of subgroup analysis were mostly consistent with these findings.ConclusionAn increased SHR is independently associated with 30-day and 1-year mortality in patients with SA-AKI. Therefore, SHR may serve as an effective tool for risk stratification in patients with SA-AKI.

Clinical Impact of Baseline Frailty Status and Residual Mitral Regurgitation After Transcatheter Edge-to-Edge Repair: Insights From the OCEAN-Mitral Registry.

The Clinical Frailty Scale (CFS) is a useful frailty marker for predicting clinical outcomes in patients undergoing invasive therapy. However, the clinical impact of CFS after transcatheter edge-to-edge repair in patients with mitral regurgitation (MR) remains unclear. This study aimed to elucidate the association between the baseline frail status defined by the CFS and clinical outcomes with or without postprocedural MR ≥2+ (post-MR ≥2+) after transcatheter edge-to-edge repair. Based on a Japanese multicenter registry (OCEAN [Optimized Catheter Valvular Intervention]-Mitral), data from 2078 patients with MR who underwent transcatheter edge-to-edge repair were analyzed. The patients were classified into 5 groups: CFS 1 to 3, 4, 5, 6, and ≥7. The procedural and clinical outcomes and post-MR ≥2+ were compared among the groups. All-cause mortality for up to 2 years was explored using Cox proportional hazards regression analysis. Although the rates of acute procedural success and post-MR ≥2+ were similar, all-cause mortality at 2 years was significantly increased across the 5 CFS categories (15.5%, 23.8%, 27.7%, 34.6%, and 48.8%, respectively, P<0.001). The incremental CFS categories and post-MR ≥2+ were independent predictive risk factors of all-cause mortality (all P<0.05). Among the patients with 5 CFS categories, the incidence of all-cause mortality was higher in those with post-MR ≥2+ than in those without (all P<0.05). Although prognosis was poor in patients with higher CFS grade after transcatheter edge-to-edge repair, minimizing modifiable factors of residual MR is warranted to improve the clinical outcomes.

Early left ventricular unloading during extracorporeal membrane oxygenation in cardiogenic shock: A systematic review and meta-analysis.

Left ventricular (LV) unloading is a crucial intervention to decrease the harmful consequences of extracorporeal membrane oxygenation (ECMO) on hemodynamic status in cardiogenic shock (CS) patients. However, a lingering question preoccupies experts: Should we intervene early or wait until clinical deterioration caused by increasing afterload is detected? A systematic review and meta-analysis synthesizing studies, which were retrieved by systematically searching PubMed, Web of Science, SCOPUS, and Cochrane through December 2023. We used R V. 4.3 to pool dichotomous data using risk ratio (RR) and continuous data using mean difference (MD) with a 95% confidence interval (CI). CRD42024501643. Eight studies with 2.117 patients were included. Early/prophylactic LV unloading was associated with a lower incidence of all-cause mortality [RR: 0.87 with 95% CI (0.79, 0.95), p < 0.01]. However, there was no significant difference between the two groups regarding cardiac mortality [RR: 1.01 with 95% CI (0.68, 1.48), p = 0.98], non-cardiac mortality [RR: 0.86 with 95% CI (0.46, 1.62), p = 0.64], and in-hospital mortality [RR: 0.95 with 95% CI (0.86, 1.05), p = 0.30]. There was no significant difference between the two groups regarding ECMO weaning, myocardial recovery, ECMO duration, and length of hospitalization. Early/prophylactic LV unloading during ECMO for CS patients was associated with a decreased incidence of all-cause mortality and sepsis or infection, with no effect on ECMO weaning, myocardial recovery, ECMO duration, and hospital length of stay.

Neutrophil-to-lymphocyte ratio predicts poor prognosis in patients with chronic kidney disease-related pulmonary hypertension: A retrospective study.

Inflammation plays a crucial role in chronic kidney disease (CKD) and pulmonary hypertension (PH). Considering that the neutrophil-to-lymphocyte ratio (NLR) has recently emerged as a powerful predictor of adverse outcomes in many chronic diseases, we aimed to investigate the association between NLR and all-cause mortality in patients with CKD-related PH. A total of 176 hospitalized patients with predialysis CKD-related PH were recruited retrospectively from January 2012 to June 2020 by reviewing electronic medical records. The NLR and clinical characteristics of the patients were included in the current analysis. The Kaplan-Meier method and univariate and multivariate Cox regression analyses were performed to identify the association between NLR and the incidence of all-cause mortality. Baseline NLR values were associated with hemoglobin, estimated glomerular filtration rate and C-reactive protein. During a median follow-up period of 32.5 (11.3-53.0) months, 23 patients died. Regardless of whether the NLR acted as a continuous variable with a hazard ratio of 1.408 (95% confidence interval: 1.124-1.763) or a categorical variable (NLR ≤4.3 vs NLR >4.3) with a hazard ratio of 3.100 (95% confidence interval: 1.299-7.402), an elevated NLR was significantly associated with all-cause mortality in different models. A greater NLR at baseline was remarkably associated with a higher all-cause mortality in hospitalized patients with CKD-related PH.

Temporal trends in mortality and hospitalisation risk in patients with heart failure according to frailty status

Abstract Background Heart failure (HF) and frailty often coexist, and patients with both conditions have a higher risk of mortality and hospitalisation compared with those who are not frail. Over the past two decades, advances in medication targeting HF have been introduced, prolonging the life of patients with HF, but also resulting in increased comorbidity accumulation and susceptibility to frailty. It remains unknown how the interplay between HF and frailty at HF onset impacts patient prognosis and how this has changed over time. Purpose We investigated the temporal trends in the risk of all-cause mortality and HF hospitalisation in patients with HF from 1999 to 2017 according to their frailty status. Methods From Danish nationwide registers, we included patients with new-onset HF. Patients were categorised into four groups according to the year of HF onset: 1999-2002, 2003-2007, 2008-2012, and 2013-2017. The Hospital Frailty Risk Score was used to classify patients into frailty severity categories: 1) non-frail, 2) moderately frail, and 3) severely frail. The primary outcome was the 5-year cumulative incidence of all-cause mortality, assessed using the Kaplan-Meier estimator. The secondary outcome was the 5-year risk of HF hospitalisation, assessed using the Aalen-Johansen estimator, accounting for the competing risk of death. Moreover, a sensitivity analysis was conducted using a multivariable Cox proportional hazard model, investigating the interaction between year group and frailty status for all-cause mortality, comparing frail patients with non-frail patients. Results Among 131,235 patients with HF (median age 74 years; 39.7% female), 102,635 (78%) were categorised as non-frail, 26,054 (20%) as moderately frail, and 2609 (2%) as severely frail. The proportion of moderately frail patients increased the most, from 13% in 1999 to 25% in 2017. From 1999-2002 to 2003-2017, the 5-year cumulative incidence of all-cause mortality declined from 56.4% (95% CI, 55.8-57.0%) to 33.3% (32.6-34.1%), 79.8% (78.5-81.0%) to 58.6% (57.2-60.1%), and 90.8% (85.6-96.0%) to 79.8% (76.4-83.2%) in the non-frail, moderately frail, and severely frail patient group, respectively (Fig 1). The largest relative improvement was observed in the non-frail patient group. The 5-year cumulative incidence of HF hospitalisation remained fairly constant across the frailty groups (Fig 2). Conclusions From 1999 to 2017, we observed an increase in moderately and severely frail patients. Overall, the mortality risk decreased across all frailty groups. These findings underscore the importance of implementing guidelines directed at frail patients with HF.5-year risk of all-cause mortality5-year risk of HF hospitalisation

High ABCD2-score after transient ischemic attack is associated with a two-fold higher stroke-rate during long-term follow-up

Abstract Background The ABCD2-score is a validated risk score used to estimate the short-term risk of stroke after transient ischemic attack (TIA). However, "real-world" contemporary data on the long-term risk of stroke after TIA according to ABCD2-score are needed in order to guide preventive strategies. Purpose To determine the long-term risk of stroke after TIA according to modified ABCD2-score (high-risk (≥4 points) versus low-risk (&amp;lt;4 points)). Methods Patients aged ≥18 years with first-time TIA were included from the Danish Stroke Registry (2014-2020). The study population was stratified in high-risk (≥4 points) and low-risk (&amp;lt;4 points) ABCD2-score group. We utilized a modified ABCD2-score consisting of the following parameters: age ≥60 years, hypertension, clinical features, and diabetes. The 3-year risk of ischemic stroke and all-cause mortality was compared between the high-risk and low-risk group using the Aalen-Johansen and Kaplan-Meier estimator. A cox regression model was also conducted. Results In total, 21,433 patients with first-time TIA were included; 1,281 (6.0%) in the high-risk and 20,152 (94.0%) in the low-risk group. Patients in the high-risk group were older (77.5 years [interquartile range [IQR] 70.8-84.1] versus 70.3 years [IQR 60.1-78.2]), more often females (52.2% versus 46.6%) (p &amp;lt;0.001), more comorbid and received more medication compared with the low-risk group at baseline. The 3-year cumulative incidence of stroke was 6.0% [95% CI: 4.6-7.5] in the high-risk group and 4.2% [95% CI: 3.9-4.5] in the low-risk group, and the unadjusted hazard ratio (HR) was 1.6 (95% CI 1.2 – 2.0) (Figure 1). The cumulative incidence of all-cause mortality within three-years after TIA was 28.9% [95% CI: 26.1-31.7] in the high-risk group and 10.3% [95% CI: 9.9-10.8] in the low-risk group. The unadjusted HR was 3.2 (95% CI 2.8 – 3.6). Conclusions Patients with high-risk ABCD2-scores had an almost two-fold higher associated long-term stroke-rate compared to those with low-risk scores. Trials focusing on preventive measures, including evidence-based antithrombotic strategies, especially for the high-risk group are warranted.

Rotational atherectomy versus orbital atherectomy for the treatment of calcified coronary lesions: a systematic review and meta-analysis of 81,873 patients

Abstract Background Previous studies have suggested that pre-treatment of coronary artery calcification with rotational atherectomy (RA) prior to stent deployment can enhance procedural success, but this does not necessarily translate into improved clinical outcomes. Recently, the Orbital Atherectomy (OA) system has been introduced into clinical practice to enhance lesion preparation. Purpose Our study aims to evaluate the safety and efficacy of both RA and OA as pre-treatment strategies before stent deployment in patients with coronary artery calcification. Methods We conducted a comprehensive systematic review and meta-analysis of randomized controlled trials (RCTs) and observational studies. These were identified through systematic PubMed, Web of Science, Scopus, Embase, and Cochrane searches until January 2024. Dichotomous data were pooled using risk ratio (RR), and continuous data were pooled using mean difference (MD), both with a 95% confidence interval (CI), using Stata version 17. Results Our analysis included eleven studies encompassing 81,873 patients. No significant difference was observed between RA and OA in terms of major adverse cardiovascular events (MACE) (RR: 0.81 with 95% CI [0.64, 1.02], P= 0.07). However, OA was significantly associated with a decreased incidence of all-cause mortality (RR: 0.60 with 95% CI [0.52, 0.70], P&amp;lt; 0.01), target vessel revascularization (TVR) (RR: 0.43 with 95% CI [0.22, 0.82], P= 0.01), coronary artery bypass grafting (CABG) (RR: 0.78 with 95% CI [0.62, 0.97], P= 0.03), and fluoroscopy time (MD: -3.93 with 95% CI [-7.39, -0.48], P= 0.03). There was no significant difference between RA and OA in cardiac death (RR: 2.65 with 95% CI [0.94, 7.51], P= 0.07), target lesion revascularization (TLR) (RR: 0.57 with 95% CI [0.23, 1.41], P= 0.22), myocardial infarction (RR: 0.79 with 95% CI [0.62, 1.01], P= 0.06), stent thrombosis (RR: 0.33 with 95% CI [0.09, 1.23], P= 0.10), stroke (RR: 0.76 with 95% CI [0.57, 1.01], P= 0.06), re-admission (RR: 0.76 with 95% CI [0.48, 1.19], P= 0.23), vessel closure (RR: 0.78 with 95% CI [0.18, 3.33], P= 0.74), procedural duration (MD: -5.43 with 95% CI [-21.71, 10.84], P= 0.51), length of hospital stay (MD: 0.21 with 95% CI [-0.47, 0.90], P= 0.54), and contrast amount (MD: -3.68 with 95% CI [-9.37, 2.01], P= 0.21). Conclusion Both RA and OA as pre-treatment strategies before stent deployment demonstrate similar outcomes for numerous cardiovascular events. However, OA is associated with lower rates of all-cause mortality, TVR, CABG, and fluoroscopy time.

Prognosticating short-term outcomes in STE-ACS patients with intra-procedure slow flow/no-reflow: an analysis of predictive factors in primary percutaneous coronary revascularization

Abstract Background "ST-segment elevation myocardial infarction (STEMI)" is the most lethal form of "ischemic heart disease (IHD).primary "percutaneous coronary intervention (PCI)" as the first-line treatment for STEMI patients, as it offers better outcomes compared to other medical or surgical options [1,2]. One major concern in interventional cardiology is the occurrence of "slow flow/no-reflow (SF/NR)", which refers to the poor myocardial perfusion to the infarct-related artery as a result of microvascular obstruction. Objectives In this study, we compared the incidence of short-term outcomes between two groups of patients based on the occurrence of intra-procedure "slow flow/no-reflow (SF/NR)" and identified predictors of short-term outcomes. Method This study enrolled a series of consecutive patients who underwent primary "percutaneous coronary intervention (PCI)" for "ST-elevation myocardial infarction (STEMI)". The patients who developed SF/NR during the procedure were compared with their counterparts for the incidence of short-term "major adverse cardiovascular events (MACE)". Furthermore, the study aimed to identify predictors of short-term mortality in these patients. Result In this study, a total of 2,582 patients were included. Among them, 79.1% (2,042) were male. The average age of the patients was 55.7 ± 11.2 years. Intra-procedure SF/NR was observed in 21.7% (560) of the patients. During median short-term follow-up of 180 [144-205] days, patients with SF/NR exhibited higher incidence of all-cause mortality (23.6% vs. 12.3%; p&amp;lt;0.001), and MACE (30.4% vs. 16.9%; p&amp;lt;0.001) with hazard ratio of 1.82 [1.46-2.27; p&amp;lt;0.001] and 1.69 [1.39-2.05; p&amp;lt;0.001], respectively. Among patients with SF/NR, adjusted odds ratio for total ischemic time: 1.04 [1.00-1.07; p=0.041], random blood sugar levels: 1.01 [1.00-1.01; p&amp;lt;0.001], intubation status: 2.79 [1.26-6.18; p=0.011], post-procedure sub-optimal flow: 1.76 [1.04-2.98; p=0.034], and intra-procedural arrhythmias: 5.48 [2.03-14.79; p&amp;lt;0.001] were found to be independent predictors of short-term mortality. Conclusion In conclusion, the presence of intra-procedure SF/NR carries significant prognostic implications. Patients with intra-procedure SF/NR face a significantly higher risk of short-term adverse outcomes.

Heart failure and renal outcomes in patient treated with GLP1 agonists

Abstract Introduction Glucagon-like peptide-1 receptor (GLP1) agonists are emerging as a primordial treatment for diabetes and to reduce cardiovascular burden, both of them factors that play an important role in the developing of renal chronic disease and heart failure, and vice versa. The debut of renal chronic disease and the manifestation of acute renal injury/failure can lead to the discontinuation of treatment, which in patients suffering from heart failure who tend to be polymedicated could end up in lessening their survival. Methods A metanalysis of randomized clinical trials (RCT) comparing GLP1 agonists with placebo was performed. The endpoint of the study was to analyze all-cause mortality, hospitalization or urgent medical visit for heart failure, a kidney outcome composite, which is slightly heterogenic depending on the RCT, and the manifestation of acute renal injury/failure as an adverse effect or that lead to the discontinuation of treatment. The meta-analysis was performed using the inverse variance method, using the fixed effects model when there was no heterogeneity and the random effects model when heterogeneity is significant. Results A sum of 9 randomized controlled trial were included where a GLP1 agonists such as albiglutide, dulaglutide, exenatide, liraglutide, lixinatide or semaglutide compared with placebo. 77684 patients were incorporated, while 39497 were treated with a GLP1 agonists. The mean age was of 63.7 years (SD ± 1.97 years), 60080 (77.3%) suffered from diabetes, 60552 (77.9%) from cardiovascular disease and 14367 from chronic heart failure (18.4%). The mean eGFR was 77.3 mL/min (SD ± 3.3 mL/min). As showed in the forest plots, treatment with GLP1 agonists reduced all-cause mortality by 12% (RR: 0.88, 95% CI 0.83-0.92; p&amp;lt;0.001), hospitalization or urgent medical visit for heart failure by 10% (RR: 0.90, 95% CI 0.83-0.98; p&amp;lt;0.001), the kidney composite outcome by 22% (RR: 0.78, 95% CI 0.70-0.87; p&amp;lt;0.001), while it showed no statistical reduction in acute renal injury/failure (RR: 0.89, 95% CI 0.79-1.01; p=0.069). Conclusion Treatment with a GLP1 agonists reduced the incidence of all-cause mortality by 12%. In addition, hospitalization or urgent medical visit for heart failure was decreased by 10%. In terms of renal asessment, the composite of kidney function was reduced by 22%, while the manifestation of acute renal injury/failure, though no statistical signification was accomplished, showed some evidence of beneficial effect but more RCTs are needed to prove it. Hence, GLP1 analogues appear as a possible new pillar of treatment for heart failure and renal disease in determined patients.

Bidirectional relationship between kidney disease progression and cardiovascular events in type 2 diabetes: new Insights from the CANVAS Program and CREDENCE trial

Abstract Background The extent to which chronic kidney disease (CKD) progression increases cardiovascular risk, and whether different types of cardiovascular events affect risk of CKD progression, is incompletely understood. Purpose We sought to explore risk of cardiovascular events before and after CKD progression, and CKD progression before and after different cardiovascular events in patients with type 2 diabetes. Methods We conducted a pooled individual participant data analysis of the CANVAS Program and CREDENCE trial. Using Poisson regression, we assessed the incidence of major adverse cardiovascular events ([MACE] stroke, myocardial infarction, or cardiovascular death) and hospitalised heart failure (HHF) or cardiovascular death before and after CKD progression (defined as 40% decline in estimated glomerular filtration rate [eGFR] or kidney failure), and CKD progression before and after nonfatal cardiovascular events, with no adjustment for confounding related to subgroups defined by post-randomization variables. We estimated the cumulative incidence of all-cause mortality after different nonfatal cardiovascular and kidney outcomes, including different thresholds of CKD progression (kidney failure, 40% or 50% decline in eGFR or doubling of serum creatine) using Cox regression models. Results Among 14,464 participants (mean age 63.7 years, 35.3% female, mean eGFR 55mL/min/1.73m2 and median urinary albumin:creatinine ratio 34mg/g) over a median follow-up of 2.5 years, 1,482, 1,076 and 1,020 experienced MACE, HHF or cardiovascular death, and CKD progression, respectively. After (vs. before) CKD progression, there was an approximate 3-fold increase in incidence of MACE (30.2 vs. 93.8 per 1000-patient-years) and 4-fold increase in HHF or cardiovascular death (21.0 vs. 79.3 per 1000-patient-years). Conversely, the incidence of CKD progression was approximately 1.5-fold higher after (vs. before) nonfatal myocardial infarction or stroke (21.7 vs. 34.1 per 1000-patient-years) and 5-fold higher after HHF (21.2 vs. 108.2 per 1000-patient-years). These patterns were consistent in both treatment arms, with unadjusted incidence rates for clinical events appearing numerically lower in canagliflozin compared to placebo-treated participants (Figure 1). Of all non-fatal cardio-kidney outcomes, HHF and doubling of serum creatine or kidney failure conferred the highest risk of death (Figure 2). Conclusion Atherosclerotic and heart failure risk increases substantially after CKD progression. CKD progression was accelerated after cardiovascular events, particularly HHF. Treatment with canagliflozin was associated with lower event rates before and after a serious cardio-kidney outcome, suggesting continued use of canagliflozin may be beneficial even after cardiovascular events and CKD progression.Figure 1.Figure 2.

Antithrombotic strategies after cryptogenic stroke: a systematic review, pairwise, and network meta-analysis of randomized controlled trials

Abstract Background No definite etiology is identified in 30-40% of ischemic stroke cases, which is known as cryptogenic stroke. Several antithrombotic strategies have been investigated for cryptogenic stroke management; however, the optimal strategy remains unknown. Purpose We aim to assess the efficacy and safety of oral anticoagulants (OACs) versus aspirin, and the comparative efficacy and safety of different OACs after cryptogenic stroke. Methods A systematic review and meta-analysis synthesizing evidence from randomized controlled trials (RCTs) obtained from PubMed, Embase Cochrane, Scopus, and WOS until February 2024. We used the fixed-effects model to report dichotomous outcomes using a risk ratio (RR), with a 95% confidence interval (CI). Analysis was conducted using R, version 4.2.0. Results Seven RCTs with 15.240 patients were included. In pairwise analysis, there was no difference between OACs and aspirin regarding all-cause mortality (RR: 1.13, CI [0.89, 1.43], P= 0.33) and stroke recurrence (RR: 0.93, CI [0.82, 1.07], P= 0.31). However, OACs were associated with a significantly increased incidence of major bleeding (RR: 1.6, CI [1.24, 2.05], P= 0.01), with no difference regarding the incidence of intracranial hemorrhage (RR: 1.09, CI [0.3, 3.97], P= 0.9). Moreover, in network analysis, none of the OACs showed a significant efficacy in preventing all-cause mortality and stroke recurrence compared to aspirin. However, only rivaroxaban significantly increased the incidence of major bleeding (RR: 2.69, CI [1.67, 4.33]). Conclusion OACs did not protect against stroke recurrence or decrease the incidence of all-cause mortality but increased the incidence of major bleeding in patients with cryptogenic stroke.

Drug-use-associated infective endocarditis in Denmark

Abstract Introduction Infective endocarditis (IE) has high mortality and the incidence is rising. Intravenous drug use is a risk factor for IE and poses challenges in clinical care. Amid the opioid crisis in many countries, rates of drug-use-associated IE (DU-IE) are increasing. While drug use in Denmark has remained stable the last decade, little is understood about the features and prognostic impact of DU-IE in developed nations not facing a current opioid crisis. Further, with multiple preventive measures deployed in local Danish regions, data on the evolution of DU-IE are warranted. Purpose To examine the temporal evolution, baseline characteristics, and long-term rates of all-cause mortality and IE recurrence in patients with DU-IE compared with patients with non-DU-IE. Methods This nationwide cohort study identified all first-time IE-patients (1999-2018) and categorized them in 1) patients with DU-IE, and 2) patients with non-DU-IE. Drug use was defined using ICD-8/10 codes or treatment for opioid use disorder. Patients were followed from the date of discharge, and absolute one-year rates of mortality and IE recurrence were examined with Kaplan-Meier estimates and the cumulative incidence function, respectively. Outcomes were compared with a multivariable adjusted Cox model. Results We identified 8,843 patients with IE: 407 (4.6%) with DU-IE (61% male, median age 44 years) and 8,436 (95.4%) with non-DU-IE (66% male, median age 72 years). While the absolute number of DU-IE increased, the proportion of DU-IE decreased from 5.9% in 1999-2003 (n=87) to 3.8% in 2014-2018 (n=114). Patients with DU-IE had a higher proportion of bloodstream infection with Staphylococcus aureus (49.4% vs 26.7%, p&amp;lt;0.001); conversely, they had a lower proportion of bloodstream infections with Streptococcusspecies (14.4% vs. 26.2%, p&amp;lt;0.011). Patient with DU-IE had lower in-hospital mortality compared with non-DU-IE (15.5% vs. 20.9%, p&amp;lt;0.001). Among those surviving admission, the one-year cumulative incidence of all-cause mortality was 16.9% in DU-IE and 17.3% in non-DU-IE (p=0.82), yet in adjusted analysis, DU-IE was associated with a higher one-year mortality rate (HR 1.64 [95% CI:1.23-2.21]) (Figure). The one-year cumulative incidence of IE recurrence was 12.8% in DU-IE and 4.3% in non-DU-IE, which corresponded to an adjusted HR of 3.39 (95% CI:2.35-4.88) in DU-IE. Conclusion While an increase in the absolute number of patients with DU-IE was observed, the proportion among all IE-patients was on the decline in Denmark until 2018—which contrasts with other countries where physicians currently battle collateral damage of the opioid crisis. Although drug use was associated with lower in-hospital mortality, it was striking that even though patient with DU-IE was almost 30 years younger, they still had higher rates of all-cause mortality and a more than three-fold increase in IE recurrence one year following discharge.

The efficacy and safety of GLP-1 agonists to modify cardiovascular morbidity in patients with obesity without diabetes mellitus: a meta-analysis involving 32,884 patients

Abstract Background While the cardioprotective effects of glucagon-like peptide -1 (GLP-10) agonists are well-documented in diabetic patients, their impact on cardiovascular outcomes in patients with obesity without diabetes mellitus remains debated. Purpose This systematic review and meta-analysis of randomized controlled trials (RCTs) was conducted to investigate the effects of GLP-1 on cardiovascular outcomes in patients with obesity without diabetes mellitus. Methods A systematic review and meta-analysis synthesizing RCTs were retrieved by systematically searching PubMed, Web of Science, SCOPUS, and Cochrane through December 26th, 2023. Dichotomous data were pooled using risk ratio (RR) and continuous data using mean difference (MD) with a 95% confidence interval (CI). Results We included 19 RCTs with a total of 32,884 patients. There was no difference between GLP-1 agonists and placebo regarding cardiovascular mortality (RR: 0.85, 95% CI [0.71- 1.01], P= 0.07). However, GLP-1 agonists significantly decreased the incidence of all-cause mortality (RR 0.83, 95% CI 0.72 to 0.94, p &amp;lt; 0.0001), non-cardiovascular mortality (RR 0.78, 95% CI 0.63 to 0.96, p = 0.02), and myocardial infarction (RR 0.73, 95% CI 0.62 to 0.87, p &amp;lt; 0.0001). Also, GLP-1 agonists significantly increased the incidence of any adverse events (RR 1.11, 95% CI 1.05 to 1.16, p &amp;lt; 0.0001), with no difference regarding the incidence of serious adverse events. Conclusion GLP-1 agonists not only demonstrated substantial benefits in reducing cardiovascular risks, including all-cause mortality and myocardial infarction, but also effectively promoted weight loss and improved lipid profiles and blood pressure control. However, their use is accompanied by a higher incidence of gastrointestinal adverse effects and heterogeneity in outcomes, highlighting the need for individualized treatment approaches.

Validation of the MIDA mortality risk score in a surgical cohort of patients with primary mitral regurgitation

Abstract Background and aim The MIDA scale is a prognostic tool for stratification of short- and long-term mortality risk in patients with primary mitral regurgitation (PMR). The aim of this study is to validate the MIDA (1) score in our population of PMR treated with surgery. Methods Retrospective analysis of a prospective cohort of patients with PMR who underwent mitral valve surgery in a tertiary care center from 2014 to 2022. The necessary parameters for calculating the MIDA Score (age, symptoms, atrial fibrillation, left atrial diameter, right ventricular systolic pressure (RVSP), left ventricular end-systolic diameter (LVESD), and LV ejection fraction (LVEF)) were collected, and the MIDA score for each patient was calculated. Thereafter, patients were classified into seven different risk groups. One year and long-term mortality during follow-up were recorded. A logistic regression analysis was performed to evaluate the association of each parameter with outcomes. Finally, curves for the cumulative incidence of all-cause mortality according to the MIDA score were generated with the Kaplan–Meier method. Results A total of 349 patients were included. Mean age was 68.5 [12.4] years, 55.8% were male, and the median LVEF was 60% (55-65). Mean follow up was 3.28 (2) years. One year mortality occurred in 29 (8.3%) patients, and long-term mortality in 59 (16.9%). According to the MIDA score, the distribution of patients in each subgroup was as follows: score 0 (n=28), score 1-2 (n=35), score 3-4 (n=60), score 5-6 (n=99), score 7-8 (n=81), score 9-10 (n=35), score &amp;gt; 11 (n=11). Most of our cohort was classified as intermediate-risk patients, with a median score of 6 (3-8). In the univariable logistic regression analysis, age, symptoms before surgery and RVSP were the only MIDA parameters significantly associated with mortality (Table-Figure 1). In our population, the discriminatory capacity of the MIDA score, was moderate, with an area under the ROC curve of 0.676 CI (0.624-0.725) for one year mortality, and 0.702 (0.651-0.749) for long term mortality. The best cut-off point for predicting one-year and long-term mortality was a MIDA score of 7. Kaplan-Meier curves for mortality during follow-up are shown in Figure 2. Conclusions The MIDA score showed a fair discriminatory capacity in our surgical cohort of patients with PMR. Variables included in the score that had a significant association with mortality were age, presence of symptoms and elevated RVSP. LV parameters included in the MIDA, which are the current class I indication for surgery, did not show a significant association with outcomes. Different echocardiographic variables to evaluate cardiac damage in PMR are needed to achieve better stratification.Table-Figure 1Figure 2
