Initial hemodynamic status and Acute Mortality in Cancer patients with Acute Pulmonary Embolism: from the COMMAND VTE Registry.

Initial hemodynamic status in patients with acute pulmonary embolism (PE) concerns their acute clinical outcomes. Nevertheless, the characteristics of initial hemodynamic dysfunction and acute mortality in PE patients with active cancer is still controversial. We analyzed the data of 1715 PE patients in the COMMAND VTE Registry to compare initial hemodynamic dysfunction, management strategies, and mortality outcomes at 30 days after PE diagnosis between patients with and without active cancer (N = 393 and N = 1322). The patients with active cancer showed lower prevalence of right ventricular dysfunction (35.4% vs. 49.5%, P < 0.001), shock (6.4% vs. 11.6%, P = 0.003), and cardiac arrest (1.8% vs. 5.5%, P = 0.002) at PE diagnosis, compared with those without. The patients with active cancer less frequently received systemic thrombolysis (4.1% vs. 12.6%, P < 0.001) than those without. There was no significant difference in the cumulative 30-day incidence of PE-related death between patients with and without active cancer (4.1% vs. 4.2%, P = 0.89). The cumulative 30-day incidence of all-cause death was significantly higher in patients with active cancer than in those without (11.5% vs. 4.9%, P < 0.001). PE patients with active cancer less frequently present with initial hemodynamic dysfunction at PE diagnosis, compared with those without. Nevertheless, PE patients with active cancer still show a similar risk of PE-related death and a higher risk of all-cause death at 30 days after PE diagnosis, suggesting the importance of prudent management for this patient population even if their initial hemodynamic status are not compromised.

Cardiac arrest and cardiogenic shock complicating ST-segment elevation myocardial infarction in China: A retrospective multicenter study

BackgroundData on the effect of cardiac arrest (CA), cardiogenic shock (CS), and their combination on the prognosis of Chinese patients with ST-segment elevation myocardial infarction (STEMI) are limited. The present study sought to evaluate the clinical outcomes of STEMI complicated by CA and CS, and to identify the risk factors for CA or CS. MethodsThis study included 7468 consecutive patients with STEMI in China. The patients were divided into 4 groups (CA + CS, CA only, CS only, and No CA or CS). The endpoints were 30-day all-cause death and major adverse cardiovascular events. A Cox proportional hazards regression analysis was performed. ResultsCA, CS, and their combination were noted in 332 (4.4 %), 377 (5.0 %), and 117 (1.6 %) among all patients. During the 30-day follow-up, 817 (10.9 %) all-cause deaths and 964 (12.9 %) major adverse cardiovascular events occurred, and the incidence of all-cause mortality (3.6 %, 62.3 %, 74.1 %, 83.3 %) and major adverse cardiovascular events (5.4 %, 67.1 %, 75.0 %, and 87.2 %) significantly increased in the No CA or CS, CS only, CA only, and CA + CS groups, respectively. In the multivariate Cox regression models, compared with the No CA or CS group, the CA + CS, CA, and CS-only groups were associated with an increased risk of all-cause death and major adverse cardiovascular events. Patients with CA + CS had the highest risk of all-cause death (hazard ratio [HR], 25.259 [95 % confidence interval (CI) 19.221–33.195]) and major adverse cardiovascular events (HR 19.098, 95%CI 14.797–24.648). ConclusionsCA, CS, and their combination were observed in approximately 11 % of Chinese patients with STEMI, and were associated with increased risk for 30-day mortality and major adverse cardiovascular events in Chinese patients with STEMI.

Echocardiographic Parameters of Left Atrial Structure and Function and Clinical Outcomes at 2 Years in Elderly Patients With Atrial Fibrillation - The ANAFIE Echocardiographic Substudy.

This prospective ANAFIE Registry substudy investigated the relationship between the echocardiographic parameters of left atrial (LA) structure and function and clinical outcomes at 2 years among atrial fibrillation (AF) patients aged ≥75 years.Methods and Results: Outcomes of 1,474 elderly non-valvular AF (NVAF) patients who underwent transthoracic echocardiography at baseline were analyzed by categories of maximum LA volume index (max. LAVi) and LA emptying fraction (LAEF) total. Baseline mean±standard deviation LAEF total and max. LAVi were 28.2±14.9% and 54.2±25.9 mL/m2, respectively. Proportions of oral anticoagulant (OAC), direct OAC, and warfarin use were 92.7%, 68.7%, and 24.0%, respectively. Patients with LAEF total ≤45.0% (n=1,213) vs. >45.0% (n=224) were at higher risk of cardiovascular events (hazard ratio [HR]: 2.19, P=0.021) and heart failure (HF) hospitalization (HR: 2.25, P=0.045). Risk of all-cause death was higher with max. LAVi >48.0 mL/m2(n=656) vs. ≤48.0 mL/m2(n=621) (HR: 1.69, P=0.048). Subgroups with abnormal LA function and structure had increased incidence of cardiac/cardiovascular events and HF hospitalization. No significant interaction was observed between echocardiographic parameters and OAC type. Elderly Japanese patients with NVAF and LAEF total ≤45.0% were at higher risk of cardiovascular events and HF hospitalization, and those with max. LAVi >48.0 mL/m2were at higher risk of all-cause death.

Predictive value of the controlling nutritional status (CONUT) score to assess long-term mortality (10 Years) in patients with hypertension

Background and aimsMalnutrition is associated with poor outcomes in patients with chronic diseases. Aim of this study is to investigate the prevalence of malnutrition in patients with hypertension and relationship between malnutrition severity and long-term mortality in these patients. Methods and resultThe study included 11,278 patients with hypertension from the National Health and Nutrition Examination Survey database. The degree of malnutrition was assessed using the Controlled Nutritional Status score, with patients divided into normal, mild, and moderate-to-severe groups. After 10 years of follow-up, the results showed that patients who died had higher CONUT scores, poorer nutritional status, and lower albumin, total cholesterol, and lymphocyte counts than those who survived (P < 0.05). The Kaplan–Meier analysis revealed that patients with poor nutritional status had a significantly higher risk of all-cause death. In the Non-Lipid Lowering Drugs group, the CONUT score (hazard ratio (HR): 1.225; 95% confidence interval (CI): 1.162–1.292; P < 0.0001), as well as mild (HR: 1.532; 95% CI 1.340–1.751; P < 0.0001) and moderate-to-severe malnutrition (HR: 2.797; 95% CI: 1.441–5.428; P = 0.0024), were independent predictors of long-term mortality. The competing risk regression models showed that cardiovascular and cerebrovascular mortality increased with increasing CONUT scores. The results were robust in both subgroup and sensitivity analyses. ConclusionMalnutrition significantly impacts long-term mortality in hypertensive patients. The CONUT score may be a useful tool for assessing the nutritional status of patients with hypertension in the non-lipid-lowering population and for predicting their long-term mortality.

Prognostic Value of Aortic Valve Calcification in Nonsevere Aortic Stenosis with Preserved Ejection Fraction.

Aortic valve calcification(AVC) is prognostic in patients with aortic stenosis(AS). We assessed the AVC prognostic value in nonsevere AS patients. We conducted a retrospective study of 395 patients with nonsevere AS, LV ejection fraction ≥50%. The Agatston method was used for computed tomography AVC assessment. The log-rank test determined the best AVC cutoffs for survival under medical surveillance: 1185 AU in men and 850 in women, lower than the established-cutoffs for severe AS(2064AU in men and 1274 in women). Patients were divided into three AVC groups based on these cutoffs: low(<1185 AU men and <850 women), sub-severe(1185-2064AU men and 850-1274 women) and severe(>2064AU men and >1274 women). Of 395 patients(mean age 73 ± 12 years, 60.5% men, aortic valve area 1.23 ± 0.30cm2, mean pressure gradient 28 ± 8 mmHg), 218 underwent aortic valve intervention(AVI) and 158 deaths occurred during follow-up, 82 before AVI. Median survival time under medical surveillance was 2.1[0.7-4.9]years. Compared to the low AVC group, both sub-severe and severe AVC groups had higher risk for all-cause death under medical surveillance after comprehensive adjustment including echocardiographic AS severity and coronary artery calcium score(all p ≤ 0.006); while mortality risk was similar between sub-severe and severe AVC groups(all p ≥ 0.2). This mortality risk pattern persisted in the overall survival analysis after adjustment for AVI. AVI was protective of all-cause death in the sub-severe and severe AVC(all p ≤ 0.01), but not in the low AVC groups. Sub-severe AVC is a robust risk-stratification parameter in patients with nonsevere AS and may inform AVI timing.

Breast cancer polygenic risk score and patient survival outcomes in the Pathways study.

10502 Background: Many common, low-penetrance variants have been identified for breast cancer risk through genome-wide association studies, leading to the development of polygenic scores (PGS) to aggregate the effects of individual variants for risk prediction. Much less is known about genetic determinants of breast cancer-related outcomes. We hypothesized that breast cancer patients with high breast cancer PGS are at risk of a second breast-related adverse event, such as recurrence, contralateral breast cancer, or death. Methods: The Pathways Study is a prospective cohort study of breast cancer survivors enrolled shortly after diagnosis in 2006-2013 at Kaiser Permanente Northern California, with ongoing follow-up. Genome-wide genotype data were available from 3,995 patients for calculation of 4 PGS, including PGS313, PGS4k, PGS5k, and PGS6m. Scores were categorized into tertiles to investigate their associations with 7 survival outcomes including recurrence, contralateral second primary breast cancer, other second primary cancer, and death. Hazard ratios (HR) and 95% confidence intervals (CI) were derived from multivariable Cox proportional hazards regression models. Results: The median age at diagnosis was 60 (23.6-94.8) years, and most (68%) self-identified as White. Many women had estrogen receptor (ER)+ (83.4%), stage I and II tumors (89%), with 13.3% HER2+ tumors. The majority (60%) received lumpectomy and some type of adjuvant therapy (44.3% radiotherapy, 47.0% chemotherapy, and 74.6% received hormonal therapy). By December 31, 2021, the median follow-up time was 10.5 (0.2-14.2) years, with 504 recurrences, 419 total second primary cancers, 146 contralateral second primary breast cancers, 237 non-breast second primary cancers, and 762 deaths (352 breast cancer-specific deaths) observed. In Table 1, patients with medium (T2) and high (T3) PGS313 had higher risk of recurrence, but not contralateral breast cancer or other second primary cancer. They also had higher risk of all-cause death, breast cancer-specific death, total breast cancer event, and invasive disease. The other 3 PGS were not associated with survival outcomes examined. Conclusions: Our study reveals that breast cancer patients with higher PGS313 had higher risk of recurrence, total breast cancer and invasive breast cancer events, and death. These findings highlight a potential role of breast cancer PGS for prognosis, warranting further exploration. [Table: see text]

Risk of death, thrombotic and hemorrhagic events in patients with atrial fibrillation and systemic autoimmune diseases

Abstract Background Growing evidence showing that systemic autoimmune diseases (SAD) are associated with a high risk of incident atrial fibrillation (AF). However, the impact of SAD on the clinical course of AF patients is largely unknown. Purpose To assess the risk of all-cause death, thrombotic events, and bleeding in AF patients with SAD. Methods Retrospective cohort study within a global health care network (TriNetx). Using ICD codes, AF patients were categorized into two groups: 1) AF patients with SAD (M32: Systemic Lupus Erythematosus; M33: Dermato-polymyositis; M34: Systemic Sclerosis; M35: Sjogren syndrome), and 2) AF controls (without systemic autoimmune, autoinflammatory, or rheumatic diseases). The primary outcomes were the 5-year risks of 1) all-cause death, 2) thrombotic events (ischemic stroke, transient ischemic attack, peripheral arterial thromboembolism, acute myocardial infarction, deep vein thrombosis, and pulmonary embolism), and 3) hemorrhagic outcome (intracranial hemorrhage and gastrointestinal bleeding). Secondary outcomes were each component of the composite primary outcomes. Cox regression analysis before and after propensity-score-matching (PSM) was used to estimate HR and 95% confidence interval (95%CI). Sensitivity analyses were done to investigate the risk of primary outcomes associated with each systemic autoimmune disease and with different types of oral anticoagulant (OAC). Results We identified 22,371 AF patients with SAD (67.7±13.7 years, 72.2% females), and 1,478,693 AF controls (69.7±14.0, 42.6% females). Before PSM, AF patients with SAD were younger, more often females, and with a higher prevalence of cardiovascular risk factors; no differences were found after PSM. After PSM, AF patients with SAD showed a higher risk of all-cause death (HR 1.21, 95% 1.17-1.25), thrombotic events (HR 1.55, 95%CI 1.49-1.61), and hemorrhagic events (HR 1.39, 95%CI 1.32-1.46) compared to AF controls (Table 1). On sensitivity analyses, we found that the risk of primary outcomes in AF patients with SAD was independent from the OAC type, but NOAC was more effective than warfarin in reducing the risk of thrombotic events. The highest risk of all-cause death was associated with Systemic Sclerosis, while the highest risk of composite thrombotic events was associated with Systemic Lupus Erythematosus, and Dermato-polymyositis. The highest risk of stroke was associated with Sjogren syndrome; and myocardial infarction and deep vein thrombosis with Dermato-polymyositis, Systemic Lupus Erythematosus was associated with the highest risk of Intracranial hemorrhage, while Systemic Sclerosis to the highest risk of gastrointestinal bleeding (Table 2). Conclusion In AF patients the coexistence of SAD is associated with a high risk of all-cause death, thrombotic events, and bleeding. A personalized approach aimed to minimize the impact of SAD on the clinical course of AF patients is needed.Figure 1Figure 2

Prognostic value of geriatric nutritional risk index in patients with stable coronary artery disease undergoing percutaneous coronary intervention

BackgroundMalnutrition increases the risk of poor prognosis in patients with cardiovascular disease, and our current research was designed to assess the predictive performance of the Geriatric Nutrition Risk Index (GNRI) for the occurrence of poor prognosis after percutaneous coronary intervention (PCI) in patients with stable coronary artery disease (SCAD) and to explore possible thresholds for nutritional intervention.MethodsThis study retrospectively enrolled newly diagnosed SCAD patients treated with elective PCI from 2014 to 2017 at Shinonoi General Hospital, with all-cause death as the main follow-up endpoint. Cox regression analysis and restricted cubic spline (RCS) regression analysis were used to explore the association of GNRI with all-cause death risk and its shape. Receiver operating characteristic curve (ROC) analysis and piecewise linear regression analysis were used to evaluate the predictive performance of GNRI level at admission on all-cause death in SCAD patients after PCI and to explore possible nutritional intervention threshold points.ResultsThe incidence of all-cause death was 40.47/1000 person-years after a mean follow-up of 2.18 years for 204 subjects. Kaplan-Meier curves revealed that subjects at risk of malnutrition had a higher all-cause death risk. In multivariate Cox regression analysis, each unit increase in GNRI reduced the all-cause death risk by 14% (HR 0.86, 95% CI 0.77, 0.95), and subjects in the GNRI > 98 group had a significantly lower risk of death compared to those in the GNRI < 98 group (HR 0.04, 95% CI 0.00, 0.89). ROC analysis showed that the baseline GNRI had a very high predictive performance for all-cause death (AUC = 0.8844), and the predictive threshold was 98.62; additionally, in the RCS regression analysis and piecewise linear regression analysis we found that the threshold point for the GNRI-related all-cause death risk was 98.28 and the risk will be significantly reduced when the subjects' baseline GNRI was greater than 98.28.ConclusionsGNRI level at admission was an independent predictor of all-cause death in SCAD patients after PCI, and GNRI equal to 98.28 may be a useful threshold for nutritional intervention in SCAD patients treated with PCI.

Hematocrit Predicts Poor Prognosis in Patients with Acute Ischemic Stroke or Transient Ischemic Attack.

This study aims to investigate the association between HCT (Hematocrit) levels and adverse outcomes in patients with acute ischemic stroke (AIS) or transient ischemic attack (TIA); 14,832 participants from the China National Stroke Registry-III with AIS or TIA were analyzed. Participants were categorized into quartiles based on baseline HCT levels. The primary outcome was poor functional outcomes (modified Rankin Scale ≥ 3) during three months, with secondary outcomes including all-cause death, stroke recurrence, and combined vascular events. Logistic regression or Cox regression models were used to assess the relationship between HCT and clinical outcomes. Compared to the third quartile, patients in the lowest quartile group showed increased risk of poor functional outcome (adjusted OR: 1.35, 95% CI: 1.15-1.58, p < 0.001), patients in the lowest quartile had a higher risk of all-cause death (adjusted HR: 1.68, 95% CI: 1.06-2.68, p = 0.028), as did those in the highest quartile (adjusted HR: 2.02, 95% CI: 1.26-3.25, p = 0.004). Sensitivity analysis shows that the association of HCT with all-cause death weakened, while the association with poor functional outcome was strengthened after excluding patients with recurrent stroke. Our results indicated that HCT level could be used as a short-term predictor for poor functional outcomes and all-cause death in patients with AIS or TIA.

Prognostic Implication of Right Ventricular Free Wall Longitudinal Strain and Right Atrial Pressure Estimated By Echocardiography in Patients With Severe Functional Tricuspid Regurgitation.

The interaction between right ventricular (RV) function and pulmonary hypertension is crucial for prognosis of patients with severe functional tricuspid regurgitation. RV free wall longitudinal strain (RVFWLS) has been reported to detect RV systolic dysfunction earlier than other conventional parameters. Although pulmonary artery systolic pressure measured by Doppler echocardiography is often underestimated in severe functional tricuspid regurgitation, right atrial pressure (RAP) estimated by echocardiography may be viewed as a prognostic factor. Impact of RAP and RVFWLS on outcome in patients with severe functional tricuspid regurgitation remains unclear. The aim of the present study was to investigate prognostic implication of RAP, RVFWLS, and their combination in this population. We retrospectively examined 377 patients with severe functional tricuspid regurgitation. RAP, pulmonary artery systolic pressure, RV fractional area change, and RVFWLS were analyzed. RAP of 15 mm Hg was classified as elevated RAP. All-cause death at 2-year follow-up was defined as the primary end point. RVFWLS provided better prognostic information than RV fractional area change by receiver operating characteristic curve analysis. In the multivariable Cox regression analysis, elevated RAP and RVFWLS of ≤18% were independent predictors of clinical outcome. Patients with RVFWLS of ≤18% had higher risk of all-cause death than those without by Kaplan-Meier curve analysis. Furthermore, when patients were stratified into 4 groups by RAP and RVFWLS, the group with elevated RAP and RVFWLS of ≤18% had the worst outcome. Elevated RAP and RVFWLS of ≤18% were independent predictors of all-cause death. The combination of elevated RAP and RVFWLS effectively stratified the all-cause death.

Prognostic impact of frailty based on a comprehensive frailty assessment in patients with heart failure.

This study aimed to evaluate the impact of frailty and living function domains based on the Kihon Checklist (KCL), a questionnaire for a comprehensive frailty assessment, on prognosis in patients with acute heart failure (AHF). The Kochi Registry of Subjects with Acute Decompensated Heart Failure (Kochi YOSACOI) study was a prospective multicentre cohort study enrolling 1061 patients hospitalized for AHF from May 2017 to December 2019 in Japan. We divided patients into three groups according to the severity of frailty using the KCL and compared clinical outcomes after discharge. The primary endpoint was all-cause death, and the secondary outcomes were cardiovascular death, heart failure (HF) rehospitalization, and the composite event of cardiovascular death and HF rehospitalization. Of 936 patients (median age, 81years; 48.9% women) who could be assessed for frailty, we identified frailty in 501 patients (53.5%), prefrailty in 290 patients (31.0%), and non-frailty in 145 patients (15.5%). Compared with prefrail and non-frail patients, frail patients were older (83 vs. 79 and 72years, P<0.001), were more likely to be women (53.9% vs. 43.1% and 43.4%, P=0.005), and were more likely to have a history of previous HF hospitalization (35.4% vs. 25.3% and 19.6%, P<0.001) and multimorbidity (90.8% vs. 81.0% and 73.8%, P<0.001). Frail patients had a lower rate of discharge to home (79.7% vs. 94.8% and 96.5%, P<0.001). During the 2year follow-up period, frail patients had a higher incidence rate of all-cause death, cardiovascular death, and HF rehospitalization (log-rank P<0.001, P<0.001, and P=0.003, respectively). After adjusting for other prognostic factors, multivariate analysis showed that frailty was associated with all-cause death [adjusted hazard ratio (HR): 2.917, 95% confidence interval (CI): 1.326-6.417, P=0.008] and cardiovascular death (adjusted HR: 7.026, 95% CI: 1.700-29.030, P=0.007). Among all domains of the KCL, the cognitive function domain was associated with a higher risk of all-cause death (P=0.004) and cardiovascular death (P<0.001). The depression domain remained associated with a higher risk of HF rehospitalization (P=0.045). The risk for all-cause death increased with an increase in total KCL score (adjusted HR: 1.819, 95% CI: 1.300-2.547, P<0.001). The KCL is a useful tool for risk stratification of adverse outcomes in patients with AHF. Functional declines in psycho-emotional domains including cognitive function and depressed mood contribute to adverse outcomes.

Predictive value of the prognostic nutritional index combined with serum chloride levels for the prognosis of patients with acute decompensated heart failure

BackgroundThe prognostic nutritional index (PNI) and serum chloride level are related to adverse outcomes in patients with heart failure. However, little is known about the relationship between the PNI and serum chloride level in predicting the poor prognosis of patients with acute decompensated heart failure (ADHF).Methods and resultsWe reviewed 1221 consecutive patients with ADHF admitted to the First Affiliated Hospital of Kunming Medical University from January 2017 to October 2021. After excluding patients with in hospital death, missing follow-up data, missing chloride data, missing lymphocyte (LYM) count data, or missing serum albumin data, 805 patients were included. PNI was calculated using the formula: serum albumin (ALB) (g/L) + 5 × LYM count (10^9/L). Patients were divided into 4 groups according to the quartiles of the PNI, and the highest PNI quartile (PNI Q4: PNI ≥ 47.3) was set as the reference group. The patients in the lowest PNI quartile (PNI Q1: PNI < 40.8) had the lowest cumulative survival rate, and mortality risk decreased progressively through the quartiles (log-rank χ2 142.283, P < 0.0001). Patients with ADHF were divided into 8 groups by quartiles of PNI and median levels of serum chloride. After adjustment, the hazard ratio (HR) for all-cause mortality in ADHF patients in Group 1 was 8.7 times higher than that in the reference Group 8. Furthermore, the addition of serum chloride level and PNI quartile to the Cox model increased the area under the Receiver operating characteristic (ROC) curve by 0.05, and the area under the ROC curve of the new model was higher than that of the original model with traditional risk factors.ConclusionsBoth the lowest PNI quartiles and low chloride level indicate a higher risk of all-cause death in patients with ADHF.

Risk stratification by systemic manifestations secondary to hemodynamic disorders of patients with severe tricuspid regurgitation

BackgroundTricuspid regurgitation (TR) is a prevalent disease that triggers systemic pathological changes including cardiac, respiratory, hepatic and digestive, hematopoietic, renal and skin issues. The burden of extra-cardiac manifestations has not been well described in TR patients and the clinical impact is unknown.MethodsPatients with severe or more-than-severe TR during hospitalization, who did not have any previous cardiac procedures, hemodynamically significant congenital heart disease or concomitant severe aortic or mitral valve disease, were retrospectively analyzed. Pre-specified criteria and diagnosis of baseline characteristics were used to evaluate the presence of extra-cardiac manifestations secondary to TR after excluding comorbidities that may also lead to corresponding abnormalities. Extra-cardiac involvements encompass respiratory, hepatic and, digestive, renal, hematopoietic and dermatic system. Staging criteria are defined as no extra-cardiac system involvement in Stage 1, one in Stage 2, at least two extra-cardiac involvements in Stage 3 and any end-stage organ failure in Stage 4. A telephone follow-up was conducted to record the composite endpoint namely all-cause death or cardiac rehospitalization after the index hospitalization.ResultsA total of 258 patients were identified with a median age of 73 (interquartile range [IQR]: 62–83) years and 52.3% were female. Severe TR and more-than-severe TR patients accounted for 92.6% and 7.4% of the cohort. There were 20.5%, 27.5%, 37.6% and 14.3% of patients from Stage 1 to 4 respectively. The follow-up time was at a median of 251 (IQR: 183–324) days. TR Patients in Stage 3&4 were at an increased risk with borderline statistical significance to experience the composite endpoint compared to patients in Stage 1&2 (odds ratio [OR] 1.9, 95% confidence interval [CI] 1.0 to 3.7, P = 0.049).ConclusionsApproximately half of patients with at least severe TR presented with two or more extra-cardiac systemic manifestations, which may incur a 1.9-fold higher risk of all-cause death or cardiac rehospitalization than TR patients with one or less extra-cardiac involvement.

Risk of death, thrombotic and hemorrhagic events in anticoagulated patients with atrial fibrillation and systemic autoimmune diseases: an analysis from a global federated dataset

BackgroundGrowing evidence showing that systemic autoimmune diseases (SADs) are associated with a high risk of atrial fibrillation (AF). However, the impact of SAD on the clinical course of AF patients is largely unknown.MethodsRetrospective cohort study within a federated healthcare network (TriNetX). Using ICD codes, AF patients on anticoagulant therapy were categorized according to the presence of SAD (M32: Systemic Lupus Erythematosus (SLE); M33: Dermato-polymyositis (DMP); M34: Systemic Sclerosis (SSc); M35: Sjogren syndrome). The primary outcomes were the 5-year risks of (1) all-cause death, (2) thrombotic events (ischemic stroke, acute myocardial infarction, deep vein thrombosis, and pulmonary embolism), and (3) bleeding (intracranial (ICH) and gastrointestinal (GI)). Secondary outcomes were each component of the primary outcomes. Cox regression analysis after propensity score matching (PSM) was used to estimate hazard ratio (HR) and 95% confidence interval (95%CI).ResultsWe identified 16,098 AF patients with SAD (68.2 ± 13.4 years; 71.0% female) and 828,772 AF controls (70.7 ± 12.9 years, 41.1% females). After PSM, AF patients with SAD were associated with a higher risk of all-cause death (HR 1.13, 95%CI 1.09–1.71), thrombotic events (HR 1.37, 95%CI 1.32–1.43), and hemorrhagic events (HR 1.41, 95%CI 1.33–1.50) compared to AF controls without SAD. The highest risk of all-cause death and GI bleeding was associated with SSc, while the highest risk of thrombotic events and ICH was associated with SLE.ConclusionAF patients with SAD are associated with a high risk of all-cause death, thrombotic, and hemorrhagic events. These patients merit careful follow-up and integrated care management to improve their prognosis.Graphical

Evaluation of the Prognostic Role of Neutrophil-Lymphocyte Ratio, C-Reactive Protein-Albumin Ratio, and Platelet-Lymphocyte Ratio in Patients with the Co-Presentation of Coronary Artery Disease and COVID-19.

The purpose of this study was to investigate the role of neutrophil-lymphocyte ratio (NLR), C-reactive protein-albumin ratio (CAR), and platelet-lymphocyte ratio (PLR) in the prognosis of patients with coronary artery disease (CAD) complicated with coronavirus disease 2019 (COVID-19). This study included 265 patients. A receiver operating characteristic (ROC) curve analysis was performed to preliminarily evaluate the predictive ability of NLR, CAR, and PLR for all-cause death. The primary outcome was all-cause death during hospitalization, while the secondary outcomes were cardiovascular death and respiratory failure death. The Cox proportional hazard model with adjusted covariates was used to analyze the cumulative risk of outcomes. We also conducted subgroup analyses based on the acute and chronic characteristics of CAD. Propensity score matching (PSM) was used to further evaluate the robustness of the primary outcome. The ROC curve analysis results showed that the area under curve (AUC) values were 0.686 (95% CI 0.592-0.781, P<0.001) for NLR, 0.749 (95% CI 0.667-0.832, P<0.001) for CAR, and 0.571 (95% CI 0.455-0.687, P=0.232) for PLR. The Cox proportional hazard model showed that trends in NLR and PLR did not affect the risk of all-cause death (P=0.096 and P=0.544 for trend, respectively), but a higher CAR level corresponded to a higher risk of all-cause death (P<0.001 for trend). Similarly, The trends of NLR and PLR did not affect the risk of cardiovascular death and respiratory failure death, while a higher CAR level corresponded to a higher risk of cardiovascular death and respiratory failure death. The results of subgroup analyses and PSM were consistent with the total cohort. In patients with CAD complicated with COVID-19, a higher CAR level corresponded to a higher risk of all-cause death, cardiovascular death, and respiratory failure death, while trends in NLR and PLR did not.

Cardiogenic shock and chronic kidney disease: Dangerous liaisons

BackgroundChronic kidney disease (CKD) is one of the leading causes of death worldwide, closely interrelated with cardiovascular diseases, ultimately leading to the failure of both organs – the so-called “cardiorenal syndrome”. Despite this burden, data related to cardiogenic shock outcomes in CKD patients are scarce. MethodsFRENSHOCK (NCT02703038) was a prospective registry involving 772 patients with cardiogenic shock from 49 centres. One-year outcomes (rehospitalization, death, heart transplantation, ventricular assist device) were analysed according to history of CKD at admission and were adjusted on independent predictive factors. ResultsCKD was present in 164 of 771 patients (21.3%) with cardiogenic shock; these patients were older (72.7 vs. 63.9years) and had more comorbidities than those without CKD. CKD was associated with a higher rate of all-cause mortality at 1month (36.6% vs. 23.2%; hazard ratio 1.39, 95% confidence interval 1.01–1.9; P=0.04) and 1year (62.8% vs. 40.5%, hazard ratio 1.39, 95% confidence interval 1.09–1.77; P<0.01). Patients with CKD were less likely to be treated with norepinephrine/epinephrine or undergo invasive ventilation or receive mechanical circulatory support, but were more likely to receive renal replacement therapy (RRT). RRT was associated with a higher risk of all-cause death at 1month and 1year regardless of baseline CKD status. ConclusionsCardiogenic shock and CKD are frequent “cross-talking” conditions with limited therapeutic options, resulting in higher rates of death at 1month and 1year. RRT is a strong predictor of death, regardless of preexisting CKD. Multidisciplinary teams involving cardiac and kidney physicians are required to provide integrated care for patients with failure of both organs.

Association of antiseizure medications and adverse cardiovascular events: A global health federated network analysis.

A diagnosis of epilepsy has been associated with adverse cardiovascular events (CEs), but the extent to which antiseizure medications (ASMs) may contribute to this is not well understood. The aim of this study was to compare the risk of adverse CEs associated with ASM in patients with epilepsy (PWE). A retrospective case-control cohort study was conducted using TriNetX, a global health federated network of anonymized patient records. Patients older than 18 years, with a diagnosis of epilepsy (International Classification of Diseases, 10th Revision code G40) and a medication code of carbamazepine, lamotrigine, or valproate were compared. Patients with cardiovascular disease prior to the diagnosis of epilepsy were excluded. Cohorts were 1:1 propensity score matched (PSM) according to age, sex, ethnicity, hypertension, heart failure, atherosclerotic heart disease, atrial and cardiac arrythmias, diabetes, disorders of lipoprotein metabolism, obesity, schizophrenia and bipolar disorder, medications, and epilepsy classification. The primary outcome was a composite of adverse CEs (ischemic stroke, acute ischemic heart disease, and heart failure) at 10 years. Cox regression analyses were used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) following 1:1 PSM. Of 374 950 PWE included; three cohorts were established after PSM: (1) carbamazepine compared to lamotrigine, n = 4722, mean age 37.4 years; (2) valproate compared to lamotrigine, n = 5478, mean age 33.9 years; and (3) valproate compared to carbamazepine, n = 4544, mean age 37.0 years. Carbamazepine and valproate use were associated with significantly higher risk of composite cardiovascular outcome compared to lamotrigine (HR = 1.390, 95% CI = 1.160-1.665 and HR = 1.264, 95% CI = 1.050-1.521, respectively). Valproate was associated with a 10-year higher risk of all-cause death than carbamazepine (HR = 1.226, 95% CI = 1.017-1.478), but risk of other events was not significantly different. Carbamazepine and valproate were associated with increased CE risks compared to lamotrigine. Cardiovascular risk factor monitoring and careful follow-up should be considered for these patients.

Adverse Events and Clinical Correlates in Asian Patients with Atrial Fibrillation and Diabetes Mellitus: A Report from Asia Pacific Heart Rhythm Society Atrial Fibrillation Registry.

Aims. To evaluate the adverse events (and its clinical correlates) in a large prospective cohort of Asian patients with atrial fibrillation (AF) and diabetes mellitus (DM). Material and Methods. We recruited patients with atrial fibrillation (AF) from the Asia-Pacific Heart Rhythm Society (APHRS) AF Registry and included those for whom the diabetic mellitus (DM) status was known. We used Cox-regression analysis to assess the 1-year risk of all-cause death, thromboembolic events, acute coronary syndrome, heart failure and major bleeding. Results. Of 4058 patients (mean age 68.5 ± 11.8 years; 34.4% females) considered for this analysis, 999 (24.6%) had DM (age 71 ± 11 years, 36.4% females). Patients with DM had higher mean CHA2DS2-VASc (2.3 ± 1.6 vs. 4.0 ± 1.5, p < 0.001) and HAS-BLED (1.3 ± 1.0 vs. 1.7 ± 1.1, p < 0.001) risk scores and were less treated with rhythm control strategies compared to patients without DM (18.7% vs. 22.0%). After 1-year of follow-up, patients with DM had higher incidence of all-cause death (4.9% vs. 2.3%, p < 0.001), cardiovascular death (1.3% vs. 0.4%, p = 0.003), and major bleeding (1.8% vs. 0.9%, p = 0.002) compared to those without DM. On Cox regression analysis, adjusted for age, sex, heart failure, coronary and peripheral artery diseases and previous thromboembolic event, DM was independently associated with a higher risk of all-cause death (HR 1.48, 95% CI 1.00-2.19), cardiovascular death (HR 2.33, 95% CI 1.01-5.40), and major bleeding (HR 1.91, 95% 1.01-3.60). On interaction analysis, the impact of DM in determining the risk of all-cause death was greater in young than in older patients (p int = 0.010). Conclusions. Given the high rates of adverse outcomes in these Asian AF patients with DM, efforts to optimize the management approach of these high-risk patients in a holistic or integrated care approach are needed.

Prognostic value of transthoracic echocardiography score for the prognosis of continuous ambulatory peritoneal dialysis patients

BackgroundWe devoted ourselves to proving that the initial transthoracic echocardiography score (TTES) had predictive significance for patients with continuous ambulatory peritoneal dialysis (CAPD).MethodsIn this retrospective analysis, 274 CAPD patients who had PD therapy were recruited sequentially. TTE exams were performed three months following the start of PD therapy. All patients were divided into two groups based on the strength of their TTES levels. TTES’s predictive value for CAPD patients was then determined using LASSO regression and Cox regression.ResultsDuring a median of 52 months, 46 patients (16.8%) died from all causes, and 32 patients (11.7%) died from cardiovascular disease (CV). The TTES was computed as follows: 0.109 × aortic root diameter (ARD, mm) − 0.976 × LVEF (> 55%, yes or no) + 0.010 × left ventricular max index, (LVMI, g/m2) + 0.035 × E/e’ ratio. The higher TTES value (≥ 3.7) had a higher risk of all-cause death (hazard ratio, HR, 3.70, 95% confidence index, 95%CI, 1.45–9.46, P = 0.006) as well as CV mortality (HR, 2.74, 95%CI 1.15–19.17, P = 0.042). Moreover, the TTES had an attractive predictive efficiency for all-cause mortality (AUC = 0.762, 95%CI 0.645–0.849) and CV mortality (AUC = 0.746, 95%CI 0.640–0.852). The introduced nomogram, which was based on TTES and clinical variables, exhibited a high predictive value for all-cause and CV mortality in CAPD patients.ConclusionTTES is a pretty good predictor of clinical outcomes, and the introduced TTES-based nomogram yields an accurate prediction value for CAPD patients.

Corrected QT Interval and Outcomes of Dialysis Patients with Symptomatic Peripheral Artery Disease: A Prospective Cohort Study

Background: Peripheral artery disease (PAD) is common and associated with a higher risk of cardiovascular morbidity and mortality in dialysis patients. A longer corrected QT (QTc) interval has been associated with adverse cardiovascular events and mortality in the general population and patients with end-stage kidney disease. However, little evidence is available on the predictive value of QTc in dialysis patients with PAD. Methods: We conducted a prospective cohort study of 356 dialysis patients with symptomatic PAD undergoing endovascular therapy. We performed the resting 12-lead electrocardiogram (ECG) at baseline. Cox regression analyses were used to assess the association of QTc with all-cause mortality and major adverse cardiovascular events (MACEs), defined as non-fatal myocardial infarction, non-fatal stroke, and cardiovascular death. Results: The mean age was 67.3 ± 11.5 years; 41.6% of participants were women. The median QTc was 471 (interquartile ranges 448–491) milliseconds (ms). During a median follow-up of 2.2 years, 188 (52.8%) patients died, and MACEs occurred in 119 (33.4%) patients. In multivariable-adjusted models, patients in tertile 3 of QTc levels had a significantly greater risk of all-cause mortality (hazard ratio [HR] 2.41, 95% confidence intervals [CI] 1.58–3.69) and MACEs (HR 1.90, 95% CI 1.15–3.13) than those in tertile 1. Similarly, each 10-ms increase in the baseline QTc predicted a higher risk of all-cause death (HR 1.15, 95% CI 1.09–1.21) and MACEs (HR 1.15, 95% CI 1.07–1.23). Conclusions: QTc prolongation was independently associated with adverse outcomes among dialysis patients with symptomatic PAD.
