Surgery in patients with infective endocarditis and prognostic importance of patient frailty

PurposeSurgery is required in 20–50% of patients with infective endocarditis (IE). Frailty increases surgical risk; however, the prognostic implications of frailty in patients undergoing IE-related surgery remain poorly understood. We aimed to assess the association between frailty and all-cause mortality or rehospitalization after discharge (≥ 14 days).MethodsWe identified all IE patients who underwent surgery during admission (2010–2020) in Denmark. The Hospital Frailty Risk Score was used to categorize patients into two frailty risk groups, patients with low frailty scores (< 5 points) and frail patients (≥ 5 points). We analyzed time hospitalized after discharge and all-cause mortality from the date of surgery with a one-year follow-up. Statistical analyses utilized the Kaplan–Meier estimator, Aalen–Johansen estimator, and the Cox regression model.ResultsWe identified 1282 patients who underwent surgery during admission, of whom 967 (75.4%) had low frailty scores, and 315 (24.6%) were frail. Frail patients were characterized by advanced age, a lower proportion of males, and a higher burden of comorbidities. Frail patients were more hospitalized (> 14 days) in the first post-discharge year (19.1% vs.12.3%) compared to patients with low frailty scores. Additionally, frail patients had higher rates of all-cause mortality including in-hospital deaths (27% vs. 15%) and rehospitalizations (43.5% vs 26.1%) compared to patients with low frailty scores. This was also evident in the adjusted analysis (hazard ratio 1.36 [CI 95% 1.09–1.71]).ConclusionFrailty was associated with an ≈40% increased rate of rehospitalization (≥ 14 days) or death. Further studies are needed to assess the effectiveness of surgery with a focus on frailty to improve prognostic outcomes in these patients.

Clinical characteristics and outcomes of alcohol septal ablation in the era of transcatheter valve interventions.

The clinical efficacy and safety of alcohol septal ablation (ASA) for obstructive hypertrophic cardiomyopathy (HCM) have been well-established; however, less is known about outcomes in patients undergoing preemptive ASA before transcatheter mitral valve replacement (TMVR). The goal of this study is to characterize the procedural characteristics and examine the clinical outcomes of ASA in both HCM and pre-TMVR. This retrospective study compared procedural characteristics and outcomes in patient who underwent ASA for HCM and TMVR. In total, 137 patients were included, 86 in the HCM group and 51 in the TMVR group. The intraventricular septal thickness (mean 1.8 vs. 1.2 cm; p < 0.0001) and the pre-ASA LVOT gradient (73.6 vs. 33.8 mmHg; p ≤ 0.001) were higher in the HCM group vs the TMVR group. The mean volume of ethanol injected was higher (mean 2.4 vs. 1.7 cc; p < 0.0001). The average neo-left ventricular outflow tract area increased significantly after ASA in the patients undergoing TMVR (99.2 ± 83.37 mm2 vs. 196.5 ± 114.55 mm2; p = <0.0001). The HCM group had a greater reduction in the LVOT gradient after ASA vs the TMVR group (49.3 vs. 18 mmHg; p = 0.0040). The primary composite endpoint was higher in the TMVR group versus the HCM group (50.9% vs. 25.6%; p = 0.0404) and had a higher incidence of new permanent pacemaker (PPM) (25.5% vs. 18.6%; p = 0.3402). The TMVR group had a higher rate of all-cause mortality (9.8% vs. 1.2%; p = 0.0268). Preemptive ASA before TMVR was performed in patients with higher degree of clinical comorbidities, and correspondingly is associated with worse short-term clinical outcomes in comparison to ASA for HCM patients. ASA before TMVR enabled percutaneous mitral interventions in a small but significant minority of patients that would have otherwise been excluded. The degree of LVOT and neoLVOT area increase is significant and predictable.

Gender differences in the relationship between serum uric acid and the long-term prognosis in heart failure: a nationwide study

BackgroundSerum uric acid (SUA) is an important pathogenetic and prognostic factor for heart failure (HF). Gender differences are apparent in HF. Furthermore, gender differences also exist in the association between SUA and prognosis in various cardiovascular diseases. However, the gender difference for SUA in the prediction of long-term prognosis in HF is still ambiguous.MethodsA total of 1593 HF patients (897 men, 696 women) from the National Health and Nutrition Examination Survey (NHANES) 1999–2018 cycle were enrolled in our final analysis. Participants were categorized according to gender-specific SUA tertile. We assessed the association between SUA and long-term prognosis of HF patients, defined as all-cause mortality and cardiovascular mortality, in different genders via Kaplan–Meier curve analysis, Cox proportional hazard model, and Fine-Gray competing risk model. The restricted cubic spline (RCS) was performed to investigate the dose-response relationship between SUA and outcomes.ResultsGender differences exist in demographic characteristics, clinical parameters, laboratory tests, and medication of HF patients. After a median follow-up of 127 months (95% CI 120–134 months), there were 853 all-cause deaths (493 events in men, 360 events in women) and 361 cardiovascular deaths (206 events in men, 155 events in women). Kaplan-Meier analysis showed that SUA had gender difference in the prediction of cardiovascular mortality (Log-rank p < 0.001, for male, Log-rank p = 0.150, for female), but not in all-cause mortality. Multivariate Cox regression analysis revealed that elevated SUA levels were associated with higher all-cause mortality and cardiovascular mortality in men (HR 1.11, 95% CI 1.05-1.18, p < 0.001, for all-cause death; HR 1.18, 95% CI 1.09-1.28, p < 0.001, for cardiovascular death), but not in women (HR 1.05, 95% CI 0.98-1.12, p = 0.186, for all-cause death; HR 1.01, 95% CI 0.91-1.12, p = 0.902, for cardiovascular death). Even using non-cardiovascular death as a competitive risk, adjusted Fine-Gray model also illustrated that SUA was an independent predictor of cardiovascular death in men (SHR 1.17, 95% CI 1.08-1.27, p < 0.001), but not in women (SHR 0.98, 95% CI 0.87 − 1.10, p = 0.690).ConclusionsGender differences in the association between SUA and long-term prognosis of HF existed. SUA was an independent prognostic predictor for long-term outcomes of HF in men, but not in women.

Handgrip strength and mortality in a cohort of kidney failure patients: Comparative analysis of different normalization methods

ObjectivesReduced handgrip strength (HGS) is associated with adverse clinical outcomes. We analyzed and compared associations of HGS with mortality risk in dialysis patients, using different normalization methods of HGS. MethodsHGS and clinical and laboratory parameters were measured in a cohort of 446 incident dialysis patients (median age 56 y, 62% men). The area under the receiver operating characteristic curve (AUROC) was used to compare different normalization methods of HGS as predictors of mortality: absolute HGS in kilograms; HGS normalized to height, weight, or body mass index; and HGS of a reference population of sex-matched controls (percentage of the mean HGS value [HGS%]). Multivariate linear regression analysis was used to assess HGS predictors. Competing risk regression analysis was used to evaluate 5-year all-cause mortality risk. Differences in survival time between HGS% tertiles were quantitated by analyzing the restricted mean survival time. ResultsThe AUROC for HGS% was higher than the AUROCs for absolute or normalized HGS values. Compared with the high HGS% tertile, low HGS% (subdistribution hazard ratio [sHR] = 2.36; 95% CI, 1.19–3.70) and middle HGS% (sHR = 1.79; 95% CI, 1.12–2.74) tertiles were independently associated with higher all-cause mortality and those with high HGS% tertile survived on average 7.95 mo (95% CI, 3.61–12.28) and 18.99 mo (95% CI, 14.42–23.57) longer compared with middle and low HGS% tertile, respectively. ConclusionsHGS% was a strong predictor of all-cause mortality risk in incident dialysis patients and a better discriminator of survival than absolute HGS or HGS normalized to body size dimensions.

Evaluation of the Lifetime Benefits of Metformin and SGLT2 Inhibitors in Type 2 Diabetes Mellitus Patients with Cardiovascular Disease: A Systematic Review and Two-Stage Meta-Analysis.

Metformin and sodium-glucose cotransporter-2 (SGLT2) inhibitors have demonstrated cardiovascular benefits but their comparative effects on mortality in type 2 diabetes mellitus (T2DM) patients with cardiovascular disease (CVD) are unknown. Hence, we evaluated and compared lifetime benefits arising from metformin or SGLT2 inhibitors in T2DM patients with CVD. Studies published in the PubMed, EMBASE and CENTRAL databases before 28 October 2023 were retrieved. Treatment effects of metformin against US FDA-approved SGLT2 inhibitors in T2DM patients with CVD were evaluated and lifetime gains in event-free survival were estimated from our primary endpoints of all-cause and cardiovascular mortality. Risk ratios were derived to assess their impact on secondary outcomes such as major adverse cardiovascular events and hospitalizations for heart failure. Overall, 14 studies were included. Five studies published Kaplan-Meier curves for the primary outcome of all-cause mortality. Individual participant data were reconstructed from these Kaplan-Meier curves, from which we conducted our two-stage meta-analysis. Participants receiving metformin and SGLT2 inhibitors experienced a reduction in the risk for all-cause mortality as compared with those not taking metformin and placebo. However, participants receiving SGLT2 inhibitors had a higher all-cause mortality (hazard ratio 1.308, 95% confidence interval 1.103-1.550) versus metformin. Treatment with metformin was estimated to offer an additional 23.26months of survival free from all-cause mortality versus 23.04months with SGLT2 inhibitors. In patients with T2DM and CVD, metformin and SGLT2 inhibitors were associated with substantially lower all-cause mortality rates and slightly longer life expectancies than in patients without. Metformin presented an advantage over SGLT2 inhibitors in reducing all-cause mortality.

Rural-urban Differences in Long-term Mortality and Readmission Following COVID-19 Hospitalization, 2020 to 2023.

We compared long-term mortality and readmission rates after COVID-19 hospitalization based on rural-urban status and assessed the impact of COVID-19 vaccination introduction on clinical outcomes by rurality. The study comprised adults hospitalized for COVID-19 at 17 hospitals in 4 US states between March 2020 and July 2022, followed until May 2023. The main analysis included all patients, whereas a sensitivity analysis focused on residents from 4 states containing 17 hospitals. Additional analyses compared the pre- and postvaccination periods. The main analysis involved 9325 COVID-19 hospitalized patients: 31% were from 187 rural counties in 31 states; 69% from 234 urban counties in 44 states; the mean age was 65 years (rural, 66 years; urban, 64 years); 3894 women (rural, 41%; urban, 42%); 8007 Whites (rural, 87%; urban, 83%); 1738 deaths (rural, 21%; urban, 17%); and 2729 readmissions (rural, 30%; urban, 29%). During a median follow-up of 602 days, rural residence was associated with a 22% higher all-cause mortality (log-rank, P < .001; hazard ratio, 1.22; 95% confidence interval, 1.10-1.34, P < .001), and a trend toward a higher readmission rate (log-rank, P = .038; hazard ratio, 1.06; 95% confidence interval, .98-1.15; P = .130). The results remained consistent in the sensitivity analysis and in both pre- and postvaccination time periods. Patients from rural counties experienced higher mortality and tended to be readmitted more frequently following COVID-19 hospitalization over the long term compared with those from urban counties, a difference that remained even after the introduction of COVID-19 vaccines.

Prognosis of patients with coexisting obesity and malnutrition after ischemic stroke: A cohort study

BackgroundThe double burden of malnutrition, defined as the coexistence of obesity and malnutrition, is an increasing global health concern and is unclear in patients after ischemic stroke. The current study explored the combined impacts of obesity and malnutrition on patients with ischemic stroke. MethodsWe conducted a single-center prospective cohort study with patients with ischemic stroke enrolled in Minhang Hospital in China between January 2018 and December 2022. Patients were stratified into four categories based on their obesity (defined by body mass index) and nutritional status (classified according to the Controlling Nutritional Status score): (1) nourished nonobese; (2) malnourished nonobese; (3) nourished obese, and (4) malnourished obese. The primary end points were poor outcomes and all-cause mortality at 3 months. ResultsA total of 3160 participants with ischemic stroke were included in our study, of which 64.7% were male and the mean age was 69 years. Over 50% of patients were malnourished. At 3-month follow-up, the malnourished nonobese had the worst outcomes (34.4%), followed by the malnourished obese (33.2%), nourished nonobese (25.1%), and nourished obese (21.8%; P<0.001). In multivariable analyses, with nourished nonobese group as the reference, the malnourished nonobese group displayed poorer outcomes (odds ratio [OR], 1.395 [95% CI, 1.169–1.664]; P<0.001) and higher all-cause mortality (OR, 1.541 [95% CI, 1.054-2.253], P=0.026), but only a nonsignificant increase in poor prognosis rate (33.2% vs. 25.1%, P=0.102) and mortality (4.2% vs. 3.6%, P=0.902) were observed in the malnourished obese group. ConclusionA high prevalence of malnutrition is observed in the large population suffering from ischemic attack, even in the obese. Malnourished patients have the worst prognosis particularly in those with severe nutritional status regardless of obesity, while the best functional outcomes and the lowest mortality are demonstrated in nourished obese participants.

Acute Coronary Syndrome Revascularization Strategies With Multivessel Coronary Artery Disease

In acute coronary syndromes (ACS), revascularization is the standard of care. However, trials comparing contemporary coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) are limited. Optimal revascularization in patients with multi-vessel coronary artery disease (MV-CAD) presenting with ACS is unclear. This is a multi-centred, retrospective observational study from a large, hospital system in the United States. We abstracted data on patients with MV-CAD and ACS from 2018 to 2022 who underwent revascularization with PCI, CABG or medically managed (MM). We evaluated multivariate statistics comparing categorical variables and outcomes, including all-cause mortality (ACM) and myocardial infarction (MI) at 1 year. All logistic and Cox proportional-hazard models were balanced using inverse probability treatment weights accounting for age and sex. There were 295 CABG patients [median age 66 (IQR 59.7, 73.1); 73% male], 1,559 PCI patients [median age 68.3 (IQR 60, 76.6); 69.1% male], and 307 MM patients [median age 70 (60.9, 77.1) 74% male]. Patients revascularized with PCI had higher ACM at 1 year [14.1% vs. 5.1%; HR 2.4, CI (1.5, 3.8), p<0.001] and similar mortality to MM (13.4%). CABG also demonstrated reduced 1 year MI rate compared to PCI (1.7% vs 3.9%; HR 0.36, CI 0.21, 0.61, p=<0.001), with similar 1 year rate of MI to MM (3.9%). In conclusion, CABG, compared to PCI and MM, is associated with lower mortality, and repeat ACS events at 1 year in patients with ACS and MV-CAD.

Long-term clinical outcomes in elderly patients with chronic total occlusion and type 2 diabetes: the impact of coronary collateralization following successful recanalization

Background and purpose: Chronic total occlusion (CTO) lesions commonly affect elderly patients, especially those with type 2 diabetes mellitus (T2DM), often associated with coronary collaterals (CC). However, it remains unclear whether CC influences the prognosis of CTO. This retrospective single-center study aimed to evaluate the prognostic relevance of CC in elderly patients with T2DM after successful revascularization for CTO. Methods: We analyzed data from 416 patients diagnosed with CTO who underwent successful revascularization between January 2013 and January 2017. Patients were categorized into two groups: the Non-T2DM group and T2DM group. Subgroup analyses were performed based on the status of CC. The primary outcome was the occurrence of major adverse cardiac events (MACE) during the follow-up period, with the secondary outcomes including all-cause mortality, cardiac death, and repeat revascularization. Results: CC did not significantly impact clinical endpoints in the overall elderly patient population. However, we observed a lower incidence of MACE, cardiac death, all-cause mortality, and repeat revascularization in the Non-T2DM group compared to the T2DM group. In patients without T2DM, poor-CC was associated with higher rates of all-cause mortality (9% vs. 18%, P = 0.041), an increased risk of cardiac death (5% vs. 12%, P = 0.042), and a greater incidence of MACE (15% vs. 28%, P = 0.031), whereas no such associations were observed in T2DM patients. Furthermore, in multivariate Cox analysis, T2DM emerged as an independent factor influencing the time to MACE (adjusted hazard ratio [HR]:1.847, 95% confidence interval [95% CI]: 1.215–2.810, P = 0.004) and repeat revascularization (adjusted HR: 2.093, 95% CI: 1.310–3.344, P = 0.002) in elderly CTO patients, rather than coronary collateralization. Notably, regardless of the quality of CC, elderly patients with T2DM exhibited a poorer prognosis. Conclusions: Elderly patients without T2DM derived greater long-term survival benefits from successful revascularization of CTO compared to those with T2DM. Additionally, good collateralization was associated with a decreased risk of adverse clinical outcomes specifically in Non-T2DM patients.

Carbapenem-Resistant Pseudomonas aeruginosa Infection and Mixed Infections Are Risk Factors for Poor Outcome After Lung Transplant.

In this study, we analyzed the effects of carbapenem-resistant Pseudomonas aeruginosa infection and mixed infection on the perioperative prognosis of lung transplant recipients and studied statistics on antibiotic resistance in P aeruginosa. This was a retrospective casecontrol study. We collected data on lung transplant recipients with combined lower respiratory tract P aeruginosa infection within 48 hours after lung transplant at the China-Japan Friendship Hospital from August 2018 to April 2022. We grouped recipients according to P aeruginosa resistance to carbapenem antibiotics and summarized the clinical characteristics of carbapenem-resistant P aeruginosa infection. We analyzed the effects of carbapenemresistant P aeruginosa infection and mixed infections on all-cause mortality 30 days after lung transplant by Cox regression. We used the Kaplan-Meier method to plot survival curves. Patients in the carbapenem-resistant P aeruginosa group had a higher all-cause mortality rate than those in the carbapenem-sensitive P aeruginosa group at both 7 days (6 patients [22.3%] vs 2 patients [4.5%]; P = .022) and 30 days (12 patients [44.4%] vs 7 patients [15.9%]; P = .003) after lung transplant. In multivariate analysis, both carbapenemresistant P aeruginosa infection and P aeruginosa combined with bacterial infection were independent risk factors for death 30 days after transplant in lung transplant recipients (P < .05). In subgroup analysis, carbapenem-resistant P aeruginosa combined with bacterial infection increased the risk of death 30 days after transplant in lung transplant recipients compared with carbapenem-sensitive P aeruginosa combined with bacterial infection (12 patients [60%] vs 6 patients [19.4%]; P < .001). Combined lower respiratory tract carbapenem-resistant P aeruginosa infection and P aeruginosa combined with bacterial infection early after lung transplant increased the risk of 30-day mortality after lung transplant.

Abstract 841: Fine particulate matter exposure during breast cancer treatment among older women associated with increased mortality

Abstract Background: Fine Particulate Matter (PM2.5) is associated with higher mortality among people with chronic conditions. Breast cancer (BC) survivors may be particularly vulnerable during cancer treatment. We assessed the association between PM2.5 during 9-months following BC diagnosis and all-cause and BC-mortality using policy relevant PM2.5 cut-offs. Methods: Using SEER-Medicare linked with a high-resolution model-based PM2.5 by residential zipcode (2007-2016), we assembled a cohort of women ≥66 years with incident stage I-IV BC. We assessed PM2.5 exposure, categorized as &amp;lt;8 µg/m3 (low), 8-12 µg/m3 (moderate) and &amp;gt;12 µg/m3 (high—above air quality standard), and types of cancer treatments (surgery [SX], chemotherapy [CTX], radiation therapy [RTX]) during a 9-month landmark period. We identified all-cause and BC death within 5 years of diagnosis. We fit multivariable Cox proportional hazard models to assess associations with PM2.5 exposure adjusting for individual-level characteristics (demographics, tumor characteristics, comorbidities), neighborhood SES, SEER state, and long-term PM2.5 exposure. We also evaluated the association between PM2.5 exposure and mortality by treatment types (SX, SX + RTX, SX + CTX, SX + RTX + CTX, and RTX and/or CTX). We used multiple imputation to account for missing variables (race, ER status, HER2 status, grade). Results: Among 72,798 women (mean age 75 years, 83% white, 56% stage I, 32% II, 9.2% III, 2.9% IV), 41%, 32%, 13%, 8.4%, and 5.1% received SX + RTX, SX only, SX + Chemo + RTX, SX + Chemo, and CTX and/or RTX. The mean PM2.5 level was 8.8 µg/m3 [36%, 52% and 11% were exposed to &amp;lt;8, 8-12, and &amp;gt;12, respectively]. We observed 12,163 all-cause and 4,729 BC deaths during follow-up. Compared to those exposed to low levels, higher levels of PM2.5 exposure were associated with increased all-cause mortality for both moderate PM2.5 [HR 1.03 (95%CI:1.00-1.05)] and high PM2.5 [HR 1.09 (95%CI: 1.06-1.14)] but not BC-specific mortality. Among treatment subgroups, PM2.5 was associated with higher all-cause mortality in SX+RTX for moderate [HR 1.24 (95%CI:1.18-1.32)] and high PM2.5 [HR 1.36 (95%CI: 1.25-1.48)] and SX+RTX+CTX for high PM2.5 [HR 1.33 (95%CI: 1.17-1.51)]. There were no association between moderate/high PM2.5 with all-cause mortality in SX only and SX+CTX. Among the SX+RTX subgroup, BC-specific mortality was elevated for both moderate [HR 1.50 (95%CI:1.35-1.66)] and high PM2.5 [HR 1.81 (95%CI: 1.55-2.12)]. Conclusion: Even below EPA regulatory thresholds (PM2.5 &amp;lt;12 µg/m3), we observed increased risk of death in BC survivors who had high PM2.5 exposure during treatment period. The elevated mortality primarily occurred among women who received RTX and was present for all-cause and BC-specific mortality. The potential interaction between RTX and PM2.5 exposure, even after adjusting for tumor subtype and stage, warrants further evaluation.

Subtype-Specific Association of Mitochondrial DNA Copy Number With Poststroke/TIA Outcomes in 10 241 Patients in China.

Mitochondrial DNA copy number (mtDNA-CN) is associated with the severity and mortality in patients with stroke, but the associations in different stroke subtypes remain unexplored. We conducted an observational prospective cohort analysis on patients with ischemic stroke or transient ischemic attack enrolled in the Third China National Stroke Registry. We applied logistic models to assess the association of mtDNA-CN with functional outcome (modified Rankin Scale score, 3-6 versus 0-2) and Cox proportional hazard models to assess the association with stroke recurrence (treating mortality as a competing risk) and mortality during a 12-month follow-up, adjusting for sex, age, physical activity, National Institutes of Health Stroke Scale at admission, history of stroke and peripheral artery disease, small artery occlusion, and interleukin-6. Subgroup analyses stratified by age and stroke subtypes were conducted. The Third China National Stroke Registry enrolled 15 166 patients, of which 10 241 with whole-genome sequencing data were retained (mean age, 62.2 [SD, 11.2] years; 68.8% men). The associations between mtDNA-CN and poststroke/transient ischemic attack outcomes were specific to patients aged ≤65 years, with lower mtDNA-CN significantly associated with stroke recurrence in 12 months (subdistribution hazard ratio, 1.15 per SD lower mtDNA-CN [95% CI, 1.04-1.27]; P=5.2×10-3) and higher all-cause mortality in 3 months (hazard ratio, 2.19 [95% CI, 1.41-3.39]; P=5.0×10-4). Across subtypes, the associations of mtDNA-CN with stroke recurrence were specific to stroke of undetermined cause (subdistribution hazard ratio, 1.28 [95% CI, 1.11-1.48]; P=6.6×10-4). In particular, lower mtDNA-CN was associated with poorer functional outcomes in stroke of undetermined cause patients diagnosed with embolic stroke of undetermined source (odds ratio, 1.53 [95% CI, 1.20-1.94]; P=5.4×10-4), which remained significant after excluding patients with recurrent stroke (odds ratio, 1.49 [95% CI, 1.14-1.94]; P=3.0×10-3). Lower mtDNA-CN is associated with higher stroke recurrence rate and all-cause mortality, as well as poorer functional outcome at follow-up, among stroke of undetermined cause, embolic stroke of undetermined source, and younger patients.

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.

Mitigating disparity?: Treatment patterns, survival, and recurrence rates by race, ethnicity, and hospital site across a large urban health system

ObjectiveNational data have shown worse endometrial cancer (EC) outcomes among racial and ethnic minorities. We aimed to analyze EC patient outcomes within a large urban academic health system, with a focus on patterns of care and recurrence rates. MethodsThis was a retrospective chart review of EC patients at three system hospitals from 1/1/07–12/31/17. Demographic and clinical factors, including time from EMB to surgery, rate of chemotherapy completion, persistent or recurrent disease, and palliative care referrals were extracted. Descriptive statistics and survival curves were generated. Analysis was done using SAS version 9.4. ResultsBlack patients had lower overall survival compared to all others on univariate analysis only (p < 0.0001). Hospital site was associated with OS, with the academic anchor and satellite 1 having higher rates of all-cause mortality compared to satellite 2 (HR 4.68 academic anchor, 95 % CI 1.72–12.76, HR 5.36 satellite 1, 95 % CI 1.85–15.52). Time from EMB to surgery and rates of persistent disease following primary treatment were higher in Black patients. After adjusting for stage and grade, chemotherapy completion rate was significantly associated with race. Palliative care was utilized more for Black than White patients after adjusting for stage and grade (p = 0.005). ConclusionsRacial disparities in EC are caused by a complex web of interconnected factors that ultimately lead to worse outcomes in Black women. While precision medicine has helped to close the gap, social determinants of health should be addressed, and models focusing on the complex interactions between biologic, genetic, and social factors should be utilized.

Childhood sexual abuse and suicide attempts in patients with substance use disorders: The mediating role of emotion dysregulation

BackgroundSuicide attempts (SA) are a public health concern because of increasing prevalence and clinical implications. Childhood trauma (CT) and emotion dysregulation (ED) have been proposed as predictors of SA, but few data are available in patients with Substance Use Disorder (SUD). ObjectiveOur study aims to investigate the association of sociodemographic/clinical variables, CT typologies, and ED features with SA in SUD patients. Participants and settingSubjects with SUD were screened in an outpatient setting. The final sample consisted of 226 patients, subdivided according to the presence of lifetime SA (SUD, n = 163 vs. SUD-SA, n = 63). MethodsParticipants were compared for sociodemographic and clinical information. CT and ED were assessed through the Childhood Trauma Questionnaire - Short Form (CTQ-SF) and the Difficulties in Emotion Regulation Scale (DERS), respectively. We performed a mediation analysis to test the effect of CT and ED on SA. ResultsPatients with a history of SA (27.9 %) displayed more psychiatric comorbidities (p = 0.002) and hospitalizations (p < 0.001), higher scores at CTQ-SF sexual abuse (p < 0.001) and DERS ‘impulse’ (p = 0.002), ‘goals’, ‘non-acceptance’, ‘strategies’ (p < 0.001) subscales. The relationship between CTQ-SF sexual abuse and SA was significantly mediated by DERS ‘strategies’ (p = 0.04; bootstrapped 95 % LLCI-ULCI = 0.004–0.024). ConclusionsCT and different dimensions of ED were associated with SA in SUD patients. In our sample, the effects of childhood sexual abuse on SA were mediated by limited access to emotion regulation strategies. SUD patients are burdened with higher all-cause mortality, and CT and lifetime SA can worsen clinical outcomes. Clarifying the reciprocal interactions of psychopathological dimensions may help deliver targeted interventions and reduce suicide risk in specific populations.

The Intersection of Atrial Fibrillation and Coronary Artery Disease in Middle Eastern Patients. Analysis from the Jordan Atrial Fibrillation Study.

There is a scarcity of clinical studies which evaluate the association of atrial fibrillation (AF) and coronary artery disease (CAD) in the Middle East. The aim of this study was to evaluate the impact of CAD on baseline clinical profiles and one-year outcomes in a Middle Eastern cohort with AF. Consecutive AF patients evaluated in 29 hospitals and cardiology clinics were enrolled in the Jordan AF Study (May 2019-December 2020). Clinical and echocardiographic features, use of medications and one-year outcomes in patients with AF/CAD were compared to AF/no CAD patients. Of 2020 AF patients enrolled, 216 (10.7%) had CAD. Patients with AF/CAD were more likely to be men and had significantly higher prevalence of hypertension, diabetes, dyslipidemia, heart failure and chronic kidney disease compared to the AF/no CAD patients. They also had lower mean left ventricular ejection fraction and larger left atrial size. Mean CHA2DS2 VASc and HAS-BLED scores were higher in AF/CAD patients than those with AF/no CAD (4.3 ± 1.7 vs. 3.6 ± 1.8, p < 0.0001) and (2.0 ± 1.1 vs. 1.6 ± 1.1, p < 0.0001), respectively. Oral anticoagulant agents were used in similar rates in the two groups (83.8% vs. 82.9%, p = 0.81), but more patients with AF/CAD were prescribed additional antiplatelet agents compared to patients with AF/no CAD (73.7% vs. 41.5%, p < 0.0001). At one year, AF/CAD patients, compared to AF/no CAD patients had significantly higher hospitalization rate (39.4% vs. 29.2%, p = 0.003), more acute coronary syndrome and coronary revascularization (6.9% vs. 2.4%, p = 0.004), and higher all-cause mortality (18.5% vs. 10.9%, p = 0.002). In this cohort of Middle Eastern patients with AF, one in 10 patients had CAD. The coexistence of AF and CAD was associated with a worse baseline clinical profile and one-year outcomes. Clinical study registration: the study is registered on clinicaltrials.gov (unique identifier number NCT03917992).

Mortality in patients admitted to hospital with heart failure in China: a nationwide Cardiovascular Association Database-Heart Failure Centre Registry cohort study

China has the largest burden of heart failure worldwide. However, large-scale studies on heart failure mortality are scarce. We aimed to investigate mortality and identify risk factors for mortality among patients with heart failure in China. This prospective cohort study used data from the China Cardiovascular Association (CCA) Database-Heart Failure Centre Registry, which were linked to the National Mortality Registration Information Management System by the Chinese Centre for Disease Control and Prevention. We included patients enrolled from Jan 1, 2017, to Dec 31, 2021, across 572 CCA Database-Heart Failure Centre certified hospitals in 31 provinces of mainland China. Eligible patients were aged 18 years or older (younger than 100 years) with a principal discharge diagnosis of heart failure based on Chinese heart failure guidelines. All-cause mortality at 30 days, 1 year, and 3 years for patients with heart failure were calculated and the causes of death were recorded. Multivariable analysis was used to analyse factors associated with all-cause mortality and cardiovascular mortality. This study was registered with the Chinese Clinical Trial Registry, ChiCTR2200066305. Of the 327 477 patients in the registry, 230 637 eligible adults with heart failure were included in our analyses. Participant mean age was 69·3 years (SD 13·2), 94 693 (41·1%) participants were female, and 135 944 (58·9%) were male. The median follow-up time was 531 days (IQR 251-883). Post-discharge all-cause mortality of patients with heart failure at 30 days was 2·4% (95% CI 2·3-2·5), at 1 year was 13·7% (13·5-13·9), and at 3 years was 28·2% (27·7-28·6). Cardiovascular death accounted for 32 906 (71·5%) of 46 006 all-cause deaths. Patients with heart failure with reduced ejection fraction had the highest all-cause mortality. A lower guideline adherence score was independently associated with the increase of all-cause and cardiovascular mortality. In China, mortality for patients with heart failure is still high, especially in patients with reduced ejection fraction. Our findings suggest that guideline-directed medical therapy needs to be improved.

Incidence and Predictors of Worsening Renal Function in Edoxaban-Treated Atrial Fibrillation Patients Within ETNA-AF-Europe Registry

BackgroundManaging patients with atrial fibrillation (AF) and worsening renal function (WRF) remains a clinical challenge due to the need of dose adjustment of non-vitamin K antagonist oral anticoagulants. ObjectivesTo determine the incidence of WRF in patients with AF treated with edoxaban, the association of WRF with clinical outcomes, and predictors of WRF and clinical outcomes in these patients. MethodsThis is a subanalysis of the Edoxaban Treatment in routiNe clinical prActice for patients with non-valvular Atrial Fibrillation in Europe study (NCT02944019), an observational study of edoxaban-treated patients with AF. WRF was defined as a ≥25% reduction in creatinine clearance between baseline and 2 years. ResultsOf the 9,054 patients included (69% of the total 13,133 enrolled), most did not experience WRF (90.3%) during the first 2 years of follow-up. WRF occurred in 9.7% of patients. Patients with WRF had significantly higher rates of all-cause death (3.88%/y vs 1.88%/y; P < 0.0001), cardiovascular death (2.09%/y vs 0.92%/y; P < 0.0001), and major bleeding (1.51%/y vs 0.98%/y; P = 0.0463) compared with those without WRF. Rates of intracranial hemorrhage (0.18%/y vs 0.18%/y) and of any stroke/systemic embolic events were low (0.90%/y vs 0.69%/y; P = 0.3161) in both subgroups. The strongest predictors of WRF were a high CHA2DS2-VASc score, high baseline creatinine clearance, low body weight, and older age. Most predictors of WRF were also predictors of clinical outcomes. ConclusionsWRF occurred in approximately 10% of edoxaban-treated AF patients. Rates of death and major bleeding were significantly higher in patients with WRF than without. Stroke events were low in both subgroups.

The role of remnant cholesterol in patients with ST-segment elevation myocardial infarction.

Remnant cholesterol (RC) is the cholesterol content within triglyceride-rich lipoproteins. It promotes atherosclerotic cardiovascular disease beyond LDL cholesterol (LDL-C). The prognostic role of RC in patients with ST-segment elevation myocardial infarction (STEMI) is unknown. We aimed to estimate RC-related risk beyond LDL-C in patients with STEMI. A total of 6602 consecutive patients with STEMI treated with primary percutaneous coronary intervention (PCI) from 1999 to 2016 were included. Remnant cholesterol was calculated as total cholesterol minus LDL-C minus HDL cholesterol. Adjusted Cox models were used to estimate the association between continuous RC levels and all-cause mortality, cardiovascular death, ischaemic stroke, and recurrent myocardial infarction (MI) at long-term (median follow-up of 6.0 years). Besides, discordance analyses were applied to examine the risk of the discordantly high RC (RC percentile rank minus LDL-C percentile rank > 10 units) compared with the discordantly low RC (LDL-C percentile rank minus RC percentile rank > 10 units). The concordance was defined as the percentile rank difference between RC and LDL-C ≤ 10 units. The median age of patients was 63 years [interquartile range (IQR) 54-72] and 74.8% were men. There were 2441, 1651, and 2510 patients in the discordantly low RC group, concordant group, and discordantly high RC group, respectively. All outcomes in the discordantly high RC group were higher than the other groups, and the event rate of all-cause mortality in this group was 31.87%. In the unadjusted analysis, the discordantly high RC was associated with increased all-cause mortality [hazard ratio (HR) 1.82, 95% confidence interval (CI) 1.63-2.04] and increased cardiovascular death (HR 1.79, 95% CI 1.55-2.06) compared with the discordantly low RC. In an adjusted model, RC was associated with higher all-cause mortality (HR 1.14, 95% CI 1.07-1.22). The discordantly high RC was associated with increased all-cause mortality (adjusted HR 1.55, 95% CI 1.37-1.75) and increased cardiovascular death (adjusted HR 1.47, 95% CI 1.25-1.72) compared with the discordantly low RC. There were no associations between RC and ischaemic stroke or recurrent MI. In patients with STEMI treated with primary PCI, elevated RC levels beyond LDL-C and discordantly high RC were independently associated with increased all-cause mortality.

Association of secondhand smoke exposure with all-cause mortality and cardiovascular death in patients with hypertension: Insights from NHANES

Background and aimThe impact of environmental chemical exposure on blood pressure (BP) is well-established. However, the relationship between secondhand smoke exposure (SHSE) and mortality in hypertensive patients in the general population remains unclear. Methods and resultsThis cohort study included US adults in the National Health and Nutrition Examination Survey from 2007 to 2018. All-cause mortality and cause-specific mortality outcomes were determined by associating them with the National Death Index records. Cox proportional risk models were used to estimate hazard ratios (HRs) for all-cause mortality and cardiovascular disease (CVD) mortality, and 95% confidence intervals (CIs) for SHSE. The cohort included 10,760 adult participants. The mean serum cotinine level was 0.024 ng/mL. During a mean follow-up period of 76.9 months, there were 1729 deaths, including 469 cardiovascular disease deaths recorded. After adjusting for lifestyle factors, BMI, hypertension duration, medication use, and chronic disease presence, the highest SHSE was significantly associated with higher all-cause and CVD mortality. ConclusionsThis study demonstrates that higher SHSE is significantly associated with higher all-cause mortality and CVD mortality. Further research is necessary to elucidate the underlying mechanisms.
