Abstract
INTRODUCTION The concurrent data on sex disparities in VT management and outcomes have remained unclear. Therefore, our objective was to determine the impact of sex on ventricular tachycardia (VT) management and outcomes in patients admitted with VT, dervied from the US National Inpatient Sample database (NIS). METHODS We used data from the US NIS to identify hospitalized adult patients who were admitted with VT between 2016 and 2018. Regression analysis was conducted to evaluate the impact of sex on VT management, in-hospital mortality, complications, length of stay, and hospitalization costs. RESULTS Of the database, a total of 146 070 patients, who were primarily hospitalized for VT, were approximated. Among these, women comprised 25.5%; they were significantly younger and had fewer comorbidities. Of procedural aspects, women were less likely to receive an angiogram, mechanical support, implantable cardioverter-defibrillator implantation, and VT ablation compared to men. Notably, women were associated with higher do-not-resuscitate rates and in-hospital cardiac arrests than men. No differences in in-hospital mortality and cardiogenic shock were observed between men and women (p > .05). Length of stay was significantly longer for women, while no differences in hospital costs were observed in both sexes. CONCLUSION Significant sex disparities in management and outcomes were observed in admitted patients with VT. Our results reflect the need for further studies to explore factors causing such diversities.

Prognostic Importance of Atrial Fibrillation and Anticoagulation in Alcoholic Versus Dilated Cardiomyopathy. Alcohol Alcohol 2023; 58:159-163. [PMID: 36426877 DOI: 10.1093/alcalc/agac060] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2022] [Revised: 09/05/2022] [Accepted: 10/23/2022] [Indexed: 11/27/2022] Open
Abstract
AIMS Limited data exist to describe the prognostic impact of atrial fibrillation (AF) and oral anticoagulation on patients with alcoholic cardiomyopathy (ACM) compared with dilated cardiomyopathy (DCM) and were investigated in this study. METHODS Using Danish nationwide registries, a cohort analysis was conducted to assess the prognostic differences for patients with a first diagnosis of ACM versus DCM with and without AF 1994-2018 (followed until end 2019). Our study also assessed differences in mortality following initiation of anticoagulation in both populations. RESULTS Totally, 1237 patients with ACM (33% with AF) and 17,211 individuals with DCM (33% with AF) were included. Those with ACM were more often men (89 versus 71%) and younger than patients with DCM (mean age 56 versus 64 years). Cumulative 5-year mortality was greater among patients with ACM, compared with DCM, regardless of AF (ACM with AF 49% [95% CI: 44-54%], ACM without AF 48% [45-53%], DCM with AF 41% [39-42%], DCM without AF 30% [29-31%], P < 0.0001). The prognosis associated with AF was statistically significantly different in people with ACM and DCM (adjusted hazards ratio 0.85 [95% CI: 0.74-0.98] versus 1.04 [1.00-1.09] in ACM and DCM, P < 0.0001). The mortality associated with oral anticoagulation was similar in ACM and DCM (hazards ratio 0.81 [0.61-1.07] versus 0.87 [0.80-0.94], P = 0.49). CONCLUSIONS Patients with ACM had a worse prognosis when compared with patients with DCM, but this did not appear to be driven by AF. Patients with ACM were observed to have similar associated risk benefits of oral anticoagulation as DCM.

JAMA Cardiol 2022; 7:1027-1035. [PMID: 36044209 PMCID: PMC9434484 DOI: 10.1001/jamacardio.2022.2825] [Citation(s) in RCA: 16] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/19/2022] [Accepted: 07/12/2022] [Indexed: 11/14/2022]
Abstract
Importance Women have a lower incidence of atrial fibrillation (AF) compared with men in several studies, but it is unclear whether this sex difference is independent of sex differences in prevalent cardiovascular disease (CVD), body size, and other risk factors. Objective To examine sex differences in AF incidence and whether AF risk factors differ by sex in a contemporary cohort of men and women without prevalent CVD. Design, Setting, and Participants This was a prospective cohort analysis within the Vitamin D and Omega-3 Trial (VITAL) Rhythm Study, a randomized trial that examined the effect of vitamin D and ω-3 fatty acid supplementation on incident AF among men 50 years or older and women 55 years or older without a prior history of prevalent AF, CVD, or cancer at baseline. Data were analyzed from September 29, 2020, to June 29, 2021. Exposures Sex, height, weight, body mass index (BMI), body surface area (BSA), and other AF risk factors at study enrollment. Main Outcomes and Measures Incident AF confirmed by medical record review. Results A total of 25 119 individuals (mean [SD] age, 67.0 [7.1] years; 12 757 women [51%]) were included in this study. Over a median (IQR) follow-up of 5.3 (5.1-5.7) years, 900 confirmed incident AF events occurred among 12 362 men (495 events, 4.0%) and 12 757 women (405 events, 3.2%). After adjustment for age and treatment assignment, women were at lower risk for incident AF than men (hazard ratio [HR], 0.68; 95% CI, 0.59-0.77; P < .001). The inverse association between female sex and AF persisted after adjustment for race and ethnicity, smoking, alcohol intake, hypertension, diabetes (type 1, type 2, gestational), thyroid disease, exercise, and BMI (HR, 0.73; 95% CI, 0.63-0.85; P <.001). However, female sex was positively associated with AF when height (HR, 1.39; 95% CI, 1.14-1.72; P = .001), height and weight (HR 1.49, 95% CI, 1.21-1.82; P <.001), or BSA (HR, 1.25; 95% CI, 1.06-1.49; P = .009) were substituted for BMI in the multivariate model. In stratified models, risk factor associations with incident AF were similar for women and men. Conclusions and Relevance In this cohort study, findings suggest that after controlling for height and/or body size, women without CVD at baseline were at higher risk for AF than men, suggesting that sex differences in body size account for much of the protective association between female sex and AF. These data underscore the importance of AF prevention in women.

Abstract
Objective Prior work estimated excess death rates associated with atrial fibrillation (AF) in heart failure (HF) with hazard ratios (HR). The aim was to estimate the life-years lost after newly diagnosed AF in HF patients. Methods Among patients diagnosed with HF in 2008–2018 in the nationwide Danish Heart Failure Registry, we compared patients with incident AF to referents matched on age, sex, and time since HF. We estimated the marginal hazard ratio (HR) for death and marginal difference in restricted mean survival times (RMST) between AF cases and referents at 10 years after AF diagnosis. We adjusted for sex, age at AF diagnosis, clinical and lifestyle risk factors, and medications. Results Among 4463 AF cases and 17,792 referents (mean age 73.7 years, 29% women), the HR was 1.41 (95% CI 1.38; 1.44) but there was evidence of non-proportional hazards. The difference in RMST was −18.2 months (95% CI −16.8; −19.6) at 10 years after AF diagnosis. There were differences in life-years lost between patients diagnosed with AF >1 year and ≤1 year after HF (−25.7 months, 95% CI −23.7; −27.7 vs −10.4 months, 95% CI −8.2; −12.5, p < 0.001), women and men (−20.3 months, 95% CI −17.7; −21.9 vs −17.2 months, 95% CI −15.5; −19.0, p = 0.05), patients with low, medium, and high CHA2DS2-VASc (10.3 months, 95% CI −4.6; −16.1 vs −18.5 months, 95% CI −16.7; −20.4 vs 22.1, 95% CI −18.8; −22.3, p = 0.002). Conclusion HF patients with incident AF lost on average 1.5 life-years over 10 years after AF. Life-years lost were larger among patients diagnosed with AF >1 year after HF, women, and patients with higher CHA2DS2-VASc.

The Influence of Atrial Fibrillation on In-Hospital Mortality in People with Hospital-Acquired Pneumonia: An Observational, Sex-Stratified Study. J Clin Med 2022; 11:jcm11051179. [PMID: 35268270 PMCID: PMC8910951 DOI: 10.3390/jcm11051179] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2022] [Revised: 02/16/2022] [Accepted: 02/21/2022] [Indexed: 12/23/2022] Open
Abstract
(1) Background: The study aimed to analyze the influence of atrial fibrillation (AF) prior to hospital admission (“prevalent”) and new-onset AF diagnosed during hospital admission (“incident”) on in-hospital mortality (IHM) in women and men who developed hospital-acquired pneumonia (HAP) in Spain (2016−2019). (2) Methods: We used the Spanish Register of Specialized Care-Basic Minimum Database. (3) Results: We analyzed 38,814 cases of HAP (34.6% women; 13.5% ventilator-associated). Prevalent AF was coded in 19.9% (n = 7742), and incident AF in 5.5% (n = 2136) of HAP. Crude IHM was significantly higher for prevalent AF (34.22% vs. 27.35%, p < 0.001) and for incident AF (35.81% vs. 28.31%, p < 0.001) compared to no AF. After propensity score matching, IHM among women and men with prevalent AF was higher than among women and men with no AF (among women, 32.89% vs. 30.11%, p = 0.021; among men, 35.05% vs. 32.46%, p = 0.008). Similarly, IHM among women and men with incident AF was higher than among women and men with no AF (among women, 36.23% vs. 29.90%, p = 0.013; among men, 35.62% vs. 30.47%; p = 0.003). Sex was associated with a higher IHM only in people with incident AF (for female, OR = 1.21; 95% CI: 1.01−1.57). (4) Conclusions: Both prevalent and incident AF were associated with higher IHM in people who developed HAP. Female sex was associated with a higher IHM in incident AF.
