Background/Objectives: In the United States, HF prevalence is projected to progressively rise by 2030. Prior research suggests a strong association between reduced sleep duration and increased cardiovascular disease and HF risk. This study introduces an alternative parameter, the weekend sleep recovery (WSR), measured by the weekend-to-weekday sleep duration ratio (SDR), to evaluate its association with HF risk. Methods: We conducted a cross-sectional analysis of NHANES (National Health and Nutrition Examination Survey) 2017–2023 to examine self-reported sleep patterns. Participants were classified as WSR (SDR > 1) or non-WSR (SDR ≤ 1). Multivariate logistic regression assessed the association between WSR and HF, adjusting for demographics and comorbidities. Results: Among 8320 participants included in the fully adjusted analysis, WSR was associated with lower odds of HF compared with non-WSR (adjusted OR 0.73, 95% CI 0.55–0.96; p = 0.026). A significant interaction was observed between WSR and weekday sleep duration (P for interaction = 0.003), whereas no interaction was found with weekend sleep duration. In exploratory subgroup analyses, nominally significant associations were observed in several clinical subgroups; however, after correction for multiple comparisons, only participants without dyslipidemia retained statistical significance. No significant effect modification by race/ethnicity was observed (P for interaction = 0.436). Conclusions: Weekend sleep recovery was associated with lower odds of HF in this cross-sectional study. The association varied according to weekday sleep duration but was generally consistent across racial/ethnic groups. Given the observational design, these findings should be interpreted as associative rather than causal and warrant confirmation in prospective studies.

Atrial fibrillation (AF) is the most common cardiac arrhythmia and is associated with increased morbidity, mortality, and healthcare expenses. Meanwhile, effective management of AF requires a comprehensive, patient-centered approach that includes risk factor modification, rate and rhythm control strategies, and prevention of thromboembolic events. Multidisciplinary AF clinics have emerged as a model for comprehensive management to improve patient outcomes and reduce healthcare burden. This review discusses the rationale, structure, benefits, challenges, and future directions of multidisciplinary AF clinics, emphasizing their role in optimizing AF management.

Background: There is suspicion that estrogen may protect against atherosclerosis. Women who experience menarche earlier, and thus have earlier estrogen exposure, might develop atherosclerosis later. The relationship between menarche age and the onset of angina pectoris, a symptom of coronary artery disease, remains unknown. Goal: This study aims to find the correlation between menarche age and the onset age of angina pectoris, and the association between early menarche (onset of menarche ≤ 10 y/o) and early onset of angina pectoris (onset of angina pectoris ≤ 40 y/o). Methods: A cross-sectional study using a population from the 2017-2020 National Health and Nutrition Examination Survey (NHANES). The question collects self-reported data on onset of menarche and onset of angina pectoris. The relationship between menarche age and age in onset of angina pectoris was analyzed by linear and logistic regression analysis. Multivariate analysis adjusted for race, age, body mass index (BMI), smoking , diabetes mellitus (DM), hypertension, and dyslipidemia status. Results: Among 4,816 females who reported their menarche age, 88(1.8 %) have had an angina pectoris. The study involved 82 females who reported both the age of menarche and the age of onset of angina pectoris. The mean ± SD of the age at menarche and the age at onset of angina pectoris was 12.53 ± 1.79 y/o and 51.66 ± 15.16 y/o, respectively. The study found a significant association between the menarche age and the age at onset of angina pectoris. After adjusting for confounders, we found that every 1-year increase in the age of menarche will delay the onset of angina pectoris by 1.43 years, with a 95% CI of 0.01 to 2.86.(Table 1A,Graph 1A-1B) We also found that early menarche has a significantly increased risk 2.8 times (95%CI: 1.3, 6.2) of early onset of angina pectoris.After adjusting for confounders, the association became even stronger. The odds ratio (OR) increased to 3.3 (95%CI: 1.4, 8.0), indicating that women with early menarche were 3.3 times more likely to experience early angina pectoris compared to those with later menarche.(Table 2A) Conclusion: In contrast to our hypothesis, age at menarche is positively associated with onset of angina pectoris. The earlier onset of menarche is linked to the earlier onset of angina pectoris. We suspected that factors beyond estrogen levels may contribute to this unexpected finding. Additional studies are needed to examine the cause of this correlation.
