Abstract 4140180: The Effect of Benzodiazepine Use in Patients with Atrial Fibrillation and Obstructive Sleep Apnea

Circulation, Volume 150, Issue Suppl_1, Page A4140180-A4140180, November 12, 2024. Introduction:Sleep apnea is a common sleep disorder that can worsen atrial fibrillation(AF) prognosis. Benzodiazepines(BZD) are commonly prescribed for insomnia, which often accompanies sleep apnea. However, BZDs have been associated with worsening of sleep apnea due to respiratory depression, pharyngeal muscle relaxation, and increase of arousal threshold, which all may lead to prolonged hypoxia. There is little research on the effect of BZD use in AF patients with sleep apnea. Therefore, the objective of this study is to investigate the effects of BZD usage on outcomes in the AF population with sleep apnea.Methods:Data from patients with AF and sleep apnea seen at Tulane Medical Center between 2010 and 2019 was obtained from Research Action for Health Network(REACHnet), a Clinical Research Network in PCORnet®. Patients with AF and sleep apnea were divided between those with a prescription of BZD and those without BZD. These two groups were compared using the Kaplan-Meier method for time-to outcome for all-cause mortality, ischemic stroke, myocardial infarction(MI), and hospitalizations in the five years following their AF diagnosis. Cox regression analysis was used to investigate proportional hazards and control for demographics, comorbidities, and medication use.Results:There were 524 total patients included with AF and sleep apnea. Of these, 413(78.8%) were not prescribed BZDs, while 111(21.1%) were taking BZDs. Use of BZDs was associated with worse outcomes. In the no BZD and the BZD group over the 5 years following AF diagnosis, the rate of mortality was 6.1% and 12.6%(p

Abstract 4147625: Cardiometabolic Syndrome and Incident Alzheimer’s Disease: The Predicative Value of Age and CMS Using Cox and Machine Learning Models

Circulation, Volume 150, Issue Suppl_1, Page A4147625-A4147625, November 12, 2024. Background:Cardiometabolic syndrome (CMS) poses a significant public health concern. The study aimed to investigate the predictive value of age and CMS for incident Alzheimer’s disease (AD) in women aged≥50.Methods:A cohort of women aged 50-79 (n= 63,117) who participated in the Women’s Health Initiative Observational Study (WHIOS) in 1993-1998, without baseline AD and followed through to March 1, 2019, were analyzed. CMS was defined as having ≥3 of five CMS components: large waist circumference, HBP, elevated triglycerides, elevated glucose, and low HDL-cholesterol. AD was classified by physician-diagnoses of incident AD. Hazards ratios (HR) of AD risk associated with CMS by age were analyzed using Cox’s proportional hazards regression analysis. Machine learning (ML)-XGBoost and Lasso Cox models clustered individuals with low, mild, moderate, and severe risk of incident AD.Results:During a median follow-up of 20 years (range: 3.36 to 23.36 years), 8340 developed incident AD. The incident rate (95%CI) of AD was 8.6 (8.1-9.1) per 1000 person-years (PY) in women with CMS, and 7.0 (6.9-7.2) per 1000 PY in those without CMS (p

Abstract 4136600: Hypertensive disorders of pregnancy and the risk of Dementia, Alzheimer’s disease, and Vascular Dementia. A Systematic review and Meta-analysis of 25,03,538 women participants.

Circulation, Volume 150, Issue Suppl_1, Page A4136600-A4136600, November 12, 2024. Background:Hypertensive disorders of pregnancy (HDP) are associated with maternal adverse cardiovascular outcomes. However, their association with maternal Dementia and Alzheimer’s disease is not well established with limited and conflicting results to date.Objective:We sought to evaluate the association between HDP and risk of incidence of Dementia, and Alzheimer’s disease.Methods:We performed a systematic review and meta-analysis of available literature that enrolled women with HDP and women without HDP groups. PubMed, Embase and ClinicalTrials.gov were systematically searched from inspection till May 2024 without any language restrictions. Adjusted hazard ratios (aHR) and 95% confidence intervals (CI) were pooled using a random-effect model.Results:A total of 8 studies with 2503538 patients (1,51,905 in women with HDP and 23,51,633 in the women without HDP group) were included. Pooled analysis shows that HDP women were having 37% higher risk of dementia (aHR, 1.37(95%CI: 1.27-1.46), P
