Background: Seven million lesbian, gay, and bisexual (LGB) adults will be aged >50 years by 2030; assessing and addressing their risk for cardiovascular disease is critical.
Methods And Results: We analyzed a nationwide cohort using the Veterans Health Administration data. Sexual orientation (SO) was classified via a validated natural language processing algorithm. Prevalent atherosclerotic cardiovascular disease (ASCVD) (history of acute myocardial infarction, ischemic stroke, or revascularization) was identified via ( and ) codes. The index date was the date of the first primary care appointment on or after October 1, 2009. We ascertained covariates and prevalent ASCVD in the year following the index date; the baseline date was 1 year after the index date. We calculated sample statistics by sex and SO and used logistic regression analyses to assess associations between SO and prevalent ASCVD. Of 1 102 193 veterans with natural language processing-defined SO data, 170 861 were classified as LGB. Prevalent ASCVD was present among 25 031 (4105 LGB). Adjusting for age, sex, race, and Hispanic ethnicity, LGB veterans had 1.24 [1.19-1.28] greater odds of prevalent ASCVD versus non-LGB identified veterans. This association remained significant upon additional adjustment for the ASCVD risk factors substance use, anxiety, and depression (odds ratio [OR],1.17 [95% CI, 1.13-1.21]). Among a subset with self-reported SO, findings were consistent (OR, 1.53 [95% CI, 1.20-1.95]).
Conclusions: This is one of the first studies to examine cardiovascular risk factors and disease of the veteran population stratified by natural language processing-defined SO. Future research must explore psychological, behavioral, and physiological mechanisms that result in poorer cardiovascular health among LGB veterans.

Background: Cardiovascular diseases (CVDs) are one of the most prevalent causes of mortality worldwide, especially significant in low- and middle-income countries. Kyrgyzstan and India represent such nations that face a huge burden of CVD-related deaths globally. Understanding the prevalence of traditional cardiovascular risk factors (CVRFs) in these populations is critical for effective prevention and management strategies.

Background: The prevalence of very high-risk atherosclerotic cardiovascular disease (ASCVD) is significant in China, with suboptimal rates of low-density lipoprotein cholesterol (LDL-C) compliance exacerbating plaque instability and causing a higher incidence of major adverse cardiac events (MACEs). Proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i) are effective in reducing LDL-C levels, increase the stability of vulnerable plaque, and influence the progression of atherosclerosis through multiple mechanisms as demonstrated in animal studies. However, there is currently a lack of evidence regarding the efficacy and safety of high-intensity statin therapy combined with PCSK9i in the secondary prevention of ASCVD in the Chinese population.

Background: Remnant cholesterol (remnant-C) contributes to atherosclerotic cardiovascular disease (ASCVD), particularly in individuals with impaired glucose metabolism. Patients with impaired glucose metabolism and ASCVD remain at significant residual risk after coronary artery bypass grafting (CABG). However, the role of remnant-C in this population has not yet been investigated.

Background: The prevalence, chronicity and clinical impact of type 2 diabetes (T2D) defines this disease state as a critical determinant in morbidity and mortality, as encountered by individuals, health care systems, and public health in general. The need to understand and optimize T2D identification and management is now further heightened by the advent of medications with established cardiovascular (CV) and kidney benefits in such patients, namely sodium-glucose cotransporter 2 inhibitors (SGLT2i) and glucagon-like peptide 1 receptor agonists (GLP-1 RA). Prescription rates for these agents have remained low despite guidelines incorporating and emphasizing their use.
