The Role of Imaging in Preventive Cardiology in Women.

PURPOSE OF REVIEW: The prevalence of CVD in women is increasing and is due to the increased prevalence of CV risk factors. Traditional CV risk assessment tools for prevention have failed to accurately determine CVD risk in women. CAC has shown to more precisely determine CV risk and is a better predictor of CV outcomes. Coronary CTA provides an opportunity to determine the presence of CAD and initiate prevention in women presenting with angina. Identifying women with INOCA due to CMD with use of cPET or cMRI with MBFR is vital in managing these patients. This review article outlines the role of imaging in preventive cardiology for women and will include the latest evidence supporting the use of these imaging tests for this purpose. RECENT FINDINGS: CV mortality is higher in women who have more extensive CAC burden. Women have a greater prevalence of INOCA which is associated with higher MACE. INOCA is due to CMD in most cases which is associated with traditional CVD risk factors. Over half of these women are untreated or undertreated. Recent study showed that stratified medical therapy, tailored to the specific INOCA endotype, is feasible and improves angina in women. Coronary CTA is useful in the setting of women presenting with acute chest pain to identify CAD and initiate preventive therapy. CAC confers greater relative risk for CV mortality in women versus (vs.) men. cMRI or cPET is useful to assess MBFR to diagnose CMD and is another useful imaging tool in women for CV prevention.

Novel Nutritional and Dietary Approaches to Weight Loss for the Prevention of Cardiovascular Disease: Ketogenic Diet, Intermittent Fasting, and Bariatric Surgery.

PURPOSE OF REVIEW: Cardiovascular disease (CVD) is highly associated with obesity and cardiometabolic dysfunction. This review will focus on three novel therapies that have been identified for potential treatment of obesity and its associated CVD risk factors. RECENT FINDINGS: Intermittent fasting (IF) studies in animal models have shown improvements in cardiometabolic factors, including improved glucose metabolism, reduced inflammation, and reduced blood pressure. However, there is still a lack of prospective human trials to support results from animal-based studies and observational data. Studies of ketogenic diets in humans have produced mixed effects in CVD risk factors. It has been shown that the ketogenic diet (KD) increases low-density lipoprotein cholesterol (LDL-C) but decreases triglycerides. Additionally, implementation of KD in rodent studies have demonstrated increased insulin resistance and glucose intolerance. Bariatric surgery is a useful tool to help patients with obesity lose significant amounts of weight while alleviating CVD risk factors such as hypertension, LDL-C levels, triglyceride levels, and diabetes. The type of procedure influences degree of improvement in weight and CVD risk factors, yet complications remain possible. IF and bariatric surgery offer potential for weight loss and treatment of CVD risk factors. Negative cardiovascular effects of KD have been noted and should be considered before recommending this diet to patients, particularly those with established cardiovascular disease.

Clinical, Sociodemographic, and Neighborhood Characteristics Associated with Adverse Pregnancy Outcomes.

Background: Cardiovascular risk is increased by a history of adverse pregnancy outcomes (APOs). Efforts to understand and prevent these adverse outcomes may improve both fetal and birthing persons' outcomes in the peripartum period, and over the patient's lifetime. This study aims to assess the association of clinical, sociodemographic, and economic neighbor-hood factors with preterm birth (PTB) and APOs (the composite of stillbirth, small for gestation age, and low birthweight). Materials and Methods: This is a cross-sectional study using the electronic medical records of deliveries from seven Northwell Health hospitals between January 1, 2018 and July 31, 2020. There were 62,787 deliveries reviewed in this study. Deliveries that were not the first for the patient during the study period and multiple gestational pregnancies were excluded. Patients with incomplete data on outcome were also excluded. Main outcomes were PTB and composite APOs. Measures included history of PTB, hypertension, diabetes, body mass index, race/ethnicity, age, preferred language, marital status, parity, health insurance, and median income, percent unemployment, and mean household size by zip code. Results: Of the 62,787 deliveries, 43.3% were from white, Non-Hispanic, and Non-Latino patients. There were 4,552 (7.2%) PTBs and 8,634 (13.8%) APOs. Patients enrolled in public insurance had higher odds of PTB (odds ratio [OR] 1.15, 95% CI 1.06-1.24) and APOs (OR 1.19, 95% CI 1.12-1.25). There was a statistically significant association of both PTB (p = 0.037) and APOs (p = 0.005) when comparing patients that live in a zip code with a median income over 100k to those with an income <100k. In addition, living in a zip code within the second quintile of unemployment was associated with lower odds of APOs (OR 0.92, 95% CI 0.84-0.99). Conclusions: Numerous sociodemographic and clinical factors are associated with both PTB and APOs. Tailored programs addressing these disparities may improve outcomes in pregnant persons.

Managing cardiometabolic risk factors across a woman's lifespan: A lipidologist's perspective.

A recent rise in atherosclerotic cardiovascular disease (ASCVD) mortality in women warrants a heightened focus on the cardiometabolic risk factors that are closely tied to increasing trends in obesity and suboptimal lifestyle. Polycystic ovarian syndrome (PCOS), adverse pregnancy outcomes (APOs) and nonalcoholic fatty liver disease (NAFLD) are often manifestations of cardiometabolic disease that convey cardiovascular risk requiring recognition foremost, as well as a targeted approach to treatment. Similarly, menopause is a time to reflect on a woman's cardiovascular risk as multiple cardiometabolic changes occur during this time. Contraceptives and menopausal replacement therapy (MRT) should be considered along with a woman's individual thrombotic and cardiovascular risk. Clinicians should be attuned to cardiometabolic risk factors throughout a woman's lifespan and familiar with strategies to reduce cardiovascular risk.

Racial differences in the incidence of atrial fibrillation after cryptogenic stroke.

BACKGROUND: The incidence of atrial fibrillation (AF) is lower in nonwhites than in whites despite a higher burden of AF risk factors. However, the incidence of new AF after cryptogenic stroke in minorities is unknown. OBJECTIVE: The purpose of this study was to determine the incidence of AF after cryptogenic stroke in different racial/ethnic groups. METHODS: We retrospectively analyzed 416 consecutive patients undergoing insertable cardiac monitor implantation at our hospital from 2014 through 2019. Incidence of AF was identified through the review of device monitoring, including adjudication of AF episodes for accuracy, and compared by race. RESULTS: The mean follow-up time was 1.5 ± 1.1 years. The predominantly nonwhite cohort included 244 (59%) blacks and 109 (26%) Hispanics, and 45% (n=189) were male. The mean age was 62 ± 12 years; Blacks and Hispanics had more hypertension, diabetes, and chronic kidney disease and higher body mass index than did whites. In blacks and Hispanics, the cumulative incidences of AF at 1, 2, and 3 years were 14.1%, 19.9%, and 24% and 12.9%, 18.3%, and 20.9%, respectively. By comparison, the incidence in whites was significantly higher: 20.8%, 34.3%, and 40.3%. In a Cox proportional hazards model adjusting for common AF risk factors, blacks (hazard ratio 0.49; confidence interval 0.26-0.82; P = .03) and Hispanics (hazard ratio 0.39; confidence interval 0.18-0.83; P = .01) were less likely to have incident AF than whites. CONCLUSION: In patients with an insertable cardiac monitor after cryptogenic stroke, the incidence of newly detected AF is approximately double in whites compared with both blacks and Hispanics. This has important implications for the investigation and treatment of nonwhites with cryptogenic stroke.
