Atherosclerosis and HIV: Exploring Cardiovascular Risks and Management.

The advent of antiretroviral therapy has markedly improved the life expectancy of individuals with HIV, leading to a shift in clinical focus from managing opportunistic infections to addressing chronic conditions, such as atherosclerotic cardiovascular disease (ASCVD). Emerging evidence highlights an elevated risk of ASCVD among people living with HIV, characterized by a higher incidence of acute myocardial infarction, ischemic stroke, and heart failure compared with the general population. This review examines the epidemiology, pathophysiology, and management of ASCVD in the context of HIV. It explores the interplay between HIV infection, antiretroviral therapy, and traditional cardiovascular risk factors, underscoring the need for comprehensive cardiovascular risk reduction strategies tailored to people living with HIV. Through synthesizing data from clinical trials, observational studies, and basic research, the review aims to enhance understanding of HIV-associated ASCVD and inform healthcare practices to improve the longevity and quality of life for this patient population.

Pulmonary Artery Hypertension: Fifty Years Following Pneumonectomy in Infancy.

Pulmonary hypertension (PH) may be the result of many different pathological processes. PH is a rare but recognized vascular complication following major lung resection. We describe the diagnosis and management of moderate PH resulting more than 50 years in a patient who underwent a total unilateral pneumonectomy in infancy. Unfortunately, patients who undergo pneumonectomy will likely go on to develop PH and their functional status will be greatly impacted. In the case presented, we report on a patient whose PH and symptoms improved following off-label WHO group 1 treatment.

High-Risk Pulmonary Hypertension Does Not Worsen Outcomes in Heart Transplantation.

Pulmonary hypertension (PH) is a relative contraindication to heart transplantation (HT). Multiple studies showed increased mortality in patients with PH. Advances in care may have led to improved outcomes in the modern era. We analyzed patients who underwent HT at our institution between 2014 and 2018. We divided patients into 2 groups based on the presence of high-risk PH defined as either pulmonary vascular resistance >3 Wood units or transpulmonary gradient >15 mm Hg. The primary outcome was survival. Secondary outcomes were post-HT morbidity and changes in hemodynamics. Subsequently, we analyzed national trends of single organ HT recipients with a high-risk PH between 1994 and 2018 from the United Network for Organ Sharing registry. Of 98 patients who underwent HT at our center, 32% had PH. In patients without and with PH, the survival was 100% at 30 days, 87%, and 81% at 3 years (p = 0.96). In both groups, pulmonary vascular resistance and trans-pulmonary gradient decreased after HT. Nationwide data revealed 30-day survival without and with PH at 97% and 98% (p = 0.47) and 3-year survival at 86% and 87% (p = 0.84), respectively, in 2018. The proportion of recipients with PH decreased from 25% in 1994 to 19% in 2018. Recipients of HT with and without high-risk PH had similar early and late mortality in a single-center and nationwide analysis. PH improved immediately after transplant. The United Network for Organ Sharing registry analysis demonstrates continued improvement in survival in patients with PH in the modern era, whereas the relative percentage of recipients with PH decreased over time.

Safety and cardiometabolic efficacy of novel antidiabetic drugs.

INTRODUCTION: There are three major drug classes discussed in this review: dipeptidyl dipeptidase-4 (DPP4) inhibitors, glucagon-like peptide-1 receptor agonists (GLP-1 RAS), and sodium-glucose cotransporter-2 (SGLT2) inhibitors. A literature review of the landmark cardiovascular outcome trials from 2008 to 2021 was conducted. AREAS COVERED: The cumulative data shown in this review suggest that in patients with Type 2 Diabetes (T2D), SGLT2 inhibitors and GLP-1 RAS may reduce cardiovascular (CV) risk. Specifically, in the heart failure (HF) population, SGLT2 inhibitors have shown a reduction in hospitalizations in some randomized controlled trials (RCTs). DPP4 inhibitors have not shown a similar reduction in CV risk and even exhibited an increase in hospitalizations for HF in one RCT. It is important to note that the DPP4 inhibitors did not demonstrate an increase in major CV events, with the exception of the increase in HF hospitalizations in the SAVOR TIMI 53 trial. EXPERT OPINION: Future avenues of research to explore include the use of novel antidiabetic agents to reduce post-myocardial infarction (MI) CV risk and arrhythmias independent of their use as diabetic agents.

Hyperlipidemia in Children and Adolescents.

While coronary artery disease (CAD) is thought to be a disease of adulthood, atherosclerosis can originate in childhood and adolescence. There is a paucity of randomized controlled treatment trials regarding dyslipidemia among the younger population. However, it is apparent that childhood dyslipidemia is associated with an earlier onset of CAD. Most recent guidelines by the American College of Cardiology (ACC) and American Heart Association (AHA) focus on lifestyle modification and lifetime risk of atherosclerotic disease, as well as adequate screening measures. Genetic factors, environmental contributors such as pollution, obesity linked to poor nutrition, and sedentary lifestyles are shown to be associated with increased lipid levels and early CAD among children and adolescents. Familial hyperlipidemia is one of the most prevalent genetic diseases and can affect 1 in 250 individuals. A multimodal treatment plan is most effective for children and adolescents with dyslipidemia including lifestyle changes (a modified diet and moderate physical activity) and pharmacologic intervention. The mainstay of pharmacologic treatment for childhood dyslipidemia is similar to that of adults. Statins are the most widely used medications. Newer medications have proven integral in treatment for genetic dyslipidemias including evolocumab and evinacumab.

The Past, Present, and The Future of Carcinoid Heart Disease.

Carcinoid heart disease is a frequent manifestation of carcinoid syndrome. It results from the release of a large amount of serotonin and subsequently fibrosis of right sided heart valves, that is, tricuspid and pulmonic valve. This article reviews the pathogenesis, clinical symptoms, diagnosis, treatment and prognosis of carcinoid heart disease. Recent developments in treating carcinoid heart disease have improved the poor prognosis associated with the disease.

Trends in 10-Year Predicted Risk of Cardiovascular Disease Associated With Food Insecurity, 2007-2016.

Introduction: Consumption of a healthy diet improves cardiovascular (CV) risk factors and reduces the development of cardiovascular disease (CVD). Food insecure (FIS) adults often consume an unhealthy diet, which can promote obesity, type 2 diabetes mellitus (T2DM), hypertension (HTN), and hyperlipidemia (HLD). The Supplemental Nutrition Assistance Program (SNAP) is designed to combat food insecurity by increasing access to healthy foods. However, there is a paucity of data on the association of SNAP participation among FIS adults and these CVD risk factors. Methods: The National Health and Nutrition Examination Survey (NHANES) is a publicly available, ongoing survey administered by the Centers for Disease Control and Prevention and the National Center for Health Statistics. We analyzed five survey cycles (2007-2016) of adult participants who responded to the CVD risk profile questionnaire data. We estimated the burden of select CVD risk factors among the FIS population and the association with participation in SNAP. Results: Among 10,449 adult participants of the survey, 3,485 (33.3%) identified themselves as FIS. Food insecurity was more common among those who were younger, female, Hispanic, and Black. Among the FIS, SNAP recipients, when compared to non-SNAP recipients, had a lower prevalence of HLD (36.3 vs. 40.1% p = 0.02), whereas rates of T2DM, HTN, and obesity were similar. Over the 10-year survey period, FIS SNAP recipients demonstrated a reduction in the prevalence of HTN (p < 0.001) and HLD (p < 0.001) which was not evident among those not receiving SNAP. However, obesity decreased only among those not receiving SNAP. The prevalence of T2DM did not change over the study period in either group. Conclusion: Over a 10-year period, FIS adults who received SNAP demonstrated a reduction in the prevalence of HTN and HLD, which was not seen among those not receiving SNAP. However, the prevalence of obesity and T2DM did not decline among SNAP recipients, suggesting that additional approaches are required to impact these important CVD risk factors.

Wellens' syndrome: a rare presentation after an endoscopic retrograde cholangiopancreatography.

Wellens' syndrome is a pattern of ECG changes typically seen in patients with unstable angina that has a high positive predictive value for critical left anterior descending coronary artery stenosis. Recognition of this syndrome can allow for intervention before the patient develops myocardial infarction. We report a case of Wellens' syndrome that was observed after an endoscopic retrograde cholangiopancreatography, which highlights risk factors that needs consideration in evaluating patients with these ECG findings after undergoing procedures even when asymptomatic.
