Cholesterol Paradigm and Beyond in Atherosclerotic Cardiovascular Disease: Cholesterol, Sterol Regulatory Element-Binding Protein, Inflammation, and Vascular Cell Mobilization in Vasculopathy.

Hypercholesterolemia is a well-established risk factor for atherosclerotic cardiovascular disease (ASCVD). How cholesterol and its carrier lipoproteins are involved in ASCVD is still under extensive investigation. Satins are thus far the best-proven class of cholesterol-lowering medications to improve the clinical outcomes of ASCVD.

A Review of the Role of Type 2 Diabetes Mellitus and Sodium-Glucose Cotransporter-1 Inhibitors in Heart Failure With Preserved Ejection Fraction.

Previous research has demonstrated that patients with type 2 diabetes (T2DM) are at an increased risk for cardiovascular events, including heart failure (HF). Moreover, there is a higher risk of mortality in individuals who have both T2DM and HF with preserved ejection fraction (HFpEF). Although there are antidiabetic agents that have shown both cardiovascular safety and improved cardiovascular outcomes, only certain agents have been associated with HF benefits, such as sodium-glucose cotransporter-2 (SGLT2) inhibitors.

Conduction Disturbances and Permanent Pacemaker Implantation After Transcatheter Aortic Valve Replacement: Predictors and Prevention.

Conduction disturbances and permanent pacemaker implantation (PPMI) remain a frequent and important consequence of transcatheter aortic valve replacement (TAVR). Understanding risk factors for TAVR-related conduction disturbances could improve patient selection, procedural techniques, and periprocedural efforts for monitoring and treatment of heart block. Several studies have identified patient-related and procedural factors associated with new-onset left bundle branch block, high-degree atrioventricular block, and the need for PPMI after TAVR.

The Case For Cadmium and Lead Heavy Metal Screening.

Exposure to cadmium and lead is widespread, and is related to environmental contamination, occupational sources, food, tobacco and other consumer products. Lower socioeconomic status increases the risk of heavy metal exposure and the diseases associated with cadmium and lead toxicity. Concurrent toxicity with both cadmium and lead is likely but has not often been assessed.

Dual Versus Triple Therapy in Patients with Acute Coronary Syndrome and an Anticoagulation Indication: A Systematic Review with Meta-Analysis and Trial-Sequential Analysis.

Choosing an antithrombotic regime in patients with acute coronary syndrome (ACS) and a concomitant indication for anticoagulation is a challenge commonly encountered by clinicians. Our aim in this article is to evaluate the safety and efficacy of triple antithrombotic therapy (TT, anticoagulant plus dual antiplatelet) versus dual antithrombotic therapy [dual therapy (DT), anticoagulant plus single antiplatelet] in patients with ACS. We included all randomized trials comparing the outcomes of single versus dual antiplatelet therapy in patients with ACS on anticoagulants.

Therapeutic Implications of NLRP3-Mediated Inflammation in Coronary Artery Disease.

Atherosclerosis is considered a chronic, inflammatory disease responsible for more than 15% of all global deaths, secondary to its complications of myocardial infarction, vascular disease, and stroke. Current treatment regimens consist of lipid-lowering pharmaceuticals, control of risk factors, and prevention of plaque rupture and thrombosis with antiplatelet agents. However, a significant burden on society remains due to the morbidity and mortality of coronary artery disease despite our best practices.

Cardiovascular and Cerebrovascular Complications With COVID-19.

The coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus-2 has affected the health of people across the globe. Cardiovascular diseases (CVDs) have a significant relationship with COVID-19, both as a risk factor and prognostic indicator, and as a complication of the disease itself. In addition to predisposing to CVD complications, the ongoing pandemic has severely affected the delivery of timely and appropriate care for cardiovascular conditions resulting in increased mortality.

Sex differences in heart failure hospitalisation risk following acute myocardial infarction.

Objective: We evaluated the sex differences in 6-month heart failure (HF) hospitalisation risk in acute myocardial infarction (AMI) survivors.

Methods: For this retrospective cohort analysis, adult survivors of an AMI between January and June 2014 were identified from the US Nationwide Readmissions Database. The primary outcome was a HF hospitalisation within 6 months.

Characteristics and Outcomes of Patients 80 Years and Older Hospitalized With Coronavirus Disease 2019 (COVID-19).

Patients older than 65 years hospitalized with COVID-19 have higher rates of intensive care unit admission and death when compared with younger patients. Cardiovascular conditions associated with COVID-19 include myocardial injury, acute myocarditis, cardiac arrhythmias, cardiomyopathies, cardiogenic shock, thromboembolic disease, and cardiac arrest. Few studies have described the clinical course of those at the upper extreme of age.

β-Arrestin as a Therapeutic Target in Heart Failure.

Heart failure is a major source of morbidity and mortality, driven, in part, by maladaptive sympathetic hyperactivity in response to poor cardiac output. Current therapies target β-adrenergic and angiotensin II G protein-coupled receptors to reduce adverse cardiac remodeling and improve clinical outcomes; however, there is a pressing need for new therapeutic approaches to preserve cardiac function. β-arrestin is a multifunctional protein which has come under analysis in recent years as a key player in G protein-coupled receptor signal transduction and a potential therapeutic target in heart failure.

The Impact on Medical Students of the 9/11 Attacks on New York's World Trade Center.

Little is known about how participation in disaster relief impacts medical students. During the terror attacks of September 11, 2001, New York Medical College School of Medicine students witnessed the attacks and then became members of emergency treatment teams at St. Vincent's Hospital, the trauma center nearest to the World Trade Center.

A Novel Calcium Channel Blocker: Etripamil: What is the Future of Intranasal Drug Delivery in the Treatment of Cardiac Arrhythmias?

Symptomatic paroxysmal cardiac arrhythmias are common cardiac conditions that lead to a decreased quality of life, increased healthcare costs, and significant morbidity. Many cardiac arrhythmias increase in frequency with age, and as the elderly population continues to increase, so will the incidence and prevalence of cardiac arrhythmias. The long-term treatment options for patients with paroxysmal arrhythmias include ablation procedures and daily oral antiarrhythmics.

Firibastat: An Oral First-in-Class Brain Aminopeptidase A Inhibitor for Systemic Hypertension.

Systemic hypertension is the leading cause of death and disability worldwide. The management of hypertension is challenging in the high-risk patient population with high salt-sensitivity and low serum renin levels. The renin-angiotensin system (RAS) plays a central role in blood pressure (BP) regulation.

Review of the Protective Effects of Statins on Cognition.

Elevated cholesterol is a major risk factor in the development of cardiovascular disease. Statins have proven to be effective in lowering low-density lipoprotein cholesterol as well as the incidence of cardiovascular events. As a result, statins are widely prescribed in the United States, with an estimated 35 million patients on statins.

Use of Nonsteroidal Anti-inflammatory Drugs for COVID-19 Infection: Adjunct Therapy?

Severe acute respiratory distress syndrome coronavirus 2 (COVID-19) is the cause of the current pandemic, which remains a tremendous cause of morbidity and mortality worldwide. Although there are numerous trials underway, there is currently no medication known to cure the infection. Nonsteroidal anti-inflammatory drugs (NSAIDs) are inexpensive, widely available medications with antiviral and anti-inflammatory properties and may have utility as an adjunct therapy to improve outcomes in patients with severe COVID-19 infection.

Noninvasive Radioablation of Ventricular Tachycardia.

Ventricular tachycardia (VT) occurs most commonly in the presence of structural heart disease or myocardial scarring from prior infarction. It is associated with increased mortality, especially when it results in cardiac arrest outside of a hospital. When not due to reversible causes (such as acute ischemia/infarction), placement of an implantable cardioverter-defibrillator for prevention of future sudden death is indicated.

Corynebacterium Jeikeium Endocarditis: A Review of the Literature.

Corynebacterium jeikeium is a gram-positive, aerobic, pleomorphic, nonspore forming bacillus, commonly present on the skin surface. Infective endocarditis secondary to C. jeikeium most commonly affects left-sided heart valves and has a higher likelihood to require valve replacement compared to other Corynebacterium endocarditis.

Myocardial Infarction With Nonobstructive Coronary Arteries.

Myocardial infarction with nonobstructive coronary arteries (MINOCA) is the current term used to describe patients who have a myocardial infarction but have normal, non-obstructed coronary arteries on a coronary angiogram. There is still much debate over the definition, diagnosis, management and treatment of MINOCA. However, MINOCA is not a benign condition; prompt recognition and diagnosis can lead to better management and treatment and thus improve patient outcomes.
