Tailored Therapies for Cardiogenic Shock in Hypertrophic Cardiomyopathy: Navigating Emerging Strategies.

Hypertrophic cardiomyopathy (HCM) is a complex and heterogeneous cardiac disorder, often complicated by cardiogenic shock, a life-threatening condition marked by severe cardiac output failure. Managing cardiogenic shock in HCM patients presents unique challenges due to the distinct pathophysiology of the disease, which includes dynamic left ventricular outflow tract obstruction, diastolic dysfunction, and myocardial ischemia. This review discusses current and emerging therapeutic strategies tailored to address the complexities of HCM-associated cardiogenic shock and other diseases with similar pathophysiology that provoke left ventricular outflow tract obstruction.

Impairment in Right Ventricular-Pulmonary Arterial Coupling in Overweight and Obesity.

The association of obesity with right ventricular function and the interplay between right heart and pulmonary circulation is incompletely understood. We evaluate the role of obesity as a determinant of right ventricular-pulmonary artery coupling (RVAC). We retrospectively studied consecutive subjects without overt cardiovascular or pulmonary disease.

The Role of Ranolazine in Heart Failure-Current Concepts.

Heart failure is a complex clinical syndrome with a detrimental impact on mortality and morbidity. Energy substrate utilization and myocardial ion channel regulation have gained research interest especially after the introduction of sodium-glucose co-transporter 2 inhibitors in the treatment of heart failure. Ranolazine or N-(2,6-dimethylphenyl)-2-(4-[2-hydroxy-3-(2-methoxyphenoxy) propyl] piperazin-1-yl) acetamide hydrochloride is an active piperazine derivative which inhibits late sodium current thus minimizing calcium overload in the ischemic cardiomyocytes.

Prolonged impact of anti-cancer therapy on endothelial function and arterial stiffness in breast cancer patients.

Background: Cardiotoxicity restricts anthracycline and trastuzumab treatment of Human Epidermal Growth Factor Receptor 2 positive early breast cancer. Endothelial dysfunction and arteriosclerosis are significant cardiovascular risk factors.

Objectives: We studied the effect of anthracycline-based chemotherapy, with or without trastuzumab, on endothelium and arteriosclerosis in patients with breast cancer.

Novel Approaches to the Management of Diabetes Mellitus in Patients with Coronary Artery Disease.

Cardiovascular disease (CVD) is the leading cause of morbidity and mortality in individuals with diabetes mellitus (DM). Although benefit has been attributed to the strict control of hyperglycemia with traditional antidiabetic treatments, novel antidiabetic medications have demonstrated cardiovascular (CV) safety and benefits by reducing major adverse cardiac events, improving heart failure (HF), and decreasing CVD-related mortality. Emerging data underline the interrelation between diabetes, as a metabolic disorder, and inflammation, endothelial dysfunction, and oxidative stress in the pathogenesis of microvascular and macrovascular complications.

Lipoprotein(a) in Atherosclerotic Diseases: From Pathophysiology to Diagnosis and Treatment.

Lipoprotein(a) (Lp(a)) is a low-density lipoprotein (LDL) cholesterol-like particle bound to apolipoprotein(a). Increased Lp(a) levels are an independent, heritable causal risk factor for atherosclerotic cardiovascular disease (ASCVD) as they are largely determined by variations in the Lp(a) gene (LPA) locus encoding apo(a). Lp(a) is the preferential lipoprotein carrier for oxidized phospholipids (OxPL), and its role adversely affects vascular inflammation, atherosclerotic lesions, endothelial function and thrombogenicity, which pathophysiologically leads to cardiovascular (CV) events.

The Association of Depression With QT Duration: A Comparison Between Individuals Younger or Older Than 65 Years.

Objective: The electrocardiogram-derived corrected QT (QTc) interval is an indicator of cardiac autonomic activity that has been proposed as a biological measure to investigate the interplay between depression and cardiovascular diseases. This study assesses whether depression is associated with a longer QTc interval across age groups.

Methods: Assessment of depressive symptoms was performed in 1637 participants of the cross-sectional Corinthia study with the Zung Self-Rating Depression Scale in those younger than 65 years (group 1) and with the Geriatric Depression Scale in elderly individuals (≥65 years, group 2).

COVID-19, Endothelium and the Cardiometabolic Patient: A Possible Role for Capillary Leak Syndrome.

Capillary leak syndrome is an under-diagnosed condition leading to serious hypoalbuminemia with diffuse edema, pulmonary edema, severe hypotension, and possibly death. Sepsis leading to hemophagocytic lymphohistiocytosis (HLH) is a major risk factor; however, capillary hyper-permeability is the core underlying pathophysiological mechanism. Endothelial dysfunction plays a major role in cardiometabolic disease through insulin resistance, lipotoxicity, and, eventually, oxidative stress and chronic inflammation.

Expression of Tissue microRNAs in Ascending Aortic Aneurysms and Dissections.

Little is known about the role of serum and tissue mediators in the progression of ascending aortic aneurysms and dissections. We examined how the tissue expression of microRNAs and matrix metalloproteinases (MMPs), as well as the serum levels of osteoprotegerin, adiponectin, and high sensitivity C-reactive protein (hsCRP) are associated with these entities. We enrolled 21 patients with ascending aortic aneurysm, 11 with acute Stanford type A aortic dissection and 18 controls.

The Association of Physical Activity with Arterial Stiffness and Inflammation: Insight from the "Corinthia" Study.
