Chronic and intense exercise programs lead to cardiac adaptations, followed by increased left ventricular wall thickness and cavity diameter, at times meeting the criteria for left ventricular hypertrophy (LVH), commonly referred to as "". Recent studies have also reported that extremely vigorous exercise practices have been associated with heightened left ventricular trabeculation extent, fulfilling noncompaction cardiomyopathy criteria, as part of exercise-induced structural adaptation. These changes are specific to the exercise type, intensity, duration, and volume and workload demands imposed on the myocardium.

Article Synopsis
  • * The study involved 5727 adult volunteers, revealing that while 78.7% of those with hypertension were diagnosed, only 48.3% had their condition under control, with women and older individuals showing higher rates of awareness and treatment.
  • * The findings suggest a correlation between hypertension and higher body mass index (BMI), as well as related health issues like diabetes and heart disease, indicating the necessity for widespread screening programs and improved training for healthcare professionals.

Severe acute respiratory syndrome (SARS)-CoV-2 virus disease (coronavirus disease 2019; COVID-19) is associated with increased coagulation activity, resulting in an excessive risk of venous thromboembolism (VTE) and poor prognosis. The most common manifestation of VTE is pulmonary embolism (PE), with approximately one in five hospitalised patients being at risk. These reports led to the empirical use of prophylactic anticoagulation, even in the absence of established or clinically suspected disease.

Article Synopsis
  • - Cardiovascular diseases (CVDs) are the top cause of early deaths worldwide, including in Ukraine, and dyslipidemia is a major risk factor, highlighting the need for early detection and management.
  • - There is a lack of specific guidelines in Ukraine for managing dyslipidemia in individuals with low-to-moderate CVD risk, necessitating the development of structured, easy-to-follow recommendations.
  • - An expert panel in Ukraine has emphasized the role of family physicians in primary prevention through lipid-lowering interventions and suggested the use of nutraceuticals, like red yeast rice, as part of lifestyle changes for effective preventive strategies.

The prevalence of arterial hypertension is high in patients with diabetes mellitus (DM). When DM and hypertension coexist, they constitute a dual cardiovascular threat and should be adequately controlled. Novel antihyperglycemic agents, including sodium-glucose co-transporter 2 (SGLT-2) inhibitors, glucagon-like peptide-1 receptor agonists (GLP-1 RAs), and dipeptidyl peptidase-4 (DPP-4) inhibitors, have recently been used in the treatment of DM.

Sodium glucose cotransporter 2 (SGLT2) inhibitors represent a novel class of oral antihyperglycemic drugs that have been approved over the last decade for the management of type 2 diabetes mellitus. Except the glucose-lowering effects, robust evidence also suggests that SGLT2 inhibitors confer benefits in cardiovascular system. The purpose of this review was to investigate the effects of SGLT2 inhibitors across the spectrum of arterial hypertension.

Blood pressure (BP) is a physiological parameter with short- and long-term variability caused by complex interactions between intrinsic cardiovascular (CV) mechanisms and extrinsic environmental and behavioral factors. Available evidence suggests that not only mean BP values are important, but also BP variability (BPV) might contribute to CV events. Labile hypertension (HTN) is referred to sudden rises in BP and it seems to be linked with unfavorable outcomes.

Background: The impact of overt diabetes and poor glycemic control on the risk of cardiovascular disease is well established. Among patients with type 2 diabetes, several studies demonstrated a significant increase in coronary artery disease-related death and cardiovascular events associated with HbA1c levels of greater than 7% compared with lower levels. Sodium-glucose cotransporter 2 (SGLT-2) inhibitors are a novel class of anti-diabetic drugs that lower blood glucose levels through the suppression of renal glucose reabsorption thereby promoting renal glucose excretion.

Article Synopsis
  • SGLT-2 inhibitors are a new class of oral medications for diabetes, with several already approved for use in various countries and more under development.
  • The study reviews how these drugs work by preventing glucose reabsorption in the kidneys, leading to increased glucose, sodium, water, and uric acid excretion.
  • Understanding the diverse effects of SGLT-2 inhibitors, which act on both the kidneys and other organs, may help in predicting additional benefits and potential side effects of their use.

Arterial hypertension and aortic valve stenosis are common disorders and frequently present as concomitant diseases, especially in elderly patients. The impact of hypertension on heart haemodynamics is substantial, thus affecting the clinical presentation of any coexisting valvulopathy, especially of aortic stenosis. However, the interaction between these 2 entities is not thoroughly discussed in the European or/and American guidelines on the management of hypertension or/and valvular heart disease.

Background: High normal blood pressure (BP; 130-139/85-89 mm Hg) is related with increased cardiovascular (CV) risk compared to normal BP (120-129/80-84 mm Hg) or/and optimal BP (<120/80 mm Hg). Low apelin plasma levels have been associated with arterial hypertension and atherosclerosis, while high visfatin plasma levels may promote vascular inflammation and atherosclerotic plaque destabilization and have been evaluated as a marker for identifying stages of essential hypertension. We sought to compare the apelin and visfatin plasma levels between subjects with high normal BP and subjects with normal or optimal BP matched for age, gender, smoking, and body mass index (BMI).

Intrarenal hemodynamics depend on blood pressure (BP), heart rate (HR), and smoking. Although BP levels have been associated with kidney function, the effect of HR levels, BP, and HR variability on renal function are less well clarified. This cross-sectional study sought to determine the association of 24-hour BP and HR variability with kidney function in hypertensive patients, stratified by smoking.
