Insights

Left Ventricular Hypertrophy (LVH) affects over half of newly diagnosed hypertension patients. Concentric hypertrophy is the most common LVH geometry, with concentric non-dilated hypertrophy being the predominant phenotype.

Area of Science:

  • Cardiology
  • Hypertension Research
  • Diagnostic Imaging

Background:

  • Left Ventricular Hypertrophy (LVH) is a critical indicator of hypertensive heart disease.
  • Prevalence of LVH in Nigerian hypertensive patients (46%-63%) is notably higher than in Western populations (19%-48%).

Purpose of the Study:

  • To determine the prevalence of LVH in newly diagnosed hypertensive patients.
  • To characterize the patterns of left ventricular (LV) geometry and LVH phenotype in this population.

Main Methods:

  • A cross-sectional, observational study conducted from June 2019 to June 2021.
  • Involved 300 newly diagnosed hypertensive adults and 300 healthy controls.
  • Echocardiography was performed, utilizing American Society of Echocardiography and European Association of Cardiovascular Imaging criteria.

Main Results:

  • 59% of newly diagnosed hypertensive patients exhibited LVH.
  • Concentric LVH was the most prevalent geometry (37%).
  • Concentric non-dilated hypertrophy was the most common LVH phenotype (55.4%).

Conclusions:

  • LVH is highly prevalent in newly diagnosed hypertensive individuals, exceeding 50%.
  • Concentric hypertrophy is the predominant LV geometry.
  • Concentric non-dilated hypertrophy represents the most frequent LVH phenotype.

Cardiomyopathy III: Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

Heart Failure II: Pathophysiology

Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...

Hypertension III: Clinical Manifestations and Diagnostic Studies

Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

Hypertension II: Pathophysiology

Hypertension is a chronic condition in which the blood's force against artery walls is excessively high, posing risks such as heart disease. The condition's underlying mechanisms involve complex interactions among the cardiovascular, kidney, and autonomic nervous systems.Renin-Angiotensin-Aldosterone System (RAAS): This system significantly influences blood pressure regulation. When blood pressure decreases, the kidneys secrete renin. This enzyme transforms angiotensinogen, a plasma protein,...

Hypertension I: Introduction01:28

Hypertension I: Introduction

Hypertension is a widespread, long-term medical condition where blood pressure in the arteries remains elevated. It is characterized by systolic blood pressure readings of 130 mm Hg or above or diastolic blood pressure (DBP) readings of 80 mm Hg or higher. Unmanaged hypertension poses significant health risks, making the distinction between primary (or essential) hypertension and secondary hypertension crucial, as their management and implications vary.Primary HypertensionPrimary hypertension,...

Mitral Regurgitation I: Introduction01:20

Mitral Regurgitation I: Introduction

Mitral regurgitation is characterized by the backward circulation of blood from the left ventricle to the left atrium during systole, a phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. This abnormal flow occurs primarily due to the dysfunction of the mitral valve or its supporting structures, which include the mitral leaflets, chordae tendineae, annulus, and papillary muscles.Etiology and Mechanisms:Primary Mitral Regurgitation: This type arises from...
