Insights

Severe left ventricular hypertrophy (LVH) affects 7.3% of patients with arterial hypertension (AHT). These patients often have uncontrolled blood pressure despite treatment, highlighting the need for better diagnostic tools.

Area of Science:

  • Cardiology
  • Hypertension Research
  • Diagnostic Imaging

Background:

  • Arterial hypertension (AHT) is a leading global cause of preventable death.
  • Left ventricular hypertrophy (LVH) is a critical prognostic marker in AHT, predicting mortality.
  • Echocardiography is vital for assessing LVH in hypertensive patients.

Purpose of the Study:

  • To determine the prevalence of LVH via echocardiography in AHT patients.
  • To characterize patients with severe LVH.
  • To compare severe LVH patients with those having normal or other forms of LVH.

Main Methods:

  • Retrospective monocentric study at a tertiary hypertension clinic.
  • Analysis of echocardiographic reports to identify LVH.
  • Comparison of severe LVH patients (septum thickness ≥ 15 mm) with normal geometry and other hypertrophy groups based on clinical and demographic factors.

Main Results:

  • Severe LVH was found in 7.3% of 400 AHT patients; 52.5% had abnormal LV geometry.
  • Severe LVH patients were more likely male, older, with uncontrolled BP (especially nocturnal), multiple comorbidities, and on multi-drug therapy.
  • Severe LVH correlated with higher 24-hour mean, awake, and asleep diastolic BP compared to other hypertrophy groups.

Conclusions:

  • Over half of AHT patients exhibit abnormal LV geometry, with 7.3% showing severe LVH.
  • Severe LVH is associated with more frequent uncontrolled AHT, despite intensive treatment.
  • The Sokolow-Lyon index appears insufficient for detecting LVH in AHT.

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...

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...

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...

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

Pathophysiology of Heart Failure

Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...

Mitral Stenosis II: Clinical features and Diagnostic Tests

Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...
