Insights

Vascular Endothelial Growth Factor (VEGF) is elevated in hypertrophic cardiomyopathy (HCM) patients. Higher VEGF levels correlate with significant structural and functional changes, suggesting its potential as a diagnostic marker for HCM.

Area of Science:

  • Cardiology
  • Molecular Biology

Background:

  • Hypertrophic cardiomyopathy (HCM) is a primary genetic heart muscle disease characterized by myocardial hypertrophy.
  • Vascular Endothelial Growth Factor (VEGF) plays a crucial role in myocyte function, growth, and survival.

Purpose of the Study:

  • To investigate the clinical significance of VEGF in relation to structural and functional alterations in patients diagnosed with HCM.

Main Methods:

  • Serum VEGF levels were measured in 21 patients with nonobstructive HCM and compared to healthy controls.
  • Associations between VEGF levels and morphological/functional parameters were analyzed using correlation coefficients.

Main Results:

  • Serum VEGF was significantly elevated in HCM patients (199 ng/L) compared to controls (20 ng/L), P < 0.001.
  • VEGF levels showed significant correlations with left atrium diameter (r=0.51), left ventricle ejection fraction (r=-0.56), left ventricular mass (r=0.61), inferior vena cava diameter (r=0.65), and tricuspid regurgitation (r=0.46).

Conclusions:

  • Elevated VEGF levels are linked to specific structural and functional changes observed in HCM patients.
  • VEGF may serve as a valuable biomarker in the diagnostic evaluation of hypertrophic cardiomyopathy.

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...

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...

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

Pathophysiology of Heart Failure01:17

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...
