What is left ventricular hypertrophy?

Left ventricular hypertrophy (LVH) is a condition in which the walls of the heart’s left ventricle become enlarged and thickened. Since this chamber is the main pump that delivers oxygenated blood to the body, the heart must increase blood pressure to fill the cavity, which over time causes strain on the heart, potentially leading to arrhythmias and heart failure.

This condition is more common in individuals with high blood pressure. Treating hypertension can improve symptoms and, in some cases, may reverse left ventricular hypertrophy.

Possible causes of this heart muscle condition include:

• High blood pressure
• Aortic stenosis
• Consistent, high-intensity exercise routines
• Genetic diseases such as hypertrophic cardiomyopathy
• Amyloidosis
• Risk factors for developing this condition include:
  • Older age
  • Being female
  • Genetic predisposition
  • Overweight or obesity
  • Diabetes

Initially, there may be no symptoms, but over time, typical signs may develop, including:

• Headaches
• Shortness of breath
• Fatigue
• Low energy
• Chest pain, especially after physical activity
• Palpitations
• Dizziness
• Loss of consciousness

Diagnosing left ventricular hypertrophy requires a combination of clinical evaluation, electrocardiogram (ECG), echocardiogram, and imaging studies.

Since symptoms can be non-specific, it’s essential to conduct these tests when clinical suspicion arises. Each test serves a specific purpose:

• Electrocardiogram (ECG): An initial tool for diagnosis. The Sokolow-Lyon index, based on wave amplitude, may indicate LVH if the values are above normal. The Cornell index is another tool, especially used in older or obese patients.
• Transthoracic echocardiogram: Confirms LVH by assessing the thickness of the ventricular wall, presence of ventricular remodeling, and the left ventricular mass index.
• Cardiac magnetic resonance imaging (MRI): Used when echocardiography doesn’t provide enough information, allowing precise measurement of left ventricular mass.
• Other tests: Chest X-rays may show signs of cardiomegaly, and stress tests assess the functional impact of left ventricular hypertrophy.

Treatment for Left Ventricular Hypertrophy

Treatment depends on the underlying cause, but typically includes:

Medications to dilate blood vessels and reduce blood pressure

Calcium channel blockers to relax blood vessel walls

Diuretics

Beta-blockers

If the condition is caused by a narrowed aortic valve, surgical correction may be necessary.
