Left Ventricular Hypertrophy
Left ventricular hypertrophy is an enlargement of muscle tissue
form the walls of the heart pumping chamber (left ventricle). this disorder
common in people whose blood pressure is not controlled
or have other heart conditions.
Left ventricular hypertrophy can occur when one or two factors causing your heart to work harder than usual to pump blood throughout the body. For example, if a person's high blood pressure, left ventricular muscle must contract more forcefully than usual to counter the effects of high blood pressure.
Having to adjust to high blood pressure, muscle tissue in the wall of the left ventricle become dilated, whereas the increase in muscle mass of the heart causing heart function deteriorated.
Factors that can cause the heart to work harder, among others:
- High blood pressure (hypertension)
- Aortic valve stenosis (abnormal narrowing of the aortic valve)
- Hypertrophic cardiomyopathy. (Widening and weakening of the heart muscle)
- Intense athletic training and for a long time
Maybe at first the patient will not experience significant symptoms. But when left ventricular hypertrophy develops and demonstrates complications will display symptoms such as:
- Shortness of breath
- Chest pain, usually after exercise
- The heart is beating fast, irregular, too strong or has abnormal rate (palpitations)
- Dizziness or fainting
- Drugs for high blood pressure such as angiotensin-converting enzyme (ACE) inhibitors, angiotensin II receptor blockers (ARBs), thiazide diuretics, beta blockers and calcium channel blockers - drugs with a sleep apnea machine that provides continuous positive airway pressure (CPAP) when patients sleep
- Surgery to remove or repair the aortic valve
- Cholesterol-lowering drugs
