Left ventricular hypertrophy (LVH): causes, danger and treatment

Other names: Гипертрофия левого желудочка, ГЛЖ, утолщение стенки левого желудочка, гипертрофия миокарда, гипертрофия ЛЖ на ЭКГ, увеличение левого желудочка сердца

Left ventricular hypertrophy (LVH) is a thickening of the walls of the main pumping chamber of the heart, which develops as a response to prolonged increased load. Most often it is caused by arterial hypertension: the heart has to push blood against high pressure for years, and the muscle builds up mass. Other causes include narrowing of the aortic valve, hypertrophic cardiomyopathy, storage diseases, and in athletes, adaptation to training. At first, hypertrophy helps the heart cope, but over time, the thickened muscle becomes stiff, relaxes less well, and is less well supplied with blood. This increases the risk of heart failure, arrhythmias, heart attack and stroke. The good news is that with stable blood pressure control, hypertrophy can decrease.

What is left ventricular hypertrophy

The left ventricle pumps blood to the aorta and further to all organs. When the load on it is increased for a long time, myocardial cells increase in size and the walls become thicker. Doctors distinguish between concentric hypertrophy, in which the walls thicken, but the cavity does not expand - it is typical for hypertension and aortic stenosis, and eccentric, in which both the mass and volume of the chamber increase. A separate group is hypertrophic cardiomyopathy, a hereditary disease in which the muscle thickens without an external cause. The athletic heart is characterized by moderate reversible hypertrophy.

Causes and risk factors

The most common cause is long-term arterial hypertension, especially poorly controlled. Hypertrophy is also caused by aortic stenosis, in which blood passes through a narrowed opening of the valve, and coarctation of the aorta. Its development is promoted by obesity, diabetes mellitus, chronic kidney disease, and obstructive sleep apnea syndrome. Hypertrophic cardiomyopathy is inherited, so when it is detected, relatives are examined. Less commonly, wall thickening is associated with storage diseases such as amyloidosis or Fabry disease. In athletes, hypertrophy is moderate and decreases after stopping training.

Symptoms

For a long time, hypertrophy does not cause any sensations and is detected only on an ECG or ultrasound of the heart. As the thickened muscle progresses, it becomes less relaxed and filled with blood, which causes shortness of breath during exertion and fatigue. The muscle lacks oxygen, which can manifest as pressing pain in the chest even with normal coronary arteries. Interruptions and palpitations occur, and the risk of atrial fibrillation increases. Dizziness and fainting during exercise are characteristic of aortic stenosis and obstructive cardiomyopathy and require urgent examination.

Diagnostics

An ECG allows one to suspect hypertrophy, but may miss it or, conversely, give false signs. The main method is echocardiography: it measures wall thickness, myocardial mass, cavity sizes, evaluates the function of relaxation and contraction, and the condition of the aortic valve. 24-hour blood pressure monitoring shows how well your hypertension is controlled. Blood and urine tests evaluate kidney function and other risk factors. If cardiomyopathy or storage disease is suspected, cardiac MRI, Holter monitoring, genetic testing and consultations with specialized specialists are prescribed.

Treatment and prevention

Treatment is aimed at the cause of hypertrophy. With arterial hypertension, the main thing is to consistently maintain blood pressure in the target range; Some groups of antihypertensive drugs are particularly effective in reducing myocardial mass. The selection of medications is carried out by a cardiologist. In cases of severe aortic stenosis, valve replacement is performed surgically or transcatheterly. Hypertrophic cardiomyopathy is treated using special regimens, sometimes with surgery or implantation of a defibrillator. Changing your lifestyle - losing weight, limiting salt, quitting smoking and alcohol, treating sleep apnea - enhances the effect of therapy.

Regular blood pressure monitoring
Daily intake of prescribed medications
Limiting salt
Losing excess weight
Quitting smoking and alcohol
Moderate aerobic activity after consulting a doctor
Repeated echocardiography on the recommendation of a cardiologist

Frequently asked questions: Left ventricular hypertrophy

Is left ventricular hypertrophy dangerous?+

Yes, LVH is considered an important sign of cardiac damage. It increases the risk of heart failure, atrial fibrillation, heart attack and stroke. However, with timely treatment of the cause, primarily hypertension, the risk is reduced, and the thickening of the walls may decrease.

Can left ventricular hypertrophy go away?+

With hypertension and stable blood pressure control, myocardial mass gradually decreases, usually over months to years. After valve replacement for aortic stenosis, hypertrophy also regresses. In athletes, it decreases after reducing loads. In hereditary cardiomyopathy, the thickening usually persists.

Is it possible to exercise if you have LVH?+

It all depends on the reason. For hypertensive hypertrophy, moderate aerobic exercise at controlled pressure is usually beneficial. In hypertrophic cardiomyopathy and severe aortic stenosis, intense exercise can be dangerous. The acceptable level of activity is determined by the cardiologist after examination.

Is hypertrophy on an ECG an accurate diagnosis?+

No. The ECG gives only indirect signs, which occur in thin young people and athletes without real hypertrophy, and, conversely, may be absent with thickened walls. Confirmation requires echocardiography, which accurately measures wall thickness and myocardial mass.

How is hypertrophy different from cardiomyopathy?+

Left ventricular hypertrophy describes thickening of the walls, most often caused by hypertension or valve disease. Hypertrophic cardiomyopathy is an independent hereditary disease of the heart muscle. Echocardiography, cardiac MRI, family history and genetic testing help distinguish them.
