Why is hypertrophy bad
Many individuals develop heart failure, specifically heart failure with preserved ejection fraction HFpEF, also called diastolic heart failure. Such hearts contract normally, but are too stiff to refill properly.
The diagnosis is easily missed because the heart looks normal when imaged on echocardiography echo. It takes an astute cardiologist to match the symptoms with the potential diagnosis. This may require taking medications for atrial fibrillation or blood pressure, treating sleep apnea , following a low-salt diet and limiting fluid intake.
If amyloidosis is suspected, you should be seen at a specialized amyloid center like the one at Cleveland Clinic to determine the type of amyloid and exclude other reasons that LV hypertrophy may be present. Our expert explains why an enlarged or thickened heart called left-ventricular hypertrophy needs to be investigated by a specialist.

Left ventricular hypertrophy is enlargement and thickening hypertrophy of the walls of your heart's main pumping chamber left ventricle. The thickened heart wall loses elasticity, leading to increased pressure to allow the heart to fill its pumping chamber to send blood to the rest of the body.
Eventually, the heart may fail to pump with as much force as needed. Left ventricular hypertrophy is more common in people who have uncontrolled high blood pressure. But no matter what your blood pressure is, developing left ventricular hypertrophy puts you at higher risk of congestive heart failure and irregular heart rhythms. If left ventricular hypertrophy is caused by high blood pressure, treating high blood pressure can help ease your symptoms and may reverse left ventricular hypertrophy.
Left ventricular hypertrophy usually develops gradually. You may experience no signs or symptoms, especially during the early stages of the condition. If you experience mild shortness of breath or other symptoms, such as palpitations, see your doctor.
If you have high blood pressure or another condition that increases your risk of left ventricular hypertrophy, your doctor is likely to recommend regular appointments to monitor your heart.
Left ventricular hypertrophy has several causes — one is an increase in the size of heart muscle cells and the other is abnormal tissue around the heart muscle cells. Your heart muscle cells may get larger in response to some factor that causes the left ventricle to work harder, such as high blood pressure or a heart condition. As the left ventricle's workload increases, the muscle tissue in the chamber wall thickens.
Sometimes, the size of the chamber itself also increases. Left ventricular hypertrophy may also develop due to problems in the structure of the heart muscle cell. These changes can be related to a genetic defect. Abnormal tissue around the heart muscle cells is a result of several rare conditions. Abnormalities in heart muscle cell structure that result in increased heart wall thickness include:. In addition to hypertension and aortic valve stenosis, factors that increase your risk of left ventricular hypertrophy include:.
Left ventricular hypertrophy changes the structure and working of the heart. The enlarged left ventricle can:. The best way to prevent left ventricular hypertrophy caused by high blood pressure is to maintain healthy blood pressure. To better manage your blood pressure:.

Be sure to speak with your physician, physical therapist , or personal trainer before starting any exercise for muscle growth or hypertrophy. Muscle growth is good.
It signifies that you are getting stronger and exercising regularly. But hypertrophy can also be considered abnormal. Sometimes your heart may become abnormally hypertrophied. This is called cardiac hypertrophy or left ventricular hypertrophy LVH. Causes of LVH may include:. Essentially, these problems cause your heart to work hard to continue to pump blood throughout your body each day.
Symptoms of cardiac hypertrophy may include:. If you have any of these symptoms or suspect any problems with your heart, see your physician right away. They can assess your condition and form a proper diagnosis, leading to the right treatment for you. Pathological conditions involving skeletal muscle hypertrophy are very rare. One condition, called myostatin-related muscle hypertrophy, is a genetic disease characterized by low body fat and muscle hypertrophy.
This condition is rare and typically doesn't cause other problems or impairments. Muscle hypertrophy is the growth of individual muscle cells.
This causes your muscles to grow bigger in response to exercise, especially high-intensity weight training. Most of the time, muscle hypertrophy is a good thing; it signals that your muscles are growing normally or responding normally to resistance-training exercise.
Occasionally, hypertrophy can be harmful, especially in diseases of the cardiac muscle tissue. Understanding how muscle hypertrophy works can help you decide on the best way to increase your muscle size and improve your overall muscular performance.
