What causes a thickened heart muscle?

Hypertrophic cardiomyopathy is usually caused by abnormal genes (gene mutations) that cause the heart muscle to grow abnormally thick. In most people with hypertrophic cardiomyopathy, the muscular wall (septum) between the two bottom chambers of the heart (ventricles) becomes thicker than normal.

How do you treat thickened heart muscle?

Alcohol septal ablation (nonsurgical procedure) – In this procedure, ethanol (a type of alcohol) is injected through a tube into the small artery that supplies blood to the area of heart muscle thickened by HCM. The alcohol causes these cells to die. The thickened tissue shrinks to a more normal size.

Can a thickened heart muscle be reversed?

Treatment. There is no treatment which can reverse the changes of the heart muscle. Treatment aims to ease symptoms if they occur and to prevent complications. If you do not have any symptoms or you only have mild symptoms then you may not need any treatment.

What does heart thickening mean?

Hypertrophic cardiomyopathy (HCM) is a condition in which the heart muscle becomes thick. Often, only one part of the heart is thicker than the other parts. The thickening can make it harder for blood to leave the heart, forcing the heart to work harder to pump blood.

How can I reduce the thickness of my heart wall?

The procedures may include:

  1. Septal Myectomy – Removal of a small amount of thickened septal wall to remove the blockage in the passage of blood.
  2. Ethanol Ablation – Cardiac catheterization procedure is carried out in which pure alcohol is used to kill the cells, leading to the walls shrinking back to normal size.

What are 4 signs of cardiomyopathy?

Signs and symptoms of cardiomyopathy include:

  • Shortness of breath or trouble breathing, especially with physical exertion.
  • Fatigue.
  • Swelling in the ankles, feet, legs, abdomen and veins in the neck.
  • Dizziness.
  • Lightheadedness.
  • Fainting during physical activity.
  • Arrhythmias (irregular heartbeats)

How serious is thickening of the heart?

The thickened heart muscle can eventually become too stiff to effectively fill the heart with blood. As a result, your heart can’t pump enough blood to meet your body’s needs. Sudden cardiac death. Rarely, hypertrophic cardiomyopathy can cause heart-related sudden death in people of all ages.

Can high blood pressure cause thickening of the heart?

High blood pressure means the pressure inside the blood vessels (called arteries) is too high. As the heart pumps against this pressure, it must work harder. Over time, this causes the heart muscle to thicken. Because there are often no symptoms with high blood pressure, people can have the problem without knowing it.

Can you live a long life with hypertrophic cardiomyopathy?

Research has shown that with proper treatment and follow-ups, most people with HCM live a normal life. A database of 1,297 patients with HCM from the Minneapolis Heart Institute Foundation identified that 2% of the patients can live past 90 years, and 69% of them were women.

What medications should be avoided with hypertrophic cardiomyopathy?

Agents to reduce pre- or afterload (such as nitrate, ACE inhibitors, nifedipine-type calcium antagonists) are contraindicated with HOCM due to possible aggravation of the outflow tract obstruction. This often impedes therapy of coexistent arterial hypertension.

How does hypertrophic cardiomyopathy cause sudden death?

When patients complain of symptoms, these include: dyspnea, dizziness, syncope and angina. HCM can lead to sudden cardiac death (SCD), mainly due to ventricular tachyarrhythmia or ventricular tachycardia. High-risk patients benefit from implantable cardioverter-defibrillators.

Can stress cause hypertrophic cardiomyopathy?

According to a new study, researchers have found that in addition to gene mutations, environmental stress also plays a key role in the development of the heart disease, hypertrophic cardiomyopathy.

Can you reverse heart muscle damage?

Until recently, it was believed that the human heart didn’t have this capacity. But the heart does have some ability to make new muscle and possibly repair itself. The rate of regeneration is so slow, though, that it can’t fix the kind of damage caused by a heart attack.

Can I exercise with left ventricular hypertrophy?

Conclusions: In hypertensive athletes LVH due to hypertension can be reduced and LV-function can be improved by long-term antihypertensive medication despite regular aerobic exercise. Therefore, exercise does not interfere with the regression of LVH on account of antihypertensive therapy in hypertensive subjects.

Does heart wall thicken with age?

The chambers of your heart may increase in size. The heart wall thickens, so the amount of blood that a chamber can hold may decrease despite the increased overall heart size. The heart may fill more slowly.

At what age does hypertrophic cardiomyopathy develop?

Around half of the adults with this condition develop symptoms. The condition progresses as an increasing thickness of the heart muscles. The diagnosis may be done anytime from birth to ages 80 and beyond. The average age for the diagnosis of hypertrophic cardiomyopathy is around 39 years.
