What causes the heart to get thicker?

What causes the heart to get thicker?

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.

What does a thickening heart 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.

What causes hardening and thickening of the heart muscle?

Hardening and thickening of the heart muscle, known as hypertrophic cardiomyopathy, is often the result of genetic inheritance, according to MedlinePlus. Defects and mutations in the genes that manage heart muscle growth, while inherited, can manifest differently in severity or symptoms across a family.

Can a thickened heart cause sudden cardiac death?

Thickening of the heart muscles is one of the main reasons for sudden cardiac death. Thus, people with this condition should take extra precautions about their overall health and avoid any kind of strenuous activity that puts pressure on their heart muscles.

What happens when the septum of the heart becomes thicker?

In most people with hypertrophic cardiomyopathy, the muscular wall (septum) between the two bottom chambers of the heart (ventricles) becomes thicker than normal. As a result, the thicker wall may block blood flow out of the heart.

What happens to the heart muscle with hypertrophic cardiomyopathy?

Most affected people have a family history of the disease, and some genetic mutations have been linked to hypertrophic cardiomyopathy. Restrictive cardiomyopathy. In this type, the heart muscle becomes rigid and less elastic, so it can’t expand and fill with blood between heartbeats.

What causes hardening of the heart muscle?

The blood vessels of the heart can get hardened due to deposition of plaques along the arteries. These plaques are mainly made up of cholesterol and other fats. The condition is known as atherosclerosis. As the plaques build up they cause the arteries to become narrow and harder decreasing blood flow to the muscles.

What causes a thick heart?

One of the main causes is gene mutation. The mutation causes the heart muscles to grow thick and in some cases develop an abnormal heart muscle fiber arrangement. This causes the heart muscles to get intertwined and lead to a condition called myofiber disarray.

What are symptoms of heart muscle damage?

Damage to the heart muscle may diminish the pumping ability of the heart. If the left side of the heart is damaged by the heart attack, a person may experience fatigue, shortness of breath, low blood pressure and chest pain.

What does thickening of the heart mean?

The thickening of heart wall means that the heart chambers like ventricles have a thicker than normal wall or a hypertrophied wall.
