Our heart is a major organ that plays an important role by sending blood throughout the body to deliver nutrients and oxygen.

If a problem develops in the heart, which performs this role, it can also negatively affect your health, and various problems can occur in the heart.

Cardiomegaly literally means that the heart has become abnormally enlarged, and it can be broadly divided into hypertrophic cardiomyopathy and dilated cardiomyopathy.

In the case of hypertrophic cardiomyopathy, it refers to a state in which the heart muscle has thickened, while dilated cardiomyopathy refers to the atria and ventricles becoming enlarged and dilated.

Hypertrophic cardiomyopathy is when part or all of the left ventricle thickens for no apparent reason, and dilated cardiomyopathy is when the left ventricle enlarges and its contractile function declines.

There are various causes of cardiomegaly, including high blood pressure and cardiovascular disease, and excessive alcohol use or drug abuse can also cause symptoms.

When blood pressure rises, the heart is placed under strain and the muscle may enlarge, and vascular disease can also affect cardiomegaly.

Infection can also lead to enlargement of the heart muscle, and because anemia is a condition in which the blood’s oxygen-carrying function is reduced, it can cause the heart to enlarge its muscle to compensate.

In the case of cardiomegaly, it often appears without symptoms at first and does not particularly interfere with daily life, so symptoms may develop without the person even knowing.

If symptoms do appear, you may become short of breath more easily than usual during exercise, or experience difficulty breathing.

In severe cases, difficulty breathing may occur even while resting.

Chest pain may also be present, swelling may develop around the legs or ankles, and fatigue and overall weakness may also be reported.

Because a variety of symptoms can accompany this condition, it is important to get checked and receive appropriate treatment if you have suspicious symptoms.

In most cases, symptoms are managed with diuretics, but the treatment method may vary depending on the underlying cause.

If symptoms of heart failure are present, other medication treatments may be used in addition to diuretics, and if high blood pressure is the main cause, treatment is carried out using antihypertensive medication.

It is also important to make efforts to prevent symptoms in daily life.

It is good to do moderate aerobic exercise regularly, and when eating, you should avoid overly salty food.

It is also advisable to avoid smoking, which can burden the heart and blood vessels, and since alcohol also places strain on the heart muscle, reducing drinking can help prevent symptoms.

Today we looked at the causes and symptoms of cardiomegaly, as well as ways to treat and prevent symptoms. Please refer to the information above and manage your symptoms accordingly.
