Types of Heart Diseases

Heart disease is a broad term that includes all types of diseases affecting different components of the heart. Heart means 'cardio.' Therefore, all heart diseases belong to the category of cardiovascular diseases. In the world, India has one of the highest numbers of cases related to heart diseases. According to the California-based CADI (Coronary Artery Disease among Asian Indians) Research Foundation, India will have 62 million heart patients by 2015.

The most common cause of all heart diseases is the inadequate pumping of blood and oxygen from the heart to the rest of the body and vice-versa.

Some types of heart diseases are:
Coronary heart disease (CHD) - Also known as coronary artery disease, it is the most common type of heart disease across the world. It is a condition in which plaque deposits block the coronary blood vessels leading to a reduced supply of blood and oxygen to the heart.

Angina pectoris - It is a medical term for chest pain that occurs due to insufficient supply of blood to the heart. Also known as angina, it is a warning signal for heart attack. The chest pain is at intervals ranging for few seconds or minutes. Based on the causes and risk factors, angina is of different types.

Congestive heart failure - It is a condition where the heart cannot pump enough blood to the rest of the body. It is commonly known as heart failure.

Cardiomyopathy - It is the weakening of the heart muscle or a change in the structure of the muscle due to inadequate heart pumping. Some of the common causes of cardiomyopathy are hypertension, alcohol consumption, viral infections, and genetic defects.

Congenital heart disease - Also known as congenital heart defect, it refers to the formation of an abnormal heart due to a defect in the structure of the heart or its functioning. It is also a type of congenital disease that children are born with.

Arrhythmias - It is associated with a disorder in the rhythmic movement of the heartbeat. The heartbeat can be slow, fast, or irregular. These abnormal heartbeats are caused by a short circuit in the heart's electrical system.

Myocarditis - It is an inflammation of the heart muscle usually caused by viral, fungal, and bacterial infections affecting the heart. It is an uncommon disease with few symptoms like joins pain, leg swelling or fever that cannot be directly related to the heart.
