Types of heart diseases

  • Coronary artery disease: It is the most common heart disease and develops when plaque gets formed in the artery that supplies blood to the heart. Due to the formation of plaque, the proper supply of blood is reduced and the heart gets less oxygen and less nutrients. After some time, the muscles of the heart get weak and you may suffer heart failure.
  • Arrhythmia: Here, your heart begins to beat too slowly or too quickly. It is further classified as tachycardia (rapid heartbeat), bradycardia (slow heartbeat) and atrial fibrillation (irregular heartbeat).
  • Heart failure: In this case, your heart doesn’t pump blood properly as per the requirement of the body.
  • Valvular Heart Diseases: Your heart has four valves that shrink and relax to supply blood to different parts of your heart. If some issue occurs in these valves, the flow of blood gets blocked and causes heart disease.
  • Cardiomyopathy: This disease occurs in the muscles of your heart.
  • Congenital Heart Disease: Defects in the heart right from the birth of a person.
