1. Heart Attack or myocardial infarction
A heart attack occurs when a portion of the heart muscle dies due to a lack of oxygen. Symptoms of a heart attack include sudden severe chest pain or pressure, sweating, nausea, shortness of breath, and fainting.
2. Coronary Artery Disease
Coronary artery disease is a condition where plaque builds up inside the arteries that supply blood to the heart muscle. Plaque buildup restricts the flow of oxygen-rich blood to the heart muscle, causing chest pain or discomfort. If left untreated, coronary artery disease may lead to a heart attack.
3. Valvular Heart Disease
Valvular heart disease involves damage to the valves of the heart. A valve is a flap that opens and closes to allow blood to pass through. When a valve does not open properly, blood backs up and forms clots. Clots can block the flow of blood through the heart and cause serious complications.
4. Enlarged Heart
The enlargement of the heart is called cardiomyopathy. Cardiomyopathy causes the heart to become enlarged and stiff. This makes it difficult for the heart to pump blood throughout the body.
5. Congenital Heart Disease
Congenital heart disease refers to any defect in the structure of the heart present at birth. These defects occur before birth and cannot be corrected.
6. Congestive heart failure
Heart muscles are designed to pump blood but sometimes in some physical conditions like aging, kidney failure, or other ailments the heart muscle becomes weak and cannot supply sufficient blood as a result fluid builds up in the lungs and it causes shortness of breath. In severe cases, it can cause sudden cardiac arrest.
7. Electrical Problems in the Heart
Electrical problems in the heart can cause improper signaling and may cause irregular heartbeat, arrhythmia, and cardiac arrest.
