Cardiac infarction, also known as myocardial infarction or heart attack, is a condition in which the blood supply to the heart is suddenly blocked. It can be caused by atherosclerotic plaques blocking a coronary artery, resulting in an acute myocardial infarction. This can lead to chest pain, shortness of breath, heart palpitations, and in some cases, cardiac arrest and death.

Cardiac infarction is often diagnosed through an electrocardiogram (ECG) test, which records the electrical activity of the heart and shows any abnormalities. Other tests such as blood tests, chest X-rays, echocardiograms, and cardiac catheterization may be used to confirm the diagnosis.

The treatment of cardiac infarction depends on the severity of the condition. In mild cases, rest and medications such as aspirin and beta blockers may be prescribed. In more severe cases, a procedure known as angioplasty may be performed, in which a stent is placed in the blocked artery to keep it open. In life-threatening cases, the patient may need to undergo open-heart surgery to restore the blood supply to the heart.

It is important to recognize the symptoms of cardiac infarction and to seek medical help as soon as possible. Prompt medical treatment can help to reduce the risk of long-term complications and death.
