Know how heart attack occurs

Coronary artery disease (CAD) affects the arteries that supply blood to the heart. It occurs when the passageway through the coronary arteries, or heart arteries, becomes narrowed by a build-up of plaque, including cholesterol, fatty deposits, calcium, and other substances. The narrowing of arteries results in reduced flow of blood. This leads to a heart attack.

Symptoms of heart attack

CAD reduces blood flow, which means less oxygen is getting to the heart. This may cause mild to severe chest pain, called angina. This pain can spread to the arms or jaw. Other symptoms are: chest pain with dizziness, palpitations and diaphoresis (excessive sweating, "cold sweat"). If the flow of blood in a heart artery is blocked, a heart attack can occur. Anyone who experiences chest pain or signs of a heart attack should seek medical help as soon as possible.

The above are the general symptoms of a heart attack in the majority of patients and should not be treated as a comprehensive list of symptoms. The actual symptoms may vary from one person to another.

Diagnosis of Coronary Artery Disease

There are a number of ways that doctors can diagnose Coronary Artiary Disease.

  • An electrocardiogram, also known as an ECG or EKG.
  • A stress test, also called an exercise stress test, shows how your hear works during physical activity. 
  • A coronary angiogram can show if any blockage and/or narrowing has occurred.

This list is not comprehensive - there could be other tests like nuclear imaging, blood tests etc.

They are used in the treatment of CAD.
