Coronary Artery Diseases

Coronary Artery Disease (CAD)

Fatty deposits or plaque that builds up within the artery walls is called atherosclerosis, or Coronary Artery Disease (CAD). Over time, the deposits harden, thereby narrowing the passageway inside the blood vessel. The narrowed artery limits or obstructs the flow of blood to the heart muscle. The rough, hardened surface of the artery also encourages small blood clots to form.

Over time, CAD weakens the heart muscle and lead to heart failure and arrhythmias. Heart failure is a condition in which the heart can’t pump enough blood throughout the body. Arrhythmias are problems with the speed or rhythm of the heartbeat.

Common Symptoms of CAD

  • Pain, tightness, heaviness or pressure in the chest.
  • Chest pain that spreads to the neck, shoulders, arms, back or jaw.
  • Chest discomfort including shortness of breath, lightheadedness, nausea or vomiting, and sweating.

Less common signs include:

  • Unusual chest pain, or stomach or abdominal pain.
  • Nausea or dizziness.
  • Shortness of breath and difficulty in breathing
  • Anxiety, weakness or fatigue.
  • A fast or fluttering heartbeat, cold sweat or paleness.

You do not have to have all these signs in order to have CAD.
