Coronary Artery Disease
Coronary artery disease (CAD) is when your heart arteries become narrowed by a gradual build-up of fatty material within their walls. In time, your arteries may become so narrow that they cannot deliver enough oxygen-rich blood to your heart.
The pain and discomfort you may feel as a result is called angina. If a piece of plaque breaks off it may cause a blood clot (blockage) to form. If it blocks your heart artery and cuts off the supply of oxygen-rich blood to your heart muscle, your heart may become permanently damaged. This is known as a heart attack.
Symptoms of Coronary Artery Disease
- Angina (chest pain or discomfort): chest pain, pressure, tightness, heaviness, squeezing, crushing or burning sensation by emotional stress or physical exertion and relieved by rest.
- Heart Failure: Shortness of Breath.
- Heart Attack: Persistent chest pain that is not relieved by rest or anti-anginal medications (such as Nitroglycerin or Metoprolol). People may experience chest pain, pressure, tightness, heaviness, squeezing, crushing, burning or stomach indigestion sensation, sometimes radiating to neck or any side of the arm, occasionally accompanied with cold sweat, lightheadedness or nausea.
