Symptoms of Coronary Artery Disease

Coronary artery disease (CAD) is a leading cause of death worldwide. The most serious presentation of coronary heart disease is an abrupt, unexpected cardiac arrest and death due to complete blockage of blood flow to major part of heart. Symptoms of coronary artery disease depend on the severity of artery blockage. Most people think that if someone clutches his chest and falls to the floor, he/she probably has a heart attack, but everyone does not have such a dramatic presentation of coronary heart disease. Many people may just feel unwell or have symptoms such as indigestion when they are actually having symptoms of heart attack or coronary artery disease. Read to know more on symptoms of CAD so that you can recognise the signs and symptoms early.


Cardiac arrest: This usually occurs in people, who have had heart attacks (myocardial infarction) before, but are unaware that it is the presenting symptom of coronary heart disease. It may occur during exercise or activity because the heart muscle's increased demand for nutrients and oxygen is not being met by the blocked coronary blood vessel. Most people may have some symptom or discomfort before a cardiac arrest.


Characteristic symptoms of a coronary heart disease: Classic symptoms of coronary artery disease are:

  • Chest pain on the left side associated with difficulty in breathing or shortness of breath. The pain may vary in characteristic from tightness, fullness, a pressure to an ache.
  • Profuse sweating.
  • Nausea.

Most people, however, do not present in the classical way.


Common symptoms of coronary heart disease

  • Chest pain on physical exertion (such as on climbing stairs, doing exercise etc). The pain may be relieved by rest.The pain may be sharp or more like a pressure, heaviness or tightness in the chest. At times, the pain can come and go or the discomfort may persist.
  • Shortness of breath or difficulty in breathing on exertion.
  • Some people may experience spread of pain to back, shoulders, jaw or arm, especially on the left side either during exertion or at rest.
  • Feeling rapid or strong heartbeats (palpitation).
  • Dizziness, light-headedness or fainting.
  • Unexplained fatigue or tiredness on exertion or at rest.
  • Irregular heartbeat (the heart beat may occasionally stop or it may be very fast).

These are some symptoms of coronary artery disease and a person may or may not have all of the above mentioned symptoms. As the coronary arteries may be blocked 50% or more without causing any significant symptoms it is important to consult a doctor if you have any symptom suggestive of coronary artery disease.
