Heart Attack (Myocardial Infarction)

Heart Attack (Myocardial Infarction) - Symptoms


Signs and symptoms

During a heart attack, a person usually experiences severe central chest pain, classically described as heavy or crushing sensation. The chest pain is very similar to angina pain but it is more prolonged (more than 30 mins) and not relieved with rest or usual medications for angina. This condition is usually accompanied by nausea, sweating and apprehension. However, 25% of heart attacks are clinically silent.

The symptoms of a heart attack include:
  • Sudden onset of severe chest pain or discomfort lasting longer than 15 minutes
  • Sudden onset of shortness of breath, with or without chest pain
  • New onset of chest pain or discomfort at rest or with minimal exertion
  • Cold sweat, nausea or lightheadedness typically associated with chest pain/discomfort or shortness of breath
