Myocardial ischemia can lead to serious complications, including:

  • Heart attack. If a coronary artery becomes completely blocked, the lack of blood and oxygen can lead to a heart attack that destroys part of the heart muscle. The damage can be serious and sometimes fatal.
  • Irregular heart rhythm (arrhythmia). An abnormal heart rhythm can weaken your heart and may be life-threatening.
  • Heart failure. Myocardial ischemia can damage the heart muscle, reducing its ability to effectively pump blood to the rest of your body. Over time, this damage might lead to heart failure.
