Myocardial Infarction (MI) A myocardial infarction, more commonly known as a heart attack, is caused by a reduction or cessation of blood flow towards a section of the heart muscle, leading to muscular damage.[1] This is usually a result of prolonged cardiac ischemia[2] due to a blockage in one of the coronary arteries.

To reduce the likelihood of this happening, a patient can undergo coronary angioplasty[3], which is when a balloon or stent is inserted into the artery to widen or clear a blocked coronary artery and restore the blood flow to its original rate.

Common symptoms of MI:

  • Dizziness
  • Nausea & vomiting
  • Chest pain (tightness)
  • Pain in left/both arms (pins and needles feeling)
  • Pain in stomach, back and jaw
  • Wheezing/shortness of breath
  • Sweating[4]
