What is an infarct?

Infarct is an ischemic necrosis of the myocardis, which comes as a consequence of the acute insufficiency of the coronary arteries. This comes as a consequence of the obstruction of coronary muscle blood vessels by a thrombus.

It could also come as a consequence of the inside of the blood vessel severing into the lumen of the vessel, thus obstructing it. An infarct manifests with severe prolonged pain, at times shocking. As the thrombus forms, atherosclerosis of blood vessels plays a crucial role as a negative factor.

After the aforementioned examinations, other laboratory tests are recommended such as biological tests:

  • Creatinephosphokinases test, (appears in the 2-3rd hour after an infarction, and reaches a maximum after 6 hrs).
  • Myoglobin test (1-4 hr, reaches peak after a maximum of 12 hours after the infarction).
  • Troponin test (Around the 3rd hour, remains elevated for approximately 10 hours).
  • Lacticodehydrogenase test (Elevates 24 to 48 hours after an infarction, reaches peak elevation 6 days after).
  • Hyperleucocytosis test (2-4 days, remains elevated for up to 2 weeks).
  • Increased sedimentation.
  • Cardiac echo which aids in evaluating the functioning of the left ventricle.
