Z03.4: Observation for suspected myocardial infarction

You were medically monitored in order to rule out a heart attack.

The heart muscle is supplied with oxygen-rich blood via the coronary arteries. The coronary arteries are blood vessels that run around the outside of the heart. The coronary arteries can get narrow due to deposits of fat and calcium. Various things favor these deposits. These include smoking, high blood pressure, and other disorders. The porosity of the coronary arteries can also be restricted for other reasons. For example, if the blood vessel wall is damaged or the muscles in the blood vessel wall cramp up. A heart attack involves parts of the heart not getting enough oxygen-rich blood. As a result, the affected heart tissue gets damaged or dies.

Typical symptoms or suspicious examination results may indicate a heart attack. A heart attack can cause pain in the chest or shortness of breath, for example. Other symptoms are also possible with a heart attack. If a heart attack is suspected, other tests or close observation may be required until the suspicion can be ruled out.

  • G: Confirmed diagnosis
  • V: Tentative diagnosis
  • Z: Condition after
  • A: Excluded diagnosis
