I23: Certain current complications following acute myocardial infarction
I23.1: Atrial septal defect as current complication following acute myocardial infarction
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.
Various problems can occur after a heart attack.
Inside the heart are 4 chambers. There are two heart atria and two ventricles. Between the atria and the ventricles there is a separating wall made of heart muscle. When the heart muscle does not receive enough blood, the tissue can die off. As a result, a hole has formed between your atria.
The heart may no longer be able to pump the blood through the body so well. They may also lose consciousness as a result.
