A heart attack is damage to the heart due to decreasing blood supply (and the oxygen supply) to the part of the heart muscle. A heart attack affects cardiovascular system, this part of the system that shows these effects is the hear muscle.

Arrhythmias: This is a condition in which the heart beats with an irregular or abnormal rhythm.
Cardiogenic shock: Cardiogenic shock is when the heart has been damaged so much that it is unable to supply enough blood to the organs of the body.
Heart rupture: Also known a Myocardial rupture is a tearing of the walls of the ventricles or atria of the heart, of the interatrial or interventricular septum, of the papillary muscles or chordae tendineae or of one of the valves of the heart.
Congestive heart failure: This is the inability to pump enough blood to avoid congestion in the tissues
