 Myocardial infarction - Wikipedia, the free encyclopedia
The most important treatment in myocardial infarction is restoring the blood flow to the heart, by thrombolysis (enzymatically dissolving the clot in the artery) and/or angioplasty (using a balloon to push the artery open).
Myocardial rupture is most common three to five days after myocardial infarction, commonly of small degree, but may occur one day to three weeks later, in as many as 10% of all MIs.
Acute myocardial infarction is usually characterized by varying degrees of chest pain, discomfort, weakness, sweating, nausea, vomiting, and arrhythmias, sometimes causing loss of consciousness.

 Myocardial Infarction
The traditional concept that myocardial infarctions can be classified as transmural or nontransmural on the basis of the presence or absence of Q waves is misleading, since autopsy studies have demonstrated convincingly that pathologic Q waves may be associated with nontransmural infarction and may be absent with transmural infarction.

 Myocardial infarction
Acute myocardial infarction (AMI) is the rapid development of myocardial necrosis resulting from a sustained and complete reduction of blood flow to a portion of the myocardium, produced by a superimposed thrombosis, generated by a ruptured atherosclerotic plaque
Infarctions can be divided into Q-wave and non Q-wave, with the former being transmural and associated with totally obstructed infarct-related artery and the latter being non-transmural and associated with patent, but highly narrowed infarct-related artery
After total occlusion myocardial necrosis is complete in 4-6 hours.
