MI ussually follows the sudden occlusion of coronary artery & abrupt cessation of blood & Oxygen (O2) flow to the hearth muscle resulting in localized necrotic area in myocardium.

The most common site for Myocardial Infarction is the anterior wall of the left ventricle, another site are posterior and inferior wall of the left ventricle. More then half the deaths case of MI occur during the first and second hours before hospitalized, and Majority of hospital deaths occur during the first 24 hours discharged’s patient.

4. Rehabilitation for Patient Myocardial Infarction
On this stage the goals is how to give health education to the patient with Myocardial Infarction cases by assist the patient to achieve and maintain optimum helath & a productive life within the limitations.
