9 hours ago A heart attack, also called a myocardial infarction, happens when a part of the heart muscle doesn’t get enough blood. The more time that passes without treatment to restore blood flow, the greater the damage to the heart muscle. Coronary artery disease (CAD) is the main cause of heart attack. A less common cause is a severe spasm, or sudden

3 hours ago The strongest genetic effect on the risk of myocardial infarction is that of a segment on chromosome 9p21.3 ( 9 ). This risk locus for myocardial infarction has now been replicated in more than 45 000 cases and 85 000 controls. Interestingly, this chromosome region does not contain any gene coding for a protein.
