This is a condition that is causes by a coronary Artery disorder. The factors that contribute to this condition include cigarette smoking, increased cholesterol level and increase in blood pressure. The availability of these factors can contribute to the malfunction of the heart and which will include; abnormal heart rhythms, heart attack and failure. Myocardial infraction is progressive and chronic and this can be caused by blockage of the artery hence resulting to heart attack.
The cause of massive heart attack is basically as a result of death that occurred to some muscles from previous attacks. When a heart attack has occurred, the heart undergoes remodeling which is the response that the muscles undergo. This action leads a stretch to cover the slack from damaged muscles. The stretching results to a contraction of the normal muscles which becomes weak and eventually the condition leads to heart failure hence massive heart attack.
