Myocardial infarction occurs: blockage in the heart arteries that causes heart attacks, death of myocardial tissue or blockage of arteries. Congestive heart failure: caused when atherosclerosis or atherosclerosis (mostly atherosclerosis) is so severe that the heart cannot pump very well anymore, this can be disabling because it can cause weakness and difficulty breathing.
