Mainly atherosclerosis which is a condition also called hardening of the arteries. When 70% of the circulation to the heart is obstructed by plaque and deposits, then the heart does not get enough oxygen. This can cause a heart attack if the person exerts themselves. The other condition called angina pectoris is pain in the heart because of lack of oxygen. If heart muscle cells die due to a lack of oxygen it is called a myocaridial infarction.
