This heart damage may not be obvious, low blood pressure after stent procedure, or it may cause severe or long-lasting problems. Figure A is an overview of a heart and coronary artery showing damage reconstrution after breast cancer heart muscle caused by a heart attack.
Figure B is a cross-section of the coronary artery with plaque buildup and a blood clot. A less common cause of heart attack is a severe spasm tightening of a coronary artery. The spasm cuts off blood flow through the artery. Heart attacks can be associated with or lead to severe health problems, such as heart failure and life-threatening arrhythmias.
