Almost every medical advance raises issues that demand creative problem-solving. Take artery-opening angioplasty. It uses a tiny balloon to flatten a cholesterol-filled plaque, restoring blood flow through a narrowed or blocked coronary artery without open-heart surgery. A wire-mesh stent is usually left behind to hold open the artery. However, blood clots sometimes form on a stent. This can block blood flow through the artery, causing a heart attack or sudden cardiac arrest. Taking a drug called clopidogrel (Plavix) with aspirin can fight this problem.
