  • Blood tests
  • Coronary angiogram
  • Echocardiogram
  • Myocardial perfusion imaging
  • Computerized tomography (CT) angiogram
  • Stress test


  • Clot busters help break up a blood clot that's blocking an artery. These drugs also are known as thrombolytics.
  • Nitroglycerin improves blood flow by temporarily widening blood vessels.
  • Anti-platelet drugs help prevent blood clots from forming.  
  • Statins lower the amount of cholesterol in the blood.
  • Cardiac catheterization to diagnosis and remove blockage
