Its Role in the Management of the Patient with Angina Pectoris
The history, technic, and complications of coronary angiography have been discussed. Myocardial infarction caused by the procedure occurs in 0.3-0.9% of all cases. Two leading groups report an incidence of 1/1000 to 1/2500 deaths related to the procedure. Angiographic anatomy has been described. Indications for the procedure are: intractable angina in patients with or without a history of myocardial infarction and unexplained left ventricular failure or failure due to a left ventricular aneurysm. Among the debatable indications are: unexplained ECG changes, aortic valve disease, preinfarction patterns, cardiogenic shock, and follow-up angiograms after bypass surgery. If immediate surgery is not contemplated, left ventricular failure and a recent myocardial infarction are contraindication to the procedure. The limitations of the procedure are the radiographic resolution and the inconsistent anatomic pattern of minor vessels.
