The appropriateness of use of coronary angiography in New York State
Article Abstract:
A significant number of patients may undergo coronary angiography for uncertain indications, or signs of disease, in New York State. Coronary angiography is a surgical procedure performed on patients with suspected coronary artery disease. Among 1,335 patients who underwent angiography in New York State in 1990, 28% were suffering from unstable angina, 22% were suffering from chronic stable angina and 18% were evaluated during a heart attack. Seventy-six percent of the coronary angiographies were performed for appropriate indications, 20% for uncertain indications and 4% for inappropriate indications. The number of inappropriate procedures varied among different hospitals, but not significantly. The number of inappropriate procedures performed on elderly patients was not higher than the number performed on younger patients.

Appropriate use of carotid endarterectomy
Article Abstract:
Stroke patients facing carotid endarterectomy and their physicians should have access to records of stroke or death within 30 days after surgery in the hospital intended for the surgery. The use carotid endarterectomy after stroke is widely used, and in many cases, dramatically reduces the number of nonfatal strokes over the next two years. But to achieve this, there are degrees of severity ncessary in the patient's condition, such as the obstruction in the blood vessel being more than 70%. The success also depends on the level of skill of the surgeons, and therefore the records should be open.
