Clinical risk stratification correlates with the angiographic extent of coronary artery disease in unstable angina.
OBJECTIVES We sought to determine whether clinical risk stratification correlates with the angiographic extent of coronary artery disease (CAD) in patient with unstable angina. BACKGROUND The Agency for Health Care Policy and Research (AHCPR) guidelines stratify patients with unstable angina according to short-term risk of myocardial infarction or death. Whether these guidelines are useful in...
متن کاملQuantitative angiographic morphology of coronary stenoses leading to myocardial infarction or unstable angina.
Identification of a characteristic morphology of a coronary stenosis likely to result in myocardial infarction would facilitate the prospective evaluation of infarct prevention strategies and identification of high-risk patients. We postulated that coronary lesions associated with recent myocardial infarction or unstable angina would have an angiographic morphology suggesting disruption of an a...
متن کاملCoronary artery fistula presenting as unstable angina.
c t a A 74-year-old man, with a history of heavy smoking, presented with unstable angina (Figure 1). Dobutamine stress echocardiography showed ischemia in the right coronary artery territory. Coronary angiography revealed no obstructive epicardial disease in the left dominant circulation (Figure 2A); the right coronary artery (RCA) was a small caliber and tortuous vessel, with only minor athero...
متن کامل[Dual coronary artery fistulas as a cause of unstable angina].
Coronary artery fistulas are a rare congenital coronary anomaly. Although often small and diagnosed by chance, they can cause a wide range of symptoms associated with myocardial ischemia, including sudden death. We present the case of a 63-year-old woman with cardiovascular risk factors of overweight, smoking, and high blood pressure. For several years, following moderate effort the patient had...
متن کاملUNSTABLE ANGINA Coronary angioplasty for early postinfarction unstable angina
Coronary angioplasty was performed in 53 patients in whom unstable angina had reoccurred after 48 hr and within 30 days after sustained myocardial infarction. Single-vessel disease was present in 64% of the patients and multivessel disease in 36%. The preceding myocardial infarction had been small to moderate in size in the majority of the patients. The left ventricular ejection fraction was mo...
