Why the study?
Does non-invasive assessment (echocardiography, history, exercise test) identify left main or proximal LAD disease in patients with angina pectoris?
Does non-invasive assessment (echocardiography, history, exercise test) identify left main or proximal LAD disease in patients with angina pectoris?
Non-invasive means such as echocardiography, history, and exercise testing are insufficient to reliably predict left main or proximal LAD coronary artery disease.
Noninvasive tests cannot identify LMCA or proximal LAD lesions; leaves open the necessity of angiography in angina.
One hundred consecutive patients with angina pectoris referred for coronary arteriography were studied prospectively for non-invasive assessment of left main (LMCA) or proximal left anterior descending coronary artery (proximal LAD) disease. Evaluation of echocardiographic interventricular septal motion, history and exercise test response could not identify the patients with these specific lesions. It is concluded that LMCA and proximal LAD disease still remain largely unpredictable by non-invasive means.
