Angina was an unreliable predictor of obstructive CAD in aortic stenosis; this Level 3 cohort study leaves open whether routine preoperative angiography improves outcomes.
Does the presence of angina pectoris predict significant coronary arterial obstruction in patients with aortic valve stenosis?
The study demonstrates that angina is an unreliable predictor of coronary artery disease in aortic stenosis, supporting the recommendation for routine pre-operative coronary angiography in patients over 40.
Mandal et al. (1976) studied this question.
