Postprandial angina pectoris is associated with severe coronary artery disease.
This study investigated the association between postprandial angina pectoris and the severity of coronary artery disease (CAD). Researchers assigned 408 CAD patients with chest pain and ischemia into 2 groups: the postprandial angina group and the non-postprandial angina cohort (control group). The coronary angiography data of all the patients was examined.
Researchers observed a higher incidence of rest and exertion angina pectoris and more severe CAD in subjects in the postprandial angina group than in those in the control group. In addition, majority of the angina pectoris events experienced by the participants in this study occurred after dinner. The results of this study show that postprandial angina might be a good indicator of the severity of CAD.
