Methods: Totally, 60 patients with CSF were enrolled in this retrospective study and divided into nicorandil group (n = 30) and nitroglycerin group (n = 30). Coronary angiography was administered to intracoronary nitroglycerin or nicorandil 30 seconds later. The coronary blood flow of patients was evaluated by thrombolysis in myocardial infarction (TIMI) frame count (TFC) method. Heart rate, systolic and diastolic blood pressures, and TFCs in left anterior descending artery (LAD), left circumflex artery (LCX), and right coronary artery (RCA) were recorded before and after administration with nicorandil or nitroglycerin. Results: After nitroglycerin administration, systolic and diastolic blood pressures decreased, heart rates significantly increased (P < 0.001). However, systolic and diastolic blood pressures, heart rate had no significant changes after the application of in- tracoronary nicorandil. In addition, after administration with nicorandil or nitroglycerin, TFCs in LAD, LCX, and RCA were significantly decreased (P < 0.001) compared with before administration; however, TFCs recovered to the normal level in the nicorandil group but not nitroglycerin group.
