Slow coronary flow in the presence of normal epicardial coronary arteries frequently has an asymptomatic course; however, some reports have showed its pathologic potential. A 35-year-old male patient was admitted with a history of exertional angina (Canadian class II) of a year duration. During treadmill exercise stress testing, he experienced typical angina pectoris and a 2-mm ST-segment depression. Coronary angiography revealed slow flow in the right coronary artery without any other coronary pathology. Medications with aspirin, nitroglycerin, and a beta-blocker were instituted, after which relief of symptoms was observed. His complaints did not recur during a follow-up period of a year.
