This case report describes a 78-year-old man with recurrent angina attacks due to coronary spasm. He was treated with maximum daily doses of antianginal and antioxidative medications, including isosorbide mononitrate (40 mg), diltiazem (200 mg), and tocopherol nicotinate (300 mg). Despite the use of these medications, rest angina occurred 2 or 3 times during sleep. Although his symptoms disappeared promptly with the use of sublingual glycerine trinitrate (GTN), an angiotensin II receptor blocker, valsartan (80 mg), was added on a daily basis with the intent of improving endothelial function and controlling his angina. After beginning 80 mg/day of valsartan, the number of the anginal attacks decreased by about 66%. The anginal attacks totally disappeared after the dose of valsartan was increased to 160 mg/day. To confirm the effect of valsartan on his angina, valsartan was stopped temporarily with his consent. His anginal attacks increased to the same frequency that was observed before valsartan; therefore, valsartan therapy was resumed. The data indicate that the addition of valsartan to maximum antianginal medications may be effective in helping to control angina attacks at rest due to coronary spasm.
