Calcium antagonists, nicorandil and long-acting nitrates are highly effective for preventing coronary spasm. The withdrawal of coronary vasodilators, especially calcium antagonists, is risky in cases of vasospastic angina. We herein present a case of cardiopulmonary arrest that occurred due to coronary spasm triggered by the discontinuation of coronary vasodilators during the peri-operative period of gastrectomy. Vasospastic angina patients who are not able to take oral coronary vasodilators in the peri-operative period should be maintained on a parenteral vasodilator until they are able to take them orally. Physicians should also be aware of the possible development of nitrate tolerance in patients on prolonged nitrate therapy.
