Abstract
BACKGROUND: Japanese Circulation Society (JCS) guidelines do not include adolescents with coronary artery spasm.Methods and Results: We recruited 18 adolescents less than 20 years old with vasospastic angina (VSA): 11 were Japanese and 3 had chest symptoms for >12 months before admission. ST-segment elevation was observed in 11 patients and none of the 18 patients had a fixed stenosis. Spasm provocation tests were performed in 9 patients and two-thirds had multiple spasms; 6 suffered from acute myocardial infarction and ventricular fibrillation occurred in 2 patients; 1 patient died and the remaining 17 patents survived. CONCLUSIONS: Clinical status of adolescents with VSA was as severe as in adults with refractory VSA. Cardiologists should cooperate with pediatricians to diagnose and treat adolescents with VSA. There is a need to establish the additional issues for adolescents with coronary spasm in the JCS guidelines.
