[Radiotherapy and chemotherapy for oncological diseases--unappreciated risk factors for coronary artery disease? Acute coronary syndrome in 3 women after radiotherapy and chemotherapy--case reports].

Chest irradiation and chemotherapy may lead to precocious coronary artery disease due to accelerated atherosclerosis or fibrointimal hyperplasia. Three cases of women (43, 50, and 53 years old) without typical risk factors for cardiac disease admitted to hospital due to acute coronary syndrome are described. Two of them had received chest irradiation and chemotherapy for Hodgkin's disease in the past and the third had been treated with chemotherapy for breast cancer.
