The frequency of subjective cardiac and psychological complaints among men and women a year after a confirmed diagnosis of myocardial infarction (MI) were compared. Among 660 survivors, 595 patients completed mailed questionnaires at home one year after the MI. There were 421 men, mean age 67.1 +/- 10.7 years, and 174 women, mean age 72.1 +/- 10.6 years. Controlling for the significantly higher mean age among the women, the latter more often had a previous history of angina pectoris, 54.6% (P < or = 0.05) versus 42.9%, and heart failure, 24.7% versus 13.5% (P < or = 0.01). Despite these facts, the women were significantly less often referred to CCU, 82.2% versus 91.7% (P < or = 0.05). One year after the MI, controlling for differences in age and co-morbidity, women reported significantly higher frequencies of psychological and psychosomatic complaints, including sleep disturbances. These differences may have clinical implications for diagnosis and treatment of women with coronary heart disease.
