Background Connective tissue disease, which is an inflammatory condition represented by C-reactive protein (CRP), is a risk factor for ischemic heart disease. The aim of the present study was to examine if there is a relationship between connective tissue disease and coronary spastic angina, and whether the inflammatory condition was associated with ischemic heart disease, even in patients with connective tissue disease. Methods and Results The study group comprised 73 consecutive patients with connective tissue disease who were admitted to the Department of Cardiovascular Medicine between April 2000 and March 2003. Of the 73 patients, 38 (19 men, 19 women) were diagnosed as having an ischemic heart disease (7 patients acute coronary syndrome, 19 patients coronary spastic angina, 12 patients stable exertional angina). In the present study, 19 (50.0%) of the 38 patients of ischemic heart disease were diagnosed as having coronary spastic angina. In the same study period, 151 (38.7%) of 390 patients with ischemic heart disease (without connective tissue disease) were diagnosed as having coronary spastic angina. The frequency of the patients with coronary spastic angina tended to be higher in patients with connective tissue disease than in patients without connective tissue disease. Among the study patients, serum CRP concentrations (mg/dl) were higher in patients with acute coronary syndrome (1.50±1.19, n=7) and those with coronary spastic angina (1.06±1.78, n=19) than in those with non-ischemia (0.35±0.40, n=35, p<0.05). Conclusions Coronary spastic angina is a frequent complication in patients with connective tissue disease and the inflammatory condition is associated with coronary spastic angina and unstable angina in patients with connective tissue disease.
