Methods Of 587 consecutive patients hospitalized with TA from 1998 to 2011, those found to have > 50% reduction of diameter of coronary artery by angiography were recruited. We defined the first finding of coronary involvement as baseline. The clinical features, laboratory data, coronary angiographic findings, treatment, and followup outcomes were summarized retrospectively. Results A total of 45 (7.7%, 45/587) patients with coronary involvement were identified, including 40 with typical angina, and 15 with myocardial infarction. Some had complications such as peripheral vascular murmur, pulseless disease, and hypertension. The average age at onset of cardiac symptoms was 40.3 ± 12.8 years (range 15–64) and 36 were female. At admission, erythrocyte sedimentation rates were elevated in 27 patients (60%) and C-reactive protein levels in 23 (51.1%). The ostia (37.4%) and proximal segments (33.3%) of coronary artery were most frequently involved. The treatment was stent implantation in 10 patients and coronary artery bypass grafting in 13. One female patient suffered sudden death during the angiography. During a mean followup of 5.8 ± 4.5 years, 8 patients died. Conclusion Coronary artery involvement in TA that leads to cardiovascular events, especially to cardiovascular death, is not rare. Early diagnosis and therapy should be emphasized. ER -
