Risk factors associated with coronary artery stenosis among patients with chest pain in eastern Taiwan

To analyze the risk factors for coronary artery stenosis among patients who were admitted to the hospital with chest pain in eastern Taiwan, we retrospectively reviewed the clinical data of 444 patients who received coronary arteriography, including 62 aborigines. Results indicated that there were 268 patients (64%) with coronary stenosis. Male to female ratio, mean age, pack-years of cigarette smoking, and hypertension were significantly higher in patients with coronary stenosis (CS group) than in patients without coronary stenosis (control group). There were also significant differences in the serum levels of total cholesterol, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol between the CS and control groups. The total cholesterol and low-density lipoprotein cholesterol of both the CS and control groups were lower than those reported in western Taiwan. The prevalence of coronary stenosis among Taiwanese patients who presented with chest pain was significantly higher than in aborigines (64% vs 38%), although there were no significant differences in common risk factors between these two ethnic groups. These results revealed that the common risk factors in eastern Taiwan were the same as those reported here and suggest that race may be an important risk factor for coronary stenosis.
