Correlation between risk factors of coronary artery disease and severity of coronary artery disease

Objective To investigate the clinical characteristics of coronary heart disease risk factors, and explore the relationship of severity of coronary artery lesions in patients with coronary heart disease and coronary heart disease risk factors. Methods In our hospital for treatment of coronary artery disease patients during April 2013 to August 2014, 230 cases of hospitalized patients were divided into two groups after coronary angiography diagnosis, including 170 cases of patients with coronary heart disease as the observation group, and 60 patients with coronary atherosclerosis as the control group with the degree of stenosis less than 50%. The clinical data of two groups were used to study the risk factors for coronary heart disease. The relationship was analyzed between severity of coronary artery pathological changes and coronary heart disease risk factors. Results For the observation group, type 2 diabetes, smoking, and men were associated with coronary heart disease (CHD), with the corresponding OR (95% CI) of 17.489 (11.013-30.017), 48.632 (20.379-117.178), and 18.976 (13.105-28.331), respectively. Smoking and type 2 diabetes were associated with coronary artery stenosis degree (P<0.05), with OR 95% (CI) of 10.15 (2.012-2.584), and of 7.23 (1.613-2.176). The results found there was no relationship among hypertension, dyslipidemia, coronary heart disease (CHD), and age. There was a link between the body mass index (BMI) and the severity of the disease. For observation group, left ventricular ejection function, high-sensitivity C-reactive protein (hs-CRP), and Ccr were related to the severity of coronary lesions, and the patients existed lower Ccr, left ventricular ejection function abate, and increased hs-CRP levels increase, P<0.05, and the OR (95% CI) were 1.986 (5.204-17.627), 1.103 (1.012-1.027), and 2.131 (1.901-2.369). Conclusions Type 2 diabetes, smoking, male patients with coronary heart disease risk factors had a close relationship, and the severity of coronary artery lesions included the reduced renal function in patients and the increased hs-CRP level.
