Is the atherogenic index of plasma associated with the presence of coronary heart disease in Chinese patients?
The atherogenic index of plasma is independently associated with angiographically confirmed coronary heart disease in Chinese men, particularly those with multi-vessel disease, but not in women.
Few studies has investigated the interrelationship between Atherogenic index of plasma (AIP) and coronary heart disease (CHD) especially in Asians. AIP is the logarithmically transformed ratio of triglyceride (TG) to high-density lipoprotein cholesterol (HDL-C), and is thought to be associated with arteriosclerosis, hypertension, diabetes and cardiovascular diseases. Of the 463 patients from Central Hospital of Nanchong in 2011-2014 diagnosed with angiograms, 229 CHD (>50% stenosis in one or more arteries) and the rest 234 were the controls (maximum stenosis < 10% in any artery) according to the world health organization (who) diagnostic criteria. The multiple regression analysis showed that AIP was independently associated with CHD in men (odds ratio (OR) = 4.44, 95%CI 1.62-12.21, P = 0.004) after adjusting for age, body mass index (BMI), fasting blood glucose(FBG), homocysteine (Hcy), and smoking, but not in women (OR = 0.47, 95%CI 0.11-2.08, P = 0.318). Subgroup analysis showed that the significant difference in AIP between the CHD and the controls only exists in patients with multi-vessel lesions but not in those with single-vessel lesion. Further large-scale studies with balanced sex ratio and vessel lesion numbers should verify the present findings.
