The Correlation Between TG Levels And The Extent Of The Coronary Artery Lesions Of Patients With Type 2 Diabetes

Objective:To observe the correlation between TG levels and the extent of the coronary artery lesions of patients with Type 2 Diabetes.Methods:508 Type 2 Diabetes patients underwent for coronary angiography were divided into three groups according to the TG levels:group 1(n=244,TG＜1.6mmol/L);group2(n=78,1.6≤TG≤2.2mmol/L);group3(n=185,TG＞2.2mmol/L).Results:(1) Multiple Regression-Correlation Analysis showed that TG levels were significantly correlated with following factors:TG(r=0.489,p＜0.001),BMI(r=0.119,p＜0.05),TC(r=0.765,p＜0.001) and HDL(r=-0.192,p＜0.001).After controlling other factors in the Multifactor Correlation Analysis,correlation between TG levels and coronary score was also exist(r=0.4681,p＜0.001).(2) The number of one-vessel CAD in group lwas significantly more than that in group 2 and 3(45.1%vs28.2%vs8.6%,P＜0.050).But three-vessel CAD in the group 3was significantly the most(50.8%vs23.1%vs11.5%,P＜0.05).(3) The number of coronary arteries that had at least ninety percent narrowing in group 3 was significantly more than in group 1 and 2(61.6%vs29.5%vs10.1%,P＜0.05).(4) Among all of the narrowing coronary arteries,the anterior descending coronary artery was the vessel most frequently involved,followed by RCA,LCX,LM.(5) The coronary score of group 3 was significantly higher than group 1 and 2(4.95±2.342 vs 9.03±3.542vs13.7±4.043,P1.2,P2.3＜0.05,P1.3＜0.001).Conclusions:(1) TG is a independent risk factor of CHD.(2)With the TG levels increasing,the total number of the narrowing coronary arteries will also increases,and the coronary artery lesions will be more and more serious.
