Abstract
Background: In patients with documented right coronary artery (RCA) lesions, right ventricular function could be affected. In addition, the presence of diabetes mellitus is found to be a risk factor for cardiomyopathy.
objective: The aim of the study is to assess the effect of type II DM on RV function in patients with chronic stable angina who have significant RCA lesion, using TAPSE and TDI by echocardiography
Patients and Methods: One hundred patients who underwent elective coronary angiography for suspected coronary artery disease and were found to have significant RCA lesion were divided into two groups according to presence of Type II DM. Echocardiography was done for all patients and RV function assessment by TAPSE and TDI was done.
Results: In our study 100 patients were included ;73 of patients were males and 27 were females with mean age of 56.70 ± 8.51 years. almost one fourth of the candidates were smokers, 23% were ex-smokers and about half of the candidates were non-smokers (51%).About half of the patients were known hypertensive (48%) while the rest were not. As regarding LVEF it ranged between 35-73 % with a Mean ± SD of 54.10 ± 8.94, TAPSE ranged between 17-30 mm with a mean ± SD of 22.81 ± 3.08 and S ’ was ranged between 9-19cm/s with a mean ± SD of 13.50 ± 2.24. Comparison between both groups showed that control group (group I) had a mean age of (57.34 ± 8.74) and 86% were males . All Diabetic patients (group II) had a mean age of (56.06 ± 8.30) years, (60%) were males. There was no significant difference between the two groups with respect to age and gender. As regarding smoking status in group II (20%) were smokers and for group I (32%) . As regarding hypertension, in group II (72%) were hypertensive and for the group I (32%) were hypertensive which was significantly different in both groups.The presence of associated significant LAD lesions was found in 52% of group II and only 32% in group I, which was significantly differenct between 2 groups. (p=0.043).As regarding Echocardiographic data, there was no significant difference in both groups regarding TAPSE (P value .629) and S’(P value .247).
Conclusions: The results of this study shows that TAPSE and S’ showed normal values in patients with chronic stable angina and there was no additional effect for type II D.M.
