Abstract
Background
Coronary artery disease is one of the main causes of death in diabetes mellitus (DM). Egypt was listed among the world top 10 countries regarding the number of diabetic patients by the International Diabetes Federation (IDF).
Aim of work
Assessment of the extent of coronary atherosclerotic disease and lesion tissue characterization among diabetic compared to non-diabetic Egyptian patients.
Methodology
IVUS studies of 272 coronary lesions in 116 patients presented with unstable angina were examined. The patients were divided into two groups: diabetic group (50 patients with 117 lesions) and non-diabetic group (66 patients with 155 lesions).
Results
As compared to the non-diabetic group, the diabetic patients were more dyslipidemic (84% vs 39.4%, p = 0.001) with higher total cholesterol level (194.6 ± 35.3 vs 174.4 ± 28.5 mg/dl, p = 0.001) and higher LDL-C (145.3 ± 27.1 vs 123.2 ± 31.4, p = 0.001). Regarding lesions characteristics, the diabetic group had longer lesions (19.4 ± 7.4 vs 16.3 ± 7.9 mm, p = 0.002) with higher plaque burden (60.8 ± 15.3 vs 54.8 ± 14.0, p 0.002) and more area stenosis percentage (60.8 ± 15.6 vs 55.6 ± 14.1, p = 0.008). Structurally, the diabetic group lesions had more lipid content (19.8 ± 8.8 vs 16.8 ± 8.7, p = 0.008) and more necrotic core (17.6 ± 7.4 vs 14.7 ± 4.8, p = 0.008) but less calcification (6.9 ± 3.6 vs 11.8 ± 6.3, p = 0.001). The RI was negative in both groups, 0.95 ± 0.13 in the diabetic group vs 0.98 ± 0.19 in non-diabetic group (p = 0.5). Within the diabetic group lesions, the dyslipidaemic subgroup had more lipid content (23. ± 5.2 vs 14.6 ± 8.6, p = 0.01) but less fibrotic component (48.6 ± 4.7 vs 59.1 ± 13.6%, p = 0.01) and less calcification (10.9 ± 6.8% vs 14.07 ± 3.8%, p = 0.02) as compared to the nondyslipidaemic subgroup.
Conclusions
Diabetic patients with coronary atherosclerosis in Egypt have longer lesions with higher plaque burden and more percent area stenosis with negative remodeling index. The diabetic lesions had more lipid content and more necrotic core but less calcification.
期刊介绍：
The Egyptian Heart Journal is the official journal of the Egyptian Society of Cardiology. It is an international journal that publishes peer-reviewed articles on all aspects of cardiovascular disease, including original clinical studies and translational investigations. The journal publishes research, review articles, case reports and commentary articles, as well as editorials interpreting and commenting on the research presented. In addition, it provides a forum for the exchange of information on all aspects of cardiovascular medicine, including educational issues.
