title: Angiographic severity and morphological spectrum of coronary artery disease in non insulin dependent diabetes mellitus.
abstract: Coronary angiographic profile of 75 patients (63 males and 12 females) with noninsulin dependent diabetes mellitus (NIDDM) and CAD was compared with 75 nondiabetic patients (63 males and 12 females) with CAD. No difference was present between the mean age (56.2 +/- 7.4 vs 56.1 +/- 7.7 years; p = NS), presenting complaints (67 unstable angina and 8 stable angina with positive TMT in both the groups) and other coronary risk factors between the two groups. Severity and diffuseness of coronary artery involvement was assessed by a coronary artery score (CAS) using the segmental distribution method for coronary artery lesions. Diabetic patients with CAD had a higher CAS (18.7 +/- 10.3) as compared to the nondiabetic patients with CAD (12.7 +/- 9.6) (p < 0.01). Diabetic patients with CAD had a higher number of TVD [43 (57.3%) vs 31 (41.3%); p < 0.01] while the DVD and SVD was not significantly different. As compared to the nondiabetic group, diabetics had a higher total number of coronary artery lesions (300 vs 200; p < 0.001), a higher lesion per patient ratio (4.0 lesions/patient vs 2.6 lesions/patient; p < 0.001), a higher number of concentric lesions, [151 (50.3%) vs 90 (45%); p < 0.01] and a higher number of multiple irregularity lesions, [36 (21%) vs 27 (9%); p < 0.05]. The diffuse involvement of vessels was not significantly different between the two groups in LAD (12.1% vs 5.3%; p = NS), LCx (14.2% vs 5.8%; p = NS) and RCA (10.5% vs 5.0%; p = NS).(ABSTRACT TRUNCATED AT 250 WORDS)
