Indo Heart Survey on latent abnormal glucose regulation in patients with coronary artery disease without diabetes across India.

BACKGROUND: The Euro Heart Survey on diabetes and heart has demonstrated high prevalence of latent glucose abnormalities in non-diabetic patients with coronary artery disease (CAD) in the European population. The aim of our survey was to assess the prevalence of latent abnormal glucose regulation in adult non-diabetic CAD patients in India. METHODS AND RESULTS: Seven centers distributed across India recruited 350 patients. The diagnosis of CAD was done by coronary angiography showing >50% stenosis in any major epicardial coronary artery or its branches. Oral glucose tolerance test (OGTT) and fasting glucose levels were used to characterize glucose metabolism. Venous plasma glucose was measured before (fasting) and 2 hours after ingestion of glucose. Impaired fasting glucose (IFG) was defined as OGTT (0 minute)>or=100 mg/dl but <126 mg/dl and OGTT (2 hours)<140 mg/dl. Impaired glucose tolerance (IGT) was defined as OGTT (0 minute)<126 mg/dl and OGTT (2 hours)>or=140 mg/dl but <200 mg/dl. Of the 350 patients studied, 176 (50.28%) had impaired glucose regulation (IFG-28 [8%]; IGT-148[42.28%]) and 75 (21.42%) had newly detected Diabetes. In all 251 (71.7%) patients with CAD had previously undetected abnormal glucose regulation. CONCLUSION: This survey demonstrates the presence of abnormal glucose regulation in almost three quarters of the non-diabetic Indian CAD patients. OGTT should be recommended as routine screening test for detecting latent glucose abnormalities in all CAD patients.

Taussig-Bing complex--a pathologic study of eight cases.

Taussig-Bing Complex, an uncommon anomaly, was found in 8 out of 110 hearts of double outlet right ventricle (7.2%). The mean age at death was 23.5 months with maximum survival upto 10 years. There was only one case of dextrocardia; viscero-atrial and atrio-ventricular concordance was seen in all. Subpulmonary ventricular septal defect (VSD) was restrictive in two cases, in one of whom it was due to spontaneous closing process. Additional VSD was found in 2 cases. The great vessels showed side by side relationship with bilateral conii in 7 cases. In the remaining case there was L malposition with absent subpulmonary conus. Subpulmonary stenosis was noted in 3 cases. Tubular hypoplasia of aorta was seen in 2 cases with subaortic obstruction in one. Mitral valve abnormalities were present in 5 cases of which stenotic lesions were seen in 3. Coronary artery abnormalities were noted in 3 cases.

Unruptured aneurysm of sinus of Valsalva: report of 2 cases.

2 cases of unruptured aneurysm of the sinus of Valsalva are presented. Both the patients had involvement of the right sinus of Valsalva. One of the patients had associated systemic lupus erythematosus (SLE). Such an association has not been described in the literature. Clinical, echocardiographic and the angiographic features have been discussed and literature reviewed.
