RESUMEN
OBJECTIVE: To assess the impact of diabetes on 2-year mortality in current PCI practice. BACKGROUND: In patients with coronary artery disease undergoing revascularization, diabetes mellitus is associated with higher mortality. METHODS: A retrospective analysis was done of all patients undergoing PCI at our tertiary center between January 2000 and December 2004. There were 6,160 PCI procedures performed in 5,759 patients who received at least one stent. Of these patients, 801 (13.9%) were diabetic and 4,958 (86.1%) were nondiabetic. The primary outcome measure of the study was all-cause mortality. All patients were followed up for a period of 2 years. Multivariate logistic regression analysis was used to test for a potential independent association between diabetic status and follow-up mortality. RESULTS: Before adjustment, a trend toward higher mortality was observed in diabetic patients compared to non-diabetics at 1 year (3.2% vs 2.4%) and 2 years (5.1% vs 3.8%), P = 0.12. Independent predictors for mortality were increasing age, renal dysfunction, peripheral vascular disease, NYHA class >2, urgent PCI, treating left main stem lesions, vessel diameter < or = 2.5 mm, and 3-vessel disease. The use of drug-eluting stent was associated with a reduction in mortality. Diabetes was found to have no independent impact on mortality following PCI (odds ratio = 1.08; 95% confidence intervals = 0.73-1.60; P = 0.71). CONCLUSION: The presence of diabetes was not an independent predictor of mortality following PCI. A diabetic patient that does not require insulin treatment and has no evidence of macro- or microvascular diabetic disease could enjoy a PCI outcome similar to nondiabetic subjects.

UNLABELLED: Percutaneous closure of atrial septal defect (ASD) and patent foramen ovale (PFO) has become increasingly utilized. The indications and results of percutaneous closure are diverse. AIM: To assess the indications, results, and complications of percutaneous closure of ASD and PFO in our tertiary center. METHOD: Case note review and retrospective analysis of all consecutive patients undergoing percutaneous closure over a 3-year period from January 2003 to October 2005 with a mean follow-up of 19 months (4-36). RESULTS: There were 185 consecutive patients. The mean age was 44.9 years (SD 12.9) and 53% (n = 98) were males. There was 59% (n = 109) PFO and 41% (n = 76) ASD. The predominant indication for PFO closure was cerebrovascular accident (CVA) (42.2%, n = 46)- and for ASD, dilated right ventricle (68.4%, n = 52). Of all procedures, 94.6% (n = 175) were first time and 5.4% (n = 10) were redo for residual shunt. Overall, the success rate was 96.8% (n = 179) with two patients referred for surgical closure due to the large size of ASD and unsuitability for percutaneous closure, two procedures abandoned due to pericardial effusion, and two abandoned because the PFO was too small to cross. The Amplatzer device was used in 92.7% (n = 166) and the Starflex in 7.3% (n = 13). Minor complications were recorded in 10 patients (5.4%), of which 4 (2.2%) had minor venous access bleeding, 1 patient (0.5%) had retroperitoneal hematoma, and 2 patients (1.1%) had transient atrial fibrillation. One patient (0.5%) had transient inferior ST elevation during the procedure, one patient (0.5%) reported chest pain postprocedure, and one patient (0.5%) developed septicemia 3 weeks postprocedure. Major complications were recorded in three patients (1.5%), one patient (0.5%) with retroperitoneal hematoma requiring blood transfusion and two patients (1%) with pericardial effusion following transseptal puncture, requiring aspiration. No death, stroke, or device embolization was recorded. CONCLUSION: Our experience with percutaneous closure in adults demonstrates excellent results and safety with few complications. Percutaneous device closure will replace surgical closure for many ASDs and PFOs.

OBJECTIVE: It has been suggested that macrovascular disease is more common in patients with scleroderma (SSc). We investigated the prevalence of coronary artery disease (CAD) in SSc using coronary angiography. METHODS: Coronary angiography was performed in 172 patients with SSc and suspected CAD to examine the prevalence of significant CAD. The prevalence of CAD was estimated in the whole group and also according to age, gender and type of symptoms (typical angina, atypical angina and non-anginal pain or breathlessness). Standardized prevalence ratios (SPRs) were calculated in each symptomatic group in order to compare CAD rates amongst our observed population with those predicted using the Diamond and Forrester (D & F) probability analysis. This analysis provides an estimate of the probability of CAD based on gender, age and symptoms in subjects aged between 30-69 yrs. RESULTS: The observed prevalence of CAD in the whole population was 22% (38/172); 17% (6/36) in males and 23% (32/136) in females. A total of 41 patients were excluded because they were outside the age range for D & F analysis. Compared with the reference population, the SPRs for CAD in the three SSc groups were: 47% (95% CI 21.7-89.9) in the typical angina group (22 patients), 50% (95% CI 13.6-128) in the atypical angina group (22 patients) and 93% (95% CI 49.4-158.8) in the non-anginal pain or breathlessness group (87 patients). CONCLUSION: The prevalence of CAD in patients with SSc is similar and not greater to that expected in individuals without SSc.
