background:The main healthcare funding systems in Brazil, the public and the private healthcare systems (PuHS and PrHS, respectively), have peculiar characteristics and cover almost all patients referred for percutaneous coronary intervention (PCI). Our objective was to identify population differences and PCI hospital outcomes in patients using both systems. Methods: From August 2006 to November 2010, 4,957 consecutive patients were submitted to PCI, 2,802 (56.5%) were from the PuHS and 2,155 from the PrHS. results: Patients from the PuHS were younger, had less education, greater incidence of smoking, prior myocardial infarction (MI), single-vessel disease, left ventricular dysfunction, and received more direct stenting. In the PrHS group, there was more diabetes, dyslipidemia, prior coronary bypass graft surgery (CABG) and PCI, prior stroke, chronic renal failure, ST-segment elevation and non-ST segment elevation acute coronary syndromes, restenotic lesions, long lesions, primary PCIs, use of glycoprotein IIb/IIIa inhibitors and drug-eluting stents. PCI success (96% vs. 96,1%; P = 0.87), MI (1.7% vs. 1.8%; P = 0.72), CABG (0.1% vs. 0.2%; P = 0.85), stroke (0.1% vs. 0.1%; P > 0.99) and death (1% vs. 1.2%; P = 0.48) were not different between groups. Conclusions: Patients from the PrHS had greater clinical and angiographic complexity than those from the PuHS. However, these differences did not affect the success of the procedure

background: Diabetics, especially insulin-treated diabetics, have more extensive coronary atherosclerosis and impaired vascular remodeling. Our objective was to evaluate in-hospital results of contemporaneous percutaneous coronary intervention (PCI) in a consecutive series of diabetics treated with (ITD) or without (NITD) insulin. Methods: Retrospective analysis of a multicenter registry with 1,896 diabetics, of which 397 (20.9%) were from the ITD group and 1,499 from the NITD group. Major adverse cardiac and cerebrovascular events (MACCE) were compared between groups. results: The ITD group showed a higher rate of women and of patients with chronic renal failure, but showed less complex angiographic characteristics when compared to the NITD group, with fewer B2/C lesions, thrombus-containing lesions, occlusions and TIMI 0/1 flow prior to PCI. We treated 1.4 ± 0.7 vessels/patient with 1.3 ± 0.7 stents/patient in each group and the diameter and length of stents were not different between groups. Clinical in-hospital outcomes showed no differences regarding the occurrence of MACCE (3.

Background: There are few available reports in the literature assessing in-hospital outcomes of diabetic patients currently undergoing percutaneous coronary intervention (PCI). This article aimed to assess the acute post-PCI outcomes of a large series of diabetic and non-diabetic patients treated consecutively. Methods: From August 2006 to February 2012, 6,011 patients were submitted to PCI and included in the registry of the Hospital Bandeirantes. The techniques and devices for the procedure were chosen by the surgeons. Clinical outcomes were registered at the time of hospital discharge. Results: Diabetic patients were older and more frequently females, with a higher prevalence of comorbidities and risk factors for coronary artery disease, except for smoking. However, most of the characteristics related to lesion complexity did not differ between groups. In diabetics, the number of treated vessels (1.6 ± 0.8 vs. 1.4 ± 0.7; P < 0.01) was higher, and the use of smaller stents (2.9 ± 0.5 mm vs. 3 ± 0.5 mm; P < 0.01) was more frequent. A procedural success rate of 95.5% was achieved in both groups. In-hospital outcomes did not differ in the incidence of major adverse cardiac and cerebrovascular events (3.

Background: The benefits of using thrombus aspiration catheters during primary percutaneous coronary intervention (PCI) to obtain better coronary flow and myocardial perfusion and to reduce late mortality are established in the literature. However, in clinical practice, this approach does not appear to be used for all patients. This study attempted to determine which clinical and angiographic variables have led to the use of these devices in primary PCI at this institution. Methods: From August of 2006 to November of 2010, 558 consecutive patients underwent primary PCI. Thrombus aspiration catheters were used in 79 patients (group 1), who were then compared to 479 patients in whom these devices were not used (group 2). Results: Group 1 showed a prevalence of males, smokers, large acute myocardial infarctions (AMI), and thrombotic lesions. The use of glycoprotein IIb/IIIa inhibitors, direct stenting, larger diameter stents, and the presence of transient coronary flow disturbances were also more frequent in group 1. The procedural success rate was high (93.7% vs. 92.3%; P = 0.4), and it was similar between groups. At hospital discharge, the incidence of major adverse cardiac and cerebrovascular events (6.3% vs. 6.5%; P = 0.6), death (5.1% vs. 3.8%; P = 0.58), stroke (1.3% vs. 0.4%; P = 0.09), and reinfarction (0% vs. 2.3%; P = 0.17) were not different between the groups. Conclusions: Thrombus aspiration catheters have been used in 15% of primary PCIs, usually in AMIs with greater extension and thrombotic burden. Despite the more severe clinical and angiographic profile of these patients, the success rate is high and similar to that of low-risk patients.

Background: Technological developments have enabled the expansion of percutaneous coronary intervention (PCI) indications for more challenging clinical and angiographic scenarios. Our objective was to evaluate the results of PCI in two different periods in the past 6 years. Methods: This was a multicenter registry including 6,288 consecutive patients treated by PCI, who were divided according to different treatment periods: 2006 to 2008 (P1; n = 1,779) and 2009 to 2012 (P2; n = 4,509). We intended to compare the rates of in-hospital major adverse cardiac and cerebrovascular events (MACCE) and identify their predictors. Results: P2 patients were younger and had a higher prevalence of smoking and diabetes. These patients had a greater rate of multivessel, thrombotic and bifurcation lesions. The number of diseased vessels per patient was higher in the P2 Group, as well as the number of stents per patient, and the use of drug-eluting stents. MACCE was more frequent in P2 patients (2.5% vs. 3.5%; P = 0.04), due to periprocedural myocardial infarction (1.7% vs. 2.6%; P = 0.05), and there were no differences in terms of death (1.0% vs. 1.0%; P = 0.87), stroke (0.2% vs. 0.1%; P = 0.47) or emergency coronary artery bypass grafting (0.1% vs. 0; P = 0.68).
