ObjectiveTo apply and to compare the Society of Thoracic Surgery score (STS), EuroSCORE (Eurosc1), EuroSCORE II (Eurosc2) and InsCor (IS) for predicting mortality in patients undergoing to coronary artery bypass graft and/or valve surgery at the Santa Casa Marilia.Methods The present study is a cohort. It is a prospective, observational, analytical and unicentric. We analyzed 562 consecutive patients coronary artery bypass graft and/or valve surgery, between April 2011 and June 2013 at the Santa Casa Marilia. Mortality was calculated for each patient through the scores STS, Eurosc1, Eurosc2 and IS. The calibration was calculated using the Hosmer Lemeshow test and discrimination by ROC curve.ResultsThe hospital mortality was 4,6%. The calibration is generally adequate group P =0.345, P =0.765, P =0.272 and P =0.062 for STS, Eurosc1, Eurosc2, and IS respectively. The discriminatory power of STS score 0.649 (95% CI 0.529 to 0.770, P =0.012), Eurosc1 0.706 (95% CI 0.589 to 0.823, P ≤0.001), Eurosc2 was 0.704 (95% CI 0.590-0.818 P =0.001) and InsCor 0.739 (95% CI 0.638 to 0.839, P ≤0.001).ConclusionWe can say that overall, the InsCor was the best model, mainly in the discrimination of the sample. The InsCor showed good accuracy, in addition to being effective and easy to apply, especially by using a smaller number of variables compared to the other models.

Background:The mechanisms and predictors of failure of the transradial approach in centers dedicated to this technique are not well characterized and were the main objective of this analysis. Methods: 6,808 consecutive patients undergoing transradial coronary procedures by operators with utilization rate greater than 90% were included. Simple and multiple logistic regression models were used to identify the predictors of failed transradial approach. Results: Transradial failure rate was 1.7%. Vascular complications were observed in 5% of the sample, with a prevalence of asymptomatic arterial occlusion and subcutaneous hematomas. Predictors of failure were female gender (OR = 1.87; 95% CI: 1.29-2.71; p = 0.01), age > 70 years (OR = 1.78; 95% CI: 1.06-2.98; p = 0.03) and presence of chronic peripheral arterial disease (OR = 5.71; 95% CI: 2.40-13.54; p < 0.01). Conclusions: In a high-volume radial center, the failure rate was < 2% and variables associated with failure of the technique were female gender, advanced age and peripheral arterial disease.
