RESUMO
Abstract Background The SHARPEN score was developed to predict in-hospital mortality in patients hospitalized for infective endocarditis (IE), undergoing or not undergoing cardiac surgery. A comparison with other available scores has not yet been carried out. Objective To evaluate the performance of the SHARPEN score in predicting in-hospital mortality in patients hospitalized for IE undergoing cardiac surgery and compare it with that of both nonspecific and IE-specific surgical scores. Methods Retrospective cohort study including all admissions of patients ≥18 years who underwent cardiac surgery due to active IE (modified Duke criteria) at a tertiary care university hospital between 2007 and 2016. The SHARPEN score was compared to the EuroSCORE, EuroSCORE II, STS-IE, PALSUSE, AEPEI, EndoSCORE and RISK-E scores. Differences P<0.05 were considered statistically significant. Results A total of 105 hospitalizations of 101 patients (mean age 57.4±14.6 years; 75.2% male) were included. The median SHARPEN score was 11 (9-13) points. The observed in-hospital mortality was 29.5%. There was no statistically significant difference in observed vs. estimated mortality (P = 0.147), with an area under the ROC curve of 0.66 (P = 0.008). In comparison with the other scores, no difference was observed in discriminative ability. The statistics of the SHARPEN score at a cutoff >10 points — positive predictive value (PPV): 38.1%, 95%CI:30.4-46.6; negative predictive value (NPV): 80.0%, 95%CI:69.8-87.4; and accuracy: 58.1%, 95%CI:48.1-67.6 — showed overlapping 95%CIs, indicating no significant difference between scores. Conclusions The SHARPEN score did not present parameters with a significant difference in relation to the other scores analyzed; despite the easy obtainment of its few variables, it has limited applicability in clinical practice, like other existing scores.
RESUMO
Background: Although new studies and guidelines can be considered useful tools, it does not necessarily mean they are put into clinical practice. Objective: The aim of the current analysis was to assess the changes in primary percutaneous coronary intervention (PCI) and mortality in a tertiary university hospital in southern Brazil during a six-year period .Methods: We have included consecutive patients with ST-elevation myocardial infarction (STEMI) who underwent primary PCI between March 2011 and February 2017. Previous clinical history, characteristics of the procedure, and reperfusion strategies were collected. In-hospital, short and long-term mortalities were also evaluated. The significance level adopted for all tests was 5%. Results: There was an increase in the use of radial access in patients from 20.0% in 2011 to 62.7% in 2016 (ptrend < 0.0001). Moreover, thrombus aspiration decreased significantly from 66.7% in 2011 to less than 3.0% in 2016 (ptrend < 0.0001). In-hospital, short and long-term mortalities remained reasonably stable from 2011 to 2016 (ptrend > 0.05). However, a lower in-hospital mortality was observed in patients treated through radial access (p < 0.001). Cardiogenic shock occurred in 11.1%, without statistical differences in the period (ptrend = 0.39), while long-term mortality rate decreased from 80.0% in 2011 to 27.3% in 2016 in this patient group (ptrend = 0.29). Conclusions: During a 6-year follow-up period, primary PCI characteristics underwent important modifications. Radial access became widely used, with a decrease in mortality with the use of this route, while aspiration thrombectomy became a rare procedure. The incidence of cardiogenic shock remained stable, but has shown a reduction in its mortality
