Introduction and Objectives: Ischemic cardiopathy constitutes the leading cause of death worldwide. Our aim was to evaluate the prognostic capacity of the leukoglycemic index as well as to create a predictive model of in-hospital complications in patients with ST elevation myocardial infarction. Materials and Methods: This was a multicentral and cohort study, which included patients inserted in the Cuban Registry of acute myocardial infarction. The study investigated 900 patients with a validation population represented by 233 external subjects. In order to define the performance of the leukoglycemic index were evaluated the discrimination with the statistical C and the calibration by Hosmer – Lemeshow test. A model of logistic binary regression was employed in order to define the predictive factors. Results: Optimal cut point of the leukoglycemic index to predict in-hospital complications was 1188 (sensibility 60%; specificity 61.6%; area under the curve 0.623; p < 0.001). In-hospital complications were significantly higher in the group with the leukoglycemic index ≥ 1188; a higher value was significantly associated with a higher risk to develop an in-hospital complication [RR (IC 95%) = 2.4 (1.804–3.080); p<0.001]. The predictive model proposed is composed by the following factors: age ≥ 66 years, leukoglycemic index ≥ 1188, Killip-Kimball classification ≥ II and medical history of hypertension. This scale had a good discrimination in both, the training and the validation population. Conclusions: The leukoglycemic index possesses a low performance when used to assess the risks for in hospital complications in patients with ST elevation myocardial infarction. The new predictive model has a good performance, which can be applied to estimate risk of in-hospital complications. This model would be able to contribute to the health systems of developing countries without additional cost; it enables prediction of the patients having a higher risk of complications and a negative outcome during the hospitable admission.
Objective To assess performance measures of attention of STEMI in Coronary Intensive Care Unit in General Hospital Camilo Cienfuegos.Methods Admitted patients with STEMI, from February-April 2020, were compared with patients from similar period from 2015–2019, and patients from January 2019 to January 2020. Primary endpoint were performance measures according to the 2017 AHA / ACC Clinical Performance and Quality Measures for Adults with STEMI document, and secondary endpoint were all-cause in-hospital mortality and major acute coronary events.Results Only 35 patients were admitted from February-April 2020. When comparing with similar periods from recent years, in-hospital death (8.3 % vs. 20 %; p=0.03), major complications (38.7 % vs. 57.1 %; p=0.03), and cardiogenic shock (6.9 % vs. 17.4 %; p=0.04) were significantly higher. When comparing with 2019 and January 2020, in-hospital death (9.6 %; p=0.04), and major complications (35.8 % p=0.03) were significantly higher in February-April 2020; however, there was no difference in prevalence of cardiogenic shock (8 %; p=0.12).Conclusion COVID-19 pandemic had decreased prevalence of STEMI, as well as some performance measures of attention in this center.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
