| description | Different ways have been used to stratify risk in acute coronary syndrome (ACS) patients. The aim of the study was to examine the usefulness of echocardiographic parameters as predictors of in-hospital outcome in patients with ACS after percutaneous coronary intervention (PCI). A data of 2030 patients with diagnosis of ACS hospitalized from December 2008 to December 2011 was used to develop a risk model based on echocardiographic parameters using the binary logistic regression. This model was independently evaluated in validation cohort prospectively (954 patients admitted during 2012). In-hospital mortality in derivation cohort was 7.73%, and 6.28% in validation cohort. Developed model has been designed with 4 independent echocardiographic predictors of in-hospital mortality: left ventricular ejection fraction (LVEF RR =0.892; 95%CI =0.854–0.932, P<0.0005), aortic leaflet separation diameter (AOvs RR =0.131; 95%CI =0.027–0.627, P=0.011), right ventricle diameter (RV RR =2.675; 95%CI =1.109–6.448, P=0.028) and right ventricle systolic pressure (RVSP RR =1.036; 95%CI =1.000–1.074, P=0.048). Model has good prognostic accuracy (AUROC =0.84) and it retains good (AUROC =0.78) when testing on the validation cohort. Risks for in-hospital mortality after PCI in ACS patients using echocardiographic measurements could be accurately predicted in contemporary practice. Incorporation of such developed model should facilitate research, clinical decisions, and optimizing treatment strategy in selected high risk ACS patients. |
