CAMI-NSTEMI Score　― China Acute Myocardial Infarction Registry-Derived Novel Tool to Predict In-Hospital Death in Non-ST Segment Elevation Myocardial Infarction Patients ―

Abstract

The CAMI-NSTEMI score is able to accurately predict the risk of in-hospital mortality in NSTEMI patients.

Comparison of the CAMI-NSTEMI and GRACE Risk Model for Predicting In-Hospital Mortality in Chinese Non-ST-Segment Elevation Myocardial Infarction Patients

“…To address the limitations mentioned above, the CRM was developed to predict in-hospital mortality, particularly for Chinese NSTEMI patients, and its diagnostic performance was superior to that of the GRM in two internal validation studies using data from CAMI registry [ 8 , 9 ]. Our effort further extended this conclusion in an external validation cohort by indicating a larger AUC, positive NRI, and less disagreement between the observed and predicted mortality for the CRM.…”

“…According to the GRM and guideline recommendations, we classified patients into 3 risk groups: the low-, medium-, and high-risk group [ 1 ]. The CRM identified 11 independent predictors of in-hospital mortality: age, BMI, SBP, Killip class, cardiac arrest, ST-segment depression, Cr, WBC smoking status, previous MI, and previous percutaneous coronary intervention, and all patients were classified into 3 risk groups based on the CRM [ 8 ].…”

“…To diminish the impact of this paradox, the current guidelines consider the risk assessment by the Global Registry of Acute Coronary Events (GRACE) risk model as a fundamental component to select the most appropriate therapeutic strategy for NSTEMI patients [ 1 – 3 ]. However, several observations have suggested that the performance of the GRACE risk model (GRM) was unsatisfactory among Chinese NSTEMI patients [ 8 , 9 ]. Recently, a novel risk model has been developed for the risk evaluation of NSTEMI patients [ 8 ] based on multicenter data from the China Acute Myocardial Infarction (CAMI) registry [ 10 ].…”

Simple risk score based on the China Acute Myocardial Infarction registry for predicting in-hospital mortality among patients with non-ST-segment elevation myocardial infarction: results of a prospective observational cohort study

“…Additionally, to our knowledge, no risk scores have been focused on patients with NSTEMI. To bridge the knowledge gap, our team previously developed and validated a novel risk score for predicting the in-hospital mortality risk among patients with NSTEMI based on the China Acute Myocardial Infarction (CAMI) registry (ie, CAMI-NSTEMI score) 7…”
