Background: Early risk stratification plays a crucial role in the treatment of non-ST-elevation myocardial infarction (NSTEMI). Selvester score is an electrocardiography (ECG)-based method for estimating infarcted myocardial mass, however it has not been studied in NSTEMI before. In this study, we aimed to investigate the relationship between Selvester score and cardiovascular outcomes in a 1-year follow-up period in NSTEMI patients.
Methods: One hundred and forty-three consecutive patients with NSTEMI were analyzed. TIMI and GRACE risk scores were calculated accordingly. Selvester score was calculated on surface ECG as reported in prior studies. Syntax score was calculated using an online calculator. The study population was divided into two groups based on a cut-off value from receiver operating characteristic curve analysis for the discriminative ability of Selvester score for mortality: low score (≤ 4), and high score (> 4) groups.
Results: Age was higher, left ventricle ejection fraction and high-density lipoprotein-cholesterol levels were significantly lower, and TIMI, GRACE and SYNTAX scores were significantly higher in the high Selvester score group. In multivariate Cox regression analysis, ejection fraction [hazard ratio (HR): 0.926, 95% confidence interval (CI): 0.883-0.971, p = 0.002] and Selvester score > 4 (HR: 3.335, 95% CI: 1.306-8.503, p = 0.012) were found to be independent predictors of adverse events after 1 year of follow-up.
Conclusions: Selvester score is a fast and feasible method that has prognostic value for mortality and other major adverse outcomes in low and intermediate risk NSTEMI patients treated with urgent percutaneous coronary intervention for 12 months.

Prediction of major adverse cardiovascular events following acute myocardial infarction using electrocardiogram DETERMINE score.

Background: Acute myocardial infarction (AMI) remains a major cause of mortality and morbidity globally, with a high incidence of major adverse cardiovascular events (MACE) post-primary percutaneous coronary intervention (PPCI). The DETERMINE score, derived from electrocardiographic (ECG) markers, has shown promise as a predictor of adverse outcomes, but its clinical utility requires further validation.
Objective: To evaluate the predictive value of the DETERMINE score for MACE and provide early clinical warnings for high-risk patients.

Introduction: Myocardial Infarct Size (IS) determined soon after ST-segment elevation myocardial infarction (STEMI) has prognostic significance, and can be assessed by cardiac biomarker levels, electrocardiographic (ECG) parameters, and imaging modalities (including echocardiography and cardiac magnetic resonance imaging [CMRI]).
Objectives And Methods: We evaluated methods of IS assessment, 12-lead ECG Selvester QRS scores and high-sensitivity Troponin T (hsTnT) levels measured ≥48hr (plateau phase of hsTnT elevation), compared to paired CMRIs and echocardiograms, in a prospective cohort of patients with STEMI undergoing percutaneous coronary intervention (PCI) during the index hospitalisation. Associations were determined between IS, as assessed by these methods, and 24-month major adverse cardiac events (MACE), a hierarchical composite of: death, stroke and hospitalization for heart failure.

Aims: The Selvester scoring system has been derived from ECG parameters for estimating infarct size. However, there is still a lack of evidence for Selvester score as an alternative to cardiac magnetic resonance (CMR) myocardial injury makers for risk stratification and prediction of left ventricular function (LVF) recovery among patients with ST-segment elevation myocardial infarction (STEMI).
Methods And Results: This multicentre observational study enrolled 328 STEMI patients (88.

Background: The Selvester QRS (S-QRS) score on a 12-lead electrocardiogram (ECG) is associated with both the amount of myocardial scar and poor prognosis in myocardial infarction patients. However, its prognostic value in heart failure (HF) with preserved ejection fraction (HFpEF) is unknown.
Objective: This study aims to investigate the predictive value of the S-QRS score for mortality in HFpEF.
