Key result
The baseline Selvester QRS score was an independent predictor of 3-month re-hospitalization in patients with ischemic heart failure (HR 1.12; 95% CI 0.95-1.34; P=0.04).
Why the study?
Although the Selvester QRS score on surface ECG has shown prognostic value for cardiac events related to myocardial scarring, its utility for predicting re-hospitalization in ischemic HF required evaluation.

Hazard Ratio: 1.12 (95% CI 0.95–1.34)
p-value: p=0.04
The Selvester QRS score calculated from a baseline admission ECG can independently predict the risk of short-term re-hospitalization in patients with ischemic heart failure.
Should not yet alter practice for re-hospitalization risk assessment in ischemic HF; leaves open prospective validation of Selvester QRS score.
Aim: The Selvester QRS score (SSc) on surface electrocardiogram (ECG) has prognostic value in various cardiac events related to myocardial scarring. Furthermore, the SSc system has been validated by post-mortem studies. In this cohort, we assessed the utility of the SSc system for prediction of re-hospitalization in patients with ischemic heart failure (HF). Methods: In this retrospective cohort study, the data of fifty-four consecutive patients with ischemic HF were analyzed. ECGs were collected at first day of admission and SScs were calculated. The primary endpoint was re-hospitalization within the first 3 months. Results: At baseline, the mean age was 62.1 years, LVEF was 29(6) %, NT-proBNP level was 2830 pg/mL. Twenty-one re-hospitalizations were observed due to HF. Patients who were re-hospitalized had significantly higher SScs than those who were not (5.6 vs.3.3 P= 0.01). Cox regression analysis demonstrated that the SSc was an independent predictor of re-hospitalization rate (HR, 1.12; 95% CI, 0.95–1.34; P=0.04). Roc curve analysis showed that SSc was predictive for rehospitalization with a cut-off value 4.3, with a sensitivity of 65% and a specificity of 49% (AUC 0.618, P=0.02). Our analysis indicated a positive correlation between SSc with NT-proBNP and a negative correlation between SSc and LVEF (respectively r=0.33, P=0.03 and r =-0.67, P=0.04). Conclusion: Our results suggest that baseline SSc can be used as a predictor of re-hospitalization due to ischemic HF.

Karakuş et al. (2020) conducted a cohort in ischemic heart failure (n=54). Selvester QRS score (SSc) was evaluated on re-hospitalization within the first 3 months (HR 1.12, 95% CI 0.95-1.34, p=0.04). The baseline Selvester QRS score was an independent predictor of 3-month re-hospitalization in patients with ischemic heart failure (HR 1.12; 95% CI 0.95-1.34; P=0.04).
