Background: To evaluate the prognostic accuracy of the Get With The Guidelines-Heart Failure (GWTG-HF) score, Shock Index (SI), Modified Shock Index (MSI), and Age Shock Index (Age-SI) alone and with lactate in patients with acute symptomatic heart failure (HF).

Methods: A retrospective cohort study was conducted in the emergency department of a tertiary hospital between January 1, 2019, and December 31, 2019. Patients aged >18 years and diagnosed with acute symptomatic HF were consecutively included in the study. Patients referred from another center and missing medical records were excluded. Arrival type, vital parameters, demographic characteristics, comorbid diseases, consciousness status, laboratory results, and outcomes of the patients were recorded. The primary endpoint of the study was in-hospital mortality.

Results: A total of 368 patients were included in the final analysis. The in-hospital mortality rate of the patients was 7.6%. The GWTG-HF score outperformed other scores in predicting in-hospital, 24-hour, and 30-day mortality (area under the curve (AUC) = 0.807, 0.844, and 0.765, P <.001, respectively). The overall performance of the GWTG-HF score with lactate (GWTG-HF+L) was better in predicting in-hospital, 24-hour, and 30-day mortality than the original GWTG-HF score (AUC = 0.872, 0.936, and 0.801, P <.001, respectively). Adding lactate values to the SI, MSI, and Age-SI improved their overall performance for all 3 outcomes.

Conclusion: Both the GWTG-HF and GWTG-HF+L scores have acceptable discriminatory power in patients with acute symptomatic HF. The GWTG-HF score, SI, MSI, and Age-SI can be used together with lactate to predict mortality in patients with acute HF.
