Abstract

Background

Acute heart failure is a heterogenous syndrome defined by a number of factors, such as its physiopathology, clinical picture, time of onset, and relation to acute coronary syndrome. Acute cardiogenic pulmonary edema (ACPE) constitutes approximately 10–20% of acute heart failure syndromes, and it is the most dramatic symptom of left heart failure. Platelet to lymphocyte ratio (PLR) is a relatively novel inflammatory marker that can be utilized for prognosis in various disease processes.

Objective

In this study, we investigated the value of the PLR for the prediction of mortality in patients with ACPE.

Methods

A total of 115 patients hospitalized with a diagnosis of ACPE were included in this study. The patients were divided into tertile groups according to their PLR values: high (PLR > 194.97), medium (98.3–194.97), and low tertile (PLR < 98.3).

Results

We compared the PLR groups for in-hospital mortality and total mortality after discharge. Multivariate Cox regression analysis showed that PLR was independently associated with total mortality (hazard ratio 5.657; 95% confidence interval 2.467–12.969; p < 0.001). Survival analysis using the Kaplan–Meier curve showed that the high-PLR group had a significantly higher mortality rate than the other groups.

Conclusions

We showed an association between high PLR and mortality in patients with ACPE. PLR, together with other inflammatory markers and clinical findings, may be used as an adjunctive parameter for the stratification of mortality risk, hospitalization, or discharge criteria scoring.
