Abstract
Background: Pulmonary hypertension (PH) is a hemodynamic and pathophysiological disease defined by a mean pulmonary artery pressure of ≥20 mm Hg. Pulmonary hypertension severity and prognosis play an essential role in the management of these patients. The aim of this study was to evaluate the prognostic value of platelet to lymphocyte ratio (PLR) and neutrophil to lymphocyte ratio (NLR) in patients with PH referred to Masih Daneshvari Hospital, Tehran, Iran.
Materials and Methods: A total of 61 patients with PH referred to Masih Daneshvari Hospital in Tehran were enrolled. Patients’ information such as age, sex, type of PH, echocardiographic data, and blood cell count, including platelet, lymphocyte, and neutrophil count, hemoglobin, and RDW, were collected in each follow-up.
Results: Out of 61 patients with PH, 27 (44.3%) were male, and 34 (55.7%) were female. The mean age of the patients was 43.19 ± 2.25 years. Our results showed that during hospitalization, PLR decreased from 13.2 to 9.7, and NLR also decreased from 4.49 to 3.08. Neither PLR nor NLR was associated with gender. However, both PLR and NLR showed a significant difference between deceased vs. discharged patients and were significantly lower in the patients who died.
Conclusion: Both PLR and NLR decreased during hospitalization in patients with PH, and this decrease was greater in the patients who died, suggesting these indicators as potential prognostic markers for the disease.
