BACKGROUND: Nowadays, heart failure (HF) is a significant health problem due to steady increase in diagnosis, unpredictable acute decompensations and high mortality rate. Early risk stratifications of clinical deterioration are essential in preventing life-threatening events and ensuring proper patients management. Increased neutrophil to lymphocytes ratio (NTLR) above 6 is associated with the risk of re-hospitalizations and increased mortality.
OBJECTIVES: To compare NLTR and clinical, laboratory and hemodynamic results obtained from patients re-hospitalized within six-month intervals due to HF decompensation.
MATERIAL AND METHODS: We evaluated 41 patients (n = 36 males (87%) and n = 5 females (13%), mean age 50 ±10 years) admitted to our hospital at least twice within six-month interval due to decompensation of chronic heart failure (CHF) between 2017 and 2019. All patients were divided into 2 groups depending on the NTLR values.
RESULTS: There was no death in presented group during the observational time. We observed a significant difference in cardiac index (CI) - 2.4 ±0.5 compared to 2.6 ±0.6 L/m2/min - between the 1st and 2nd admission (p = 0.0356). The right ventricle systolic pressure (RVSP) results related to NLTR level revealed significant difference (43 ±14 mm Hg compared to 59 ±21 mm Hg, p = 0.0438). We observed a significant increase of pulmonary vascular resistance (PVR) values (175 ±106 compared to 438 ±300 dyn*s*cm-5, p = 0.0386) in patients with NLTR above 6.
CONCLUSIONS: Neutrophil to lymphocyte ratio may be an easy and suitable tool for monitoring of the HF progression. According to our study, the ratio correlates with PVR and RVSP increase.
