Neutrophil to Lymphocyte Ratio is Associated with Mid Term BPV in Hypertensive COVID-19 Patients a) Faculty of Medicine, Sebelas Maret University, Indonesia Abstract Neutrophil-to-lymphocyte (NLR) is an inexpensive and feasible inflammatory marker. Inflammation has a key role in pathogenesis and progression of COVID-19 with hypertension. Blood pressure control in hypertension is influenced by blood pressure variability. A total of 192 COVID-19 patients with hypertension who were administered to Sebelas Maret University Hospital in June 2020 to February 2022 were included in this observational analytical study with a cross-sectional approach. Data were analyzed using Spearman or Pearson correlation analysis. Comparative analysis of independent T-test or Mann Whitney were used on numerical variables and Chi-Square test on categorical variables. There is a positive (unidirectional) and significant correlation (r = 0,223, p= 0,002) between the NLR dan blood pressure variability in COVID-19 patients with hypertension at Sebelas Maret University Hospital. There was a significant difference in the variables of admission oxygen saturation <93% (p<0.001) and mortality (p<0.001) which were found higher in patients with high NLR levels (>5.8) than normal NLR levels (<5.8). This study showed that admission NLR is weakly and positively correlated with blood pressure variability in COVID-19 patients with hypertension at Sebelas Maret University Hospital. An increase of admission NLR above the upper normal limit, can elevate the blood pressure variability, therefore it needs to be considered.
