Exaggerated morning surge; systemic immune-inflammation index; neutrophil to lymphocyte ratio; platelet to lymphocyte ratio; hypertension
The study found that patients with high-value MS had higher levels of neutrophil, platelet, SII, NLR, and PLR, whereas lymphocyte counts were lower. These indices were all independently associated with exaggerated MS, with SII being superior to other indices for detecting the presence of exaggerated MS.
Background: The exaggerated morning blood pressure surge (MS) is associated with target organ damage and cardiovascular events. Systemic immune-inflammation index (SII) has been detected as a useful marker in tumors and cardiovascular diseases. The role of inflammation in the pathogenesis of hypertension is a well-known issue. We aimed to investigate whether there is an association between SII and exaggerated MS in newly diagnosed treatment-naive hypertensive patients. Material and Methods: In total, 343 newly diagnosed in clinical and 24-h ambulatory blood pressure (BP) monitoring treatment-naive hypertensive patients were included in this study. Morning surge was defined as the difference between morning BP, which was the mean of BP during 2 h after wake-up, and the lowest BP, which was the mean of three lowest BP during nighttime. A cutoff value of 52.1 mmHg was used to discriminate the high- and low value MS groups. SII was calculated based on neutrophil, platelet, and lymphocyte counts. Results: Neutrophil, platelet, SII, neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR) were higher, whereas lymphocyte counts were lower in the high-value MS than the low-value MS. These indices were all independently associated with exaggerated MS and SII was superior to all other indices for detecting the presence of exaggerated MS. SII was moderately correlated with morning BP surge (r: 0.489, p < 0.0001). Conclusion: SII was higher in patients with exaggerated MS and was independently associated with exaggerated MS. Furthermore, SII might be a better indicator than platelet, neutrophil, lymphocyte, NLR, and PLR for the presence of exaggerated MS.
