    • Abstract:
      Objectives • The objective of this experiment was to investigate the relationship between the circadian rhythm of blood pressure and left ventricular hypertrophy (LVH) in patients with hypertension. Methods • A total of 500 hypertension patients with documented circadian rhythm of blood pressure were selected for this study. The researchers collected general patient data and fasting blood samples. The following parameters were measured within subgroups of hypertensive patients: age, sex ratio, BMI, fasting blood glucose, total cholesterol, triacylglycerol, HDL-C, LDL-C, duration of hypertension, antihypertensive drug usage, and statin intake. Results • The results of the study showed that LVH hypertension had a significantly higher proportion of grade 3 hypertension compared to non-LVH hypertension (P < .001). Additionally, LVH hypertension displayed higher mean systolic blood pressure levels over a 24-hour period (P = .002), during daytime (P = .029), and during nighttime (P < .001). The 24-hour pulse pressure (P < .001) and pulse pressure index (P = 0.001) were also significantly higher in patients with LVH hypertension. Furthermore, the rate of blood pressure decline at night was significantly lower in the LVH hypertension group compared to the control group (P < .001). B-type natriuretic peptide (BNP) levels (P = .034) and left ventricular mass index (LVMI) (P < .001) were significantly higher in patients with LVH hypertension compared to non-LVH patients. Conclusions • The findings of this study suggest a close association between hypertensive LVH and the weakening or disappearance of the circadian rhythm of blood pressure. It was also observed that the level of blood pressure classification and plasma BNP levels were increased in patients with LVH hypertension. [ABSTRACT FROM AUTHOR]
