Abstract
Objective: To analyze the characteristics of ambulatory blood pressure in elderly patients with hypertension and find out the risk factors of abnormal circadian rhythm. Methods: According to the circadian rhythm of patients’ blood pressure, they were divided into Group A, Group B and Group C, and all the data of hypertension patients in this study were collected, including age, gender, BMI, smoking, drinking, basic diseases (diabetes, cerebrovascular disease, hyperlipidemia, etc.), fasting blood glucose, ambulatory blood pressure (24-hour mean systolic pressure, 24-hour mean diastolic pressure, daytime mean systolic pressure and daytime mean diastolic pressure). Results: There were significant differences in mean systolic blood pressure and mean diastolic blood pressure at night among Group A, Group B and Group C (P < 0.05). Age, hyperlipidemia and fasting blood glucose were risk factors for circadian rhythm abnormality (P < 0.05), and 24-hour urinary sodium was a protective factor for circadian rhythm abnormality (P < 0.05). Conclusion: Age, hyperlipidemia and fasting blood glucose are risk factors for circadian rhythm abnormality (P < 0.05), and 24-hour urinary sodium is a protective factor for circadian rhythm abnormality (P < 0.05).
