The prevalence of hypertension in patients with CKD in China is high but the control rate is low. Compared with the single blood pressure measurement method of the blood pressure of the office, ambulatory blood pressure monitoring (ABPM) can reflect the overall situation of 24-hour blood pressure, dynamic fluctuation degree and circadian rhythm change more completely and objectively. Studies have shown that patients with CKD with hypertension have their own uniqueness through ABPM measurement, and nocturnal hypertension is the main cause of poor blood pressure control. Further studies have shown that nocturnal hypertension is an independent and more effective prognostic indicator of death and CVD in patients with hypertension. Evidence from European and American countries suggests that in the CKD population, elevated nighttime blood pressure is more predictive of CKD progression or CVD than daytime blood pressure. Compared with countries such as Europe and the United States, there are differences in the causes, genetic background and daily behaviors of kidney disease in our population. It is urgent to investigate the predictive value of nocturnal hypertension for renal end point and CVD in CKD population in China. To this end, our study found for the first time that CKD patients generally have changes in nocturnal blood pressure patterns, and the anti-dope type blood pressure pattern is closely related to the target organ damage. Our further study found that the incidence of nocturnal hypertension in Chinese patients with CKD is more than 50%, and compared with non-dipping blood pressure, patients with nocturnal hypertension have more serious target organ damage, which is independent risk factors for all-cause death, cardiovascular death, renal events, and cardiovascular events in patients with CKD. These preliminary results suggest the role of nocturnal hypertension in the prognosis of CKD patients in China, but there are still the following questions: Is the occurrence of nocturnal hypertension in CKD patients related to certain gene expression? This project intends to perform whole-genome exon sequencing and analysis on CKD patients with nocturnal hypertension to determine the genetic mechanism of CKD patients with nocturnal hypertension. The completion of the subject will reveal the genetic characteristics of CKD patients with nocturnal hypertension, and provide a basis for the precise prevention and treatment of chronic kidney disease hypertension.
