MedicalResearch.com: What is the background for this study?

Response: To date, it remains unclear whether disrupted blood pressure (BP) circadian rhythm is associated with adverse outcomes independent of nighttime BP.

The JAMP study includes 6359 outpatient population who had ambulatory BP monitoring to evaluate the association between both nocturnal hypertension and nighttime BP dipping patterns and the occurrence of cardiovascular events in patients with hypertension.

MedicalResearch.com: What are the main findings?

Response: This largest prospective ABPM study to date showed that nighttime blood pressure and a riser pattern of nighttime blood pressure were significantly and independently associated with the risk of Atherosclerotic Cardiovascular Disease and Heart Failure events.

MedicalResearch.com: What should readers take away from your report?

Response: The earlier and the lower blood pressure control throughout a 24-hour period including nighttime is important for reducing cardiovascular events especially for the high-risk patients. Earlier detection and management of nocturnal hypertension will contribute to reduce the risk of Atherosclerotic Cardiovascular Disease and Heart Failure events.

MedicalResearch.com: What recommendations do you have for future research as a result of this work?

Response: An intervention study to reduce nighttime blood pressure level <120 mmHg. 

MedicalResearch.com: Is there anything else you would like to add?

Response: This study was financially supported in part by a grant from the Foundation for the

Development of the Community (Tochigi).
