|Abstract:||Correlation between blood pressure (BP) and target organ damage, cardiovascular disease (CVD) risk, and long-term prognosis is greater for ambulatory BP monitoring (ABPM) than daytime in-clinic measurements. Additionally, consistent evidence of numerous studies substantiates the ABPM-determined asleep BP mean is an independent and stronger predictor of CVD risk than the awake or 24h means. Hence, cost-effective adequate control of sleep-time BP is of marked clinical relevance. Ingestion time, according to circadian rhythms, of hypertension medications of six different classes and their combinations significantly impacts their beneficial and/or adverse effects. For example, because the high-amplitude circadian rhythm of the renin-angiotensin-aldosterone system activates during nighttime sleep, bedtime versus morning ingestion of angiotensin-converting enzyme inhibitors and angiotensin receptor blockers (ARB) better controls the asleep BP mean, with additional benefit, independent of medication terminal half-life, of converting the 24h BP profile into more normal dipper patterning. The MAPEC Study, first prospective randomized treatment-time investigation testing the worthiness of bedtime chronotherapy with ≥1 conventional hypertension medications to specifically target attenuation of asleep BP, demonstrated, relative to conventional morning therapy, significant reduction of CVD risk: adjusted hazard ratio (HR) of total CVD events (HR=0.39 95%CI [0.29-0.51]; P<0.001) and major CVD events, i.e., CVD deaths, myocardial infarctions, and ischemic and hemorrhagic strokes (HR=0.33 [0.19-0.55]; P<0.001). CVD risk reduction was strongest when bedtime treatment included an ARB. The MAPEC Study not only documents the asleep BP mean is the most significant prognostic marker of CVD and stroke morbidity and mortality, but it also substantiates attenuation of the asleep BP mean by a bedtime hypertension treatment strategy with the entire daily dose of ≥1 hypertension medications significantly reduces CVD risk, both in the general hypertension population and in patients of greater vulnerability and enhanced CVD risk, i.e., those diagnosed with chronic kidney disease, diabetes, and resistant hypertension.|
