Those with a disrupted circadian blood pressure rhythm - or higher blood pressure at night than during the day - had a 48% higher risk for heart disease and were nearly three times as likely to experience heart failure, the data showed.Ĭircadian rhythms are the body's natural, internal process that regulates a person's sleep-wake cycle and repeats with each rotation of the Earth, or roughly every 24 hours, according to the American Heart Association.īlood pressure typically fluctuates with a pattern that follows the circadian rhythms, with a peak in the early morning hours and a low during sleep, the researchers said. Nearly every participant recorded 20 daytime and seven nighttime automated blood pressure measurements.īy the end of the study period, participants experienced a total of 306 cardiovascular events, including 119 strokes, 99 diagnoses of coronary artery disease and 88 diagnoses of heart failure.
