Blood pressure spikes at night up CVD risk
A disrupted circadian rhythm with a 'riser' pattern at night is associated with increased risk of cardiovascular disease and heart failure: Japanese study
People who experience elevated nighttime blood pressure are at increased risk of cardiovascular events and heart failure, a Japanese study suggests.
Researchers examined data on almost 6,360 patients with at least one risk factor for cardiovascular events but no symptoms of cardiovascular disease at baseline.
Participants had a mean age of 68.6 years at baseline, when they underwent 24-hour ambulatory BP monitoring.
After a mean follow-up of 4.5 years, there were 306 cardiovascular events, including 119 strokes, 99 incidents of coronary artery disease and 88 cases of heart failure.
