Very recently I have noticed hypertension patients taking their medications at bedtime. Now I know why.
Taking antihypertensive medication at bedtime led to an almost halving of cardiovascular events in a new study.
The Hygia Chronotherapy Trial is the largest ever study to investigate the effect of the time of day when people take their antihypertensive medication on the risk of cardiovascular events.
The trial randomly assigned 19,084 patients to take their medication on waking or at bedtime and followed them for an average of 6 years.Results showed that patients who took their pills at bedtime had a 45% reduction in overall cardiovascular events. This included a 56% reduction in cardiovascular death, a 34% reduction in myocardial infarction (MI), a 40% reduction in coronary revascularization [bypass surgery and angioplasty/stenting], a 42% reduction in heart failure, and a 49% reduction in stroke, all of which were statistically significant.
“We showed that if blood pressure is elevated during sleep then patients have increased cardiovascular risk regardless of daytime pressure, and if blood pressure during sleep is normal then cardiovascular risk is low even if the [doctor’s] office pressure is elevated,” Hermida said.
Results showed that during the 6.3-year median patient follow-up, 1752 participants experienced the primary cardiovascular disease (CVD) outcome (a composite of CVD death, MI, coronary revascularization, heart failure, or stroke).
Drug classes at physicians’ disposal were ARBs (angiotensin receptor blockers), calcium channel blockers, ACE inhibitors, and diuretics. Preventative effects were most pronounced for ARBs and ACE inhibitors.
Don’t change your BP medication dosing until you check with your personal physician.

Did you know most heart attacks occur in the morning, and those tend to be the most serious?
