Night administration of blood stress (BP)-lowering drugs didn’t scale back the chance of cardiovascular occasions or demise in contrast with morning administration, in keeping with late-breaking analysis introduced in a Scorching Line session right this moment at ESC Congress 2024.
Proof means that higher-than-normal ranges of BP at evening are related to an elevated danger of cardiovascular occasions. Nonetheless, trials which have assessed the influence of administering BP-lowering drugs at evening have proven combined outcomes. On this meta-analysis, we gathered collectively the entire trial knowledge and concluded that the timing of dosing doesn’t have an effect on outcomes.”

A scientific overview and meta-analysis was undertaken that included all parallel-group randomized managed trials (RCTs) evaluating night-time and morning administration of all BP-lowering drugs. Research needed to have not less than one cardiovascular final result of curiosity, with follow-up of ≥500 patient-years per group and median follow-up ≥12 months. Trials had been assessed utilizing the Cochrane Danger of Bias 2 software.
The first endpoint was main hostile cardiovascular occasions (MACE, a composite of demise from any trigger, non-fatal myocardial infarction, non-fatal stroke and coronary heart failure exacerbation). Secondary endpoints included particular person elements of MACE, all-cause hospitalization and particular security occasions (fractures, glaucoma-related occasions and worsening cognition).
5 RCTs had been included with 46,606 sufferers – BedMed,2 BedMed-Frail,2 TIME,3 Hygia4 and MAPEC.5 The BedMed, BedMed-Frail and TIME trials had been judged to be at total low danger of bias, whereas there have been some bias issues with Hygia and MAPEC, notably concerning the randomization course of.
Throughout the 5 trials, the incidence of MACE was not affected by night vs. morning dosing (hazard ratio [HR] 0.71; 95% confidence interval [CI] 0.43-1.16). In a sensitivity evaluation by danger of bias, the HR was 0.94 (95% CI 0.86-1.03) for MACE with night vs. morning dosing within the three trials judged to have low bias and 0.43 (95% CI 0.26-0.72) within the two trials with bias issues.
There was no distinction in all-cause mortality for night and morning dosing (HR 0.77; 95% CI 0.51-1.16). Equally, all different secondary endpoints weren’t affected by night vs. morning dosing, together with for fractures, glaucoma occasions and cognitive occasions.
“Outcomes from the meta-analysis present conclusive proof that there isn’t any distinction between night and morning dosing. Sufferers ought to take their once-daily BP-lowering drugs at no matter time most accurately fits their preferences and circumstances,” concluded Professor Turgeon.
