The timing of administration of blood stress remedy doesn’t have an effect on the outcomes

Taking blood stress decreasing remedy within the night didn’t scale back the danger of cardiovascular occasions or dying in comparison with taking it within the morning, in keeping with original analysis introduced at this time in a hotline session on the ESC Congress 2024.

There’s proof that elevated blood stress at evening is related to an elevated danger of heart problems. Nonetheless, research that gain examined the results of administering antihypertensive medicines at evening gain proven blended outcomes. On this meta-analysis, we gain pooled all examine information and concluded that the timing of administration doesn’t have an effect on the outcomes.”

A scientific overview and meta-analysis was carried out, together with all parallel-group randomized managed trials (RCTs) evaluating nighttime and morning administration of any antihypertensive remedy. Research needed to gain at the least one cardiovascular final result of curiosity, with follow-up of ≥500 affected person years per group and a median follow-up of ≥12 months. Research had been assessed utilizing the Cochrane Threat of Bias 2 software.

The first endpoint was main opposed cardiovascular occasions (MACE, a composite of dying from any trigger, non-fatal myocardial infarction, non-fatal stroke, and coronary heart failure exacerbation). Secondary endpoints included particular person parts of MACE, all-cause hospitalizations, and particular security occasions (fractures, glaucoma-related occasions, and cognitive deterioration).

5 RCTs involving 46,606 sufferers had been included – BedMed2, BedMed-Frail2, TIME3, Hygia4 and MAPEC5. The BedMed, BedMed-Frail and TIME trials had been judged to gain a low total danger of bias, whereas there have been some issues about bias in Hygia and MAPEC, notably with regard to the randomisation course of.

In all 5 research, the incidence of MACE was not influenced by night or morning administration (hazard ratio [HR] 0.71; 95% confidence interval [CI] 0.43–1.16). In a sensitivity evaluation for danger of bias, the HR for MACE for night versus morning dosing was 0.94 (95% CI 0.86–1.03) within the three research the place low bias was discovered and 0.95 (95% CI 0.86–1.03) within the two research the place there was concern for bias.

There was no inequity in total mortality between night and morning dosing (HR 0.77; 95% CI 0.51-1.16). All different secondary endpoints had been additionally unaffected by night or morning dosing, together with fractures, glaucoma occasions, and cognitive occasions.

“The outcomes of the meta-analysis present conclusive proof that there isn’t any inequity between night and morning dosing. Sufferers ought to acquire their once-daily antihypertensive remedy on the time that most closely fits their preferences and circumstances,” concluded Professor Turgeon.
