Paris: There is not any proof that blood pressure-lowering medication build up the danger of most cancers, in step with probably the most intensive learn about carried out at the matter. The late-breaking analysis is gifted at ESC Congress 2020.
“Our results should reassure the public about the safety of antihypertensive drugs with respect to cancer, which is of paramount importance given their proven benefit for protecting against heart attacks and strokes,” stated learn about creator Emma Copland, an epidemiologist on the University of Oxford, UK.
A possible link between blood pressure medication and most cancers has been debated for greater than 40 years. The proof for an higher or reduced chance of most cancers with the usage of antihypertensive medication has been inconsistent and conflicting.
This was once the most important learn about on most cancers results in individuals of randomised trials investigating antihypertensive medication – round 260,000 other people in 31 trials. Investigators of all trials had been requested for info on which individuals advanced most cancers.
Much of this knowledge has no longer been printed earlier than, making the present research probably the most detailed but. Five antihypertensive drug categories had been investigated one at a time: angiotensin-converting enzyme (ACE) inhibitors, angiotensin II receptor blockers (ARBs), beta-blockers, calcium channel blockers (CCBs), and diuretics.
The investigators estimated the impact of every drug elegance at the chance of growing any form of most cancers, of demise from most cancers, and of growing breast, colorectal, lung, prostate and pores and skin cancers.
They additionally tested whether or not there have been any variations in step with age, gender, frame dimension, smoking standing, and earlier antihypertensive medication use earlier than collaborating within the trial.
During a median of 4 years, there have been round 15,000 new diagnoses of most cancers. The researchers discovered no proof that the usage of any antihypertensive drug elegance higher the danger of most cancers.
This discovering was once constant irrespective of age, gender, frame dimension, smoking standing, and earlier antihypertensive medication use. Each drug elegance was once when compared in opposition to all different keep watch over teams, together with placebo, usual remedy, and different drug categories.
There was once no vital impact on someone drug elegance on total most cancers chance. The danger ratio (HR) for any most cancers was once 0.99 (95 % self assurance period [CI]) 0.94-1.04) with ACE inhibitors, 0.97 (95 % CI 0.93-1.02) with ARBs, 0.98 (95 % CI 0.89-1.08) with beta-blockers, 1.06 (95 % CI 1.01-1.11) with CCBs and 1.01 (95 % CI 0.95-1.07) with diuretics.
In statistical phrases, those impact sizes weren’t considerably other from every different, so there was once no proof of an higher chance of most cancers with any of the drug categories.
Similarly, there was once no proof that any form of antihypertensive medication had an impact at the likelihood of growing breast, colorectal, lung, prostate, or pores and skin most cancers.
When individuals had been adopted all the way through the process every trial, there was once no indication that the danger of most cancers higher with longer period of use of those remedies.
“Our study has addressed an ongoing controversy about whether antihypertensive medication increases the risk of developing cancer. We used the largest individual-level randomised evidence on antihypertensive medication to date and provide evidence for the safety of blood pressure-lowering drugs in relation to cancer,” Copland stated.
