Conclusions: Telmisartan vs. Placebo 1.Telmisartan reduces the primary outcome by 8% (P=0.22), but reduces significantly the main secondary outcome of CV death, MI or stroke by 13% (P=0.048). 2.There is no impact on heart failure events with telmisartan. 3.Telmisartan is well tolerated and there is no excess of adverse events
22
TRANSCEND and PROFESS Meta-Analysis 1.Clear reduction in the relative risk of the composite of CV death, MI or stroke by 9% (p=0.013), with little effect in the first 6 months after randomization, but a 15% RRR after 6 months (significant heterogeneity over the two time periods). 2.Neutral effect of telmisartan on heart failure events, which is surprising (OR of 1.00, 95% CI of 0.85 to 1.17), but this is consistent with the results of HF in ONTARGET (more events with telmisartan compared to ramipril). 3.Lower rates of MI and stroke.
