PLATO was a multicentre, randomized, double-dummy, double blind trial conducted to determine if ticagrelor is superior to clopidogrel for the prevention of vascular events and death in patients with ACS and the study demonstrated a significant reduction of the composite primary endpoint of cardiovascular death, MI and stroke in the ticagrelor group. This is a practice-changing study with ticagrelor recently replacing clopidogrel in our code STEMI protocol but as a group we identified that the drug is significantly underutilized in cases of NSTEMI and UA, perhaps due to cost.

Epi Lesson – Survival Analyses

Survival analyses are used in clinical trials that follow patients over time for primary outcomes such as death, relapse, adverse drug reaction, or development of a new disease. The follow-up time may range from hours to years and a different set of statistical procedures are employed to analyze the data. Terms frequently seen in papers with survival analyses include Cox proportional hazard model, hazard ratio, Kaplan-Meir curve.
