BACKGROUND: European guidelines recommend the use of ticagrelor versus
clopidogrel in patients with ST elevation myocardial infarction (STEMI). This
recommendation is based on inconclusive results and subanalyses from clinical
trials. Few data are available on the effects of ticagrelor in a real-world
population. METHODS: To compare the effects of ticagrelor and clopidogrel in a
real-world STEMI population, we conducted a pre-post case-control study examining
all patients with STEMI included in the Cardio-STEMI Sanremo registry between
February 2011 and June 2013. Cases and controls were defined according to P2Y(12)
inhibitors, correcting the bias due to lack of randomization by propensity score
analysis. Ticagrelor was introduced in 2012 in both in-hospital and pre-hospital
settings independently of this study. RESULTS: Of the 416 patients enrolled in
the Cardio-STEMI registry, 401 with a definite diagnosis of STEMI were included
in this study. One hundred forty-two patients received ticagrelor and 259
received clopidogrel. Regarding clinical presentation and procedural data, those
in the ticagrelor group had lower CRUSADE scores (23 [14-36] vs 27 [18-38];
p = 0.015] but a higher proportion of radial access (33% vs 14%; p < 0.001),
percutaneous coronary intervention (PCI; 92% vs 81 %; p = 0.002) and primary
PCI ? 12 h (82% vs 66%; p = 0.001). The patients in the ticagrelor group had a
higher procedural success rate (100% vs. 96%; p = 0.044). There was no difference
in Bleeding Academic Research Consortium bleeding and in unadjusted incidence of
hospital major adverse cardiovascular events (MACE; cardiac death, myocardial
infarction, or stroke) but there was a significant reduction in unadjusted
cardiac hospital death in the ticagrelor group (0.7% vs 5.4%; p = 0.024). After
correcting for propensity score, hospital death (p = 0.22) and hospital MACE
(p = 0.96) did not differ in both groups. The unadjusted survival at 1 year after
STEMI was higher in the ticagrelor group (97.8% vs 87.8%; p = 0.024), and this
result was confirmed by propensity score analysis (hazard ratio = 0.29
[0.08-0.99]; p = 0.048). CONCLUSIONS: In this real-word propensity score
analysis, ticagrelor did not affect the risk of MACE during the hospital phase,
or the incidence of hospital bleeding in patients with STEMI. However, in this
mono-centric experience, ticagrelor resulted in improved 1-year survival, even
after correction by propensity score.
