Ticagrelor effectively inhibits platelet aggregation in comatose survivors of cardiac arrest undergoing primary percutaneous coronary intervention treated with mild therapeutic hypothermia.
Observational study in Cardiology journal, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundMild therapeutic hypothermia (MTH) is believed to reduce the effectiveness of antiplatelet drugs. Effective dual-antiplatelet therapy after percutaneous coronary intervention (PCI) is mandatory to avoid acute stent thrombosis. The effectiveness of ticagrelor in MTH-treated out-of-hospital cardiac arrest (OHCA) survivors is still a matter of debate. The aim of the study was to evaluate the impact of MTH on the platelet-inhibitory effect of ticagrelor in comatose survivors of OHCA treated with primary PCI.
methodsEighteen comatose survivors of OHCA with acute coronary syndrome undergoing immediate PCI treated with MTH were compared with 14 patients with uncomplicated primary myocardial infarction after PCI, matched for gender and age, in a prospective, single-center, observational study. Platelet aggregation was evaluated using VerifyNow P₂Y₁₂ point-of-care testing at 3 time points: admission (T₀), during MTH (T₁), and 48-72 h after rewarming (T₂).
resultsTicagrelor effectively inhibits platelet aggregation in OHCA patients subjected to MTH and in all patients in the control group. The effectiveness of ticagrelor did not differ between the MTH group and the control group (p = 0.581). In 2 cases in the MTH population, the platelet response to ticagrelor was inadequate, and in one of them it remained insufficient during the re-warming phase. There was no stent thrombosis in these patients.
conclusionsThe present study confirmed the effectiveness of ticagrelor to inhibit platelets in myocardial infarction patients after OHCA treated with primary PCI undergoing hypothermia. The use of cooling was not associated with an increased risk of stent thrombosis.
