Platelet Function Testing to Guide Cangrelor Dosing in Patients with Temporary Mechanical Circulatory Support or as a Bridge to Procedure.

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
Cangrelor is a rapid-acting, intravenous P2Y12 inhibitor that can be used in patients after percutaneous coronary intervention who require mechanical circulatory support or as a bridge to procedure. We retrospectively reviewed adult patients who received platelet function testing (PFT) with the VerifyNow P2Y12 assay while on cangrelor from March 2021 through November 2022. All patients were initiated on 0.75 mcg/kg/min of cangrelor with P2Y12 reaction unit (PRU) values collected 12-24 h after initiation. Cangrelor doses were adjusted per protocol to maintain PRU values of 85-208. A total of 42 patients were included. Thirty-eight patients (90.5%) required temporary mechanical circulatory support while on cangrelor, and 4 patients (9.5%) received cangrelor as a bridge to procedure. The median cangrelor maintenance dose was 0.5 (interquartile range [IQR]: 0.375-0.75) mcg/kg/min, and the median time in therapeutic range with a PRU value between 85 and 208 was 66.6% (IQR: 39.6%-100%). No patients experienced stent thrombosis. A composite major adverse cardiovascular event occurred in 4 patients (9.5%), and major bleeding occurred in 16 patients (38.1%). Compared to empiric cangrelor dosing of 0.75 mcg/kg/min, PFT-guided cangrelor dose adjustment was associated with a median drug cost savings of $1605.60 (IQR: $0-4281.56). Utilizing PFT with cangrelor may allow for lower, individualized dosing while preventing stent thrombosis.
