Cocaine-Provoked Pulmonary Vein Thrombosis: A Potential Cause of Coronary Embolism and Cardiac Arrest.
Article in JACC. Case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundCoronary artery embolism (CAE) is an underrecognized cause of myocardial infarction, particularly in patients with limited coronary atherosclerosis. Pulmonary vein thrombosis (PVT) as an embolic source of CAE has rarely been described. CASE SUMMARY: A middle-aged female with known active cocaine use and Factor V Leiden mutation presented following out-of-hospital ventricular fibrillation cardiac arrest. Coronary angiography revealed thrombotic left circumflex artery occlusion without atherosclerosis. Computed tomography identified a nonocclusive left superior pulmonary vein thrombus as a possible embolic source. Drug-eluting stent implantation and apixaban were initiated; ticagrelor was de-escalated to clopidogrel given anticoagulation. Thrombus resolved at 12 weeks. DISCUSSION: Cocaine-provoked PVT causing CAE in inherited thrombophilia is a rare mechanism requiring embolic source evaluation and tailored management. TAKE-HOME MESSAGES: In patients with cryptogenic CAE, cocaine use with inherited thrombophilia should prompt PVT evaluation. When post-percutaneous coronary intervention antiplatelet therapy requires anticoagulation, P2Y12 de-escalation to clopidogrel reduces bleeding risk.
