1 · What the graph read from it

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.

2 · The registry

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

backgroundIncreasing evidence suggests that angiotensin converting enzyme (ACE) inhibitors exert antithrombotic effects. Based on the assumption of differential effects of various ACE inhibitors on coagulation, the aim of the present study was to evaluate the coagulative activities of cardiovascular (CV) patients treated with either ramipril, captopril, and enalapril, and to compare these with patients treated with established antithrombotics such as aspirin (ASA) and clopidogrel or none of these medication.

methodsBlood samples of 320 CV patients with coronary artery disease and/or arterial hypertension were analyzed by wholeblood aggregometry. Platelet aggregation was determined by measuring the increase in impedance across paired electrodes in response to the aggregatory agents collagen and adenosine diphosphate (ADP), respectively. These data were correlated with medical treatment.

resultsPlatelet aggregation was attenuated ex vivo by ramipril and captopril as well as by ASA and clopidogrel. While collagen-induced platelet aggregation was significantly reduced by ramipril (35%; P <0.01) and captopril (27%; P = 0.01), no change was seen with enalapril. After induction with ADP, platelet aggregation was reduced in the presence of captopril therapy by 46% (P <0.05). There was a trend of inhibition with ramipril (32%, P = n.s.), whereas no antithrombotic effect was seen with enalapril.

conclusionOur findings demonstrate that ACE inhibitors decrease platelet aggregation ex vivo. The differential antiaggregatory profile may explain at least in part different effects of ACE inhibitors on cardiovascular endpoints as observed in large clinical trials.
