Angiotensin (1-7) and Apelin co-therapy: New strategy for heart failure treatment of rats.
Article in Anatolian journal of cardiology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
objectiveIsoproterenol (ISO)-induced heart failure is a standardized model for the study of beneficial effects of various drugs. Both apelin and angiotensin 1-7 have a cardiac protective effect. We assumed that co-therapy with apelin and angiotensin 1-7 (Ang (1-7)) may have synergistic cardioprotective effects against isoproterenol-induced heart failure. Methods The animals were randomly assigned to one of eight groups of seven animals in each group as follows: (1) control I (saline; IP injection) (1) control II (saline; via mini-osmotic pump) (3) ISO (5 mg/ kg; IP), (4) Apelin (20μg/ kg; IP), (5) Ang (1-7) (30 μg/kg/day; via mini-osmotic pump), (6) Apelin+ISO, (7) Ang (1-7)+ISO, (8) Apelin+Ang (1-7)+ISO. Rat myocardial injury was induced by intraperitoneal injection of 5mg/kg of ISO for ten days. Apelin and Ang (1-7) were administered 30 minutes before ISO injection.
resultsA decrease in systolic blood pressure (SBP; p<0.001), diastolic blood pressure (DBP; p<0.05), left ventricular systolic pressure (LVSP; p<0.001), left ventricular contractility (dP / dt max; p<0.001), relaxation (dP / dt min; p<0.001) and an increase in left ventricular end-diastolic pressure (LVEDP; p<0.001) were observed in ISO-treated rats. Plasma LDH and myocardial and plasma MDA were higher in the ISO heart than in controls (P<0.001). Histopathological examination of cardiac tissue showed myocardial fibrosis and leukocyte infiltration in ISO-treated rats as compared to control. Co- therapy with apelin and Ang (1-7) was more effective than either agent used alone in restoring these parameters to that of control rats.
conclusionThe results of this study showed that the combination of apelin and ang (1-7) had a more cardioprotective effect than either used alone against ISO-induced heart failure, and co-therapy may be a useful treatment option for myocardial injuries and heart failure.
