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

backgroundTrimetazidine (TMZ) modulates cardiac metabolism, but its use in heart failure remains controversial. The aim of the study was to evaluate the effects of TMZ on exercise capacity, left ventricular ejection fraction (LVEF), mortality, and quality of life in stable patients with heart failure with reduced left ventricular ejection fraction (HFrEF).

methodsForty-five patients with stable advanced HFrEF treated with optimal medical therapy were randomized in a prospective, single-center, open-label, cross-over study of trimetazidine (35 mg b.i.d.) on top of standard medical therapy or standard pharmacotherapy for two periods of 30 days and one period of 6 months. Initially and at the end of each period all patients underwent the following: exercise testing, six-minute walk test (6MWT), two-dimensional-echocardiography, and quality of life assessment.

resultsThe mean age of patients was 58.2 ± 10.6 years. Etiology of HFrEF was ischemic in 66.6% of patients. After 6 months no significant changes were observed in either group with regards to peak VO₂ uptake, 6MWT, LVEF, or quality of life. TMZ had no effect on mortality or cardiovascular events.

conclusionsThe additional use of TMZ on top of standard medical therapy in stable advanced HFrEF patients was not associated with significant changes in mortality, exercise capacity, LVEF, or quality of life.
