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

Heart failure with preserved ejection fraction (HFpEF) is increasing in prevalence and has no guideline-recommended therapy, related in part to a lack of mechanism. Traditionally, HFpEF was thought to be secondary to afterload overload due to systemic hypertension; however, accumulating evidence suggests that HFpEF continues to worsen despite adequate control of blood pressure. Emerging data support the suggestion that myocardial ischemia secondary to coronary microvascular dysfunction could be the new paradigm pathophysiology. Several prospective, observational cohort studies indicate that the outcomes of patients with microvascular dysfunction, after an interval of several years, are dominated by HFpEF hospitalizations. Further, the most prevalent clinical phenotype (eg older women with multiple comorbidities) of patients with HFpEF resembles those with coronary microvascular dysfunction, albeit older. In this review, we provide in-depth insight about this emerging HFpEF paradigm, discuss potential therapeutic implications of this pathophysiology, and summarize some important knowledge gaps.
