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

backgroundTakotsubo cardiomyopathy (TTC) is increasingly well-recognized as a cause of chest-pain syndromes, especially in aging females. The most common complications of TTC occur in the first 24 hours post onset of symptoms and include shock and/or arrhythmias. HYPOTHESIS: We tested the hypothesis that the severity of early hypotension in TTC reflects the extent of myocardial involvement and dysfunction.

methodsIn 80 consecutive TTC patients, correlates of blood pressure on the day of admission were sought via univariate followed by multivariate analysis.

resultsMean systolic blood pressure (SBP) on day 1 was 120 ± 24 (SD) mm Hg. During the first 3 days of admission, 39% of patients had SBP <90 mm Hg, and 9% died and/or required intra-aortic balloon pump insertion. The extent of release of N-terminal pro-brain natriuretic peptide, with its potential correlate of associated vasodilator activity, varied inversely with pulmonary-artery saturation, a measure of cardiac output. However, there was no significant relationship between normetanephrine release and SBP. On multivariate analyses there was no significant relationship between SBP and (1) wall-motion score index (as an index of left-ventricular systolic dysfunction) or (2) T2 enhancement on cardiac magnetic resonance imaging and peak N-terminal pro-brain natriuretic peptide (as indices of myocardial inflammation).

conclusionsAlthough severe hypotension and shock occur commonly during acute stages of TTC, these complications are multifactorial in origin, probably representing a combination of impaired inotropic state and vasodilatation. Importantly, initial hypotension does not imply severe left ventricular inflammation or systolic dysfunction.
