Concomitant Systolic and Diastolic Doppler Alternans: An Ominous Sign of Left Ventricular Dysfunction.

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
Pulsus alternans, defined by an arterial pulse alternating between strong and weak beats, often signify severe left ventricular dysfunction. Detectable on physical examination or by echocardiography, this phenomenon highlights substantial cardiac compromise. We discuss a case involving a 59-year-old male with non-ischemic cardiomyopathy who was admitted for acute congestive heart failure. The echocardiogram revealed severe left ventricular dysfunction with systolic and diastolic beat-to-beat variations in blood flow on Doppler, a phenomenon known as Doppler alternans. Notably, these echocardiographic findings preceded any clinical signs, leading to a timely escalation in care. This case emphasizes the critical role of echocardiography in assessing ventricular function and providing prognostic insights that can influence management strategies.
