Diastolic stress echocardiography in Japanese elderly patients: prevalence and features of patients with elevated left ventricular filling pressure after treadmill stress.
Article in Journal of echocardiography, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
purposeThis study attempted to evaluate the prevalence and features of elderly patients with elevated post-exercise left ventricular (LV) filling pressure in Japan.
backgroundPrevious studies have validated that LV filling pressure during exercise can be estimated non-invasively by the Doppler index of diastolic filling (E/E'), and diastolic stress echocardiography has been promoted. There is limited information about diastolic stress echocardiography in Japan.
methodsThree hundred ten elderly patients aged ≥60 years who underwent treadmill stress echocardiography were studied. Patients with ischemic response were excluded. Doppler measurements were made before and immediately after the treadmill stress, and patients were divided into two groups regarding post-exercise E/E' with cutoff values of 15. Clinical and echocardiographic characteristics were compared between the two groups.
resultsOne-third (33.9%) of the patients presented elevated post-exercise LV filling pressure indicated by E/E' ≥15. Patients with an elevated post-exercise E/E' were older (p = 0.0052), had a greater mean body mass index (p = 0.0459), were more likely to have an abnormal glucose tolerance (p = 0.0059), had a greater LV mass index (p = 0.0383), a greater left atrial volume index (p = 0.0042), and a higher E/E' value at rest (p < 0.0001).
conclusionOne-third of the Japanese elderly patients who were referred for treadmill stress echocardiography and not limited by ischemia presented elevated post-exercise LV filling pressure indicated by E/E' ≥15. These patients are likely to have clinical and echocardiographic characteristics of heart failure with preserved ejection fraction.
