Assessment of left atrial mechanics and left ventricular functions using 3D speckle-tracking echocardiography in patients with inappropriate sinus tachycardia.

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
purposeInappropriate sinus tachycardia (IST) is defined as a sinus heart rate > 100 bpm at rest (with a mean 24-h heart rate > 90 bpm not due to primary causes) and is associated with distressing symptoms of palpitations. The effect of IST on left atrial (LA) and left ventricular (LV) myocardial dynamics is uncertain. Thus, the aim of this study was to identify early changes in LA mechanics and LV myocardial functions in patients with IST using 3D-STE.
methodsSixty patients with IST and 65 age- and gender-matched controls were enrolled into the study. Conventional 2D echocardiography and 3D-STE were performed, and LAS-r, LAS-active, LAS-passive, LAEF, LAEF-active, LAEF-passive, LV-GLS, LV-GCS, LV-GAS, and LV-GRS were obtained for every patient.
resultsThe LAS-r and LAS-active were significantly decreased in the IST group than in the control group (p < 0.001, p = 0.004, respectively). The multivariate logistic regression models revealed that LAS-r (p = 0.008, Odds ratio (OR) 5.98, 95% confidence interval (CI) 2.36-11.18), and LAS-active (p = 0.032, OR 2.16, 95% CI 1.97-4.69) were found to be independent factors for predicting IST.
conclusionsThe present study is the first to evaluate the left atrial mechanics and left ventricular functions in the patients with IST using 3D-STE. We found that IST had a negative effect on left atrial mechanics. According to our findings, we can say that IST is not a completely innocent, benign clinical condition, but rather, it causes subclinical left atrial dysfunction.
