Detection of left ventricular asynchrony and its relationship with the Tei index in patients with coronary artery ectasia.

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
objectiveTo evaluate left ventricular (LV) systolic asynchrony and its relationship with the Tei index using tissue Doppler imaging (TDI); and to evaluate the relationship of thrombolysis in myocardial infarction frame count (TFC) and Tei index with LV asynchrony in patients with coronary artery ectasia (CAE).
methodsA total of 50 CAE patients and 40 control subjects were evaluated. Diagnosis of CAE was made angiographically and TFC was calculated. LV systolic and diastolic function was assessed by conventional echocardiography and TDI. Evaluation of intra-LV systolic asynchrony was performed using tissue synchronization imaging (TSI).
resultsIn patients with CAE, the Tei index was significantly higher than in controls (0.63±0.12 versus 0.52±0.12; P<0.001). LV systolic asynchrony parameters of TSI including SD of the peak tissue velocity (Ts) of the 12 LV segments (Ts-SD-12), maximal difference in Ts between any two of the 12 LV segments (Ts-12), SD of the Ts of the six basal LV segments (Ts-SD-6), maximal difference in Ts between any of the six basal LV segments (Ts-6) were significantly lengthened in patients with subclinical hypothyroidism compared with controls (P<0.001, P<0.001, P<0.001 and P<0.001, respectively). In addition, a positive correlation was found between Ts-SD-12 and the Tei index in patients with CAE (r=0.841; P<0.001) and mean TFC was positively correlated with Ts-SD-12 and the Tei index (r=0.345; P=0.013 and r=0.291; P=0.021, respectively).
conclusionPatients with CAE exhibit evidence of LV systolic asynchrony according to TSI. LV systolic asynchrony is related to the Tei index and mean TFC. Furthermore, the Tei index is an independent risk factor for LV systolic asynchrony.
