The association between tissue doppler-derived E/(e's') ratio and coronary atherosclerosis severity measured by the SYNTAX score in patients with non-ST elevation-acute coronary syndrome.

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
backgroundThe prognosis of patients hospitalized with non-ST elevation-acute coronary syndrome (NSTE-ACS) is typically determined by the existence and severity of myocardial necrosis and left ventricular (LV) remodeling.
aimThe present study was to assess the association between the E/(e's') ratio and the coronary atherosclerosis severity, measured by the SYNTAX score, in patients with NSTE-ACS.
methodsUtilizing a descriptive correlational research design, this study was prospectively conducted on 252 patients with NSTE-ACS, undergoing an echocardiography to determine the left ventricular ejection fraction (LVEF), the left atrial (LA) volume, the pulsed-wave (PW) Doppler-derived transmitral early (E) and late (A) diastolic velocities, and the tissue Doppler (TD)-derived mitral annular early diastolic (e') and peak systolic (s') velocities. After that, a coronary angiography (CAG) was performed, and the SYNTAX score was calculated.
resultsThe patients were divided into two groups, viz., those with the E/(e's') ratio < 1.63 and the cases with the ratio ≥ 1.63. The results revealed that the patients with a high ratio were older, had a higher prevalence of females, a SYNTAX score ≥ 22, and a lower glomerular filtration rate than those with a low ratio (p-value < 0.001). Besides, these patients had larger indexed LA volume and lower LVEF than others (p-value: 0.028 and 0.023, respectively). Furthermore, the multiple linear regression outcomes established a positive independent association between the E/(e's') ratio ≥ 1.63 (B = 5.609, 95% CI 2.324-8.894, p-value = 0.001) and the SYNTAX score.
conclusionThe study results demonstrated that the patients hospitalized with NSTE-ACS and the E/(e's') ratio ≥ 1.63 had worse demographic, echocardiographic, and laboratory profiles and a higher prevalence of a SYNTAX score ≥ 22 than those with a lower ratio.
