Correlation between Myocardial Strain Imaging by Two-dimensional Speckle Tracking and Coronary Angiographic Profile in Patients with Chronic 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
Background: Chronic coronary syndrome (CCS) constitutes 20%-30% of cardiac causes of chest pain. Deformation/Strain imaging is a sensitive marker of coronary artery disease (CAD) which detects subtle forms of ischemia in the form of strain. We aim to correlate global longitudinal and segmental strain with angiographic profile by using two-dimensional speckle tracking echocardiography (2D-STE). Materials and Methods: A prospective observational study was carried out on 150 subjects satisfying the inclusion criteria. Routine blood investigations, electrocardiogram, 2D echocardiography, and 2D-STE were performed. All subjects underwent coronary angiogram (CAG), and the severity of CAD was assessed by modified Gensini score (mGS). Global longitudinal strain (GLS) and segmental strain were correlated with mGS. Results: Mean age was 55.28 ± 8.94 years. Males constituted 67.3% of the study population. The most common symptom was angina (54%), and the most common risk factor was type 2 diabetes mellitus (37%). Mean left ventricular ejection fraction (LVEF) was 58.6%. The mean GLS in the Significant CAD group was -13.8% and in the Insignificant CAD group was -17.7% ( Conclusion: This study emphasizes the role of a simple, noninvasive transthoracic echocardiographic marker in predicting subclinical ischemia in CCS who have apparently normal LVEF. GLS correlates with the angiographic severity in CCS. The myocardial segmental strain correlates with angiographic territorial involvement. It is an independent predictor of significant CAD with good sensitivity and specificity.
