Predictive value of speckle tracking technique for coronary artery stenosis in patients with coronary heart disease.
Article in American journal of translational research, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 observe the predictive value of speckle tracking technique (STI) for the degree of coronary artery stenosis in patients with coronary heart disease (CHD).
methodsThe clinical data of 120 patients with coronary artery stenosis admitted to Affiliated Hospital of Chengde Medical University from Feb. 2022 to Sep. 2022 was analyzed retrospectively. The other 63 patients who sought for medical help because of chest pain underwent Coronary Arteriography (CAG) examination during the same period but with Gensini score > 0 were selected as the control group. Coronary artery stenosis was divided into three subgroups according to the coronary Gensini score: mild, moderate, and severe stenosis. Routine ultrasound and STI techniques were performed in all patients. In addition, left ventricular global radial peak systolic strain (GRS), left ventricular global longitudinal peak systolic strain (GLS), left ventricular global peak systolic strain (GAS) and left ventricular global circumferential peak systolic strain (GCS) were measured and compared between the two groups and among the three subgroups.
resultsThere were no marked differences identified in conventional ultrasound parameters between the coronary artery stenosis group and control group, but the absolute values of GLS, GRS, GCS, and GAS were lower in the former group compared to control group; and the severe group had the lowest levels of above indexes, followed by moderate group, then mild group and control group (all P < 0.05). The results showed that the area under the curve (AUC) for GLS, GRS, GCS, and GAS in diagnosing coronary artery stenosis were 0.973, 0.933, 0.947, and 0.901, respectively. The AUCs of GLS, GRS, GCS, and GAS for the diagnosis of moderate/severe coronary artery stenosis were 0.968, 0.908, 0.901, and 0.942, respectively, with GAS and GLS assessed with the largest AUC values and higher sensitivity and specificity than other parameters.
conclusionThe global longitudinal strain of left ventricle obtained by STI technique was more sensitive to coronary artery stenosis than that by ultrasound technique, and it had a higher predictive value for coronary artery stenosis.
