Evaluation of myocardial perfusion and systolic function in patients with coronary heart disease by myocardial contrast echocardiography and 2-dimensional speckle tracking imaging.

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
objectivesThe high prevalence and high fatality rate of coronary heart disease seriously endanger the safety of human life. The key to its treatment is to restore the perfusion of the narrowed coronary arteries as soon as possible. Two-dimensional echocardiography is limited for assessment of postoperative myocardial function. Myocardial contrast echocardiography (MCE) and 2-dimensional speckle tracking imaging (2D-STI) possess good value in assessing myocardial perfusion and systolic function. We used MCE and 2D-STI to explore the changes of myocardial perfusion and systolic function after percutaneous coronary intervention (PCI) in patients with coronary heart disease, and to evaluate the clinical value of MCE and 2D-STI.
methodsTwenty patients with coronary heart disease undergoing PCI were selected. MCE was performed before and one day after PCI, and 2D-STI and conventional ultrasound were performed before and a month after PCI. The recovery of left ventricular wall motion was used as a standard to evaluate the ability of MCE semi-quantitative analysis and to predict the recovery of myocardial segment motion.
resultsThe quantitative value of MCE (signal intensity of contrast medium in plateau phase, slope of curve, and their product) one day after PCI and the contractile function of one month after PCI were significantly improved (all
conclusionsMCE and 2D-STI can evaluate the improvement of myocardial perfusion and systolic function in patients with coronary heart disease after PCI, and MCE semi-quantitative analysis can effectively predict the ability of ventricular wall recovery.
