Effect of cardiac shock wave therapy on the microvolt T wave alternans of patients with coronary artery disease.
Article in International journal of clinical and experimental medicine, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 2 of them syntheses that pooled it.
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
objectiveThe aim of this study was to evaluate the effect of cardiac shock wave therapy (CSWT) on microvolt T wave alternans (MTWA) in patients with coronary artery disease (CAD).
methods87 patients with old myocardial infarction (OMI) were enrolled in this study. Sixty-two patients were randomized into the CSWT group, 32 patients into the regular treatment group (Group A) according to different shock wave procedure, and 30 into the expanding scope treatment group (Group B), and 25 patients were randomized into the control group (Group C). But the shock wave (SW) energy was only applied to the patients in the CSWT group and not to the patients in the control group. Three months was a treatment course, thus patients received a total of 9 CSWT treatment sessions.
resultsTechnetium-99m sestamibi myocardial perfusion, fluorine-18 fluorodeoxyglucose myocardial metabolism single-photon emission computed tomography (SPECT) were performed to identify segments of myocardial ischemia, myocardial viability, and microvolt T wave alternans (MTWA) before and after CSWT. After CSWT, the rehospitalization rates of CSWT group were lower than control group (P<0.05). The myocardial ischemic segments, metabolism abnormal segments, total radioactive score of perfusion imaging and metabolism imaging, MTWA, and MTWA/HR in CSWT group were reduced significantly (P<0.05). And the heart rate of maximum MTWA, exercise time were increased significantly (P<0.05). All of the parameters in the control group did not change significantly even worsen after the treatment (P>0.05).
conclusionsCSWT can reduce the MTWA value, improve the heart chronotropic function and increase the threshold of frequency which causes MTWA.
