Investigation of short-term prognosis of fragmented QRS complexes in patients with acute myocardial infarction in two groups that received invasive and fibrinolytic therapy.

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
backgroundStudies have shown that the primary causes of death in patients with acute coronary syndrome are arrhythmias and heart failure. The aim of this study is to evaluate the short-term prognosis of fragmented QRS (f-QRS) in patients with acute myocardial infarction (MI).
methodsThis study was a prospective and longitudinal analytic study performed on all patients with acute MI admitted to Rasht Heshmat Hospital Emergency during 2018-2019. Serial Electrocardiography (ECG) was performed in the emergency room after patient admission and was repeated 24 h after percutaneous coronary intervention and fibrinolytic therapy, as well as at the time of patient discharge. Short-term prognosis of f-QRS in patients was evaluated by a cardiologist within admission, 40 days after hospitalization and three months later again.
resultsIn this study, 453 patients with MI were evaluated in two treatment methods of fibrinolytic and invasive with and without f-QRS. Based on the data of this study, the four study groups had no statistically significant difference in arrhythmia (p = 0.196). In addition, the effect of study groups on left ventricular ejection fraction index was not statistically significant (p = 0.597). The probability of adverse outcomes occurrence was not statistically significant among the four groups (p = 0.07).
conclusionThe final results of this study showed that there was no significant difference between the four study groups and arrhythmia status. Therefore, f-QRS was not introduced as an independent predictor of arrhythmia in patients with acute MI.
