Microvascular Dysfunction in COVID-19 Patients with Acute 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
Objective: Coronavirus disease 2019 (COVID-19) is considered to deteriorate endothelial function through hyperinflammation. We aimed to investigate microvascular dysfunction using the angiographic parameters thrombolysis in myocardial infarction frame count (TFC) and myocardial blush grade (MBG), in COVID-19 patients with acute coronary syndrome (ACS). Methods: One hundred and sixty-five patients presented with ACS (62.4% ST elevated myocardial infarction) and underwent percutaneous coronary intervention between March 1 and June 30, 2020, were enrolled in the study. The polymerase chain reaction test was performed in case of suggestive symptoms or typical computerized tomography findings. Results: Twenty-six patients (15.7%) were tested positive for COVID-19. Significantly higher values were observed in TFC in patients with COVID-19 (p<0.001), whereas COVID-19 patients had significantly lower MBGs (Grade 0 and 1) (p<0.001). Peak troponin-I value was also higher in the COVID-19 group (27335 vs. 15959 ng/dL, p=0.006). Mortality risk was higher in COVID-19 patients (38.4% vs. 7.2%, p<0.001). TFC and ejection fraction may predict in-hospital mortality among COVID-19 patients with ACS according to logistic regression results. In correlation analysis, TFC correlated positively with C-reactive protein (r=0.340, p<0.001) and peak troponin-I value (r=0.369, p<0.001). Conclusion: COVID-19 is associated with slow coronary flow and microvascular impairment in ACS.
