Association between mitral annulus calcification and severity of coronary artery disease assessed by SYNTAX score in patients presented 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
Objectives: Mitral annulus calcification (MAC) has been linked to cardiovascular disease severity, but its relationship with the SYNTAX score (SS) in acute coronary syndrome (ACS) patients remains unclear. This study aimed to investigate the association between MAC and SS in ACS patients to explore the role of MAC in predicting cardiovascular disease severity. Methods: We conducted a cross-sectional study of 233 ACS patients at Tehran Heart Center, Tehran, Iran, from December 2021 to August 2022. Patients with prior coronary artery disease (CAD) were excluded. Demographic data, risk factors, and medical history were extracted from clinical files. SS was determined using coronary angiography, and MAC was assessed via two-dimensional transthoracic echocardiography. Results: The study population had a mean age of 58.79 years, with 74.7% male. MAC was present in 24.9% of participants, and 57% of those with MAC had an SS above 23. Univariate analysis revealed a significant association between MAC and higher SSs (odds ratio: 1.84, 95% CI: 1.02-3.39; Conclusion: While MAC was initially associated with higher SSs in ACS patients, only LVEF emerged as an independent predictor in the multivariable analysis. Although MAC may not be independently associated with SS, it may serve as a useful echocardiographic indicator of more severe CAD in ACS.
