A Cardiac Magnetic Resonance Study: Comparison of Biventricular Longitudinal Function in Hypertrophic Cardiomyopathy Patients and Normal Individuals.

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
objectiveHypertrophic cardiomyopathy (HCM) is a genetic disease with an incidence of 0.2%-0.5%. It has a wide range of clinical presentations varying from coincidental diagnoses to heart failure, ventricular arrhythmias and sudden cardiac death. Mitral annular plane systolic excursion (MAPSE) and tricuspid annular plane systolic excursion (TAPSE) are M-mode-derived practical and reproducible measurements of systolic longitudinal displacement of the annular plane. These two measures may be used as markers of the left ventricular and right ventricular longitudinal functions. Currently, there are only a few studies on cardiac magnetic resonance (CMR)-derived TAPSE and MAPSE measurement comparison between the HCM group and normal control group. The aim of our study is to show the differences in CMR-derived TAPSE and MAPSE values between the HCM and normal population.
methodsWe evaluated CMR exams of patients diagnosed with HCM and of normal individuals scanned between 2020 and 2021 retrospectively. The patients were from our own institution's and other hospitals' in- and out-patient departments. Data was collected on 36 HCM patients and 34 adults with no known history of cardiac and non-cardiac diseases. All CMR exams were performed on a 1.5 T (Magnetom Avanto, Siemens Healthcare, Erlangen, Germany) scanner. CMR-derived MAPSE and TAPSE were measured on standard four-chamber steady-state free precession (SSFP) cine images and given in millimeters.
resultsFrom February 2020 to December 2021, a total of 150 patients were diagnosed with hypertrophic cardiomyopathy. After exclusion, 36 patients with HCM were included in the study and the normal control group comprised 34 individuals. The mean age of the HCM group was 43.2 + 13.5 years, while it was 37.5 + 11.3 in the control group. The female ratio of the HCM group was found to be 36%, while it was 56% in the healthy control group. MAPSE values were significantly higher in the normal control group when compared to the HCM patient group (MAPSE: 14.5 ± 2.9 mm vs. 11.7 ± 3.2 mm; p<0.001), while TAPSE values did not depict a significant difference between the two groups (p=0.627).
conclusionsThis study suggests that MAPSE values are significantly lower in the HCM patient group in comparison with the normal control group on CMR scans. Although not statistically significant, TAPSE values are also lower in the HCM group.
