Clinical and Echocardiographic Particularities of Hypertrophic Cardiomyopathy in a Brazilian Population and its Prognostic Impact.

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
backgroundHypertrophic cardiomyopathy (HCM) presents echocardiographic abnormalities that are important for diagnosis and prognosis. Data are scarce in the Brazilian literature.
objectiveTo assess clinical and echocardiographic characteristics and disease progression in a Brazilian cohort of patients with HCM.
methodsThis retrospective cohort included patients with HCM aged ≥ 18 years. Patients with moderate or severe aortic stenosis and those undergoing septal reduction were excluded. The significance level adopted in the statistical analysis was 5%.
resultsThe study included 1244 patients, between 2010 and 2022, with a mean follow-up time of 7.7 ± 4.5 years; 53.6% of patients were men. Mean age was 54.6 ± 16.5 years, and mean left ventricular ejection fraction (LVEF) was 65.8% ± 7.6. We observed LVEF ≤ 50% in 5.8% of patients, asymmetric form in 88.7%, and septal hypertrophy in 85.4%. We found systolic anterior motion of the mitral valve in 30.1% of patients, left ventricular outflow tract obstruction in 30.7%, and septum ≥ 28 mm in 7.2%. Only 1 patient had ventricular aneurysm. Atrial fibrillation/flutter occurred in 9.6% of patients. Overall mortality occurred in 232 patients (1.3%/year). Patients with B-type natriuretic peptide (BNP) > 200 pg/ml, left atrium ≥ 45 mm, and LVEF ≤ 50% had higher mortality (p < 0.001). Age and atrial fibrillation/flutter were also associated with mortality.
conclusionsThe majority of patients had LVEF > 50%, asymmetric hypertrophy, and septal predominance. BNP, LA diameter, LVEF ≤ 50%, age, and atrial fibrillation/flutter were associated with worse prognosis.
