Clinical features, imaging characteristics, and genetic profile of hypertrophic cardiomyopathy patients in India.
Article in Indian heart journal. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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) is an autosomal dominant genetic disorder characterized by left ventricular hypertrophy and variable clinical manifestations, including asymptomatic states and sudden cardiac death (SCD). Data on its phenotype and genotype in the Indian population remain limited.
methodsWe studied 113 patients diagnosed with HCM. All underwent clinical assessment, 24-h Holter monitoring, echocardiography, and cardiac MRI. Genetic testing was performed in 80 patients. Clinical and imaging features were compared between genotype-positive and genotype-negative groups.
resultsThe mean age was 47 ± 10.8 years, with 82.6 % being males. Dyspnoea and chest pain were the most frequent symptoms. Obstructive HCM was seen in 70 (61.9 %) patients. Cardiac MRI showed late gadolinium enhancement >15 % in 13 (23.2 %) and apical aneurysms in 2 (3.5 %). Genetic mutations were detected in 40 (50 %) patients, with MYBPC3 (33 %) and MYH7 (26.8 %) being most common. Genotype-positive individuals more frequently had chest pain, a family history of SCD, and more severe hypertrophy.
conclusionIn this Indian HCM cohort, the condition predominantly affected males. Genotype-positive patients exhibited more severe hypertrophy and adverse clinical profiles, underscoring the importance of genetic screening in risk stratification.
