Non-cardiac condition limiting life expectancy to \\\u003C1 year;\n  7. Presence of any of the following cardiac conditions:\n\n     * Other forms of cardiomyopathy contributing to heart failure (e.g., inflammatory or infiltrative cardiomyopathy)\n     * Clinically significant cardiac anatomic abnormalities (e.g., left ventricular aneurysm)\n     * Significant coronary artery disease (e.g., prior revascularization, exercise-induced angina)\n     * Uncorrected, hemodynamically significant (moderate to severe) primary structural valvular disease not due to heart failure (investigator's judgment)\n  8. Any severe concurrent disease (e.g., active systemic infection) that, in the investigator's judgment, would make the participant unsuitable for study participation;\n  9.

By establishing a cohort of patients with inherited cardiomyopathy, the study will collect comprehensive data, including demographic characteristics, disease history, clinical features, prior treatments, current treatment patterns, clinical outcomes, and patient-reported outcomes (PROs). The objective is to describe the disease profile, current diagnostic and therapeutic landscape, clinical progression, and prognosis of this specific patient population in China. The data generated will provide a foundational basis for deepening the understanding of disease progression, identifying unmet clinical needs, and exploring potential surrogate endpoints for future clinical trials in drug development. The study plans to enroll 10 eligible patients with BCL-2-associated athanogene 3 (BAG3)-associated inherited DCM from 3 research sites across China.",[54],"Dilated Cardiomyopathy",[56],"BAG3 ; Dilated cardiomyopathy; Observational Cohort Study","NOT_YET_RECRUITING","2026-06-09",{"date":60,"type":61},"2026-06-15","ACTUAL",{"date":63,"type":50},"2026-06-29",{"date":65,"type":50},"2029-06-29",{"name":5,"class":6},1]
