The COngenital HeARt Disease in adult and Pulmonary Hypertension (COHARD-PH) registry: a descriptive study from single-center hospital registry of adult congenital heart disease and pulmonary hypertension in Indonesia

Abstract Backgrounds: The COngenital HeARt Disease in adult and Pulmonary Hypertension (COHARD-PH) registry is the first registry for congenital heart disease (CHD) andCHD-related pulmonary hypertension (PH) in adults in Indonesia.The study aims to describethe demographics, clinical presentation, and hemodynamics data of adult CHD and CHD-related PH in Indonesia. Methods: The COHARD-PH registry is a hospital-based, single-center, and prospective registry which includes adult patients with CHD and CHD-related PH. The patients were enrolled consecutively. For this study, we evaluatedthe registry patients from July 2012 until July 2019. The enrolled patients underwent clinical examination, electrocardiography, chest x-ray, 6-minute walking test, laboratory measurement, and transthoracic and transesophageal echocardiography. Right heart catheterization was performed to measure hemodynamics and confirmthe diagnosis of pulmonary artery hypertension (PAH). Results: We registered 1012 patients during the study.The majority were young, adult females.The majority of CHD was secundum ASD (73.4%). The main symptom was dyspnea on effort. The majority of patients (77.1%)had already developed signs of PH assessed by echocardiography. The Eisenmenger syndrome was encountered in 18.7% of the patients. Based on the right heart catheterization, 66.9% of patients had developed PAH. Patients with PAH were significantly older,had lower peripheral oxygen saturation, had lower 6-minute walking distance, and higher NTproBNP. The NTproBNP level independently predicted the development of PAH among CHD. Conclusions: The COHARD-PH registry is the first Indonesian adult-CHD and CHD-related PH registry. The demographics, clinical presentation, and hemodynamics dataof this registry reflect the situation in developing countries which needs to be compared with similar registries from developed countries.
