This prospective observational investigation will examine the incidence and progression of cardiologic findings in individuals with OI across different age groups. Cardiopulmonary complications are recognized as major contributors to morbidity and mortality in adults with OI, although life expectancy has significantly improved in recent years due to medical advancements. By systematically evaluating cardiovascular involvement in this population, the study aims to generate clinically relevant evidence to inform early cardiologic screening strategies and support the development of harmonized and targeted management approaches, ultimately improving clinical practice and the quality of life of individuals living with OI.
