Abstract
Noninvasive cardiac imaging plays a critical role in the diagnosis and risk stratification of cardiovascular disease in older adults, a population marked by clinical heterogeneity, multimorbidity, and age-related physiologic changes. This review outlines the strengths and limitations of commonly used imaging modalities including echocardiography, transesophageal echocardiography, cardiac computed tomography, nuclear imaging tests, and cardiac magnetic resonance imaging in the context of aging. We highlight diagnostic challenges such as limited exercise capacity, image quality artifacts, reduced specificity in the setting of multivessel, or microvascular disease and intolerance to longer scan protocols. Advances in imaging technology, including artificial intelligence and hybrid protocols, offer opportunities to improve accuracy, access, and individualized decision-making. The review emphasizes the importance of tailoring test selection to patient comorbidities and goals of care. Addressing current evidence gaps through trials inclusive of older adults and geriatric-focused imaging guidelines is essential to delivering equitable, high-value cardiovascular care to older adults.
