Abstract
Aging accelerates the degeneration and calcification of heart valves, driving valvular heart disease (VHD) development. As Japan's population ages, the prevalence of VHD continues to rise, increasing the burden on caregivers. This article draws on insights from the Japan Heart Health Survey (JHHS) and a targeted literature review to examine VHD's impact on caregivers who support older patients in Japan. The discussion also explores how promoting early diagnosis and treatment through medical innovations can help alleviate caregiver burden. Caregiving burden is multifaceted, impacting caregivers physically, emotionally, and financially. However, older patients often underestimate its impact. Underdiagnosis and undertreatment of VHD can exacerbate symptoms, contributing to greater caregiving strain. Low awareness among older adults and caregivers was identified as a key barrier to timely diagnosis and treatment of VHD. Leveraging advancements in medical innovation, including less invasive treatment options, could improve attitudes toward treatment, enhancing patient independence, and easing caregiving demands. Addressing the burden of VHD requires acknowledging its significant, often overlooked, impact on caregivers. Targeted public health initiatives can increase disease awareness and promote less invasive treatment options to encourage treatment. With more effective VHD management, both patients and caregivers can be adequately supported, ultimately improving health outcomes for all.
