Brief summary

This study aims to conduct a second round of multicenter, prospective registry research targeting elderly patients with valvular heart disease, to understand the current status of interventions for patients with valvular heart disease. To systematically evaluate the distribution of types, clinical characteristics, interventions, and complications of elderly valvular heart disease, and to compare and analyze these with the China-DVD data from 2016, thereby revealing its evolutionary trends. By comprehensively considering various clinical characteristics such as different types of valvular lesions, treatment modalities, patient cardiac function, comorbidities, and blood test indicators, as well as multidimensional factors including psychological and lifestyle aspects, to deeply identify the key determinants influencing the treatment of elderly valvular heart disease patients in China, and thus optimize and improve their individualized comprehensive management pathways.

Design outcomes

Primary

MeasureTime frameDescription
First valve intervention during this hospitalizationFrom enrollment to the end of treatment at 12 weeksUnderwent their first internal medicine intervention or surgical procedure during hospitalization for valvular heart disease in this study

Secondary

MeasureTime frameDescription
1、Repeat valve intervention 2、Cardiovascular adverse eventsFrom enrollment to the 12-month follow-up endpoint1 、Repeat valve intervention : After the first valve intervention, the patient receives another valve surgical or interventional procedure due to valvular-related causes. 2、Cardiovascular adverse events : Any new-onset or recurrent cardiovascular disease, rehospitalization for cardiovascular reasons, and cardiac death, etc.
