Frailty of Elderly With Valvular Heart Disease and the Short Term Adverse Events

Elderly, Frailty, Valvular Heart Disease

Despite the rapid development of medical and nursing technology, the prognosis of valvular heart disease has been greatly improved. However, compared with young patients, the mortality and adverse event rate of elderly patients with valvular heart disease are still high, surgical complications are more frequent and hospitalization time is longer. The complexity of valvular heart disease and the poor prognosis in the elderly forces us to continue to look for other potential prognostic factors. In addition to the adverse outcomes caused by disease factors, elderly patients with valvular heart disease also have the gradual decline of physiological and psychological reserve function caused by age factors. These adverse outcomes include osteopenia, disability, prolonged hospitalization and even death are all closely related to frailty. Frailty is 'a biologic syndrome of decreased reserve and resistance to stressors, resulting from cumulative declines across multiple physiologic systems, and causing vulnerability to adverse outcomes. The essence of frailty is the decline of individual resistance, which eventually leads to the increase of individual brittleness and susceptibility to adverse health outcomes. At present, the research in the field of elderly vulnerable groups of cardiovascular disease in China started late, mostly focusing on the study of pathological mechanism, the introduction of evaluation tools, conceptual analysis and so on. Almost all of the existing studies are about the debilitation status of elderly patients with heart valve disease, and most of them mainly try to find the influencing factors of debilitation from the aspects of patients' physical diseases, ignoring the impact of factors such as the mental health status of the elderly on debilitation, there are few reports of short-term adverse events in elderly patients with valvular heart disease. This study will analyze the influencing factors of the weakness of elderly patients with valvular diseases from the multi-dimensional aspects of demographic data, physical diseases, psychology and society, and track the short-term prognosis of patients with death, fall and unconventional rehospitalization, so as to provide a research basis for relevant research in the future.
