About

Valvular heart diseases (VHD) are the most common causes of mortality and morbidity after coronary artery disease, hypertension, and heart failure, especially in senile patients who have more comorbidities and often require intervention. The prevalence of senile VHD is increased gradually as the growth of the age. In addition important changes have occurred as regards the presentation and treatment of the disease over recent years. However, there is little information about senile VHD in China. The purposes of this study are to evaluate the clinical characteristics, reasons for hospitalization, risk stratification, treatment modalities, quality of life and outcomes of senile hospitalized patients with VHD, to determine the risk factors affecting the prognosis, further to lay the foundation for establishing a prognosis model suitable for Chinese senile VHD.
