Clinical features and ageing-related changes in patients with venous thromboembolism / 中华老年医学杂志

ABSTRACT

Objective To investigate the clinical and epidemiological characteristics of pulmonary thromboembolism (PTE) and deep venous thrombosis (DVT). Methods The clinical data of 114 200 inpatients from June 2002 to June 2008, including gender, age, smoking history, primary disease and risk factors, were reviewed. Results There were 1445(1.27%) cases with venous thromboembolism (VTE), while 1433(1. 25%) patients suffered from DVT and 153(0. 13%) patients suffered from PTE, 16(11. 11 %) patients were dead of PTE. Of all the DVT patients, there were 1348(94. 1%) cases with DVT of lower limbs with no significant difference between left or right lower limb (P>0. 05). There were 49(3.4%) cases with inferior vena cava, 23(1.6%) cases with cavitas pelvis veins and 13(0. 9%) cases with upper extremity veins. The peak ages of morbidity were between 51 to 60 years. Conclusions The incidence of VTE is increasing with ageing and there is no significant difference between males and females. The most common risk factors for thromboembolism include trauma, surgery, cardiac and pulmonary disease, age over 50 years, deep phlebitis, long-term smoking, cancer, pregnancy, childbirth, braking, history of VTE, etc. We may lower the incidence and mortality of VTE by strengthening prevention work according to the high risk factors.
