Preliminary Investigation Of The Epidemiology Of COPD Inpatients With Deep Venous Thrombosis

Objective: COPD patients have the high risk of deep venousthrombosis(DVT) due to their disease characteristics. In this study,we researched the initial cross-section of inpatients’ lower extremitydeep venous thrombosis and explored the incidence and riskfactors for DVT among COPD inpatients.Methods: We enrolled111COPD inpatients who werehospitalized in the third ward of respiration department fromFebruary2011to December2011, and we collected somedemographic data including patients’ age, gender, height, weight,history of alcohol&cigarette and medical disease, et al.Furthermore, pulmonary function tests were employed to thesepatients during their hospitalization, and their lower limbs werechecked by the entire venous color Doppler ultrasound within48-96hours after they were admitted. After these medical examination,we recorded their clinical data such as the pulmonary function testresults, the images of color Doppler ultrasound examination of thewhole vein of lower limbs, four coagulation tests, D-dimervalues, serum total protein values, and serum albuminvalues, et al. According to the facts, these patients were divided into two groups: the deep venous thrombosis group (DVT group)and the negative group (non-DVT group), and the data differencebetween these two groups were compared by chi-square test and ttest.Results: Among the111patients, we found12hadDVT(morbidity rate10.8%) in whom3were mixed thrombus,7were distal DVT, and2were proximal DVT.Compared with male patients’ thrombus-positive rate of7.29%,female patients had a33.33%positive rate, which means thedifference in DVT prevalence rates between genders wasstatistically significant. Based on the data, the D-dimer valuesdifference between DVT patients and non-DVT patients werestatistically significant, too. However, the results showed that age,BMI, smoking and drinking history, previous underlying disease,four coagulation tests, blood total protein, and blood albumin didnot be found a statistical difference between DVT patients andnon-DVT patientsConclusion In this study, the overall prevalence of DVTamong COPD inpatients was10.8%, male7.29%and female33.33%. The results indicated that gender factors greatly affectedDVT forming among COPD inpatients, and D-dimer values wererelated.
