Comparison on clinical features between dilated cardiomyopathy patients with or without pulmonary hypertension / 中华心血管病杂志

<p><b>OBJECTIVE</b>The clinical data of dilated cardiomyopathy (DCM) patients with or without pulmonary hypertension (PH) diagnosed by echocardiography were compared.</p><p><b>METHODS</b>During January 2007 to December 2009, 61 cases of DCM with PH and 51 cases of DCM without PH were admitted in our department. The demographic and clinical data, heart function, echocardiography and serum total bilirubin and creatinine levels of all patients were analyzed.</p><p><b>RESULTS</b>Sex, age, vital signs, combined diseases and arrhythmias as well as the serum creatinine level [(103.5 ± 49.7) µmol/L vs. (90.3 ± 37.3) µmol/L, P > 0.05] were similar between the two groups, while the incidence of NYHA III and IV (95% vs. 65%), the left ventricle end-systolic dimension[(71.0 ± 9.6) mm vs. (65.5 ± 7.2) mm], dimension of the left atrium [(52.8 ± 8.93) mm vs. (43.9 ± 6.3) mm], right ventricular outflow tract [(29.1 ± 5.3) mm vs. (22.1 ± 3.3) mm] incidence of pericardial effusion (29/61 vs. 7/51) and the serum total bilirubin level [(45.3 ± 31.8) µmol/L vs. (19.5 ± 9.08) µmol/L] were significantly higher while ejective fraction was significantly lower in DCM with PH than those in DCM without PH (0.28 ± 0.10 vs. 0.36 ± 0.10, all P < 0.05).</p><p><b>CONCLUSION</b>DCM patients with PH is linked with worse clinical features than DCM patients without PH.</p>

Risk factors of pulmonary embolism among 303 patients in the First Clinical Hospital of Jilin University / 中华流行病学杂志

Objective To study the trend and changes regarding risk factors of pulmonary embolism among inpatients in the last 10 years from the First Clinical Hospital of Jilin University.Methods 303 cases of pulmonary embolism inpatients in our hospital from 2001-2010 were included and analyzed on related incidence,mortality and risk factors.Results Data showed that:(1)the incidence of pulmonary embolism increased from 0.09‰ to 1.12‰ while the mortality dropped from 73.3％ to 12.0％ ;(2)major risk factors would include thrombosis of deep veins,surgical operations,heart diseases,varicosity or phlebitis of lower extremities,trauma and fracture etc.,according to the order of incidence rates.Surgical operations had become the second major risk factor in the last 10 years.Conclusion The incidence of pulmonary embolism in our hospital showed a gradual drop while the mortality had a remarkable drop.Surgical operations had become one of the major risk factors of pulmonary embolism.
