ABSTRACT
Objective:To compare the application value of Caprini thrombosis risk assessment scale and Shanghai venous thrombosis risk factor scale in predicting venous thromboembolism in hospitalized maternal patients.Methods:This was a case-control study. A total of 67 pregnant women complicated with venous thromboembolism in the Obstetrics Department of Shandong Provincial Hospital Affiliated to Shandong First Medical University from January 2010 to September 2021 were retrospectively analyzed. And 144 pregnant women without venous thromboembolism in the same period were selected. Two venous thrombosis risk assessment tools were used to evaluate the pregnant women, and the predictive effectiveness and accuracy of the two assessment tools were compared.Results:The effects of the two risk assessment tools for venous thrombosis were different before and after delivery with statistical difference ( Z=8.15, 5.97, both P<0.01), but the Shanghai venous thrombosis risk factor scale (83.9%, 67.3%) was superior to Caprini thrombosis risk assessment scale (52.1%, 45.0%) in the accuracy of prenatal and postnatal prediction. The area under receiver operating characteristic curve showed that the Shanghai venous thrombosis risk factor rating scale (0.863) was significantly superior to the Caprini thrombosis risk assessment scale (0.748) after delivery. Conclusions:The Shanghai venous thrombosis risk factor scale is more valuable than the Caprini thrombosis risk assessment scale in the early risk identification of venous thromboembolism in pregnant women.
ABSTRACT
Objective Through clinical observation and research with persistent atrial fibrillation in patients with blood-brain natriuretic peptide ( BNP) level change detection renin, angiotensin Ⅱ, aldosterone, analyze their data, investigate persistent atrial fibrillation ( PAF ) serum brain natriuretic hormone levels change and the relationship between the renin-angiotensin-aldosterone system (RAAS).Methods 80 patients with coronary artery disease in our hospital from December 2013 to October 2015 were selected, randomly divided into experimental principle PAF group (40 cases) and control group ( patients in sinus rhythm,with 40 cases) , BNP, renin, angiotensinⅡ, aldosterone levels were measured in two groups, and left atrial diameter (LAD) measurements.Results Under the same condition of cardiac function, the blood BNP concentration in PAF group was higher than that in control group (P <0.05).The results of the linear regression analysis showed that the correlation coefficient of blood BNP level and AngII concentration in PAF group was 0.301, the correlation coefficient of blood BNP level and LAD indicators in PAF group was 0.373, the concentrations of BNP and RAAS were positively correlated with LVMI, the differences were statistically significant (P<0.05), the blood BNP level was closely related to the level of RAAS in the PAF group (P<0.05).Conclusion Blood BNP concentration was significantly higher in patients with PAF and blood BNP concentration is closely related with the RAAS, LAD indicators, and a positive correlation.
