RESUMEN
Objective To evaluate quantitative coronary angiography (QCA) measurement of culprit vessel fixed stenosis in acute ST segment elevation myocardial infarction (STEMI) emergency interventional thrombus aspiration.Methods One hundred and sixty-fore cases of STEMI patients accepting emergency interventional operation and thrombus aspiration treatment were choosed from September 2012 to October 2013 in the First Affiliated Hospital of Wenzhou Medical University.Thrombus Aspiration measuring vessel was carried after criminals using fixed stenosis rate QCA methods.Results The vascular stenosis rate was more than 50％ in 69.5％ of the male patients,vascular stenosis rate was more than 70％ in 40.2％ of the female patients,the anterior descending branch of the rami anterior descendens(LAD) (54.75％ ± 29.72％,n=76),Left circumflex artery (LCX) (55.25％ ± 32.23％,n =20),arteriae coronaria dextra (RCA) (56.40％ ± 29.76％,n =68).There was no difference between LAD,LCX and RCA (F=6.036,0.955,0.055;P＞0.05).Conclusion The most majority of serious vascular stenosis patients have acute STEMI.
RESUMEN
ObjectiveTo investigate the changes and values of serum high-sensitivity C-reactive protein (hs-CRP) and cardiac troponin I (cTnI) in patients with chronic heart failure.MethodsEighty patients with chronic heart failure (heart failure group) were divided into NYHA heart function Ⅲ grade ( 40 patients) and Ⅳ grade (40 patients).Eighty healthy people were included in control group.The levels of serum hs-CRP and cTnI were measured and compared.ResultsBefore treatment,the levels of hs-CRP and cTnI in heart failure group [ ( 11.56 ± 2.72) mg/L,(0.46 ± 0.11 ) μ g/L] were significantly higher than those in control group [ (2.31 ± 0.56) mg/L,(0.04 ± 0.13 ) μg/L ] (P ＜ 0.01 ).The levels of hs-CRP and cTnI in heart function Ⅳ grade patients [ ( 13.07 ± 4.31 ) mg/L,(0.57 ± 0.05 ) μg/L] were significantly higher than those in heart function Ⅲ grade patients [(10.04 ±3.12) mg/L,(0.35 ±0.09) μg/L](P＜0.01).After treatment,the levels of hs-CRP and cTnI in heart function Ⅲ grade and Ⅳ grade patients were significantly decreased compared with those before treatment(P＜ 0.01 ).ConclusionsThe levels of hs-CRP and cTnI in chronic heart failure patients are related to the inflammatory activities and myocardial damage.hs-CRP and cTnI may be effective factors to reflect the severity of heart failure.
