ABSTRACT
Objective@# To investigate the incidence and trends in incidence of stroke among residents in Lianyungang City, Jiangsu Province from 2014 to 2020, so as to provide insights into stroke control. @*Methods@#The stroke morbidity data in Lianyungang City from 2014 to 2020 were captured from Lianyungang Municipal System for Monitoring of Cardiovascular and Cerebrovascular Diseases, and standardized by the sixth national population census data in China in 2010. The trends in stroke incidence were evaluated using average annual percentage change (AAPC), and the gender-, age-, region- and disease type-specific incidence and trends in incidence of stroke were descriptively analyzed. @*Results@#Totally 162 423 new stroke cases were diagnosed in Lianyungang City from 2014 to 2020 new case, and the annual mean crude and standardized incidence rates were 435.32/105 and 357.28/105, which both appeared a tendency towards a rise (AAPC=12.61%, t=39.098, P<0.001; AAPC=9.91%, t=6.123, P<0.001) . The standardized incidence of stroke was significantly higher in men than in women (389.63/105 vs. 327.17/105; χ2=4.056, P=0.044). The crude incidence of stroke appeared a tendency towards a rise with age among residents (χ2trend=258.219, P<0.001), and appeared a tendency towards a rise among residents at ages of <35 (AAPC=22.52%, t=6.723, P<0.001), 35 to 64 (AAPC=9.78%, t=7.867, P<0.001) and 65 years and older (AAPC=10.24%, t=5.156, P<0.001). The crude incidence was higher in rural areas than in urban areas (437.72/105 vs. 425.31/105; χ2=20.709, P<0.001). Ischemic stroke was the predominant type (139 680 cases, 86.00% of all cases), and both the crude and standardized incidence appeared a tendency towards a rise (AAPC=13.79%, t=16.865, P<0.001; AAPC=10.88%, t=5.128, P<0.001). @*Conclusion@# The incidence of stroke appeared a tendency towards a rise among residents living in Lianyungang City from 2014 to 2020. Men, middle-age and elderly residents and rural residents are high-risk populations for stroke control.
ABSTRACT
Objective To compare intravascular ultrasound (IVUS) and coronary angiography in measuring the lumen diameter and coronary arteries stenosis rate, to investigate the impact of IVUS in the choice of surgical indications, surgical procedure guidance and effects of operation.Methods The patients who underwent percutaneous coronary intervention(PCI) therapy from may 2013 to may 2014 were divided into IVUS-guided intervention therapy group (n=89) and coronary angiographyguided group (n=90).Their baseline parameters, lesion features, MACE and restenosis during follow-up were analyzed.Results Baseline clinical and angiographic characterisitcs were well matched and show no significant differences between the two groups.Compared to angiography-guided group, the minimum lumen diameter (MLD) of IVUS-guided group were higher, diameter stenosis (DS) and lesion length (LL) were lower in IVUS-guided intervention therapy group.The detection rate of calcified and eccentric lesion were significantly higher in IVUS-guided group.There were 204 (93.6 ％) and 195 (87.8％) high-pressure balloons used in post-inflation in two groups, respectively.The MLD and plaque burden of IVUS-guided group were obviously improved after stent implantation.Conclusions IVUS-guided intervention therapy in PCI is safe and effective, may be helpful for the judgment of lesion, evaluating stent implantation and guiding high-pressure balloon post-inflation.IVUS-guided intervention could get the bigger immediate lumen diameter and lower plaque burden than coronary angiography without serious short-term or long-term complications.
