文摘Atrial fibrillation(AF)and prediabetes share common pathophysiological mechanisms with endothelial dysfunction and inflammation playing a key role.The resultant vicious cycle which sets in culminates in a higher atherogenicity and thermogenicity of the vascular system resulting in increased major adverse cardiac or cerebrovascular event(MACCE)events.However,the same has not convincingly been verified in real-world settings.In the recent retrospective study by Desai et al amongst AF patients being admitted to hospitals following MACCE,prediabetes emerged as an independent risk factor for MACCE after adjusting for all confounding variables.However,certain questions like the role of metformin,quantifying the risk for MACCE amongst prediabetes compared to diabetes,the positive impact of reversion to normoglycemia remain unanswered.We provide our insights and give future directions for dedicated research in this area to clarify the exact relationship between the two.
文摘BACKGROUND Non-alcoholic fatty liver disease(NAFLD)increases the risk of cardiovascular diseases independently of other risk factors.However,data on its effect on cardiovascular outcomes in coronavirus disease 2019(COVID-19)hospitalizations with varied obesity levels is scarce.Clinical management and patient care depend on understanding COVID-19 admission results in NAFLD patients with varying obesity levels.AIM To study the in-hospital outcomes in COVID-19 patients with NAFLD by severity of obesity.METHODS COVID-19 hospitalizations with NAFLD were identified using International Classification of Disease-10 CM codes in the 2020 National Inpatient Sample database.Overweight and Obesity Classes Ⅰ,Ⅱ,and Ⅲ(body mass index 30-40)were compared.Major adverse cardiac and cerebrovascular events(MACCE)(all-cause mortality,acute myocardial infarction,cardiac arrest,and stroke)were compared between groups.Multivariable regression analyses adjusted for sociodemographic,hospitalization features,and comorbidities.RESULTS Our analysis comprised 13260 hospitalizations,7.3% of which were overweight,24.3% Class Ⅰ,24.1% Class Ⅱ,and 44.3% Class Ⅲ.Class Ⅲ obesity includes younger patients,blacks,females,diabetics,and hypertensive patients.On multivariable logistic analysis,Class Ⅲ obese patients had higher risks of MACCE,inpatient mortality,and respiratory failure than Class Ⅰ obese patients.Class Ⅱ obesity showed increased risks of MACCE,inpatient mortality,and respiratory failure than Class I,but not significantly.All obesity classes had non-significant risks of MACCE,inpatient mortality,and respiratory failure compared to the overweight group.CONCLUSION Class Ⅲ obese NAFLD COVID-19 patients had a greater risk of adverse outcomes than class Ⅰ.Using the overweight group as the reference,unfavorable outcomes were not significantly different.Morbid obesity had a greater risk of MACCE regardless of the referent group(overweight or Class Ⅰ obese)compared to overweight NAFLD patients admitted with COVID-19.
文摘目的探讨脑小血管(cerebral small vessel disease,CSVD)负担评分对短暂性脑缺血发作(transient ischemic attack,TIA)患者复发性脑血管事件(recurrence cerebrovascular events,RCVEs)的预测价值。材料与方法回顾性分析2019年10月至2022年12月期间于安徽省第二人民医院就诊的182例TIA患者病例资料,依据MRI检查计算CSVD总体负担评分,根据随访1个月内有无发生RCVEs分为RCVEs组(n=46)和未RCVEs组(n=136)。比较两组临床资料和CSVD总体负担评分,采用多因素logistic回归分析模型分析RCVEs的独立危险因素,绘制受试者工作特征(receiver operating characteristic,ROC)曲线分析CSVD影像特征得分及总负担评分对TIA患者RCVEs的预测价值。结果RCVEs组和未RCVEs组TIA发作次数、症状持续时间、既往高血压病史、CSVD总负担评分及分级情况比较差异有统计学意义(P<0.05)。多因素logistic回归分析结果显示:TIA发作次数、症状持续时间、CSVD总负担评分是TIA患者发生RCVEs的独立危险因素(P<0.05)。ROC曲线分析结果显示:CSVD影像特征评分及总负担评分预测TIA患者发生RCVEs的曲线下面积(areas under the curve,AUC)分别为0.771(95%CI:0.673~0.869,P<0.001)、0.745(95%CI:0.655~0.835,P<0.001)、0.664(95%CI:0.549~0.780,P=0.009)、0.845(95%CI:0.766~0.924,P<0.001)、0.945(95%CI:0.896~0.994,P<0.001),其中CVSD总负担评分预测的AUC最高,当最佳截断值为2分时,敏感度为86.05%,特异度为83.02%。结论CSVD总负担评分对TIA患者发生RCVEs的预测价值良好,有助于临床评估TIA患者的短期预后。
