Objective To examine the association of atherosclerotic cardiovascular disease(ASCVD)and its risk factors with cognitive impairment in older adults.Methods Six hundred and fourteen subjects,aged≥65 years,from one center(2016–2018)underwent clinical,laboratory assessments and the Montreal Cognitive Assessment(Mo CA).Using regression analysis,the relationship between ASCVD and its risk factors was evaluated in subjects with and without cognitive impairment(MoCA score<26).Results Older age(b=-1.3 per 5 years,95%CI:-1.7 to-0.9,P<0.001),history of stroke(b=-1.6,95%CI:-3.0 to-0.3,P=0.01),and myocardial infarction(MI;b=-2.2,95%CI:-3.6 to-0.8,P=0.003)were independently associated with lower MoCA scores,whereas more education(b=1.5 per 3 years,95%CI:1.1 to 1.9,P<0.001),higher body mass index(BMI;b=0.5 per 3 kg/m^2,95%CI:0.0 to 1.0,P=0.04),higher estimated glomerular filtration rate(eGFR;b=0.8 per 15 U,95%CI:0.1 to 1.4,P=0.03),left ventricular ejection fraction(LVEF;b=0.4 per 5%,95%CI:0 to 0.8,P=0.04)and statin use(b=1.3,95%CI:0.3 to 2.3,P=0.01)were associated with a higher MoCA score.Cognitive impairment was independently associated with older age(OR=1.51 per 5 yrs,95%CI:1.28 to 1.79,P<0.001),less education(OR=0.55 per 3 years,95%CI:0.45 to 0.68,P<0.001),lower BMI(OR=0.78 per 3 kg/m^2,95%CI:0.62 to 0.98,P=0.03)and higher levels of high sensitivity c-reactive protein(hsCRP;OR=1.08 per 1 mg/L,95%CI:1.02 to 1.15,P=0.01).Conclusions Beyond age,cognitive impairment was associated with prior MI/stroke,higher hsCRP,statin use,less education,lower eGFR,BMI and LVEF. 展开更多

Objective To examine the association of atherosclerosis burden in the survivors of an asymptomatic elderly cohort study and its relationship to other coronary risk factors (specifically, age) by evaluating aortic atherosclerotic wall burden by magnetic resonance imaging (MRI). Methods A total of 312 participants in an ongoing observational cohort study underwent cardiac and descending thoracic aorta imaging by MRI. Maximum wall thickness was measured and the mean wall thickness calculated.Wall/outer wall ratio was used as a normalized wall index (NWI) adjusted for artery size difference among participants. Percent wall volume (PWV) was calculated as NWI ×100.Results In this asymptomatic cohort (mean age: 76 years), the mean (SD) aortic wall area andwall thicknesswere 222 ±45 mm2 and 2.7 ±0.4 mm, respectively. Maximum wall thickness was 3.4 ±0.6 mm, and PWV was 32% ±4%. Women appeared to have smaller wall area,but after correcting for their smaller artery size, had significantly higher PWV than men (P = 0.03). Older age was associatedwith larger wall area (P = 0.04 for trend) with similar PWVs. However, there were no statistically significant associations between standard risk factors,Framingham global risk, or metabolic syndrome status, therapy for cholesterol or hypertension, coronary or aortic calcium score, and the aortic wall burden. Aortic calcificationwas associated with coronary calcification. Conclusions Asymptomatic elderly in this cohort had a greater descending thoracic aortic wall volume that correlated with age, andwomen had a significantly increased PWV compared to men. In these survivors, the atherosclerotic aortic wall burden was not significantly associated with traditional risk factors or with coronary or aortic calcium scores or coronary calcium progression. Results suggest that age, or as yet unidentified risk factor(s), may be responsible for the increase in atherosclerosis. 展开更多
