Background: Whether drug therapy slows the growth of abdominal aortic aneurysms (AAAs) in the Japanese population remains unknown.Methods and Results: In a multicenter prospective open-label study, patients with AAA at the presurgical stage (mean [±SD] AAA diameter 3.27±0.58 cm) were randomly assigned to treatment with candesartan (CAN; n=67) or amlodipine (AML; n=64) considering confounding factors (statin use, smoking, age, sex, renal function), with effects of blood pressure control minimized setting a target control level. The primary endpoint was percentage change in AAA diameter over 24 months. Secondary endpoints were changes in circulating biomarkers (high-sensitivity C-reactive protein [hs-CRP], malondialdehyde–low-density lipoprotein, tissue-specific inhibitor of metalloproteinase-1, matrix metalloproteinase [MMP] 2, MMP9, transforming growth factor-β1, plasma renin activity [PRA], angiotensin II, aldosterone). At 24 months, percentage changes in AAA diameter were comparable between the CAN and AML groups (8.4% [95% CI 6.23–10.59%] and 6.5% [95% CI 3.65–9.43%], respectively; P=0.23]. In subanalyses, AML attenuated AAA growth in patients with comorbid chronic kidney disease (CKD; P=0.04) or systolic blood pressure (SBP) <130 mmHg (P=0.003). AML exhibited a definite trend for slowing AAA growth exclusively in never-smokers (P=0.06). Among circulating surrogate candidates for AAA growth, PRA (P=0.02) and hs-CRP (P=0.001) were lower in the AML group.Conclusions: AML may prevent AAA growth in patients with CKD or lower SBP, associated with a decline in PRA and circulating hs-CRP.

Background:Most patients with critical limb ischemia (CLI) exhibit severe comorbidities accompanied by frailty. This study assessed and risk-stratified mortality after infrainguinal bypass (IB) in CLI and investigated the effects of frailty.Methods and Results:The study retrospectively reviewed 107 consecutive CLI patients who had undergone de novo IB due to atherosclerotic disease. Data regarding patient age, comorbidities, laboratory data, and functional status were collected; functional status was evaluated using the Barthel index (BI) and nutritional status was evaluated using albumin concentrations and body mass index (BMI). Mean (±SD) BI and BMI were 75±16 and 22±4 kg/m2, respectively. BI (hazard ratio [HR] 0.96; 95% confidence interval [CI] 0.94–0.99, P=0.004), BMI (HR 0.85; 95% CI 0.75–0.95, P=0.003), atrial fibrillation (AF; HR 5.31; 95% CI 2.12–13.30, P<0.001), and ejection fraction (EF; HR 0.94; 95% CI 0.91–0.98, P=0.003) were independent predictors of mortality. Patients were divided into 2 groups based on BI (BI >75, n=71; and BI <70, n=36). Survival after IB was significantly lower for the lower BI group (P<0.001, log-rank test). After propensity score matching, post-IB survival remained significantly lower in the lower BI group (P=0.02).Conclusions:BI, BMI, AF, and EF were independently associated with all-cause mortality after IB for CLI. BI and BMI may be useful in identifying and optimizing treatment for high-risk frail patients.
