Cox Analysis

We evaluated whether underweight status is associated with poor prognosis in patients with peripheral artery disease (PAD) with claudication, excluding critical limb ischemia. We identified 441 claudicants hospitalized for cardiovascular disease between 2005 and 2012. Patients were divided into 4 groups according to body mass index (BMI): an underweight group (BMI < 18.5 kg/m2; n = 48), a normal group (BMI = 18.5-25.0 kg/m2; n = 286), an overweight group (BMI = 25.0-30.0 kg/m2; n = 92), and an obese group (BMI ≥ 30.0 kg/m2; n = 15). The mean follow-up period was 3.5 ± 1.9 years. The underweight group had significantly lower levels of hemoglobin, albumin, estimated glomerular filtration rate, triglycerides, and hemoglobin A1c; higher levels of C-reactive protein and B-type natriuretic peptide; and a higher prevalence of hemodialysis. The incidence of all-cause death and cardiovascular death was significantly higher in the underweight group (underweight vs normal, 77.1% vs 33.0%; P < .001 and 43.3% vs 14.4%; P < .001, respectively). In a multivariate Cox analysis, underweight status was an independent predictor of all-cause death (hazard ratio, 2.53; 95% confidence interval, 1.58-4.18; P < .001). Therefore, promoting weight gain, as well as managing cardiovascular disease, may be important for underweight patients with PAD.

Background: Patients with peripheral artery disease have a high risk of future cardiovascular disease events and mortality. Little is known about the changes in symptom classification over time in patients with peripheral artery disease and the association of changes in symptom classification with subsequent cardiovascular disease events. Methods: In this analysis of the EUCLID trial (Examining Use of Ticagrelor in Peripheral Artery Disease), we examined the changes in Rutherford classification (RC) of patients over 12 months. We examined the baseline characteristics of patients by change in symptom classification at 12 months (improved=decreased RC, no change, or worsened=increased RC), and the association between changes in symptom classification (RC) at 12 months and subsequent cardiovascular disease events. Results: Among 12 759 patients, 3240 (25%) were classified as improved by RC at 12 months, 8132 (64%) as no change, and 1387 (11%) as worsened. At 12 months, many patients who were asymptomatic or had mild/moderate claudication at enrollment had no change in symptom classification over 12 months (73.7% and 70.9%). Patients who worsened over 12 months were more likely to have comorbidities (diabetes mellitus and prior myocardial infarction) and more events (myocardial infarction, amputation, and major bleeding) by 12 months postrandomization, all P <0.001. Worsened symptom classification over 12 months was associated with increased risk of all-cause death (adjusted hazard ratio, 1.29 [95% CI, 1.03–1.62]), major amputation (adjusted hazard ratio, 4.12 [95% CI, 2.46–6.88]), and a composite of cardiovascular death, myocardial infarction, or stroke (adjusted hazard ratio, 1.30 [95% CI, 1.05–1.62]), all P <0.05 after 12 months postrandomization. Conclusions: Patients with comorbidities and prior history of cardiovascular disease events at baseline and within the first 12 months of the trial were more likely to have worsened symptom classification at 12 months. Worsening symptom classification over 12 months was associated subsequently with an increased risk of all-cause death, amputation, and a composite of cardiovascular death, myocardial infarction, or stroke.

Abstract Peripheral artery disease (PAD) is a major cause of acute and chronic illness, with extremely poor prognosis that remains underdiagnosed and undertreated. Trimethylamine-N-Oxide (TMAO), a gut derived metabolite, has been associated with atherosclerotic burden. We determined plasma levels of TMAO by mass spectrometry and evaluated their association with PAD severity and prognosis. 262 symptomatic PAD patients (mean age 70 years, 87% men) categorized in intermittent claudication (IC, n = 147) and critical limb ischemia (CLI, n = 115) were followed-up for a mean average of 4 years (min 1-max 102 months). TMAO levels were increased in CLI compared to IC (P < 0.001). Receiver operating characteristic (ROC) curves for severity (CLI) rendered a cutoff of 2.26 µmol/L for TMAO (62% sensitivity, 76% specificity). Patients with TMAO > 2.26 µmol/L exhibited higher risk of cardiovascular death (sub-hazard ratios ≥2, P < 0.05) that remained significant after adjustment for confounding factors. TMAO levels were associated to disease severity and CV-mortality in our cohort, suggesting an improvement of PAD prognosis with the measurement of TMAO. Overall, our results indicate that the intestinal bacterial function, together with the activity of key hepatic enzymes for TMA oxidation (FMO3) and renal function, should be considered when designing therapeutic strategies to control gut-derived metabolites in vascular patients.

ObjectiveIn patients with chronic coronary or peripheral artery disease enrolled in the Cardiovascular Outcomes for People Using Anticoagulation Strategies trial, randomised antithrombotic treatments were stopped after a median follow-up of 23 months because of benefits of the combination of rivaroxaban 2.5 mg two times per day and aspirin 100 mg once daily compared with aspirin 100 mg once daily. We assessed the effect of switching to non-study aspirin at the time of early stopping.MethodsIncident composite of myocardial infarction, stroke or cardiovascular death was estimated per 100 person-years (py) during randomised treatment (n=18 278) and after study treatment discontinuation to non-study aspirin (n=14 068).ResultsDuring randomised treatment, the combination compared with aspirin reduced the composite (2.2 vs 2.9/100 py, HR: 0.76, 95% CI 0.66 to 0.86), stroke (0.5 vs 0.8/100 py, HR: 0.58, 95% CI 0.44 to 0.76) and cardiovascular death (0.9 vs 1.2/100 py, HR: 0.78, 95% CI 0.64 to 0.96). During 1.02 years after early stopping, participants originally randomised to the combination compared with those randomised to aspirin had similar rates of the composite (2.1 vs 2.0/100 py, HR: 1.08, 95% CI 0.84 to 1.39) and cardiovascular death (1.0 vs 0.8/100 py, HR: 1.26, 95% CI 0.85 to 1.86) but higher stroke rate (0.7 vs 0.4/100 py, HR: 1.74, 95% CI 1.05 to 2.87) including a significant increase in ischaemic stroke during the first 6 months after switching to non-study aspirin.ConclusionDiscontinuing study rivaroxaban and aspirin to non-study aspirin was associated with the loss of cardiovascular benefits and a stroke excess.Trial registration numberNCT01776424.

We evaluated angiogenin as a prospective biomarker in peripheral artery disease (PAD) patients with and without claudication symptoms. A pilot study suggested an elevation of angiogenin in critical limb ischemia. However, in PAD patients, the predictive value of angiogenin has not yet been evaluated. For this purpose, 342 patients with PAD (age: 69 ± 10 years, 34.5% women) were followed-up for 7 years in a cross-sectional study. Angiogenin was measured by enzyme-linked immunosorbent assay. All-cause and cardiovascular mortality were analyzed by Cox regression. Angiogenin levels were higher in men ( P = .001) and were associated with patient waist-to-hip ratio ( P < .001), fasting triglycerides ( P = .011), and inversely with estimated glomerular filtration rate ( P = .009). However, angiogenin showed no association with age, characteristics of diabetes, markers of lipid metabolism, or C-reactive protein. Angiogenin did not correlate with markers of angiogenesis such as vascular endothelial growth factor, angiopoietin-2, or tie-2. Furthermore, angiogenin was not associated with PAD Fontaine stages or with patient ankle-brachial index in addition to all-cause mortality (hazard ratio [HR] = 1.09 [95% CI: 0.89-1.34]) or cardiovascular morality (HR = 1.05 [0.82-1.35]). These results suggest that angiogenin does not provide further information regarding outcome prediction in patients with PAD.

Background: Chronic limb-threatening ischemia is a severe form of peripheral artery disease that leads to high rates of amputation and mortality if left untreated. Bypass surgery and antegrade endovascular revascularization through femoral artery access from either side are accepted as conventional treatment modalities for critical limb ischemia. The retrograde pedal access revascularization is an alternative treatment modality useful in specific clinical scenarios; however, these indications have not been well described in literature. This case report highlights the use of retrograde pedal access approach as primary treatment modality in a patient with an extensive comorbidities precluding general anesthesia nor supine positioning. Case Presentation: The patient is a 60-year-old female with multiple severe cardiopulmonary comorbidities presenting with dry gangrene of the right great toe. Her comorbidities and inability to tolerate supine positioning precluded her from receiving open surgery, general anesthesia or monitored sedation, or percutaneous femoral access. Rather, the patient underwent ankle block and retrograde endovascular revascularization via dorsalis pedis artery access without post-operative complications. Discussion: The prevalence of comorbidities related to peripheral artery disease is increasing and with it the number of patients who are not optimal candidates for conventional treatment methods for critical limb ischemia. The retrograde pedal access revascularization as initial treatment modality offers these patients an alternative limb salvaging treatment option.

Effective revascularization of the patient with peripheral artery disease is about more than the procedure. The approach to the patient with symptom-limiting intermittent claudication or limb-threatening ischemia begins with understanding the population at risk and variation in clinical presentation. The urgency of revascularization varies significantly by presentation; from patients with intermittent claudication who should undergo structured exercise rehabilitation before revascularization (if needed) to those with acute limb ischemia, a medical emergency, who require revascularization within hours. Recent years have seen the rapid development of new tools including wires, catheters, drug-eluting technology, specialized balloons, and biomimetic stents. Open surgical bypass remains an important option for those with advanced disease. The strategy and techniques employed vary by clinical presentation, lesion location, and lesion severity. There is limited level 1 evidence to guide practice, but factors that determine technical success and anatomic durability are largely understood and incorporated into decision-making. Following revascularization, medical therapy to reduce adverse limb outcomes and a surveillance plan should be put in place. There are many hurdles to overcome to improve the efficacy of lower extremity revascularization, such as restenosis, calcification, microvascular disease, silent embolization, and tools for perfusion assessment. This review highlights the current state of revascularization in peripheral artery disease with an eye toward technologies at the cusp, which may significantly impact current practice.

Background: Galectin-3 is involved in the regulation of inflammation and the formation of fibrosis and has been liked to atherosclerosis. However, there are no studies investigating prospective associations of galectin-3 with incidence of lower-extremity peripheral artery disease (PAD). Methods: Among 9,827 ARIC participants without a history of PAD, we investigated whether galectin-3 (measured at visit 4 [1996-98]) was associated with incident clinical PAD through 2013, defined as hospitalizations with PAD diagnosis or leg revascularization. We defined PAD cases with rest pain or tissue loss as critical limb ischemia (CLI). We constructed Cox models with galectin-3 modeled categorically (quartiles) and continuously (log transformed). Results: During a median follow-up of 15.8 years, 287 participants developed PAD (105 incident CLI cases). In demographically adjusted models, galectin-3 demonstrated a dose-response association with incident PAD: hazard ratios (HRs) 2.55 (95% CI 1.80-3.61) and 1.69 (1.18-2.41) for the highest and second highest quartiles, as compared to the lowest quartile (Table; Model 1). Additional adjustment for traditional cardiovascular risk factors attenuated the associations, although the highest quartile remained borderline significant (HR 1.44 [0.99-2.07], p=0.051, Table: Model 2) and galectin-3 as a continuous variable remained significant (1.15 [1.02-1.29]). Similar results were observed for the association of galectin-3 with CLI. Conclusions: Galectin-3 was modestly associated with future risk of clinical PAD events in a community-based cohort, supporting the involvement of inflammation and fibrosis in the development of clinical PAD.

Aims Secondary prevention in patients with coronary artery disease and peripheral artery disease involves antithrombotic therapy and optimal control of cardiovascular risk factors. In the Cardiovascular Outcomes for People Using Anticoagulation Strategies (COMPASS) study, adding low-dose rivaroxaban on top of aspirin lowered cardiovascular events, but there is limited data about risk factor control in secondary prevention. We studied the association between risk factor status and outcomes, and the impact of risk factor status on the treatment effect of rivaroxaban, in a large contemporary population of patients with coronary artery disease or peripheral artery disease. Methods and results We reported ischemic events (cardiovascular death, stroke, or myocardial infarction) in participants from the randomized, double-blind COMPASS study by individual risk factor (blood pressure, smoking status, cholesterol level, presence of diabetes, body mass index, and level of physical activity), and by number of risk factors. We compared rates and hazard ratios of patients treated with rivaroxaban plus aspirin vs aspirin alone within each risk factor category and tested for interaction between risk factor status and antithrombotic regimen. Complete baseline risk factor status was available in 27,117 (99%) patients. Status and number of risk factors were both associated with increased risk of ischemic events. Rates of ischemic events (hazard ratio 2.2; 95% confidence interval 1.8–2.6) and cardiovascular death (hazard ratio 2.0; 1.5–2.7) were more than twofold higher in patients with 4–6 compared with 0–1 risk factors ( p < 0.0001 for both). Rivaroxaban reduced event rates independently of the number of risk factors ( p interaction 0.93), with the largest absolute benefit in patients with the highest number of risk factors. Conclusion More favorable risk factor status and low-dose rivaroxaban were independently associated with lower risk of cardiovascular events.
