Statin Use

Background: Statin use is recommended in patients with peripheral arterial disease (PAD) due to its morbidity and mortality benefits. However, the effect of statins on limb salvage in PAD is unclear. We examined the effect of statins on survival and limb salvage among PAD patients undergoing surgical or endovascular intervention. Methods: PAD patients were identified who underwent intervention between 2009 and 2010. Information was collected from electronic medical records and the Social Security Death Index. Univariate analysis was used to determine predictors of ongoing statin use. Survival and freedom from amputation were determined using KM plots and adjusted hazard ratios by Cox regression. Results: A total of 488 PAD patients underwent surgical (n=297) or endovascular (n=191) intervention. 39% were African-American, 44% were female, 41% received statins, 56% received antiplatelet medications, 26% received oral anticoagulants, 9% required a major amputation, and 11% died during follow-up of up to 88 months. Statin users were more often male (p=0.03), caucasian (p=0.03), smokers (p<0.01), and had higher comorbidities such as CAD (p<0.01), hypertension (p<0.01), and diabetes (p<0.01). Antiplatelet use was not associated with amputations (p=0.13), but did lower mortality (p<0.01). Dual antiplatelet therapy did not show any benefit over monotherapy for mortality (p=0.3) or amputations (p=0.4). Statin use was associated with lower mortality (p=0.04), and improved limb salvage (hazard ratio, 0.3; 95% confidence interval, 0.2-0.6) after adjusting for severity of disease as well as antiplatelet and anticoagulation use. Conclusion: Statin use in PAD patients with interventions was associated with improved limb-salvage and survival. Despite existing guidelines, statin therapy was disappointingly low in our PAD population, and efforts will be made to increase use across our health system.

Abstract. Background: Multilevel peripheral arterial disease is frequently observed in patients with intermittent claudication or critical limb ischemia. This report evaluates the efficacy of one-stage hybrid revascularization in patients with multilevel arterial peripheral disease. Patients and methods: A retrospective analysis of a prospective database included all consecutive patients treated by a hybrid approach for a multilevel arterial peripheral disease. The primary outcome was the patency rate at 6 months and 1 year. Secondary outcomes were early and midterm complication rate, limb salvage and mortality rate. Statistical analysis, including a Kaplan-Meier estimate and univariate and multivariate Cox regression analyses were carried out with the primary, primary assisted and secondary patency, comparing the impact of various risk factors in pre- and post-operative treatments. Results: 64 patients were included in the study, with a mean follow-up time of 428 days (range: 4 − 1140). The technical success rate was 100 %. The primary, primary assisted and secondary patency rates at 1 year were 39 %, 66 % and 81 %, respectively. The limb-salvage rate was 94 %. The early mortality rate was 3.1 %. Early and midterm complication rates were 15.4 % and 6.4 %, respectively. The early mortality rate was 3.1 %. Conclusions: The hybrid approach is a major alternative in the treatment of peripheral arterial disease in multilevel disease and comorbid patients, with low complication and mortality rates and a high limb-salvage rate.

Background: We compared medical secondary prevention in patients with peripheral arterial disease stage II (Fontaine) located in the femoro-popliteal artery managed by vascular surgeons and medical doctors / angiologists in our multidisciplinary vascular center. Patients and methods: We retrospectively analyzed demission protocols of in-hospital treatments between 01.01.2007 and 20.06.2008. Results: We surveyed 264 patients (54.2 % women; mean age 67.52 ± 8.98 yrs), 179 (67.8 %) primarily treated by medical doctors / angiologists and 85 (32.2 %) primarily managed by vascular surgeons. Medical doctors / angiologists treated more women (n = 109) than men (n = 34), (p = 0.002) and documented smoking and diabetes mellitus more often (p < 0.001) than vascular surgeons. Besides, patients had similar cardiovascular risk profiles and concomitant diseases, vascular surgeons prescribed 5.47 ± 2.26 drugs, medical doctors / angiologists 6.37 ± 2.67 (p = 0.005). Overall, 239 (90.5 %) patients were on aspirin, 180 (68.2 %) on clopidogrel, and 18 (6.9 %) on oral anticoagulants. Significantly more patients treated by medical doctors / angiologists received clopidogrel (169 versus 11; p < 0.001), significantly more surgical patients received oral anticoagulants (11 versus 7; p = 0.016). The number of patients without prescriptions for any antithrombotic therapy was 6 (6.9 %) in patients treated by vascular surgeons and 0 (0 %) in patients managed by medical doctors / angiologists (p = 0.001). Prescription-rates of β-blockers, ACE-inhibitors, Angiotensin II-antangonists, calcium channel blockers, and diuretics were statistically not different between the two disciplines, but statins were prescribed significantly more often by medical doctors / angiologists (139 versus 49; p < 0001). With the exceptions of Clopidogrel (women > men) and diuretics (men > women) we observed no gender-specific prescriptions. Conclusions: We observed high prescriptions rates of secondary medical prevention in patients primarily treated by medical doctors / angiologists and vascular surgeons. We believe that this result is highly influenced by our multidisciplinary approach. Nevertheless, efforts have to be made to raise vascular surgeon’s awareness of statin use and complete prescription of antithrombotic and antiplatelet drugs.

Abstract Introduction Antiplatelet therapy is the cornerstone of treatment for many atherosclerotic vascular pathologies including peripheral arterial disease (PAD). Patients with PAD often have comorbid conditions that require complex antithrombotic therapy, i.e. combined antiplatelet and anticoagulation. Methods All adult patients undergoing ankle brachial index (ABI) measurements were included in the study. ABI values between 1.00 and 1.40 were considered normal, and values below 1.00 or above 1.40 were considered PAD. Demographic, comorbidity and outcome data were obtained using diagnostic codes from the electronic health record. Three medication classes were analyzed: aspirin, non-aspirin oral antiplatelets (e.g. P2Y12 inhibitors) and oral anticoagulants (warfarin and the direct oral anticoagulants). Medication use was determined for patients who had been on a medication for at least one year. Cox proportional hazard analysis for the time to first bleeding event was analyzed. Bleeding was defined as any bleeding requiring medical evaluation (including clinically-relevant non-major bleeding and major bleeding). Results In all, 40,144 patients were included in the analysis (mean age 66±15, 43% female). Patients with PAD were more likely to be on double therapy (one antiplatelet with anticoagulation) (28% vs 19%) and triple therapy (dual antiplatelet with anticoagulation) (10% vs 4%). Unadjusted hazard ratios for bleeding risk showed increased risk of bleeding for patients with PAD (1.18, 95% confidence interval [CI]: 1.08–1.29), though the association is no longer present after adjustment for antithrombotic therapy. Adjusting for age, sex and PAD class, compared to no antithrombotic therapy, there was increased risk of bleeding for monotherapy (1.91, 95% CI: 1.61–2.26), double therapy (3.40, 95% CI: 2.89–4.00) and triple therapy (5.00, 95% CI: 4.21–5.96). Among medications, aspirin and anticoagulant use was independently associated with the greatest increase in risk of bleeding. Conclusion Patients in PAD are at increased risk of bleeding secondary to antithrombotic therapy. Complex antithrombotic therapy with double or triple therapy confer additional bleeding risk, particularly regimens containing aspirin and oral anticoagulants.

Introduction: Chronic kidney disease (CKD) is common in patients with peripheral arterial disease (PAD), but patients with severe CKD have been excluded from many trials and no objective performance goals exist for patients with PAD and CKD. We sought to analyze the association between severity of CKD and cardiovascular and limb-related outcomes among patients with PAD. Methods: We reviewed records of all patients at our institution who underwent lower extremity angiography between 2006 and 2013. We analyzed outcomes including mortality, major adverse cardiovascular event (MACE) rate, and major adverse limb event (MALE) rate according to clinical stage of CKD, determined by calculating each patient’s glomerular filtration rate using the Cockcroft-Gault equation. We used Cox proportional hazard modeling to account for covariates, along with Bonferroni correction for multiple comparisons. Results: Of 773 patients, 45% had CKD stage 3-5. The patients had a median age of 67, were 58% male, 51% diabetic, and 57% presented with critical limb ischemia (CLI). During a median follow-up time of 3.2 years, patients with higher stages of CKD had an increased rate of death (Figure 1, p<0.001). CKD stages 4 and 5 were significant predictors of mortality in a multivariate model (HR 3.2 and 2.4 vs. CKD 1, P<0.001 and P<0.01, respectively). An analysis of MACE by CKD stage demonstrated similar results (CKD 4 HR 2.2, p<0.01; CKD 5 HR 2.0, p<0.01). CKD stage also predicted MALE in a univariate analysis (p<0.01), driven by increased limb events among patients with CKD stage 5 (p<0.01). However, CKD stage did not demonstrate a significantly increased hazard of MALE in a multivariate Cox model. Conclusions: Patients with PAD who also have CKD have increased rates of adverse outcomes. This relationship seems to be more robust for major cardiovascular events and overall mortality than for major limb events. Future studies should investigate how management of PAD should differ for patients with CKD.
