Background: Patients with peripheral artery disease (PAD) fall under the category of a very high cardiovascular risk. Although, consequent lipid lowering therapy (LLT) is advised, only sparse data on attained target level in PAD exists. Objectives: We aimed to analyse contemporary guideline recommendations for LLT in symptomatic PAD patients. Methods: monocentric, prospective, observational study involving 200 symptomatic PAD patients. Guideline target level attainment and LLT were analysed between 2017 and 2019. Results: Overall 78.5% of the patients were on statin therapy, mainly of high intensity with atorvastatin in 50% and rosuvastatin in 33% of the cases. Average statin dosage adjusted for simvastatin was 55 mg/d. Low density lipoproteincholesterol (LDL-C) was <1.8 mmol/L in 53% and <1.4 mmol/L in 34% of the cases. Mean LDL-C levels were at 1.85 ± 0.88 mmol/L. We observed no difference in the treatment and the target level attainment of patients with a stable PAD (intermittent claudication) or chronic critical PAD. However, patients with ≥1 vascular region affected (i.e. coronary and/or cerebrovascular) were treated more intensively and had lower LDL-C levels than patients with PAD alone. Conclusion: It appears that there is more awareness and improvement of previously documented undertreatment of LDL-C levels in symptomatic PAD patients. Although statin treatment is initiated in the majority of patients, our findings call for a continuously intensified LLT in symptomatic PAD patients.

Abstract Introduction The International Atherosclerosis Society (IAS) has proposed “severe familial hypercholesterolemia (FH)” as a FH phenotype with the highest cardiovascular risk. Coronary artery disease (CAD) represents a major atherosclerotic change in FH patients. Given their higher LDL-C level and atherogenic clinical features, more extensive formation of atherosclerosis cardiovascular disease including not only CAD but stroke/peripheral artery disease (PAD) may more frequently occur in severe FH. Methods 481 clinically-diagnosed heterozygous FH subjects were analyzed. Severe FH was defined as untreated LDL-C>10.3 mmol/l, LDL-C>8.0 mmol/l+ 1 high-risk feature, LDL-C>4.9 mmol/l + 2 high-risk features or presence of clinical ASCVD according to IAS proposed statement. Cardiac (cardiac death and ACS) and non-cardiac (stroke and peripheral artery disease) events were compared in severe and non-severe FH subjects. Results Severe FH was identified in 50.1% of study subjects. They exhibit increased levels of LDL-C and Lipoprotein (a) with a higher frequency of LDLR mutation. Furthermore, a proportion of %LDL-C reduction>50% was greater in severe FH under more lipid-lowering therapy (Table). However, during the observational period (median=6.3 years), severe FH was associated with a 5.9-fold (95% CI, 2.05–25.2; p=0.004) and 5.8-fold (95% CI, 2.02–24.7; p=0.004) greater likelihood of experiencing cardiac-death/ACS and stroke/PAD, respectively (picture). Multivariate analysis demonstrated severe FH as an independent predictor of both cardiac-death/ACS (hazard ratio=3.39, 95% CI=1.12–14.7, p=0.02) and stroke/PAD (hazard ratio=3.38, 95% CI=1.16–14.3, p=0.02) events. Clinical characteristics of severe FH Non-severe FH Severe FH P-value Baseline LDL-C (mmol/l) 5.3±1.5 6.6±2.0 <0.0001 Lp(a) (mg/dl) 15 [8–28] 21 [10–49] <0.0001 LDLR mutation (%) 49.6% 58.9% 0.00398 On-treatment LDL-C (mmol) 133 [106–165] 135 [103–169] 0.9856 %LDL-C reduction>50% 21.3% 49.8% <0.0001 High-intensity statin (%) 13.3% 42.3% <0.0001 PCSK9 inhibitor (%) 6.3% 21.2% <0.0001 Clinical outcome Conclusions Severe FH subjects exhibit substantial atherosclerotic risks for coronary, carotid and peripheral arteries despite lipid lowering therapy. Our finding underscore the screening of systemic arteries and the adoption of further stringent lipid management in severe FH patients.

Peripheral artery disease (PAD) is estimated to affect approximately 8.5 million individuals in the US above the age of 40, and is associated with significant morbidity, mortality, and impairment. Despite the significant adverse limb and cardiovascular (CV) outcomes seen in patients with PAD, there is typically less attention paid to risk factor modification relative to other atherosclerotic diseases such as coronary artery disease (CAD) or stroke. In the current literature, statins have been shown to reduce mortality, major adverse CV events, major adverse limb events, and improve symptomatic outcomes in patients with PAD. In addition, proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are emerging as an additional lipid-lowering therapy for patients with PAD. However, despite current guideline recommendations based on growing evidence, PAD patients are consistently undertreated with lipid-lowering therapies. We provide an extensive literature review and evidence-based recommendations for the use of statins and PCSK9 inhibitors in patients with PAD.

Background Patients with peripheral artery disease are at increased risk of both major adverse cardiovascular events (MACEs) and limb events. The pathobiology of limb events is likely multifactorial. Observational studies suggest a benefit of statin therapy for reducing the risk of limb ischemic events while randomized trials demonstrate a benefit with more potent antithrombotic therapies, particularly those targeting thrombin. Whether the effects of these therapeutic pathways are independent and complementary is not known. Methods and Results The TRA 2°P‐TIMI 50 (Thrombin Receptor Antagonist in Secondary Prevention of Atherothrombotic Ischemic Events–Thrombolysis in Myocardial Infarction 50) trial demonstrated that vorapaxar significantly reduced MACEs and limb events. The purpose of the current analysis was to evaluate the association of statin use and intensity and the occurrence of MACEs and limb events in 5845 patients with symptomatic peripheral artery disease randomized in TRA 2°P‐TIMI 50 and then to understand whether statin use modified the benefits of vorapaxar for MACEs or limb ischemic events. We found that statin therapy was associated with significantly lower risk of MACEs (hazard ratio [HR], 0.77; 95% CI, 0.66–0.89; P <0.001) and limb ischemic events (HR, 0.73; 95% CI, 0.60–0.89; P =0.002). The benefit of vorapaxar for reducing MACEs and limb events was consistent regardless of background statin ( P ‐interaction=0.715 and 0.073, respectively). Event rates were lowest in patients receiving the combination of statin therapy and vorapaxar. Conclusions In conclusion, statin use and intensity is associated with significantly lower rates of MACEs and limb ischemic events. Thrombin inhibition with vorapaxar is effective regardless of background statin therapy. These results suggest that targeting both lipid and thrombotic risk in peripheral artery disease is necessary in order to optimize outcomes.

Abstract Funding Acknowledgements Type of funding sources: None. Background Peripheral artery disease (PAD) affects more than eight million Americans. However, several studies have shown that those patients are often undertreated, and that statin utilization is suboptimal.  American Heart Association guidelines highlight statins as the first-line lipid-lowering therapy to treat patients with PAD. Our objective with this meta-analysis was to further explore the impact of statins on PAD outcomes and examine whether the actual statin (high vs low intensity) dose impacts outcomes. Methods We performed a systematic review and meta-analysis according to the PRISMA guidelines. Any study that presented a comparison of statins vs no statins for PAD patients or compared high vs low intensity statins and provided outcomes with hazard ratio was considered as potentially eligible. The Medline (PubMed) database was searched up to August 30, 2020. A random effects meta-analysis was performed. Results In total, 38 studies and 275,670 patients were included in this meta-analysis. In total, 136,025 (49.34%) were on statins vs 139,645 (50.66%) who were not on statins. Statins had an association with a reduction in all cause-mortality by 42% (HR:0.58, 95% CI: 0.49-0.67, I2= 96.26%) and cardiovascular death by 43% (HR:0.57, 95% CI: 0.40-0.74, I2= 80.39%). Statins use was associated with an increase in amputation-free survival by 56% (HR:0.44, 95% CI: 0.30-0.58, I2 = 15%). The risk of amputation and loss of patency was reduced by 35% (HR:0.65, 95% CI:0.41-0.89, I2 = 86.91%), 46% (HR:0.54, 95% CI: 0.34-0.74, Ι2 = 0%), respectively. Statins use was also associated with a reduction in the risk of major adverse cardiovascular events (MACE) by 35% (HR:0.65, 95% CI: 0.51-0.80, I2= 93.22%) and the incidence of myocardial infarction (MI) by 41% (HR:0.59, 95% CI: 0.33-0.86, I2 = 76.78%). Among patients treated with statins, high-intensity treatment group was associated with a reduction in all cause-mortality by 36% (HR:0.64, 95% CI: 0.54-0.74, I2 = 96.49%) compared to patients treated with low intensity statins. Conclusion Statin treatment among patients with PAD was associated with a statistically significant reduction in all-cause mortality, cardiovascular mortality, MI, MACE, risk for amputation or loss of patency. Statins were also associated with a higher amputation free survival.

Abstract Background Although patients with familial heterozygous hypercholesterolemia (FH) have a high risk of early myocardial infarction (MI), the coronary artery disease (CAD) burden in FH patients with acute MI remains to be investigated. Methods The data for all consecutive patients hospitalized in 2012–2019 for an acute MI and who underwent coronary angiography were collected from a multicenter database (RICO database). FH (n = 120) was diagnosed using Dutch Lipid Clinic Network criteria (score ≥ 6). We compared the angiographic features of MI patients with and without FH (score 0–2) (n = 234) after matching for age, sex, and diabetes (1:2). Results Although LDL-cholesterol was high (208 [174–239] mg/dl), less than half of FH patients had chronic statin treatment. When compared with non-FH patients, FH increased the extent of CAD (as assessed by SYNTAX score; P = 0.005), and was associated with more frequent multivessel disease (P = 0.004), multiple complex lesions (P = 0.022) and significant stenosis location on left circumflex and right coronary arteries. Moreover, FH patients had more multiple lesions, with an increased rate of bifurcation lesions or calcifications (P = 0.021 and P = 0.036, respectively). In multivariate analysis, LDL-cholesterol levels (OR 1.948; 95% CI 1.090–3.480, P = 0.024) remained an independent estimator of anatomical complexity of coronary lesions, in addition to age (OR 1.035; 95% CI 1.014–1.057, P = 0.001). Conclusions FH patients with acute MI had more severe CAD, characterized by complex anatomical features that are mainly dependent on the LDL-cholesterol burden. Our findings reinforce the need for more aggressive preventive strategies in these high-risk patients, and for intensive lipid-lowering therapy as secondary prevention.
