The Association Between Metabolic Dysfunction-Associated Fatty Liver Disease and Peripheral Arterial Disease in the Chinese Population. Diabetes Metab Syndr Obes 2023; 16:373-384.

Abstract
PURPOSE Emerging evidence suggested that metabolic dysfunction-associated fatty liver disease (MAFLD) was significantly associated with atherosclerotic diseases. Atherosclerosis in the peripheral arteries is the most common cause of peripheral arterial disease (PAD), which has not been substantially controlled in the past. We aimed to investigate the association between MAFLD and PAD in the Chinese population. PATIENTS AND METHODS This observational study covered 102,115 participants who underwent health checkups with detailed examinations for PAD and MAFLD. PAD was measured by ankle-brachial index, and MAFLD was diagnosed by abdominal ultrasound. The generalized linear mixed models and random-effects Cox proportional hazards models were used to analyze the relationship between MAFLD and PAD. RESULTS The baseline characteristics showed that patients with MAFLD had higher prevalence of PAD compared with those without MAFLD (2.7% vs 2.2%). Compared to non-MAFLD, the individuals with MAFLD were associated with a higher risk of the presence of PAD (adjusted odds ratio: 1.30, 95% confidence interval (CI): 1.19-1.42, P < 0.001). In the prospective cohort study, 6833 participants underwent a follow-up of 2.76 (standard deviation: 1.36) years, and MAFLD at baseline was a higher risk of associated with incident PAD (adjusted hazards ratio: 1.67, 95% CI: 1.17-2.38, P = 0.005). Moreover, with the accumulation of metabolic abnormalities, the risk of the PAD was increased in the individuals with MAFLD. Furthermore, MAFLD attributed risk of PAD was more evident in participants without metabolic comorbidities. CONCLUSION MAFLD was associated with a significantly higher risk for the prevalence and incidence of PAD in the Chinese population. The finding suggested that individuals with MAFLD are not only have a higher risk of coronary heart diseases but also have an increased risk of atherosclerosis in peripheral arteries.

Abstract
PURPOSE The purpose of this study was to explore the perceptions of health professionals regarding the ideal design of a remotely delivered diabetes-related foot disease (DFD) secondary prevention program. METHODS A qualitative study involving 33 semistructured phone interviews was conducted with health professionals with experience managing DFD. Interviews discussed the role of health professionals in managing DFD, their experience in using telehealth, perceived management priorities, preferences for a secondary prevention management program, and perceived barriers and facilitators for such a program. Interviews were audio-recorded and transcribed, and inductive thematic analysis was used to derive key themes. RESULTS Three themes were derived: (1) barriers in current model of DFD care, (2) facilitators and ideas for a remotely delivered secondary prevention program, and (3) potential challenges in implementation. DFD care remains acute-care focused, with variability in access to care and a lack of "clinical ownership." Patients were perceived as often having poor knowledge and competing priorities, meaning engagement in self-care remains poor. Participants felt a remote secondary prevention program should be simple to follow and individualized to patients' context, with embedded support from a case manager and local multidisciplinary service providers. Challenges to implementation included limited DFD awareness, poor patient motivation, patient-related issues with accessing and using technology, and the inability to accurately assess and treat the foot over telehealth. CONCLUSIONS Health professionals felt that an ideal remotely delivered secondary prevention program should be tailored to patients' needs with embedded support from a case manager and complemented with multidisciplinary collaboration with local service providers.

Abstract
Background Remotely delivered interventions may be more efficient in controlling multiple risk factors in people with diabetes. Purpose To pool evidence from randomized controlled trials testing remote management interventions to simultaneously control blood pressure, blood glucose and lipids. Data Sources PubMed/Medline, EMBASE, CINAHL and the Cochrane library were systematically searched for randomized controlled trials (RCTs) until 20th June 2021. Study Selection Included RCTs were those that reported participant data on blood pressure, blood glucose, and lipid outcomes in response to a remotely delivered intervention. Data Extraction Three authors extracted data using a predefined template. Primary outcomes were glycated hemoglobin (HbA1c), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-c), systolic and diastolic blood pressure (SBP & DBP). Risk of bias was assessed using the Cochrane collaboration RoB-2 tool. Meta-analyses are reported as standardized mean difference (SMD) with 95% confidence intervals (95%CI). Data Synthesis Twenty-seven RCTs reporting on 9100 participants (4581 intervention and 4519 usual care) were included. Components of the remote management interventions tested were identified as patient education, risk factor monitoring, coaching on monitoring, consultations, and pharmacological management. Comparator groups were typically face-to-face usual patient care. Remote management significantly reduced HbA1c (SMD -0.25, 95%CI -0.33 to -0.17, p<0.001), TC (SMD -0.17, 95%CI -0.29 to -0.04, p<0.0001), LDL-c (SMD -0.11, 95%CI -0.19 to -0.03, p=0.006), SBP (SMD -0.11, 95%CI -0.18 to -0.04, p=0.001) and DBP (SMD -0.09, 95%CI -0.16 to -0.02, p=0.02), with low to moderate heterogeneity (I²= 0 to 75). Twelve trials had high risk of bias, 12 had some risk and three were at low risk of bias. Limitations Heterogeneity and potential publication bias may limit applicability of findings. Conclusions Remote management significantly improves control of modifiable risk factors.

Abstract
Approximately 6% of adults worldwide have atherosclerosis and thrombosis of the lower limb arteries (peripheral artery disease (PAD)) and the prevalence is rising. PAD causes leg pain, impaired health-related quality of life, immobility, tissue loss and a high risk of major adverse events, including myocardial infarction, stroke, revascularization, amputation and death. In this Review, I describe the pathophysiology, presentation, outcome, preclinical research and medical management of PAD. Established treatments for PAD include antithrombotic drugs, such as aspirin and clopidogrel, and medications to treat dyslipidaemia, hypertension and diabetes mellitus. Randomized controlled trials have demonstrated that these treatments reduce the risk of major adverse events. The drug cilostazol, exercise therapy and revascularization are the current treatment options for the limb symptoms of PAD, but each has limitations. Novel therapies to promote collateral and new capillary growth and treat PAD-related myopathy are under investigation. Methods to improve the implementation of evidence-based medical management, novel drug therapies and rehabilitation programmes for PAD-related pain, functional impairment and ischaemic foot disease are important areas for future research.

Cohort Study Examining the Prevalence and Relationship with Outcome of Standard Modifiable Risk Factors in Patients with Peripheral Artery Occlusive and Aneurysmal Disease. Eur J Vasc Endovasc Surg 2021; 63:305-313. [PMID: 34916106 DOI: 10.1016/j.ejvs.2021.10.039] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2021] [Revised: 09/20/2021] [Accepted: 10/09/2021] [Indexed: 11/03/2022]
Abstract
OBJECTIVE The aim was to examine the presentation and outcome of patients with peripheral artery occlusive and aneurysmal disease (POAD) in relation to standard modifiable cardiovascular risk factors (SMuRFs; i.e., hypertension, diabetes, hypercholesterolaemia, and smoking). METHODS A total of 2 129 participants with POAD were recruited from three vascular clinics in Queensland, Australia. SMuRFs were defined using established criteria. Participants were followed via outpatient appointments and linked data to record the primary outcome event of major adverse cardiovascular events (MACE). The association between SMuRFs and MACE was assessed using Cox proportional hazard analysis. Subanalyses examined the association of individual SMuRFs with MACE and assessed findings separately in participants with occlusive and aneurysmal disease. RESULTS At recruitment 71 (3.3%), 551 (25.9%), 977 (45.9%), 471 (22.1%), and 59 (2.8%) participants had zero, one, two, three, and four SMuRFs. During a median follow up of 2.6 (interquartile range 0.4, 6.2) years, the risk of MACE was progressively higher with the increasing numbers of SMuRFs (adjusted hazard ratio [HR] 95% confidence interval [CI] 4.09, 1.29 - 12.91; 4.28, 1.37 - 13.41; 5.82, 1.84 - 18.39; and 9.42, 2.77 - 32.08; for one, two, three, or four SMuRFs, respectively) by comparison with those who were SMuRF-less at recruitment. Participants with occlusive disease were significantly more likely to have a greater number of SMuRFs than those with aneurysmal disease. In a subanalysis, there was a significantly higher risk of MACE with three or four SMuRFs in participants presenting with either occlusive or aneurysmal disease compared with those who were SMuRF-less. Hypertension, diabetes, and smoking but not hypercholesterolaemia were independently associated with increased risk of MACE. CONCLUSION Very few patients presenting with POAD had no SMuRFs. There was a progressive increase in the risk of MACE in relation to the number of SMuRFs identified at entry.

Abstract
PURPOSE OF REVIEW To provide an overview of the associations between elevated blood pressure and lipoprotein (a) and possible causal links, as well as data on the prevalence of elevated lipoprotein (a) in a cohort of hypertensive patients. RECENT FINDINGS Elevated lipoprotein (a) is now considered to be an independent and causal risk factor for atherosclerotic cardiovascular disease and calcific aortic valve disease. Despite this, there are limited data demonstrating an association between elevated lipoprotein (a) and hypertension. Further, there is limited mechanistic data linking lipoprotein (a) and hypertension through either renal impairment or direct effects on the vasculature. Despite the links between lipoprotein (a) and atherosclerosis, there are limited data demonstrating an association with hypertension. Evidence from our clinic suggests that ~ 30% of the patients in this at-risk, hypertensive cohort had elevated lipoprotein (a) levels and that measurement of lipoprotein (a) maybe useful in risk stratification.

Abstract
Background and aims The increasing prevalence of diabetes mellitus is causing a massive growth of peripheral artery disease incidences, a disabling complication of diabetic atherosclerosis, which leads often to the amputation of the affected limb. Critical limb ischemia is the terminal disease stage, which requires a prompt intervention to relieve pain and save limbs. However, patients undergoing revascularization often suffer from cardiovascular, cerebrovascular and major adverse limb events with poor outcomes. Furthermore, the same procedure performed in apparently similar patients has various outcomes and lack of an outcome predictive support causes a high lower limb arterial revascularization rate with disastrous effects for patients. We collected the main risk factors of major adverse limb events in a more readable and immediate format of the topic, to propose an overview of parameters to manage effectively peripheral artery disease patients and to propose basics of a new predictive tool to prevent from disabling vascular complications of the disease. Methods Most recent and updated literature about the prevalence of major adverse limb events in peripheral artery disease was reviewed to identify possible main predictors. Results In this article, we summarized major risk factors of limb revascularization failure and disabling vascular complications collecting those parameters principally responsible for major adverse limb events, which provides physio-pathological explanation of their role in peripheral artery disease. Conclusion We evaluated and listed a panel of possible predictors of MALE (Major Adverse Limb Event) in order to contribute to the development of a predictive score, based on a summary of the main risk factors reported in scientific articles, which could improve the management of peripheral artery disease by preventing vascular accidents.

The Potential Benefits and Costs of an Intensified Approach to Low Density Lipoprotein Cholesterol Lowering in People with Abdominal Aortic Aneurysm. Eur J Vasc Endovasc Surg 2021; 62:643-650.

Abstract
OBJECTIVE The aims of this study were to assess the incidence of major vascular events (MVE) and peripheral vascular events (PVE) in people with a small asymptomatic abdominal aortic aneurysm (AAA) and model the theoretical benefits and costs of an intensified low density lipoprotein cholesterol (LDL-C) lowering programme. METHODS A total of 583 participants with AAAs measuring 30 - 54 mm were included in this study. The control of LDL-C and prescription of lipid lowering drugs were assessed by dividing participants into approximately equal tertiles depending on their year of recruitment into the study. The occurrence of MVE (myocardial infarction, stroke, cardiovascular death, and coronary or non-coronary revascularisation) and PVE (non-coronary revascularisation, AAA repair, and major amputation) were recorded prospectively, and the incidence of these events was calculated using Kaplan-Meier analysis. The relative risk reduction reported for these events in a previous randomised control trial (RCT) was then applied to these figures to model the absolute risk reduction and numbers needed to treat (NTT) that could theoretically be achieved with a mean LDL-C lowering of 1 mmol/L. The maximum allowable expense for a cost effective intensive LDL-C lowering programme was estimated using a cost utility analysis. RESULTS At entry, only 28.5% of participants had an LDL-C of < 1.8 mmol/L and only 18.5% were prescribed a high potency statin (atorvastatin 80 mg or rosuvastatin 40 mg). The five year incidences of MVE and PVE were 38.1% and 44.7%, respectively. It was estimated that if the mean LDL-C of the cohort had been reduced by 1 mmol/L, this could have reduced the absolute risk of MVE and PVE by 6.5% (95% CI 4.4 - 8.7; NNT 15) and 5.3% (95% CI 1.4 - 7.5; NNT 19), respectively. It was estimated that the maximum allowable expense for a cost effective LDL-C lowering programme would be between $1 239 AUD (€768) and $1 582 AUD (€981) per person per annum over a five year period. CONCLUSION People with a small asymptomatic AAA are at high risk of MVE and PVE. This study provides evidence of the possible benefits and allowable expense for a cost effective intensive LDL-C lowering programme in this population.

Abstract
Advances in several fields of cardiovascular (CV) medicine have produced new treatments (e.g. to treat dyslipidaemia) that have proven efficacy in terms of reducing deaths and providing a better quality of life. However, the burden of CV disease (CVD) remains high. Thus, there is a need to search for new treatment targets. Lipoprotein (a) [Lp(a)] has emerged as a potential novel target since there is evidence that it contributes to CVD events. In this narrative review, we present the current evidence of the potential causal relationship between Lp(a) and CVD and discuss the likely magnitude of Lp(a) lowering required to produce a clinical benefit. We also consider current and investigational treatments targeting Lp(a), along with the potential cost of these interventions.

Abstract
Patients with lower limb artery stenosis or occlusion (peripheral artery disease; PAD) have been determined to be at very high risk of both major adverse cardiovascular events, such as myocardial infarction and stroke, and major adverse limb events, such as amputation and requirement for artery surgery.Effective medical management has been identified as key in reducing this risk; however, this is often poorly implemented in clinical practice. Thus, the aim of this narrative review was to summarize the current evidence on the medical management of PAD in order to inform clinicians and highlight recommendations for clinical practice. International guidelines, randomized controlled trials, and relevant systematic reviews and meta-analyses have been included in this study. The focus was the management of the key modifiable risk factors to mitigate possible adverse events through prescription of anti-platelet and anticoagulation drugs and medications to control low-density lipoprotein cholesterol, blood pressure, and diabetes and aid smoking cessation. The available evidence from randomized clinical trials provide a strong rationale for the need for holistic medical management programs that are effective in achieving uptake of these medical therapies in patients with PAD. In conclusion, people with PAD have some of the highest adverse event rates among those with cardiovascular diseases. Secondary preventive measures have been proven effective in reducing these adverse events; however, they remain to be adequately implemented. Thus, the need for an effective implementation program has emerged to reduce adverse events in this patient group.

Abstract
Critical limb ischemia (CLI) constitutes the most advanced form of peripheral artery disease (PAD) and is characterized by ischemic rest pain, tissue loss and/or gangrene. Optimized medical care and risk factor modification in addition to revascularization could reduce the incidence of cardiovascular events and major adverse limb events, improving patients' quality of life and promising higher survival rates. Adequate adherence to cardioprotective medications, including antithrombotic therapy (e.g., antiplatelets, anticoagulants), cholesterol-lowering agents (e.g., statins, proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors), angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs), and smoking cessation should be strongly encouraged for patients with CLI. This review examines these guideline-recommended therapies in terms of cardiovascular and limb-related risk reduction in patients with CLI.

Abstract
Diabetes-related foot disease (DFD), which includes foot ulcers, infection and gangrene, is a leading cause of the global disability burden. About half of people who develop DFD experience a recurrence within one year. Long-term medical management to reduce the risk of recurrence is therefore important to reduce the global DFD burden. This review describes research assessing the value of sensors, wearables and telehealth in preventing DFD. Sensors and wearables have been developed to monitor foot temperature, plantar pressures, glucose, blood pressure and lipids. The monitoring of these risk factors along with telehealth consultations has promise as a method for remotely managing people who are at risk of DFD. This approach can potentially avoid or reduce the need for face-to-face consultations. Home foot temperature monitoring, continuous glucose monitoring and telehealth consultations are the approaches for which the most highly developed and user-friendly technology has been developed. A number of clinical studies in people at risk of DFD have demonstrated benefits when using one of these remote monitoring methods. Further development and evidence are needed for some of the other approaches, such as home plantar pressure and footwear adherence monitoring. As yet, no composite remote management program incorporating remote monitoring and the management of all the key risk factors for DFD has been developed and implemented. Further research assessing the feasibility and value of combining these remote monitoring approaches as a holistic way of preventing DFD is needed.

Abstract
Background The aim of this study was to assess the relationship between serum lipoprotein (a) (Lp[a]) concentration and the requirement for peripheral artery disease (PAD) operations or incidence of major adverse cardiovascular events. Methods and Results A total of 1472 people with PAD presenting with intermittent claudication (n=355), abdominal aortic aneurysm (n=989) or critical limb ischemia (n=128) were prospectively recruited from 4 outpatient clinics in Australia. Lp(a) was measured in serum samples collected at recruitment using an immunoassay. Participants were followed for a median (interquartile range) of 2.4 (0.1-6.1) years to record requirement for any PAD operation, defined to include any open or endovascular PAD intervention (lower limb peripheral revascularization, abdominal aortic aneurysm repair, other aneurysm repair, or carotid artery revascularization). Myocardial infarctions, strokes, and deaths were also recorded. The association of Lp(a) with events was assessed using Cox proportional hazard analysis adjusting for traditional risk factors. Participants with Lp(a) ≥30 mg/dL had a greater requirement for any PAD operation (hazard ratio, 1.20, 95% CI, 1.02-1.41) and lower limb peripheral revascularization alone (hazard ratio 1.33, 95% CI, 1.06-1.66) but no increased risk of major adverse cardiovascular events or all-cause mortality. Lp(a) ≥50 mg/dL and a 40 mg/dL increase in Lp(a) were also associated with an increased risk of lower limb peripheral revascularization alone but not with other outcomes. Conclusions In participants with PAD referred for hospital management those with high Lp(a) had greater requirement for lower limb peripheral revascularization but Lp(a) was not consistently associated with other clinical events.

Abstract
There is now significant evidence to support an independent causal role for lipoprotein(a) (Lp(a)) as a risk factor for atherosclerotic cardiovascular disease. Plasma Lp(a) concentrations are predominantly determined by genetic factors. However, research into Lp(a) has been hampered by incomplete understanding of its metabolism and proatherogeneic properties and by a lack of suitable animal models. Furthermore, a lack of standardized assays to measure Lp(a) and no universal consensus on optimal plasma levels remain significant obstacles. In addition, there are currently no approved specific therapies that target and lower elevated plasma Lp(a), although there are recent but limited clinical outcome data suggesting benefits of such reduction. Despite this, international guidelines now recognize elevated Lp(a) as a risk enhancing factor for risk reclassification. This review summarises the current literature on Lp(a), including its discovery and recognition as an atherosclerotic cardiovascular disease risk factor, attempts to standardise analytical measurement, interpopulation studies, and emerging therapies for lowering elevated Lp(a) levels.
