Abstract
Peripheral artery disease (PAD) is the narrowing of the arteries that carry blood to the lower extremities. PAD has been traditionally associated with atherosclerosis. However, recent studies have found that medial arterial calcification (MAC) is the primary cause of chronic limb ischemia below the knee. MAC involves calcification of the elastin fibers surrounding smooth muscle cells (SMCs) in arteries. Matrix GLA Protein (MGP) binds circulating calcium and inhibits vascular calcification. Mgp -/- mice develop severe MAC and die within 8 weeks of birth due to aortic rupture or heart failure. We previously discovered a rare genetic disease Arterial Calcification due to Deficiency in CD73 (ACDC) in which patients present with extensive MAC in their lower extremity arteries. Using a patient-specific induced pluripotent stem cell model we found that rapamycin inhibited calcification. Here we investigated whether rapamycin could reduce MAC in vivo using Mgp -/- mice as a model. Mgp +/+ and Mgp -/- mice received 5mg/kg rapamycin or vehicle. Calcification content was assessed via microCT, and vascular morphology and extracellular matrix content assessed histologically. Immunostaining and western blot analysis were used to examine SMC phenotypes and cellular functions. Rapamycin prolonged Mgp -/- mice lifespan, decreased mineral density in the arteries, and increased smooth muscle actin protein levels, however, calcification volume, vessel morphology, SMC proliferation, and autophagy flux were all unchanged. These findings suggest that rapamycin's effects in the Mgp -/- mouse are independent of the vascular phenotype.

Sundaram S, Barksdale C, Rodriguez S, Wooster MD. The Impact Of Small Artery Disease (SAD) and Medial Arterial Calcification (MAC) Scores on Chronic Wound and Amputation Healing: Can It Tell Us More? Ann Vasc Surg 2024:S0890-5096(24)00479-5. [PMID: 39059628 DOI: 10.1016/j.avsg.2024.07.089] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2024] [Revised: 06/19/2024] [Accepted: 07/01/2024] [Indexed: 07/28/2024]
Abstract
Plenary Session Presentation at the Vascular and Endovascular Surgical Society 28th Annual Winter Meeting; Sun Valley Resort, Sun Valley, ID January 18 - 21, 2024 OBJECTIVES: In 2021, Ferraresi et al. created a novel scoring system based on the impact of small artery disease (SAD) and medial arterial calcification (MAC) on wound healing. SAD and MAC scores functioned similar to WIfI but with minimal resource expenditure. Despite its potential, few studies have expanded on the original dataset. We aim to validate SAD and MAC's impact on wound healing outcomes and determine their utility in relation to current predictive models. METHODS Single-institution retrospective review was used to identify amputations for chronic (>1mo) podiatric wounds between 2015-2020. Foot x-ray (MAC) or angiography (SAD) <6 months of index procedure was required. Primary outcomes included major amputation, wound healing, major adverse limb events (MALE), and amputation-free survival (AFS). Statistical analysis included chi-square, one-way ANOVA, non-parametric correlation, Kaplan-Meier, Cox regression, and Akaike (AIC)/ Bayesian Inclusion Criteria (BIC) model comparison. RESULTS Of 136 limbs, 67 received SAD scores (0-2) and 128 received MAC scores (0-2). SAD cohorts exhibited similar comorbidity profiles with exception of coronary disease, heart failure, and chronic kidney disease. MAC cohorts were notably disparate in prevalence of multiple conditions. High mean SAD/MAC scores were seen in severe (3-vessel) below-ankle disease (p=.001* [SAD], p=.041* [MAC]). Both SAD and MAC correlated with lower mean toe pressure (p=.043* [SAD], p=<.001* [MAC]), while only MAC correlated with higher overall WIfI score (p=.029*). No significant procedural differences were noted. However, higher re-admission rates (73.9% [2] vs. 46.9% [0], p=.014*) and all-cause mortality (65.2% [2] vs. 26.0% [0], p=.002*) were noted with higher MAC. Survival analysis revealed higher one-year major amputation rates (p=.036*), impaired wound healing (p<.001*), and lower amputation-free survival (p=.001*) with increasing MAC severity. Additionally, MAC-2 patients underwent amputation at faster rates than MAC-0 patients (HR 5.25, 95% CI [1.82, 9.77]) with longer times to wound healing (HR 0.21, 95% CI [0.08, 0.53]). Model comparison suggested a combination of WIfI and MAC could improve accuracy of predicted time to major amputation, wound healing, and amputation-free survival. CONCLUSIONS MAC scoring showed significant promise both as individual predictor and adjunct to current predictive models of long-term wound healing outcomes. Routine use of MAC scoring in CLTI evaluation, especially when non-invasive testing is unavailable, could promote timely referral for intervention and efficient resource utilization in limited-resource or critical care settings. Further investigation is necessary to determine MAC's impact on revascularization and how scoring can be used to guide surgical decision making.

J Vasc Surg 2024; 80:188-198.e1. [PMID: 38301808 DOI: 10.1016/j.jvs.2024.01.205] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2023] [Revised: 01/22/2024] [Accepted: 01/25/2024] [Indexed: 02/03/2024]
Abstract
OBJECTIVE The aim of this study was to investigate whether intimal arterial calcification (IAC) and medial arterial calcification (MAC) are correlated with the various clinical outcomes following endovascular therapy (EVT) for peripheral arterial disease (PAD). METHODS This single-center retrospective study comprised 154 consecutively hospitalized individuals with PAD who underwent EVT for de novo femoral-popliteal calcific lesions from January 2016 to July 2021. The predominant calcification patterns of IAC and MAC were assessed using a semi-quantitative computed tomography scoring system. The Kaplan-Meier method and Cox regression were conducted to evaluate the correlations between calcification patterns and medium- to long-term outcomes. RESULTS The distribution of calcification patterns was as follows: IAC in 111 patients (72%) and MAC in 43 patients (28%). No remarkable variation was noted between the IAC and MAC groups regarding age (P = .84) and gender (P = .23). The MAC group indicated lower rates of 4-year primary patency, assisted primary patency, secondary patency, and amputation-free survival (AFS) compared with the IAC group (24% ± 7% vs 40% ± 6%; P = .003; 30% ± 8% vs 51% ± 6%; P = .001; 51% ± 8% vs 65% ± 5%; P = .004; and 43% ± 9% vs 76% ± 5%; P < .001, respectively). There was no significant difference in the rate of freedom from clinically driven target lesion revascularization between the MAC and IAC groups (63% ± 10% vs 73% ± 5%; P = .26). Stepwise multivariable Cox regression analysis demonstrated that MAC was associated with poor patency (hazard ratio, 1.81; 95% confidence interval, 1.12-2.93; P = .016) and AFS (hazard ratio, 2.80; 95% confidence interval, 1.52-5.16; P = .001). CONCLUSIONS Compared with IAC, MAC is independently associated with lower medium- to long-term patency and AFS after EVT for de novo femoral-popliteal occlusive lesions.

Abstract
INTRODUCTION Hypertension can accelerate and aggravate the process of arterial ageing and calcification. However, the mechanism behind has yet to be well elucidated. METHODS Here, we monitored the dynamic changes of fibronectin (FN)/α5 integrin, bone morphogenetic protein 2/matrix Gla protein (BMP2/MGP), and Runx2 in the aorta of spontaneously hypertensive rats (SHRs) and thoracic aortic vascular smooth muscle cells (VSMCs), also the phenotypic transformation of VSMCs during the process of arterial ageing and calcification. Further, study on arterial ageing and calcification through antagonist experiments at the molecular level was explored. RESULTS We found extracellular FN and its α5 integrin receptor expressions were positively associated with arterial ageing and calcification in SHR during ageing, as well in VSMCs from SHR in vitro. Integrin receptor inhibitor of GRGDSP would delay this arterial ageing and calcification process. Moreover, the elevated FN and α5 integrin receptor expression evoked the disequilibrium of BMP2/MGP, where the expression of BMP2, a potent osteogenic inducer, increased while MGP, a calcification inhibitor, decreased. Furthermore, it was followed by the upregulation of Runx2 and the phenotypic transformation of VSMCs from the contractile phenotype into the osteoblast-like cells. Notably, BMP2 antagonist of rmNoggin was sufficient to ameliorate the ageing and calcification process of VSMCs and exogenous BMP2-adding accelerate and aggregate the process. CONCLUSION Our study revealed that hypertension-associated arterial ageing and calcification might be a consequence that hypertension up-regulated FN and its high binding affinity integrin α5 receptor in the aortic wall, which in turn aggravated the imbalance of BMP2/MGP, promoted the transcription of Runx2, and induced the phenotypic transformation of VSMCs from the contractile phenotype into the osteoblast-like cells. Our study would provide insights into hypertension-associated arterial ageing and calcification and shed new light on the control of arterial calcification, especially for those with hypertension.

Abstract
BACKGROUND Arterial calcification due to deficiency of CD73 (ACDC; OMIM 211800) is a rare genetic disease resulting in calcium deposits in arteries and small joints causing claudication, resting pain, severe joint pain, and deformities. Currently, there are no standard treatments for ACDC. Our previous work identified etidronate as a potential targeted ACDC treatment, using in vitro and in vivo disease models with patient-derived cells. In this study, we test the safety and effectiveness of etidronate in attenuating the progression of lower-extremity arterial calcification and vascular blood flow based on the computed tomography (CT) calcium score and ankle-brachial index (ABI). METHODS Seven adult patients with a confirmed genetic diagnosis of ACDC were enrolled in an open-label, nonrandomized, single-arm pilot study for etidronate treatment. They took etidronate daily for 14 days every 3 months and were examined at the NIH Clinical Center bi-annually for 3 years. They received a baseline evaluation as well as yearly follow up after treatment. Study visits included imaging studies, exercise tolerance tests with ABIs, clinical blood and urine testing, and full dental exams. RESULTS Etidronate treatment appeared to have slowed the progression of further vascular calcification in lower extremities as measured by CT but did not have an effect in reversing vascular and/or periarticular joint calcifications in our small ACDC cohort. CONCLUSIONS Etidronate was found to be safe and well tolerated by our patients and, despite the small sample size, appeared to show an effect in slowing the progression of calcification in our ACDC patient cohort.(ClinicalTrials.gov Identifier NCT01585402).

Abstract
The femoropopliteal artery (FPA) is the main artery in the lower limb. It supplies blood to the leg muscles and undergoes complex deformations during limb flexion. Atherosclerotic disease of the FPA (peripheral arterial disease, PAD) is a major public health burden, and despite advances in surgical and interventional therapies, the clinical outcomes of PAD repairs continue to be suboptimal, particularly in challenging calcified lesions and biomechanically active locations. A better understanding of human FPA mechanical and structural characteristics in relation to age, risk factors, and the severity of vascular disease can help develop more effective and longer-lasting treatments through computational modeling and device optimization. This review aims to summarize recent research on the main biomechanical and structural properties of human superficial femoral and popliteal arteries that comprise the FPA and describe their anatomy, composition, and mechanical behavior under different conditions.

Abstract
AIMS Pedal medial arterial calcification (MAC) is frequently observed in individuals with diabetic foot ulcers (DFUs). However, the impact of pedal MAC on individuals with DFUs remains uncertain. The main aim of this study was to evaluate the association between pedal MAC with amputation and mortality outcomes. METHODS A prospective, observational cohort study was conducted at West China Hospital from January 2012 to December 2021. Logistic regression analyses, Kaplan-Meier survival method, and Cox proportional hazards models were employed to evaluate the relationship between pedal MAC and amputation as well as mortality. RESULTS A total of 979 patients were enrolled in the study. Peripheral artery disease (PAD) was observed in 53% of patients with DFUs, and pedal MAC was found in 8%. Over a median follow-up of 46 (23-72) months, foot amputation was performed on 190 patients, and mortality occurred in 246 patients. Pedal MAC showed a significant association with amputation both in unadjusted analysis (odds ratio [OR] = 2.98, 95% confidence interval [CI] = 1.86-4.76, p < .001) and after adjusting sex, age, albumin levels, hemoglobin levels, and diabetic retinopathy status (OR 2.29, 95% CI 1.33-3.93, p = .003). The risk of amputation was found to be twofold higher in individuals with PAD and pedal MAC compared to those with PAD alone (OR 2.05, 95% CI 1.10-3.82, p = .024). Furthermore, the presence of pedal MAC was significantly associated with an increased risk of mortality (p = .005), particularly among individuals with DFUs but without PAD (HR 4.26, 95% CI 1.90-9.52, p < .001), rather than in individuals presenting with both DFUs and PAD. CONCLUSION The presence of pedal MAC is significantly associated with both amputation and mortality in individuals with DFUs. Moreover, pedal MAC could provide additional value to predict amputation other than PAD.

Abstract
Peripheral Artery Disease (PAD) affects the lower extremities and frequently results in poor clinical outcomes, especially in the vessels below the knee. Understanding the biomechanical and structural characteristics of these arteries is important for improving treatment efficacy, but mechanical and structural data on tibial vessels remain limited. We compared the superficial femoral (SFA) and popliteal (PA) arteries that comprise the above-knee femoropopliteal (FPA) segment to the infrapopliteal (IPA) anterior tibial (AT), posterior tibial (PT), and fibular (FA) arteries from the same 15 human subjects (average age 52, range 42-67 years, 87 % male). Vessels were imaged using μCT, evaluated with biaxial mechanical testing and constitutive modeling, and assessed for elastin, collagen, smooth muscle cells (SMCs), and glycosaminoglycans (GAGs). IPAs were more often diseased or calcified compared to the FPAs. They were also twice smaller, 53 % thinner, and significantly stiffer than the FPA longitudinally, but not circumferentially. IPAs experienced 48 % higher physiologic longitudinal stresses (62 kPa) but 27 % lower circumferential stresses (24 kPa) and similar cardiac cycle stretch of <1.02 compared to the FPA. IPAs had lower longitudinal pre-stretch (1.12) than the FPAs (1.29), but there were no differences in the stored elastic energy during pulsation. The physiologic circumferential stiffness was similar in the above and below-knee arteries (718 kPa vs 754 kPa). Structurally, IPAs had less elastin, collagen, and GAGs than the FPA, but maintained similar SMC content. Our findings contribute to a better understanding of segment-specific human lower extremity artery biomechanics and may inform the development of better medical devices for PAD treatment. STATEMENT OF SIGNIFICANCE: Peripheral Artery Disease (PAD) in the lower extremity arteries exhibits distinct characteristics and results in different clinical outcomes when treating arteries above and below the knee. However, their mechanical, structural, and physiologic differences are poorly understood. Our study compared above- and below-knee arteries from the same middle-aged human subjects and demonstrated distinct differences in size, structure, and mechanical properties, leading to variations in their physiological behavior. These insights could pave the way for creating location-specific medical devices and treatments for PAD, offering a more effective approach to its management. Our findings provide new, important perspectives for clinicians, researchers, and medical device developers interested in treating PAD in both above- and below-knee locations.

Abstract
Hyperphosphatemia is a common feature in patients with impaired kidney function and is associated with increased risk of cardiovascular disease. This phenomenon extends to the general population, whereby elevations of serum phosphate within the normal range increase risk; however, the mechanism by which this occurs is multifaceted, and many aspects are poorly understood. Less than 1% of total body phosphate is found in the circulation and extracellular space, and its regulation involves multiple organ cross talk and hormones to coordinate absorption from the small intestine and excretion by the kidneys. For phosphate to be regulated, it must be sensed. While mostly enigmatic, various phosphate sensors have been elucidated in recent years. Phosphate in the circulation can be buffered, either through regulated exchange between extracellular and cellular spaces or through chelation by circulating proteins (ie, fetuin-A) to form calciprotein particles, which in themselves serve a function for bulk mineral transport and signaling. Either through direct signaling or through mediators like hormones, calciprotein particles, or calcifying extracellular vesicles, phosphate can induce various cardiovascular disease pathologies: most notably, ectopic cardiovascular calcification but also left ventricular hypertrophy, as well as bone and kidney diseases, which then propagate phosphate dysregulation further. Therapies targeting phosphate have mostly focused on intestinal binding, of which appreciation and understanding of paracellular transport has greatly advanced the field. However, pharmacotherapies that target cardiovascular consequences of phosphate directly, such as vascular calcification, are still an area of great unmet medical need.

Abstract
Background Vascular calcification (VC) commonly occurs and seriously increases the risk of cardiovascular events and mortality in patients with hemodialysis. For optimizing individual management, we will develop a diagnostic multivariable prediction model for evaluating the probability of VC. Methods The study was conducted in four steps. First, identification of miRNAs regulating osteogenic differentiation of vascular smooth muscle cells (VSMCs) in calcified condition. Second, observing the role of miR-129-3p on VC in vitro and the association between circulating miR-129-3p and VC in hemodialysis patients. Third, collecting all indicators related to VC as candidate variables, screening predictors from the candidate variables by Lasso regression, developing the prediction model by logistic regression and showing it as a nomogram in training cohort. Last, verifying predictive performance of the model in validation cohort. Results In cell experiments, miR-129-3p was found to attenuate vascular calcification, and in human, serum miR-129-3p exhibited a negative correlation with vascular calcification, suggesting that miR-129-3p could be one of the candidate predictor variables. Regression analysis demonstrated that miR-129-3p, age, dialysis duration and smoking were valid factors to establish the prediction model and nomogram for VC. The area under receiver operating characteristic curve of the model was 0.8698. The calibration curve showed that predicted probability of the model was in good agreement with actual probability and decision curve analysis indicated better net benefit of the model. Furthermore, internal validation through bootstrap process and external validation by another independent cohort confirmed the stability of the model. Conclusion We build a diagnostic prediction model and present it as an intuitive tool based on miR-129-3p and clinical indicators to evaluate the probability of VC in hemodialysis patients, facilitating risk stratification and effective decision, which may be of great importance for reducing the risk of serious cardiovascular events.

Abstract
Chronic wounds, especially diabetic ulcers, pose a significant challenge in regenerative medicine. Cellulose derivatives offer remarkable wound management properties, such as effective absorption and retention of wound exudates, maintaining an optimal moisture environment crucial for successful chronic wound regeneration. However, conventional dressings have limited efficacy in managing and healing these types of skin lesions, driving scientists to explore innovative approaches. The emergence of 3D printing has enabled personalized dressings that meet individual patient needs, improving the healing process and patient comfort. Cellulose derivatives meet the demanding requirements for biocompatibility, printability, and biofabrication necessary for 3D printing of biologically active scaffolds. However, the potential applications of nanocellulose and cellulose derivative-based inks for wound regeneration remain largely unexplored. Thus, this review provides a comprehensive overview of recent advancements in cellulose-based inks for 3D printing of personalized wound dressings. The composition and biofabrication approaches of cellulose-based wound dressings are thoroughly discussed, including the functionalization with bioactive molecules and antibiotics for improved wound regeneration. Similarly, the in vitro and in vivo performance of these dressings is extensively examined. In summary, this review aims to highlight the exceptional advantages and diverse applications of 3D printed cellulose-based dressings in personalized wound care.

Abstract
INTRODUCTION Peripheral arterial disease (PAD) is a progressive vascular condition characterized by the narrowing or blockage of arteries, primarily attributed to atherosclerosis. PAD's prevalence in the general population is estimated at approximately 5.9%. Notably however, among patients with chronic kidney disease (CKD), PAD's prevalence is substantially higher, ranging from 17% to 48%. This review paper emphasizes the pervasiveness of PAD and its intricate relationship with CKD and end-stage renal disease (ESRD). It demonstrates the importance of early detection, proactive screening, and understanding the formidable challenges associated with treating heavily calcified lesions. EVIDENCE ACQUISITION Comprehensive literature searches encompassed the PubMed/MEDLINE, Cochrane Library, and Embase databases, in order to identify studies involving lower extremity peripheral arterial interventions in patients both with and without CKD or ESRD. The search spanned the timeframe from January 2001 to July 2023. The search strategy included vocabulary terms concerning peripheral artery disease, lower extremities, revascularization, chronic kidney disease, and end-stage renal disease. EVIDENCE SYNTHESIS Initial searches were used to identify articles based on title. Exclusion criteria was then applied, and any redundant articles were removed. The articles abstracts were then reviewed, and relevant articles were selected. Once selected the articles were thoroughly reviewed including the references to find other relevant articles that were missed during the initial search process. In total 28 articles were selected and included for review of clinical data in regard to PAD outcomes in patients with advanced kidney disease. CONCLUSIONS The findings highlight the need for personalized approaches in diagnosing and treating PAD in CKD and ESRD patients. Interdisciplinary collaboration, such as those between nephrologists, vascular surgeons, and interventional radiologists, is vital to optimize outcomes. Further research should focus on innovative, tailored interventions to enhance limb preservation, reduce mortality, prolong patency, and cut healthcare costs.

Abstract
BACKGROUND Medial arterial calcification (MAC) is a vascular disease distinct from atherosclerosis. Recently, several studies have demonstrated that MAC is an important marker of cardiovascular events. We aim to assess the presence of MAC during ultrasound screening of lower-limb vasculature and its association with both cardiovascular (CV) and lower-limb events in patients with type-2 diabetes. METHODS A retrospective cohort study was conducted on 1119 patients with type-2 diabetes free from CV disease. A CV work-up, including vascular ultrasound, was performed for each patient. The presence of MAC was assessed on posterior tibial arteries and ankle-brachial index (ABI) was measured. Major acute CV events (MACEs) and lower-limb events (MALEs) were recorded as a composite endpoint for a 5-year period. RESULTS We identified MAC among 212 (18.9%) patients. The independent determinants of MAC were age and diabetic retinopathy. Over a period of 5 years, 125 MACEs and 22 MALEs occurred. MAC was significantly associated with the composite outcome MACE + MALE (HR = 1.94; 95% CI: 1.23, 3.08, p = 0.005) or with MACE (HR = 1.85; 95% CI: 1.16, 2.95, p = 0.010). Adjusted for ABI and diabetic foot wound, MAC remained a determinant of MALE (HR = 5.49; 95% CI: 2.19, 13.76, p < 0.001). Considering each ABI group, MAC was associated with both MACE and MALE in the normal ABI group. CONCLUSIONS Ultrasound-detected MAC on tibial arteries seems to be a determinant of both CV and lower-limb events, independent from ABI. MAC helps to refine the CV risk in patients with normal ABI.

Abstract
Vascular aging, i.e., the deterioration of the structure and function of the arteries over the life course, predicts cardiovascular events and mortality. Vascular degeneration can be recognized before becoming clinically symptomatic; therefore, its assessment allows the early identification of individuals at risk. This opens the possibility of minimizing disease progression. To review these issues, a search was completed using PubMed, MEDLINE, and Google Scholar from 2000 to date. As a network of clinicians and scientists involved in vascular medicine, we here describe the structural and functional age-dependent alterations of the arteries, the clinical tools for an early diagnosis of vascular aging, and the cellular and molecular events implicated. It emerges that more studies are necessary to identify the best strategy to quantify vascular aging, and to design proper physical activity programs, nutritional and pharmacological strategies, as well as social interventions to prevent, delay, and eventually revert the disease.

Abstract
Vascular calcification is the abnormal deposition of calcium phosphate complexes in blood vessels, which is regarded as the pathological basis of multiple cardiovascular diseases. The flowing blood exerts a frictional force called shear stress on the vascular wall. Blood vessels have different hydrodynamic properties due to discrepancies in geometric and mechanical properties. The disturbance of the blood flow in the bending area and the branch point of the arterial tree produces a shear stress lower than the physiological magnitude of the laminar shear stress, which can induce the occurrence of vascular calcification. Endothelial cells sense the fluid dynamics of blood and transmit electrical and chemical signals to the full-thickness of blood vessels. Through crosstalk with endothelial cells, smooth muscle cells trigger osteogenic transformation, involved in mediating vascular intima and media calcification. In addition, based on the detection of fluid dynamics parameters, emerging imaging technologies such as 4D Flow MRI and computational fluid dynamics have greatly improved the early diagnosis ability of cardiovascular diseases, showing extremely high clinical application prospects.

Abstract
A 48-year-old man with long-standing type 2 diabetes mellitus (recent glycated hemoglobin level, 6.5%) and chronic kidney disease (baseline creatinine level, 3.3 mg per deciliter [292 μ mol per liter]; glomerular filtration rate, 24 ml per minute per 1.73 m2 of body-surface area) presented to his primary care physician with a 3-month history of numbness, tingling, and faint violaceous discoloration of the tips of multiple fingers and toes. His physical examination showed reduced light-touch sensation in a glove-and-stocking distribution; the radial and pedal pulses were palpable. The vitamin B12 level was 260 pg per milliliter (192 pmol per liter; normal range, 190 to 950 pg per milliliter [140 to 701 pmol per liter]). He did not smoke tobacco, drink alcohol, or use illicit drugs. One month later, a nontraumatic wound developed on the left foot. The ankle–brachial index (ABI) was 1.2 on both sides (normal range, 0.91 to 1.3). Wound care was initiated for a presumed neuropathic ulcer.

Myoglobinemia, Peripheral Arterial Disease, and Patient Mortality. J Am Coll Surg 2023; 236:588-598. [PMID: 36656266 PMCID: PMC10010700 DOI: 10.1097/xcs.0000000000000554] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2022] [Accepted: 12/13/2022] [Indexed: 01/20/2023]
Abstract
BACKGROUND Peripheral arterial disease (PAD) causes leg muscle damage due to inadequate perfusion and increases cardiovascular events and mortality 2- to 3-fold. It is unclear if PAD is a biomarker for high-risk cardiovascular disease or if skeletal muscle injury harms arterial health. The objective of this work is to test if serum myoglobin levels (myoglobinemia) are a marker of PAD, and if so, whether myoglobin impairs vascular health. STUDY DESIGN Patient blood samples were collected from PAD and control (no PAD) patients and interrogated for myoglobin concentrations and nitric oxide bioavailability. Patient mortality over time was captured from the medical record. Myoglobin activity was tested on endothelial cells and arterial function. RESULTS Myoglobin is a biomarker for symptomatic PAD and was inversely related to nitric oxide bioavailability; 200 ng/mL myoglobin in vitro increased endothelial cell permeability in vitro and decreased nitrate bioavailability. Ex vivo, 100 ng/mL myoglobin increased vascular tone in naive murine aortas approximately 1.5 times, impairing absolute vessel relaxation. In vivo, we demonstrated that myoglobinemia caused impaired flow-mediated dilation in a porcine model. Patients presenting with myoglobin levels of 100 ng/mL or greater had significantly more deaths than those with myoglobin levels of less than 100 ng/mL. CONCLUSIONS Using a combination of patient data, in vitro, ex vivo, and in vivo testing, we found that myoglobin is a biomarker for symptomatic PAD and a potent regulator of arterial health that can increase vascular tone, increase vascular permeability, and cause endothelial dysfunction, all of which may contribute to the vulnerability of PAD patients to cardiovascular events and death.

Abstract
Atherosclerosis is a chronic inflammatory disease characterized by the accumulation of lipids in the vessel wall, leading to the formation of an atheroma and eventually to the development of vascular calcification (VC). Lipoproteins play a central role in the development of atherosclerosis and VC. Both low- and very low-density lipoproteins (LDL and VLDL) and lipoprotein (a) (Lp(a)) stimulate, while high-density lipoproteins (HDL) reduce VC. Apolipoproteins, the protein component of lipoproteins, influence the development of VC in multiple ways. Apolipoprotein AI (apoAI), the main protein component of HDL, has anti-calcific properties, while apoB and apoCIII, the main protein components of LDL and VLDL, respectively, promote VC. The role of lipoproteins in VC is also related to their metabolism and modifications. Oxidized LDL (OxLDL) are more pro-calcific than native LDL. Oxidation also converts HDL from anti- to pro-calcific. Additionally, enzymes such as autotaxin (ATX) and proprotein convertase subtilisin/kexin type 9 (PCSK9), involved in lipoprotein metabolism, have a stimulatory role in VC. In summary, a better understanding of the mechanisms by which lipoproteins and apolipoproteins contribute to VC will be crucial in the development of effective preventive and therapeutic strategies for VC and its associated cardiovascular disease.

Abstract
Cardiovascular disease is the most common cause of death worldwide, especially beyond the age of 65 years, with the vast majority of morbidity and mortality due to myocardial infarction and stroke. Vascular pathology stems from a combination of genetic risk, environmental factors, and the biologic changes associated with aging. The pathogenesis underlying the development of vascular aging, and vascular calcification with aging, in particular, is still not fully understood. Accumulating data suggests that genetic risk, likely compounded by epigenetic modifications, environmental factors, including diabetes and chronic kidney disease, and the plasticity of vascular smooth muscle cells to acquire an osteogenic phenotype are major determinants of age-associated vascular calcification. Understanding the molecular mechanisms underlying genetic and modifiable risk factors in regulating age-associated vascular pathology may inspire strategies to promote healthy vascular aging. This article summarizes current knowledge of concepts and mechanisms of age-associated vascular disease, with an emphasis on vascular calcification.

Pro-Calcific Environment Impairs Ischaemia-Driven Angiogenesis. Int J Mol Sci 2022; 23:ijms23063363.

Abstract
Peripheral arterial disease (PAD) is characterised by accelerated arterial calcification and impairment in angiogenesis. Studies implicate vascular calcification as a contributor to PAD, but the mechanisms remain unclear. We aimed to determine the effect of calcification on ischaemia-driven angiogenesis. Human coronary artery endothelial cells (ECs) were treated with calcification medium (CM: CaCl2 2.7 mM, Na2PO4 2.0 mM) for 24 h and exposed to normoxia (5% CO2) or hypoxia (1.2% O2; 5% CO2 balanced with N2). In normoxia, CM significantly inhibited tubule formation and migration and upregulated calcification markers of ALP, BMP2, and Runx2. CM elevated levels of calcification-protective gene OPG, demonstrating a compensatory mechanism by ECs. CM failed to induce pro-angiogenic regulators VEGFA and HIF-1α in hypoxia and further suppressed the phosphorylation of endothelial nitric oxide synthase (eNOS) that is essential for vascular function. In vivo, osteoprotegerin-deficient mice (OPG−/−), a calcification model, were subjected to hind-limb ischaemia (HLI) surgery. OPG−/− mice displayed elevated serum alkaline phosphatase (ALP) activity compared to wild-type controls. OPG−/− mice experienced striking reductions in blood-flow reperfusion in both 8-week-old and 6-month-old mice post-HLI. This coincided with significant impairment in tissue ischaemia and reduced limb function as assessed by clinical scoring (Tarlov). This study demonstrated for the first time that a pro-calcific environment is detrimental to ischaemia-driven angiogenesis. The degree of calcification in patients with PAD can often be a limiting factor with the use of standard therapies. These highly novel findings require further studies for full elucidation of the mechanisms involved and have implications for the development of therapies to suppress calcification in PAD.

Abstract
There is a growing interest in arterial and heart valve calcifications, as these contribute to cardiovascular outcome, and are leading predictors of cardiovascular and kidney diseases. Cardiovascular calcifications are often considered as one disease, but, in effect, they represent multifaced disorders, occurring in different milieus and biological phenotypes, following different pathways. Herein, we explore each different molecular process, its relative link with the specific clinical condition, and the current therapeutic approaches to counteract calcifications. Thus, first, we explore the peculiarities between vascular and valvular calcium deposition, as this occurs in different tissues, responds differently to shear stress, has specific etiology and time courses to calcification. Then, we differentiate the mechanisms and pathways leading to hyperphosphatemic calcification, typical of the media layer of the vessel and mainly related to chronic kidney diseases, to those of inflammation, typical of the intima vascular calcification, which predominantly occur in atherosclerotic vascular diseases. Finally, we examine calcifications secondary to rheumatic valve disease or other bacterial lesions and those occurring in autoimmune diseases. The underlying clinical conditions of each of the biological calcification phenotypes and the specific opportunities of therapeutic intervention are also considered and discussed.
