RESUMEN

INTRODUCTION: It is well known that peripheral artery disease (PAD) and coronary artery disease (CAD) coexist and therefore, patients diagnosed with PAD have an increased chance of developing concomitant CAD. CAD-related complications could be a leading cause of postoperative mortality in individuals with PAD undergoing vascular surgery. We present a case series of 48 patients who underwent coronary angiography before vascular surgery and an updated review of previous reports to determine the prevalence of concomitant CAD in a convenience sample of Iranian patients. METHODS: This cross-sectional study was performed on 48 patients with confirmed PAD admitted to Imam Ali Hospital, affiliated with the Kermanshah University of Medical Sciences (KUMS), Kermanshah Province, Iran. A vascular surgeon diagnosed PAD based on the patient's symptoms, Doppler ultrasound, and CT angiography (CTA). All patients underwent coronary angiography to determine if they also had CAD. We defined significant CAD as a ≥70% luminal diameter narrowing of a major epicardial artery or a ≥50% narrowing of the left main coronary artery. RESULTS: Of 48 patients, 35 (72.9%) were male, 13 (27.1%) were female, and the mean age was 64.18±12.11 years (range, 30 to 100 years). The incidence of CAD in patients with PVD was 85.42% (41/48). The patients with CAD were more likely to be hypertensive than those without CAD (80.5 vs. 14.3, p-value<0.001). Of 41 patients with CAD, 9 (22.0%) had one-vessel disease, 10 (24.3%) had two-vessel disease, and 22 (53.7%) had three-vessel disease. CONCLUSION: Hypertension was a significant risk factor for CAD. Patients with hypertension and multiple major coronary risk factors scheduled for PVD surgery should be carefully evaluated for concomitant CAD.

RESUMEN

BACKGROUND: Although red meat consumption has been associated with risk of atherosclerotic coronary artery disease and stroke, no prospective study has examined this with the risk of chronic limb-threatening ischemia (CLTI). METHODS: In a prospective study of 63,257 Chinese in Singapore, who were aged 45-74 years old at recruitment, diet was assessed via a validated semi-quantitative food frequency questionnaire. Incident CLTI cases were ascertained via linkage with nationwide hospital records for lower extremity amputation or angioplasty for peripheral arterial disease. Multivariable Cox models were used to examine associations between quartiles of meat intake and CLTI risk. RESULTS: After a mean follow-up of 18.8 years, there were 1069 cases of CLTI. Higher intake of red meat intake was associated with increased risk of CLTI in a stepwise manner. Comparing extreme quartiles of red meat intake, the hazard ratio (HR) for the association with CLTI risk was 1.24 [95% confidence interval (CI) = 1.03-1.49; P-trend = 0.02]. In stratified analysis, red meat intake had a stronger association with CLTI risk among those without diabetes [HR (95% CI) comparing extreme quartiles = 1.41 (1.10-1.80); P-trend = 0.03] than among those with diabetes at baseline [HR (95% CI) comparing extreme quartiles = 1.04 (0.79-1.38); P-trend = 0.05] (P-interaction = 0.03). Otherwise, the associations were not different by sex, BMI, smoking status, hypertension, alcohol consumption, or history of cardiovascular diseases. Using a theoretical model in substitution analysis that substituted three servings per week of red meat with poultry or fish/shellfish, the relative risk of CLTI was reduced by 13-14%. CONCLUSIONS: Consumption of red meat was associated with higher CLTI risk in this Asian cohort. Substituting red meat with poultry or fish/shellfish may reduce this risk.

RESUMEN

Objective: This study explored the utility of NLR (neutrophil-to-lymphocyte ratio) as a marker to predict Lower Extremity Peripheral Artery Disease (PAD) in the Chinese population, as well as to assess its consistency and diagnostic value with digital subtraction angiography. Methods: Patients were distributed into three groups according to the angiography in lower limb arterial: group L1, plaque with no stenosis; group L2, plaque with luminal stenosis and group L3, total vascular occlusion. Changes in the neutrophil-to-lymphocyte ratio were documented and compared among groups. Results: Compared to group L1, NLR was significantly increased in L2 (1.76 vs 2.35, p=0.037) and L3 (1.76 vs 3.60, p<0.001), with a gradual decrease in ABI (Ankle-Brachial Index, 1.11 vs 1.02 vs 0.94, p<0.001). Those older patients with higher prevalence of hypertension (p=0.002), obesity (p=0.032), or reduced high-density lipoprotein cholesterol (p=0.020) were more likely to develop PAD; higher glycosylated hemoglobin (p=0.045), low-density lipoprotein cholesterol (p=0.006), and systolic blood pressure (p<0.001) levels led to a greater tendency to suffer stenosis or even occlusion; the probability of severe stenosis (>70%) increased to 2.075 times for every 1 increase in NLR, while it was 46.8% for every 0.1 increase in ABI. The optimal NLR cut-off value to predict severe stenosis in PAD was 2.73. Receiver operating characteristic curve analysis of the inflammatory biomarkers and severe stenosis prediction displayed an area under the curve of 0.81. Conclusion: NLR could serve as a new noninvasive and accurate marker in predicting PAD.

RESUMEN

BACKGROUND: The potential preventive effect of fenofibrate on lower extremity amputation (LEA) and peripheral arterial disease (PAD) in patients with type 2 diabetes (T2D) is not fully elucidated. METHODS: We selected adult patients ≥ 20 years of age with T2D from the Korean National Health Insurance Service Database (2009-2012). The fenofibrate users were matched in a 1:4 ratio with non-users using propensity scores (PS). The outcome variables were a composite of LEA and PAD and the individual components. The risks of outcomes were implemented as hazard ratio (HR) with 95% confidence intervals (CI). For safety issues, the risks of acute kidney injury, rhabdomyolysis and resulting hospitalization were analyzed. RESULTS: A total of 114,920 patients was included in the analysis with a median follow-up duration of 7.6 years (22,984 and 91,936 patients for the fenofibrate user and non-user groups, respectively). After PS matching, both groups were well balanced. The fenofibrate group was associated with significantly lower risks of composite outcome of LEA and PAD (HR 0.81; 95% CI 0.70-0.94), LEA (HR 0.76; 95% CI 0.60-0.96), and PAD (HR 0.81; 95% CI 0.68-0.96). The risk of acute kidney injury, rhabdomyolysis, or hospitalization for these events showed no significant difference between the two groups. Subgroup analyses revealed consistent benefits across age groups, genders, and baseline lipid profiles. CONCLUSIONS: This nationwide population-based retrospective observational study suggests that fenofibrate can prevent LEA and PAD in patients with T2D who are on statin therapy.

RESUMEN

Platelets are key mediators of atherothrombosis, yet, limited tools exist to identify individuals with a hyperreactive platelet phenotype. In this study, we investigate the association of platelet hyperreactivity and cardiovascular events, and introduce a tool, the Platelet Reactivity ExpreSsion Score (PRESS), which integrates platelet aggregation responses and RNA sequencing. Among patients with peripheral artery disease (PAD), those with a hyperreactive platelet response (>60% aggregation) to 0.4 µM epinephrine had a higher incidence of the 30 day primary cardiovascular endpoint (37.2% vs. 15.3% in those without hyperreactivity, adjusted HR 2.76, 95% CI 1.5-5.1, p = 0.002). PRESS performs well in identifying a hyperreactive phenotype in patients with PAD (AUC [cross-validation] 0.81, 95% CI 0.68 -0.94, n = 84) and in an independent cohort of healthy participants (AUC [validation] 0.77, 95% CI 0.75 -0.79, n = 35). Following multivariable adjustment, PAD individuals with a PRESS score above the median are at higher risk for a future cardiovascular event (adjusted HR 1.90, CI 1.07-3.36; p = 0.027, n = 129, NCT02106429). This study derives and validates the ability of PRESS to discriminate platelet hyperreactivity and identify those at increased cardiovascular risk. Future studies in a larger independent cohort are warranted for further validation. The development of a platelet reactivity expression score opens the possibility for a personalized approach to antithrombotic therapy for cardiovascular risk reduction.

RESUMEN

ABSTRACT: The dual pathway inhibition (DPI) with low-dose rivaroxaban and aspirin in patients with stable atherosclerotic vascular disease reduces the occurrence of cardiovascular events, with no significant increase of intracranial or other critical organ bleedings. Our observational study aimed to describe the clinical performance, adherence, and persistence of DPI therapy among a real-world setting of patients with an established diagnosis of coronary artery (CAD) and/or peripheral artery disease (PAD). We prospectively included all consecutive patients with an established diagnosis of CAD and/or PAD treated with aspirin (ASA) 100 mg once daily and rivaroxaban 2.5 mg twice daily. Clinical evaluation was performed at baseline, before starting treatment, at 1 month, and every 6 months after the study drug administration. A total of 202 consecutive patients (mean age 66 ± 10 years; male 80%) eligible to DPI therapy were included. During a mean follow-up of 664 ± 177 days, the incidence rate of major bleedings and of major adverse cardiovascular events was 0.8 and 1.1 per 100 patients/year, respectively. The adherence to pharmacological treatment was 99%. Additionally, 13.4% of patients suspended the DPI therapy during the follow-up. Minor bleedings resulted the most common cause of both temporary and permanent DPI therapy discontinuation. This observational study supports the safety of DPI with low-dose rivaroxaban and aspirin among patients with CAD and PAD in a real-world setting, showing high persistence and maximum adherence to medical treatment.

RESUMEN

There is a relative scarcity of large-scale population studies investigating the relationship between the insulin resistance index of homeostasis model assessment (HOMA-IR) and vascular damage. Therefore, we assessed the association between HOMA-IR and vascular damage in adults aged 18 years and older in China. A total of 17,985 research subjects were included. Vascular damage markers and relevant laboratory tests were measured. HOMA-IR was calculated as (fasting insulin * fasting blood glucose)/22.5. Vascular damage included arteriosclerosis (ba-PWV > 1800 cm/s), peripheral artery disease (ABI < 0.9), and microalbuminuria (UACR > 30 mg/g). The relationship between HOMA-IR and vascular damage was analyzed using the RCS. The restricted cubic spline (RCS) analysis suggested that HOMA-IR was nonlinearly associated with arteriosclerosis (P for no-liner < 0.01), peripheral artery disease (P for no-liner < 0.01), and microalbuminuria (P for no-liner < 0.01). Further segmented regression analyses revealed that in study subjects with HOMA-IR < 5, we found that HOMA-IR was associated with an increased OR for arteriosclerosis (OR: 1.36, 95% CI (1.28, 1.45), P < 0.01), peripheral artery disease (OR: 1.33, 95% CI (1.10, 1.60), P < 0.01) and microalbuminuria (OR: 1.59, 95% CI (1.49, 1.70), P < 0.01). HOMA-IR is an independent risk factor for vascular damage, both macrovascular and microvascular. The phenomenon of saturation of HOMA-IR with vascular damage needs further investigation.

RESUMEN

OBJECTIVE: To assess the effects of colchicine, which has been shown to reduce the risks of coronary artery disease but scarcely studied in peripheral artery disease (PAD), on major adverse limb events (MALE) in patients with PAD. METHODS: This is a retrospective study based on a nationwide database. Patients who were diagnosed with PAD between 2010 and 2020 and prescribed with colchicine after the diagnosis of PAD were identified. Patients were then categorized into the colchicine or the control group according to drug use. Propensity score matching was performed to mitigate selection bias. Risks of MALE (including lower limb revascularization and nontraumatic amputation) and major adverse cardiovascular events were compared between the two groups. RESULTS: After patient selection and propensity score matching, there were 60,219 patients in both colchicine and control groups. After a mean follow-up of 4.5 years, the risk of MALE was significantly lower in the colchicine group compared with control (subdistribution HR, 0.75; 95% CI, 0.71 to 0.80), as were the incidence of both components of MALE, lower limb revascularization and major amputations. Colchicine treatment was also associated with lower risk of cardiovascular death. The lower risk of MALE observed with colchicine therapy was accentuated in the subgroup of patients receiving concomitant urate-lowering medications. CONCLUSION: In patients diagnosed with PAD, the use of colchicine is associated with lower risks of MALE and cardiovascular death. Anti-inflammatory therapy with colchicine may provide benefits in vascular beds beyond the coronary arteries.

RESUMEN

BACKGROUND: Atherosclerosis in more than 1 vs. 1 arterial bed is associated with increased risk for major adverse cardiovascular events (MACE). This study aimed to determine whether the risk of post percutaneous coronary intervention (PCI) MACE associated with polyvascular disease (PVD) differs by sex. METHODS: We analyzed 18,721 patients undergoing PCI at a tertiary-care center between 2012 and 2019. Polyvascular disease was defined as history of peripheral artery and/or cerebrovascular disease. The primary endpoint was MACE, a composite of all-cause death, myocardial infarction, or stroke at 1 year. Multivariate Cox regression was used to adjust for differences in baseline risk between patients with PVD vs. coronary artery disease (CAD) alone and interaction testing was used to assess risk modification by sex. RESULTS: Women represented 29.2% (N = 5,467) of the cohort and were more likely to have PVD than men (21.7% vs. 16.1%; P < .001). Among both sexes, patients with PVD were older with higher prevalence of comorbidities and cardiovascular risk factors. Women with PVD had the highest MACE rate (10.0%), followed by men with PVD (7.2%), women with CAD alone (5.0%), and men with CAD alone (3.6%). Adjusted analyses revealed similar relative MACE risk associated with PVD vs. CAD alone in women and men (adjusted hazard ratio [aHR] 1.54, 95% confidence interval [CI] 1.20-1.99; P < .001 and aHR 1.31, 95% CI 1.06-1.62; P = .014, respectively; p-interaction = 0.460). CONCLUSION: Women and men derive similar excess risk of MACE from PVD after PCI. The heightened risk associated with PVD needs to be addressed with maximized use of secondary prevention in both sexes.

RESUMEN

INTRODUCTION: Peripheral arterial disease (PAD) indicates generalised atherosclerotic disease but is often asymptomatic. The prevalence and potential risk factors of PAD were studied in ECHORN cohort study participants. METHODS: Representative samples of community-dwelling people ≥40 years of age residing in Barbados, Puerto Rico, Trinidad, and the USVI were recruited. The survey included questions on diabetes, hypertension, heart disease and smoking status. Body Mass Index, HbA1c, blood glucose and lipids were determined. Ankle brachial index (ABI) was evaluated in one leg. An oscillometric device measured arm and leg systolic BP simultaneously. ABI classifications were PAD ≤0.90, borderline 0.91 to 0.99, normal 1.00 to 1.40, and non-compressible >0.40. Multivariable logistic regression tested associations of potential risk factors with PAD. RESULTS: Of 2772 participants (mean age 57.3, 65.2% female), 35.8% were overweight, 38.1% obese, 32.4% had diabetes, 60% hypertension, and 15.4% reported heart. ABI prevalence (95% CI) by category was PAD 4.4% (3.6%, 5.1%), borderline 5.2% (4.4%, 6.1%), normal 87.0% (85.8%, 88.3%) and noncompressible 3.4% (2.7%, 4.0%). Female sex (OR 1.72, 95% CI 1.07 to 2.77), diabetes (OR 2.23, 95% CI 1.47 to 3.4), heart disease history (OR 1.74, 95% CI 1.07 to 2.83) and less than high school education vs having a university degree (OR 2.49, 95% CI 1.19 to 5.22) were independently associated with PAD. CONCLUSIONS: Testing one leg only would underestimate PAD prevalence. Increasing the ABI cutoff for identifying PAD to <1.0 when using oscillometric devices is suggested by some studies but would more than double the estimated prevalence. Guidelines need to address this issue. Female sex and lower educational attainment are important considerations when screening. While diabetes and a history of heart disease were confirmed as risk factors, the lack of association of increasing age and cigarette smoking with PAD was unexpected.

RESUMEN

BACKGROUND: The ankle-brachial index (ABI) is the ratio of the ankle and brachial systolic blood pressures. In the clinical setting, low ABI (< 0.9) is an indicator of peripheral atherosclerosis, while high ABI (> 1.4) is a sign of arterial stiffness and calcification. The purpose of the current study was to investigate the association between ABI and physical activity levels, measured by accelerometer. METHODS: The Swedish CArdioPulmonary bioImage Study (SCAPIS) is a Swedish nationwide population-based cross-sectional cohort for the study of cardiovascular and pulmonary diseases, in which individuals aged 50-64 years were randomly invited from the general population. The study population with data on ABI, physical activity, and sedentary time based on accelerometry was 27,737. Differences between ABI categories and associations to sedentary behavior, moderate to vigorous physical activity (MVPA), and other metabolic characteristics were compared. ABI was categorized as low, ABI ≤ 0.9, borderline, ABI 0.91-0.99, normal, ABI 1.0-1.39, and high, ABI ≥ 1.4. RESULTS: Prevalence of low ABI was higher in the most sedentary quartiles compared to the least sedentary (0.6% vs. 0.1%, p < 0.001). The most sedentary individuals also exhibited higher BMI, higher prevalence of diabetes and hypertension. The proportion of wake time spent in MVPA was lowest in those with low ABI (0.033 ± 0.004; p < 0.001) and highest in those with ABI > 1.4 (0.069 ± 0.001; p < 0.001) compared to those with normal ABI. Compared to normal ABI, the proportion of sedentary time was highest in those with low ABI (0.597 ± 0.012; p < 0.001) and lowest in those with ABI > 1.4 (0.534 ± 0.002; p = 0.004). CONCLUSION: This population-based study shows that middle-aged individuals with ABI > 1.4 have the highest level of physical activity, while individuals with a lower ABI, especially those with ABI < 0.9, are less active and spend more time sedentary. Future studies are needed to understand the relationships between ABI, physical activity, and the risk of peripheral arterial and cardiovascular disease in the general population.

RESUMEN

BACKGROUND: Lower extremity peripheral arterial disease is a potentially lethal cardiovascular complication in patients undergoing hemodialysis. Anemia is a risk factor for cardiovascular disease among the hemodialysis population. However, whether blood hemoglobin concentration is associated with the risk of peripheral arterial disease progression in this population remains undetermined. METHODS AND RESULTS: This is an extension of a 4-year multicenter, prospective, observational cohort study to 10 years. A total of 3504 Japanese patients undergoing maintenance hemodialysis were recruited between 2006 and 2007. The primary exposure was blood hemoglobin concentration at baseline. The main outcome was the first-ever incidence of major adverse limb events (MALE), composed of endovascular treatment, bypass surgery, and amputation. Multivariable-adjusted Cox proportional hazards model, Fine-Gray subdistribution hazards model, restricted cubic spline analysis, and restricted mean survival time analysis were used to determine the association of blood hemoglobin concentration with the incidence of MALE. During a median follow-up of 8.0 years, 257 patients experienced MALE. A Cox proportional hazards model showed that the risk of MALE in patients with blood hemoglobin concentrations <10.0 g/dL was significantly higher than in patients with concentrations of 11.0 to 11.9 g/dL, even after adjusting for confounding factors. In contrast, elevated hemoglobin concentration (≥12.0 g/dL) was not significantly associated with increased risk of MALE. Similar associations were observed when the Fine-Gray subdistribution regression model was used by setting all-cause mortality as the competing risk. CONCLUSIONS: A low blood hemoglobin concentration is an independent risk factor for peripheral arterial disease progression in patients undergoing maintenance hemodialysis.

RESUMEN

BACKGROUND: At present, no studies explored whether dietary fiber intake was associated with the risk of peripheral artery disease (PAD) in hypertensive patients. This study assessed the association between dietary fiber intake and PAD in hypertensive patients. METHODS: This cross-sectional study collected the data of 4628 participants with the measurement of ankle-brachial pressure index in the National Health and Nutrition Examination Surveys database. Univariate logistic regression analysis was applied to identify variables associated with PAD as confounding factors. Univariate and multivariable logistic regression analyses were used to explore the association between dietary fiber intake and PAD in hypertensive patients. Subgroup analysis was stratified by age, cardiovascular disease, dyslipidemia, diabetes, smoking, and physical activity. RESULTS: After adjusting for confounding factors, decreased risk of PAD was observed in hypertensive patients with dietary fiber intake > 21 g [odds ratio (OR) = 0.67, 95% confidence interval (CI) 0.46-0.99]. Compared with people with dietary fiber intake ≤ 21 g, those with dietary fiber intake > 21 g were associated with decreased risk of PAD in hypertensive patients < 60 years (OR = 0.23, 95%CI 0.08-0.66). In hypertensive patients without dyslipidemia, dietary fiber intake > 21 g were associated with reduced risk of PAD (OR = 0.33, 95%CI 0.12-0.95). Decreased risk of PAD was also found in hypertensive patients without diabetes in dietary fiber intake > 21 g group (OR = 0.50, 95%CI 0.31-0.78). Dietary fiber intake > 21 g was linked with reduced risk of PAD in hypertensive patients in never smoke group (OR = 0.46, 95%CI 0.24-0.86). CONCLUSION: Higher dietary fiber intake was associated with reduced risk of PAD in hypertensive patients, suggesting the importance of increase the daily dietary quality especially fiber intake in hypertensive people.

RESUMEN

BACKGROUND: Arterial and venous cardiovascular conditions, such as coronary artery disease (CAD), peripheral artery disease (PAD), and venous thromboembolism (VTE), are genetically correlated. Interrogating underlying mechanisms may shed light on disease mechanisms. In this study, we aimed to identify (1) epidemiological and (2) causal, genetic relationships between metabolites and CAD, PAD, and VTE. METHODS: We used metabolomic data from 95 402 individuals in the UK Biobank, excluding individuals with prevalent cardiovascular disease. Cox proportional-hazards models estimated the associations of 249 metabolites with incident disease. Bidirectional 2-sample Mendelian randomization (MR) estimated the causal effects between metabolites and outcomes using genome-wide association summary statistics for metabolites (n=118 466 from the UK Biobank), CAD (n=184 305 from CARDIoGRAMplusC4D 2015), PAD (n=243 060 from the Million Veterans Project), and VTE (n=650 119 from the Million Veterans Project). Multivariable MR was performed in subsequent analyses. RESULTS: We found that 196, 115, and 74 metabolites were associated (P<0.001) with CAD, PAD, and VTE, respectively. Further interrogation of these metabolites with MR revealed 94, 34, and 9 metabolites with potentially causal effects on CAD, PAD, and VTE, respectively. There were 21 metabolites common to CAD and PAD and 4 common to PAD and VTE. Many putatively causal metabolites included lipoprotein traits with heterogeneity across different sizes and lipid subfractions. Small VLDL (very-low-density lipoprotein) particles increased the risk for CAD while large VLDL particles decreased the risk for VTE. We identified opposing directions of CAD and PAD effects for cholesterol and triglyceride concentrations within HDLs (high-density lipoproteins). Subsequent sensitivity analyses including multivariable MR revealed several metabolites with robust, potentially causal effects of VLDL particles on CAD. CONCLUSIONS: While common vascular conditions are associated with overlapping metabolomic profiles, MR prioritized the role of specific lipoprotein species for potential pharmacological targets to maximize benefits in both arterial and venous beds.

RESUMEN

BACKGROUND: Genome wide association studies (GWAS) have allowed for a rapid increase in our understanding of the underlying genetics and biology of many diseases. By capitalizing on common genetic variation between individuals, GWAS can identify DNA variants associated with diseases of interest. A variety of statistical methods can be applied to GWAS results which allows for risk factor identification, stratification, and to identify potential treatments. Peripheral artery disease (PAD) is a common vascular disease that has been shown to have a strong genetic component. This article provides a review of the modern literature and our current understanding of the role of genetics in PAD. METHODS: All available GWAS studies on PAD were reviewed. A literature search involving these studies was conducted and relevant articles applying the available GWAS data were summarized to provide a comprehensive review of our current understanding of the genetic component in PAD. RESULTS: The largest available GWAS on PAD has identified 19 genome wide significant loci, with factor V Leiden and genes responsible for circulating lipoproteins being implicated in the development of PAD. Mendelian randomization (MR) studies have identified risk factors and causal associations with smoking, diabetes, and obesity and many other traits; protein-based MR has also identified circulating lipid and clotting factor levels associated with the incidence of PAD. Polygenic risk scores may allow for improved prediction of disease incidence and allow for early identification of at-risk patients but more work needs to be done to validate this approach. CONCLUSIONS: Genetic epidemiology has allowed for an increased understanding of PAD in the past decade. Genome-wide association studies have led to improved detection of genetic contributions to PAD, and further genetic analyses have validated risk factors and may provide options for improved screening in at-risk populations. Ongoing biobank studies of chronic limb threatening ischemia patients and the increasing ancestral diversity in biobank enrollment will allow for even further exploration into the pathogenesis and progression of PAD.

RESUMEN

BACKGROUND AND AIMS: Peripheral artery disease (PAD) has not only been associated with recurrent hospitalization for acute decompensated heart failure (ADHF) but is also associated with chronic kidney disease (CKD), a known risk factor for worse heart failure outcomes. The interaction of CKD with PAD in post-discharge ADHF outcomes is not well known. METHODS: Since 2005, hospitalizations for ADHF were sampled from 4 US regions by the Atherosclerosis Risk in Communities (ARIC) study and classified by physician review. We examined the adjusted association of PAD with 1-year ADHF readmissions, in patients with and without CKD (defined by glomerular filtration rate [GFR] ≤60 mL/min/1.73 m2 [stage 3a or worse]). RESULTS: From 2005 to 2018, there were 1049 index hospitalizations for patients with ADHF (mean age 77 years, 66 % white) with creatinine data, who were discharged alive. Of these, 155 (15 %) had PAD and 66 % had CKD. In comparison to those without PAD, patients with PAD had more comorbid conditions and higher 1-year ADHF readmission rates, irrespective of CKD status. After adjustment, PAD was associated with a greater risk of 1-year ADHF readmissions, both for patients with concomitant CKD (HR, 1.70; 95 % CI: 1.29-2.24) and those without CKD (HR, 1.97; 95 % CI: 1.14-3.40); p-interaction = 0.8. CONCLUSION: Among patients hospitalized with ADHF, those with concurrent PAD have more prevalent cardiovascular comorbidities and higher likelihood of 1-year ADHF readmission, irrespective of CKD status. Integrating a more holistic approach in management of patients with concomitant heart failure, PAD and CKD may be an important strategy to improve the prognosis in this vulnerable population.

RESUMEN

BACKGROUND: There is a dearth of research on immunophenotyping in peripheral artery disease (PAD). This study aimed to describe the baseline characteristics, immunophenotypic profile, and quality of life (QoL) of participants with PAD in the Project Baseline Health Study (PBHS). METHODS: The PBHS study is a prospective, multicenter, longitudinal cohort study that collected clinical, molecular, and biometric data from participants recruited between 2017 and 2018. In this analysis, baseline demographic, clinical, mobility, QoL, and flow cytometry data were stratified by the presence of PAD (ankle brachial index [ABI] ≤0.90). RESULTS: Of 2,209 participants, 58 (2.6%) had lower-extremity PAD, and only 2 (3.4%) had pre-existing PAD diagnosed prior to enrollment. Comorbid smoking (29.3% vs 14%, P < .001), hypertension (54% vs 30%, P < .001), diabetes (25% vs 14%, P = .031), and at least moderate coronary calcifications (Agatston score >100: 32% vs 17%, P = .01) were significantly higher in participants with PAD than in those with normal ABIs, as were high-sensitivity C-reactive protein levels (5.86 vs 2.83, P < .001). After adjusting for demographic and risk factors, participants with PAD had significantly fewer circulating CD56-high natural killer cells, IgM+ memory B cells, and CD10/CD27 double-positive B cells (P < .05 for all). CONCLUSIONS: This study reinforces existing evidence that a large proportion of PAD without claudication may be underdiagnosed, particularly in female and Black or African American participants. We describe a novel immunophenotypic profile of participants with PAD that could represent a potential future screening or diagnostic tool to facilitate earlier diagnosis of PAD.

RESUMEN

Surgical site infections (SSIs) following major lower limb amputation (MLLA) in vascular patients are a major source of morbidity. The objective of this systematic review was to determine the incidence of SSI following MLLA in vascular patients. This review was prospectively registered with the International Prospective Register of Systematic Reviews (CRD42023460645). Databases were searched without date restriction using a pre-defined search strategy. The search identified 1427 articles. Four RCTs and 21 observational studies, reporting on 50 370 MLLAs, were included. Overall SSI incidence per MLLA incision was 7.2% (3628/50370). The incidence of SSI in patients undergoing through-knee amputation (12.9%) and below-knee amputation (7.5%) was higher than the incidence of SSI in patients undergoing above-knee amputation, (3.9%), p < 0.001. The incidence of SSI in studies focusing on patients with peripheral arterial disease (PAD), diabetes or including patients with both was 8.9%, 6.8% and 7.2%, respectively. SSI is a common complication following MLLA in vascular patients. There is a higher incidence of SSI associated with more distal amputation levels. The reported SSI incidence is similar between patients with underlying PAD and diabetes. Further studies are needed to understand the exact incidence of SSI in vascular patients and the factors which influence this.

RESUMEN

BACKGROUND: Bilateral blood pressure (BP) measurement is important in cardiovascular prevention for identifying systolic interarm BP difference (IAD) and hypertension. We investigated sex-stratified IAD prevalence and its associations and coexistence with screen-detected peripheral atherosclerosis and hypertension. Furthermore, we determined the proportion misclassified as non-hypertensive when using the lower versus the higher reading arm. METHODS: This sub-study formed part of the Viborg Screening Program (VISP), a cross-sectorial population-based cardiovascular screening programme targeting 67-year-old Danes. VISP includes screening for peripheral atherosclerosis (lower extremity arterial disease and carotid plaque), abdominal aortic aneurysm, hypertension, diabetes mellitus, and cardiac disease. Self-reported comorbidities, risk factors, and medication use were also collected. Among 4,602 attendees, 4,517 (82.1%) had eligible bilateral and repeated BP measurements. IAD was defined as a systolic BP difference ≥ 10 mmHg. IAD-associated factors (screening results and risk factors) were estimated by logistic regression; proportional coexistence was displayed by Venn diagrams (screening results). RESULTS: We included 2,220 women (49.2%) and 2,297 men (50.8%). IAD was more predominant in women (26.8%) than men (21.0%) (p < 0.001). This disparity persisted after adjustment [odds ratio (OR) 1.53; 95% confidence interval (CI) 1.32-1.77]. No other association was recorded with the conditions screened for, barring potential hypertension: BP 140-159/90-99 mmHg (OR 1.68, 95% CI 1.44-1.97) and BP ≥ 160/100 mmHg (OR 1.82, 95% CI 1.49-2.23). Overall, IAD and BP ≥ 160/100 mmHg coexistence was 4% in women and 5% in men; for BP ≥ 140/90 mmHg, 13% and 14%, respectively. Among those recording a mean BP ≥ 140/90 mmHg in the higher reading arm, 14.5% of women and 15.3% of men would be misclassified as non-hypertensive compared with the lowest reading arm. CONCLUSION: Female sex was an independent factor of IAD prevalence but not associated with other arterial lesions. Approximately 15% needed reclassification according to BP ≥ 140/90 mmHg when the lower rather than the higher reading arm was used; verifying bilateral BP measurements improved detection of potential hypertension. In future, the predictive value of sex-stratified IAD should be assessed for cardiovascular events and death to verify its potential as a screening tool in population-based cardiovascular screening.
