Abstract
OBJECTIVE To evaluate, with real world data (SIDIAP and CMBD), the evolution of the prevalence of peripheral arterial disease (PAD) in the Catalan population and the cardiovascular risk factors present in people with this pathology. DESIGN Longitudinal descriptive population study. SITE: Primary health care. PARTICIPANTS Patients listed in SIDIAP and CMBD with a diagnosis of peripheral artery disease between 2008 and 2018 ≥ 35 years, as well as those without a diagnosis, but with an ABI < 0.9 in SIDIAP. INTERVENTIONS AND MAIN MEASUREMENTS Main variable AP (ICD-9, ICD-10). Sociodemographic data, risk factors and cardiovascular disease, drug use and prevalent cardiovascular events at the time of diagnosis. RESULTS 141,520 patients were studied. 75% had hypertension, 58% were smokers or former smokers, and 23% had a myocardial infarction. The global prevalence increased from 1.15% in 2008 to 3.10% in 2018. The prevalence of PAD increased with age, with a moderate increase at younger ages, and more pronounced in > 55 years, exceeding 10% in > 85 years. CONCLUSION This is a population study where it is observed that the evolution of the prevalence of peripheral artery disease has presented a constant increase during the years 2008-2018, being higher in men, especially from 55 years of age. Studies with large databases can facilitate the design and implementation of new policies in national health systems.

Abstract
Background Peripheral artery disease (PAD) is associated with cardiovascular risk in type 2 diabetes mellitus (DM). The ankle-brachial index (ABI) is used for diagnosis of PAD. Objectives Establish the prevalence and incidence rate for PAD and determine the associated factors and survival time for the development of PAD. Methods Retrospective cross-sectional cohort study (follow up: 10 years) in 578 DM patients with at least 1 ABI measurement in a primary level of care diabetes clinic. Data was collected from clinical records. Sociodemographic and laboratory variables were analyzed determining its association (mean difference and bivariate logistic regression). Survival was calculated through life tables and Kaplan-Meier analysis. Results The prevalence of PAD was 13.98%. The incidence rate through the time of follow up was 23.38 per 1000 person-year (95% CI: 19.91-27.26). The group that developed PAD showed higher glycated hemoglobin levels ( P = .025), more years of DM ( P < .001) and lower glomerular filtration rate (GFR, P = .003). The median time for developing PAD was 26.97 years (95% CI: 26.89-27.05). The risk for PAD was higher in females (95% CI: 1.51-4.38), GFR <60 mL/min/m2 (95% CI: 1.05-2.22) and use of metformin plus insulin (95% CI: 1.10-2.35). Conclusion Half of a DM patient’s population in primary level of care will develop PAD in the third decade of disease. There are identifiable risk factors for PAD development in DM in the primary level of care such as low GFR, female sex, and use of metformin plus insulin.

Abstract
BACKGROUND Peripheral arterial disease is very common in patients with diabetes, but it remains grossly under-recognized in this type of patients. Ankle brachial index (ABI) is a simple, non-invasive and reproducible method for detection and improving risk stratification. However, the sensitivity appears to be lower in diabetic patients and, false 'high' readings occur because of the arterial calcification of the vessel media which render the vessels incompressible. MATERIALS AND METHODS The study evaluated the prevalence of a low ABI <0.9 in diabetic patients in a hospital-based cross sectional observational study. The study has been registered. RESULTS The prevalence of peripheral arterial disease in diabetics with ABI< 0.9 was 18%. The majority (77%) of responders were asymptomatic with mild PAD (ABI 0.7-0.9). Age >60 years, hypertension (systolic BP > 140 mmHg) and presence of foot ulcer were identified as independent risk factors. 22 participants (4.4%) of the 500 had ABI greater than 1.3 but were excluded in the analysis. CONCLUSION The prevalence of PAD in diabetics measured by the ABI index was low and the majority in our setting had mild PAD and were asymptomatic. ABI could be used in patients with diabetes, but values should be interpreted with precision, according to the clinical situation as higher values are common.

Abstract
This study aimed to determine associations between ankle-brachial index (ABI) and brachial-ankle pulse wave velocity (baPWV) with different comorbidities in patients with type 2 diabetes mellitus (DM). Records of patients with type 2 DM who received an ABI and baPWV examination between August 2013 and February 2015 were retrospectively reviewed. Associations of ABI and baPWV with chronic kidney disease (CKD), chronic liver disease (CLD), coronary artery disease (CAD) and diabetic nephropathy (DN) were examined by regression analysis. A total of 1232 patients (average age, 65.1±10.0 years) were included in the analysis. CKD and DN were associated with low ABI and increased baPWV (all, P<0.001). No associations were found between CAD and CLD and ABI or baPWV. Thus, regression analysis was performed for CKD and DN. Low ABI was associated with risk of CKD in the crude model (OR 0.724, 95% CI 0.648 to 0.808, P<0.001) and adjusted model (OR 0.872, 95% CI 0.762 to 0.999, P=0.048), whereas baPWV was only significant in the crude model (OR 1.199, 95% CI 1.112 to 1.294, P<0.001). Low ABI was associated with risk of DN in the crude model (OR 0.873, 95% CI 0.780 to 0.977, P=0.018) and adjusted model (OR 0.884, 95% CI 0.782 to 0.999, P=0.048). No association was found for baPWV. In conclusion, low ABI was associated with risk of CKD and DN in patients with type 2 diabetes.

Abstract
Peripheral arterial disease, manifested as intermittent claudication or critical ischaemia, or identified by an ankle/brachial index < 0.9, is present in at least one in every four patients with type 2 diabetes mellitus. Several reasons exist for peripheral arterial disease in diabetes. In addition to hyperglycaemia, smoking and hypertension, the dyslipidaemia that accompanies type 2 diabetes and is characterised by increased triglyceride levels and reduced high-density lipoprotein cholesterol concentrations also seems to contribute to this association. Recent years have witnessed an increased interest in postprandial lipidaemia, as a result of various prospective studies showing that non-fasting triglycerides predict the onset of arteriosclerotic cardiovascular disease better than fasting measurements do. Additionally, the use of certain specific postprandial particle markers, such as apolipoprotein B-48, makes it easier and more simple to approach the postprandial phenomenon. Despite this, only a few studies have evaluated the role of postprandial triglycerides in the development of peripheral arterial disease and type 2 diabetes. The purpose of this review is to examine the epidemiology and risk factors of peripheral arterial disease in type 2 diabetes, focusing on the role of postprandial triglycerides and particles.

Abstract
INTRODUCTION Peripheral artery disease in the lower limbs (PAD) is a prevalent condition that entails high morbidity in diabetic patients; this study assesses PAD in these patients and its socio-demographic and clinic associated variables. MATERIAL AND METHODS Descriptive study in a systematic sample of diabetic patients (DM2) aged 50-80 years, in Primary Care settings. The dependent variable was the presence of PAD diagnosed by ankle-brachial index (ABI) ≤ 0.9; independent variables: socio-demographic, clinical and laboratory. STATISTICS bivariate and multiple logistic regression analyses were performed to determine the variables associated with low ABI. RESULTS A sample of 251 patients, 52.6% women; mean age: 68.5 ±8.5. A low ABI was detected in 18.3% (95% Confidence Interval (95% CI):13.3-23.3%), with 6 subjets (2.4%) previously diagnosed as suffering PAD. Age (OR=1.07; 95% CI: 1.02-1.12) and retinopathy (OR=2.69; 95% CI: 1.06-6.81) were associated (multiple logistic regression analysis) with ABI. CONCLUSIONS The percentage of patients diagnosed with PAD is very low, although PAD prevalence is high among DM2 patients attending Primary Care clinics, especially in older patients and those with retinopathy. We emphasize the recommendation of performing the ABI test in this population at risk.

Abstract
We investigated the prevalence of peripheral vascular disease (PVD) and its association with preclinical atherosclerotic markers [intima-media thickness (IMT)] and arterial stiffness among 1755 urban south Indian type 2 diabetic subjects recruited from the Chennai Urban Rural Epidemiology Study (CURES). Doppler studies were performed, and PVD was defined as ankle-brachial index (ABI) of ≤0.9. IMT of the common carotid artery was determined using high-resolution B-mode ultrasonography, and augmentation index (AGI) was measured using the Sphygmocor apparatus. The overall prevalence of PVD was 8.3% (age-standardized 6.5%). The prevalence of PVD was higher among known diabetic subjects (n = 1401) compared to newly detected diabetic subjects (n = 354) (8.6% vs 6.8%, p = 0.250). The mean IMT and AGI in subjects with PVD were significantly higher compared to subjects without PVD (IMT: 0.99 ± 0.26 mm vs 0.83 ± 0.19 mm; AGI: 28.1 ± 9.6% vs 25.7 ± 9.8%, respectively). IMT was independently associated with PVD even after adjusting for age [odds ratio (OR) = 2.9 (1.2-6.7), p = 0.016 for second tertile and OR = 3.9 (1.7-9.3), p = 0.002 for third tertile compared to first tertile]. AGI was also associated with PVD in the unadjusted model [OR = 1.8 (1.1-3.1), p = 0.027 for second tertile compared to first tertile]. However, when adjusted for age, the significance was lost. In conclusion, among urban south Indian type 2 diabetic subjects, the prevalence of PVD is 8.3% and IMT is more strongly associated with PVD than AGI.

Abstract
Peripheral arterial disease (PAD) refers to the atherosclerotic involvement of non-coronary and extracranial arteries, including visceral arteries, the aorta and its branches and the arteries of the limbs. PAD usually refers exclusively to atherosclerosis of the limbs (in particular the lower limbs). Age, male sex, smoking and diabetes, as well as hypertension and dyslipidemia, are the most relevant risk factors for the development of PAD. PAD is frequently associated with coronary heart disease and stroke. PAD patients have increased risk of developing cardiovascular complications (coronary disease, stroke) and total and cardiovascular mortality, even after adjustment by conventional risk factors. Despite this PAD exhibit a worse control of risk factors. This opens up an important opportunity to optimize their control, which can result in an improvement of the prognosis of patients with PAD. Ischemic nephropathy includes a constellation of disorders that are frequently associated: hypertension, renal failure and renal artery stenosis (RAS). RAS risk factors are similar to those of PAD. Recent studies have shown that renal revascularization is not associated with improvement in blood pressure control, preservation of renal function or reduction of cardiovascular events in most patients. Therefore, revascularization should be reserved for selected cases on an individual basis. In all cases, a strict control of vascular risk factors should be attempted.

Abstract
BACKGROUND The Ankle-Brachial Index (ABI) objectively assesses the lower extremity arterial perfusion. A low ABI suggests atherosclerosis and Peripheral Arterial Disease (PAD). PAD is more common in individuals with type2 Diabetes mellitus (Type2 DM). Inflammatory markers are found to be associated with Type2 DM. But the association of the inflammatory markers with the atherosclerotic burden remains poorly defined. AIMS To compare the ABI and the hsCRP in the Type 2 DM patients with those in the normal subjects and to study the association of serum hsCRP with ABI in the Type 2 DM patients and in normal subjects. METHODS The subjects were 40 Type2 DM and 40 age, sex and BMI matched normal subjects who were aged between 45-60 yrs. The subjects were assigned to two different groups, Group1- the Type2 DM patients and Group2- the healthy controls. The serum hsCRP levels were determined by the turbidimetry method (BIOSYSTEMS) and the ABI values were determined by using the traditional continuous wave (CW) Doppler of NICOLET VERSALAB. STATISTICAL ANALYSIS The data was analyzed by using the Student's t test (two tailed; independent) to find the significance of the study parameters between the two groups. Pearson's Correlation was used to find the correlation of serum hsCRP with the ABI in the two groups. RESULTS The ABI showed a significantly low value (P=0.035*) and the serum hsCRP showed a trend towards a significant increase (p = 0.069+) in the type2diabetics as compared to those in the normals. There was a significant negative correlation between ABI and hsCRP in the Type 2 DM patients (r=-0.560, p<0.001**). However, such correlation was not observed in the normal subjects. CONCLUSION As serum hsCRP is associated with ABI in the type2 DM patients, inflammation may play a role in the pathogenesis of atherosclerosis.

Abstract
BACKGROUND Upper arm automated blood pressure devices are widely available and could be used to estimate the ankle-brachial index. METHODS We conducted a trial to determine the equivalence of ankle-brachial index estimated by an upper arm blood pressure measuring device as index method compared to the handheld Doppler method as the reference standard. A total of 110 patients with diabetes mellitus were sequentially examined by two methods. RESULTS The prevalence of peripheral arterial disease was 32%. The index method obtained valid measurements in 104 (95%) patients. Ankle-brachial index was lower with the index method compared to the reference standard (mean difference: -0.05; 95% confidence interval [CI]: -0.50 to 0.39). This confidence interval was above the boundaries clinically established as equivalence margins in our study. The kappa agreement between two methods was 0.45. The performance of the index method was: sensitivity: 67%; specificity: 87%; positive likelihood ratio: 5.25; negative likelihood ratio: 0.18; positive predictive value: 71%; negative predictive value: 85%; and the area under the receiving operating characteristic curve: 0.87 (95% CI: 0.78-0.93). CONCLUSION Upper arm automated blood pressure measuring devices cannot replace the handheld Doppler method to estimate the ankle-brachial index in patients with diabetes mellitus.

Abstract
BACKGROUND The early diagnosis of atherosclerotic disease is essential for developing preventive strategies in populations at high risk and acting when the disease is still asymptomatic. A low ankle-arm index (AAI) is a good marker of vascular events and may be diminished without presenting symptomatology (silent peripheral arterial disease). The aim of the PERART study (PERipheral ARTerial disease) is to determine the prevalence of peripheral arterial disease (both silent and symptomatic) in a general population of both sexes and determine its predictive value related to morbimortality (cohort study). METHODS/DESIGN This cross-over, cohort study consists of 2 phases: firstly a descriptive, transversal cross-over study to determine the prevalence of peripheral arterial disease, and secondly, a cohort study to evaluate the predictive value of AAI in relation to cardiovascular morbimortality. From September 2006 to June 2007, a total of 3,010 patients over the age of 50 years will be randomly selected from a population adscribed to 24 healthcare centres in the province of Barcelona (Spain). The diagnostic criteria of peripheral arterial disease will be considered as an AAI < 0.90, determined by portable Doppler (8 Mhz probe) measured twice by trained personnel. Cardiovascular risk will be calculated with the Framingham-Wilson tables, with Framingham calibrated by the REGICOR and SCORE groups. The subjects included will be evaluted every 6 months by telephone interview and the clnical history and death registries will be reviewed. The appearance of the following cardiovascular events will be considered as variables of response: transitory ischaemic accident, ictus, angina, myocardial infartction, symptomatic abdominal aneurysm and vascular mortality. DISCUSSION In this study we hope to determine the prevalence of peripheral arterial disease, especially the silent forms, in the general population and establish its relationship with cardiovascular morbimortality. A low AAI may be a better marker of arterial disease than the classical cardiovascular risk factors and may, therefore, contribute to improving the predictive value of the equations of cardiovascular risk and thereby allowing optimisation of multifactorial treatment of atherosclerotic disease.
