The objective of the present study was define in a relatively large patient population with coronary artery disease (CAD) whether the concomitant presence of peripheral artery disease (PAD), which is known to convey additional cardiovascular risk, was associated with different circulating levels of sRAGE with respect to CAD alone and control subjects. Clinical and laboratory parameters including the ankle brachial index (ABI) and sRAGE (enzyme-linked immunosorbent assay kit) were investigated in 544 patients with angiographically documented CAD and 328 control subjects. 213/554 CAD patients (39%) showed an ABI <0.9 associated with typical symptoms (group CAD + PAD), whereas 331 patients were free from PAD. The concentration of plasma sRAGE was significantly lower (P<0.0001) in CAD population, with and without PAD, than in control subjects. Among CAD patients, those with PAD showed lower levels of sRAGE. The distribution of the three groups (CAD, CAD + PAD, and controls) according to sRAGE tertiles showed that lower levels were more frequent in patients with CAD and CAD + PAD, whereas higher levels were more frequently found in controls. CAD patients presenting with PAD have lower sRAGE levels than CAD patients without peripheral atherosclerosis showing that stable atherosclerotic lesions in different vascular districts are inversely related to soluble decoy receptor sRAGE.

IntroductionIt is common for patients with PAD to have concomitant CAD because both are caused by atherosclerosis, a systemic process. This has been well established in international studies. The incidence of PAD in patients with known CAD in our population is unknown. The ankle brachial index (ABI) can be calculated by taking the ratio of ankle systolic pressure and brachial systolic pressure. It is a simple, easy and cost effective bedside tool to diagnose peripheral arterial disease (PAD).Objective:The objective of the study was to:Determine the incidence of PAD in patients with known coronary artery disease (CAD) in our population.Determine the diagnostic accuracy of ABI in diagnosing PAD in patients with CAD taking dup-lex ultrasound as gold standard in local population.Study Design: Cross sectional study.Setting:Department of Cardiology (CCU), Jinnah Hospital, Lahore.Study Duration:Six months from 01 June 2014 to 31 December 2014.Subjects and Methods:310 patients who met the inclusion / exclusion criteria were entered in the study. Mercury sphygmomanometer was used to take the systolic blood pressure of all the four limbs, and the ratio of ankle systolic pressure (higher of systolic pressure taken in both left and right limb was taken) to brachial systolic pressure (higher of systolic pressure taken in both left and right limb was taken) was used to calculate the ABI. An abnormal ABI was conside-red if the ratio was < 0.9. All subjects underwent duplex ultrasound as a gold standard to detect the presence or absence of PAD.Results:Out of 310 cases, common age was calcula-ted as 59.21 8.93 years, 53.23% (n = 165) were male while 46.77% (n = 145) were female, frequency of peripheral artery disease (PAD) on gold standard was recorded as 28.71% (n = 89), diagnostic accuracy of Ankle-Brachial Index (ABI) in diagnosing peripheral artery disease (PAD) in patients with coronary artery disease (CAD) was calculated as 93.25%, 94.21%, 86.46%, 97.20% and 93.87% as specificity, sensitivity, negative predictive value, positive predictive value and accuracy rate respectively.Conclusion:There is a 28.7% incidence of PAD in patients with known CAD in our study population. The ABI is a simple, easy low cost and yet underutilized tool that can detect PAD with high diagnostic accuracy in this population.Keywords:Coronary artery disease (CAD), peripheral artery disease (PAD), diagnosis, ankle bra-chial index (ABI), accuracy

Distinct Features

Coronary artery disease (CAD) patients with concomitant peripheral artery disease (PAD) experience more extensive and calcified atherosclerosis, greater lesion progression and more common coronary events compared to patients with CAD only. To characterize the distinct features of this aggressive atherosclerotic disease, we studied novel cytokines that code different stages of atherogenesis. One hundred and eighty consecutive subjects (60 patients into each group of CAD+PAD, CAD and controls) were recruited among patients with stable angina pectoris scheduled for coronary angiography. An ankle–brachial index (ABI) ≤0.9 was determined as occlusive PAD. Fasting serum tumor necrosis factor (TNF)-like antigen 1A (TL1A) and its receptor death receptor 3 (DR3), NOGO-B (reticulon 4B) and its receptor NUS1, high-sensitivity C-reactive protein (hsCRP), A disintegrin and metalloproteinase with thrombospondin motifs (ADAMTS) 1, 4, 5 and interleukin (IL) 6 levels were determined. Serum hsCRP and DR3/TL1A concentrations were similar and higher than controls in the CAD and CAD+PAD groups. Levels of NOGO-B and its receptor NUS1 were increased and ADAMTS-5 was decreased in patients with CAD+PAD. Independent predictors of ABI in multivariate analysis were smoking (B = −0.13, p = 0.04), NUS1 (B = −0.88, p < 0.001), ADAMTS-5 (B = 0.63, p < 0.001) and SYNTAX score (B = −0.26, p < 0.001). Similarly, smoking (OR = 5.5, p = 0.019), SYNTAX score (OR = 1.2, p < 0.001), NUS1 (OR = 14.4, p < 0.001), ADAMTS-5 (OR = 1.1, p < 0.001) and age (OR = 1.1, p = 0.042) independently predicted the involvement of peripheral vasculature in logistic regression. The diagnostic performance of these cytokines to discriminate CAD+PAD were AUC 0.79 ( p < 0.001) for NUS1 and 0.37 ( p = 0.013) for ADAMTS-5. We report herein that circulating cytokines can give clues to the ongoing atherosclerotic process and the extent of vascular involvement in which distinct features of ADAMTS-5 and NUS1 make them promising cytokines for future research.

We evaluated angiogenin as a prospective biomarker in peripheral artery disease (PAD) patients with and without claudication symptoms. A pilot study suggested an elevation of angiogenin in critical limb ischemia. However, in PAD patients, the predictive value of angiogenin has not yet been evaluated. For this purpose, 342 patients with PAD (age: 69 ± 10 years, 34.5% women) were followed-up for 7 years in a cross-sectional study. Angiogenin was measured by enzyme-linked immunosorbent assay. All-cause and cardiovascular mortality were analyzed by Cox regression. Angiogenin levels were higher in men ( P = .001) and were associated with patient waist-to-hip ratio ( P < .001), fasting triglycerides ( P = .011), and inversely with estimated glomerular filtration rate ( P = .009). However, angiogenin showed no association with age, characteristics of diabetes, markers of lipid metabolism, or C-reactive protein. Angiogenin did not correlate with markers of angiogenesis such as vascular endothelial growth factor, angiopoietin-2, or tie-2. Furthermore, angiogenin was not associated with PAD Fontaine stages or with patient ankle-brachial index in addition to all-cause mortality (hazard ratio [HR] = 1.09 [95% CI: 0.89-1.34]) or cardiovascular morality (HR = 1.05 [0.82-1.35]). These results suggest that angiogenin does not provide further information regarding outcome prediction in patients with PAD.

Abstract Coronary Artery Disease (CAD) is a chronic inflammatory disease caused by atherosclerosis and arteries become clogged due to plaque formation, fat accumulation, and various sorts of immune cells. IL-32 is a new proinflammatory cytokine, which enhances inflammation through inducing different inflammatory cytokines. The purpose of current research was to assess IL-32 serum levels in coronary artery disease subjects and its relationship with serum levels of IL-6 and TNF-α. Forty-two subjects diagnosed with CAD and thirty-nine control subjects were enrolled in the research. Serum levels of IL-6, TNF-α, and IL-32 were measured using the enzyme-linked immunosorbent assay (ELISA). IL-32, TNF-α, and IL-6 serum levels were significantly higher by 2.7, 3.48, and 3.2-fold in the CAD subjects than in control subjects, respectively. Moreover, no significant difference was found in TNF-α, IL-6 and IL-32 serum levels with the clogged arteries number in the CAD group. TNF-α and IL-32 serum levels in the CAD subjects with cardiac arterial stenosis in one major vessel were significantly increased than CAD subjects with cardiac arterial stenosis in more than one major vessels. ROC curve analysis revealed that serum levels of IL-32, TNF-α, and IL-6 showed good abilities in predicting CAD. Also, Multiple logistic regression analyses suggested that TNF-α, IL-6, and IL-32, serum levels of LDL and ox-LDL were independently related to the presence of CAD, while HDL serum levels were not. TNF-α, IL-32, and IL-6 showed an increase in CAD group and serum levels of these cytokines showed good abilities in predicting CAD. Our data suggested the involvement of TNF-α and IL-32 in the early stage of CAD.
