Background:Chemokine-driven migration of inflammatory cells has been implicated in the pathogenesis of atherosclerotic conditions including peripheral arterial disease (PAD). Monocyte chemoattractant protein-1 (MCP-1) is elevated in patients with coronary artery disease and in hypertensive patients. This study therefore investigated MCP-1 in patients with PAD.Methods:Serum MCP-1 was determined by enzyme-linked immunosorbent assay in 36 healthy, control subjects and in 19 patients with PAD. Statistical analysis utilised the Mann-Whitney test and Spearman correlation(p<0.05).Results:MCP-1 (pg/ml) was increased in patients compared with in controls (mean±standard error of the mean: PAD group, 748±60; control group, 459±27; p=0.0001). MCP-1 levels tended to decrease with progressing disease. From atherosclerosis risk factors, diabetes inclined to increase MCP-1 levels; hypertension had no effect. Serum MCP-1 correlated with cholesterol, triglycerides, low-density lipoprotein but not high-density lipoprotein.Conclusion:Elevation of MCP-1 in the circulation of PAD patients shown in the present pilot study implicates this CC chemokine ligand 2 in inflammatory processes contributing to PAD clinical symptomatology. Further investigations are necessary to evaluate whether MCP-1 can be used as a potential marker of peripheral arterial disease follow-up and/or prognosis.

AbstractExercise training influences the risk of vascular thrombosis in patients with peripheral arterial disease (PAD). Mitochondrial functionalities in platelets involve the cellular bioenergetics and thrombogenesis. This study aimed to elucidate the effect of cycling exercise training (CET) on platelet mitochondrial bioenergetics in PAD patients. Forty randomly selected patients with PAD engaged in general rehabilitation (GR) with CET (i.e., cycling exercise at ventilation threshold for 30 minute/day, 3 days/week) (GR + CET, n = 20) or to a control group that only received GR course (n = 20) for 12 weeks. Systemic aerobic capacity and platelet mitochondrial bioenergetics that included oxidative phosphorylation (OXPHOS) and electron transport system (ETS) were measured using automatic gas analysis and high-resolution respirometry, respectively. The experimental results demonstrated that GR + CET for 12 weeks significantly (1) elevated VO2peak and lowered VE-VCO2 slope, (2) raised resting ankle-brachial index and enhanced cardiac output response to exercise, (3) increased the distance in 6-minute walk test and raised the Short Form-36 physical/mental component scores, and (4) enhanced capacities of mitochondrial OXPHOS and ETS in platelets by activating FADH2 (complex II)-dependent pathway. Moreover, changes in VO2peak levels were positively associated with changes in platelet OXPHOS and ETS capacities. However, no significant changes in systemic aerobic capacity, platelet mitochondrial bioenergetics, and health-related quality of life (HRQoL) occurred following GR alone. Hence, we conclude that CET effectively increases the capacities of platelet mitochondrial bioenergetics by enhancing complex II activity in patients with PAD. Moreover, the exercise regimen also enhanced functional exercise capacity, consequently improving HRQoL in PAD patients.

Abstract Background Elevated lipoprotein (a) [LP (a)] levels are an independent, genetic, and causal factor for cardiovascular disease and associated with myocardial infarction (MI). Although the association between circulating levels of lipoprotein(a) [Lp(a)] and risk of coronary artery disease (CAD) is well established, its role in risk of peripheral arterial disease (PAD) remains unclear. PAD affects over 236 million individuals and follows ischaemic heart disease (IHD) and cerebrovascular disease (CVD) as the third leading cause of atherosclerotic cardiovascular morbidity worldwide. LP (a) is genetically determined, stable throughout life and yet refractory to drug therapy. While 30 mg/dl is considered the upper normal value for LP (a) in central Europe, extremely high LP (a) levels (&gt;150mg/dl) are rare in the general population. The aim of our study was to analyse the correlation between lipoprotein (a) [LP (a)] levels and an incidence of PAD in high-risk patients. Patients and methods We reviewed the LP (a) concentrations of 52.898 consecutive patients admitted to our cardiovascular center between January 2004 and December 2014. Of these, 579 patients had LP (a) levels above 150 mg/dl (mean 181.45±33.1mg/dl). In the control collective LP (a) was &lt;30mg/dl (n=350). Other atherogenic risk factors in this group were HbA1c 6.58±1.65%, low density lipoprotein (LDL) 141.99±43.76 mg/dl, and body mass index 27.81±5.61. 54.40% were male, 26.07% were smokers, 93.2% had hypertension, and 24% had a family history of cardiovascular diseases. More than 82.6% were under statins. The mean glomerular filtration rate (GFR) was 69.13±24.8 ml/min [MDRD (Modification of Diet in Renal Disease)]. Results 45.00% (n=261) of the patients with LP (a) &gt;150mg/dl had PAD. The prevalence of PAD in patients with LP (a) &lt;30mg/dl in our control collective was 15.8%. (P- Value 0.001). Patients with LP (a) &gt;150mg/dl had a significantly increased risk for PAD (Odds ratio 4.36, 95% CI 2.94–6.72, p: 0.001). 19.1% of patients were re-vascularized by percutaneous angioplasty (PTA) and 7.09% of patients had to undergo peripheral vascular bypass (PVB). Mean LP (a) level in patients with PAD was 182.6±31.61. Conclusion Elevated LP (a) levels above 150 mg/dl are associated with a significantly increased risk of PAD in our collective and it confirms our hypothesis. Over one fourth of these patients had severe PAD and requiring revascularization therapy. We need more prospective studies to confirm our findings.

Sebagai mother of desease, penyakit DM memiliki komplikasi yang serius seperti retinopati diabetik, neuropati, amputasi, penyakit jantung, gagal jantung, stroke dan peripheral arterial disease. Kondisi tersebut menunjukkan perlunya keseriusan dalam penanganan penyakit DM. Diperlukan dukungan dari kader (sebagai bagian dari support group) bagi peserta prolanis DM. Tujuan penelitian ini adalah untuk mengetahui implementasi metoda support group dalam meningkatkan persepsi pasien tentang perawatan DM di Kota Bandung. Penelitian ini termasuk jenis penelitian kuantitatif dengan menggunakan rancangan quasi experiment dengan pretest and post test non equivalent control group. Hasil penelitian menunjukkan peningkatan persepsi pasien prolanis sebesar 3,08 dan peningkatannya dinyatakan sangat bermakna (p<0,01).  Edukasi yang dilakukan kader (support group) berpengaruh terhadap peningkatan persepsi pasien DM. Metode support group dengan memberdayakan kader dalam memberikan edukasi sangat bermanfaat dan dapat dijadikan kebijakan di pelayanan kesehatan masyarakat.

Introduction: The protective relation of high density lipoprotein-cholesterol (HDL-C) with coronary heart disease may be weakened in the presence of inflammation; however, whether inflammation may attenuate any association of HDL-C with peripheral arterial disease (PAD) is unknown. Hypothesis: We hypothesized that inflammation measured by high-sensitivity C-reactive protein (hs-CRP) will attenuate any inverse association of HDL-C with PAD. Methods: We studied 6512 men and women aged ≥ 40 years who participated in the National Health and Nutrition Examination Survey (NHANES ) from 1999-2004 who had measures of ankle brachial index (positive for PAD defined as <0.9 or ≥1.5), lipids, high-sensitivity CRP (hs-CRP) and other risk factors. Groups were categorized by low (<40 mg/dL for men or <50 mg/dl or women), intermediate (40 or 50-59 mg/dL), and high (≥60 mg/dL) HDL-C, and low (<1 mg/L), normal (1-3), and high (3 mg/L) hs-CRP levels. We evaluated the odds ratio (ORs) for PAD by logistic regression adjusted for age, race, gender, low density lipoprotein-cholesterol, smoking, diabetes, body mass index, systolic blood pressure waist circumference and triglycerides. Results: Those with the highest hs-CRP levels had the highest prevalence of PAD (8.5-10.8%), regardless of level of HDL-C (figure 1). Using high HDL-C/low hs-CRP as the reference, the likelihood of PAD was significantly increased among those with normal and high hs-CRP within the intermediate HDL-C group: OR 4.7 (95%CI 1.6, 14.1) and OR 4.5 (95% CI 1.4,14.2) , respectively. Among those with normal and high hs-CRP within the low HDL-C group, the likelihood of PAD was also increased:OR 5.0 (95% CI 2.1,12,1) and OR 6.4 (95% CI 2.2,18.1), respectively. Conclusion: High hs-CRP is associated with higher likelihood of PAD across all ranges of HDL-C, but especially when HDL-C is normal or low. These results support the value of combined hs-CRP and HDL-C in risk stratification for PAD which should be validated by prospective studies.
