Dyslipoproteinemia and Peripheral Arterial Occlusive Disease

Selected Atherosclerosis-Related Diseases May Differentially Affect the Relationship between Plasma Advanced Glycation End Products, Receptor sRAGE, and Uric Acid

Our study aimed to identify the relationship between advanced glycation end products (AGEs), soluble receptor for advanced glycation end products (sRAGE), the AGEs/sRAGE, and uric acid (UA) levels in selected atherosclerosis diseases, i.e., abdominal aortic aneurysms (AAA), aortoiliac occlusive disease (AIOD), and chronic kidney disease (CKD), resulting from apparent differences in oxidative stress intensity. Furthermore, we suggest that increased AGEs levels may stimulate an antioxidant defense system reflected by the UA level. The studied group size consisted of 70 AAA patients, 20 AIOD patients, 50 patients in the pre-dialyzed group (PRE), and 35 patients in the hemodialyzed group (HD). The enzyme-linked immunosorbent assay was used to measure AGEs and sRAGE levels. We found a significantly higher concentration of AGEs in CKD patients as compared to AAA and AIOD patients. Furthermore, the sRAGE level was higher in the CKD patients in comparison to AIOD and AAA patients. UA level was significantly higher in the PRE group compared to AAA patients. In conclusion, the diseases included in this study differ in the anti- and prooxidant defense system, which is reflected in the relations between the AGEs, the sRAGE, the AGEs/sRAGE ratio, as well as the UA levels.

A Comparison of Aortoiliac Disease between Eastern and Western Countries

A variety of diseases are known to develop in the aortoiliac segment; these include abdominal aortic aneurysm (AAA) and aortoiliac occlusive disease. This review summarizes several differences of aortoiliac diseases between eastern and western populations. The prevalence of AAA was higher in western countries (4.57% to 19%) than in eastern countries (0.89% to 4.9%). Greater aortic bifurcation angles were observed in the eastern population, while longer common iliac arteries and aneurysm necks were found in the western population with AAA. However, the angle of the aneurysm was found to be more acute in patients from western countries. Several differences were found between patients from western countries and those from eastern countries regarding the diseases that occur in the aortoiliac segment and their anatomical characteristics. Therefore, different approaches to the treatment of aortoiliac diseases in these two groups should be considered.

Risk factors in abdominal aortic aneurysm and in Polish population aortoiliac occlusive disease and differences between them [corrected]

Abdominal aortic aneurysm (AAA) and aortoiliac occlusive disease (AIOD) are multifactorial vascular disorders caused by complex genetic and environmental factors. The purpose of this study was to define risk factors of AAA and AIOD in the Polish population and indicate differences between diseases.

Prescribing Practice of General Practitioners in Northern Ireland for Peripheral Arterial Disease

Peripheral arterial disease is prevalent and reflects overall cardiovascular disease state. Best medical treatment is the cornerstone of management to reduce peripheral arterial disease symptoms and to minimize vascular morbidity and mortality. The aim of this study was to assess the prescription practice of general practitioners in Northern Ireland for patients with peripheral arterial disease. All general practitioners were from the Northern Ireland Professional Medical Directory, and a questionnaire was used to determine the prescribing patterns for peripheral arterial disease. In all, 468 general practitioners responded; 94% prescribed aspirin to nondiabetic patients, and 44.9% prescribed statin, with similar results for diabetic patients. Angiotensin-converting enzyme inhibitors, multivitamins, and β-blockers were not often prescribed. Statin was prescribed to patients with diabetic peripheral arterial disease at a lower cholesterol concentration. In all, 52% would consider statin and fibrate together. Budgetary consideration influenced 6%. Northern Ireland general practitioners are reluctant to prescribe medication that is effective in the secondary prevention of vascular morbidity and mortality in high-risk patients.

Statins and Peripheral Arterial Disease: Potential Mechanisms and Clinical Benefits

Peripheral arterial disease (PAD) is a manifestation of widespread atherosclerosis. Lipid modification (especially with statins) is a component of the treatment of patients with PAD since this condition is considered a coronary heart disease equivalent. This review considers the mechanism of action of statins in PAD. Statins have been shown to reduce the incidence of new coronary events in patients with PAD. However, surveys suggest that many such patients remain undertreated. Statins can also increase walking distance in patients with PAD. There is also evidence that statins can improve renal function in these patients. Several other actions of statins are considered in this review. PAD patients have an increased morbidity and mortality, largely due to myocardial infarction and stroke. Recognizing and treating these high-risk patients as early as possible should be a priority.
