BACKGROUND: In the pathogenesis of peripheral arterial occlusive disease (PAD), different risk factors of atherosclerosis are involved which stimulate the development of the functional and morphological deterioration of vessel walls in macro- and microcirculation. The endothelial dysfunction (ED) of macrovessels has been proven, however, data on ED in microcirculation are sparse. Therefore, we have studied the relationship between micro- and macrocirculation in PAD patients. PATIENTS AND METHODS: The study included 85 participants: 30 patients had PAD without diabetes mellitus, 30 patients had PAD and diabetes mellitus type 2, and 25 were healthy controls...

INTRODUCTION: The endothelial function plays key roles in both promoting and protecting against atherosclerotic disease. Several methods, including peripheral arterial tonometry (PAT), have been reported to be useful for investigating endothelial dysfunction. Furthermore, the level of thrombomodulin (TM) is assumed to reflect the endothelial dysfunction. In the present study, we investigated endothelial dysfunction in patients with peripheral arterial disease (PAD) by measuring their TM levels, and evaluated the correlation between TM and various parameters...

Atherosclerosis is one of the major causes of death. Data from animal experiments suggest that atherosclerosis involves an inflammatory process of the vascular wall under hyperlipidemia. Atherothrombosis can become a serious complication of atherosclerosis leading to acute cardiovascular events such as myocardial infarction and stroke. Clinical applications to use this knowledge remain scarce. The plasma levels of vascular endothelium-enriched microRNA (miRNAs) in patients with atherosclerotic vascular disease could serve as a disease marker...
