Filter by:In order to assessment the safety and efficacy of debulking atherectomy versus stent angioplasty for limb ischaemia of diabetic lower limb atherosclerosis-occlusive disease, we intend to conduct a prospective, multicenter, randomized controlled, non-inferiority trial. The main surgical methods included stent angioplasty group (Nickel-titanium self-expanding bare stent) and debulking atherectomy group (Excimer laser atherectomy combined with drug-coated balloon angioplasty). The sample size was 244 patients, and the patients were followed up at 30 days, 180 days, and 365 days after operation.
Objective: To evaluate the impact of heated versus combustion tobacco products on progression of atherosclerosis in patients with CAD unable(unwilling) to quit smoking. Rationale: Despite the efforts to curb smoking and full awareness of its deleterious health impact, smoking remains a significant contributor to morbidity and mortality. Some health impact of smoking may be improved by other forms of cigarettes than traditional combustion, especially for subjects unwilling or unable to stop smoking. As recently as 2020, one of heated tobacco products (HTP)(IQOS) was FDA Authorized as a 'Reduced Exposure' product. The available evidence to date allows to conclude that the IQOS system heats tobacco but does not burn it, which significantly reduces the production of harmful and potentially harmful chemicals. Scientific studies have shown that switching completely from conventional cigarettes to the IQOS system significantly reduced body's exposure to harmful or potentially harmful chemicals. There is also evidence indicating lower levels of inflammatory markers and improved vascular function associated with use of heated tobacco products. However, it is unknown whether the reduction in the exposure translates into potential reduction of harm within cardiovascular system, as compared to the traditional (combustion) cigarettes. The evidence is of crucial importance for patients with cardiovascular diseases, medical community, and national health authorities planning evidence based policies regarding HTP/cigarettes.
Guideline recommended evidence-based clinical care correlates with improved patient outcomes. In real life care, however, adherence to guideline recommendations remains suboptimal. In real life, patients may receive suboptimal treatment and as a result treatment targets are not always met. To support and improve secondary prevention for cardiovascular disease, PENELOPE and PENELOPE-CTRL are designed to support guideline implementation on lipid management and provide valuable feedback to care-givers on real world data.
The goal of this study is to determine the relationship of apoprotein A-1 (apoA-I) glycation and development of diabetic atherosclerosis. ApoA-I is crucial for reverse cholesterol transport and anti-inflammation/anti-atherosclersis functions of HDL. However, apoA-I is easily subjected to non-enzymatic glycation modification in diabetic milleu. Our preliminary study has shown that apoA-I in HDL from type 2 diabetes mellitus (T2DM) patients with coronary artery disease (CAD) is significantly glycated, and site specific glycation of apoA-I impairs HDL function and is related to the development of atherosclerosis. To the best of our knowledge, less clinical information regarding apoA-I glycation and CAD has been reported. In this cross-sectional study, by consecutively enrolling diabetic patients with (two to three hundred) or without CAD (controls, six to eight hundred) in our hospital, we will isolate their serum HDL and perform a qualitative and quantitative proteomic analysis of apoA-I glycation. The relation of apoA-I glycation and HDL function and angiography-determined severity of CAD will be evaluated. Later, we will follow these diabetic patients to analyze the influence of apoA-I glycation on the outcome including plaque progression.
In this proposal, the investigators will demonstrate the feasibility and noninferiority of telerobotic ultrasonography as compared to traditional manual acquisition in performing a limited carotid Duplex examination and in carotid plaque detection.
The overall objective is to evaluate the efficacy of educational text messages to reduce cardiovascular risk among persons living with HIV (PLWH).
The goal of this cross over study is to investigate the effect of short term time restricted eating (TRE) on the innate immune system in patients with a history of myocardial infarction.
Lipid accumulation, with mostly emphasized role of low-density lipoprotein cholesterol (LDL-C), is the pathogenetic cornerstone of atherosclerotic cardiovascular disease. Standard hypolipidemic therapy, based on statins and ezetimibe, does not always decrease LDL-C levels enough to achieve therapeutic goals. A novel and promising direction is inhibition of proprotein convertase subtilisin/kexin type 9 (PCSK9) in hepatocytes, subsequently reducing LDL-C receptor degradation and increasing intracellular LDL-C uptake. Aim of this study is to evaluate the effect of optimal hypolipidemic pharmacotherapy, including PCSK9 inhibitors and inclisiran, on plasma lipid profile and qualitative features of atherosclerotic plaques in very-high cardiovascular risk patients. This study enrolls patients with an established atherosclerotic cardiovascular disease, receiving PCSK9 inhibitors or inclisiran as add-on treatment to statins in maximally tolerated dose and/or ezetimibe. Effect of hypolipidemic pharmacotherapy is evaluated by analysis of plasma lipid profile parameter changes and qualitative features of atherosclerotic plaques using Near-Infrared Spectroscopy Intravascular Ultrasound Imaging (NIRS-IVUS) method. Results of the study would be sufficient for complementing evidence regarding therapeutic strategy in very-high cardiovascular risk patients.
The aim of this study was to determine the diagnostic accuracy of MR-FFR to detect functionally significant ICAS comparing with pressure-wire-based FFR.
The present study aims to examine the clinical practice of modifying the dose of lipid-lowering therapy in patients with atherosclerotic cardiovascular disease (ASCVD), who have LDL-C > 70 mg/dl despite statin treatment.
