Filter by:Salvaging a threatened limb is the key therapeutic objective for patients with critical limb ischemia, and the achievement of limb salvage is an independent predictor of patient morbidity and mortality. Despite successful primary endovascular or surgical intervention, the corresponding symptoms of rest pain and/or non-healing ulceration in some patients may continue, and amputation in these patients is unavoidable. It is hypothesized that the functional integrity of the peripheral vascular microcirculation may be impaired in these patients. However, there are currently no techniques that allow direct quantification and visualization of the microcirculation due to the micro-vessel invisibility under angiography. In the coronary circulation, coronary flow reserve (CFR) indicates the capacity for maximal hyperemic blood flow and reveals impaired coronary microvascular function. Studies have shown the clinical significance of measuring microvascular resistance to predict myocardial salvage after myocardial infarction. The study will explore whether this concept of coronary flow reserve can be applied peripherally to patients with critical limb ischemia in order to determine whether measuring peripheral vascular flow reserve can determine the integrity of the microcirculation to predict limb salvage after endovascular intervention.
The purpose of the study is to determine associations between fitness status, bacteria in the mouth, and the blood flow to muscle. This study is trying to find out if fitness status impacts the bacteria that are present in the oral microbiome (environment in the mouth) or the ability of the body to send blood to the skeletal muscle. Participants will complete all or some of the following: - A mouth swab to assess the bacteria in their mouths. - Produce a saliva sample into a tube. - Cycle on a bike until you reach maximum effort. - Undergo blood draws - Wear a 24-hour non-invasive device that monitors blood pressure. - Undergo a test to assess blood flow to the muscles measured with an ultrasound. - Drink 70mL (1/3 of a cup) of concentrated beetroot juice once
Peripheral artery disease (PAD) is a cardiovascular disease manifesting from systemic atherosclerosis, which blocks the leg arteries and results in insufficient blood flow to the lower extremities. Limb ischemia from PAD is the most common disorder treated within the vascular surgery service at the Omaha Veterans' Affairs Medical Center. PAD also accounts for one-third of the operations performed in the VA Medical Centers nationwide. This project aims to establish the feasibility and acceptability of a muscle oxygen-guided supervised exercise program for patients with PAD. The investigators will determine the potential benefits of using this intervention over standard supervised exercise therapy. This modified intervention may enable patients to increase overall physical activity without the negative impacts on muscle structure and function. Increasing physical activity will decrease cardiovascular morbidity and mortality. If proven beneficial, the findings will lead to an improved exercise program that directly benefits veterans nationwide.
This randomized controlled study aimed to determine the effect of foot reflexology on pain and ankle brachial index level in patients with peripheral artery disease
The Global Vascular Guideline on chronic limb threatening ischemia (CLTI) proposes the Global Limb Anatomic Staging System (GLASS), a new angiographic scoring system to quantify the anatomic severity of infrainguinal disease in CLTI patients. However, GLASS validation still needs to be completed, and the infrapopliteal (IP) target artery pathway (TAP) was easily influenced by the procedures. Thus the IP target artery could be selected either as the least diseased artery based on angiography or prospectively based on the angiosome concept. So the investigators aim to evaluate its correlation with clinical outcomes after revascularization.
The purpose of this research is to find out if using liposomal bupivacaine solution (bupivacaine liposome) injections during lower extremity revascularization surgery will lower the amount of narcotic drugs used during and following the procedure.
The purpose of this study is to evaluate whether PET/CT-RGD or MIBI can be used for the angiogenesis assessment of NL003 in PAD patients.
The RESPONSE-2- peripheral arterial disease (PAD) program will be implemented to modify sedentary time in patients with PAD. It is an adapted version of the RESPONSE that aims to reduce sedentary behavior in individuals with diabetes. The RESPONSE-2-PAD is a multicomponent program involves an online educational component, sedentary reminders and health coaching sessions, which are designed to modify patients' sedentary behavior.
The CLIMATE Observational Study examines to what extent chronically ill patients experience adverse health effects because of heat and whether the patients' specific efforts, somatosensory amplification, self-efficacy, health literacy and commitment to the GP, degree of urbanisation of the patients' administration district and characteristics of the patients' neighborhood are associated with these effects.
Determination of IRTI (infrared thermal imaging) can be used to evaluate PAD patients with critical limb ischemia with different degrees of lesion. IRTI can be used to evaluate the foot blood perfusion after percutaneous transluminal angioplasty (PTA) treatment and determine the success rate of surgery. IRTI can be used as an effective follow-up tool for patients after surgery.
