Active clinical trials for "Heart and Blood Diseases"

Evaluation of initial safety and clinical feasibility of the Viper Catheter System for thrombectomy in acute submassive pulmonary embolism (PE).

The purpose of this study is to evaluate the efficacy and safety of AD-209

This is a multi-center, prospective, propensity matched twin armed study conducted on 50 patients in the experimental arm followed for 18 months after intervention evaluating cost effectiveness, safety and efficacy of therapy.

Randomized Controlled Trial to determine if the outcomes of sclerotherapy of the ulcer bed alone differ from a combination of ablation and sclerotherapy injections.

The purpose of the present pilot study is to evaluate the feasibility and potential efficacy of a brief, internet-delivered CBT protocol provided early after acute coronary syndrome (ACS).

The purpose of this study is to evaluate the safety and efficacy of once daily oral inhalation dose of MK-5475 380 µg in participants 40 to 80 years (inclusive) with Pulmonary Hypertension associated with Chronic Obstructive Pulmonary Disease (PH-COPD). The primary hypothesis of the study is MK-5475, a soluble Guanylate Cyclase (sGC) stimulator is superior to placebo in increasing 6 Minute Walking Distance (6MWD) from baseline at Week 24.

Supervised exercise training (SET) is considered among first-line therapies for patients with symptomatic lower extremity peripheral artery disease (PAD), combined with general cardiovascular risk management, lifestyle adaptation and pharmacological treatment. Although without clear consistency, the guidelines give recommendations in terms of claudication pain severity, SET volume, duration, and frequency. However, no or little guidance is offered as far as training intensity is concerned. Most of the previous studies on SET, in the context of PAD, did not distinguish between symptom intensity and common training intensity measures such as % of maximal heart rate (%HRmax), % of HR reserve (%HRR), % of peak oxygen uptake (%VO2peak), % of VO2 reserve (%VO2R), or the rate of perceived exertion (RPE). In a recent meta-analysis, we demonstrated that both training modality and exercise intensity (based on %peak heart rate, %peak oxygen uptake, or the rate of perceived exertion) should be considered when looking for the best results in patients with symptomatic PAD. These results call for study of the individual roles of each exercise intensity and modality on walking performance and cardiorespiratory fitness in patients with symptomatic PAD. High-intensity interval training (HIIT) is composed of brief bursts of vigorous intensity interspersed with periods of rest or low-intensity exercise. HIIT may be better than moderate-intensity training (MIT) in improving cardiorespiratory fitness and functional capacity in patients with cardiovascular and metabolic diseases, but in patients with symptomatic PAD, the effects of such modalities on walking ability and cardiorespiratory fitness remain to be clearly determined. The primary objective of this study is to compare the effects of 12-week-long exercise training (short-duration high-intensity intervals vs. low-to-moderate intensity) on treadmill performance in patients with symptomatic PAD. It is hypothesized that treadmill performance would be improved to a greater extent after high-intensity exercise training

To evaluate the tolerability and safety of CAR-T technology in patients with relapsed or refractory hematolymphoid malignancies.

The aim of this study is to evaluate the therapeutic efficacy of uncultured adipose derived stromal vascular fraction (SVF) and cultured adipose derived stem cells (ASCs) both supplemented with platelet rich plasma (PRP) to treat chronic diabetic foot ulcers. It will increase the pragmatic potential of both types of cells as PRP is rich in survival and chemotactic factors. Moreover, the autologous nature of the proposed study will ensure safety of its use in diabetic patients and will unveil the more effective therapeutic option for treatment of foot ulcer wounds.

Researchers are looking for a better way to treat people who have chronic heart failure with reduced ejection fraction (HFrEF). HFrEF is a long-term condition where the left side of the heart does not pump blood out to the body as well as it should. Blood and fluid may collect in the lungs, blood vessels, and tissues causing shortness of breath or tiredness. Over time, heart failure can lead to other serious medical conditions that may result in hospital stays and death. Despite various available treatments for long-term HFrEF, people may experience worsening of their condition, called worsening heart failure events. Worsening heart failure events require the patient to either stay in the hospital or receive special treatment to remove excess water from the body. The drug vericiguat works by increasing the activity of an enzyme called soluble guanylate cyclase (sGC). The sGC enzyme helps to regulate the heart and blood circulation. Vericiguat was recently approved in India for doctors to prescribe to people with HFrEF after they had a worsening heart failure event, with a request to specifically gather information on vericiguat therapy in Indians. Therefore, the main purpose of this study is to learn more about how well vericiguat works in Indian people with HFrEF who receive vericiguat after a worsening heart failure event. Work well means to prevent: death due to heart and circulatory events, or hospital stays. Researchers will collect the number of participants treated with vericiguat who have either of this. To find out how safe vericiguat is, researchers will also collect the number of participants who have medical problems during the study. Doctors keep track of all medical problems, even if they do not think the adverse events might be related to the study treatments. The participants will take vericiguat as tablet by mouth and as prescribed by their doctors according to the local label. Each participant will be in the study for approximately 1 year including a screening period of up to 1 month. Up to 8 visits to the study site are planned. During the study, the study team will: check vital signs do physical examinations examine heart health using electrocardiogram ECG and if needed echocardiography take blood and urine samples
