This study compares two types of heart pacing—conduction system pacing and standard biventricular pacing—in 320 adults with heart failure and a wide QRS. The goal is to see which method better reduces the risk of death, heart failure hospitalization, or need for a heart transplan…

This study tests whether a program of physical exercise, nutritional guidance, and psychological support during chemotherapy can help women with early-stage breast cancer respond better to treatment. About 214 women will be randomly assigned to either the lifestyle program or sta…

This study compares two types of ablation (pulsed field vs cryoballoon) for people with atrial fibrillation, a heart rhythm problem. About 104 participants will be randomly assigned to one of the two methods. The main goal is to see which technique creates better scar tissue arou…

This study looks at people who need a pacemaker after having a new heart valve placed (TAVI). It compares two pacing methods to see which one helps the heart pump better and improves daily activities like walking. About 48 participants will be followed for 12 months to measure he…

This study compares two surgical techniques for creating arteriovenous fistulas (AVFs) needed for hemodialysis in people with advanced chronic kidney disease. The standard end-to-side method is being tested against a newer piggyback technique that may reduce complications like na…

This study tests a newer pacing method (physiological pacing) against the standard method to see if it can prevent pacemaker-induced heart damage. About 200 adults who need a pacemaker for a slow heartbeat will be randomly assigned to one of the two methods. The goal is to reduce…

This study tests whether a gentle brain stimulation technique called tDCS, combined with health education and aerobic exercise, can reduce severe tiredness after a stroke. About 54 adults who had a stroke within the last 45 days and feel very fatigued will take part. The goal is …

This study tests a non-drug program of exercise, nutrition advice, and psychological support to reduce fatigue in people with primary biliary cholangitis (PBC). About 64 adults with moderate to severe fatigue will join. The goal is to see if this approach improves tiredness, qual…

This study looks at how different types of electrical nerve stimulation affect leg strength in athletes with patellar tendinopathy, also known as jumper's knee. Nineteen athletes will try three stimulation methods in separate sessions to see which one best improves their quadrice…

This study tests a therapy called m-CIMT for people who recently had a stroke and have arm weakness. The treatment involves restricting the unaffected arm while doing exercises with the affected arm to improve its function and daily use. Researchers will enroll 66 hospitalized pa…

This study tests whether high-flow nasal oxygen (HFNO) can prevent low oxygen levels and breathing complications during a minimally invasive heart valve replacement (TAVR) compared to standard oxygen. About 452 adults undergoing TAVR under sedation will be enrolled. The goal is t…

This study tests a personalized approach to treat atrial fibrillation (AFib) using a special mapping system to guide a heart procedure called catheter ablation. The goal is to see if this tailored method works better than the standard approach at stopping AFib and preventing it f…

This study looks at whether using a CPAP machine at night can improve asthma control in adults with severe, hard-to-control asthma and obstructive sleep apnea. Researchers will measure asthma symptoms and lung function in 138 participants over time. The goal is to see if treating…
