This study compares two procedures—pulsed field ablation and cryoballoon ablation—for treating atrial fibrillation (an irregular heartbeat). About 104 people having their first ablation will be randomly assigned to one method. The goal is to see which technique creates better sca…

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

This study compares two types of pacemaker settings in people who need a pacemaker after a TAVI procedure (a minimally invasive heart valve replacement). The two methods are 'physiological pacing' (which tries to mimic natural heart activation) and standard 'right ventricular pac…

This pilot study tests whether using a noninvasive global mapping system to guide catheter ablation can improve outcomes for people with persistent atrial fibrillation. Thirty participants will receive standard pulmonary vein isolation plus personalized ablation of up to three ad…

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 program or standard care…

This study tests whether using a CPAP machine at night can help people with severe uncontrolled asthma who also have obstructive sleep apnea. Researchers will compare asthma control, lung function, and quality of life between those who receive CPAP plus lifestyle advice and those…

This study compares two ways to create an arteriovenous fistula (AVF) for dialysis in people with advanced kidney disease. The standard end-to-side method is being tested against a newer piggyback technique that may reduce blockages and failures. About 130 adults who need dialysi…

This study tests whether a newer pacemaker method (conduction system pacing) can better prevent heart muscle weakening compared to the standard method. Researchers will enroll 200 adults who need a pacemaker for a slow heart rhythm. The goal is to see which approach reduces the r…

This study tests whether using a special cough-assist device (MI-E) with optimized settings can remove more mucus from the airways of critically ill patients on breathing machines. Researchers will compare the amount of mucus suctioned after using optimized versus standard settin…

This study looks at how different types of electrical nerve stimulation affect leg strength in athletes with patellar tendinopathy (jumper's knee). Nineteen athletes will try three stimulation methods in separate sessions to see which one best improves quadriceps strength. The go…

This study tests a therapy called m-CIMT for people who recently had a stroke and have weakness in one arm. The therapy involves restraining the good arm and doing specific exercises with the weak arm to improve its use. Researchers will measure changes in arm function, daily act…

This study tests whether giving high-flow oxygen through special nasal prongs during a less-invasive heart valve replacement (TAVR) can prevent low oxygen levels and breathing complications. About 452 older adults undergoing TAVR under sedation will be randomly assigned to receiv…

This study tests whether a program combining exercise, nutritional advice, and psychological support can reduce fatigue in people with primary biliary cholangitis (PBC). 64 participants with moderate to severe fatigue will be randomly assigned to either the rehab program or stand…

This study is looking at whether a simple exercise test and other health factors can predict how well people recover after a procedure called TAVI, which replaces a narrowed heart valve. Researchers will follow 161 patients with severe aortic stenosis to see which factors before …

This study tracks the mental workload of anesthesia nurses during real surgeries at a hospital in Barcelona. Nurses fill out a short questionnaire three times per surgery to rate their mental, physical, and emotional demands. The goal is to see when they are most stressed and how…
