All recruiting trials (21)
-
Head-of-bed position after clot-removal stroke therapy
This study tests whether keeping the head of the bed flat (0 degrees) after thrombectomy improves recovery compared with a raised position in adults who had an ischemic stroke due to large vessel blockage.
-
Monitoring heart rhythm after noncardiac surgery
This study is testing if wearing a portable heart monitor for up to 14 days after noncardiac surgery can help find heart rhythm problems that are often missed, to improve care for patients.
-
Registry for Calcium Release Deficiency Syndrome
This study is trying to gather information about Calcium Release Deficiency Syndrome to better understand it and find the best ways to treat people with this heart condition caused by RYR2 gene changes.
-
Surgical procedure to prevent heart rhythm issues after cardiac surgery
This study is testing a surgical procedure to see if it can help prevent heart rhythm problems after heart surgery for patients who haven't had these issues before.
-
Using patients' own blood to reduce transfusion needs after heart surgery
This study is testing whether using patients' own blood during heart surgery can help reduce the need for blood transfusions compared to the usual method.
-
Evaluating a diagnostic test for Calcium Release Deficiency Syndrome
This study is testing a new way to diagnose Calcium Release Deficiency Syndrome by looking at how the heart responds to fast pacing, aiming to make diagnosis easier for patients with this condition and similar heart issues.
-
Short-term treatment with amiodarone for new atrial fibrillation after heart surgery
This study is testing whether a short-term treatment with amiodarone can help people who develop new atrial fibrillation after heart surgery feel better and keep their heart rhythm stable.
-
Assessing frailty to predict outcomes in older gynecologic cancer patients
This study is testing if checking for frailty before surgery can better predict recovery and complications for older women with gynecologic cancer compared to standard heart health checks.
-
Virtual care to improve recovery from heart failure hospitalization
This study tests whether virtual follow-up visits can help people recovering from heart failure hospitalization feel better compared to regular in-person care.
-
Reducing mortality in adults with advanced HIV disease using azithromycin
This study is testing if taking azithromycin can help adults with advanced HIV live longer by comparing it to a placebo.
-
Bariatric surgery to reduce cardiovascular events in obese patients
This study tests if bariatric surgery can help people with severe obesity and heart disease lower their risk of serious heart problems better than just medical weight management.
-
Surgical ablation for treating atrial fibrillation during heart surgery
This study is testing if a surgical procedure to treat atrial fibrillation during heart surgery can help patients have better heart health and lower their chances of stroke and heart failure compared to standard care.
-
Virtual care and remote monitoring after surgery
This study tests if using virtual care and remote monitoring after surgery can help patients recover better and avoid complications compared to regular follow-up care.
-
Using low dose colchicine to reduce vascular events in patients with peripheral artery disease
This study is testing if a low dose of colchicine can help people with peripheral artery disease avoid serious heart and leg problems compared to a placebo.
-
Accelerated surgery for hip fractures in patients with heart injury
This study is testing if faster surgery for hip fractures can help people with heart injuries live longer and recover better compared to standard care.
-
Continuing HER-2 therapy in patients with heart dysfunction
This study is testing if people with early-stage HER-2 positive breast cancer and mild heart issues can safely continue their HER-2 treatments while taking heart medications, instead of stopping their cancer treatment.
-
Comparing two types of blood thinners after heart surgery
This study is testing which type of blood thinner is safer for people who have had heart surgery and need it to prevent strokes from atrial fibrillation.
-
Comparing higher and lower doses of heparin for heart procedures
This study is testing whether using a higher dose of heparin during heart procedures helps patients do better than using a lower dose.
-
Preventing strokes in patients with recent atrial fibrillation after noncardiac surgery
This study is testing whether a new type of blood thinner can help prevent strokes in patients who had temporary heart rhythm issues after non-heart surgery.
-
Lowering INR targets to reduce bleeding in patients with mechanical heart valves
This study is testing if setting a lower blood clotting target for patients with mechanical heart valves can help reduce bleeding risks without causing more blood clots or strokes.
-
Examining health determinants and their impact on chronic diseases
This study looks at how personal choices and community factors affect heart health and other long-term illnesses to see what really impacts people's health.
