Impella heart pump in heart attack with shock
This study looks at how well the Impella CP heart pump works for people who have a severe heart attack that causes their heart to pump too weakly to keep blood flowing to their body. It's a registry that follows your care to improve best practices.
Jonesboro, ArkansasAges 18 years+ - NCT02851758Recruiting
Autologous mitochondria treatment for critically ill heart children on ECMO
This trial looks at giving a child their own mitochondria to help protect the heart from injury caused by reduced blood flow. It is for children with serious heart problems who are on a heart-lung machine and may have signs of ischemia (reduced blood flow damage).
Boston, MassachusettsAges Up to 17 years - NCT05625373RecruitingPhase 2/Phase 3
Antibiotic powder during groin surgery to prevent infection
This trial studies whether placing an antibiotic powder (vancomycin) directly in the surgical wound during groin lymph node surgery can lower the risk of surgical site infections. It may help reduce wound infections after surgery for vulvar dysplasia.
Providence, Rhode IslandAges 18 years+ - NCT02493478Recruiting
Improve safety during placing breathing tubes in children
This trial looks at ways to improve the safety and quality of emergency breathing tube placement in pediatric critical care and emergency settings. It may help reduce complications and improve how clinicians do these urgent procedures.
Birmingham, AlabamaAges Any age - NCT05303363Recruiting
Checking brain blood flow during a breathing heart-lung machine
This study monitors how much blood is reaching the brain in adults who need a specific type of life-support called VV-ECMO. The goal is to better understand brain blood flow and how monitoring may help manage care during ECMO.
Amsterdam-ZuidoostAges 18–100 - NCT03475498Recruiting
ECG and heart ultrasound before and after pacemaker implantation
This study looks at how heart test results—electrical tracing (ECG) and heart ultrasound (echocardiogram)—change after a device is implanted. It may help doctors better predict who develops PICM (a certain pacing-related heart weakening) and how that affects outcomes.
ChungjuAges 20 years+ - NCT07174141Recruiting
Heart risks from newer blood cancer drugs (acalabrutinib or zanubrutinib)
This study looks for early signs of heart problems in people taking newer targeted blood cancer drugs called acalabrutinib or zanubrutinib. By using special blood tests, doctors hope to catch and manage heart issues before they become serious.

Comparing IV catheter lengths for hard-to-find veins in cancer patients
This trial compares two different lengths of IV catheters placed with ultrasound help for cancer patients in the emergency room who have hard-to-find veins. The goal is to see which catheter length works best and lasts longer during a hospital stay.
Houston, TexasAges 18 years+ - NCT07657364Recruiting
Comparing zirconia vs titanium for full-arch dental implants
This study compares two types of material (zirconia or titanium) used as a frame in full-arch screw-retained implant bridges. It aims to find which material has fewer complications, helps patients who have lost all teeth in one or both jaws.
CairoAges 18–70 - NCT06533592Recruiting
Bile duct connection technique in liver transplant
This study compares two ways of connecting the bile duct during a liver transplant to see which leads to a smoother recovery. It is for adults having a planned first transplant from a deceased donor.
Warsaw, Masovian VoivodeshipAges 18–75 - NCT06339671Recruiting
Recovery after surgery: smoking and complications
This study looks at how smoking habits affect recovery after colorectal surgery. It aims to understand if smokers have more complications than non-smokers, which could help tailor care before and after surgery.
MilanAges 18 years+ - NCT06422273Enrolling by invitationPhase 3
TXA vs Saline to Prevent Bleeding After Lung Transplant Biopsy
This trial tests whether a medication called tranexamic acid (TXA) can help prevent bleeding after a lung transplant biopsy. It compares TXA to a saltwater solution (saline) to see if it reduces the need for procedures to stop bleeding.
Grand Rapids, MichiganAges 18 years+ - NCT03004547Recruiting
MRI study of salt buildup in people with kidney problems
This study uses MRI scans to measure how much salt (sodium) builds up in soft tissues in people with kidney disease and related heart conditions. It may help researchers understand what’s happening in the body and how treatment or changes in care affect salt buildup.
London, OntarioAges 6 years+ - NCT06398977Recruiting
Dapagliflozin to protect kidney function in dialysis patients
This trial tests whether a diabetes drug called dapagliflozin can help people on peritoneal dialysis keep their remaining kidney function longer. It is for patients who started dialysis recently and still make urine.

Common questions
- Are there clinical trials for complication?
- Yes. Clin2 currently lists 1,145 recruiting complication studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a complication trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a complication trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
