A multi-omics study for blood cancers
This study is testing whether a complete platform that analyzes multiple molecular levels (multi-omics) can be used to better understand and diagnose blood cancers (hematological malignancies). It looks at samples from the blood, bone marrow, and tissues to help with initial diagnosis or when cancer returns after treatment.
Parma, PRAges 2 years+ - NCT07453251Recruiting
Tracking aortic strength for aneurysm surgery patients
This study tracks how the thickness of the aortic wall relates to strength in people having surgery for an aortic aneurysm. It aims to better understand the condition and possibly improve future care.
San Donato Milanese, MIAges 18 years+ - NCT07452276Recruiting
AI brain training for stroke recovery
This trial tests a computerized brain-training program that uses artificial intelligence to help people with memory problems after a stroke. If you are between 45 and 60 and had a stroke at least 3 months ago, you may be able to join.

Glycocalyx and stress in blood vessel function (Part 2)
This study looks at how a protective layer inside your blood vessels (the glycocalyx) and oxidative stress affect blood vessel function after heart bypass surgery. The goal is to better understand why some people recover differently.
OsijekAges 18 years+ - NCT07451457Recruiting
Structured education program for heart failure patients
This trial tests if a structured education program helps people with heart failure manage their condition better. If you have been hospitalized for heart failure or are treated at a heart failure clinic, you may be able to join and learn more about your care.
BudapestAges 18 years+ - NCT07451028Recruiting
Mouth training device for swallowing problems after stroke
This trial tests a device that strengthens mouth muscles to help people who have trouble swallowing after their first stroke. It may improve your ability to swallow safely.

This trial studies a new way to help people with high blood pressure get better control of their numbers. It uses a team approach to support you in managing your blood pressure and lowering your risk for heart problems.
Peoria, IllinoisAges 18 years+ - NCT07444931Recruiting
Predicting cardiac arrest risk in heart disease patients
This study looks at factors that may help predict sudden cardiac arrest in people with coronary artery disease. If you have a recent diagnosis of significant blockage or a heart attack, joining this trial could help improve risk assessment.

Comparing electrical stimulation and mirror therapy for foot drop after stroke
This trial compares two treatments—electrical stimulation and mirror therapy—to help people who had a stroke within the last 6 months lift their foot better when walking. The goal is to improve foot clearance and reduce trips or falls.
Lahore, Punjab ProvinceAges 18–85 - NCT07448779Recruiting
A study on N-glycosylation and its role in AL amyloidosis
This research study looks at how certain sugar molecules (N-glycosylation) on proteins may play a role in a disease called AL amyloidosis. Researchers will study blood samples from people with related plasma cell disorders to learn more about these sugars, which could help with diagnosis and treatment.
Pavia, PVAges 18–99 - NCT07445204Enrolling by invitation
Electrical stimulation for swallowing after stroke
This trial tests whether a gentle electrical stimulation technique on neck muscles can help improve swallowing in people who recently had a stroke. It may be a good option if you are still having trouble swallowing after your stroke.
IstanbulAges 18 years+ - NCT07448181Recruiting

Catheter ablation vs. medications for frequent extra heartbeats
This study compares two ways to treat premature ventricular contractions (extra heartbeats that can cause symptoms). One approach is a catheter ablation (a procedure that destroys the tissue causing the extra beats), and the other is using anti-arrhythmic drugs (medications to control the rhythm). If you have frequent PVCs and a healthy heart, this trial could help you find the best treatment.
