Genomic test to guide diabetes heart and kidney care
This study is testing whether a special blood test (genomic predictor) can help doctors better manage heart and kidney risks in people with type 2 diabetes. You may benefit from learning your personal risk score and getting more tailored care.
Montreal, QuebecAges 18 years+ - NCT06586424Recruiting
Can Anion Gap Predict Heart Risks After a Heart Attack?
This study checks if a simple blood test measure (anion gap) can help predict serious heart problems in people who have had a major heart attack (STEMI) and received emergency angioplasty. It may help doctors better understand your risk and guide future care.
Semarang, Central of JavaAges 18–70 - NCT06586970Recruiting
Meals plus therapy to prevent falls for older adults
This study tests whether adding occupational therapy and dietitian services to home-delivered meals helps older adults stay safe and reduce falls. It's for people who are homebound, can't have a caregiver cook for them, and live in central Ohio.
Columbus, OhioAges 60 years+ - NCT06587165Recruiting
Measuring new heart cells in babies having heart surgery
This study looks at how the heart makes new muscle cells in babies under 1 year old who need heart surgery. Tissue that is normally removed during surgery will be studied to learn more about heart repair.
New York, New YorkAges 4 weeks–1 year - NCT06587204Recruiting
Digital study for heart health in Black and Hispanic adults
This study uses a smartphone app to help Black and non-White Hispanic adults with heart or blood sugar conditions. It aims to make research easier to join from home and understand why some groups don't participate.
Miami, FloridaAges 18 years+ - NCT06587308Recruiting
How pressure garments affect arm function after stroke
This study tests whether wearing special pressure garments on the arm can improve movement, feeling, and quality of life for people who have had a stroke. It may help if you have some arm weakness but not too much tightness or other health problems.
