Swan-Ganz catheter for cardiogenic shock after heart attack
This study tests whether a special catheter (Swan-Ganz) placed in the heart's blood vessels helps doctors better manage fluids and medications for people in cardiogenic shock after a heart attack. It aims to improve blood flow to vital organs.
HanoiAges 18 years+ - NCT07063043Recruiting
A study using a new scan to look at heart disease
This trial is testing a new imaging method (68Ga-FAPI PET/CMR) to better see and understand heart problems. It might help doctors diagnose or monitor conditions like heart failure or inflammation.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT07063147Recruiting
Heart ultrasound for stable chest pain management
This study uses a heart ultrasound (TTE) to help doctors better manage stable chest pain. If you have chest pain that may be from a blocked artery but haven't had a heart attack or heart procedures before, this trial could help improve your care.
