This study aims to find the best way to guide a repeat procedure when a previously placed heart stent gets blocked again. It will compare using standard X-ray images (angiography) against more detailed internal imaging (IVUS) to see which method leads to better long-term results …

This study is comparing two different tools doctors can use to crack open hardened, calcified plaque in heart arteries before placing a stent. One tool is a super high-pressure balloon, and the other uses sound waves (intravascular lithotripsy). The main goal is to see which meth…

This study is looking at whether treating a common stomach infection (H. pylori) can help improve related health issues like high blood sugar and cholesterol. Researchers will also test if adding probiotics or a natural supplement (berberine) to the standard treatment makes these…

This large study is testing whether adding a low-dose anti-inflammatory drug called colchicine to standard heart medications can better prevent serious heart problems. It will involve about 3,800 adults with stable coronary artery disease who have plaque buildup in their arteries…

This study is testing if a new laser-assisted ultrasound method helps nurses place IV lines more successfully on the first try in patients having heart surgery. It compares the new method, which uses a laser to guide the needle, to the standard ultrasound technique. The goal is t…

This study is testing new types of imaging scans to better find and map rare nerve and adrenal tumors (neuroblastoma and pheochromocytoma/paraganglioma). Researchers will give participants special tracer injections and use PET or SPECT scans to see if these new methods can spot t…

This study aims to find the perfect amount of a long-acting numbing medicine to use for pain relief after knee surgery. Researchers are testing different volumes on 63 adults having knee surgery to see which one provides the best pain block with the least impact on leg muscle str…

This study aims to learn which of two nerve-block injection techniques works better for numbing the chest during a lung nodule biopsy. Researchers will compare how far the numbing medicine spreads and how well it blocks pain for 50 patients. They will use CT scans to create 3D pi…
