Acute chest syndrome

This trial investigates whether continuous positive airway pressure (CPAP) can help adults with sickle cell disease recover faster from acute chest syndrome, a serious lung complication. Participants who need extra oxygen are randomly assigned to receive either standard oxygen al…

This trial tests whether a less intensive antiplatelet therapy is safer and as effective as standard dual therapy for people with spontaneous coronary artery dissection (SCAD), a rare cause of heart attack in women aged 30–55. Unlike typical heart attacks, SCAD involves a tear in…

This study tests whether dapagliflozin, a drug typically used for diabetes, can lower inflammation in the heart arteries of people who recently had a heart attack but do not have diabetes or heart failure. About 110 participants will receive either the drug plus standard care or …

This study tests whether a short course of the antibiotic rifaximin can improve how well the blood thinner ticagrelor works in people who have had a heart attack. The idea is that unhealthy gut bacteria may interfere with the drug, and clearing them out could help prevent future …

This study tests whether a bedside lung ultrasound, done within six hours of arriving at the emergency department, can help diagnose acute chest syndrome in adults with sickle cell disease experiencing a vaso-occlusive crisis. Acute chest syndrome is a serious lung complication t…

This study is testing a new tool called UFR, which uses ultrasound images to measure blockages in heart arteries during a heart attack. Currently, the most accurate method requires patients to return 30 days later for a second invasive procedure. The study will enroll 200 heart a…

This study tests whether awake prone positioning (lying on the stomach while awake) can help sickle cell patients with severe acute chest syndrome in the ICU. The approach aims to improve oxygen levels and breathing by evening out air flow in the lungs. Fifteen adults will be enr…

This study will follow 645 older adults (65+) who come to the hospital with a heart attack. Researchers want to see if frailty—a state of reduced strength and energy—affects how doctors treat them and whether they have serious problems like death or another heart event within 30 …
