Acute coronary syndromes (ACS)

Researchers are studying how heart arteries change after a blocked vessel is opened with a paclitaxel drug-coated balloon instead of a metal stent. The balloon delivers a drug to the artery wall and then is removed, leaving no permanent implant. About 150 adults who had this proc…

This trial tests whether starting a powerful cholesterol-lowering combination right after a heart attack can make the fatty plaques in coronary arteries more stable. Researchers will compare an early intensive strategy using a high-intensity statin, ezetimibe, and inclisiran agai…

This trial tests whether a hybrid cardiac telerehabilitation program — combining in-person sessions, live video workouts, and remote monitoring — can improve adherence to exercise rehab in people with coronary artery disease or stable heart failure. Participants are randomly assi…

This study looks at whether icosapent ethyl, a purified fish oil medication, can reduce inflammation and improve heart structure in people with coronary artery disease. Researchers will follow 420 patients for one year, comparing those who receive standard care plus icosapent eth…

This study tests whether a new wire-free imaging method called μFR can help doctors decide which blocked heart arteries need stents after a heart attack. About 350 patients with multiple blocked arteries will be randomly assigned to standard care or μFR-guided treatment. The goal…

This study compares a three-drug combination (atorvastatin, ezetimibe, and bempedoic acid) against the usual two-drug therapy for lowering LDL cholesterol in people who have had a heart attack or unstable angina. About 120 adults will take either the triple or dual therapy for 3 …

This study compares two types of drug-coated balloons used to open blocked heart arteries in people with acute coronary syndrome (a serious heart condition). About 60 adults will receive either a sirolimus-coated or paclitaxel-coated balloon. The main goal is to see which balloon…

This study tests whether adding visits with a nurse, dietitian, and pharmacist to standard care helps more heart attack patients reach their LDL (bad) cholesterol goals. About 230 adults who had a recent heart attack will be randomly assigned to usual follow-up or extra team-base…

Researchers are testing whether a non-invasive device that reads the heart's magnetic signals can help emergency department doctors tell high-risk from low-risk chest pain. The study enrolls adults 22 and older who arrive with symptoms suggesting a possible heart attack and who f…

This trial tests whether guided imagery, a relaxation technique using audio recordings, can reduce anxiety and improve sleep and comfort in adults with acute coronary syndrome, such as a heart attack, who are in a cardiac intensive care unit. Participants will be randomly assigne…

This study tests whether using a CT scan to plan a heart stent procedure (PCI) makes it faster, safer, and more effective than the usual approach. About 200 adults with coronary artery disease will either get CT-guided planning or standard care. Researchers will compare procedure…

This study will check if a routine blood measure called mean platelet volume (MPV) can predict acute coronary syndrome (heart attack or unstable angina) in people with metabolic dysfunction-associated steatotic liver disease (MASLD). Researchers will compare MPV levels between 60…

This study will look at health records of 10,000 patients in Qatar who were hospitalized for heart problems and have diabetes or prediabetes. Researchers will use artificial intelligence to find patterns that predict future heart attacks, strokes, or death. The goal is to create …
