ST-elevation myocardial infarction

This early-phase trial tests whether a single dose of donor stem cells (OmniMSC-AMI) given directly into the heart arteries is safe for people who have just had a major heart attack. The study enrolls adults aged 20–80 with a specific type of heart attack (anterior STEMI) who are…

This study tested an intravenous antiplatelet drug called PRT060128 in 70 people having a severe heart attack (STEMI). The goal was to see if giving the drug before emergency artery-opening treatment improved blood flow and was safe. The trial was terminated early, so the full re…

This study tested whether giving extra oxygen directly to the heart for 60 minutes after angioplasty could improve outcomes for people having a major heart attack. Only 17 patients were enrolled before the study was stopped early. The goal was to see if this oxygen therapy could …

This study looked at whether giving a powerful cholesterol-lowering drug (evolocumab) very early after a major heart attack could help the heart pump better and prevent long-term damage. About 119 adults who were having a heart attack and scheduled for a procedure to open blocked…

This study looked at whether using two types of 'ischemic conditioning' (brief cycles of blood flow restriction and release) could improve outcomes for people having a major heart attack. One method used a blood pressure cuff on the arm, the other used a balloon inside the heart …

This phase 2 trial tested whether using ultrasound and microbubbles (sonothrombolysis) alongside standard clot-busting drugs could help restore blood flow in people having a severe heart attack. The study planned to enroll 41 participants but was terminated early. The main goal w…

This completed study looked at whether stomach emptying is slower during a heart attack, which could delay the absorption of crucial antiplatelet drugs. Researchers measured paracetamol levels in the blood every 15 minutes in 23 participants to track stomach emptying. The goal wa…

This study aimed to understand why some people develop heart failure after a heart attack. Researchers used special PET scans and blood tests to measure blood vessel function and scarring in the heart muscle of 30 patients who had a first heart attack. The goal was to see if thes…

This study looked at whether an early heart MRI can help doctors know which patients with severe heart damage after a heart attack will get better on their own. The goal was to see if MRI could identify patients who would benefit from getting a defibrillator sooner rather than wa…
