MYOCARDIAL ISCHEMIA

This study tested a very small balloon catheter called Sapphire 3. Doctors used it to gently open long-term, completely blocked heart arteries before placing a stent. Researchers watched 170 patients to see if the device was safe and worked well during the procedure and for 24 ho…

This large study aimed to see if taking two blood-thinning medications (clopidogrel plus aspirin) is better than taking aspirin alone for patients with multi-vessel heart disease who have received a stent. It involved 8,250 patients across 100 centers and followed them for at lea…

This study looked back at 1,695 patients with stable multi-artery heart disease to see which treatment approach best prevents heart attacks and cardiac deaths specifically related to the treated arteries. Researchers compared outcomes for patients who had bypass surgery, stent pr…

This study tested whether a virtual cardiac rehabilitation program delivered via a mobile app could improve patients' health more than standard in-person rehab. It involved 259 adults who recently had a heart attack, stent placement, or heart surgery. Researchers compared how far…

This study checked if the Orsiro heart stent works as well in regular medical practice as it did in earlier research. It followed 556 people with clogged heart arteries who received the stent. Researchers tracked their health for 5 years to see how safe and effective the stent re…

This study tested new MRI scanning methods to get clearer pictures of bleeding inside the heart muscle after a heart attack. Researchers enrolled 14 patients who had recently had a heart attack to see if these new scans could better identify damage and predict who might develop f…

This study aimed to see how well a specific type of heart scan (stress CMR) predicts future heart problems like heart attacks or death in real-world patients. It followed 2,349 adults with chest pain or other signs of possible heart disease to track their health outcomes over tim…

This study investigated whether having heart surgery in the morning or afternoon affects how well heart muscle tolerates changes in blood flow. Researchers examined small heart tissue samples from 88 patients undergoing scheduled heart surgery. The goal was to understand if time …

This study aimed to find out if silent, painless episodes of reduced blood flow to the heart (silent ischemia) could predict future heart problems like heart attacks or death in people who already had coronary heart disease. Researchers followed 973 patients for one to three year…

This study aimed to measure how much radiation patients receive during common heart CT scans worldwide. Researchers collected data from 36 adults who needed these scans to check for heart disease. The goal was to understand current scanning practices and identify opportunities to…
