CORONARY DISEASE

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 compared two common treatments for people with multiple blocked heart arteries. Researchers tested whether using a special wire to guide stent placement (a less invasive procedure) works as well as traditional bypass surgery. The trial involved 1,500 patients and follo…

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 understand if differences in gut bacteria and bile acids are linked to coronary artery disease. Researchers compared 80 people undergoing a heart scan, dividing them into those with and without artery plaque. By analyzing stool and blood samples, they looked f…

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…
