CORONARY DISEASE

This study tested two ways to pace the left side of the heart in people with severe heart failure. The standard method uses veins on the heart's surface, while the new method paces from inside the heart chamber. Researchers wanted to see if the inside approach offers more pacing …

This study looked at whether taking two blood thinners (clopidogrel and aspirin) for a longer time after getting a heart stent helps prevent future heart attacks, strokes, or death in people with multiple blocked heart arteries. About 8,250 adults aged 18-75 who already had a ste…

This study compared two ways to treat people with severe blockages in multiple heart arteries: a less invasive procedure using stents guided by a pressure wire (FFR-guided PCI) versus open-heart bypass surgery (CABG). About 1,500 adults with chest pain or signs of heart strain to…

This study tested a tiny balloon catheter designed to open completely blocked heart arteries (chronic total occlusions) before placing a stent. 170 adults with coronary artery disease took part. The main goal was to see if the balloon could be safely delivered, inflated, and remo…

This study looked at whether silent myocardial ischemia (reduced blood flow to the heart without symptoms) increases the risk of heart-related death or problems in people with coronary heart disease. Researchers followed participants for one to three years to track outcomes. The …

This study looked at the gut bacteria and bile acids of 80 people—some with coronary artery disease and some healthy. Researchers wanted to see if differences in gut microbes and bile acids might be linked to heart disease. The study was purely observational, meaning no treatment…

This study measured the amount of radiation people receive during a common heart scan called CCTA. Researchers collected data from 66 adults at multiple hospitals worldwide to see how radiation doses vary and how often dose-saving techniques are used. The goal was to help make th…
