This study looks at whether taking blood thinners for just 1 month after getting a heart stent is as safe and effective as the usual 12 months. It involves over 3,700 people with acute coronary syndrome. Doctors also compare using ultrasound guidance during stent placement versus…

This study tests if using a drug-coated balloon (DCB) instead of a regular balloon for the side branch after main artery stenting can reduce major heart problems like heart attack or death within one year. About 784 adults with coronary artery disease and complex blockages at bra…
