This phase 2 trial tests whether a combined antioxidant therapy—ascorbate, N-acetylcysteine, and deferoxamine—can reduce heart muscle damage when given before and during angioplasty for a first anterior ST-elevation heart attack. Adults eligible for primary PCI will be randomly a…

This study tests NeoMayor, a smartphone app that gives personalized advice on exercise, diet, sleep, and mood to improve heart health. Researchers will enroll 240 adults aged 55 to 75 in Chile who are at risk for heart problems. Participants use the app for 4 months, and some als…

This pilot trial tests whether a structured respiratory self-care program, called AIRE, can help adults aged 60 to 80 recover from acute respiratory infections without complications. Participants receive a short education session on hydration, safe activity, warning signs, and si…

This study follows 75 older adults having elective heart surgery to understand why some recover quickly while others face complications like delirium or slow recovery. Researchers will measure frailty, physical and mental function, and a blood marker of biological stress called G…
