Study of AP31969 for atrial fibrillation rhythm control
This study tests a new medication, AP31969, to control heart rhythm in people with atrial fibrillation. It compares the drug to a placebo to see if it can reduce how often AF episodes happen over time.
Plovdiv, PDAges 18 years+ - NCT07268846Recruiting
Prebiotic supplement before colorectal cancer surgery
This trial tests if taking a postbiotic supplement before surgery for colorectal cancer can improve recovery. It may help patients with adenocarcinoma of the large intestine prepare for their operation.
São Paulo, São PauloAges 18 years+ - NCT07268859Recruiting
Fan to prevent ticagrelor-related shortness of breath
This study tests whether using a small fan can help reduce the shortness of breath (dyspnea) that some people feel when they first start taking the blood thinner ticagrelor after a heart attack.
Istanbul, AvcılarAges 18–65 - NCT07269366Recruiting
Surgery vs stents for heart disease with weak heart pump
This trial compares two ways to restore blood flow to the heart—bypass surgery (CABG) or stents (PCI)—in people whose heart pumps weakly (LVEF 40% or less). It aims to find which method works better for chest pain or recent heart issues.
GroningenAges 18 years+ - NCT07270172Recruiting
Micronutrient study for type 1 diabetes complications
This study tests how a specific drug affects heart and kidney health in people with type 1 diabetes who already have some complications like kidney disease, heart problems, or obesity. It aims to find new ways to prevent further damage.
