Effect of Sodium Glucose Co-tansporter 2 Inhibitors (SGLT2I) on Inflammatory and Oxidative Stress Markers Level in Heart Failure Patients

This study is examining how a class of diabetes medications called SGLT2 inhibitors (commonly used for heart failure and diabetes) affect inflammation and oxidative stress (cell damage from unstable molecules) in patients with heart failure. Researchers hope this will explain why these drugs improve heart failure outcomes. **You may be eligible if...** - You are 18 or older with heart failure rated Class II–IV by standard criteria (moderate to severe symptoms) - You are already on standard heart failure medications (such as ACE inhibitors, beta-blockers, or diuretics) - You are starting or already taking an SGLT2 inhibitor as part of your regular care **You may NOT be eligible if...** - You have type 1 diabetes - You have severe kidney disease - You are pregnant or planning to become pregnant - You have had a recent heart attack or major heart procedure - You are allergic to SGLT2 inhibitor medications Talk to your doctor to see if this trial is right for you.
