Pulmonary Artery Catheter in Cardiogenic Shock Trial

This study is testing whether using a pulmonary artery catheter — a thin tube inserted into the heart's right side to precisely measure pressure and blood flow — improves outcomes for people in cardiogenic shock (a life-threatening condition where the heart suddenly can't pump enough blood to meet the body's needs). **You may be eligible if...** - You are between 18 and 90 years old - You have acute (sudden) heart failure with cardiogenic shock and your heart's pumping function (ejection fraction) is 40% or lower - You have dangerously elevated blood lactate levels and at least two signs of shock (very low blood pressure, need for medications to support blood pressure, or signs of fluid buildup) - Your shock started within 24 hours before screening - You or your legally authorized representative can provide consent **You may NOT be eligible if...** - Your heart failure and shock does not meet the specific criteria above - Your ejection fraction is above 40% - Your shock has been ongoing for more than 24 hours before screening Talk to your doctor to see if this trial is right for you.
