Sauna therapy for heart failure symptoms
Part of Heart & circulation clinical trials.
This study tests whether regular sauna sessions can help reduce fluid buildup and the need for water pills (diuretics) in people with heart failure and reduced heart pumping function. If you are starting a hospital rehab program, this might help you feel better and use less medication.
Summary written for real people, not researchers, by Clin2.

- You take at least 40 mg of furosemide (or an equivalent water pill) daily for at least 30 days.
- Your NT-proBNP is over 400 pg/ml or your BNP is over 100 pg/ml.
- Your resting blood pressure is 100 mmHg or higher.
- Your kidney function (eGFR) is 20 ml/min/1.73 m² or higher.

This study looks at how your kidneys handle salt and water when you're treated for acute heart failure in the hospital. Researchers want to understand which patients recover well from fluid buildup and which might need different treatment approaches.
This study tests whether using a low-sodium salt substitute can help people with heart failure live longer, avoid hospital visits, and feel better. It's for adults with a weakened heart pump who have a caregiver and eat home-cooked meals.
This study tests whether measuring sodium levels in your urine can help doctors adjust your diuretic (water-removal) medications more effectively during heart failure hospitalization. The goal is to reduce fluid buildup and improve your symptoms.
This trial tests whether high-intensity resistance training in water can improve strength and function in people with chronic heart failure. It's designed for those who are stable on medication and not yet in a rehab program.
This trial tests if adding acetazolamide (a water pill) to your usual heart failure treatment can help you lose extra fluid and relieve symptoms. It is for patients recently hospitalized or seen urgently for heart failure worsening.
This study tests a special exercise program for people with advanced heart failure (NYHA class III or IV) who are afraid to move. The goal is to help you feel better and be more active.
