Pulmonary artery catheter use in cardiogenic shock patients
This trial studies whether using a special pressure-monitoring tube in the heart’s main artery (a pulmonary artery catheter) helps people who are in cardiogenic shock from weak heart pumping. If you qualify, the goal is to improve how doctors monitor and treat this dangerous, fast-moving condition.
Boston, MassachusettsAges 18–90 - NCT05655910Recruiting
Nutrition support program for people with LVADs in the hospital
This trial tests whether an enhanced nutrition plan can improve care for adults who already have an LVAD (a heart pumping device). It’s designed for hospitalized patients and looks at who can safely eat by mouth while avoiding high-risk situations.
New York, New YorkAges 18 years+ - NCT06070428Recruiting
A study on heart failure care after hospital discharge
This trial tests a new care approach for people with heart failure who are in the hospital or emergency room and planning to go home. The goal is to see if it helps them recover and stay healthy.
Detroit, MichiganAges 18 years+ - NCT06039176Recruiting
Learning from the HeartMate 3 device
This study looks at information from the HeartMate 3 LVAD device to learn more about how it works and what it can tell us about the future. It may help people with advanced heart failure who need this specific device.
San Francisco, CaliforniaAges 18–100 - NCT06053580RecruitingPhase 2
Valsartan for pulmonary hypertension: protection study
This trial tests whether a blood pressure medicine called valsartan can help protect the lungs and heart in people with a specific type of pulmonary hypertension (Group 1 PAH). If you have PAH and are stable enough to walk 50 meters, you may be able to join.
Seattle, WashingtonAges 18–80 - NCT06052475Recruiting
Pacemaker upgrade study for heart failure
This trial is for people with a standard pacemaker that stimulates the right ventricle most of the time. It tests whether a newer type of pacemaker (CRT) can improve heart function and symptoms. If you have a weakened heart (LVEF between 35-50%) and your heart failure has gotten worse, this study may be a good fit.
CambridgeAges 18 years+ - NCT05972356Recruiting
How heart relaxation affects outcomes in heart surgery
This study looks at whether a measurement of how well the heart relaxes helps predict outcomes after heart surgery. It focuses on patients treated in Amsterdam UMC and uses care data to understand who may be at higher or lower risk.
