Stroke treatment with tenecteplase via artery
This trial tests a clot-busting drug called tenecteplase given directly into the brain artery for people having a moderate stroke caused by a blockage in a medium-sized blood vessel. The goal is to see if it helps improve recovery when given within 24 hours of stroke symptoms starting.
Beijing, Beijing MunicipalityAges 18 years+ - NCT07357272Recruiting
Blood pressure benefits in sleep apnea patients after CPAP
This trial studies whether CPAP treatment can improve blood pressure in people with obstructive sleep apnea. It aims to find out who benefits most from CPAP in terms of blood pressure control.
Beijing, Beijing MunicipalityAges 18–70 - NCT07352709Recruiting
Ventilation feedback simulation for EMS crews
This trial tests a simulation tool that gives feedback on ventilation performance. It is designed for currently active EMS professionals to see if the tool improves their skills.
Dallas, TexasAges 18–60 - NCT07353892Recruiting
Robotic exoskeleton therapy for heart or lung surgery recovery
This trial tests whether using a robotic exoskeleton during physical therapy helps people recover more quickly after heart or lung surgery. The device supports your body as you practice standing and walking, even if you need a lot of help from your therapist.
Dallas, TexasAges 18 years+ - NCT07353775Recruiting
Heart procedure using imaging and pulsed energy
This trial uses a special imaging tool inside the heart to guide a new type of energy (pulsed field) to treat a specific area in the heart that can cause atrial fibrillation (an irregular heartbeat). It may help people with paroxysmal or persistent atrial fibrillation who need a procedure called CTI ablation.
BeijingAges 18 years+ - NCT07354568Recruiting
Mixed heart and blood vessel shock study
This study looks at people with a severe type of shock that affects both the heart and blood vessels, treated in the intensive care unit. It aims to understand how these patients recover and what factors impact their survival.
Amiens, SommeAges 18 years+ - NCT07360067Recruiting
Comparing two types of heart pacing for sick sinus syndrome
This study compares two different ways of placing a pacemaker lead to see which one better helps heart function and reduces future heart problems in people with sick sinus syndrome.
Seoul, SeoulAges 19 years+ - NCT07353424Recruiting
Salicornia extract for memory after a small stroke
This study tests whether a polyphenol-rich extract from a salt-tolerant plant called Salicornia can slow memory decline in people who have had a lacunar stroke. It compares the extract to the usual care you would receive.
SevilleAges 40–90 - NCT07354399Recruiting
Strength and cardio training for women with heart disease
