Arm cuff therapy may shield heart and brain after stroke
NCT ID NCT07531394
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a simple, non-invasive treatment called remote ischemic conditioning (RIC) for people who have had a stroke and also developed heart muscle injury. RIC involves using a blood pressure cuff on the arm to briefly restrict blood flow, which may trigger the body's own protective responses. The trial will include 580 adults and compare RIC to a sham procedure given twice daily for 14 days, with a 3-month follow-up to see if it reduces major heart and brain complications.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Age ≥ 18 years, regardless of sex; 2. AIS confirmed by neuroimaging within 72 hours of symptom onset (or last known well time); 3. Acute myocardial injury confirmed by serial measurements of plasma cardiac troponin (cTn) within 72 hours of symptom onset \[19\]; 4. Written informed consent provided by the participant or their legal authorized representative. Exclusion Criteria: 1. Pre-stroke mRS score ≥ 2; 2. AIS patients receiving intravenous thrombolysis or endovascular thrombectomy; 3. Definite history of coronary heart disease, severe valvular heart disease, arrhythmia, heart failure, cardiomyopathy, elevated cTn, and abnormal electrocardiogram (ECG) before onset; 4. Suspicious cardiac-related symptoms (recurrent/persistent chest pain/chest tightness/palpitations, etc.) within 14 days before the index stroke; 5. Any disorder that could potentially lead to elevated pre-stroke cTn: sepsis, acute kidney injury, rhabdomyolysis, major cardiac surgery or myocardial infarction, previous ischemic or hemorrhagic stroke, congestive heart failure, pulmonary embolism, deep vein thrombosis, endocarditis, severe anemia, thyroid dysfunction, Drug application, etc.; 6. Patients who are planning for percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) for the index AMI within 3 months; 7. Severe liver or kidney dysfunction or malignant tumors; 8. Uncontrolled hypertension (systolic blood pressure ≥ 200mmHg at enrollment despite medication); 9. Any limb deformity, vascular or soft tissue injury, orthopedic trauma, or other conditions affecting the implementation of RIC; 10. Pregnancy or lactation period; 11. Patients with psychiatric disorders or other reasons unable to cooperate with treatment and follow-up.
