Remote Ischaemic Conditioning in STEMI Patients in AFRICA: The RIC-AFRICA Trial
The RIC-AFRICA trial is a multi-centre, sham-controlled, randomised controlled trial (RCT) involving 1400 ST-segment elevation myocardial infarction (STEMI) patients presenting within ≤ 24 hours of myocardial infarction (MI) onset, across approximately 25 sites in 7 African countries (South Africa, Kenya, Sudan, Uganda, Mozambique, Senegal and Mauritius). Patients presenting with STEMI and deemed ineligible for the RIC AFRICA RCT because they present \>24 hours from MI onset but less than 72 hours, will be recruited into the observational arm of the study with the same endpoints as the trial. The purpose of the RCT is to determine whether Remote Ischaemic Conditioning (RIC) can reduce the rates of all-cause death and early post-myocardial heart failure at 30-days in STEMI patients treated predominantly with thrombolytic therapy.
⁃ I. Adult patients (≥18 years old) presenting with suspected STEMI (ST-elevation at the J-point in two contiguous leads ( ≥ 0.2mV in men or ≥ 0.15mV in women in leads V2-V3 and/or ≥ 0.1mV in other lead); and II. Within 24 hours of onset of myocardial infarction as deemed by the attending clinician; and III. Signed informed consent.
⁃ I. Signed informed consent; and
⁃ II. Clinical evidence of STEMI older than 24 hours and less than 72 hours as defined by:
• Compatible history with maximal chest pain between 24 -72 hours prior to presentation; and
• Compatible biomarkers (elevated cardiac troponin); and
• ECG compatible with recent STEMI; and/or
• Compatible echocardiography.
