Brief Summary

Remote ischaemic conditioning (RIC) is known to reduce infarct size post MI when used in the peri/immediate post infarct period. However little is known as to the effect of repeated remote conditioning post-MI (Myocardial Infarction) on not only infarct size, but also on ventricular remodeling and ultimately cardiac failure. In this phase II first in man trial, the investigators intend to carry out daily remote ischaemic conditioning in post MI patients. The principal hypothesis is that RIC applied on a daily basis for 4 weeks following a heart attack improves the ejection fraction at 4 months as assessed by cardiac magnetic resonance imaging.

Outcome Measures

Primary Outcomes (1)

  • Mean change in LVEF from baseline to 4 months as assessed by cMRI

    Mean change in LVEF from baseline to 4 months as assessed by cMRI

    Participants will be followed for a total of 4 months from date of MI to final outpatient follow-up at which point they will be discharged. Primary outcome measure assessed at baseline and 4 months post MI.

Secondary Outcomes (3)

  • Final infarct size at 4 months as assessed by cMRI

    Participants will be followed for a total of 4 months from date of MI to final outpatient follow-up at which point they will be discharged. Secondary outcome measure assessed at 4 months post MI.

  • Mean blood biomarker levels of heart failure and ventricular remodelling at baseline and 4 months

    Participants will be followed for a total of 4 months from date of MI to final outpatient follow-up at which point they will be discharged. Secondary outcome measure assessed at baseline and 4 months post MI.

  • Mean KCCQ score at 4 months

    Participants will be followed for a total of 4 months from date of MI to final outpatient follow-up at which point they will be discharged. Secondary outcome measure assessed at 4 months post MI.

Study Arms (2)

Treatment arm

EXPERIMENTAL

Participants in this arm will receive remote ischaemic conditioning on a daily basis for 4 weeks post MI

Procedure: Remote Ischaemic Conditioning administered via the inflation of a blood pressure cuff on the upper arm

Sham arm

SHAM COMPARATOR

Participants in this arm will receive sham ischaemic conditioning on a daily basis for 4 weeks post MI

Procedure: Sham conditioning

Interventions

Suprasystolic blood pressure cuff inflation for set periods to time to render a limb ischaemic followed by periods of deflation to allow for reperfusion.

Also known as: The electronic blood pressure cuff used to induce conditioning is the Accoson Greenlight 300., Cell Aegis AutoRIC machine
Treatment arm

Non therapeutic inflation of a blood pressure cuff that does not cause ischaemia/reperfusion injury

Sham arm
