Outcome Measures

Primary Outcomes (1)

  • the neurological injury markers, including serum level of S-100B and NSE

    the biomarkers of brain injury

    before surgery, 6h, 24h, 48h, and 72h after bypass

Secondary Outcomes (1)

  • mini-mental state examination scale

    6 months after surgery

Study Arms (2)

sham RIPC

SHAM COMPARATOR

Patients had a deflated cuff placed on the right upper arm for 30 min.

Procedure: sham RIPC

RIPC treatment

EXPERIMENTAL

RIPC consisted of three 5-min cycles of right upper arm ischemia, which was induced by an automated cuff-inflator placed on the right upper arm and inflated to 200 mmHg, with an intervening 5 min of reperfusion during which the cuff was deflated

Procedure: RIPC

Interventions

RIPCPROCEDURE

RIPC consisted of three 5-min cycles of right upper arm ischemia, which was induced by an automated cuff-inflator placed on the right upper arm and inflated to 200 mmHg, with an intervening 5 min of reperfusion during which the cuff was deflated

Also known as: remote ischemic preconditioning
RIPC treatment
sham RIPCPROCEDURE

Patients had a deflated cuff placed on the right upper arm for 30 min without any inflation procedure.

Eligibility Criteria

Age18 Years - 70 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients diagnosed with acquired heart valve diseases scheduled for valve replacement or CABG

You may not qualify if:

  • Were unable to give informed consent
  • Patients who presented with other systemic diseases such as hepatic,renal, and pulmonary diseases, or have had a heart operation before, were excluded.
  • Additionally, patients taking antidiabetic sulfonylurea or glibenclamide were excluded because these agents have been shown to abrogate the cardioprotection elicited by ischemic preconditioning.
