Remote ischemic preconditioning in elderly patients with acute myocardial infarction and transient ischemic attack: a retrospective cohort study
To evaluate the effects of remote ischemic preconditioning (RIPC) on major adverse cardiac and cerebrovascular events (MACCE) in elderly patients with acute myocardial infarction (AMI) and recent transient ischemic attack (TIA).
Key Findings:
Of 382 patients screened, 103 were analyzed (RIPC: 48; control: 55).
At 12 months, MACCE occurred in 29.2% of RIPC patients compared to 49.1% of controls (log-rank P = 0.033).
The adjusted hazard ratio for MACCE with RIPC was 0.725 (95% CI, 0.545–0.964; P = 0.026).
Higher baseline IL-6 and hs-CRP levels independently predicted MACCE.
Interpretation:
Adjunctive RIPC was associated with a lower risk of MACCE in elderly patients with AMI and TIA.
Limitations:
The study was retrospective and conducted at a single center, which may limit generalizability.
The sample size was relatively small, potentially affecting the statistical power.
Conclusion:
RIPC was associated with a lower 12-month risk of MACCE in elderly patients with AMI and TIA.
