Is this trial a fit for you?

Likely a good fit

Ideal candidates are patients aged 45 years or older scheduled for non-cardiac surgery.

Probably not a fit

Patients with recent myocardial injury or those expected to have less than two days of hospitalization may not benefit from this study.

What this trial studies

This observational study investigates the relationship between endothelial dysfunction and cardiovascular events in patients scheduled for non-cardiac surgery. Researchers will evaluate flow-mediated dilatation of the brachial artery and measure troponin levels before, during, and after surgery. A total of 200 patients aged 45 and older will be enrolled, and their clinical outcomes will be monitored at one, three, and six months post-surgery. The study aims to enhance understanding of how endothelial function impacts surgical outcomes and cardiovascular health.

Why it matters

Potential benefit: If successful, this study could lead to improved risk assessment and management strategies for patients undergoing non-cardiac surgery.

How similar studies have gone: Previous studies have indicated a correlation between endothelial function and cardiovascular events, suggesting that this approach may yield valuable insights.
