Hypothesis
Can angiogenesis-related proteins serve as biomarkers to predict major adverse cardiovascular events in patients with peripheral artery disease?
Conclusion
Endostatin, ANGPTL4, and ANGPTL3 are independently associated with major adverse cardiovascular events in patients with peripheral artery disease.
Supporting Evidence
- Endostatin levels were significantly higher in PAD patients with major adverse cardiovascular events.
- ANGPTL4 and ANGPTL3 also showed significant elevation in PAD patients with adverse events.
- These proteins were independently associated with cardiovascular events after adjusting for other risk factors.
Takeaway
Doctors can measure certain proteins in the blood to see if patients with leg artery problems are at risk for serious heart issues.
Methodology
A prognostic study measuring plasma concentrations of 22 angiogenesis-related proteins in a cohort of 406 patients over 2 years.
Potential Biases
Potential bias due to single-center study design and lack of drug treatment data.
Limitations
The study was conducted at a single center, and longer follow-up is needed to fully understand the prognostic value of the proteins.
Participant Demographics
Mean age 68.8 years, 33% female, with 254 patients having peripheral artery disease.
