Haptoglobin phenotype as a predictor of restenosis after percutaneous transluminal coronary angioplasty

Am J Cardiol. 2001 Feb 1;87(3):330-2, A9. doi: 10.1016/s0002-9149(00)01368-0.


We have demonstrated that a genetic polymorphism in the antioxidant protein haptoglobin is important in determining which patients develop restenosis after percutaneous transluminal coronary angioplasty. Knowledge of the haptoglobin phenotype may be useful in the assessment and utilization of new therapies to reduce restenosis, particularly in patients who are homozygous for the haptoglobin 2 allele.
