Genome-wide Association Study of Development of Collateral Circulation for Patients With Coronary or Peripheral Artery Disease


The purpose of this study is to evaluate the genome-wide association for the development of collateral circulation for patients with coronary or peripheral artery disease and to develop the molecular genetic treatment model based on genome-wide association data.
