To better understand the interactions between the ADRB1 (rs1801252 and rs1801253) and ADRB2 (rs1042713, rs1042714, and rs1800888) polymorphisms and cardiovascular events as well as all-cause mortality in CAD patients, we undertook a meta-analysis with the aim of obtaining information for individual CAD prognostication and potential clinical application. Here, ADRB2 is linked to coronary artery disorder.
