Deaths following heart bypass surgery (CABG)

A heart bypass surgery, also known as coronary artery bypass graft (CABG) surgery, is a surgery in which the blood flow is rerouted through an artery or vein that is grafted around the diseased sections of a patient’s coronary arteries.  This surgery is done to improve blood flow to the heart muscle. It is considered an isolated CABG when it is not performed in conjunction with any other surgeries.

CABG requires proficiency with the use of complex equipment; and technical errors may lead to serious complications, such as heart attack, stroke, and death.

About this measure

Mortality is the statistical measure of the percentage of people who die. This measure tracks the percentage of patients from 2012 who had an isolated CABG surgery and died during the hospitalization or after discharge from the hospital but within 30 days of the surgery.  

Note: This measure represents those patients that required the use of a heart-lung machine during their surgery.  A heart-lung machine is a device used in open heart surgery to support the body during the surgical procedure while the heart is stopped.

In this case, a lower number is better.
