Heart bypass surgery (CABG) mortality

A heart bypass surgery, also known as coronary artery bypass graft (CABG) surgery, is a surgery in which the blood flow is rerouted through a new artery or vein that is grafted around diseased sections of a patient’s coronary arteries to increase blood flow to the heart muscle tissue.

Performing a CABG surgery requires proficiency, which may help to prevent serious complications, such as heart attack, stroke and death. While some patients have higher risks than others, some of these complications may be preventable. A lower death rate may indicate that a hospital provides a higher level of care.

About this measure

Mortality is the statistical measure of the percentage of people who die. This measure tracks the percentage of patients who had a CABG surgery; either an isolated CABG or a CABG in conjunction with any other cardiac surgeries, and died.  The second graph shows a trend over time for this measure.

Note: In this case, a lower number is better.
