Coronary Artery Bypass Graft Volume

Coronary Artery Bypass Graft (CABG) is a surgical procedure performed as a treatment for blocked or narrowed arteries in the heart. The purpose is to increase circulation and oxygen delivery by creating new routes for blood to travel around (or "bypass") the narrowed and blocked arteries.

The following are the number of isolated Coronary Artery Bypass Graft (CABG) surgeries performed at John Muir Health's Concord and Walnut Creek Campuses during the calendar years 2005 and 2006. "Isolated" refers to the fact that no other procedure was performed in combination with the CABG, such as valve repair or replacement.

Coronary Artery Bypass Graft Mortality

The following are the actual and expected mortality rates associated with isolated Coronary Artery Bypass Graft (CABG) surgeries performed at John Muir Health's Concord and Walnut Creek campuses during calendar years 2005 and 2006. The "expected mortality" is the number of predicted deaths after adjusting for the risk factors of John Muir's patient population.

Cardiac Catheterization Procedures

The following are the number of cardiac catheterization procedures performed at John Muir Health's Concord and Walnut Creek Campuses during the calendar years 2005 and 2006. Diagnostic cardiac catheterization is a procedure that evaluates the coronary arteries for blockages and determines how well the heart is pumping. If blocked arteries are found during a diagnostic cardiac catheterization, a percutaneous coronary intervention (PCI) may be performed to open the blocked artery.

Acute Myocardial Infarction (Heart Attack)

The goal of the John Muir Health Chest Pain Centers is to have a heart attack victim in the cardiac catheterization laboratory and open a blocked coronary artery within 90 minutes or less from the time the patient enters the hospital's emergency department. The "door-to-balloon" time is measured as the time the patient enters the emergency department ("door") to the time the blocked artery is opened by a balloon catheter ("balloon").

2007 John Muir Health "Door-to-Balloon" Times (Concord and Walnut Creek campuses combined):

75 minutes

Blue Shield Center of Excellence

John Muir Medical Center, Concord Campus has met the criteria for participation in the 2007 Blue Shield of California Cardiac Quality Initiative. John Muir's Concord Campus is one of 20 California hospitals, and one of six Bay Area hospitals, that met the cardiac quality criteria set by Blue Shield. To be considered for this designation, hospitals must perform a minimum of 150 cardiac surgeries and 300 percutaneous coronary interventions (PCI) per year. Inclusion in Blue Shield's program is based upon:

Coronary bypass surgery mortality
PCI mortality
Use of the internal mammary artery during coronary bypass surgery
"Door-to-balloon" times
Participation in the Society of Thoracic Surgeons and American College of Cardiology databases.
