A team approach to coronary artery disease
Coronary artery disease (CAD)— when major arteries to the heart are damaged and blood flow is partially or totally blocked—is the most common type of heart disease in the U.S.
However, new technology, along with a team-based approach to treatment, have greatly improved patient outcomes, says interventional cardiologist Bruce Haik, MD, Chief of the Division of Cardiology and Director of the Cardiac Catheterization Lab at Cooperman Barnabas Medical Center (CBMC), who is also a member of RWJBarnabas Health Medical Group.
“Treating CAD sometimes involves a complex decision tree requiring a Heart Team consultation,” says Dr. Haik. “When a patient and family have input from cardiac specialists with a wide array of expertise, they can feel confident in making a decision about treatment.”
Members of the Team
CAD can be diagnosed in a variety of ways, including cardiac stress tests, which show how the heart works during physical activity; a coronary CT scan, a specialized, ultra-fast imaging test that can provide a calcium score and also provide noninvasive information about the arteries; and an angiogram, an X-ray that can accurately detect blockages. These tests are often ordered by a cardiologist, a doctor trained in finding, treating and preventing cardiac disease.
The noninvasive cardiologist may refer the patient to an interventional cardiologist. “This is a specialist in the nonsurgical opening of arteries,” says Dr. Haik. A procedure done by an interventional cardiologist is angioplasty, also known as percutaneous coronary intervention (PCI). In this procedure, a soft, flexible guide wire and various balloon catheters and devices are inserted into a narrowed blood vessel in order to open the artery with stents. The process is sometimes aided by imaging from within the blood vessel utilizing specialized imaging systems.
The interventional cardiologist will consult with a cardiac surgeon, whose specialty is open heart surgery, in which an incision is made in the chest in order to perform coronary artery bypass graft surgery, sometimes combined with valve repair or replacement.
Both of those doctors will rely on the information provided by a cardiac imaging specialist, who uses sophisticated technology to provide detailed images of a heart’s chambers, valves, walls and blood vessels. “It’s important to know the severity, location and extent of the narrowing, but also to understand whether the blockage is rigid and calcified, or is more consistent with soft plaque,” says Dr. Haik.
Making the Call
The Heart Team approaches each patient’s individual treatment plan by considering many clinical factors, including age, frailty and coexisting medical conditions like diabetes in order to achieve the best possible outcomes.
“The cardiology field has evolved so that we now have many effective ways of treating CAD and related conditions,” says Dr. Haik. “For example, the Shockwave balloon utilizes ultrasound waves to break up calcified plaque before placing a stent, allowing for more complete expansion.
“All of these options are weighed along with the particular patient’s risk profile,” he explains. “A major benefit of the Heart Team process is that sometimes a hybrid approach using both catheter-based procedures and surgery turns out to be the safest and most effective means of treatment."
