General Cardiology at Dignity Health Arizona

Many patients are referred to a cardiologist by their primary care doctor. The primary care doctor may identify something in their patient’s heart rhythm that makes them worried. As a result, they transfer their patient to a cardiologist can closely examine the patient’s heart, determine what the problem is and work with the general practitioner to create a treatment plan designed to provide the best results for the patient.

Chandler Regional and Mercy Gilbert Medical Centers offers a full range of cardiac diagnostic services to identify and treat heart disease for the communities we serve in Arizona’s East Valley.

Noninvasive Cardiac Diagnostic Services

Our tests include:

  • Electrocardiogram(EKG)—checks for problems with the electrical activity of your heart
  • Echocardiogram—a type of ultrasound that evaluates how your heart muscle and valves are working
  • Cardiac stress tests—monitors how your heart functions while exercising or under exertion
  • Nuclear medication scan—identifies damaged heart muscle and how blood is flowing to and from your heart

Invasive Cardiac Diagnostic Services

Chandler specialists perform heart catheterization to identify problems with the coronary arteries and the valves of the heart. In this test, we evaluate blood flow in the coronary arteries using X-ray equipment, specialized catheters and contrast dye. We check blood flow and pressure in the heart chambers to see how well the heart valves work.

Often the first indication of an artery blockage is a heart attack. During a heart attack, oxygen rich blood cannot flow to the heart, causing heart tissue to deteriorate and die. Fast diagnosis and treatment is critical during this time.

Based on the test results, your doctor will either proceed with intervention or prescribe medication to treat the coronary artery disease. Intervention could include angioplasty, where a small balloon is placed and inflated to reopen narrowed arteries. The American College of Cardiology and American Heart Association recommends a less than 90 minute door-to-balloon time. Over the past year, Chandler Regional’s average door-to-balloon time has been less than 60 minutes.

Angioplasty may be followed by the implantation of a stent, a small metal mesh tube used to keep the artery walls open.

Catheterization (Cath) Lab Procedures

In addition to heart catheterization, we perform other cardiac diagnostic services in the new Chandler Regional Cath Lab, including intravascular ultrasound. In this test, sound waves are used to see inside the blood vessels. If a blood clot is found, our specialists will perform a thrombectomy to remove it.

Peripheral vascular disease, a blockage in the large arteries (not within the coronary arteries) can also be diagnosed in the Cath Lab. Our specialists place a stent in the blocked peripheral artery and perform a thrombectomy to remove the clot.

About 750,000 people in the U.S. have heart attacks each year. Of those about 116,000 die.
Many of these patients experience early symptoms.

The goal of heart disease treatments may include:

  • Lower the risk of blood clots from forming which can lead to heart attack
  • Prevent further complications from coronary heart disease
  • Reduce risk factors that contribute to the build-up of plaque in arteries
  • Relieve other symptoms such as shortness of breath and fatigue

Heart disease treatments may include:

  • Medical therapy
  • Medications specific for heart disease
  • Weight reduction
  • Smoking cessation
  • Exercise program
  • Intervention
  • Diagnostic angiograms
  • Coronary balloon and stent procedures to open plaque-clogged arteries
  • Surgical repair, open heart surgery or bypass surgery to increase blood flow to the heart
  • Maintenance

Schedule routine diagnostic testing to monitor your heart disease.

Heart disease treatments vary based on the severity of your disease. Someone who is high risk for developing coronary heart disease will have a different treatment plan than someone who has already suffered a heart attack.

Active participation in your treatment is essential to your health and wellness. The staff of the heart services department encourages you to be an active participant in your heart disease treatment. Please ask questions about anything you do not fully understand.
