Our Services

Cardiology

At St. Joseph Health Medical Group - Cardiology, we provide the most advanced, state-of-art care you expect and deserve. As a team, our doctors bring diverse knowledge and experience that includes board certification in cardiology and interventional cardiology. We also have a state-of-the-art Cardiology Clinic & Diagnostic Center - offering patients the best in heart care, backed by genuine and compassionate care for all your needs.

It is no secret that your heart is essential to everything in your life. Your ability to work or do what you love. Being there for your family and friends. Your life itself. That is why, when you're concerned about your heart or cardiovascular system, you need care that's uncompromising ... and unsurpassed.

We also know that a cardiovascular concern is personal, which is why our care is backed by genuine compassion for your individual needs. This means flexibility. It means taking the time that's needed to do things right. It means integrity and commitment. But most of all, it means we treat you, not just your heart.

State-of-the-Art Testing

State-of-the-Art Testing for the Most Appropriate Care

Understanding the nature and extent of your problem is the first step to making sure you’re getting the most appropriate, most effective treatment. So we use today’s state-of-the-art testing methods, such as:

  • Pacemaker Checks
  • Electrophysiology
  • Nuclear & Treadmill Stress Tests
  • Nuclear Cardiology
  • EKGs
  • Echocardiography - Ultrasound identifies problems of the heart valves and muscle function. Our digital system at St. Joseph Hospital provides higher-resolution images and faster diagnosis.
  • Stress testing, including nuclear - A noninvasive way to look for blocked arteries by stressing your heart with exercise or medications. Nuclear testing produces images of the heart’s structure and blood flow under stress.
  • Noninvasive vascular testing - We use ultrasound to check for blocked arteries in other parts of the body.
  • Heart monitoring - Portable monitoring to look for signs of irregular heart rhythms.
  • Catheterization & angiography - The “gold standard” in evaluating for blocked arteries. A small,flexible tube helps X-rays to “look for” blocked arteries and can help measure pressures in the heart and blood vessels.

Personalized Care From the Heart

A proactive, “interventional” approach to your health

To help ensure your best health, we take a more “proactive” approach than many cardiologists. This means we address problems early, especially things like cholesterol and high blood pressure that can lead to more serious concerns later on. We use the same approach for arrhythmia and heart failure management.

Sometimes the most appropriate thing we can do is to “intervene” for certain problems. With fellowship training and board certification in interventional procedures, we can perform various treatments (interventions) to repair blockages, remove clots and restore your blood flow. We know, however, that interventions are not always the right treatment. Our advanced training and skill mean we recommend and perform the procedures only when they are truly necessary.

Personalized care from the heart

We don’t just treat your heart. We treat you. We listen to you and spend the time to get to know you and understand your situation. We have genuine compassion, we care about the quality of your life, and you’ll always know that we’re doing all we can to accommodate your individual needs. In short, we’ll treat you the way we would want to be treated.

State-of-the-art treatments:

  • Angioplasty
  • CT angiography
  • Coronary angiogram
  • Coronary stenting
  • Internal cardiac defibrillators
  • Intravascualr ultrasound
  • Permanent pacemaker implantation
  • Critical care
  • Heart attack & heart disease prevention
  • Proactive care for obesity, high cholesterol & hypertension
  • Advanced heart failure & arrhythmia management
  • Lifestyle, nutrition & exercise counseling

Working with your doctor to meet your needs

We know you trust your doctor, and we support your healthcare. That’s why we maintain constant, detailed communication with your physician and are always available for consultation. We also help with insurance preauthorization and verification of benefits. But we think the reason so many doctors refer patients to us - including their own family members - is the quality of our care.

The Symptoms of Heart Disease

An ailment like high cholesterol can be considered a silent killer. You may not even recognize the symptoms upon being first diagnosed. The frightening reality is that some people don't even realize that they are suffering from heart disease until a heart attack happens. Pay attention to your body, and continually visit your doctor for thorough checkups.

  • Chest pain
  • Shortness of breath
  • Pain, weakness, or numbness in your limbs
  • Pain in your jaw, neck, stomach area, or back

Heart disease can also be caused by genetics or other defects. These might include irregular heartbeats, poorly functioning heart muscles (cardiomyopathy), infections to the heart, or valve complications. You might even require surgery to treat some of these conditions.

Preserving Your Health for the Future

If you don't already have one, we highly recommend that you consider taking up an ongoing heart health maintenance plan with your doctor right away to cut down on the possibility of your heart condition becoming more serious.

Take care of your heart with our help. Please visit us today so that we can answer any questions you might have about treating and preventing heart disease.

Patent Foramen Ovale Closure

A patent foramen ovale (PFO) is a hole in the heart that may lead to a stroke in some patients. A PFO is closed by using a double-disc device to seal over the hole, in a procedure that takes less than 1 hour. Dr. Andrew D. Michaels has performed over 200 of these procedures.

Coronary Artery Angiography

Coronary angiography uses x-ray technology to take pictures of the two heart arteries. This can show cholesterol buildup in the heart arteries, and guide treatment decision from medical therapy to stenting to bypass surgery. Dr. Michaels has performed over 8000 of these procedures.
