Diagnostic Testing for Heart Conditions

Diagnostic Testing

The human heart is a hard-working muscle that is vital for the proper functioning of the rest of the body. Without a healthy heart, your organs and tissues cannot receive adequate oxygen and nutrients, keeping them from performing at their optimal levels. There are many diagnostic procedures, both old and new, that physicians have at their disposal to check a patient’s cardiac condition. These diagnostic tests include, but are not limited to:

  • Contrast Echocardiography
    This test uses a contrast agent to visualize the structures of your heart with great clarity and detail. The contrast agent enhances the “echoes” that are reflected back from the heart to the transducer, which allows a physician to monitor various aspects of cardiac function.
  • Echocardiogram
    An echocardiogram is a test that uses the echoes of sound waves to produce a live image of the heart in motion. This test visualizes the shape and size of the heart and its chambers and valves.
  • Exercise Tolerance ECG
    This test monitors the functioning of your heart in response to increases and decreases in physical activity.
  • Holter Monitor
    When your physician cannot ‘catch’ a cardiac problem with a single ECG, he or she may order a Holter monitor test. This test is used to monitor the heart rhythm and rate continuously for a certain period of time.
  • Nuclear Imaging
    This test is performed to monitor the blood flow to the heart muscle through the coronary arteries. The scan uses a radioactive ‘tracer’ to visualize the blood flow to the heart muscle.
  • Vascular Ultrasound
    In this test, images of the vascular system are formed by ultrasound to evaluate the body’s arteries and veins.

Regional Medical Center of San Jose is proud to provide the full range of cardiac diagnostic tests to the community of San Jose, California. If you would like to learn more about our services, please contact our friendly staff at (408) 259-4000 today.

Identifying Your Risk Factors for Breast Cancer


Breast cancer occurs when cells in the breast tissue divide without control or order, free from the normal regulative processes of the body. After cells divide like this for a certain amount of time, a mass of tissue called a growth or a tumor forms. Cancerous tumors can invade nearby tissue and spread their cells to other organs and body structures. Although many may consider breast cancer as a disease that only affects women, it can actually occur more aggressively in men. Read on to learn about common breast cancer risk factors.

  • Sex
    Women are at a much higher risk of developing breast cancer, but men can also develop the disease
  • Age
    Men and women ages 50 and older are at a higher risk for breast cancer
  • Race
    Caucasians have shown to develop this type of cancer more often than any other race
  • Family history
    If any of your close relatives have battled this disease, you may be more likely to develop it
  • Personal history
    You are at higher risk if you have already had personal history with the disease
  • Changes in certain genes
    Changes in the BRCA1, BRCA2, and other genes put you at higher risk
  • Changes in breast tissue
    Changes can include atypical ductal hyperplasia, radial scar formation, and lobular carcinoma in situ (LCIS)
  • Radiation therapy before the age of thirty
  • Overuse of alcohol
  • Increased exposure to estrogen over a lifetime through:
    • Tobacco use
    • Early onset of menstruation
    • Late onset of menopause
    • No childbearing
    • Late childbearing
    • Absence of breast-feeding
    • Hormone replacement therapy
  • Increased breast density
    This occurs when the breast contains more ductal and lobular tissue and less fatty tissue

Brainstem Stroke: Causes, Symptoms, and Treatment Options

Brainstem Stroke

The brainstem is the nervous system tissue located beneath the cerebrum and directly above the spinal cord. It is partially responsible for controlling certain involuntary bodily functions, such as breathing, heartbeat, and blood pressure. The nerves used for eye movement, chewing, hearing, talking, and swallowing are also controlled by this part of the brain, making it essential to survival.

Similar to heart attack and stroke, a brainstem stroke occurs when blood flow to the tissue is obstructed or interrupted. If blood is unable to reach the tissue, the cells cannot be oxygenated and quickly die. If the brainstem cannot function properly due to dead or damaged tissue, involuntary bodily functions can no longer be regulated, resulting in death.

There are two main types of brainstem stroke: ischemic and hemorrhagic. The most common form is ischemic stroke, which is caused by the obstruction of a blood vessel that supplies oxygen to the brainstem. The hemorrhagic stroke is caused by a burst blood vessel, leading to bleeding and pressure in the brain.

To treat a brainstem stroke, the type of stroke must first be identified using diagnostic imaging technology. A CT scan or MRI may be used to image the brain and detect the cause of the stroke. Once the condition has been diagnosed, medications or surgery will be indicated to alleviate the symptoms and reduce damage to the tissue.

The symptoms of brainstem stroke are often sudden and severe and include the following:

  • Hearing loss
  • Problems with vital functions, such as breathing
  • Problems with sensation
  • Weakness or paralysis in the face, legs, and/or arms
  • Difficulty chewing, speaking, or swallowing
  • Vision problems
  • A feeling of spinning when not moving (vertigo)
  • Coma
  • ‘Locked-in syndrome’ (when only the eyes are able to be moved)

If you or another person experiences these symptoms, consider seeking emergency medical assistance immediately. Regional Medical Center of San Jose's Joint Commissioned Certified Primary Stroke Center is dedicated to providing patients with the emergency stroke care that they need.
