Heart Attack Warning Signs

Heart Health

A heart attack, also called myocardial infarction, is a life-threatening medical event. A heart attack occurs when blood flow to a part of the heart muscle is interrupted, resulting in damage or death of the muscle cells. Most heart attacks are caused by a blood clot blocking one of the coronary arteries, or the vessels that are responsible for delivering oxygen-rich blood to the heart. Once a vessel is blocked, the cells no longer receive the oxygen they need to function.

Heart attacks may also occur as a result of plaque buildup in the arteries. Plaque is a hard substance that is largely composed of cholesterol. When these plaques develop cracks or tears, blood platelets tend to stick to them and form a clot, which can also block blood flow to the heart.

Myocardial infarction can occur at any time, but is most common when a person is resting, is asleep, suddenly increases physical activity, suffers from a sudden, severe emotional or physical stress, or partakes in strenuous activity in cold weather. While some heart attacks set on suddenly and have intense symptoms, most start slowly with mild signs and progress in severity. Oftentimes, people are unsure of what is happening and wait too long to seek medical intervention. The signs of a heart attack include:

  • Severe or mild chest pain that lasts more than a few minutes or occurs intermittently; it can feel like bad indigestion, heavy pressure on the chest, or like a tight band is wound around the center of your chest
  • Shortness of breath, with or without chest pain
  • Nausea or vomiting
  • Pain or discomfort in the arms, back, neck, stomach, or jaw
  • Feelings of anxiety or impending doom
  • Dizziness or light-headedness
  • Fast or irregular heartbeat
  • Heavy sweating

If you experience possible heart attack symptoms, seriously consider calling 911 and seeking immediate emergency care. The Emergency Medicine and Trauma II Center at Los Robles Hospital & Medical Center provides cutting-edge emergency care for the community 24 hours a day, 7 days a week.

da Vinci Hysterectomy for Benign Conditions - Patient Education Video

Fibroid tumors, heavy bleeding, and pelvic pain are all benign conditions that may lead to a hysterectomy procedure. Traditionally, this procedure was performed as an open procedure, using a long, horizontal incision in the lower abdomen. Now, the da Vinci robotic surgical system can assist surgeons in performing a minimally invasive hysterectomy, resulting in less complications and a quicker recovery. In this video clip, you can learn more about this procedure and its benefits.

Los Robles Hospital & Medical Center of Thousand Oaks, California offers daVinci robot-assisted surgical procedures to our patients as an alternative to open surgery and conventional laparoscopy. Learn more about this exceptional technology by visiting our website or by contacting us at (805) 497-2727.

Qualities to Look for in a Hospital


When you are searching for health care for yourself or for a loved one, you want to be sure that the hospital you choose provides the highest quality care possible. To ensure you are being treated by a staff of dedicated, experienced healthcare professionals, look for the following qualities in your community hospital.

  • A wide variety of comprehensive services
    When choosing a hospital, be sure that it has a wide range of diagnostic, treatment, and rehabilitation services that may be necessary to take care of a variety of medical issues. Having an extensive amount of services available on-site is more convenient for both physician and patient and increases the efficiency of care.

  • Cutting-edge technology
    Recent advances in medicine and technology have allowed for the development of amazing new diagnostic imaging and treatment tools. The daVinci robotic surgery system, for example, provides a surgeon with increased precision, range of motion, and visualization while operating through tiny ‘keyhole’ incisions, eliminating the open incisions that were needed in the past. This minimally invasive surgical technique decreases a patient’s recovery time, risk for infection, and amount of pain and scarring. Be sure the hospital you choose provides their physicians with the most state-of-the-art diagnostic and treatment options to ensure you receive the best care possible.

  • Experienced physicians
    Be sure that your hospital is staffed with board-certified, experienced physicians that are dedicated to improving the overall health of their respective communities.

With over 500 board-certified physicians representing over 35 specialties, Los Robles Hospital & Medical Center offers a full range of medical services to provide each patient with the highest quality care possible. We are also the only Level II Trauma Center in Ventura County. Our committed staff is proud to be the community’s resource for quality health care.

A Look at Gamma Knife Technology


In many cases, it is extremely difficult or even impossible to remove brain tumors that are very deep-seated or located too closely to the sensitive areas of the brain’s vital tissue. When tumors such as these occur, the Gamma Knife can be the best possible treatment. Gamma Knife technology does not actually involve any knives or incisions at all—it is a medical device that utilizes precisely aimed beams of radiation to shrink or eliminate brain tumors. Since there is no incision needed, the brain is not exposed to the outside air, eliminating the complications that accompany traditional open surgery.

To find the precise target for the 201 beams of gamma radiation, a titanium imaging frame is fixed to the patient’s skull. Once the frame has been attached, an MRI or CT scan is utilized to image the patient’s brain, allowing the specialists to develop a personalized treatment plan. The beams of radiation are then specifically positioned so that they are directly focused on the area of the brain that is in need of treatment.

Gamma Knife technology can be used to treat the following disorders:

· Brain tumors (benign or malignant)

· Essential tremor and Parkinson’s disease

· Brain lesions

· Vascular malformations

· Movement disorders

· Trigeminal neuralgia

Gamma Knife precision minimizes radiation damage to the surrounding tissue. There is little or no discomfort associated with this procedure and the recovery time is brief. Without the need for incisions, the risk for bleeding and infection is generally eliminated.

Los Robles Hospital & Medical Center’s NeuroScience Gamma Knife Center is now in its fifth year of providing our community with the non-invasive treatment made available through the Gamma Knife technology and the expertise of our physicians.
