When necessary, angioplasty and stent procedures can also be performed in the Cath Lab, providing you with minimally invasive treatment options for various heart conditions.

Electrophysiology lab

Our Electrophysiology Lab offers advanced technology for detecting abnormal heart rhythms (arrhythmias), such as atrial fibrillation (AFib). If an arrhythmia is detected, our electrophysiologists can locate exactly where it occurs in your heart. This helps us determine the most effective treatment for you.

Heart attack treatment

If you think you or a loved one are experiencing a heart attack, our skilled physicians are ready to provide immediate care in our emergency room (ER).

Heart attack symptoms

It's important to recognize the signs and symptoms of a heart attack, as every second is critical to your own or a loved one's well-being. Some of the more common signs of a heart attack include:

  • Cold sweats
  • Chest discomfort, including pressure, squeezing, fullness or pain that lasts for more than a few minutes or that subsides and then returns
  • Discomfort in the upper body, including pain in one or both arms or the back, neck, jaw or stomach
  • Indigestion or gastric fullness that is not relieved by antacids
  • Nausea
  • Shortness of breath
  • Sudden lightheadedness
Heart attack risk factors

In men, the risk of a heart attack increases at age 45. In women, heart attacks are more likely to occur if you have experienced menopause or are 50 years old or older.

Additional factors that may put you at a higher risk of having a heart attack include:

  • Tobacco use
  • Obesity
  • Family history of premature coronary artery disease
  • Diabetes
  • High cholesterol
  • Hypertension
  • Peripheral artery disease
  • Symptomatic carotid arterial disease

If you want to reduce your chances of heart damage, we encourage you to talk to your doctor about how you can make the following lifestyle modifications:

  • Eat a diet that is low in saturated fat and high in fiber
  • Exercise regularly
  • Lose weight if you are overweight or obese
  • Quit smoking

Stroke treatment

A stroke is a medical emergency during which blood flow to the brain is either reduced or stopped, depriving brain tissue of essential oxygen and nutrients. A stroke may cause loss in brain function and affect movement and speech.

Our ER offers 24/7 stroke treatment. Timely treatment decreases the likelihood of developing a stroke-related disability.
