Heart Attacks & Cardiovascular Care

Whether its from high blood pressure, cholesterol, genetics, or more complicated causes, cardiovascular issues like coronary artery disease can’t always be managed by medications alone.  If you are considering surgery for your cardiovascular disease, our team will place you in the best hands available.

2023-24 US News Cardiology Badge

Our surgeons are world leaders in coronary artery bypass grafting (or CABG—pronounced like “cabbage”), the procedure that redirects blocked arteries to get blood flowing to your heart again.  We perform these procedures more often than most other hospitals in the country, and all that experience allows us to deliver results that are among the best in the country.

We’re here to help you make the most informed decision when it comes to treating your cardiovascular disease and preventing future heart attacks.  Working closely with your primary doctor, cardiologists and cardiac imaging experts, we’ll let you know your surgical options and what to expect before, during and after your procedure.

We pride ourselves on developing personalized care plans for each and every person we treat, including for those with highly complex cases that other programs aren’t equipped for.
