Manager Aaron Boone to take immediate medical leave of absence

The New York Yankees today announced that Manager Aaron Boone is taking an immediate medical leave of absence to receive a pacemaker. Surgery is expected to be performed later today at St. Joseph’s Hospital in Tampa.

“As many of you know, I underwent open-heart surgery in 2009, and I wanted everyone to understand where I’m at regarding the procedure that’s taking place today,” said Boone. “Over the last six-to-eight weeks I’ve had mild symptoms of lightheadedness, low energy and shortness of breath. As a result, I underwent a series of tests and examinations in New York prior to the beginning of spring training, including multiple visits with a team of heart specialists. While the heart checkup came back normal, there were indications of a low heart rate which, after further consultations with doctors in Tampa, necessitates a pacemaker.

“My faith is strong, and my spirits are high. I’m in a great frame of mind because I know I’m in good hands with the doctors and medical staff here at St. Joseph’s Hospital. They are confident that today’s surgery will allow me to resume all of my usual professional and personal activities and afford me a positive long-term health prognosis without having to change anything about my way of life. I look forward to getting back to work in the next several days, but during my short-term absence, I have complete trust that our coaches, staff and players will continue their training and preparation at the same level as we’ve had and without any interruption.

“I also want to take this opportunity to remind all those dealing with heart issues to remain vigilant in your care and to reach out to your doctor should you have any symptoms of discomfort or trouble. Any issue involving the heart has the potential to be serious. Staying on top of your health is always the first and most important thing you can do for yourself and your family.”

“The thoughts of the entire organization are with Aaron and his family as he undergoes this procedure and takes the time he needs to properly heal,” said Yankees Managing General Partner Hal Steinbrenner. “Aaron leads our players, coaches and staff with a rare combination of work ethic, intelligence and a genuine concern for others. Our only priority at this time is Aaron’s health and well-being, and we will support him in every way throughout his recovery.”

General Manager Brian Cashman will be made available to New York-based media later today. A recording of his availability will be posted online for media not present.
