Doctors say Bernie Sanders is fit for the presidency nearly three months after heart attack

Sen. Bernie Sanders, I-Vt., on Monday released the results of his most recent annual physical exam, as well as letters from three of his doctors, making him the second septuagenarian in the Democratic presidential contest to offer an inside look at the details of his health.

"You are in good health currently, and you have been engaging vigorously in the rigors of your campaign, travel and other scheduled activities without any limitation," Dr. Brian Monahan, the attending physician for members of Congress, wrote.

Sanders' latest physical exam was conducted on Dec. 19, according to Monahan. The results of the exam revealed that the senator's blood pressure, heart rate and blood tests were "normal." Sanders is 6-feet tall and weighs 174 pounds, Monahan wrote in the letter, which is similar to what most recent presidential candidates have released.
