These patients are at a slightly higher risk of deep-vein thrombosis if they sit too long, Frid says. "So I also recommend that they don't sit in one spot for more than a few hours. Whether they're in a car or on a plane, they need to get up and walk around."
Maria Mileno, MD, director of the travel medicine service at the Miriam Hospital, Brown University School of Medicine, in Providence, R.I., also recommends that patients carry their medications on board with them. "It really helps if you have your own anti-angina drugs, since it's not standardized as to what drugs airlines ought to have on board an aircraft," Mileno says.
