Mahmoud Abbas's private physician said Monday that the Palestinian leader is fit and dismissed concerns about his heart condition sparked by last week's medical procedures. Dr. Abdullah al-Bashir said he performed an angiogram on Abbas last Thursday to check for blocked blood vessels, a cause of heart attacks, but no problems were found. Abbas was promptly discharged afterward. The doctor said Monday the procedure was incorrectly reported as angioplasty at the time it was performed. An angiogram is an imaging test that uses x-rays to view blood vessels after a dye is injected into the body through a catheter. During angioplasty, doctors push a tiny balloon into an obstructed blood vessel, inflate it to flatten the clog, and often insert a stent to prop open the vessel.
