The Journey of Capital Hospital started in 1969 as a small day care Medical Centre to provide preventive and curative medical facilities on outpatient basis to the employees of the Capital Development Authority in particular and residents of Islamabad in general.

A Mobile Coronary Care Unit was introduced by the hospital in November 1982, as an extension of the hospital based coronary care unit.
