Veteran actor Saira Banu, admitted to the Intensive Care Unit of a hospital here, has been diagnosed with a heart problem and doctors are keen on an angiogram procedure but she has refused permission, a hospital doctor said on Thursday.

The 77-year-old "Padosan" actor, who lost her husband Dilip Kumar in July, was admitted to the Hinduja Hospital, a non-COVID-19 facility, in Khar on August 28 following breathlessness, high blood pressure and high sugar.
