Case history
Tam Mei-lan, 86, was out of breath and out of options when she consulted Dr Elaine Chau, a cardiologist at the Hong Kong Sanatorium and Hospital.
The health crisis began when sudden chest pain and severe breathlessness landed Tam (whose name has been changed to protect her privacy) in hospital. She had suffered a heart attack because not enough blood was reaching her heart.
