Case Study: Mr Tupa Savea is a 54 year old male who has been transferred to the coronary care unit (CCU) from the emergency department for management of episodic chest pain. He has a history of stable angina and mitral valve stenosis. Mr Savea is of Samoan background and has lived in regional Queensland for the last 20 years with his wife and children. He was brought in by ambulance having had chest pain and shortness of breath. He reports having similar symptoms on and off for the past two months but did not visit his GP as he assumed the discomfort was due to indigestion. Mr Savea is an ex-smoker, tobacco free for the last six months and a social drinker (approx. 10 units/week). He works full-time as an orderly at a local hospital and is active in the Samoan support community. On assessment Mr Savea’s vital signs are: PR 90 bpm and irregular; RR 12 bpm; BP 150/100mmHg; Temp 36.9°C; SpO2 98% on oxygen 8L/min via Hudson mask. He has a body mass index (BMI) of 35 kg/m2 indicating clinical obesity. Blood test results show elevated cardiac enzymes and troponin levels and cholesterol level of 8.9mmol/L.
