What is heart failure ? and name some examples?
Is a result of inadequate pumping of blood around the body
- Myocardial infraction

- Valvular disease
What does partial blockage in a coronary artery cause ? and why ?
- Angina
- Reduced blood flow causes myocardial ischaemia
What is renal failure? and how is it related to myocardial ischaemia
