Frequently Asked Questions

Is a heart attack the same as a cardiac arrest?

No, they are not the same.  The easiest way to describe the difference is that a heart attack is a plumbing problem and cardiac arrest is an electrical problem.  Both are severe, but a heart attack is where the coronary arteries are blocked and caused death of cardiac muscle, a cardiac arrest is where the conduction cycle of the heart is interrupted or stops functioning, resulting in the heart stopping beating.

Why am I on statins if my cholesterol is low?

This is a question we get asked quite frequently and patients often tell us it is a conversation they have with their doctor.  So, statins are lipid-lowering drugs, used to help bring down levels of cholesterol and triglycerides in the blood, and it does this by inhibiting protein synthesis.  The reason you are taking statins after a cardiac event or if your cholesterol is high is because the lower the rate in which atherosclerosis forms; the lower the LDL cholesterol, the less likely it is to oxidise and damage a coronary artery.  You may have a low cholesterol, but once you stop taking them your cholesterol synthesis will return to normal, taking your cholesterol in to the higher ranges.
