Cholesterol is made up of ‘good’ lipoprotein (HDL-C) and ‘bad’ lipoproteins (LDL-C). Keeping them in balance is important for your heart health. Having a higher level of bad cholesterol (LDL-C) can lead to narrowing of the arteries, heart attack, stroke, mini-stroke (TIA). This is because if left untreated, bad cholesterol can build up in the artery wall and cause blockages. Statin medication can help regulate cholesterol levels but in some instances this is not enough and for that reason further research is required. We regularly conduct clinical studies into high cholesterol and cardiovascular diseases. If you have been diagnosed with high cholesterol, please select from the studies below to see if you are eligible to take part.
