Plain English Summary

Background and study aims
The cells in the human body contain DNA, complex chemical that carries genetic information. DNA is made up of small, ‘X’ shaped structures which are responsible for specific genes (chromosomes). At the ends of the chromosomes are stretches of DNA called telomeres, which protect the genetic material by preventing the DNA from fraying and unravelling, like the plastic tips on the end of shoe laces. As cells reproduce (copy themselves into two identical cells), the telomere caps become shorter, which is linked with the process of aging (at a cellular level). When the telomeres become too short to do their job properly, the cells can no longer divide and so becomes inactive (senescent) or dies. This shortening process is associated with aging, cancer, and a higher risk of death. Recent studies have shown that there is a connection between the processes of telomere shortening and the development of cardiovascular disease (disease of the heart and blood vessels). Telomerase is a protein which can help to prevent telomere shortening by lengthening telomeres in certain types of cells. By increasing the activity of telomerase, it could be possible to help slow down cellular aging, and prevent the development of diseases such as cardiovascular disease. The aim of this study is to find out whether atorvastatin (a cholesterol lowering drug) and perindopril (a blood pressure lowering drug) can help to increase telomerase activity in patients with high cholesterol and high blood pressure with no signs of significant cardiovascular disease.

Who can participate?
Adults aged between 35 and 75 years with high cholesterol can take part in part one and adults aged between 35 and 75 years with high blood pressure and no known diabetes or heart disease can take part in part two.

What does the study involve?
In part one of the study, 100 participants with high cholesterol are randomly allocated to one of two groups. Those in the first group are treated with 20mg atorvastatin every day for 12 months. Those in the second group do not receive any medication for the two months of the study. In part two of the study, 52 participants with high blood pressure are randomly allocated to one of two groups. Those in the first group are treated with 5-10mg of perindopril daily for 12 months as well as any diuretics (water tablets) needed to control their blood pressure (if necessary). Those in the second group are treated using standard medications used to treat high blood pressure for 12 months. At the end of the study, participants in both groups of each part of the study have blood and urine samples taken so that they can be assessed in the lab for signs of telomerase activity.

What are the possible benefits and risks of participating?
There are no direct benefits to participants. There is a small risk that participants may experience pain and bruising following blood tests.

1. Hypercholesterolemia
2. Hypertension


Part one - Atorvastatin arm:
Participants are randomized (using of a table of random numbers) to one of two groups in a 1:1 ratio.

Intervention group: Participants receive 20mg atorvastatin daily for 12 months.
Control group: Participants do not receive any additional medication in the 12 month study period.

Part two - Perindopril arm:
Participants are randomised (using of a table of random numbers) to one of two groups in a 1:1 ratio.

Intervention group: For 12 months participants receive 5-10 mg of perindopril once or twice a day as monotherapy or in combination with diuretics to achieve target levels of blood pressure.
Control group: For 12 months participants receive other antihypertensive drugs: beta-blokers, calcium antagonists, diuretics to achieve target levels of blood pressure. In this group inhibitors of renin-angiotensin-aldosterone system are prohibited.
