- Brief Summary
Coronary heart disease (CHD) is one of the diseases characterised by biological aging as one of the important risk factors in several epidemiological studies. The mean telomere length and telomerase activity serve as markers for the biological age at the cellular level, with shorter telomeres and lower telomerase activity defining the increased biological age. Telomere length and telomerase activity, therefore, correlates with the risk of CHD and atherosclerosis. A present study states that the treatment with a statin is associated with a reduction in the number of clinical events but only in individuals with increased risk based on their telomere length. This suggests a positive relationship of telomere and telomerase system with the treatment with statins in CHD patients.
- Detailed Description
Coronary heart disease (CHD) is identified as one of the diseases characterised by biological aging as one of the important risk factors in several epidemiological studies. Premature biological aging is distinct from chronological aging and may predispose the individual to myocardial infarction, atherosclerosis and CHD in particular. The mean telomere length and telomerase activity serve as markers for the biological age at the cellular level, with shorter telomeres and lower telomerase activity defining the increased biological age. Telomere length and telomerase activity, therefore, correlates with the risk of CHD and atherosclerosis. Statins serve as the drugs of obvious choice based on their well established efficacy and safety profiles for the treatment of CHD and associated atherosclerosis. A present clinical study states that the treatment with a statin is associated with a reduction in the number of clinical events but only in individuals with increased risk based on their telomere length. This suggests a positive relationship of telomere and telomerase system with the risk of CHD and, therefore, would help clinicians to categorise the patient populations based on their leucocyte telomere length for treatment with statins.

- Primary Outcome Measures
Name Time Method Change from baseline in telomere length after different dose statin treatment baseline; 4 and 24 weeks telomere length of circulating leukocyte will be measured by Southern blot test before and after treatment
- Secondary Outcome Measures
Name Time Method PCI-related myocardial infarction (MI) PCI-related MI will be assesed within 24 hours after the end of the coronary artery stenting procedure PCI related myocardial infarction is defined by the third Universal definition of myocardial infarction
Change from baseline in telomerase activity after different dose statin treatment baseline; 4 and 24 weeks telomerase activity of circulating leukocyte will be measured by Southern blot test before and after treatment
