Description of intervention(s) / exposure
Three subject groups will be recruited. Group 1; twenty healthy fit young adult males aged 20 – 25 years, free of cardiovascular risk factors and with no family history of cardiovascular disease. Group 2; twenty healthy fit older adult males aged 40-60 years with no history (or family history) of cardiovascular disease. Group 3; Twenty male patients recently diagnosed with overt coronary artery disease aged 40-60 year about to start statin drug therapy. None of the subjects in each of the three groups shall have received prior statin therapy. All subjects will receive statin therapy for one week but group 3 subjects will continue thereafter for a period of at least 6 months. An overnight fasted blood sample will be obtained at 0800hrs from all subjects immediately prior to receiving Atovastatin 40mg daily (oral tablet). Additional overnight fasted blood samples will be drawn from all subjects at 0800hrs on days 1, 2 and 7 following initiation of statin therapy. Adherence to drug schedule will be assessed by drug tablet return. Further monthly blood samples will be obtained from group 3 subjects for 6 months. Blood samples will be analysed for lipids (triglycerides, total cholesterol, LDL and HDL), creatinine, high sensitivity C reactive protein (hsCRP), CNP and NTproCNP content. Subjects in groups 1 and 2 with baseline triglyceride > 1.7 mmol/L will be excluded.

Outcomes
Primary outcome [1] 289530 0
Analyse the relative changes in plasma concentrations of NTproCNP following statin treatment in the three groups. Group 1; twenty healthy fit young adult males aged 20 – 25 years. Group 2; twenty healthy fit older adult males aged 40-60 years with no history (or family history) of cardiovascular disease. Group 3; Twenty male patients recently diagnosed with overt coronary artery disease aged 40-60 year about to start statin drug therapy.
Timepoint [1] 289530 0
Baseline, Days 1, 2 and 7 of statin treatment (Groups 1,2 and 3). Months 1-6 of statin treatment for Group 3.
Secondary outcome [1] 302694 0
Determine the relationship of plasma NTproCNP concentrations to plasma lipid markers and high sensitivity C reactive protein.
Timepoint [1] 302694 0
Baseline, Days 1, 2 and 7 of statin treatment (Groups 1,2 and 3). Months 1-6 of statin treatment for Group 3.
