0470 : Serum IF1 concentration as a predictor of mortality in coronary heart disease patients

Aim The ecto-F1-ATPase/P2Y13 pathway plays a key role in reverse cholesterol transport. Exogenous IF1, known as the natural mitochondrial specific inhibitor of F1-ATPase activity, inhibits ecto-F1-ATPase activity and decreases HDL-C uptake by hepatocytes. We previously found that IF1 is present in human serum and is negatively associated with coronary heart disease (CHD). Here, we investigated the relationship between serum IF1 concentration and mortality in CHD patients. Methods Serum IF1 was measured in 624 CHD patients aged 45-74 from the GENES (Genetique et ENvironement en Europe du Sud) study. After 9.1 years follow up, mortality rate was 24.5%. Results Patients who had died were older…
