Background:
Prorenin and renin are both involved in atherosclerosis. However, the role of plasma prorenin and renin in the development and progression of coronary artery disease (CAD) is still not clear. Thus, we aimed to examine the relationships among plasma prorenin concentration, CAD and clinical parameters.
Methods:
We measured plasma prorenin and renin concentrations and other parameters in 85 patients who underwent coronary angiography. Patients were divided into a CAD group (≥75 % stenosis in one or more coronary arteries) and a non-CAD group.
Results:
There was a weak correlation between prorenin and plasma renin concentration (r =0.35, p =0.001), and plasma renin activity (r =0.34, p =0.001). There was no significant difference in the plasma prorenin concentration between the CAD group and non-CAD group. However, patients with a high plasma prorenin concentration frequently suffered CAD. Receiver-operating-characteristic curve analysis showed that the optimal cutoff value of plasma prorenin concentration to detect CAD was 1,100 pg/ml, with a positive predictive value of 94 % and a negative predictive value of 36 %.
Conclusion:
The plasma prorenin concentration increases with increases in plasma renin concentration. Higher plasma prorenin concentration (>1,100 pg/ml) plays a role in the development of CAD.
