Letter to the Editor

Dear Sir,

On behalf of the author group, we would hereby like to thank Demirkol et al. for their valuable comments. In our previous study [1], we reported the relationship among various risk factors evaluated in venous blood samples of study participants who underwent coronary angiography for the presence of coronary artery disease (CAD). In this study [2] our aim was to determine whether arterial blood samples withdrawn from femoral arteries during standard Judkin’s technique could be used for the evaluation of some biochemical parameters in CAD patients and controls. For practical reasons, the fasting blood samples of 73 CAD patients and 50 controls were obtained just before coronary angiography starting from 8 o’clock in the morning. Attention was paid to collecting arterial and venous blood samples of each person at the same time in the morning after a 12 h fast.
