Association between plasma homocysteine levels and coronary artery disease: a population-based study in northern Greece.

Objective: Elevated plasma total homocysteine (tHcy) levels constitute a risk factor for coronary artery disease (CAD). We prospectively examined the association of fasting tHcy levels in patients in Northern Greece who had established CAD.

Patients And Methods: Plasma fasting tHcy levels were measured in 42 patients with angiographically documented CAD and compared to 42 age-, sex-, BMI- and smoking habit-matched control subjects.
