Immune mechanisms have important roles in the pathogenesis of atherosclerosis. The present study was conducted to evaluate the association of pulse wave velocity (PWV) with either hepatitis C or B. In 7514 subjects, we determined the PWV, as well as the plasma levels of hepatitis B virus antigen and antibody and of hepatitis C virus antibody. The results of multiple regression analysis showed that seropositivity for hepatitis C virus was a significant variable for PWV independent from atherosclerotic risk factors. Thus, hepatitis C virus seropositivity was associated with increased PWV.

This study was designed to detect patients with type I silent myocardial ischemia (SMI) at rest by assessing the symmetry of the electrocardiographic (ECG) T wave using the spatial velocity electrocardiogram (SVECG). In this study, the ECG T waves in patients with SMI were symmetric compared with those in normal subjects, and the the c/a ratio in the SVECG-T wave as the index of degree of symmetry of the ECG T wave enabled us to diagnose 73% of these patients; the c/a ratio in the SVECG T wave was a useful index for detecting patients with type I SMI at rest.
