title: Eosinophil counts and plasma fibrinogen in patients with vasospastic angina pectoris.
abstract: Epidemiologic studies have suggested a relation between white blood cell (WBC) counts and the incidence of coronary heart disease. However, the relation between vasospastic angina pectoris (VAP) and WBC counts remains to be elucidated. To clarify the relation between differential and WBC counts in VAP, we compared the hematologic values, blood chemical values, plasma fibrinogen levels, C-reactive protein levels, and coronary risk factors in patients with spontaneous attacks of VAP (n = 39) with those in patients with stable effort angina pectoris (EAP, n = 35) and in control subjects (n = 19). Patients with VAP were further divided into mild VAP (n = 22) and severe VAP groups (n = 17). There were no differences in the coronary risk factors, body temperature, total WBC counts, and C-reactive protein levels among the control, EAP, mild VAP, and severe VAP groups, except that the high-density lipoprotein cholesterol in the EAP group was significantly lower than that in the control group (p <0.01). In contrast, the eosinophil counts were significantly higher in the severe VAP group than in the other 3 groups (p <0.01). Plasma fibrinogen levels were also significantly higher in the severe VAP group than in the other 3 groups (p <0.05). The follow-up study for differential and WBC counts in patients with VAP (n = 23) demonstrated that, after medical therapy, the eosinophil counts were significantly decreased to the some level as those in the control group (p <0.0001). Thus, the eosinophil counts and plasma fibrinogen levels could predict the severity of VAP. Furthermore, a follow-up study in patients with VAP suggests that coronary vasospasm could result in an increase in eosinophil counts.
