    Journal: Ter Arkh; 2005; 77(12):22-5. PubMed ID: 16514814.
    Abstract:
    AIM: To study blood flow along the internal jugular veins (IJV) in the initial state and under the action of nitroglycerin in patients with essential arterial hypertension (EAH) with reference to characteristics of a 24-h profile of blood pressure. MATERIAL AND METHODS: A 24-h monitoring of blood pressure (MBP), duplex scanning of IJV, venous IJV outflow were studied in 26 patients with EAH stage 2 (mean age 39 +/- 5.0) before and after sublingual intake of nitroglycerin (0.5 mg). RESULTS: By 24-h MBP findings, two groups of patients were identified: with unaffected blood pressure profile (group 1) and affected profile (group 2). Nitroglycerin produced a unidirectional reaction of IJV (increased outflow) in group 1 and multidirectional changes of venous outflow along the IJV in patients of group 2. CONCLUSION: Nitroglycerin test showed different venous cerebral hemodynamics in EAH patients with different variants of 24-h MBP.
