Objectives: In this study the pulmonary venous flow velocity pattern was analysed in 25 hypertensive patients with and without heart failure to clarify whether the pulmonary venous flow velocity pattern provides compensatory information in the interpretation of the mitral flow velocity pattern. Mothods: 25 patients with hypertension were considered for this study. Eight of the 25 patients with hypertension had symptom of congestive heart failure(group 2). Control group fulfilled the following criteria (1) no history of heart disease or hypertension, (2) no hyperlipidemia, (3) normal EKG, chest X-ray, Doppler echocardiographic recordings were made with the subject in the left lateral position during quiet respiration. The pulmonary venous flow velocity pattern and mitral flow velocity pattern were examined in the apical four-chamber view. The isovolumic relaxation time was examined in the apical five-chamber view. Results : The mitral flow velocity pattern in 17 hypertensive patients without heart failure was charaterized by a decreased in the peak early diastolic filling velocity(E, p>0.05), an increased peak filling velocity at atrial contraction(A, p<0.05) and a decreased E/A ratio (p<0,05). The mitral flow velocity pattern was "normalized" in 8 patients with heart failure, with no differences in mitral flow velocity pattern as compared with 13 normal subjects. In patients with heart failure, S wave was lower and D wave was higher and the S/D ratio was lower compared with hypertensive patients without heart failure(p>0,05) and D wave was higher and the S/D ratio was lower compared with control subjects(p<0.05). Conclusion: Analysis of the pulmonary venous flow velocity pattern in conjunction with the mitral flow velocity pattern provieds important and more reliable information in the interpretation of the mitral flow velocity pattern in hypertensive patients with and without heart failure
