“…This discrepancy may be explained in part by the age criterion in the different studies. Van Dam et al [11] and Mehta et al [12] examined a wide range of ages (1-65 and 22-64 years, respectively), whilst we focused on the range of 48-60 years -the early postmenopause -a span in which the gender differences may be more evident, as suggested by Voutilainen et al's study [19]. How can the higher aortic flow and hemodynamic parameters in early postmenopausal women as compared with age-matched men be explained?…”

Objective. Exercise Doppler echocardiography has been recognised as an accurate method for the assessment of left ventricular function in patients with coronary artery disease. Gender differences in aortic flow parameters during exercise have not been well established. The aims of this study were to compare basal ejection Doppler indexes in healthy early postmenopausal women with those of men, and to assess the effects of both isometric and dynamic exercises on these parameters. Design. Intergroup comparison between early postmenopausal women and middle-aged men Subjects. Fifteen healthy women with a mean age of 55 (SD 5) years and 15 healthy men aged 52 (SD 4) were evaluated.Setting. Women were recruited from a menopause clinic and men from a primary cardiovascular prevention program at a cardiac rehabilitation institute. Interventions. Isometric exercise was performed with a 2-hand bar dynamometer, and dynamic exercise with a supine ergometer. Echo Doppler examination was performed at rest and at peak isometric and dynamic exercise with a pulsed Doppler transducer. Results. Both types of exercise resulted in higher values of hemodynamic parameters in the women, with most figures reaching statistical significance. Most aortic flow parameters during rest and exercise were also significantly higher in the women. Conclusions. The unexpected higher values in hemodynamic and aortic flow parameters in early postmenopausal women as compared with middle aged men may shed light on a peculiar aspect of gender differences in cardiovascular function, perhaps specific to this age group and related to menopausal transition.

Effects of aging on cardiac blood flow velocities

The effects of aging on cardiac blood flow velocities are important as a description of the natural history of the aging process and as a reference for evaluation of the aging cardiovascular system. We therefore studied these effects in 215 healthy volunteers, 120 males and 95 females, between 1 and 65 years old. Pulsed Doppler signals were recorded proximal and distal to the mitral (M) and tricuspid (T) valves, in the left ventricular outflow tract (LVOT), in the ascending aorta (AAO), in the right ventricular outflow tract (RVOT), and in the pulmonary artery (PA). Systolic (S) flow velocity patterns consist mainly of one peak. Diastolic blood flow velocity is characterized by two peaks: one due to early filling (E) of the ventricle and a second as a result of atrial contraction (A). All peaks are characterized by the maximum of the median velocity curve (Vmax). With age increasing from 1 to 65 years, VmaxS decreases in the AAO (40%) and PA (10%), VmaxE decreases on both sides of the M valve (proximal-50%; distal-30%), and the T valve (proximal-20%; distal-30%). However, with increasing age VmaxS increases in the LVOT (25%), and VmaxA increases on both sides of the M valve (proximal-20%; distal-50%) and proximal to the T valve (30%). VmaxS in the RVOT and VmaxA distal to the T valve did not show a relation with age. These observations demonstrate that in a normal population Vmax in the heart and great vessels is age dependent at most sites.(ABSTRACT TRUNCATED AT 250 WORDS)
