Effect of mental stress on hemodynamics and left ventricular diastolic function in @entity1 with XXXX .

@entity1032 is an important factor affecting cardiac function. We evaluated the effect of a @entity1032 ( @entity1032 ) test on hemodynamics and left ventricular (LV) diastolic function in @entity1 with @entity741 , and compared the hemodynamic responses with a treadmill exercise test. Fifteen @entity1 were studied. Seven had old @entity583 with significant @entity3979 (group I) and 8 had @entity662 with non-significant @entity3979 (group II). The @entity1032 test was performed as follows: after memorizing 6 random numeral digits, @entity1 repeated these numbers in reverse order for 5 min followed by serial subtraction of 1000 minus 17 for 5 min. Blood pressure (BP) and heart rate (HR) were measured every 1-5 min. Doppler mitral flow velocity (MFV) was recorded every 2-5 min. During the @entity1032 test, BP, HR, and rate pressure product increased by 38.3%, 17.3%, and 62.1% on average, respectively. Early diastolic MFV decreased by 10.0% in group I and 3.3% in group 11. First third filling rate of MFV decreased by 32.3% in group I and 22.8% in group II. A/E ratio increased by 39.3% in group I and 25.8% in group II. These data indicate that the @entity1032 test led to a deterioration in LV diastolic function. The @entity1032 test induced LV @entity67 to a greater extent in @entity1 with significant @entity3979 than in those without significant @entity3979 . @entity741 may be induced by increased left ventricular afterload and/or vasoconstrictive reflex of coronary microcirculation.
