dc.description.abstract | Objectives: To identify differences in cardiac hemodynamic changes between the Valsalva maneuver and nitroglycerin (NTG) administration. Methods: Fifty-three subjects (37 men, 43 +/- 12 years) with normal cardiac function [left ventricular ejection fraction >= 55%, early to late mitral inflow velocity ratio (E/A) >= 1, left atrial volume index <= 34 ml/m(2) and early diastolic mitral annulus velocity (E') >= 8 cm/s] were enrolled. Doppler parameters were determined at rest, during the Valsalva maneuver and after NTG administration. Results: Decreased E, A and E/A were observed both during the Valsa Iva maneuver and after NTG administration (p < 0.0001 for all). However, the reduction in E (Delta E-valsalva: -30 +/- 16 cm/s vs. Delta E-NTG: -17 +/- 17 cm/s) and E/A (Delta E/A(Valsalva): -0.37 +/- 0.28 vs. Delta E/A(NTG): -0.19 +/- 0.25) and the prolongation of the deceleration time (DT) of E (Delta DTvalsalva: 105 +/- 74 ms vs. Delta DTNTG: 83 +/- 63 ms) were more prominent during the Valsalva maneuver than with NTG administration (p < 0.0001 for all). Particularly, a greater decrease in E' was observed during the Valsalva maneuver (Delta E'(Valsalva): -3 +/- 2 cm/s vs. Delta E'(NTG): -2 +/- 2 cm/s, p < 0.0001). Eighteen subjects (34%) showed Iota E/A >= 0.5 during the Valsalva maneuver; thus, they were mislabeled as 'pseudonormal', while only 3 subjects (6%) showed Delta E/A >= 0.5 after NTG administration. Conclusions: The Valsalva maneuver not only decreases preload but also affects myocardial performance, thus, its use can result in the mislabeling of normal subjects as pseudonormal. (C) 2014 S.
