Objective: To assess the value of colour M-mode Doppler of the mitral valve in patients with acute myocardial infarction complicated by pulmonary edema. Design: Case-control, clinical. Setting: Coronary care unit in a university hospital. Patients/Subjects: 28 patients admitted because of acute myocardial infarction, and who developed pulmonary edema(group P, cases); 39 patients with uncomplicated myocardial infarction(group C, controls). Results: Patients in group P showed higher E wave(77± 20 vs. 64± 16 cm/s, p=0.007), E/A ratio(1.5± 1.0 vs. 1.0± 0.4, p=0.014), lower time of deceleration of the E wave(153± 40 vs. 196± 53 ms, p=0.001) and lower Ejection Fraction(35± 10 vs. 49± 11, p< 0.001). There were no differences in the velocity of the colour M-mode Doppler of the mitral valve(Vp: 36.2± 11 vs. 34.0± 12 cm/s). Excluding patients with abnormal relaxation or restrictive pattern of the pulsed Doppler, Vp was identical(group P 34± 10, group C 34± 12). Conclusions: M-mode colour Doppler of the mitral valve was not useful to differentiate patients with acute pulmonary edema complicating myocardial infarction. Measurement of Vp is not warranted as a routine in these patients.
Objective: To assess the value of color M-mode Doppler of the mitral valve in patients with acute myocardial infarction complicated by pulmonary edema. Design: Case-control, clinical. Settings: Coronary care unit in a university hospital. Patients / Subjects: 28 Patients with because of elevated myocardial infarction, and who developed pulmonary edema (group P, cases); 39 patients with uncomplicated myocardial infarction (group C, controls). Results: Patients in group P showed higher E wave (77 ± 20 vs. 64 E / A ratio (1.5 ± 1.0 vs. 1.0 ± 0.4, p = 0.014), lower time of deceleration of the E wave (153 ± 40 vs. 196 ± 53 ms, p = 0.001) and lower Ejection Fraction (35 ± 10 vs. 49 ± 11, p <0.001). There were no differences in the velocity of the color M-mode Doppler of the mitral valve (Vp: 36.2 ± 11 vs. 34.0 ± 12 cm / s). Excluding patients with abnormal relaxation or restrictive pattern of the pulsed Doppler, Vp was identical (group P 34 ± 10, group C 34 ± 12). Conclusions: M-mode co lour Doppler of the mitral valve was not useful to differentiate patients with acute pulmonary edema complicating myocardial infarction. Measurement of Vp is not warranted as a routine in these patients.
