Acute pulmonary edema complicating myocardial infarction: is colour M-mode Doppler of the mitral valve a valuable tool?
OBJECTIVE
To assess the value of colour M-mode Doppler of the mitral valve in patients with acute myocardial infarction complicated by pulmonary edema.


METHODS
Case-control, clinical.


METHODS
Coronary care unit in a university hospital.


METHODS
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.
