[Hypokinetic cardiomyopathy. A possible result of myocardial contusion].
Myocardial contusion is a frequent complication of blunt chest trauma. Ventricular involvement is generally segmental and exhibits a favourable evolution. We describe the case of a 44-year-old male who suffered an acute blunt thoracic injury with a consequent stable worsening of his functional class. His first electrocardiographic examination 30 days after the trauma showed negative T wave in V3-V6 leads while one and two-dimensional echocardiography exhibited a diffuse damage of the morphology of the left ventricle and a lowering of the fractional shortening (FS) of its end-diastolic diameter (EDD): FS = 23%, EDD = 6.9 cm, diastolic eccentricity index = 65%, systolic eccentricity index = 70%. During a follow-up period of thirteen months ECG became normal after a short time while the echocardiogram maintained its initial abnormalities and the patient maintained his compromised functional class. We report this peculiar pattern of myocardial contusion evolution which has not previously been described.
