[The index of left ventricle dilatation estimated with echocardiography in infarct patients].

The Authors have introduced, for functional valuation of the left ventricle in infarcted patients, an echocardiographic new parameter: the index of dilatation (ID). This index constantly show oneself increased in all infarcted patients that clinically show marks of the cardiac decompensation, also when the Vcf and Fe show modest alterations. According to the Authors, the ID have in report with the PTDVS and constitute and important evidence of the left ventricular working controllable in the time.
