[The Impact of Asymptomatic Left Ventricular Dilatation on the Course of Anterior Myocardial Infarction.]

AIM: to elucidate effect of asymptomatic left ventricular (LV) dilatation on the course of myocardial infarction (MI).

MATERIAL AND METHODS: LV remodeling and diastolic function, as well as inter- and intraventricular asynchrony were studied in 58 patients with primary anterior MI without signs of heart failure and ejection fraction >40% on month 12 of the disease. Patients were divided into 2 groups: with normal-sized left ventricle (LV end diastolic size [EDS] <5.5 cm) (n=28), and with mild LV dilatation (LV EDS 5.6-5.9 cm) (n=30).

RESULTS AND CONCLUSION: At month 12 of MI patients with asymptomatic LV dilatation were characterized by more pronounced signs of pathological remodeling, diastolic LV dysfunction, inter- and intraventricular asynchrony.
