Abstrakt: Changes in left ventricular volume after a first myocardial infarction were studied in 50 patients. Serial radionuclide andiograms were obtained 48 h, 10 days and 1 and 6 months after infarction and left ventricular volume measured by a nongeometric method. Left ventricular dilation (≥20% increase in end-diastolic volume) occurred within 10 days of infarction in 11 patients, who had a mean volume increase of 34 ± 15% (p = 0.002 versus 48 h) at 10 days and 61 ± 43% (p = 0.01 versus 10 days) at 6 months. Ten other patients manifested left ventricular dilation between 10 days and 6 months with a lesser volume increase of 42 ± 18% by 6 months.
