title: [Predictive value of various echocardiographic parameters of systolic and diastolic function in the development of congestive heart failure after infarction].
abstract: To evaluate the predictive value of systolic and diastolic left ventricular (LV) function parameters, in the development of congestive heart failure (CHF) after acute myocardial infarction (AMI), 48 patients (mean age 56.2 +/- 10.4 years) were studied with two-dimensional and Doppler echocardiography (2D echo) in the acute phase (36 +/- 12 hours) and after 6 months of follow-up. The following parameters have been evaluated: LV wall motion score-index; peak velocity of early diastolic filling (E); peak velocity of filling during atrial systole (A); the ratio A/E; percent of LV filling contributed by atrial systole (A%). During follow-up 10 patients (Group B; 21%) developed symptoms and/or signs of CHF, while 38 patients (Group A; 79%) did not. In the patients who developed CHF 2D echo showed a depressed contractile function (mean value of wall motion score-index 3.08 +/- 0.45 versus 3.53 +/- 0.32 of Group A; p < 0.001) and a marked impairment of filling during atrial systole: A/E = 1.89 +/- 0.80 versus 1.07 +/- 0.35 (p < 0.001); A% = 52.2 +/- 9.9 versus 39.1 +/- 8.4 (p < 0.001). The multivariate analysis showed that the ratio A/E, A% and the wall motion score-index are the only variables that may predict the development of CHF. This capacity has been confirmed also considering the cut-point as conditional variables (A/E > 1.4; A% > 45%; score-index < 3.1). Our results demonstrate that a combined evaluation by 2D echo of systolic and diastolic LV function parameters allowed a better stratification of patients at risk of developing CHF after an AMI.
