Left ventricular (LV) morphological and functional characteristics in 9 women suffering from pregnancy-induced hypertension (PIH) were studied by means of echocardiograms. In order to distinguish which changes depended on the pressure values and which were the result of pregnancy, 10 nonpregnant control women with no heart disease and 10 normal pregnant women (NP) were studied and the results of each of the groups compared. To evaluate the structure, left ventricular systodiastolic diameters and wall thickness were measured. The only statistically significant difference was in the diastolic diameters between the PIH (4.7 +/- 0.3 cm) and the control group (4.4 +/- 0.2 cm) p less than 0.01. Left ventricular mass was significantly increased (p less than 0.01) in the PIH patients (185 +/- 53.1 g) compared to the NP patients (161 +/- 29.6 g) and the control group (125 +/- 17.4 g). No statistically significant differences were found in the radius thickness ratio in the three groups. The systolic function assessed by the shortening percentage was significantly lower (p less than 0.05) in the control group (32.8 +/- 4.4%) and in the NP patients (37.8 +/- 5.2%) than in the PIH group (39 +/- 6.5%). Afterload assessed by isovolumic period stress was significantly greater (p less than 0.01) in the PIH patients (157 +/- 10.6 dyne/cm2) compared with the NP group (118.9 +/- 7.01 dyne/cm2). There were no significant differences between the first group and the control group (134.09 +/- 8.7 dyne/cm2). As evidence of the diastolic function, analysis was made, on the one hand, of diastolic isovolumic period length (DIP).(ABSTRACT TRUNCATED AT 250 WORDS)
