OBJECTIVE: To evaluate the post-partum maternal cardiac function in patients with history of severe preeclampsia. METHODS: A series of women with previous singleton pregnancy complicated by severe preeclampsia underwent transthoracic echocardiography at 6-12 months from delivery. A group of women with previous uncomplicated pregnancy was selected as controls. RESULTS: Sixteen women with history of severe preeclampsia were enrolled in the study group whereas 18 patients were selected as controls. In the study group systolic (p=0.002) and diastolic blood pressure (p=0.044) were significantly higher. Significant differences were observed in systolic left ventricular (LV) parameters, such as cardiac output (p=0.034), LV mass indexed to BSA (p=0.024) and longitudinal contraction, expressed by tissue Doppler (TD) S1 wave, which resulted relatively impaired in former preeclamptic women (p=0.049). As regards as diastolic parameters, pulsed Doppler A-wave velocity was increased (p=0.036). TD E-wave velocity was significantly lower in study group (p<0.001) and E/E1 ratio (E=peak early diastole transmitral wave velocity/E1=peak early diastolic velocity at mitral valve annulus at TD) was higher respect to controls (p<0.001). CONCLUSIONS: LV contractility and diastolic function, although within normal reference ranges, show slight but significant impairment among women who experienced a severe preeclampsia. TD seems to be a sensible tool to identify these precocious signs of potential LV dysfunction.
