Abstract

Excessive left ventricular (LV) mass (LVM) increase results in inefficient LV work with high energy waste and a negative prognostic effect. We aimed to investigate the presence of inappropriate LVM and to calculate the myocardial mechanoenergetic efficiency index (MEEi) in asymptomatic women with a history of early-onset (EO) or late-onset (LO) pre-eclampsia (PE). Among all women diagnosed with PE in the years 2009-2013, after applying inclusion/exclusion criteria and cost-effectiveness analysis, we randomly selected thirty women who experienced EO-PE, thirty with a previous LO-PE and thirty healthy controls to undergo echocardiography from 6 months to 4 years after delivery. Data regarding gestational age (GA) and mean uterine artery (UtA) pulsatility index (PI) at PE onset were collected from medical records. All women were free from cardiovascular risk factors. LVM excess was calculated as the ratio between observed LVM and predicted LVM (by sex, stroke work and height), while MEEi was calculated as the ratio between stroke work and “double product” (to approximate energy consumption), indexed to LVM. Concentric remodeling was present in 60% of EO-PE and 53% of LO-PE. LVM excess was significantly more often present in the EO-PE group than in the control group. LVM was inappropriate in 52% of EO-PE and 17% of LO-PE. MEEi showed a tendency towards lower values in the EO-PE group. Multivariate regression analysis showed that both LVM excess and MEEi were independently associated with lower GA and higher mean UtA PI at PE onset. Inappropriate LVM with a tendency towards reduced MEEi in the first 4 years after delivery may partially explain the elevated cardiovascular risk in former pre-eclamptic women compared to the general population.
