Key result
Severe preeclampsia was associated with significant cardiac alterations compared to healthy pregnancies, including increased left ventricular mass (146.63 vs 128.69 g; p=0.033).
Why the study?
The study was conducted to compare electrocardiographic and echocardiographic changes between patients with severe preeclampsia and those with uncomplicated pregnancies.

Severe preeclampsia is associated with significant structural cardiac changes, including increased left ventricular mass and relative wall thickness, suggesting a chronic remodeling process.
ECG changes in severe PE may warrant closer monitoring; leaves open whether they predict outcomes in larger cohorts.
BACKGROUND: The aim of the current study is to compare electrocardiographic and echocardiographic changes in patients with severe preeclampsia (PE) and those with uncomplicated pregnancies. METHODS: This is a case-controlled prospective study consisting of 21 pregnant women with severe preeclampsia and a control group consisting of age- and gestational age-matched 24 healthy pregnant women. All patients underwent electrocardiographic and echocardiographic investigation. RESULTS: QRS intervals were shorter and PR intervals were longer in the PE group (QRS duration: 80 (60-120) ms and 80 (40-110) ms, p=0.035; PR duration: 160 (100-240) ms and 120 (80-200) ms, respectively; p=0.046). The left ventricular end-systolic diameters of the patients with severe PE group were significantly larger than the control group (31 (24-36) mm and 30 (24-33) mm, respectively; p=0.05). Similarly, posterior wall thickness values of the PE group were significantly higher compared to the control group (9 (7-11) mm vs. 8 (6-10) mm, respectively; p=0.020). Left ventricular mass (146.63±27.73 g and 128.69±23.25 g, respectively; p=0.033) and relative wall thickness values (0.385±0.054 and 0.349±0.046, respectively; p=0.030) were also higher in the PE group. In addition, patients with early-onset severe PE had significantly a higher left ventricular end-diastolic diameter and volume compared with late-onset PE patients. CONCLUSIONS: The structural changes detected in the severe PE group suggest a chronic process rather than an acute effect. In addition, diastolic dysfunction and left ventricular remodeling are most marked in patients with severe early-onset PE.
