RESUMO
OBJECTIVE:
To assess structural and functional cardiac changes in asymptomatic pregnant women with chronic arterial hypertension (CAH).METHODS:
One hundred pregnant women with CAH underwent conventional Doppler echocardiography. The Student t test was used to compare them with 29 normotensive pregnant women (NT) in their third gestational trimester.RESULTS:
Systolic (SBP; mmHg) and diastolic (DBP; mmHg) blood pressure values were higher (p<0.001) in the CAH pregnant women (SBP 139±19 and DBP 92± 18) as compared with those of the NT group (SBP 112±10 and DBP 74±9). A significant enlargement of the left atrium (4.10±0.48 cm vs 3.6±0.3 cm; p<0.001) and of the left ventricular normalized mass (59.6±19.7 g/cm2,7 vs 41.9±3.4 g/cm2,7; p<0.001) was observed. Cardiac output (CO, L/min) and systolic volume (SV, mL) were significantly higher in the CAH group (CO 6.0±1.54 vs 4.9±2.1, p<0.01; SV 77.3±19.8 vs 56.5±25.8, p<0.001).CONCLUSION:
Chronic hypertensive pregnant women have structural and functional cardiac changes that justify routine cardiologic assessment, even in the absence of cardiopulmonary symptoms
