Antecedentes y objetivos Los cambios cardiovasculares del embarazo conllevan mayor riesgo en cardiópatas. El objetivo fue analizar los efectos adversos cardiovasculares, obstétricos y perinatales asociados a cardiopatía congénita y adquirida durante el embarazo y puerperio.
Materiales y métodos Estudio transversal y retrospectivo, que incluyó el registro de 2017-2023 de pacientes embarazadas o puérperas hospitalizadas con diagnóstico de cardiopatía congénita o adquirida. Se compararon los eventos adversos (insuficiencia cardiaca, evento vascular cerebral, edema agudo pulmonar, muerte materna, hemorragia obstétrica, prematuridad y muerte perinatal) con las variables clínicas y el tratamiento implementado.
Resultados Se incluyeron 112 pacientes con mediana de edad de 28 años (rango 15-44). Predominaron los cortocircuitos 28 (25%). Treinta y seis pacientes (32%) se clasificaron en clase iv de la escala modificada de la OMS para riesgo cardiovascular materno.
Presentaron insuficiencia cardiaca 39 (34,8%), edema agudo de pulmón 12 (10,7%), evento vascular cerebral 2 (1,8%), muerte materna 5 (4,5%), hemorragia obstétrica 4 (3,6%), prematuridad 50 (44,5%) y muerte perinatal 6 (5,4%).
Los cortocircuitos se asociaron con prematuridad (odds ratio [OR] ajustado 4; IC 95%: 1,5-10, p=0,006). La miocardiopatía periparto tuvo un mayor riesgo de edema agudo pulmonar (OR ajustado 34; IC 95%: 6-194, p=0,001) y insuficiencia cardiaca (OR ajustado 16; IC: 95%: 3-84, p=0,001). Se observó un aumento del riesgo de hemorragia obstétrica en pacientes con prótesis valvulares (OR ajustado 30; IC 95%: 1,5-616, p=0,025) y con el uso de ácido acetilsalicílico (OR ajustado 14; IC 95%: 1,2-167, p=0,030). Además, este último se asoció a muerte perinatal (OR ajustado 9; IC 95%: 1,4-68, p=0,021).
Conclusiones Se encontraron complicaciones severas durante el embarazo y puerperio en cardiópatas, por ello es vital la evaluación preconcepcional y la vigilancia estrecha.
Background and objectives Cardiovascular changes during pregnancy carry greater risk in heart disease. We analyze cardiovascular, obstetric and perinatal adverse effects associated with congenital and acquired heart disease during pregnancy and postpartum.
Materials and methods Cross-sectional and retrospective study, which included the 2017-2023 registry of pregnant or postpartum patients hospitalized with diagnosis of congenital or acquired heart disease. Adverse events (heart failure, stroke, acute pulmonary edema, maternal death, obstetric hemorrhage, prematurity and perinatal death) were compared with the clinical variables and the implemented treatment.
Results 112 patients with a median age of 28 years (range 15-44) were included. Short circuits predominated 28 (25%). Thirty-six patients (32%) were classified in class IV of the modified WHO scale for maternal cardiovascular risk.
Heart failure occurred in 39 (34.8%), acute lung edema 12 (10.7%), stroke 2 (1.8%), maternal death 5 (4.5%), obstetric hemorrhage 4 (3.6%), prematurity 50 (44.5%) and perinatal death 6 (5.4%). Shunts were associated with prematurity (adjusted odds ratio 4; 95% CI: 1.5-10, P=.006). Peripartum cardiomyopathy represented higher risk of pulmonary edema (adjusted OR 34; 95% CI: 6-194, P=.001) and heart failure (adjusted OR 16; 95% CI: 3-84, P=.001). An increased risk of obstetric hemorrhage was observed in patients with prosthetic valves (adjusted OR 30; 95% CI: 1.5-616, P=.025) and with the use of acetylsalicylic acid (adjusted OR 14; 95% CI: 1.2-16, P=.030). Furthermore, the latter was associated with perinatal death (adjusted OR 9; 95% CI: 1.4-68, P=.021).
Conclusions Severe complications were found during pregnancy and postpartum in patients with heart disease, which is why preconception evaluation and close surveillance are vital.
