ABSTRACT
INTRODUCTION AND OBJECTIVES: Cardiovascular disease is a common cause of morbidity and mortality in pregnant women. Arrhythmias are common complications during pregnancy; however, the data are limited. Our goal was to characterize the epidemiology, clinical presentation, and impact of cardiac arrhythmias on maternal-fetal outcomes. METHODS: A prospective cohort study from the Colombian Registry of Pregnancy and Cardiovascular Disease was carried out from 2016 to 2019. All patients with tachyarrhythmia or bradyarrhythmia and a minimum follow-up of six months after delivery were included. The primary outcome was a composite of cardiac events defined as pulmonary edema, symptomatic sustained arrhythmia requiring specific therapy, stroke, cardiac arrest, or maternal death. Secondary outcomes were other cardiac, neonatal, and obstetric events. RESULTS: Arrhythmias were the most common cause of referral to our dedicated cardio-obstetric clinic. A total of 92 patients were included, mean age 27±6 years; 8.7% had previous structural heart disease, and cardiology consultation was delayed in 79.4%. The most common arrhythmias were premature ventricular contractions (33%) and paroxysmal reentrant supraventricular tachycardias (15%); 11 patients (12%) had cardiac implantable electronic devices. Cardiac events occurred in 18.4% of patients, obstetric events occurred in 6.5%, and one caesarean was indicated in the context of symptomatic severe mitral stenosis. Adverse neonatal outcomes were observed in 24.3% of newborns. CONCLUSIONS: Arrhythmias were the most common cause of referral to a dedicated cardio-obstetric clinic; most had a benign course. Adverse maternal cardiovascular outcomes were significant and there was a high rate of obstetric and neonatal adverse events, underlining the importance of multidisciplinary care.

Introducción: el hígado cumple múltiples funciones en la coagulación sanguínea. En enfermedad hepática, por ejemplo, se altera la hemostasis sanguínea, situación que se manifiesta como hipercoagulabilidad en algunos pacientes o sangrado excesivo en otros. Propósito: revisar la evidencia actual sobre alteraciones en la coagulación de los pacientes con cirrosis. Métodos: se llevó a cabo una búsqueda utilizando los términos "MESH": blood coagulation disorders, cirrhosis, hemostasis, hypercoagulability, bleeding y blood coagulation tests. Se escogieron aquellos artículos cuyos títulos y abstracts se adaptaran mejor al propósito de esta revisión. Resultados: de 146 artículos se seleccionaron 76 para la elaboración del presente escrito. Conclusión: a pesar de las diversas alteraciones que presentan los pacientes cirróticos en la coagulación, el sistema hemostásico se encuentra en un nuevo balance que las pruebas de coagulación utilizadas rutinariamente no reflejan; es por esto que no son herramientas útiles para la predicción del riesgo de sangrado o de complicaciones trombóticas.
In liver disease one of the liver's functions related to blood coagulation, hemostasis, is disturbed. This manifests as hypercoagulability in some patients and as excessive bleeding in others. Objective: The objective of this study was to review current evidence about blood coagulation disorders in cirrhotic patients. Methods: We conducted a search using the following "MESH" terms: blood coagulation disorders, cirrhosis, hemostasis, hypercoagulability, bleeding and blood coagulation tests. From the results articles whose titles and abstracts best fit with the aim of this review were chosen. Results: From 146 articles obtained, 76 were selected and used to construct this article. Conclusion: Despite the diverse blood coagulation disorders present in cirrhotic patients, the hemostatic system accomplishes a new balance that currently used blood coagulation tests fail to show. This is the why these cannot be considered useful tools for predicting the risk of bleeding or thrombotic complications.
