OBJECTIVES The aim of this study was to determine whether short-term treatment with perhexiline improves cardiac energetics, left ventricular function, and symptoms of heart failure by altering cardiac substrate utilization.BACKGROUND Perhexiline improves exercise capacity and left ventricular ejection fraction (LVEF) in patients with
This study suggests that pregnancy is associated with a premature deterioration in RV function in women with a systemic RV. These women are also more symptomatic, with a greater reduction in functional class compared with patients with a systemic RV who do not undergo pregnancy. This study will allow this cohort of women to be more accurately counseled as to the potential long-term risks of pregnancy.
The small number of patients with a Fontan circulation in our study was able to tolerate bosentan for 6 months. The safety and tolerability of bosentan in a larger patient population remains unknown. The results presented here justify further investigation in larger studies.
Heart disease is the leading cause of maternal mortality in the UK. Deaths from acquired conditions such as ischaemic heart disease are increasing and often occur in patients with no history of heart disease, thus emphasising the need for vigilance for risk factors in women of childbearing age. All women with known heart disease should have pre-pregnancy counselling to assess for maternal and fetal risk. Women deemed to be at moderate or high risk should be under the care of a specialist antenatal team with experience of managing women with heart disease in pregnancy. Conditions that are considered particularly high risk (mortality >10%) include Marfan syndrome with dilated aortic root, severe left heart obstructive lesions, pulmonary hypertension, and severe left ventricular dysfunction. This article reviews the management of women with heart disease during pregnancy, labour and in the puerperium.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
