Abstract

To test the hypothesis that increasing latency from diagnosis to delivery in patients with preterm hypertensive disorders of pregnancy is associated with an increased maternal risk of cardiovascular admission after delivery. Retrospective cohort from the IBM MarketScan® Commercial Database from 2006 to 2016. Patients age 15-45 years with a preterm delivery complicated by a hypertensive disorder of pregnancy, at least 6 months of continuous insurance coverage prior to delivery and at least 365 days of coverage post-delivery were included. Hospital readmission after delivery for a composite of acute cardiovascular events (cardiomyopathy, heart failure, cardiac arrest, myocardial infarction) or cerebrovascular events. Cox proportional hazards were used to estimate the risk of the primary outcome for each week of latency from diagnosis to delivery. There were 34,989 women in the study with a median follow-up of 2.57 years (IQR 1.66 to 1.54 years) with a median time from diagnosis to delivery of three days (IQR 0 to 14 days). An increasing time from diagnosis to delivery was associated with an increased risk of an acute cardiovascular event (adjusted HR 1.06, 95% CI 1.01, 1.11 per week), in models adjusted for maternal comorbidities...Continue Reading

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.
