Association of Race and Ethnicity and Social Factors With Postpartum Primary Care or Cardiology Follow-Up Visits Among Individuals With Preeclampsia.

Background: Preeclampsia is associated with increased cardiovascular morbidity and death. Primary care or cardiology follow-up, in complement to routine postpartum obstetric care, provides an essential opportunity to address cardiovascular risk. Prior studies investigating racial differences in the recommended postpartum follow-up have incompletely assessed the influence of social factors.

Postpartum Weight Change Association With Readmission and Blood Pressure Trend Among Individuals With Hypertensive Disorders of Pregnancy.

Background: The aim of this study was to evaluate the association between early postpartum weight change and (1) hospital readmission and (2) 2-week blood pressure trajectory.

Methods And Results: This retrospective study cohort included 1365 individuals with a hypertensive disorder of pregnancy enrolled in a postpartum hypertension remote monitoring program. Exposure was percentage weight change from delivery to first weight recorded within 10 days postpartum.

Immune Markers, Blood Pressure Severity, and Cardiac Remodeling 1 to 2 Years After Hypertensive Disorders of Pregnancy.

Background Cardiovascular dysfunction and hypertension can persist postpartum following hypertensive disorders of pregnancy (HDPs). This study hypothesized that activin A, proinflammatory markers and concentric remodeling by echo would be higher 1-2 years postpartum following HDP with persistent hypertension compared to HDP with normalized blood pressure (BP). We further hypothesized correlations between biomarkers with BP and echocardiographic indices.

Single Nucleotide Polymorphism rs9277336 Controls the Nuclear Alpha Actinin 4-Human Leukocyte Antigen-DPA1 Axis and Pulmonary Endothelial Pathophenotypes in Pulmonary Arterial Hypertension.

Background Pulmonary arterial hypertension (PAH) is a complex, fatal disease where disease severity has been associated with the single nucleotide polymorphism (SNP) rs2856830, located near the human leukocyte antigen DPA1 (HLA-DPA1) gene. We aimed to define the genetic architecture of functional variants associated with PAH disease severity by identifying allele-specific binding transcription factors and downstream targets that control endothelial pathophenotypes and PAH. Methods and Results Electrophoretic mobility shift assays of oligonucleotides containing SNP rs2856830 and 8 SNPs in linkage disequilibrium revealed functional SNPs via allele-imbalanced binding to human pulmonary arterial endothelial cell nuclear proteins.

Association Between Copayment and Adherence to Medications for Pulmonary Arterial Hypertension.

Background Pharmacologic treatment for pulmonary arterial hypertension (PAH) improves exercise capacity, functional class, and hemodynamic indexes. However, monthly prescription costs often exceed $4000. We examined associations between (1) medication copayment and (2) annual household income with adherence to pulmonary vasodilator therapy among individuals with PAH.

Tissue Sodium in Patients With Early Stage Hypertension: A Randomized Controlled Trial.

Background Sodium (Na) stored in skin and muscle tissue is associated with essential hypertension. Sodium magnetic resonance imaging is a validated method of quantifying tissue stores of Na. In this study, we evaluated tissue Na in patients with elevated blood pressure or stage I hypertension in response to diuretic therapy or low Na diet.

Impact of an Automated Best Practice Alert on Sex and Race Disparities in Implantable Cardioverter-Defibrillator Therapy.

Background Implantable cardioverter-defibrillators (ICDs) are indicated in patients with severe left ventricular dysfunction, but many eligible patients do not receive them, especially women and Black patients. Our group had previously demonstrated that a best practice alert (BPA) improves overall rates of electrophysiology referrals and ICD implantations. This study examined the impact of a BPA by sex and race.
