Interpretation of the central aortic pressure waveform in elderly patients with aortic stenosis.

Am J Physiol Heart Circ Physiol

June 2023

The CardioVascular Center, Tufts Medical Center, Boston, Massachusetts, United States.

The central aortic pressure waveform, while simple in form, is complex in its physiological interpretation. Although general agreement has been reached on the contour and mechanisms responsible for pressure waveforms in the ascending aorta of healthy humans, in recent years there has been increasing interest in the contour of the pressure wave in elderly patients with aortic valve stenosis (AS). As aortic valve leaflets succumb to fibrosis and calcification, they increase opposition to forward flow.

Article Synopsis
  • Mobile health apps are becoming popular, but few have utilized tablet-based technology in managing heart failure (HF) effectively.
  • A study compared a traditional telephone-based HF management program to one that included remote monitoring via a tablet, tracking various health metrics over 90 days.
  • The results showed no significant difference in hospitalization days between the two approaches, suggesting that adding tablet monitoring may not be beneficial, though the study's limitations could affect the findings.

Arrhythmogenic cardiomyopathy (ACM), a fatal heart disease characterized by fibroadipocytic replacement of cardiac myocytes, accounts for 20% of sudden cardiac death and lacks effective treatment. It is often caused by mutations in desmosome proteins, with Desmoglein-2 (DSG2) mutations as a common etiology. However, the mechanism underlying the accumulation of fibrofatty in ACM remains unknown, which impedes the development of curative treatment.

Transcatheter aortic valve replacement (TAVR) has become the preferred treatment for severe aortic stenosis. Previous studies compare clinical outcomes of leading TAVR valves, but there is no evidence of cost-utility comparison, leaving a clinical information gap when selecting valves. Here we share a cost-utility analysis comparing the Sapien 3 (S3) (Edwards Lifesciences, Irvine, CA) and CoreValve Evolut R (ER) (Medtronic, Dublin, IR) across five clinical endpoints.

Background: Dysfunction of endothelial cells links to microvascular rarefaction, reflecting the pathogenesis of hypertension. Our previous studies found that miR-3656 reduces nitric oxide generation and von Willebrand factor (vWF) cleavage, thereby retarding blood flow and potentially increasing blood pressure. In this paper, we investigated mechanism of transcription regulation contributing to miR-3656-damaged endothelial cells in hypertension.

Heart failure with preserved ejection fraction (HFpEF) is a major driver of cardiac morbidity and mortality in developed countries, due to ageing populations and the increasing prevalence of comorbidities. While heart failure with reduced ejection fraction is dominated by left ventricular impairment, HFpEF results from a complex interplay of cardiac remodelling, peripheral circulation, and concomitant features including age, hypertension, obesity, and diabetes. In an important subset, however, HFpEF is subtended by specific diseases of the myocardium that are genetically determined, have distinct pathophysiology, and are increasingly amenable to targeted, innovative treatments.

Efforts to fully understand pharmacological differences between G protein-coupled receptor (GPCR) species homologues are generally not pursued in detail during the drug development process. To date, many GPCRs that have been successfully targeted are relatively well-conserved across species in amino acid sequence and display minimal variability of biological effects. However, the A adenosine receptor (AR), an exciting drug target for a multitude of diseases associated with tissue injury, ischemia, and inflammation, displays as little as 70% sequence identity among mammalian species (e.
