Topoisomerase 2B Decrease Results in Diastolic Dysfunction via p53 and Akt: A Novel Pathway

open access: yesFrontiers in Cardiovascular Medicine, 2020
Diastolic dysfunction is condition of a stiff ventricle and a function of aging. It causes significant cardiovascular mortality and morbidity, and in fact, three million Americans are currently suffering from this condition.

Piezo1 Upregulation in Monocyte‐Derived Macrophages Impairs Post‐Myocardial Infarction Cardiac Repair via Defective Efferocytosis and Enhanced Ferroptosis

open access: yesAdvanced Science, EarlyView.
This study reports early Piezo1 activation in bone marrow monocyte‐derived macrophages (MoMs) during myocardial infarction (MI), which governs the fate and function of recruited macrophages. The recruited MoMs with increased Piezo1 expression exhibit increased ferroptosis and defective efferocytosis, delayed clearance of dead cells and resolution of ...

Myocardial Performance Index (Tei Index): A simple tool to identify cardiac dysfunction in patients with diabetes mellitus

open access: yesIndian Heart Journal, 2016
Background: Cardiac dysfunction is the major cause of morbidity and mortality in diabetes. Myocardial Performance Index (MPI/Tei Index) includes both systolic and diastolic time intervals to assess the global cardiac dysfunction.

What every ICU clinician needs to know about the cardiovascular effects caused by abdominal hypertension [PDF]

open access: yes, 2015
The effects of increased intra-abdominal pressure (IAP) on cardiovascular function are well recognized and include a combined negative effect on preload, afterload and contractility.

Promoting Autophagy Mitigates Stress‐Induced Remodeling in Patient iPSC‐CMs with the Phospholamban R9C Mutation

open access: yesAdvanced Science, EarlyView.
The Phospholamban (PLN) R9C mutation reduces SERCA2a binding, increasing calcium recycling and baseline contractility. However, the excess of free PLN promotes pentamer formation, limiting phosphorylation and blunting β‐adrenergic signaling. Under cardiac stress, enhanced functional demands overwhelm proteostasis in PLN R9C cells, leading to misfolded ...

Engineered Multifunctional Hydrogel Delivering Novel CBX7 Inhibitor Modulates Cuproptosis Via Liquid–Liquid Phase Separation to Restore Cardiac Function in Aged Myocardial Infarction

open access: yesAdvanced Science, EarlyView.
An age‐adapted therapy pairs δ‐Amyrenone, a CBX7 inhibitor, with an alginate hydrogel (CSAδ) to rescue infarcted elderly hearts. CSAδ disrupts CBX7–ATP7A liquid–liquid phase separation, restores ATP7A trafficking and copper efflux, suppresses cuproptosis, supplies oxygen, scavenges ROS, promotes M2 polarization, supports angiogenesis, and enhances ...

Novel pathways of heart failure with preserved ejection fraction [PDF]

open access: yes, 2016
INTRODUCTION: Diastolic heart failure (HF) i.e., HF with preserved ejection fraction (HFpEF) accounts for ~50% of all clinical HF presentations; but unlike systolic HF i.e., HF with reduced ejection fraction (HFrEF), there are no evidenced based ...

TLR4 and NLRP3 Caspase 1- IL-1β- Axis are not Involved in Colon Ascendens Stent Peritonitis (Casp)-Associated Heart Disease [PDF]

open access: yes, 2018
Hemodynamic collapse and myocardial dysfunction are among the major causes ofdeath in severe sepsis. The purpose of this study was to assess the role played by TLR4and by the NLRP3 inflammasome in the cardiac dysfunction that occurs after ...
