(Submitter supplied) In order to better understand sex-related differences of heart failure with preserved ejection fraction (HFpEF), male and female kittens underwent aortic contriction surgery (banding) or sham surgery (normal). Slow progressive pressure overload was then compared between male and female kittens, analyzing structural and functional phenotypes. Transcriptional differences between male and female kittens were investigated via single nuclear RNA sequencing (snRNA-seq) within left ventricle tissue.

(Submitter supplied) Heart failure with preserved ejection fraction (HFpEF) is a clinical syndrome with multisystem organ dysfunction in which patients develop symptoms of HF as the result of high left ventricular (LV) diastolic pressure Continuous infusion of angiotensin II and phenylephrine (AngII/PE) demonstrates a strong HFpEF phenotype RNAseq data demonstrate activation of pathways leading to myocardial metabolic changes, activation of ECM deposition, microvascular rarefaction, and pressure and volume related myocardial stress

(Submitter supplied) C57Bl6/J female mice were ovariectomized or not at the age of 12 months and then euthanized 12 months later at the age of 24 months. Half of the females received for 28 days an angiotensin II (AngII; 1.5 mg/kg/day) continuous infusion starting at the age of 23 months. The mice were provided with a running wheel during the 12 months after gonadectomy with the exception of the last month before euthanasia.

(Submitter supplied) In order to study the capacity of the myocardium to recover from a stress causing several features of heart failure with preserved ejection fraction, C57Bl6/J male and female mice received or not for 28 days an angiotensin II (AngII; 1,5 mg/kg/day) continuous infusion in combination with a high fat diet (HFD). Half of the animals were then euthanized. The remaining ones had the AngII infusion stopped and their diet normalized. more...

(Submitter supplied) Background: Left ventricular pressure overload (LVPO) can lead to heart failure with a preserved ejection fraction (HFpEF), whereby increased LV chamber stiffness (LV Kc) is a hallmark. However, how post-transcriptional pathways, specifically microRNAs (miRs) may contribute to increased LV Kc and HFpEF progression remains unclear. This project tested the central hypothesis that the development of HFpEF secondary to a prolonged LVPO stimulus, will result in a shift in miRs that will be related to LV Kc. more...

(Submitter supplied) To understand the cellular mechanisms of heart failure with preserved ejection fraction (HFpEF), We investigated the functional outcome and the underlying mechanisms from concurrent mechanic and metabolic stresses in the heart by applying transverse aortic constriction (TAC) in lean C57Bl/6J (HFrEF phenotype) or obese/diabetic B6.Cg-Lepob/J (ob/ob) mice (HFpEF phenotype) followed by single-nuclei RNA-seq (snRNA-seq) and targeted manipulation of a top ranked signaling pathway (glucagon receptor signaling) differentially affected in the two experimental cohorts.
