Despite the increasing prevalence and substantial burden of heart failure with preserved ejection fraction (HFpEF), which constitutes up to 50% of all heart failure cases, significant challenges persist in its diagnostic and therapeutic strategies. These difficulties arise primarily from the heterogeneous nature of the condition, the presence of various comorbidities and a wide range of phenotypic variations. Considering these challenges, current international guidelines endorse the utilization of invasive haemodynamic assessments, including resting and exercise haemodynamics, as the gold standard for enhancing diagnostic accuracy in cases where traditional diagnostic methods yield inconclusive results. These assessments are crucial not only for confirming the diagnosis but also for delineating the complex underlying pathophysiology, enabling the development of personalized treatment strategies, and facilitating the precise classification of HFpEF phenotypes. In this review, we summarize the haemodynamic changes observed in patients with HFpEF, comparing resting and exercise-induced parameters to those of normal subjects. Additionally, we discuss the current role of invasive haemodynamics in HFpEF assessment and highlight its utility beyond diagnosis, such as identifying HFpEF comorbidities, guiding phenotype-based personalized therapies and characterizing prognostication. Finally, we address the challenges associated with utilizing invasive haemodynamics and propose future directions, focusing on integrating these assessments into routine HFpEF care.

Patients with congenitally corrected transposition of the great arteries (ccTGA) can be treated with a double switch operation (DSO) to restore the normal anatomical connection of the left ventricle (LV) to the systemic circulation and the right ventricle (RV) to the pulmonary circulation. The subpulmonary LV progressively deconditions over time due to its connection to the low pressure pulmonary circulation and needs to be retrained using a surgical pulmonary artery band (PAB) for 6-12 months prior to the DSO. The subsequent clinical follow-up, consisting of invasive cardiac pressure and non-invasive imaging data, evaluates LV preparedness for the DSO.

Semaglutide protects against diabetes-associated cardiac inflammation via Sirt3-dependent RKIP pathway.

Br J Pharmacol

Department of Cardiology, Shanghai Institute of Cardiovascular Diseases, Zhongshan Hospital, Fudan University, Shanghai, China.

Background And Purpose: Glucagon-like peptide-1 receptor agonists (GLP-1RAs) exert cardiovascular benefits in diabetic patients, but the underlying mechanisms remain incompletely understood. Semaglutide, a novel long-acting GLP-1RA, has shown a reduced risk of cardiovascular events. Based on these results, we investigated the therapeutic potential of semaglutide in diabetic cardiomyopathy and sought to elucidate the underlying mechanisms.

Introduction: Thyroid storm or severe hyperthyroidism can present with various signs and symptoms. They are mostly controlled by general treatment, such as anti-thyroid drugs and other medications to control clinical features. However, in rare cases, they are more severe, and they only respond to more aggressive treatments, such as plasmapheresis and total thyroidectomy.

The outcomes of bifurcation percutaneous coronary intervention (PCI) in octogenarians and nonagenarians have received limited study. We compared the procedural characteristics and outcomes of bifurcation PCIs among patients ≥80 vs <80-years-old in a multicenter registry. Of 1,253 patients who underwent 1,262 bifurcation PCIs between 2014 and 2024 at six centers, 194 (15%) were octogenarians or nonagenarians.

Trends in heart failure-related mortality among middle-aged adults in the United States from 1999-2022.

Curr Probl Cardiol

Department of Medicine, Creighton University School of Medicine, 7710 Mercy Road, Suite 301, Omaha, Nebraska, United States of America 68124.

Introduction: Heart failure (HF) represents a significant contributor to morbidity and mortality. Heart failure mortality trends among the middle aged have not been fully characterized into the years of the COVID-19 pandemic. Our objective was to analyze the trends in mortality related to heart failure across various demographic and geographic categories-including gender, race, and census region-spanning from 1999 to 2022, with particular attention paid to the effect of the COVID-19 pandemic on HF mortality.
