As a result of the aging Canadian population and improved heart failure management, more than 400,000 Canadians are currently living with heart failure. Despite recent advances in medical management, no cure exists and the annual mortality rate for heart failure remains as high as 40%. Research suggests that end-stage heart failure patients suffer to a degree that is equivalent to, or greater than that of terminal cancer patients. However, they do not receive the same degree of end-of-life care. This article discusses current issues related to the classification system, the lack of prognostic markers, and medical management of the end-stage heart failure patient, which act as barriers to implementing palliative care. Possible solutions to facilitate the effective and timely transition to palliative care, and achieve the goal of a peaceful death for the patient with end-stage heart failure are also discussed.

Introduction: The cardiotoxicity and subsequent Heart Failure (HF) induced by Doxorubicin (DOX) limit the clinical application of DOX. Valsartan (Val) is an angiotensin II receptor blocker that could attenuate the HF induced by DOX. However, the underlying mechanism of Val in this process is not fully understood.

Background: Adrenomedullin 2 (AM2) plays critical roles in regulating blood pressure and fluid balance. However, the specific involvement of AM2 in cardiac hypertrophy has not been comprehensively elucidated, warranting further investigation into its molecular mechanisms and therapeutic implications.
Methods: Cardiac hypertrophy was induced in adult mice lacking AM2 (AM2-/-) using transverse aortic constriction surgery.

Background: Increased burden of socially determined vulnerabilities (SDV), which include nonmedical conditions that contribute to patient health, is associated with incident heart failure (HF). Mediators of this association have not been examined. We aimed to determine if a healthy lifestyle mediates the association between SDV and HF.

Ostium secondum ASD accounts for a large proportion of these defects and often goes unnoticed during childhood and adolescence. Pulmonary hypertension (PH), affecting a significant number of patients with ostium secondum ASD, is associated with functional limitations, heart failure, and tachyarrhythmias.

Diabetes mellitus (DM) is a debilitating disorder that impacts all systems of the body and has been increasing in prevalence throughout the globe. DM represents a significant clinical challenge to care for individuals and prevent the onset of chronic disability and ultimately death. Underlying cellular mechanisms for the onset and development of DM are multi-factorial in origin and involve pathways associated with the production of reactive oxygen species and the generation of oxidative stress as well as the dysfunction of mitochondrial cellular organelles, programmed cell death, and circadian rhythm impairments.
