Heart failure is a chronic, progressive illness that is increasing in prevalence in the USA. Patients with advanced heart failure experience a high symptom burden that is comparable to patients with advanced cancer. Palliative care, however, is underutilized in patients with heart failure, and symptoms may go untreated as the disease progresses. A combination of pharmacologic and non-pharmacologic interventions should be used to address symptoms and maintain quality of life. While there have been significant advances in evidence-based heart failure treatments in recent years, selection of appropriate palliative medications as symptoms progress is challenging due to limited clinical studies in this patient population...

Despite the recent advances in the management of heart failure, the mortality of heart failure patients remains high. It is of urgent need to develop new therapy for heart failure. Heart failure is characterized by increased sympathetic activity, and chronic sympathetic activation is involved in the maintenance of the pathological state. Catheter-based renal denervation (RDN) has emerged as an invasive but safe approach that can reduce sympathetic activation. Studies have reported inconsistent results regarding the effect of RDN in heart failure patients due to limited power with small sample sizes...

BACKGROUND: We previously reported that the long-acting loop diuretic azosemide improves cardiac sympathetic nerve activity (CSNA) in patients with chronic heart failure (CHF), compared with short-acting furosemide. However, its influence on mortality has not been determined. METHODS: The present study was a further analysis of our previously published study in which azosemide showed improved (123)I-metaiodobenzylguanidine scintigraphic findings compared with furosemide in CHF patients with reduced left ventricular ejection fraction (LVEF)...

BACKGROUND: Heart failure (HF) is associated with chronic sympathetic activation. Renal denervation (RDN) aims to reduce sympathetic activity by ablating the renal sympathetic nerves. We investigated the effect of RDN in patients with chronic HF and concurrent renal dysfunction, in a prospective, multicenter, single-arm feasibility study. METHODS AND RESULTS: Thirty-nine patients with chronic systolic HF (left ventricular ejection fraction [LVEF] <40%, New York Heart Association class II-III,) and renal impairment (estimated glomerular filtration rate [eGFR; assessed with Modification of Diet in Renal Disease equation] <75 mL/min/1...

Transient receptor potential (TRP) channels constitute a large family of versatile multi-signal transducers. In particular, TRP canonical (TRPC) channels are known as receptor-operated, non-selective cation channels. TRPC3 and TRPC6, two members in the TRPC family, are highly expressed in the heart, and participate in the pathogenesis of cardiac hypertrophy and heart failure as a pathological response to chronic mechanical stress. In the pathological response, myocardial stretch increases intracellular Ca(2+) levels and activates nuclear factor of activated T cells to induce cardiac hypertrophy...

PURPOSE: Cardiovascular (CV) diseases in type 2 diabetes (T2DM) represent an enormous burden with high mortality and morbidity. Sodium-glucose cotransporter 2 (SGLT2) inhibitors have recently emerged as a new antidiabetic class that improves glucose control, as well as body weight and blood pressure with no increased risk of hypoglycemia. The first CV outcome study terminated with empagliflozin, a specific SGLT2 inhibitor, has shown a reduction in CV mortality and in heart failure hospitalization, suggesting a beneficial impact on cardiac function which remains to be demonstrated...

OBJECTIVE: Cardiac hexokinase II (HKII) can translocate between cytosol and mitochondria and change its cellular expression with pathologies such as ischemia-reperfusion, diabetes and heart failure. The cardiac metabolic consequences of these changes are unknown. Here we measured energy substrate utilization in cytosol and mitochondria using stabile isotopes and oxygen consumption of the intact perfused heart for 1) an acute decrease in mitochondrial HKII (mtHKII), and 2) a chronic decrease in total cellular HKII...

Atrial fibrillation is the most common cardiac arrhythmia in adults affecting almost 6 million adults in the United States. The 2 most common comorbidities associated with atrial fibrillation are heart failure and thromboembolic events. Heart failure symptoms may be treated with rate control, antiarrhythmic medications or by catheter ablation. Unfortunately, despite optimal medical management, thromboembolic events still occur. Recently, there has been a great deal of interest and innovation in finding an alternative to chronic anticoagulation...

BACKGROUND: Transitions in care can increase patients' vulnerability to adverse events. In particular, patients admitted for heart failure or chronic obstructive pulmonary disorder (COPD) have high rates of readmission and return emergency department visits. Heart failure patients have the highest 30-day readmission rates in Canada, and COPD patients comprise the highest volume of readmissions. Combined, these two conditions account for the largest number of emergency department returns...

Stress-induced p38 mitogen-activated protein kinase (MAPK) activity is implicated in pathological remodeling in the heart. For example, constitutive p38 MAPK activation in cardiomyocytes induces pathological features, including myocyte hypertrophy, apoptosis, contractile dysfunction, and fetal gene expression. However, the physiological function of cardiomyocyte p38 MAPK activity in beneficial compensatory vascular remodeling is unclear. This report investigated the functional role and the underlying mechanisms of cardiomyocyte p38 MAPK activity in cardiac remodeling induced by chronic stress...
