A fast heart rate or an irregular ventricular rhythm can produce various degrees of functional impairment and structural remodeling of the ventricle referred to as tachycardiarelated cardiomyopathy or tachycardiomyopathy. This form of myocardial dysfunction can be caused by supraventricular or ventricular tachyarrhythmias that are incessant and associated with ventricular rates higher than 120 bpm. It can be reversed with pharmacological or nonpharmacological rate control or arrhythmia reversion. The prevalence of ventricular and supraventricular tachyarrhythmias is high among patients with heart failure. Consequently, in clinical settings, it may be difficult to determine whether a patient with severe ventricular dysfunction and supraventricular tachyarrhythmia associated with a rapid ventricular response is suffering from tachycardiomyopathy or from heart failure complicated by the subsequent development of a supraventricular tachyarrhythmia (e.g. atrial fibrillation). This typical ‘‘chicken-or-the-egg’’ dilemma can be resolved by treating the arrhythmia (pharmacological or nonpharmacological rate and/or rhythm control) and closely monitoring the evolution of the left ventricular dysfunction. Proper management of tachycardiomyopathy requires appropriate decision making, use of both pharmacological and nonpharmacological treatment approaches, and close follow-up. The purpose of this review article is to examine currently available data (experimental and clinical) on this complex clinical entity and on rate-control therapy.

Abstract Heart failure is nowadays a common condition associated with high mortality and increased healthcare-related costs. Over the years, the research on heart failure management has been extensive in order to better diagnose and treat the condition. Since the progression of left ventricular dysfunction is a consequence of myocardial inflammation, apopotosis, and fibrosis leading to myocardium remodelling, several molecules that are involved in the inflammation pathways have been explored as possible biomarkers for the condition. The study of biomarkers and their key roles in inflammation could allow early identification of patients with heart failure, improve prognostic assessment, and provide a target for future therapies. Among currently studied biomarkers, extensive research has been conducted on galectin-3, a galactoside-binding lectin, which is synthetised and secreted when cardiomyocytes and fibroblasts are submitted to mechanical stress. Accordingly, it has been hypothesised that galectin-3 could be a promoter of left ventricular dysfunction. Galectin-3 has been shown to mediate inflammation by several different pathways which are further detailed in the current review. Also, we aimed to provide a comprehensive overview of existing evidence on the utility of galectin-3 in clinical settings associated with heart failure.

We describe the case of an 86-year-old man with a background of severe left ventricular dysfunction and ischaemic cardiomyopathy who, having been optimised for heart failure therapy in hospital, unexpectedly deteriorated again with hypotension and progressive renal failure over the course of 2 days. Common causes of decompensation were ruled out and a bedside echocardiogram unexpectedly diagnosed new pericardial effusion with tamponade physiology. The patient underwent urgent pericardiocentesis and 890 mL of haemorrhagic fluid was drained. Common causes for haemopericardium were ruled out, and the spontaneous haemopericardium was thought to be related to introduction of rivaroxaban anticoagulation. The patient made a full recovery and was well 2 months following discharge. This case highlights the challenges of diagnosing cardiac tamponade in the presence of more common disorders that share similar non-specific clinical features. In addition, this case adds to growing evidence that therapy with direct oral anticoagulants can be complicated by spontaneous haemopericardium, especially when coadministered with other agents that affect clotting, renal dysfunction and cytochrome P3A5 inhibitors.
