Heart failure is a complex clinical syndrome. Jamshid Easa, Jacob Chappell and David Warriner explain the pathogenesis behind the most common form of this condition Heart failure a complex clinical syndrome due to impairment of ventricular filling or contraction, resulting in a constellation of physical symptoms and signs, primarily due to salt and water retention. In this clinically focused review of the pathophysiology, we will summarise the main consequences of the most common type, left ventricular failure; knowledge of which is essential for those working in general practice due to the high prevalence of heart failure in the community and to aid understanding of the various pharmacotherapies that work to act on the pathological mechanisms.

Heart failure (HF) is a common clinical syndrome with ever-increasing prevalence in the Western world. It is associated with extensive morbidity and mortality, as well as being a significant burden on global healthcare systems. It is due to impairment of ventricular filling or contraction, resulting in a constellation of physical symptoms and signs, primarily due to salt and water retention. An understanding of the pharmacological options to manage the condition is imperative to quickly alleviate symptoms and avert a rapidly progressive downward spiral, improving not only quality but also quantity of life.

Abstract Background Temporal trends in clinical composition and outcome in dilated cardiomyopathy (DCM) are largely unknown, despite considerable advances in heart failure management. We set out to study clinical characteristics and prognosis over time in DCM in Sweden during 2003–2015. Methods DCM patients (n = 7873) from the Swedish Heart Failure Registry were divided into three calendar periods of inclusion, 2003–2007 (Period 1, n = 2029), 2008–2011 (Period 2, n = 3363), 2012–2015 (Period 3, n = 2481). The primary outcome was the composite of all-cause death, transplantation and hospitalization during 1 year after inclusion into the registry. Results Over the three calendar periods patients were older (p = 0.022), the proportion of females increased (mean 22.5%, 26.4%, 27.6%, p = 0.0001), left ventricular ejection fraction was higher (p = 0.0014), and symptoms by New York Heart Association less severe (p < 0.0001). Device (implantable cardioverter defibrillator and/or cardiac resynchronization) therapy increased by 30% over time (mean 11.6%, 12.3%, 15.1%, p < 0.0001). The event rates for mortality, and hospitalization were consistently decreasing over calendar periods (p < 0.0001 for all), whereas transplantation rate was stable. More advanced physical symptoms correlated with an increased risk of a composite outcome over time (p = 0.0043). Conclusions From 2003 until 2015, we observed declining mortality and hospitalizations in DCM, paralleled by a continuous change in both demographic profile and therapy in the DCM population in Sweden, towards a less affected phenotype.

Heart failure has been defined in many ways and definitions change over time. The multiplicity of definitions reflect the paucity of our understanding of the primary underlying physiology of heart failure and the many diseases for which heart failure is the common end-point. Fundamentally, heart failure represents a failure of the heart to meet the body’s requirement for blood supply for whatever reason. It is thus a clinical syndrome with characteristic features – not a single disease in its own right. The syndrome includes symptoms and signs of organ underperfusion, fluid retention and neuroendocrine activation. The syndrome arises from a range of possible causes of which ischaemic heart disease is the commonest. From the point of view of a clinician, the underlying pathology will determine treatment options and prognosis. The extensive range of possible aetiologies present a diagnostic challenge both to correctly identify the syndrome amongst all other causes of dyspnoea and to identify the aetiology, allowing optimization of treatment.
