Neurohumoral activation in heart failure and the implications for treatment

Legate Philip, Paul R Kalra

Abstract

Introduction An acute pathological insult to the heart leads to a reduction in cardiac output (i.e. any cause of left ventricular systolic dysfunction [LVSD]), which activates a series of innate protective mechanisms. In the short term, activation of neurohumoral systems aim to preserve central arterial pressure and thereby vital organ perfusion, and include the sympathetic nervous system (SNS) and the renin–angiotensin–aldosterone system (RAAS). The net main effects of this process are: i) vasoconstriction; ii) sodium and water retention by the kidneys. While in the acute setting these adaptive responses may be beneficial, long-term over

News from the 7th Annual Scientific Meeting of the Cardiorenal Forum

Abstract

Introduction As doctors and scientists we are accustomed to breaking down problems and simplifying complex pathology in order to focus our management and identify possible targets for future therapies. The pathophysiology of cardiorenal disease is no different but, as yet, attempts to elucidate the complex interaction between heart and kidneys has failed. Although cardiac and renal disease are often diagnosed together, it is clear that a straightforward causal relationship does not exist. Disease in either serves as a risk factor for disease in the other and perpetuates the progression of that disease, but why this is so is unclear. Whilst th
