title: Sympathetic drive stimulating diastolic dysfunction?
abstract: Diastolic heart failure accounts for half of the heart failure population and its pathophysiology remains an area of active research. The renin angiotensin and aldosterone axis has been the focus of clinical trials to treat patients with heart failure with preserved ejection fraction, however with limited yield in terms of clinical success. Sympathetic activity has been considered a plausible cause for the molecular changes that lead to diastolic dysfunction. Based on this understanding the study by Gimelli et al uses MIBG to evaluate for association between diastolic dysfunction and sympathetic denervation. The results of this study set the stage for a follow up study for evaluation of sympathetic denervation in isolated diastolic dysfunction.
