The Year in Cardiology 2013: heart failure

Heart failure has become a worldwide epidemic of the 21st century with increasing impact on healthcare systems. The 2012 ESC and 2013 ACCF/AHA guidelines have set the stage for current therapy to reduce mortality and morbidity. There is a dawn of hope for therapy of acute and diastolic heart failure; it has become clearer that patients benefit from mitral reconstruction and which patients benefit from heart failure management programmes; genetics and proteomics advance in great strides; competing concepts of cell therapy seem to spiral, hopefully upwards; and we can further nurture our hope for evidence-based individualized diagnostic and therap

The year in cardiology: heart failure 2014

The year 2014 has become a remarkable year for heart failure. A bad start was caused by the publication of TOPCAT, showing that spironolactone did not prove to be beneficial for the treatment of patients with heart failure and preserved ejection fraction (HFpEF). Nevertheless, further insights in the study yields a few bright spots, and treatment with spironolactone might still be considered in patients with HFpEF. In acute heart failure, additional data were published on the effects of serelaxin. Serelaxin reduced wedge pressures, had similar effects in acute heart failure patients with and without a reduced ejection fraction, and had a neutral effect on diuretic response. But the most important news was related to the results of PARADIGM, where LCZ696, the first-in-class angiotensin-receptor neprilysin inhibitor, proved to be superior to enalapril in reducing mortality and morbidity in patients with heart failure and reduced ejection fraction (HFrEF

Darusentan, a selective endothelin A receptor antagonist, for the oral treatment of resistant hypertension

Resistant hypertension is defined as failure to lower blood pressure to target when a patient adheres to the maximum tolerated doses of three antihypertensive drugs including a diuretic. Notwithstanding the wide availability of several antihypertensive agents and the continued recommendation of dietary and lifestyle modifications, the prevalence of resistant hypertension remains high and is expected to increase thus underscoring the need for potential new treatment modalities in resistant hypertension. Endothelin-1 is a long-lasting potent vasoconstrictor and plays a key role in cardiovascular haemostasis. Endothelin mediates its biological activity in humans through the endothelin A and B receptors. The clinical experience and the evidence for therapy with darusentan in resistant systemic hypertension are reviewed. The leading journals that publish basic science and clinical research in the area of cardiovascular diseases and PubMed were scanned. While results from early clinical studies suggested that darusentan might emerge as new treatment option in patients with resistant hypertension, results from recent studies suggests that darusentan appears unlikely to find its way in the armamentarium for treatment of resistant hypertension
