BET bromodomains mediate transcriptional pause release in heart failure.

Heart failure (HF) is driven by the interplay between regulatory transcription factors and dynamic alterations in chromatin structure. Pathologic gene transactivation in HF is associated with recruitment of histone acetyl-transferases and local chromatin hyperacetylation. We therefore assessed the role of acetyl-lysine reader proteins, or bromodomains, in HF.

The combination of EPA+DHA and low-dose aspirin ingestion reduces platelet function acutely whereas each alone may not in healthy humans.

Introduction: Aspirin's effectiveness in reducing cardiovascular disease events is inadequate in some individuals, a phenomenon termed aspirin "resistance". The hypothesis that combining low dose aspirin with eicosapentaenoic acid and docosahexaenoic acid (EPA+DHA) reduces platelet function in the acute setting has not been investigated.

Patients And Methods: We conducted a clinical trial of EPA+DHA and aspirin ingestion in healthy adults.

Review of ambulatory pulmonary artery catheterization in the management of advanced heart failure.

The use of pulmonary artery catheterization (PAC) has declined secondary to associated complications and lack of demonstrable efficacy in the inpatient setting. Few studies have been published on the use of PAC in nonacute heart failure (HF) patients. The purpose of this study was to review the use of PAC in guiding advanced therapy in nonacute ambulatory HF patients.

Novel therapeutic targets for preserving a healthy endothelium: strategies for reducing the risk of vascular and cardiovascular disease.

The endothelium lies in a strategic anatomical position between the circulating blood and the vascular smooth-muscle cells. It is a source of vasodilators such as nitric oxide, prostacyclin, and hyperpolarizing factor as well as heparin-like substances and other molecules with antiproliferative properties. These effects of endothelial cells may explain why platelets and monocytes usually do not adhere at the blood vessel wall.
