A Systems Approach - Human Cardiac Electromechanical Activity

The challenge is to identify limitations in using data from non-human animal species for elucidation of human electromechanical function/activity and to identify what specific information and computational approaches need to be incorporated. To aid in achieving such a goal, it might be useful to convene a series of workshops to build consensus and improve communication among investigators working at the same horizontal ...more »

How can we non-invasively, but still accurately, measure blood pressure in the pulmonary arteries?

Pulmonary hypertension (PH) is a complex, progressive condition characterized by high blood pressure in the lungs. The gold standard for measuring pressures in the pulmonary arteries is a right heart catheterization, where a special catheter is guided through the right side of the heart and into the pulmonary artery, the main vessel carrying blood to the lungs. This measurement is essential, as it allows physicians and ...more »

Embedding the future of regenerative medicine into the open epigenomic landscape of pluripotent human embryonic stem cells

Large-scale profiling of developmental regulators and histone modifications by genome-wide approaches have provided powerful genome-wide, high-throughput, and high resolution techniques that lead to great advances in our understanding of the global phenomena of human developmental processes. However, without a practical strategy to convert pluripotent cells direct into a specific lineage, previous studies are limited ...more »

Improving understanding of heart attack mechanisms in women and targeting of treatment

There remain many differences between women and men in the risk of myocardial infarction (MI or “heart attack”), manifestations of MI and outcomes after MI. The time in which the facts about differences between the sexes were unknown or ignored has passed. However, there are many basic answers women and their physicians need, such as: a) Why are younger women with MI at such high risk of death as compared to their male ...more »

Critical Challenge

• One of the most important public health issues the Nation faces is the rising incidence of heart failure. HF incidence rates have risen faster than predicted. The prevalence will increase as better and more therapy becomes available. While heart failure is the biggest ticket item in the Medicare budget, the cost to society will increase more than it has already. But much HF can be prevented or onset prolonged. Investing ...more »

Treatment of Major Depression in Patients with Heart Failure

Major depression (MD) is common in patients with heart failure, and it is an independent risk marker for functional decline, hospitalization, and mortality. Two large trials have shown that it can be difficult to treat. SADHART-CHF, a double-blind, placebo-controlled RCT (n=469), found that sertraline was not efficacious for MD in HF. MOOD-HF (n=372) showed that escitalopram was not efficacious. Smaller trials of cognitive-behavioral ...more »

The role of Extracorporeal Photopheresis (ECP) in the prevention and treatment of rejection of heart and lung transplants

According to the ISHLT, more than 4,000 patients undergo a heart transplant each year, and almost 4,000 receive single or double lung transplants. Their prognosis depends heavily on the avoidance of rejection, which claims the majority of their lives. For heart transplant recipients, the median survival is 11 years, while for lung transplant recipients, it is approximately 5 years. The current most common anti-rejection ...more »

Modulation of cardiac contraction and relaxation in heart failure: role of systemic inflammation

Is cardiac contraction and relaxation in heart failure modulated by the systemic inflammatory response? There is overwhelming evidence that inflammatory biomarkers predict worse outcome in acute and chronic heart failure. Despite the wealth of evidence, clinical trials in this area have either not been completed, failed, or provided inconclusive results. The questions that remain are: 1) Is inflammation a mechanism ...more »
