NCT01471795
Infections often occur after ventricular assist devices (VADs) are placed. These infections can be very serious. The goal of this study is to understand why these infections occur. Bacteria (germs) normally live on our skin and in our noses. After surgery, they can infect the VAD. The investigators will collect cultures of your skin and nose before and after surgery. The investigators will compare these bacteria to bacteria that cause infections. Their genes will be compared to see which ones help the bacteria cause infection.
NCT00971386
Heart failure is associated with faster breathing, which has a negative impact on the functioning of the heart. This leads to fatigue, shortness of breath, and exercise intolerance. It has been shown that when slow breathing technique was taught to patients with heart failure, they had a reduction in their sensation of shortness of breath and an improvement in their exercise performance. The study will compare the short-term effects of controlled slow breathing with biofeedback in normal healthy subjects, acute heart failure, and chronic stable heart failure. The purpose is to see if there is any change in the objective measurements of heart function while breathing at normal rates compared to a controlled slower rate.
