BACKGROUND Continuous-flow (CF) pumps have yielded improvements in short- and long-term survival and quality of life, and have reduced the number of left ventricular assist device (LVAD)-related complications. However, their ability to unload the right ventricle (RV) and improve RV function has not been as clearly defined. We evaluated the short- and(More)
BACKGROUND Worsening renal function (WRF) during heart failure (HF) hospitalization is an accepted correlate of poor prognosis. Loop diuretics are increasingly being considered as a potential cause of worsened HF outcomes, perhaps via WRF. However, the magnitude of worsening in renal function attributable to loop diuretics has not been quantified. METHODS(More)
BACKGROUND Continuous flow left ventricular assist devices (CF-LVADs) have yielded improved outcomes compared with pulsatile flow devices for patients on long-term support. However, significant rates of gastrointestinal bleeding (GIB) have been observed during CF-LVAD support. METHODS From March 2006 through March 2011, 86 patients with chronic heart(More)
BACKGROUND Adherence to inhaled corticosteroids (ICSs) is known to be poor among patients with asthma; however, little is known about patients who do not fill their ICS prescriptions (ie, primary nonadherence). OBJECTIVE To estimate rates of primary nonadherence and to explore associated factors. METHODS The study population was members of a large(More)
Pharmacogenetics is a growing field of research that focuses on the interaction between genetics and drug therapy. Relationships between genetic variation and drug effect have been observed for a growing number of commonly used drugs. Validation studies may soon define the use of these relationships in clinical practice, moving the field toward routine(More)
OBJECTIVES Overcoming racial differences in acute coronary syndrome (ACS) outcomes is a strategic goal for U.S. health care. Genetic polymorphisms in the adrenergic pathway seem to explain some outcome differences by race in other cardiovascular diseases treated with β-adrenergic receptor blockade (BB). Whether these genetic variants are associated with(More)
The individual patient responses to chronic heart failure (HF) pharmacotherapies are highly variable. This variability cannot be entirely explained by clinical characteristics, and genetic variation may play a role. Therefore, this review will summarize the background pharmacogenetic literature for major HF pharmacotherapy classes (ie, β-blockers,(More)
Most current methods for modeling rehospitalization events in heart failure patients make use of only clinical and medications data that is available in the electronic health records. However, information about patient-reported functional limitations, behavioral variables and socio-economic background of patients may also play an important role in(More)
OBJECTIVES This study examined the effects of a cardiac rehabilitation (CR) program on functional capacity and health status (HS) in patients with newly implanted left ventricular assist devices (LVADs). BACKGROUND Reduced functional capacity and HS are independent predictors of mortality in patients with heart failure. CR improves both, and is related to(More)
