Heart failure is a major public health problem. Heart failure with preserved systolic function (HF-PSF) is a common form, which is difficult to diagnose. Results of recent studies show that HF-PSF has a poor prognosis, with an annual survival rate similar to that of heart failure with left ventricular systolic dysfunction. Despite these findings, the therapeutic management of HF-PSF is not clea...

BACKGROUND Hospitals enrolled in the American Heart Association's Get With The Guidelines Program for heart failure (GWTG-HF) have improved their process of care. However, it is unclear if process of care and outcomes are better in the GWTG-HF hospitals compared with hospitals not enrolled. METHODS AND RESULTS We compared hospitals enrolled in GWTG-HF from 2006 to 2007 with other hospitals us...

Heart failure (HF) is a major health burden in worldwide. As the end point of numerous cardiovascular diseases, HF is the main cause of disability and death, and its five-year mortality is even higher than that of malignant tumor. The etiologies of heart failure are various, foremost among them is cardiac hypertrophy and myocardial ischemia. We have been committing to research the mechanisms of...

Heart Failure With Preserved Ejection Fraction Heart failure with preserved ejection fraction (HFpEF) or diastolic heart failure (HF) accounts for approximately half of HF cases in the community, and the portion of HF with preserved ejection fraction (EF) is increasing. Patients with HFpEF have limited functional capacity and poor prognosis. With ongoing shifts in the age distribution of the po...

Atrial fibrillation (AF) and heart failure (HF) are common conditions that frequently coexist. Both conditions share risk factors, are associated with increased morbidity and mortality, and may worsen the other. The presence of heart failure and symptoms associated with it may influence both the approach to management (i.e., rate versus rhythm control) and the treatment options available for AF...

Continued assessment of temporal trends in mortality and epidemiology of specific heart failure in South America is needed to provide a scientific basis for rational allocation of the limited health care resources, and strategies to reduce risk and predict the future burden of heart failure. The epidemiology of heart failure in South America was reviewed. Heart failure is the main cause of hosp...

This research investigated the predictive value of combined detection brain natriuretic peptide (BNP) and cystatin C (Cys C) in heart failure after percutaneous coronary intervention (PCI) patients with acute myocardial infarction (AMI). Sixty-five AMI complicated by (HF) PCI 79 non-heart (non-HF) were involved this research. The levels Cys BNP measured. Risk factors for analyzed multivariate l...

INTRODUCTION Despite striking improvement in the prognosis and survival in patients with coronary artery disease (CAD), hypertension, and congenital heart disease, the prevalence of heart failure (HF) is still growing. HF is the most common cause of hospitalization after normal delivery approximately 1 million patients are hospitalized annually for HF in the United States. Moreover, the prognos...

conclusions this study will be an important step in creating an evidence base for the relative benefits of different educational strategies for reducing readmissions. results patients correctly answered three out of four, or 75%, of self-care teach-back questions. in the intervention group, greater time spent teaching was significantly associated with correctly answered questions (p < .001). th...

Heart failure is associated with autonomic imbalance, and this can be evaluated by a spectral analysis of heart rate variability. However, the time course of low-frequency (LF) and high-frequency (HF) heart rate variability changes, and their functional correlates during progression of the disease are not exactly known. Progressive heart failure was induced in 16 beagle dogs over a 7-wk period ...
