BACKGROUNDS We investigated the relationship between spironolactone use and all-cause mortality in acute decompensated heart failure (ADHF) patients with severe renal dysfunction. The clinical benefit of spironolactone in the treatment of heart failure (HF) has been described in several large randomized clinical trials. However, its clinical benefits have(More)
BACKGROUND Hemoconcentration is a surrogate marker of effective decongestion and diuresis therapy. Recently, hemoconcentration has been associated with decreased mortality and rehospitalization in heart failure (HF) patients. However, the prognostic power of hemoconcentration in a large sample-sized HF cohort was limited until now. METHODS AND RESULTS We(More)
BACKGROUND Hypercholesterolemia is a major risk factor for incident coronary artery disease and the prevalence of heart failure (HF). The causal relationship between low total cholesterol (TC) levels and poor clinical outcome in patients with acute HF has not been investigated. This study evaluated the effect of cholesterol levels on the long-term outcome(More)
BACKGROUND AND OBJECTIVES Acute heart failure (AHF) is associated with a poor prognosis and it requires repeated hospitalizations. However, there are few studies on the characteristics, treatment and prognostic factors of AHF. The aims of this study were to describe the clinical characteristics, management and outcomes of the patients hospitalized for AHF(More)
OBJECTIVES A prolonged QRS duration has been associated with an unfavorable prognosis in chronic compensated heart failure (HF). However, its predictive value during an admission for acute HF is limited, even in HF with a preserved ejection fraction (EF). The purpose of this study was to evaluate the prognostic utility of the QRS duration in acute HF. (More)

Heart failure (HF) is an important cardiovascular disease because of its increasing prevalence, significant morbidity, high mortality and rapidly expanding health care costs. The number of HF patients is increasing worldwide and Korea is no exception. Temporal trends of four representative Korean hospitalized HF registries-the Hallym HF study, the Korean(More)
BACKGROUND AND OBJECTIVES Metabolic syndrome (MetS) increases the risk of heart failure (HF). The purpose of this study was to identify the prevalence of MetS in patients with HF and determine the syndrome's association with HF in clinical and laboratory parameters. SUBJECTS AND METHODS A total of 3200 HF patients (67.6±14.5 years) enrolled in a(More)
Heart failure (HF) is an important cardiovascular disease because of its increasing prevalence, significant morbidity, high mortality, and rapidly expanding health care costs.1) Acute heart failure (AHF) refers to rapid onset or worsening of symptoms and/or signs of HF. It is a life-threatening medical condition requiring urgent evaluation and treatment,(More)
