The prevalence of heart failure (HF) is on the rise due to the aging of society. Furthermore, the continuous progress and widespread adoption of screening and diagnostic strategies have led to an increase in the detection rate of HF, effectively increasing the number of patients requiring monitoring and treatment. Because HF is associated with substantial rates of mortality and morbidity, as well as high socioeconomic burden, there is an increasing need for developing specific guidelines for HF management. The Korean guidelines for the diagnosis and management of chronic HF were introduced in March 2016. However, chronic and acute heart failure (AHF) represent distinct disease entities. Here, we introduce the Korean guidelines for the management of AHF with reduced or preserved ejection fraction. Part I of this guideline covers the definition, epidemiology, and diagnosis of AHF.

Hypertension affects the majority of patients with chronic kidney disease (CKD) and increases the risk of cardiovascular disease, end-stage renal disease and mortality. Previously, many hypertension guidelines have suggested blood pressure targets in patients with CKD. Recently, the American College of Cardiology/American Heart Association 2017 Guideline for Hypertension suggests a new definition for hypertension and therapeutic targets, which were equally applicated to patients with CKD. These changes reflect the results of the Systolic Blood Pressure Intervention Trial (SPRINT) study, but the renal outcome of intensive blood pressure control was not good. Furthermore, the majority of hypertension guidelines including those of the Korean Society of Hypertension and the European Society of Hypertension have retained the traditional definition. Herein, we intend to analyze in detail the effect of intensive blood pressure control on kidney through the post-hoc analyses of the SPRINT study.

Heart failure (HF) is an important cardiovascular disease because of its increasing prevalence, significant morbidity, high mortality, and rapidly expanding health care cost. The number of HF patients is increasing worldwide, and Korea is no exception. There have been marked advances in definition, diagnostic modalities, and treatment of HF over the past four decades. There is continuing effort to improve risk stratification of HF using biomarkers, imaging and genetic testing. Newly developed medications and devices for HF have been widely adopted in clinical practice. Furthermore, definitive treatment for end-stage heart failure including left ventricular assist device and heart transplantation are rapidly evolving as well. This review summarizes the current state-of-the-art management for HF and the emerging diagnostic and therapeutic modalities to improve the outcome of HF patients.

PURPOSE: Readmission and mortality rates of patients with heart failure are good indicators of care quality. To determine whether hospital resources are associated with care quality for cardiac patients, we analyzed the effect of number of physicians and the combined effects of number of physicians and beds on 30-day readmission and 1-year mortality. MATERIALS AND METHODS: We used national cohort sample data of the National Health Insurance Service (NHIS) claims in 2002–2013. Subjects comprised 2345 inpatients (age: >65 years) admitted to acute-care hospitals for heart failure. A multivariate Cox regression was used. RESULTS: Of the 2345 patients hospitalized with heart failure, 812 inpatients (34.6%) were readmitted within 30 days and 190 (8.1%) had died within a year. Heart-failure patients treated at hospitals with low physician volumes had higher readmission and mortality rates than high physician volumes [30-day readmission: hazard ratio (HR)=1.291, 95% confidence interval (CI)=1.020–1.633; 1-year mortality: HR=2.168, 95% CI=1.415–3.321]. Patients admitted to hospitals with low or middle bed and physician volume had higher 30-day readmission and 1-year mortality rates than those admitted to hospitals with high volume (30-day readmission: HR=2.812, 95% CI=1.561–5.066 for middle-volume beds & low-volume physicians, 1-year mortality: HR=8.638, 95% CI=2.072–36.02 for middle-volume beds & low-volume physicians). CONCLUSION: Physician volume is related to lower readmission and mortality for heart failure. Of interest, 30-day readmission and 1-year mortality were significantly associated with the combined effects of physician and institution bed volume.

Acute heart failure is a common complication of chronic heart failure and is associated with a high risk for subsequent mortality and morbidity. In 90% of case acute heart failure is the resultant of congestion, a manifestation of fluid build-up due to increased filling pressures. As residual congestion at discharge following an acute heart failure episodes is one of the strongest predictors of poor outcome, the goal of therapy should be to resolve congestion completely. Important to comprehend is that increased cardiovascular filling pressures are not solely the resultant of intravascular volume excess but can also be induced by a decreased venous capacitance. This review article focusses on the pathophysiology, diagnoses, and treatment of congestion in acute heart failure. A clear distinction is made between states of volume overload (intravascular volume excess) or volume redistribution (decreased venous capacitance) contributing to congestion in acute heart failure.

The prevalence of heart failure (HF) is rapidly increasing throughout the world, and is closely associated with serious morbidity and mortality. In particular, acute HF is one of the main causes of hospitalization and mortality, especially in elderly individuals. In Korea, the socioeconomic burden of HF is substantial. Because of this, the Korean HF society developed chronic and acute HF management guidelines in 2017, adapted process while including as much data from Korean studies as possible. The scope of the current review, which is based on the Korean HF guidelines, includes the definition, diagnosis, and treatment of acute HF with reduced or preserved ejection fractions of various etiologies.

The prevalence of heart failure (HF) is skyrocketing worldwide, and is closely associated with serious morbidity and mortality. In particular, HF is one of the main causes for the hospitalization and mortality in elderly individuals. Korea also has these epidemiological problems, and HF is responsible for huge socioeconomic burden. However, there has been no clinical guideline for HF management in Korea. 
The present guideline provides the first set of practical guidelines for the management of HF in Korea and was developed using the guideline adaptation process while including as many data from Korean studies as possible. The scope of the present guideline includes the definition, diagnosis, and treatment of chronic HF with reduced/preserved ejection fraction of various etiologies.

INTRODUCTIONWe assessed the local prevalence, characteristics and 10-year outcomes in a heart failure (HF) cohort from the emergency room (ER).

MATERIALS AND METHODSPatients presenting with acute dyspnoea to ER were prospectively enrolled from December 2003 to December 2004. HF was diagnosed by physicians' adjudication based on clinical assessment and echocardiogram within 12 hours, blinded to N-terminal-pro brain natriuretic peptide (NT-proBNP) results. They were stratified into heart failure with preserved (HFPEF) and reduced ejection fraction (HFREF) by left ventricular ejection fraction (LVEF).

RESULTSAt different cutoffs of LVEF of ≥50%, ≥45%, ≥40%, and >50% plus excluding LVEF 40% to 50%, HFPEF prevalence ranged from 38% to 51%. Using LVEF ≥50% as the final cutoff point, at baseline, HFPEF (n = 35), compared to HFREF (n = 55), had lower admission NT- proBNP (1502 vs 5953 pg/mL, P <0.001), heart rate (86 ± 22 vs 98 ± 22 bpm, P = 0.014), and diastolic blood pressure (DBP) (75 ± 14 vs 84 ± 20 mmHg, P = 0.024). On echocardiogram, compared to HFREF, HFPEF had more LV concentric remodelling (20% vs 2%, P = 0.003), less eccentric hypertrophy (11% vs 53%, P <0.001) and less mitral regurgitation from functional mitral regurgitation (60% vs 95%, P = 0.027). At 10 years, compared to HFREF, HFPEF had similar primary endpoints of a composite of cardiovascular death, non-fatal myocardial infarction, non-fatal stroke, and rehospitalisation for congestive heart failure (CHF) (HR 0.886; 95% CI, 0.561 to 1.399; P = 0.605), all-cause mortality (HR 0.663; 95% CI, 0.400 to 1.100; P = 0.112), but lower cardiovascular mortality (HR 0.307; 95% CI, 0.111 to 0.850; P = 0.023).

CONCLUSIONIn the long term, HFPEF had higher non-cardiovascular mortality, but lower cardiovascular mortality compared to HFREF.
