Acute Heart Failure Management
Acute heart failure (AHF) is a life-threatening medical condition, where urgent diagnostic and treatment methods are of key importance. However, there are few evidence-based treatment methods. Interestingly, despite relatively similar ways of management of AHF throughout the globe, mid-term outcome in East Asia, including South Korea is more favorable than in Europe. Yet, most of the treatment methods are symptomatic. The cornerstone of AHF management is identifying precipitating factors and specific phenotype. Multidisciplinary approach is important in AHF, which can be caused or aggravated by both cardiac and non-cardiac causes. The main pathophysiological mechanism in AHF is congestion, both systemic and inside the organs (lung, kidney, or liver). Cardiac output is often preserved in AHF except in a few cases of advanced heart failure. This paper provides guidance on AHF management in a time-based approach. Treatment strategies, criteria for triage, admission to hospital and discharge are described.Peer reviewe
Prevalence, Temporal Evolution and Impact on Survival of Ventricular Conduction Blocks in Patients with Acute Coronary Syndrome and Cardiogenic Shock
Changes in QRS duration and pattern are regarded to reflect severe ischemia in acute coronary syndromes (ACS), and ventricular conduction blocks (VCBs) are recognized high-risk markers in both ACS and acute heart failure. Our aim was to evaluate the prevalence, temporal evolution, association with clinical and angiographic parameters, and impact on mortality of VCBs in ACS-related cardiogenic shock (CS). Data of 199 patients with ACS-related CS from a prospective multinational cohort were evaluated with electrocardiogram data from baseline and day 3. VCBs including left or right bundle branch block, right bundle branch block and hemiblock, isolated hemiblocks, and unspecified intraventricular conduction delay were assessed. Fifty percent of patients had a VCB at baseline; these patients were older, had poorer left ventricular function and had more often left main disease compared with those without VCB. One-year mortality was over 2-fold in patients with VCB compared with those without VCB (68% vs 32%, pPeer reviewe
Prognostic impact of baseline and residual SYNTAX scores in cardiogenic shock
Objectives The aim was to assess the extent of coronary artery disease and revascularization using baseline SYNTAX Score (bSS) and residual SYNTAX Score (rSS) in patients with cardiogenic shock (CS) secondary to ST-segment elevation myocardial infarction (STEMI). The prognostic impact of SYNTAX Score (SS) was evaluated and assessed for additive value over clinical risk scores. Background bSS and rSS have been proven to be useful in risk stratification in stable coronary artery disease as well as in acute coronary syndromes, but they have not been studied in STEMI related CS. Methods Patients from a multinational prospective study of CS were analyzed. The study population was divided into tertiles according to bSS. The Cox regression and receiver operating characteristic (ROC) curves were used to assess the predictive power of SS. Results Of the 61 studied patients, 85% were male and the mean age was 67 years. Median bSS was 22 (15-32) and rSS 7 (0-13). Ninety-day mortality was 43%. bSS had negative prognostic value in multivariable analysis (HR 1.06, 95% CI 1.01-1.10). However, additive value over clinical risk scores was limited. rSS was not associated with mortality, whereas post-percutaneous coronary intervention (PCI) TIMI flow 3 of infarct-related artery (IRA) predicted better survival. Conclusions In STEMI related CS, the added value of bSS and rSS over clinical assessment and risk scores is limited. Our results suggest that while immediate PCI in order to restore blood flow to the IRA is essential, deferring the treatment of residual lesions does not seem to be associated with worse prognosis.Peer reviewe
Hypoalbuminemia is a frequent marker of increased mortality in cardiogenic shock
Introduction The prevalence of hypoalbuminemia, early changes of plasma albumin (P-Alb) levels, and their effects on mortality in cardiogenic shock are unknown. Materials and methods P-Alb was measured from serial blood samples in 178 patients from a prospective multinational study on cardiogenic shock. The association of hypoalbuminemia with clinical characteristics and course of hospital stay including treatment and procedures was assessed. The primary outcome was all-cause 90-day mortality. Results Hypoalbuminemia (P-Alb < 34g/L) was very frequent (75%) at baseline in patients with cardiogenic shock. Patients with hypoalbuminemia had higher mortality than patients with normal albumin levels (48% vs. 23%, p = 0.004). Odds ratio for death at 90 days was 2.4 [95% CI 1.5–4.1] per 10 g/L decrease in baseline P-Alb. The association with increased mortality remained independent in regression models adjusted for clinical risk scores developed for cardiogenic shock (CardShock score adjusted odds ratio 2.0 [95% CI 1.1–3.8], IABP-SHOCK II score adjusted odds ratio 2.5 [95%CI 1.2–5.0]) and variables associated with hypoalbuminemia at baseline (adjusted odds ratio 2.9 [95%CI 1.2–7.1]). In serial measurements, albumin levels decreased at a similar rate between 0h and 72h in both survivors and nonsurvivors (ΔP-Alb -4.6 g/L vs. 5.4 g/L, p = 0.5). While the decrease was higher for patients with normal P-Alb at baseline (p<0.001 compared to patients with hypoalbuminemia at baseline), the rate of albumin decrease was not associated with outcome. Conclusions Hypoalbuminemia was a frequent finding early in cardiogenic shock, and P-Alb levels decreased during hospital stay. Low P-Alb at baseline was associated with mortality independently of other previously described risk factors. Thus, plasma albumin measurement should be part of the initial evaluation in patients with cardiogenic shock. Trial registration NCT01374867 at ClinicalTrials.gov.Peer reviewe

Levels of Growth Differentiation Factor 15 and Early Mortality Risk Stratification in Cardiogenic Shock
Background: The aim of this study was to assess the levels, kinetics, and prognostic value of growth differentiation factor 15 (GDF-15) in cardiogenic shock (CS). Methods and Results: Levels of GDF-15 were determined in serial plasma samples (0-120 h) from 177 CS patients in the CardShock study. Kinetics of GDF-15, its association with 90-day mortality, and incremental value for risk stratification were assessed. The median GDF-15(0h) level was 9647 ng/L (IQR 4500-19,270 ng/L) and levels above median were significantly associated with acidosis, hyperlactatemia, renal dysfunction, and higher 90-day mortality (56% vs 28%, P7000 ng/L was identified as a strong predictor of death (OR 5.0; 95% CI 1.9-3.8, P=.002). Adding GDF-15(12h) >7000 ng/L to the CardShock risk score improved discrimination and risk stratification for 90-day mortality. Conclusions: GDF-15 levels are highly elevated in CS and associated with markers of systemic hypoperfusion and end-organ dysfunction. GDF-15 helps to discriminate survivors from non-survivors very early in CS.Peer reviewe
