Prognostic implication of physical signs of congestion in acute heart failure patients and its association with steady-state biomarker levels.

ABSTRACT:

Background

Congestive physical findings such as pulmonary rales and third heart sound (S3) are hallmarks of acute heart failure (AHF). However, their role in outcome prediction remains unclear. We sought to investigate the association between congestive physical findings upon admission, steady-state biomarkers at the time of discharge, and long-term outcomes in AHF patients.

Methods

We analyzed the data of 133 consecutive AHF patients with an established diagnosis of ischemic or non-ischemic (dilated or hypertrophic) cardiomyopathy, admitted to a single-center university hospital between 2006 and 2010. The treating physician prospectively recorded major symptoms and congestive physical findings of AHF: paroxysmal nocturnal dyspnea, orthopnea, pulmonary rales, jugular venous distension (JVD), S3, and edema. The primary endpoint was defined as rehospitalization for HF.

Results

Majority (63.9%) of the patients had non-ischemic etiology and, at the time of admission, S3 was seen in 69.9% of the patients, JVD in 54.1%, and pulmonary rales in 43.6%. The mean follow-up period was 726 ± 31 days. Patients with pulmonary rales (p < 0.001) and S3 (p ?=? 0.011) had worse readmission rates than those without these findings; the presence of these findings was also associated with elevated troponin T (TnT) levels at the time of discharge (odds ratio [OR] 2.8; p ?=? 0.02 and OR 2.6; p ?=? 0.05, respectively).

Conclusion

Pulmonary rales and S3 were associated with inferior readmission rates and elevated TnT levels on discharge. The worsening of the readmission rate owing to congestive physical findings may be a consequence of on-going myocardial injury.

Project description:BACKGROUND:The relationship between changes in serum sodium with clinical events in acute heart failure patients using different decongestive events has not been investigated. This study aimed to describe changes in serum sodium levels during decongestion therapy in patients receiving stepped pharmacological therapy versus ultrafiltration. METHODS AND RESULTS:We studied 188 patients who were enrolled in the CARRESS-HF trial (Cardiorenal Rescue Study in Acute Decompensated Heart Failure). Treatment-induced hyponatremia was defined as admission normonatremia (?135 mEq/L) with a subsequent decrease (<135 mEq/L) during hospitalization. Patients treated with ultrafiltration had significantly lower sodium levels than those with conventional treatment at days 1, 4, and 7 (all P<0.01), whereas those at day 30 were similar between the groups. Changes in sodium levels in patients with ultrafiltration were negatively correlated to those in serum creatinine and plasma renin activity. The incidence of treatment-induced hyponatremia was significantly higher in the ultrafiltration group than those receiving conventional treatment (P=0.002). Although patients with discharge hyponatremia had a higher risk for composite end point of all-cause death, rehospitalization, or unscheduled hospital visit in comparison to those without (adjusted hazard ratio, 2.01; 95% confidence interval, 1.09-3.70; P=0.025), the risk was comparable between patients with treatment-induced hyponatremia and those who did not experience any hyponatremia (adjusted hazard ratio, 0.99; 95% confidence interval, 0.50-1.96; P=0.99). CONCLUSIONS:Fluid removal by ultrafiltration was associated with a decrease in serum sodium levels compared with diuretic treatment but returned to baseline levels at day 30. Discharge hyponatremia but not treatment-induced hyponatremia was associated with worse clinical outcomes. CLINICAL TRIAL REGISTRATION:URL: http://www.clinicaltrials.gov.

Project description:AimsInsulin-like growth factor binding protein-4 (IGFBP-4) fragments have been shown to predict the risk of major adverse cardiovascular events, including segment-elevation myocardial infarction, in patients with acute coronary syndrome. We evaluated the prognostic value of the carboxy-terminal fragment of IGFBP-4 (CT-IGFBP-4) for all-cause mortality in emergency room patients with acute heart failure (AHF).Methods and resultsCT-IGFBP-4, N-terminal pro brain natriuretic peptide (NT-proBNP), and C-reactive protein (CRP) were measured at admission from the lithium-heparin plasma of 156 patients with AHF. All-cause mortality was recorded for 1 year. Receiver operator characteristic (ROC) curves, Kaplan-Meier, and Cox proportional hazard ratio analyses were performed to evaluate the prognostic value of the various clinical variables, CT-IGFBP-4, NT-proBNP, CRP, and their combinations. During 1 year of follow-up, 52 (33.3%) patients died. CT-IGFBP-4 only weakly correlated with NT-proBNP (Pearson correlation coefficient r = 0.16, P = 0.044) and did not correlate with CRP (r = 0.08, P = 0.35), emphasizing the different nature of these biomarkers. The receiver operator characteristic area under the curve (ROC AUC) of CT-IGFBP-4 for the prediction of all-cause mortality (0.727) was significantly higher than that of NT-proBNP (0.680, P = 0.045) and CRP (0.669, P = 0.016). The combination of CT-IGFBP-4, NT-proBNP, and CRP predicted mortality significantly better (ROC AUC = 0.788) than any of the biomarkers alone (P < 0.01 for all). The addition of CT-IGFBP-4 to a clinical prediction model that included age, gender, systolic blood pressure, creatinine, and sodium levels, as well as the history of previous heart failure, coronary artery disease, and hypertension significantly improved the mortality risk prediction (ROC AUC 0.774 vs. 0.699, P = 0.025). Cox hazard analysis indicated that elevated CT-IGFBP-4 was independently associated with 1 year mortality (hazard ratio 3.26, P = 0.0008) after adjustment for age, gender, history of previous heart failure, coronary artery disease, hypertension, chronic kidney failure, history of diabetes, heart rate, haemoglobin, plasma sodium, NT-proBNP, CRP, cystatin C, and elevated cardiac troponin I or T. Patients with increased levels of either two or three of the biomarkers CT-IGFBP-4, NT-proBNP, and CRP had significantly higher mortality risk (adjusted hazard ratio 10.04, P < 0.0001) than patients with increased levels of one or none of the biomarkers.ConclusionsCT-IGFBP-4 was independently associated with all-cause mortality in patients with AHF. Compared with single biomarkers, the combination of CT-IGFBP-4, NT-proBNP, and CRP improved the prediction of all-cause mortality in patients with AHF.
