Semi-quantitative pulmonary congestion score: prevalence and diuretic management implications after heart failure discharge.

INTRODUCTION: Persistent congestion after heart failure (HF) discharge is associated with a higher risk of readmissions. MATERIAL AND METHODS: eighty-two patients included after HF discharge. The aim of the study was to characterize semiquantitatively the degree of pulmonary congestion and its changes, describing the relationship between these findings and diuretic management. RESULTS: On the first visit, despite the absence of clinical congestion in the majority of patients, half of the had some degree of pulmonary congestion by ultrasound. After global assessment in this initial visit (clinical and ultrasound) the diuretic was lowered in 50 patients (60%), kept the same in 16 (20%) and it was increased in the rest. In the 45 patients without ultrasound congestion, diuretic reduction was attempted in 80%, being this strategy successful in the majority of them. CONCLUSIONS: Lung ultrasound, using simple quantification methods, allows its real incorporation into clinical practice, helping us in the decision making process.

Serial monitoring of soluble interleukin family member ST2 in patients with acutely decompensated heart failure.

OBJECTIVES: To determine whether serial measures of the interleukin receptor family member soluble ST2 (sST2) provide additional prognostic information to baseline measures for long-term risk stratification of acutely decompensated heart failure (ADHF) patients. METHODS: We prospectively enrolled 72 ADHF patients. Blood samples were collected to measure sST2 concentrations at presentation and on day 4 of hospitalization. All patients were clinically followed, and vital status was registered. RESULTS: Between presentation and day 4, sST2 concentrations decreased from 62 ng/ml (interquartile range 38-105) to 44 ng/ml (interquartile range 26-72; p < 0.001). Both sST2 concentrations at presentation [hazard ratio (HR) 1.011, 95% confidence interval (CI) 1.005-1.016; p < 0.001] and on day 4 (HR 1.015, 95% CI 1.005-1.024; p = 0.003) were independent predictors of mortality. Patients with sST2 ≤ 76 ng/ml at presentation and ≤ 46 ng/ml on day 4 had the lowest mortality rates (3%), whereas those with both sST2 values above these cutoff points had the highest mortality (50%). C index and reclassification analyses demonstrated that the use of serial sST2 measures resulted in an improvement in the accuracy of mortality prediction. CONCLUSIONS: Among ADHF patients, sST2 concentrations tend to decrease following initiation of treatment and are prognostic both at presentation and during hospitalization. Serial sampling of sST2 adds prognostic information and may provide a basis for enhanced clinical decision making.

Additive value of diabetes and peripheral arterial disease in the risk stratification of patients admitted after an acute coronary syndrome: a subanalysis of the PAMISCA Study.

BACKGROUND: There is an increasing interest in the use of non-invasive methods for the detection of subclinical atherosclerosis to better identify patients with high risk of cardiovascular events The presence of diabetes mellitus (DM) and peripheral arterial disease (PAD) is associated with increased risk of events but their value in the acute coronary syndrome (ACS) patient has not been ascertained. METHODS: We performed a subanalysis of the PAMISCA study, designed to investigate the prevalence of PAD in patients admitted to Spanish hospitals with a diagnosis of an ACS. RESULTS: A total of 1410 patients were analysed (71.4% men, age 66 +/- 11.9 years, 35% DM). The prevalence of PAD was higher in DM vs. no-DM (41.5% vs. 30.6% respectively, p < 0.001). Patients with PAD and DM had more in-hospital cardiac complications such as atrial fibrillation/flutter, recurrent myocardial ischaemia and heart failure and a trend towards higher in-hospital mortality (p = 0.08). Non-DM patients with PAD and DM without PAD shared similar cardiac complications and the group without neither PAD nor DM had the best prognosis. In patients without PAD, DM was an independent predictor of three-vessel coronary disease (OR 1.6; 95% CI: 1.1-2.5, p < 0.05) after adjustment by age, sex, low density lipoproteins (LDL), smoking and the previous myocardial infarction. However, in PAD patients, DM failed to be an independent risk factor in the multivariate analysis (OR 1.0; 95% CI 0.6-1.6, p < 0.05). CONCLUSIONS: The concurrence of DM and PAD helps identify patients with an adverse risk profile.
