Abstract Background Lung ultrasound (LUS) detects pulmonary congestion as B-lines at rest and exercise stress echocardiography (ESE). Aim To assess the prevalence of B-lines during ESE in different cardiovascular diseases. Methods We performed ESE plus LUS (4-site simplified scan) in 4419 subjects referred for semi-supine bike ESE in 28 certified centers. B-lines score ranged from 0 (normal) to 40 (severely abnormal). Stress B-lines abnormal result was ≥2 units. Six different populations were evaluated: healthy controls (n=103); chronic coronary syndromes (CCS, n=3701); heart failure with reduced ejection fraction (HFrEF, n=395); heart failure with preserved ejection fraction (HFpEF, n=70); valvular heart disease (VHD) for ischemic mitral regurgitation ≥moderate at rest (n=123); repaired tetralogy of Fallot (ToF, n=27). Results Feasibility of B-lines was 100% at rest and peak ESE in all subjects. Imaging and analysis time were <1 minute. B-lines (median) were not detectable in healthy subjects (rest=0.1 [0–1] vs 0.1 [0–1], p=ns) and TOF (rest=0.2 [0–2] vs 0.3 [0–4], p=ns), but were present in all other groups: see figure. During ESE, B-lines increased in CCS (rest=0.5 [0–24] vs ESE=1.3 [0–28], p<0.001); HFrEF (rest=1.4 [0–35] vs ESE=2.9 [0–40], p<0.001); HFpEF (rest=0.3 [0–2] vs ESE=3.4 [0–12], p<0.001), VHD (rest=1.7 [0–12] vs ESE=4.3 [0–23], p<0.001). Stress B-lines were correlated with stress-rest change in wall motion score index in CCS (r=0.325, p<0.001), contractile reserve in HFrEF (r=−0.266, p<0.001) and in VHD (r=−.0300, p=0.001), left atrial volume stress-rest change in HFpEF (r=0.287, p=0.043). Conclusion B-lines identify the pulmonary congestion phenotype at rest and more frequently during ESE in patients with different coronary, myocardial or valvular heart disease, all sharing the final common pathway of acute backward left heart failure through different disease-specific mechanisms. B-lines are absent in healthy subjects and in conditions inducing a mostly right-sided overload such as repaired ToF. FUNDunding Acknowledgement Type of funding sources: None. Figure 1.

Abstract Aims  Cardiac power is a measure of cardiac performance that incorporates both pressure and flow components. Prior studies have shown that cardiac power predicts outcomes in patients with reduced left ventricular (LV) ejection fraction (EF). We sought to evaluate the prognostic significance of peak exercise cardiac power and power reserve in patients with normal EF. Methods and results  We performed a retrospective analysis in 24 885 patients (age 59 ± 13 years, 45% females) with EF ≥50% and no significant valve disease or right ventricular dysfunction, undergoing exercise stress echocardiography between 2004 and 2018. Cardiac power and power reserve (developed power with stress) were normalized to LV mass and expressed in W/100 g of LV myocardium. Endpoints at follow-up were all-cause mortality and diagnosis of heart failure (HF). Patients in the higher quartiles of power/mass (rest, peak stress, and power reserve) were younger and had higher peak blood pressure and heart rate, lower LV mass, and lower prevalence of comorbidities. During follow-up [median 3.9 (0.6–8.3) years], 929 patients died. After adjusting for age, sex, metabolic equivalents (METs) achieved, ischaemia/infarction on stress test results, medication, and comorbidities, peak stress power/mass was independently associated with mortality [adjusted hazard ratio (HR), highest vs. lowest quartile, 0.5, 95% confidence interval (CI) 0.4–0.6, P < 0.001] and HF at follow-up [adjusted HR, highest vs. lowest quartile, 0.4, 95% CI (0.3, 0.5), P < 0.001]. Power reserve showed similar results. Conclusion  The assessment of cardiac power during exercise stress echocardiography in patients with normal EF provides valuable prognostic information, in addition to stress test findings on inducible myocardial ischaemia and exercise capacity.

Wedge Pressure

Background: An elevated pulmonary artery wedge pressure (PAWP), a surrogate of left ventricular filling pressure, is associated with poor outcomes in patients with heart failure (HF). In addition, obesity paradox is well recognized in HF patients and body mass index (BMI) also provides a prognostic information. However, there is little information available on the prognostic value of the combination of the echocardiographic derived PAWP and BMI in patients with HF with preserved ejection fraction (HFpEF). Methods and Results: Patients data were extracted from The Prospective mUlticenteR obServational stUdy of patIenTs with Heart Failure with Preserved Ejection Fraction (PURSUIT HFpEF) study, which is a prospective multicenter observational registry for acute decompensated heart failure (ADHF) patients with HFpEF. We analyzed 548 patients after exclusion of patients undergoing hemodialysis, patients with in-hospital death, missing follow-up data, or missing data to calculate PAWP or BMI. Body weight measurement and echocardiography were performed just before discharge. PAWP was calculated using the Nagueh formula [PAWP = 1.24* (E/e’) + 1.9] with e’ = [(e’ septal + e’ lateral ) /2]. During a mean follow up period of 1.5±0.8 years, 86 patients had all-cause death (ACD). Multivariate Cox analysis showed that both PAWP (p=0.020) and BMI (p=0.0001) were significantly associated with ACD, independently of age and previous history of HF hospitalization, after the adjustment with gender, left ventricular ejection fraction, NT-proBNP and estimated glomerular filtration rate. Kaplan-Meier curve analysis revealed that there was a significant difference in the risk of ACD when patients were stratified into 3 groups based on the median values of PAWP (17.3) and BMI (21.4). Conclusions: The combination of the echocardiographic derived PAWP and BMI might be useful for stratifying ADHF patients with HFpEF at risk for the total mortality.
