ABSTRACT
BACKGROUND: Chronic kidney disease (CKD) is associated with higher incidence of cardiovascular death. Screening for coronary artery disease in asymptomatic or mildly symptomatic patients is challenging. OBJECTIVE: The aim of this study was to investigate the incremental value of resting deformation analysis in predicting positive results for myocardial ischemia during stress transthoracic echocardiography in patients with end-stage CKD. METHODS: Sixty-one patients (mean age: 62.3 ± 11.8, 65.7% men) with end-stage CKD were included in the study. Patients underwent a resting transthoracic echocardiogram and a dobutamine stress contrast echo (DSE) protocol. Positive results of DSE were defined as stress-induced left ventricular (LV) wall motion abnormalities. RESULTS: The study cohort had normal or mildly impaired systolic function: mean LV ejection fraction (EF) was 49.2% (±10.4) and mean LV global longitudinal strain (GLS) was 14.4% (±4.5). Half of our population had impaired left atrial (LA) strain: mean LA reservoir, conduit, and contractile reserve were 24.1% (±12.6), 10.6% (±5.9), and 13.6% (±9.2), respectively. DSE was positive for ischemia in 55.7%. A significant negative association with DSE results was found for LV EF, LV GLS and the conduit phase of LA strain. Both LV and LA dimensions showed positive correlation with presence of ischemia in DSE. Multivariate logistic regression analysis showed that LV GLS was independently associated with DSE (p = 0.007), after controlling for covariates, with high diagnostic accuracy. CONCLUSION: Resting LV deformation could predict positive results during DSE, thus may be useful to better identify renal patients who might benefit from coronary artery screening.

BACKGROUND AND AIMS: Cardiovascular complications of liver cirrhosis include high cardiac output heart failure with reduced afterload and diastolic dysfunction. Heart Failure Association Pre-test assessment, Echocardiography and natriuretic peptide, Functional testing, Final etiology (HFA-PEFF) (values 0-6) is a diagnostic tool for heart failure. It is a cluster of echocardiographic and biochemical parameters. The purpose of this prospective study was to assess if HFA-PEFF score is associated with the severity of liver disease and to determine its prognostic significance in patients with cirrhosis. METHODS: Patients with cirrhosis without an acute event were enrolled. A comprehensive echocardiography study was conducted, brain natriuretic peptide and N-terminal-pro-B-type Natriuretic Peptide levels were measured and HFA-PEFF score was calculated. All patients were prospectively followed up after enrollment. The study end-point was defined as the composite of all-cause death. RESULTS: Seventy-two consecutive patients [median age 59 years (inter-quartile range: 52-65), 72.2% males, Model for End-stage Liver Disease (MELD) 12.9 (8.5-16.3)] were included. The 52.8% had a high HFA-PEFF score (5 or 6) and the 47.2% intermediate/low score (0-4). HFA-PEFF score was correlated with MELD score (rho = 0.566, P < 0.001), but not with age, SBP and heart rate. The median follow-up was 24.2 (9.5-38.8) months. The 1- and 2-year cumulative mortality was higher in patients with high HFA-PEFF compared to those with intermediate/low (log-rank P < 0.001 for both). The predicted 2-year probability of survival in high vs intermediate/low HFA-PEFF was found to be a prognostic factor of death even when adjusted for age, gender and MELD score [hazard ratio = 3.539 (1.134-11.046), P = 0.029]. CONCLUSION: HFA-PEFF score is high among patients with liver cirrhosis, especially those with advanced liver disease. HFA-PEFF score is associated with survival even when adjusting for cirrhosis severity.

A case of a patient with liver cirrhosis and a large left-sided pleural effusion displacing the heart rightward is presented and the best views to acquire images enabling evaluation of the cardiac function are highlighted. Understanding the modified intrathoracic anatomy in patients with pleural effusions enables quick and focused assessment and can shorten evaluation time while preserving high image quality.
