Two-dimensional echocardiography and gated blood radionuclide angiography was performed in 50 patients (mean age 51.3 years; 48 men and 2 women) after acute myocardial infarction, before discharge from the hospital. The aim of this study was to compare the wall motion score, determined by two-dimensional echocardiography (2DE), with the ejection fraction obtained by radionuclide angiography (RNA). The correlation between the results obtained by 2DE and RNA was good (r = 0.75; p less than 0.0001). We conclude that 2DE is a powerful diagnostic tool for the evaluation of left ventricular function.

Backgrounds: Due to the high mortality and hospitalization rate in chronic heart failure (HF), it is of great significance to study myocardial nutrition conditions. Amino acids (AAs) are essential nutrient metabolites for cell development and survival. This study aims to investigate the associations and prognostic value of plasma branched-chain amino acid/aromatic amino acid ratio (Fischer's ratio, FR) in patients with left ventricular ejection fraction (LVEF) ≤ 50%.

Persistent myocardial impairment proved by histopathologic studies universally existed in patients with Kawasaki disease (KD); however, the long-term effects on myocardial contractile reserve in KD patients, especially on patients without coronary artery lesions (CALs), is still unknown. The aim of this study was to investigate myocardial contractile reserve in KD patients during late convalescent stage by speckle-tracking adenosine triphosphate (AT) echocardiography. A total of 63 antecedent KD patients at least 4 years after the disease onset and 40 age- and gender-matched normal controls were prospectively enrolled.

Background Neonatal vascular air embolism is a rare but often fatal condition. The literature comprises mostly case reports and a few dated systematic reviews. Our objective was to review all case reports of neonatal vascular air embolism to date, and provide up-to-date information about patient characteristics, clinical presentations, outcomes, pathogenesis, diagnosis, prevention, treatment and prognosis.

Background: RV reserve has been linked to exercise capacity and prognosis in cardiopulmonary diseases. However, evidence in this setting is limited, due to the complex shape and load dependency of the RV. We sought to study right ventricular (RV) adaptation to exercise by simultaneous three-dimensional echocardiography (3DE) and right heart catheterization (RHC).
