Thirty patients undergoing epirubicin therapy for primary lung cancer were studied by echocardiography and Doppler echocardiography. 2 D ejection fraction (EF) and Doppler left ventricular filling parameters (peak E, peak A, E/A ratio) were calculated before and after the completion of therapy. No differences in the mean values of these parameters were observed. However, 6 out of 30 patients (20%) showed left ventricular filling abnormalities; in 2 of them a slight reduction of EF was also noted. These abnormalities seem to be dose related. A longer term prospective study will be required to evaluate whether these findings are irreversible and to establish the clinical implications of our observations.

Background: Reduced insulin secretion is linked to diabetes and cardiovascular disease (CVD), but its role in non-diabetic CVD patients is unclear. The homeostasis model assessment of β-cell function (HOMA-β) measures pancreatic β-cell function. This study investigated the association between HOMA-β and adverse cardiovascular events in non-diabetic CVD patients.

Our patient presented to the emergency room following a motor vehicle accident. The traumatic tricuspid valve rupture was diagnosed by transthoracic echocardiogram, and his respiratory status declined rapidly. He was placed on veno-venous extracorporeal membrane oxygenation (VV ECMO) to bridge him to surgical repair.

Background: Early heart failure (HF) diagnosis is crucial to ensure that optimal guideline-directed medical therapy (GDMT) is administered to reduce morbidity and mortality. Limited access to echocardiography could lead to a later diagnosis for patients, for example, during an HF hospitalisation (hHF). This study aimed to compare the incidence and outcomes of inpatient versus outpatient diagnosis of HF.

Gazi University, Faculty of Medicine, Department of Endocrinology and Metabolism, Ankara, Turkey. Electronic address:
Aim: Co-existing primary aldosteronism (PA) and autonomous cortisol secretion (ACS) has been recently recognized as a distinct entity. This study aimed to assess the incidence of ACS in patients with PA, and its impact on clinical and laboratory parameters.
Methods: Ninety-two patients diagnosed with PA were included.
