INTRODUCTION Accidental hypothermia is a condition associated with significant morbidity and mortality. Hypothermia has been reported to affect left ventricular systolic and diastolic function. However, most of the data come from animal experimental studies. AIM OF THE STUDY The purpose of the present study was to assess the impact of severe accidental hypothermia on systolic and diastolic ve...

Objective To determine if vitamin D deficiency was associated with higher odds of left ventricular dysfunction among patients with acute coronary syndrome (ACS) and, if so, to determine whether this association was mediated by increased inflammation as measured by C-reactive protein (CRP) and white blood cell count (WBC). Methods This was a cross-sectional study of 170 participants with ACS. ...

Background: There are some conflicting results with Conventional Coronary Artery Bypass Grafts (CCABG) with arrested heart in coronary high-risk patients. Moreover, performing off-pump CABG in these cases may be associated with serious complications. The objective of this study is to evaluate the efficacy of the on-pump beating CABG (OPBCABG) in coronary high-risk patients in comparison with th...

Anaphylaxis is an acute, severe systemic allergic reaction that can be potentially fatal. It often transition to refractory hemodynamic instability (new onset myocardial dysfunction/ left ventricular dysfunction/LVD). Stress-related cardiomyopathy (SRC) now emerging as a significant contributor of dysfunction and has multifactorial etiologies, including the excessive catecholamine released in i...

BACKGROUND N-terminal pro-B-type natriuretic peptide (NT-proBNP) testing is useful for diagnosing acute decompensated heart failure. Whether NT-proBNP can be used to detect ventricular dysfunction in patients with stable coronary heart disease (CHD) and no history of heart failure is unknown. METHODS We measured NT-proBNP levels and performed transthoracic echocardiography in 815 participants...

The peculiar shape of the right ventricle (RV), its position within the chest, and the thinness of its free wall have always represented a formidable challenge for the assessment of RV size and function by conventional 2-dimensional echocardiography. Over time, a large number of 2D echocardiography and Doppler parameters have been proposed to describe RV geometry and function. However, most of ...

background: left ventricular (lv) twist is due to oppositely directed apical and basal rotation and has been proposed as a sensitive marker of lv function. we sought to assess the impact of chronic pure mitral regurgitation (mr) on the torsional mechanics of the left human ventricle using tissue doppler imaging. methods: nineteen severe mr patients with a normal lv ejection fraction and 16 non-...

BACKGROUND Left ventricular ejection fraction remains the primary risk stratification tool used in the selection of patients for implantable cardioverter defibrillator therapy. However, this solitary marker fails to identify a substantial portion of patients experiencing sudden cardiac arrest. In this study, we examined the incremental value of considering right ventricular ejection fraction fo...
