Independent value of left atrial volume index for the prediction of mortality in patients with suspected heart failure referred from the community.

Increased left atrial volume index is an independent predictor of raised serum natriuretic peptide in patients with suspected heart failure but normal left ventricular ejection fraction: Implication for diagnosis of diastolic heart failure.

BACKGROUND Left atrial volume index (LAVI) is increasingly recognised as a relatively load-independent marker of left ventricular (LV) filling pressures. We assessed the capacity of LAVI to predict LV diastolic dysfunction in comparison with N-terminal pro B-type natriuretic peptide (NTproBNP) in patients with suspected heart failure and a normal ejection fraction (EF). METHODS 137 patients w...

  Background & Objective : Heart failure is a clinical syndrome and increases in rate by aging. Because changes in ECG and electrolytes are variable, specific and sometimes independent to the disease with different methods to be diagnosed, in this study we tried to find a way to diagnose them.   Materials & Methods: This is a retrospective descriptive-analytic study. Data was collected from dec...

Clinical Significance of P Wave Dispersion in Prediction of Atrial Fibrillation in Patients with Acute Myocardial Infarction

Background: P wave dispersion (PWD) is defined as the difference between the maximum P wave duration (Pmax) and the minimum P wave duration (Pmin) in 12-leads of the surface electrocardiography. The aim of this study was to evaluate the values of PWD during atrial fibrillation (AF) after acute myocardial infarction (AMI). Methods: We prospectively evaluated atrial rhythms of 350 patients (251 m...

Association between Body Mass Index and Mitral Valve Prolapse

Introduction: Body mass index (BMI) can affect cardiac morphology; however, the relationship between BMI and valvular heart diseases has not been thoroughly evaluated. This study aimed to determine the relationship between BMI and mitral valve prolapse (MVP) as one of the most common valve diseases worldwide. It can help us to better understand pathophysiology of this common disease. Materials ...

Segmentation of the Left Atrial Appendage in the Echocardiographic Images of the Heart Using a Deep Neural Network

Introduction: Cardiovascular diseases are one of the leading causes of mortality in today’s industrial world. Occlusion of left atrial appendage (LAA) using the manufactured devices is a growing trend. The objective of this study was to develop a computer-aided diagnosis system for the identification of LAA in echocardiographic images. Method: The data used in this descriptive analytical study ...
