Abstract

Atrioventricular plane displacement is a well-accepted method for assessment of left ventricular systolic function. We explored the ability of atrioventricular plane displacement to predict inhospital outcome in patients with acute ST-elevation myocardial infarction. Ninety three patients with acute ST-elevation myocardial infarction were prospectively included. Each patient underwent trans-thoracic echocardiography for measurement of the ejection fraction by the Simpson's method. Atrioventricular plane displacement was measured from the apical views, assessed in four different regions, namely, the septal, lateral, anterior and inferior ones, and the mean value was calculated. We used a cutoff value to classify patients into a group with atrioventricular plane displacement <10 mm and another with atrioventricular plane displacement > or=10 mm. Similarly, patients were classified into those with ejection fraction <40% and others with ejection fraction a 40%. All patients were followed-up during their in-hospital stay for the occurrence of major adverse cardiac events, namely, death, heart failure, complex ventricular arrhythmias, post-infarction angina, or mechanical complications. During the follow-up period (3 +/- 1.5 days), m...Continue Reading

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
