Early Detection of Myocardial Infarction in Low-Quality Echocardiography

چکیده
Myocardial infarction (MI), or commonly known as heart attack, is a life-threatening health problem worldwide from which 32.4 million people suffer each year. Early diagnosis and treatment of MI are crucial to prevent further tissue damages death. The earliest most reliable sign ischemia regional wall motion abnormality (RWMA) the affected part ventricular muscle. Echocardiography can easily, inexpensively, non-invasively exhibit RWMA. In this article, we introduce three-phase approach for early detection in low-quality echocardiography: 1) segmentation entire left ventricle (LV) using state-of-the-art deep learning model, 2) analysis segmented LV by feature engineering, 3) detection. main contributions study highly accurate echocardiography, pseudo labeling ground-truth formation unannotated wall, first public echocardiographic dataset (HMC-QU)* Furthermore, outputs proposed significantly help cardiologists better assessment characteristics. has achieved 95.72% sensitivity 99.58% specificity segmentation, 85.97% sensitivity, 74.03% specificity, 86.85% precision on HMC-QU dataset. *The benchmark publicly shared at repository https://www.kaggle.com/aysendegerli/hmcqu-dataset

Early prediction of improvement in ejection fraction after acute myocardial infarction using low dose dobutamine echocardiography.
OBJECTIVE To evaluate the relation between changes in ejection fraction during the first three months after acute myocardial infarction and myocardial viability. PATIENTS Myocardial viability was assessed using low dose dobutamine echocardiography in 107 patients at mean (SD) 3 (1) days after acute myocardial infarction. Cross sectional echocardiography was repeated three months later. Left v...

The contrast agents used in ultrasound are approved for several clinical situations. New echocardiographic techniques, such as harmonic imaging and power pulse inversion imaging, can improve the visualization of microbubbles. In this article we discuss the early development of contrast echocardiography, new technologies that help improve image acquisition and its practical role in the assessmen...
متن کاملDetection and clinical usefulness of a biphasic response during exercise echocardiography early after myocardial infarction.
OBJECTIVE The aim of this study was to determine the accuracy of exercise echocardiography (EE) for detecting infarct-related artery (IRA) stenosis and predicting functional recovery early after acute myocardial infarction (AMI). BACKGROUND Dobutamine stress echocardiography is widely used for identifying jeopardized myocardium. The clinical usefulness of a biphasic response detected during E...
متن کاملPrognostic value of myocardial viability detected by myocardial contrast echocardiography early after acute myocardial infarction.
OBJECTIVES This study sought to determine whether residual myocardial viability determined by myocardial contrast echocardiography (MCE) after acute myocardial infarction (AMI) can predict hard cardiac events. BACKGROUND Myocardial viability detected by MCE has been shown to predict recovery of left ventricular (LV) function in patients with AMI. However, to date no study has shown its value ...
