this study was conducted to determine whether precordial st segment depression in admission electrocardiogram (ecg) in patients with acute phase inferior myocardial infarction (mi) eligible for thrombolytic therapy and subsequent angiographic evaluation, influences the incidence of left anterior descending artery (lad) disease. 31 consecutively admitted patients were entered in our study. 20 pa...
In the presence of severe stenosis, coronary artery flow may be reduced at rest. Recent advances in echocardiography have made non-invasive sampling of velocities in the left anterior descending coronary artery (LAD) possible. The aim of our study was to evaluate feasibility and capability of transthoracic Doppler to detect severe stenosis of the LAD. The study population consisted of 42 subjec...
BACKGROUND Single-vessel coronary artery disease is usually treated with PTCA; however, this approach when applied to the left anterior descending coronary artery (LAD) is hampered by high restenosis rates, often approaching 50%. Coronary stenting (STENT) and left internal mammary artery bypass grafting of the LAD (LIMA-LAD) are other options that have been successfully used for single-vessel L...
INTRODUCTION We hypothesized that coronary flow reserve (CFR) in the left anterior descending artery (LAD) can be effectively measured during an accelerated dipyridamole-atropine stress echocardiography (DASE) protocol to improve the diagnostic performance of the test. MATERIAL AND METHODS In 64 patients with suspected or known coronary artery disease scheduled for coronary angiography DASE w...
OBJECTIVE Early-onset Alzheimer's disease (EAD) shows distinct features from late-onset Alzheimer's disease (LAD). To explore the characteristics of EAD, clinical, neuropsychological, and functional imaging studies have been conducted. However, differences between EAD and LAD are not clear, especially in terms of brain connectivity and networks. In this study, we investigated the differences in...
Normal values for left anterior descending coronary artery (LAD) flow velocity were assessed from a large number of normal children. In 303 healthy children, LAD peak flow velocity was measured by Doppler echocardiography. LAD peak flow velocities were calculated considering the angle between the Doppler beam and the coronary flow direction. The flow signals of LAD were recorded in 95% (288/303...
Leukocyte Adhesion Deficiency I (LAD-I) is a primary immunodeficiency caused by single gene mutations in the CD18 subunit of β2 integrins which result in defective transmigration of neutrophils into the tissues. Affected patients suffer from recurrent life threatening infections and severe oral disease (periodontitis). Microbial communities in the local environment (subgingival plaque) are thou...
Measurements of mean left ventricular (LV) and regional myocardial blood flow rates were made at rest in 161 patients with 133Xe and a multiplecrystal scintillation camera. Myocardial perfusion rates were correlated with assessments of the degree of coronary artery disease made from the arteriograms obtained during the same studies. In patients with normal coronary arteries without heart failur...
