OBJECTIVES The authors tested the hypothesis that exercise treadmill testing (ETT)-induced ST-segment elevation (STE) in electrocardiographic lead aVR is an important indicator of significant left main coronary artery (LMCA) or ostial left anterior descending coronary artery (LAD) stenosis. BACKGROUND Although STE in lead aVR is an indicator of LMCA or very proximal LAD occlusion in acute cor...
A single left coronary artery with right coronary artery arising from either left main stem (LMS) or left anterior descending artery (LAD) or circumflex artery (Cx) is an extremely rare coronary anomaly. This is the first report of separate origins of proximal and distal RCA from LAD and circumflex arteries respectively in a patient with a single left coronary artery. This 57 year old patient p...
چکیده مقدمه: آترواسکلروزیس یکی از علل عمده مرگ و میر در کشورهای پیشرفته است. در گذشته، محققین زیادی ثابت نموده اند که فاکتورهایی از قبیل سیگار کشیدن، میزان کلسترول خون و فشار خون نقش مهمی در پاتوژنز بیماریهای قلبی عروقی دارند. تحقیقات برای اتیولوژی بیماری به این ایده منجر گردیده است که ممکن است عناصر کمیاب در شروع و یا پیشرفت بیماری آترواسکلروزیس نقش داشته باشند. ثابت شده است که عناصر کمیاب نقش...
OBJECTIVE The present study was performed to compare coronary flow reserve by transesophageal Doppler echocardiography and intracoronary Doppler flow wire measurements in patients with LAD disease. METHODS 17 patients with various degree of LAD stenosis were studied. Intracoronary LAD Doppler measurements were performed at baseline and after intracoronary injection of 18 micrograms adenosine....
rigination of the first major septal perforator branch from a site other than the left anterior descending coronary artery (LAD) is a relatively rare and benign congenital variation. 1 Coronary angiography reveals anomalous vessels originating directly from the aorta and from the proximal portion of the right coronary artery as collateral circulation to the LAD, particularly in patients with pr...
INTRODUCTION Neutrophil to lymphocyte ratio (NLR) was revaled to have a close relation with atherosclerotic cardiovascular disease. The relationship between NLR and culprit plaque localization has never been studied. AIM OF THE STUDY To evaluate the association between NLR and unstable plaque localization of left anterior descending artery (LAD) in anterior miyocardial infarction patients. ...
OBJECTIVES Coronary endarterectomy has been shown to be an effective adjunctive technique of revascularization for diffuse coronary artery disease. A long arteriotomy and reconstruction of the left anterior descending artery (LAD) are occasionally required for complete extraction of the atherosclerotic plaque. The aim of this study was to examine early and late results of this technique and com...
Leukocyte adhesion deficiency type I (LAD-I), a disease syndrome associated with frequent microbial infections, is caused by mutations on the CD18 subunit of β₂ integrins. LAD-I is invariably associated with severe periodontal bone loss, which historically has been attributed to the lack of neutrophil surveillance of the periodontal infection. We provide an alternative mechanism by showing that...
OBJECTIVES We sought to determine the safety and efficacy of using multiple overlapping drug-eluting stents (DES) in patients with diffuse left anterior descending coronary artery (LAD) disease. BACKGROUND Diffuse LAD disease represents a therapeutic challenge. Results after coronary artery bypass surgery are suboptimal, whereas the use of bare metal stents is limited by high rates of resteno...
periodontal involvement in leukocyte adhesion deficiency: review of the literature and a case report
objective: leukocyte adhesion deficiency(lad) is a scarce, autosomal recessive inherited disorder . lad-i which is the most common type occurs due to mutations on the cd18 gene. this mutation leads to absence or severe reduction of leukocyte cell surface expression of ß2 integrin molecules which are necessary for the adhesion of the leukocytes to the endothelial cells, transendothelial migratio...
