background: paraoxonase-1(pon1), a high-density lipoprotein (hdl) associated enzyme, is believed to contribute in the pathogenesis of coronary artery disease (cad). the aim of this study was to evaluate the association of pon1 promoter c (-107)t polymorphism with the extent of coronary artery stenosis in iranian patients. methods : the rflp analysis for determination of the c(-107)t genotype d...
Abstract Background: Coronary artery disease, (CAD) is an important risk for morbidity and mortality. Because of controversial reports about relation between high-sensitivity C-reactive protein (hs-CRP) level and the severity of coronary artery stenosis, this study was done in Taleghani Hospital. Methods: In this case-control study 85 patients with CAD undergoing coronary angiography were ...
Background & Aim: Serum paraoxonase (PON1) is an HDL (high density lipoprotein) associated esterase that prevents the oxidation of LDL (low density lipoprotein). A common polymorphism in coding region of the paraoxonase gene involving a Gln (Q) to Arg (R) interchange at position 192 has been demonstrated to affect PON1 activity. It has been shown that R alloenzyme is less efficient at prevent...
The aim of this study is to investigate the effects of non-Newtonian blood rheology models on the wall shear stress (WSS) distribution in a cohort of patients-specific coronary arteries. Twenty patients with diseased left anterior descending (LAD) coronary arteries (with varying degrees of stenosis severity from mild to severe) who underwent angiography and in-vivo pressure measurements were se...
purpose: to evaluate the effect of stenosis nature on success of silicone intubation for nasosolacrimal duct stenosis (nlds) in adults (patent nasolacrimal duct with resistance to positive-pressure irrigation) methods: an interventional case series of consecutive monocanalicular and bicanalicular silicone intubation for nasolacrimal duct stenosis in adults were reviewed. the severity of the ste...
Background: Epidemiological studies have suggested an association between higher body iron stores and coronary artery disease. It is believed that inflammation and oxidation are important mechanisms involved in the complex pathological process of atherogenesis. Free radical production is catalyzed and accelerated in the presence of iron. The determination of plasma ferritin levels is a convenie...
conclusions our findings revealed that the severity of coronary artery stenosis is common in diabetic patients compared to nondiabetics. early diagnosis and treatment of cad in diabetic patients is recommended. results based on data found in our study, 93.8% of diabetic and 83.4% of nondiabetic patients were shown to suffer coronary artery stenosis. severe involvement (grade 3vd) of coronary ar...
background: early clinical and retrospective angiographic evaluations indicated that in patients with acute myocardial infarction (mi), vulnerable plaques most often represented a mild luminal stenosis. more recent studies drawing upon prospective angiograms, however, have demonstrated that in majority of patients with acute mi, the underlying stenosis is significant. methods: twenty-eight pa...
Background & Aims: The clinical value of T wave inversion (TWI) in the lead aVL in diagnosing coronary artery disease (CAD) remains unclear. Hence, we aim to evaluate the association between TWI in the aVL lead and the severity and location of coronary artery stenosis in elective coronary angiography. Material and Method: Electrocardiograms (ECGs) of 167 consecutive patients undergoing electiv...
