Relationship between Neutrophil-to-lymphocyte Ratio and the Severity of Coronary Artery Disease in Patients Undergoing Cardiac Catheterization
Introduction: Neutrophil-to-lymphocyte ratio (NLR) is considered as an independent predictor of long-term prognosis in the individual patients with coronary artery disease (CAD). This study sought to assess the relationship between NLR and CAD severity in Iranian patients undergoing cardiac catheterization.Material and Methods: This prospective study was conducted on 500 patients with acute cor...
متن کاملPhysiological severity of coronary artery stenosis.
THREE FUNDAMENTAL ADVANCES in our knowledge underlie the rapidly evolving long-term treatment of coronary artery disease (CAD), summarized briefly here for perspective on the paper by Marques and colleagues (17) in this issue of American Journal of Physiology-Heart and Circulatory Physiology, on quantifying severity of coronary artery stenoses by their pressure-flow velocity relation. The first...
متن کاملValidation Studies at Cardiac Catheterization
In this study, we explored the use of continuous wave Doppler-echocardiography guided by color Doppler flow-mapping as a method for noninvasively calculating the rate of pressure rise (RPR) in the left ventricle. Continuous wave Doppler determination of the velocities in mitral regurgitant jets allows calculation of instantaneous pressure gradients between the left ventricle and the left atrium...
متن کاملAssessment of intermediate severity coronary lesions in the catheterization laboratory.
The management of intermediate coronary lesions, defined by a diameter stenosis of 40% to 70%, continues to be a therapeutic dilemma for cardiologists. The 2-dimensional representation of the arterial lesion provided by angiography is limited in distinguishing intermediate lesions that require stenting from those that simply need appropriate medical therapy. In the era of drug-eluting stents, s...
متن کاملValidation of the severity index by cardiac catheterization and Doppler echocardiography in patients with aortic sclerosis and stenosis
The severity index is a new echocardiographic measure that is thought to be an accurate indicator of aortic leaflet pathology in patients with AS. However, it has not been validated against cardiac catheterization or Doppler echocardiographic measures of AS severity nor has it been applied to patients with aortic sclerosis. The purposes of this study were to compare the severity index to invasi...
