Feb 24 2015 Introduction. Computed tomographic CT coronary angiography is recommended as an initial investigation to assess symptomatic patients with low to intermediate risk of coronary artery disease .In its current form however CT coronary angiography has limited specificity in determining the functional significance of coronary stenoses 2 3 .For this reason patients
Dec 04 2018 Coronary artery calcium scoring is useful in diagnosing subclinical coronary artery disease and has emerged as a means of risk stratification by direct measurement of disease. Many providers are using it and its relatively low cost and ease of performance have contributed to its widespread use.

Feb 27 2020 Calcium Scoring. Coronary artery calcium CAC scoring is a noninvasive test that has been reported to detect the presence of subclinical coronary artery disease CAD by measuring the location and extent of calcium in the coronary arteries.
Results of direct coronary revascularization with 511 grafts in 213 patients from 1971 to 1974 are reviewed. To improve an early saphenous vein graft SVG patency of 84 per cent in the first 85 patients we have used internal mammary artery grafts IMAG when possible since January 1973. In 1973

Mar 29 2018 The advent of coronary angiography in the 1960s allowed for the risk stratification of patients with stable angina. Patients with unprotected
Oct 01 2013 Introduction. Coronary artery calcium CAC scoring is a well validated clinical tool for the early detection of coronary artery atherosclerosis and provides valuable prognostic information 1 2 .In symptomatic patients the absence of measurable CAC has a high negative predictive value for the exclusion of obstructive anatomic coronary artery disease CAD 3 4 .
Nov 14 2015 Insulin resistance is a major component of metabolic syndrome type 2 Diabetes Mellitus T2DM and coronary artery disease CAD . Although important in T2DM its role as a predictor of CAD in non diabetic patients is less studied. In the present study we aimed to evaluate the association of HOMA IR with significant CAD determined by coronary
A risk scoring system was created based on these features and retrospectively applied to our historical series of 140 consecutive patients 52 females mean age 60.1±19.3 years mean follow up 60±23 months . Origin from the pulmonary artery intramural course intramyocardial course coronary fistula with a significant pulmonary to
May 10 2003 Pathophysiology. Coronary artery disease is almost always due to atheromatous narrowing and subsequent occlusion of the vessel. Early atheroma from the Greek athera porridge and oma lump is present from young adulthood onwards. A mature plaque is composed of two constituents each associated with a particular cell population.
Dec 01 2011 Background. Coronary artery disease CAD is the leading killer in the U.S. Patients with severe CAD and ischemia have worse prognosis. Therefore expansion of biomarker research to identify at risk individuals and explain the complex biology between cardiovascular growth factors and atherosclerosis is needed.
Atherosclerotic coronary artery disease CAD affects the coronary arteries which deliver blood to the myocardium. CAD symptoms include stable
Angiography is inaccurate in assessing the functional significance of a coronary stenosis when compared with the FFR not only in the 50 to 70 category but also in the 70 to 90 angiographic severity category. OBJECTIVES The purpose of this study was to investigate the relationship between angiographic and functional severity of coronary artery stenoses in
Sep 01 2016 Coronary artery disease CAD is the leading cause of death . To evaluate CAD invasive coronary angiography CAG has been regarded as the reference standard . However substantial discrepancies between angiographic anatomic findings and functional severity of stenosis have been noted 2 3 .
he therapeutic goals of coronary artery grafting bypass surgery CABG for patients with stable ischemic heart disease are to prolong survival and improve health status including symptoms function and quality of life.1 In patients with advanced coronary artery disease completeness of revascularization is in

Apr 02 2008 Coronary artery disease was defined as a 50 or greater lumen narrowing of a major epicardial artery or its branches. A left main stenosis of 50 or greater was regarded as equivalent to 2 vessel disease. Blood samples were collected during admission before angiographic procedure.
