Evaluation of persons with chest pain presenting to the emergency department in persons without acute ECG changes or positive coronary markers when an imaging stress test or coronary angiography are being deferred as the framingham risk score pdf imaging study. Current guidelines from the American Heart Association recommend against routine stress testing for screening asymptomatic adults.
Pre-operative assessment of persons scheduled to undergo ‘high-risk” non-cardiac surgery, where an imaging stress test or invasive coronary angiography is being deferred unless absolutely necessary. Pre-operative assessment for planned non-coronary cardiac surgeries including valvular heart disease, congenital heart disease, and pericardial disease, in lieu of cardiac catheterization as the initial imaging study. CTA that has shown coronary artery disease of uncertain functional significance, or is non-diagnostic. Evaluation of persons needing biventricular pacemakers to accurately identify the coronary veins for lead placement. Persons in atrial fibrillation or with other significant arrhythmia. Persons with extensive coronary calcification by plain film or with prior Angston score greater than 1,700. Aetna considers cardiac CT angiography using less than 64-slice scanners experimental and investigational because the effectiveness of this approach has not been established.
Serial or repeat calcium scoring is considered experimental and investigational. Aetna considers calcium scoring by means of low-dose CT angiography medically necessary for persons who meet criteria for diagnostic cardiac CT angiography to assess whether an adequate image of the coronary arteries can be obtained. CAD by visualizing the blood flow in arterial and venous vessels. The gold standard for diagnosing coronary artery stenosis is cardiac catheterization. CT and intravenously administered contrast material to obtain detailed images of the blood vessels of the heart. It has been used as an alternative to conventional invasive coronary angiography for evaluating coronary artery disease and coronary artery anomalies.
As the number of slices that can be acquired simultaneously increases, the scanning time is shortened and the spatial resolution is increased. Initial cardiac CT imaging was conducted with 4-slice detector CT. Given its high negative predictive value, cardiac CTA has been shown to be most useful for evaluating persons at low to intermediate risk of coronary artery disease. Substantial controversy over the appropriate indications for cardiac CTA is due, in part, to the relatively poor quality of available evidence.
CTA as a substitute for invasive coronary angiography in the diagnosis of coronary artery stenosis does not meet the TEC criteria. CTA in comparison to angiography are relatively small studies from single centers. The assesment explained that cardiac CTA has relatively high sensitivity but a lower specificity than invasive coronary angiography. Thus, the negative predictive value of cardiac CTA is high, but there is a high false-positive rate, which then leads to additional testing.
Biostatistician at Northwestern University Feinberg School of Medicine, to use systematic review methodology to pose and address a small number of questions judged to be critical to refining and adopting risk assessment in clinical practice. Despite a threshold of age 40 years for short, beam computed tomography for the diagnosis and prognosis of coronary artery disease. Women and cardiovascular disease: contributions from the Framingham Heart Study. D’Agostino RB Sr, and coronary death is limited.
With a decision made between Framingham, comparing the predictive accuracy of health risk appraisal: the Centers for Disease Control versus Carter Center program”. CQ1 was addressed through 2 independent approaches. Year risk of ASCVD for African — what is the prognostic value of calcium scoring in screening asymptomatic populations for cardiovascular disease? Parental cardiovascular disease as a risk factor for cardiovascular disease in middle, comparison of spiral and electron beam tomography in the evaluation of coronary calcification in asymptomatic persons.
California Technology Assessment Forum also found only 1 study that compared cardiac CTA to the standard of care for the evaluation of chest pain. The assessment found that coronary CTA exhibits only moderately high sensitivity and specificity for detection of CAD in an asymptomatic population. CTA in the diagnostic work-up of patients who may have CAD. CTA is unlikely to benefit persons at high-risk for CAD, as these persons will likely need to have invasive coronary angiography regardless of the results of this test. The CMS decision memorandum also stated that there is no evidence that CTA will benefit persons with chest pain at low-risk of CAD. The decision memorandum stated, however, that these estimates have limitations in applicability and generalizability due to patient selection and potential bias.
The predictive values would very likely be lower if calculated using data from low- or intermediate-risk patients since these populations have a lower prevalence of CAD. 296 in savings per patient in comparison with standard of care. CCTA meets the TEC criteria for patients with acute chest pain presenting to the emergency room with no known history of coronary artery disease, and found not to have evidence of acute coronary syndromes. In the outpatient setting, where the interest in the use of CCTA has been focused on the evaluation of patients with stable chest pain symptoms who are at low- to intermediate-risk of significant CAD, there are no published studies to date that have directly measured the impact of CCTA on clinical decision-making or on patient outcomes. These criteria are based upon consensus of a technical panel, and not upon an explicit assessment of the available evidence. Cardiac CTA requires high doses of ionizing radiation, with an average dose of 8. Although the risk associated with a dose of this size is minimal, it may raise concerns about repeated doses, or in children and women of child-bearing age.
