Prediction of coronary events with electron beam computed tomography

Abstract

In asymptomatic adults, EBCT of the coronary arteries predicts coronary death and nonfatal MI and the need for revascularization procedures.

Coronary artery calcification and emphysema

“…CAC is also associated with an increased risk of future cardiovascular disease (CVD) in middle-aged populations (1)(2)(3)(4).…”

“…Therefore, it is necessary that other tests be used for a better stratification of the risks for coronary events. Data from the literature have shown that the presence of coronary artery calcification is associated with a greater risk for coronary events [11][12][13][14] , and its absence is associated with an almost-zero risk for coronary events in studies of 3-to-5 year follow-up 25 . Coronary artery calcium scores have their major usefulness in stratifying the risk for clinical events.…”

“…Ultrafast computed tomography is a noninvasive and very sensitive method to detect calcification in coronary arteries 7 . Evidence exists that the presence of coronary artery calcification on ultrafast computed tomography may be a risk marker of clinical events in coronary artery disease, independent of the risk factors for atherosclerosis [11][12][13][14] . Up to now, coronary artery calcium scores in the Brazilian population have not been reported.…”

“…These include exercise electrocardiogram testing (626,627,655), ambulatory electrocardiogram monitoring (656,657), measurement of left ventricular ejection fraction (658,659), magnetic resonance imaging (660), exercise or dipyridamole single-photon emission computed tomography (SPECT) (658,661), positron emission tomography (PET) (662), electron beam computed tomography (663)(664)(665)(666)(667)(668) and thallium/sestamibi scintigraphy (with exercise or dipyridamole) (669-674) echocardiography (with exercise or dobutamine) (675,676). Few studies have assessed exercise electrocardiogram testing in patients with ESRD.…”

“…Recently, results of electron beam computed tomography have been shown to correlate with both angiographic coronary artery disease and IHD events (663)(664)(665)(666)(667)(668). However, a study of 1196 high-risk patients found no difference between electron beam computed tomography and traditional risk-factor assessment in predicting coronary events (681).…”
