Carotid Ultrasound for Risk Clarification in Young to Middle-Aged Adults Undergoing Elective Coronary Angiography*

摘要: Background An important aspect of risk prediction is the apparent difference between calculated and true risk. Current predictor models are not sensitive enough to identify many subjects at for future events or prevent overuse expensive tests. The aim this study was determine usefulness carotid ultrasound stratification in undergoing elective coronary angiography. Methods A total 253 individuals (men ≤55 years age women ≤65 age) who were scheduled angiography underwent ultrasonography. Noncoronary atherosclerosis defined based on a maximal intima-media thickness ≥1.0 mm presence focal plaque. Results Of subjects, 236 completed all mean 51 ± 8 years, 58% 42% men. Severe angiographic disease (≥50%) present 72 subjects. Carotid 141 Use Framingham score classified 172 as low diagnosed 57% low-risk group compared with 70% high-risk (P = .122). associated severe (OR 2.2, CI 1.2 4.0). Conclusion determined by had high negative predictive value stress test results risk-stratified Noninvasive imaging ultrasonography noncoronary may be good adjunct clinical premature heart disease.
