- Abstract
- During left ventricular opacification (LVO), myocardial contrast uptake (MCU) is frequently observed, but its clinical implication is uncertain. We aimed to investigate the diagnostic performance of MCU and its prognostic value in known or suspected coronary artery disease (CAD). Contrast echocardiography was retrospectively analyzed in 457 patients who had previous coronary angiography <12 mo before LVO. MCU was classified into replacement or interstitial patterns. Subendocardial patterns were further inspected. Events were defined as a primary composite of the occurrence of acute coronary syndrome, heart failure hospitalization, sustained ventricular tachycardia and all-cause mortality. MCU had an 87.6% sensitivity, 75.5% specificity, 73.0% positive predictive value and 87.7% negative predictive value in detecting CAD. After a median follow-up of 17.3 mo, 52 events occurred. Replacement, interstitial and subendocardial MCU patterns were associated with events. In conclusion, the presence of MCU was useful in identifying CAD and provided incremental prognostic value for clinical outcomes.
