Abstract

Objective:
Cardiovascular risk prediction is deemed fundamental and the assessment of organ damage is emerging as a potentially ‘downstream’ picture of individual risk. Our aim was to assess the feasibility and value of prediction of coronaropathy [coronary artery disease (CAD)] of integrated cardiovascular ultrasound examination.

Methods:
This multicenter study involved eight cardiology centers that enrolled 457 consecutive patients. Blood pressures, carotid intima–media thickness (cIMT), carotid pulse wave velocity (cPWV), semiquantitative score of cardiac calcifications, global myocardial longitudinal strain (GLS), and rest Doppler flow velocity on the left anterior descending (LAD) coronary artery were measured. After coronary angiography, patients were divided in CAD, n = 273, at least one coronary stenosis higher than 50%, and no CAD, n = 184.

Results:
CAD were older (65.9 ± 10.7 versus 63.1 ± 11.2 years, mean ± standard deviation, P = 0.01), and had higher blood pressure (137.0 ± 18.8/77.5 ± 11.1 versus 130.2 ± 17.4/75.1 ± 9.7 mmHg, P < 0.02), cIMT (791.4 ± 165.5 versus 712.0 ± 141.5 mcm, P < 0.0001), cPWV (median: 9 versus 8.1 m/s, P < 0.01), score of calcium (median, 2 versus 1, P < 0.0001), LAD velocity (median, 38 versus 36, P < 0.07), and lower GLS (−17.6 ± 4.3 versus −19.3 ± 5.1, P < 0.05) than no CAD. Score of calcium was feasible in the totality of patients, cIMT in 97%, cPWV in 86%, GLS in 88%, and LAD in 84%. A combination of at least three variables was measurable in 80% of the patients. All ultrasound parameters significantly predicted CAD. However, in a stepwise logistic regression, the only combined predictors of obstructive CAD were score of calcium, cIMT, and LAD velocity.

Conclusion:
In Echo-Lab, Rome, Italy, the integrated cardiovascular ultrasound study is feasible in a high percentage of patients. The combination of three parameters, that is, score of calcium, cIMT, and LAD velocity, has incremental predictive value for obstructive CAD.
