Background:: Coronary artery disease (CAD) is commonly cited as a mechanism underlying diastolic dysfunction. However, the association of CAD without ischemia and left ventricular (LV) diastolic dysfunction has not been convincingly demonstrated in asymptomatic patients. The objective of this study was to determine if such a relation exists using coronary artery calcium score (CACS) as a surrogate for coronary atherosclerosis burden.
.
Conclusions:: In asymptomatic patients with normal LV ejection fraction and negative cardiac stress test results, CACS does not correlate with LV diastolic function as defined by established Doppler echocardiographic criteria. In the absence of ischemia, postinfarction LV remodeling, or previous coronary artery bypass surgery, CAD does not appear be a cause of LV diastolic dysfunction in asymptomatic patients.
