Relation between diastolic left ventricular function and myocardial blood volume during adenosine-induced coronary hyperemia.

abstract：BACKGROUND:Multiple genetic loci are associated with clinical cardiovascular (CV) disease and individual CV risk factors. Individuals with ideal levels of all major CV risk factors have very low risk for CV disease morbidity or mortality. Ideal levels of risk factors can be attained by lifestyle modifications; however,...
