Myocardial perfusion and coronary microvessel reactivity. A, Myocardial perfusion at rest and with demand pacing. No difference was seen in myocardial perfusion at rest or during demand pacing at 160 beats/min. B, Microvessel reactivity. No difference was seen in microvessel reactivity to endothelium-dependent (adenosine diphosphate [ADP]) or endothelium-independent (sodium nitroprusside [SNP]) vasodilators in oral hypercaloric/hypercholesterolemic diet (OHC) and oral hypercaloric/hypercholesterolemic diet plus 1.5 mg/kg atorvastatin daily (OHCS) groups. C, Baseline microvessel diameter and percentage of preconstriction. No difference was seen in baseline diameter or percentage of preconstriction in ADP- or SNP-treated microvessels.
