Values at baseline and during adenosine infusion

	ICDGW (Invasive)			TTD (Noninvasive)
	Baseline	Adenosine	P Value	Baseline	Adenosine	P Value
SBP, mmHg	115 ± 8	111 ± 9	NS	119 ± 6	121 ± 8	NS
DBP, mmHg	66 ± 6	64 ± 7	NS	60 ± 5	60 ± 6	NS
HR, beats/min	69 ± 5	77 ± 6*	<0.05	65 ± 7	74 ± 6*	<0.05
PDV, cm/s	54 ± 7	85 ± 9*	<0.05	19 ± 3	31 ± 6*	<0.05

Values (means ± SE) were obtained from patients who underwent LAD percutaneous coronary intervention. The hemodynamic data were obtained during baseline and during intravenous infusion of adenosine (0.14 mg·kg⁻¹·min⁻¹ for 6 min) during the 2 study periods. The invasive studies were performed using an intracoronary Doppler guidewire (ICDGW) placed in the mid-LAD (distal to stent placement). The noninvasive data were obtained with transthoracic duplex ultrasound (TTD) of the distal LAD. Note, HR and peak diastolic velocity (PDV) both increased during adenosine infusion.

^*Significantly different (P < 0.05) from the corresponding baseline values. NS, not significant.
