Table 3. Comparison of myocardial blood flow between CMD and normal patients.

Variable	CMD patients (n=50)	Control patients (n=52)	t	P
LAD rMBF (mL/g/min)	0.88±0.14	0.81±0.17	1.569	0.123
LAD sMBF (mL/g/min)	1.32±0.33	2.47±0.74	−7.192	<0.001
LCX rMBF (mL/g/min)	0.80±0.15	0.83±0.15	−0.677	0.502
LCX sMBF (mL/g/min)	1.12±0.43	2.35±0.66	−7.882	<0.001
RCA rMBF (mL/g/min)	0.84±0.16	0.80±0.19	−0.736	0.465
RCA sMBF (mL/g/min)	1.41±0.47	2.66±0.96	−5.876	<0.001

Values are given as mean ± SD. CMD, coronary microvascular dysfunction; MBF, myocardial blood flow; rMBF, rest MBF; sMBF, stress MBF; LAD, left anterior descending; LCX, left circumflex; RCA, right coronary artery.
