Coronary Reactivity Testing Results

Variables	Total Cases N=41	With CMD N=34	No CMD N=7	Controls N=20	p- Value*
LV End Diastolic Pressure	15 ± 4.5	15 ± 4.5	14 ± 6.1	n/a	0.62
Coronary Flow Reserve	2.8 ± 0.8	2.7 ± 0.9	3.1 ± 0.5	n/a	0.37
Δ Coronary Blood Flow	53 ± 92	29 ± 72	168 ± 94	n/a	<0.0001

Values expressed as mean ± SD.

CMD= coronary microvascular dysfunction defined by abnormal coronary flow reserve to adenosine and/or abnormal coronary blood flow change to acetylcholine, LV= left ventricular, Δ = change in coronary blood flow compared to baseline
