Dobutamine stress cardiovascular magnetic resonance at 3 Tesla

Table 2 Hemodynamic data.

Left ventricular function (rest)
LVEF, %	56.4 ± 6.8
LVEDV, ml	134.2 ± 31.7
LVESV, ml	60.9 ± 20.9
Heart rate, bpm
At rest	63.3 ± 9.2
Maximum stress	123.1 ± 20.9
Systolic blood pressure, mmHg
At rest	133.9 ± 20.7
Maximum stress	131.7 ± 29.2
Diastolic blood pressure, mmHg
At rest	77.0 ± 11.9
Maximum stress	72.9 ± 15.6
Heart rate-pressure product, bpm × mmHg
At rest	8505.2 ± 1956.9
Maximum stress	9709.6 ± 2541.7

Values are expressed as mean ± standard deviation. LVEF = left ventricular ejection fraction; LVEDV = left ventricular end-diastolic volume; LVESV = left ventricular end-systolic volume; bpm = beats per minute. Heart rate – pressure product is heart rate times systolic blood pressure.
