Table 4.

Hemodynamic variables of sham-operated rats and rats with left ventricle dysfunction

Groups LVEDP (mmHg) LVSP (mmHg) +dP/dtmax (mmHg/s) −dP/dtmax (mmHg/s)
Sed-Sham 4.6 ± 1 120.1 ± 13.5 6113 ± 1389 −4175 ± 932
RMT-Sham 5.5 ± 1.6 122 ± 15.1 6644 ± 982 −4247 ± 472
Sed-HF 21.9 ± 5.2* 93.1 ± 8.5* 4071 ± 678† −2602 ± 432†
RMT-HF 14.5 ± 6.7‡ 113.4 ± 11 5237 ± 1630‡ −2921 ± 852‡

Values are means ± SD; n = 8 for all groups. LVEDP, LV end-diastolic pressure; LVSP, LV systolic pressure; +dP/dtmax, LV maximum change in pressure over time; and −dP/dtmax, LV minimum change in pressure over time.
