- The number of experiments was 8, 4 and 4 for the C, HF- and HF + groups. The heart rate, pressures (systolic, diastolic and left ventricular developed pressures), dP/dt max and dP/dt min were expressed in beats/min, mmHg and mmHg/s. C: control; HF-: high fat-fed rats without weight gain; HF+: high fat-fed rats with weight gain; HR: heart rate; SP: systolic pressure; DP: diastolic pressure; LVDP: left ventricular developed pressure; dP/dt max: maximum rate of pressure change; dP/dt min: maximum rate of pressure change; a, b: two means located on a same line without a common letter are significantly different.
