Values are means ± SE; n = 16. Data are from minute 2 of handgrip (HG) and posthandgrip ischemia (PHGI). HR, heart rate; SBP, systolic blood pressure in mmHg; DBP, diastolic blood pressure; MAP, mean arterial pressure; MSNA/100, muscle sympathetic nerve activity (burst incidence); HFrEF, heart failure with reduced ejection fraction.
