Hemodynamic parameters recorded from young and old swine used in the microarray and electrophysiological analysis.

n = 3–5 pigs per group.*Designates difference between age groups (unpaired t-test);¥designates a change produced by autonomic blockade within a group (paired t-test).• HR = heart rate.• mAP = mean arterial pressure.• SVI = stroke volume indexed to body size.• CI = cardiac output indexed to body size.• SVRI = systemic vascular resistance indexed to body size.• mPAP = mean pulmonary arterial pressure.• PVRI = pulmonary vascular resistance indexed to body size.• LVPmax = maximal left ventricular pressure.• LVEDP = left ventricular end-diastolic pressure.
