Values are mean ± SD or n (%); High-PA indicates people who PA rate of decrease is small at Emergency Declaration on Changes. Low-PA indicates people who PA rate of decrease is big at Emergency Declaration on Changes; SBP: Systolic Blood Pressure; ARB: Angiotensin II Receptor Antagonists; ACE: Angiotensin Converting Receptor; CCB: Calcium Channel Blocker; Rt: Right; Lt: Left; m: meters; p<0.05 High-PA vs. Low-PA.
