The blood pressure (BP) response to supine rest for one hour and to an isometric handgrip exercise (3 min, 30%, of maximum) was investigated in 18 healthy normotensive men (N) (casual BP 117 ± 6 / 73 ±5 mmHg, 39± 3 years old) (mean ± SD) and 50 men with essential hypertension (H) (162 ± 13 / 105 ±9 mmHg, 41 ± 4 years old). Casual BP was decreased by rest to resting BP (113 ± 7/70 ±7 in N and 140 ± 15/ 93 ± 11 mmHg in H). H was divided into 3 groups of H-1 (resting BP of 124 ± 7 / 80 ± 4 mmHg), H-2 (137 ± 9 / 92 ± 4) and H-3 ( 154 ± 10 / 104 ± 4). The decreases in BP with rest were significantly greater in Groups H-1 (30 mmHg in systole / 20 mmHg in diastole, p < 0.001), H-2 (23/11, p < 0.001) and H-3 (16/8, p < 0.001/0.05) as compared with those in N (4/3), and this decrease significantly correlated with the resting systolic BP in H (r=-0.601, p < 0.001) and with diastolic BP (r=-0.604, p < 0.001). The handgrip exercise increased BP (42/28, 55/35 39/26 and 30/26 mmHg in Group H-1, H-2, H-3 and N, respectively). The increase in systolic BP was significantly greater in Groups H-1, H-2 and H-3 than in N (p < 0.001, p < 0.001 and p < 0.01, respectively), and the increase in diastolic BP was significantly greater in Groups H-2 than in N (p < 0.05), but not in Group H-1 and H-3. The significant decrease in BP with rest and the significant increase in BP by the exercise may represent the pathophysiological nature of the cardiovascular response in the early stage of essential hypertension.
