Literature does not agree with the usefulness of exercise blood pressure (BP) in predicting hypertension or target organ damage. In this prospective 10 years of follow-up, we evaluated if exaggerated BP responses to tests may improve the prediction of left ventricular mass index (LVMI). At baseline, BP was recorded by casual measurements, and during tests using intra-arterial monitoring. The subjects were 97 healthy, untreated 35- to 45-year-old-men (34 normotensive, 29 borderline hypertensive, and 34 mild hypertensive). At 10-year follow-up, echocardiography was performed to 86 (89%) of them. Subjects not taking antihypertensive medication (n = 66) were included in the prediction of LVMI(g m-2). Echocardiography data at baseline was available from 70 (72%) of the subjects, of whom 52 did not use antihypertensive medication at follow-up. Pulse pressure (PP) at supine test (r = 0.337, P = 0.006), PP at dynamic exercise last work load (r = 0.332, P = 0.006), and PP after dynamic exercise (r = 0.316, P = 0.010) were the best BP variables achieved in tests in predicting future LVMI of the 66 subjects. Casual BP did not significantly correlate with future LVMI. The best model in predicting LVMI included PP achieved after dynamic exercise, family history of hypertension, and body mass index (BMI) (adj.R2 = 0.207). Baseline LVMI correlated significantly with future LVMI only among the 52 unmedicated subjects (r = 0.508, P<0.0001). The predictive value of baseline LVMI on future LVMI among them (adj.R2 = 0.243) was best improved by PP achieved in supine test and age (adj.R2 = 0.350). In conclusion, BP measurements during tests improved the prediction of LVMI compared with casual BP. For the first time, the pulsatile component of BP in tests was found to be the most significant BP parameter in predicting future LVMI.
