- Introduction: Data on the prognostic value of hypertensive response to exercise in cardiovascular disease are limited. The aim was to determine whether SBP reactions during exercise have any prognostic value in relation to the long-term risk of stroke and myocardial infarction (MI).Patients and methods: A representative cohort of men from Gothenburg, Sweden, born in 1913, who performed a maximum exercise test at age 54 years, (n = 604), was followed-up for a maximum of 44 years with regard to stroke and MI. Results: Among the 604 men, the mean resting and maximum SBP was 141.5 (SD 18.8) and 212.1 (SD 24.6) mmHg, respectively. For maximum SBP, the risk of stroke increased by 34% (hazard ratio 1.34, 95% confidence interval 1.11-1.61) per 1-SD increase, while no risk increase was observed for MI. The highest risk of stroke among blood pressure groups was observed among men with a resting SBP of at least 140 mmHg and a maximum SBP of at least 210 mmHg with an hazard ratio of 2.09 (95% confidence interval 1.29-3.40), compared with men with a resting SBP of less than 140 mmHg and a maximum SBP of less than 210 mmHg, independent of smoking, blood glucose, cholesterol and BMI.Conclusion: Among middle-aged men with high resting and maximum blood pressure during maximum exercise workload, an increased risk of stroke was observed but not for MI. Further studies with larger sample sizes are needed to investigate the underlying mechanisms of the increased risk of stroke among individuals with hypertensive response to exercise.

- Background Low aerobic capacity has been associated with increased mortality in short-term studies. The aim of this study was to evaluate the predictive power of aerobic capacity for mortality in middle-aged men during 45-years of follow-up. Design The study design was a population-based prospective cohort study. Methods A representative sample from Gothenburg of men born in 1913 was followed from 50-99 years of age, with periodic medical examinations and data from the National Hospital Discharge and Cause of Death registers. At 54 years of age, 792 men performed an ergometer exercise test, with 656 (83%) performing the maximum exercise test. Results In Cox regression analysis, low predicted peak oxygen uptake (VO2max), smoking, high serum cholesterol and high mean arterial blood pressure at rest were significantly associated with mortality. In multivariable analysis, an association was found between predicted VO2max tertiles and mortality, independent of established risk factors. Hazard ratios were 0.79 (95% confidence interval (CI) 0.71-0.89; p<0.0001) for predicted VO2max, 1.01 (1.002-1.02; p<0.01) for mean arterial blood pressure, 1.13 (1.04-1.22; p<0.005) for cholesterol, and 1.58 (1.34-1.85; p<0.0001) for smoking. The variable impact (Wald's (2)) of predicted VO2max tertiles (15.3) on mortality was secondary only to smoking (31.4). The risk associated with low predicted VO2max was evident throughout four decades of follow-up. Conclusion In this representative population sample of middle-aged men, low aerobic capacity was associated with increased mortality rates, independent of traditional risk factors, including smoking, blood pressure and serum cholesterol, during more than 40 years of follow-up.
