Figure 2 Cumulative survival measured from the time of the maximal symptom-limited exercise test in 89 hypertrophic cardiomyopathy patients aged 50 years. The 21 patients who demonstrated abnormal systemic blood pressure response to exercise (ABPR; broken line) showed significantly reduced survival compared with the 68 patients with a normal blood pressure (BP) response (solid line), over an average follow-up period of 4.7 ± 3.7 years.
