[Exercise testing in probable primary hypokinetic cardiomyopathies].
50 patients with primary congestive cardiomyopathy underwent one or several exercise tests at yearly intervals in order to evaluate exercise capacity and to assess the prognosis. Three parameters were studied: the workload, the elevation of the systolic blood pressure (SBP) on exercise and the appearance of premature ventricular beats (PVB) on exercise or during the recovery phase. The results show that when the work loads > 120 watts, an elevation of SBP greater than or equal to 50 mmHg and the appearance of less than 3 PVB per minute were compatible with a moderate degree of physical exertion. On the other hand these same poor prognostic factors were associated with a higher mortality rate after 20 months follow-up.
