The relevance of performing exercise test before starting supervised physical exercise in asymptomatic cardiovascular patients with rheumatic diseases

ABSTRACT

OBJECTIVES: To evaluate the impact and risk factors associated with an abnormal exercise test (ET) in systemic inflammatory rheumatic disease (SIRD) patients before commencing supervised physical exercise. METHODS: A total of 235 SIRD patients were enrolled in three controlled clinical trials, including 103 RA, 42 SLE and 57 AS patients. The control group consisted of 231 healthy, sedentary subjects matched for age, gender and BMI. All performed an ET, according to Bruce's or Ellestad's protocol. Cardiovascular disease risk factors, medications, comorbidities and details of each SIRD were assessed.RESULTS: SIRD patients had a higher percentage of abnormal ETs compared with the control group, especially exercise hypertensive behaviour, higher oxygen consumption, higher resting heart rate and heart rate at the first minute of recovery, and chronotropic incompetence (C-Inc) (P < 0.001)...
