Cardiovascular responses to acute exercise in patients with cerebrovascular accidents.
Blood pressure (BP) and heart rate (HR) responses to isometric hand grip, exercise with the cybex arm ergometer, and cybex fitron cycle ergometer were recorded for 19 stroke subjects and 19 control subjects matched by age and gender. Mean age in both groups was 66 years. There was no significant difference in the resting HR (controls: 69 +/- 10, patients: 70 +/- 11 beats per minute) and BP measurements (systolic--controls: 140 +/- 17, patients: 135 +/- 21; diastolic--controls 80 +/- 8, patients: 75 +/- 11mmHg). There was also no significant difference in either the mean HR (controls: 79 +/- 10, patients: 81 +/- 12 beats per minute) or BP (systolic--controls: 174 +/- 23, patients: 165 +/- 27; diastolic--controls: 98 +/- 15, patients: 92 +/- 14) response to exercise. With the arm ergometer test, the control group attained a significantly higher maximum systolic (190 +/- 23 mmHg) and diastolic blood pressure (102 +/- 15mmHg) than the stroke group (systolic 165 +/- 23; diastolic 91 +/- 10mmHg). During the leg ergometer exercise test, results were similar in both groups except that work completed was significantly higher for the control group (3592 +/- 1162kg) than for patients (2512 +/- 1348kg). None of the patients reported symptoms of dizziness, fainting, or chest pain. Prescribed exercise in stroke patients under supervision and within patient tolerance was found to be safe.
