[Isometric load tolerance in patients with postinfarct cardiosclerosis]
Insights
Patients with post-infarction cardiosclerosis and cardiac pain syndrome show reduced hand strength and tolerance to isometric exercise. Severity of chronic coronary insufficiency primarily impacts tolerance to dynamic exercise.
Area of Science:
- Cardiology
- Exercise Physiology
Background:
- Post-infarction cardiosclerosis affects patient tolerance to physical exertion.
- Clinical presentation varies, influencing physiological responses.
- Understanding these differences is crucial for rehabilitation.
Purpose of the Study:
- To compare the tolerance to isometric and dynamic loads in patients with post-infarction cardiosclerosis.
- To investigate the influence of clinical picture, specifically cardiac pain syndrome (cardialgia), on exercise tolerance.
- To assess hemodynamic responses during different types of exercise.
Main Methods:
- Comparative study involving 80 patients with post-infarction cardiosclerosis.
- Assessment of hand grip strength.
- Evaluation of tolerance to isometric and dynamic exercise.
- Monitoring of systolic arterial pressure and pulse during isometric loading.
Main Results:
- Patients with cardialgia exhibited weaker hand strength compared to healthy individuals.
- Cardialgia significantly diminished tolerance to isometric load.
- Isometric loading caused a greater increase in systolic arterial pressure in patients than in controls.
- Severe post-infarction angina pectoris was associated with pulse changes during isometric exercise.
- Dynamic exercise tolerance was primarily limited by the severity of chronic coronary insufficiency.
Conclusions:
- Cardiac pain syndrome is a key factor limiting isometric exercise tolerance in post-infarction cardiosclerosis patients.
- Hemodynamic responses, particularly systolic blood pressure, are exaggerated during isometric exercise in these patients.
- Chronic coronary insufficiency severity dictates tolerance to dynamic exercise, highlighting the need for tailored exercise prescriptions.
Abstract:
The work deals with the comparative study of the tolerance of 80 patients with post-infarction cardiosclerosis with a different clinical picture of the disease to isometric and dynamic loads. It was established that the strength of the hands was weaker in patients with the cardiac pain syndrome than in healthy individuals. In addition to this in patients with cardialgia, the tolerance to isometric load was diminished. In isometric loading the systolic arterial pressure in all patients increases much more than in individuals of the control group, and in patients with severe post-infarction angina pectoris there are also changes in the pulse. Cardialgia has a determining effect on the tolerance to isometric load, whereas the dynamic test tolerance is mainly limited by the severity of chronic coronary insufficiency.
