Aerobic Exercise Training & the Autonomic System In Patients After Myocardial Infarction or Stroke
The Effect of Aerobic Exercise Training On the Function of the Autonomic System In Patients That Have Suffered Myocardial Infarction or Stroke
The purpose of this study is to examine the effect of Aerobic Physical Activity on the function of the Autonomic System in patients after Myocardial Infarction or Stroke.
A secondary objective is to examine whether it is possible to predict which of the patients will most benefit from physical activity (exercise training), taking into account, genetic factors such as Polymorphism of ACE (Angiotensin Converting Enzyme)

Descripción detallada
Imbalance in autonomic cardiovascular function has been shown to increase the risk of ventricular arrhythmias and sudden death in patients with coronary artery disease (CAD), after myocardial infarction and after stroke. Heart rate variability (HRV) reflects the autonomic tone of the heart. Under these conditions there is an increased sympathetic adrenergic tone and reduced parasympathetic activity. The effect of aerobic rehabilitation on the Sympathetic-parasympathetic control has been examined. exercise training alters sympatho-vagal control of heart rate variability (HRV) towards parasympathetic dominance in patients after acute myocardial infarction (MI) and in diabetic patients. To our knowledge, in post-stroke patients this issue hasn't been investigated.
It is known that different people react differently to physical training. There is a difference of opinion in literature concerning the function of Genetic parameters, such as the Polymorphism of ACE (Angiotensin Converting Enzyme), in hemodynamic Reactions following Physical Activity and whether there is a connection between Polymorphism and physical performance..
Objectives To examine the effect of Aerobic Physical Activity on the function of the Autonomic System in patients after Myocardial Infarction or Stroke.
A secondary objective is to examine whether it is possible to predict which of the patients will most benefit from physical activity (exercise training), taking into account, genetic factors such as Polymorphism of ACE (Angiotensin Converting Enzyme)
Research Population The research subjects include a) patients after Myocardial Infarction between the ages 20 - 80 , who underwent percutaneous coronary interventions (PCI), and b) patients after a first Stroke between ages 20 - 80, up to two months after the stroke, with a NIH Stroke Score of 6 - 20 and who are able to cooperate and follow instructions.
Methods Part A This research will examine the effect of Aerobic Physical Activity on the function of the Autonomic Nervous System and on various physiological and clinical factors such as B.P., blood sugar level, tryglycerides, HDL, LDL, CRP and aerobic physical fitness, in 70 cardiac patients who participate in the Heart Rehabilitation Program at the Hadassah Hospital on Mt. Scopus and in 30 post Stroke patients.
Control Group I Includes about 70 cardiac patients and about 30 post Stroke patients, thate will NOT include in the Exercise Training Program and ARE suitable with regards to age, sex, and clinical background.
Group II Includes about 30 healthy individuals, suitable for the research groups with regard to age and sex, and have no known cardio-vascular disease and who will participate in Aerobic Exercise Training Program for 3 months.
At the commencement and end of the research:
Patients in the research and control groups will undergo the following tests:-
- Stress Test
- Measurement of Heart Rate Variability by means of a "Holter" monitor.
- General Blood tests (Triglycerides, HDL, LDL, sugar and HB.A1C.CRP)
- Quality of life according to SF questionnaire.
- B.P and Pulse at rest.
- NIH Stroke Scale
- MAS (Motor Assessment Scale).
- FIM (Functional Independence Scale)
- Walking Speed Test; (the distance covered in two minutes) at a comfortable speed. During the test the patient is connected to a Polar Watch (heart rate monitor) to check the Heart Rate.
Physical (Exercise)Training
- Each patient will receive a personal training program and his optimal heart rate is determined by the results the stress test according to a Borg scale - a scale for assessing, subjectively, the training intensity level. RPE (Rating of perceived exertion scale)
- Duration of program: 3 months, 2 sessions a week, each session lasting 60 minutes.
- Session includes about 15 minutes of warm-up, the main part - aerobic workout on exercise machines for 35 minutes, and relaxation for 10 minutes.
- The main part includes work on the following fitness machines; treadmill, bicycle and arm ergometria.
- The heart rate is monitored constantly during the training, by means of a Polar Watch.
- At the start and end of each session, blood pressure is measured, and if necessary also during the session.
- The intensity of effort will be examined by means of the Borg Scale (RPE) for a subjective assessment of level of difficulty.
Part B Blood tests at the end of the training program will include a test of ACE Insertion/Deletion Polymorphism.
