Dr Rainer Rauramaa's of Kuopio Research Institute of Exercise Medicine, Finland, felt that regular moderate intensity exercises was the turning point in the treatment of hypertension even if results were minimal, unlike the previous understanding that the diastolic blood pressure did not improve with exercise, He also felt that there is a correlation between genetic factors and response of a persons BP to exercise. Rauramma`s study also showed that the effect of exercise on lowering BP lasts for only a few days so a person must persist for continual results. His study showed that anti-atherosclerotic effect of exercise can be seen when exercise is continued long term as it took over 3 yrs for the thickening of intima media of the carotid artery.
Finally a PET Multicenter study by Dr Rainer Hambrecht (HerzzentrumBremen, Germany) showed that if exercise was continued for at least 12 months then its benefits were as good as PCI for - Myocardial perfusion, angina threshold and exercise capacity. However exercise clearly scored more as it also improves endothelial function to slow down the progression of the disease. This markedly brings out the fact that PCI acts effectively only locally but good exercise training can impact at the very foundation of the disease. Dr Hambrecht therefore recommends that CVD patients should adhere to the professional guidelines of exercising 3-4 times a week for around 30 minutes as moderate intensity and as more exertion could increase risk of fatal arrhythmias. On the other hand he felt that he would be really happy if he could convince patients with coronary artery disease to take part in a moderate exercise program.
