Is it important to run taking into account a heart rate or is it not dangerous to run at a high pulse?

Running at a high heart rate (if it is always) has the main disadvantage, namely a reduction of adaptive capabilities and cardiovascular system resources. Simply put, the effectiveness of your training is extremely low. In my opinion, when you train, anyway, you should have a goal, for instance to improve your physical fitness. Positive changes are always the strongest motivator to continue trainings.
If you underwent a physical examination and no pathologies or disorders were revealed, I see no reason to say about any high risk for health and life when you train or run at a high (it's a relative concept) pulse. But at the same time we can't talk about any progress if such approach to trainings is used.
