Based on prior knowledge, the maximum heart rate achieved (MaxHR) can be used as a significant feature in determining whether a patient has heart disease. Generally, a higher maximum heart rate achieved is associated with a healthier heart, while a lower maximum heart rate achieved may indicate the presence of heart disease.

The provided dictionary shows 5 typical maximum heart rate values for each target class, "no" and "yes". The "no" class refers to patients whose coronary angiography does not show heart disease, while the "yes" class corresponds to patients with a positive diagnosis.

For the "no" class, the MaxHR values range from approximately 156 to 162 bpm (beats per minute). These values suggest a relatively higher maximum heart rate, which can be considered normal or indicative of a healthy heart.

On the other hand, the "yes" class shows MaxHR values ranging from around 130 to 155 bpm. These values indicate a slightly lower maximum heart rate, which may be associated with heart disease.

It is important to note that these values are just examples and may vary depending on the specific dataset and population studied.
