What does the term "rate pressure product" indicate?

The term "rate pressure product" is defined as the product of heart rate and systolic blood pressure. It serves as a useful measure to assess the myocardial oxygen demand during physical activities or stress. The heart rate indicates how many times the heart beats in one minute, while systolic blood pressure reflects the pressure in the arteries when the heart beats. When combined, these two factors give insights into the workload of the heart, which can help in various clinical assessments, especially in patients with cardiovascular conditions.

Understanding the rate pressure product is crucial for interpreting how well the heart is able to cope with increased demands, such as during exercise. This metric is beneficial for guiding exercise prescriptions and monitoring patients with different cardiovascular issues.
