ELI5: Why is heartrate usually only measured in BPM? Doesn't the strength of the beats matter too?

Like your heart can be beating 110BPM with light beats, but wouldn't 90BPM with much harder beats be equivalent or stronger?

Blood pressure is an extremely important measure for health diagnosis and assessment, but it requires special equipment. Heart rate, on the other hand, gives some information, though much less important or useful compared to BP, but it can be measured very easily with only a timepiece.
