Mixed Tenses Analysis

Topics in Health: Live Organ Donations - Youth Media Los Angeles Collaborative

To boost donation, however, some centers have accepted donors who have a health condition, such as high blood pressure, that would have ruled them out a few years ago.

How do the verb tense of the main "event" (the centers accepting donors) and the verb tense of human participant "attributes" (the donors having health conditions) relate? I take "Some centers have accepted donors" to mean that the centers in the past accepted such donors and in the relevant present accepts such donors. Should I take "donors have a health condition" to mean that donors accepted in the past had health conditions at the moment of acceptance, and that donors that are accepted in the relevant present have health conditions now?

You're trying to read too much into this.

Change 'who have' to 'with' and see if it makes sense to you now.

Would it have difference meanings if "have a health condition" is replaced by "had a health condition"?

It could suggest that they no longer have that health condition.

That could also suggest that they no longer had the condition when they were accepted - which is against the meaning of the original.

If "have a health condition" becomes "have had a health condition", would native readers sense some extra meanings in the example?

The meaning would be different, not extra.

How different?

How different?

Guess.

Guess.

A present perfect situation shadowed by another present perfect situation could mean the same as past perfect situation?
