The algorithm called eliot
and associated option set by --eliot-tfs
can be used for this. It is specific to this PDF but if you have such PDFs, it might be useful. For example:
$ pdftitle -p he2020.pdf -a eliot --eliot-tfs 1
Salt Reduction to Prevent Hypertension and Cardiovascular Disease
--eliot-tfs 1
means, do not use the font with maximum size (which is T), but use the font size having the second maximum size, which is the title here.

In this the first paragraph begins with a very large single character and so the title extracted is 'T' one possibility is to check for single letter and then go for the next font size.
