| pubmed-article:7177467 | pubmed:abstractText | An investigation conducted on a series of 1010 patients selected without regard to age, sex, or pathology showed that orthostatic hypotension is very common (about 35%), especially in aged and hypertensive subjects. It was found that cardiovascular causes play a by no means unimportant part in its determination. Only 20% of the cases observed were attributable to drug treatment. | lld:pubmed |
