Key result
Angiotensin used as a pharmacoangiographic agent improved the diagnostic value of angiography in about 70% of cases by enhancing the filling of smaller arteries.
Why the study?
Does angiotensin improve the diagnostic value of angiography in patients undergoing selective arterial catheterization?
Does angiotensin improve the diagnostic value of angiography in patients undergoing selective arterial catheterization?
The use of angiotensin as a pharmacoangiographic agent improves the diagnostic value of angiography by enhancing the filling of smaller arteries.
May aid selective angiography visualization; hypothesis-generating from Level 5 data and requires prospective validation before practice change.
Angiotensin was investigated as a pharmacoangiographic agent in 80 patients, employing selective catheterization of various arteries. The diagnostic value of angiography was improved in about 70% of cases. This improvement usually consisted of enhanced filling of smaller arteries with a higher concentration of contrast material. In 3 cases, newly-formed tumor vessels could be demonstrated only with the aid of angiotensin.

Ekelund et al. (1974) studied Patients undergoing angiography (n=80). Angiotensin was evaluated on Improvement in diagnostic value of angiography. Angiotensin used as a pharmacoangiographic agent improved the diagnostic value of angiography in about 70% of cases by enhancing the filling of smaller arteries.
