[Clinical and hemodynamic aspects of non-obstructive coronary lesions. A comparative retrospective study].

Purpose: To study the clinical and hemodynamic aspects of a group of patient presenting non-obstructive coronary lesions.

Methods: We reviewed 963 coronary angiographies performed at a same institution. The 52 patients presenting only stenosis < or = 50% after semi-quantitative measurement composed group I, which was compared with two other groups consisted of 52 patients each: one, with patients presenting univascular lesion > 50% (group II) and the other with normal coronary arteriographies (group III).
