| Abstract: | The aim of this paper is to test whether an alteration of blood flow in microcirculation and in particular of red cell deformability is present in myocardial ischaemia. To this end we determined by the method proposed by Reid and Dormandy (J. Clin. Pharmacol. 1976, 29, 855) whole-blood filterability in 23 patients with myocardial ischaemia, in 15 clinically healthy subjects and in 99 subjects without clinical evidence of ischemic pathology displaying one or more vascular risk factors. Blood filterability turned out to be significantly lower in cases of coronary diseases than in controls (p less than 0,001), while it was lower but not significantly so, than in subjects displaying risk factors. We conclude therefore that the presence of risk factors is enough important to be considered one of the fundamental elements (though non the only one) in causing the reduction of blood-filterability encountered in ischemic cardiopathology. |
