Decreasing the Rate of False Negative Invasive Coronary Angiography by Determining Combined two Clinical Criteria in Patients with Presumped Chronic Stable Angina

Abstract

rates of Invasive Coronary Angiography (ICA.)is of paramount importance in decreasing the wasted local resources which are already demanding.

OBJECTIVES: to find clinical criteria associated with low rates of FN.s results of ICA.in patients with Chronic Stable Angina(CSA

PATIENT AND METHOD: 120 patients with presumed Chronic Stable Angina(CSA.), referred to ICA.; divided  according to the presence of HT, Diabetes(DM.)  ; then  to the presence of combined DM\Hypertension.

RESULTS: FN rates in subgroups of HT.;DM. ;and DM\HT. were as follows:35;9;4\60(of the total negative ICA. Results).

CONCLUSIONS:  males , smoking ,and HT. were not associated with decreasing the FN. rates of ICA, ;while the presence of DM\HT. was  more closely associated than the presence of DM. alone , in decreasing such a rate .
