Aims: The study aims at the evaluation, of patients with chest pain and uninjured coronary arteries, and the impact of diabetes mellitus on coronary microcirculation. Moreover we want to verify whether a correlation between myocardial scintigraphy results and coronary angiography or not. Methods: The study population included 316 patients (173 males,143 females) with uninjured coronary arteries. Patients with chest pain (208) were divided into two populations: diabetics (72) and non-diabetics (136).We compared 66 patients with a myocardial scintigraphy with results of angiographic indexes. On angiographic images we evaluated, on the three major epicardial, Gibson's indexes (TFC, MBG), the Yusuf's index(TMBS) and a new index: Total Timi Frame Count (TTFC). Results: Patients with positive scintigraphy had a worse TMBS than patients with negative scintigraphy (p= 0.003) and a lower TFC of healthy vessels than diseased vessels (p=0.0001).We found a worse coronary microcirculation in diabetic patients with lower values of MBG and TMBS (p=0.02),compared with non- diabetics. New index TTFC is usually higher in diabetics than non-diabetic patients. Conclusion: The study of microcirculation by coronary angiography and myocardial scintigraphy shows a good correlation between two methods. The analysis of diabetic patients and non-diabetic with chest pain and uninjured coronary arteries has led to assess that diabetic population has a major microcirculation disease. © Versita Sp. z o.o.

Abstract

Aims: The study aims at the evaluation, of patients with chest pain and uninjured coronary arteries, and the impact of diabetes mellitus on coronary microcirculation. Moreover we want to verify whether a correlation between myocardial scintigraphy results and coronary angiography or not. Methods: The study population included 316 patients (173 males,143 females) with uninjured coronary arteries. Patients with chest pain (208) were divided into two populations: diabetics (72) and non-diabetics (136).We compared 66 patients with a myocardial scintigraphy with results of angiographic indexes. On angiographic images we evaluated, on the three major epicardial, Gibson's indexes (TFC, MBG), the Yusuf's index(TMBS) and a new index: Total Timi Frame Count (TTFC). Results: Patients with positive scintigraphy had a worse TMBS than patients with negative scintigraphy (p= 0.003) and a lower TFC of healthy vessels than diseased vessels (p=0.0001).We found a worse coronary microcirculation in diabetic patients with lower values of MBG and TMBS (p=0.02),compared with non- diabetics. New index TTFC is usually higher in diabetics than non-diabetic patients.
