Coronary Slow Flow

چکیده
oronary angiography (CAG) is the gold standard for diagnosis of coronary artery disease (CAD). Of all patients referred for angiography, up to 20% have normal coronary arteries.1,2 Though noncoronary causes of chest pain may be identified in this population with normal coronaries, it has long been recognized that angina may still be present. An example of this is cardiovascular syndrome X, a condition predominantly affecting females who are found to have normal CAG following abnormal exercise stress studies.3

Evaluation of Electrocardiogram Changes in Patients with Slow Coronary Flow
Background: Slow coronary flow (SCF) is defined as a condition in which in spite of no evidence of coronary occlusion or stenosis in angiography, there is delayed pacification of the vessels after the injection of a contrast agent. There are several studies about electrocardiogram (ECG) changes in these patients, but changes like OLD MI, RBBB, LBBB, LVH and ST-T wave have not b...

متن کاملNicorandil effect on myocardial perfusion in patients with slow coronary flow phenomenon assessment by gated myocardial perfusion SPECT
Introduction:Patients with the coronary slow flow phenomenon (SCF) frequently experience angina episodes. The purpose of this study was to determine efficacy of nicorandil in myocardial perfusion in patients with SCF. Methods: Twenty patients (50.85 ± 12.96 y) with SCF were studied. We evaluate coronary slow flow according to protracted thrombolysis in m...
متن کاملCorrelation between serum levels of cystatin C and coronary slow flow and body mass index in men
Background: Cystatin C (Cys C) as a cysteine protease inhibitor is produced in a constant level from all nucleated cells. The purpose of this study was to investigate the correlation between serum levels of Cys C and coronary slow flow (CSF) and body mass index (BMI) in men. Methods: This investigation is in the form of a descriptive-analytical study. The statistical population was all non-act...
متن کاملAssociation Between Left Anterior Descending Artery Length with Coronary Artery Dominance: An Angiographic Study
Introduction: Although left anterior descending (LAD) artery supplies a large portion of the myocardium, the amount of blood supply provided by LAD is depended on the length of the LAD. The aim of the current study was to evaluate the association between coronary artery dominance and LAD anatomic types in patients with normal epicardial coronary arteries. Methods:...
متن کاملEvolution of Coronary Flow in an Experimental Slow Flow Model in Swines: Angiographic and Pathological Insights
OBJECTIVE Pathomechanism of coronary slow flow phenomenon remains largely unclear now. Present study observed the pathological and angiographic evolution in a pig model of coronary slow flow. METHODS Coronary slow flow was induced by repeat coronary injection of small doses of 40 µm microspheres in 18 male domestic pigs and angiographic and pathological changes were determined at 3 hours, 7 d...
