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...

The coronary slow flow phenomenon (CSFP) is characterized by a delayed coronary blood flow in the absence of an obstructive coronary artery disease. Although the relation between the CSFP and myocardial ischemia has been reported previously, there is no knowledge about the relationship between the CSFP and the conduction system disorder. In this case report, we describe a patient with the CSFP ...

To the Editor: I read with interest the recent paper by Hawkins et al1 in which they investigated the prevalence and clinical features of the coronary slow flow phenomenon (CSFP). They identified 1,714 consecutive patients who underwent coronary angiography and included 158 patients with normal coronary arteries and normal left ventricular function. Of this subgroup, 96 subjects had CSF in at l...

BACKGROUND Coronary slow flow phenomenon (CSFP) is a functional and structural disease that is diagnosed by coronary angiogram. OBJECTIVES To evaluate the possible association between CSFP and small artery elasticity in an effort to understand the pathogenesis of CSFP. METHODS The study population comprised 12 patients with normal coronary arteries and CSFP and 12 with normal coronary arter...

INTRODUCTION Slow coronary flow (SCF) is a well-known angiographic finding; however, the pathophysiology of SCF remains only partially understood. In this study, we have examined the risk factors of slow coronary flow. METHODS Seventy patients with angiographically proven SCF were studied along with 60 control participants. Patients were divided into 2 groups based on the angiographic finding...

BACKGROUND To improve clinical outcomes, noninvasive imaging modalities have been proposed to measure and monitor atherosclerosis. Endothelial dysfunction is considered the first stage in the development of atherosclerosis. Brachial artery flow-mediated dilatation (FMD) has been impaired in patients with coronary slow flow (CSF). Recently, color M-mode derived propagation velocity of descending...

In the last twenty years, the treatment of coronary heart disease with cardiac catheterization has greatly advanced. This therapeutic approach has had unexpected side effects, however, for which solutions must be found, particularly in the are of interventional cardiology. The “noreflow” phenomenon, a side effect, is an uncommon and critical occurrence and, if not reversed, causes a high rate o...

myocardial fractional flow reserve (ffr) is a new index of the functional significance of intermediate coronary stenoses that is calculated from pressure measurements made during coronary arteriography. the aim of this study was to evaluate the correlation between non-hyperemic coronary pressure dicrotic notch and fractional flow reserve (ffr). a consecutive of 114 patients (73 men and 41 women...
