We investigated zinc and copper levels in angiographically defined obstructive coronary artery disease (CAD) in patients undergoing elective coronary angiography in El-Shaab Hospital, Sudan. We performed a cross-sectional study. One hundred forty-two patients were enrolled. Sociodemographic and medical characteristics were collected using a questionnaire. Glucose, lipid, zinc, and copper levels...

background and objective: obstructive sleep apnea (osa) is frequent and in some degree it affects about 24% of male and 9% of female in middle age adults. this study aimed to assess the association between risk of osa and cad. materials and methods : this case-control study was performed among 184 patients with a history of coro- nary angiography in two catheter labs at hospitals in qom, iran. ...

Background: It has been implicated that obstructive sleep apnea (OSA) is associated with increased risk of cardiovascular disease including stroke, myocardial infarction, coronary artery disease (CAD) and hypertension. The aim of this study was to investigate the correlation between OSA and severity of atherosclerosis assessed by angiography. Methods: This study included 337 patients ...

Abstract Background The clinical value of positive family history premature coronary artery disease (CAD) in risk prediction cardiovascular diseases is controversial. While an association with factors and manifestation has been described observational studies, it not implemented clinically established algorithms. Purpose We evaluated the CAD factors, presence obstructive CAD, long-term mortalit...

Abstract Funding Acknowledgements Type of funding sources: None. Introduction The steady decline in test positivity among patients with suspected coronary artery disease (CAD) has raised interest developing strategies to identify who may not require testing. updated PROMISE minimal-risk tool (PMRT) was developed specifically for this purpose, but never tested our population. aim study assess th...

T he debate about the role of coronary revascularization on top of optimal medical therapy for patients with obstructive coronary artery disease (CAD) and stable symptoms remains vibrant. Despite significant progress in understanding risk factors for atherosclerosis and altering those risk factors at the level of populations, the " double whammy " of the aging of the population as a whole, coup...

Myocardial perfusion single photon emission computed tomography (SPECT) is widely used in assessing coronary artery disease (CAD) owing to its proven efficacy extensive clinical experience. Like other functional tests, myocardial SPECT recommended for the diagnosis of obstructive CAD, risk stratification assessment, and treatment decision making. Besides quantifying left ventricular volume, glo...

PURPOSE Current evidence supports a robust association between obstructive sleep apnea syndrome (OSAS) and the risk of coronary artery disease (CAD). YKL-40, a 40 kDa heparin- and chitin-binding glycoprotein, is found to be associated with the presence of CAD. This study aims to examine the association of serum levels of YKL-40 with the presence and severity of CAD in patients with OSAS. METH...

INTRODUCTION AND AIMS Differentiation of ischemic from non-ischemic etiology in heart failure (HF) patients has both therapeutic and prognostic implications. One possible approach to this differentiation is direct visualization of the coronary tree. Multidetector computed tomography (MDCT) has emerged as an alternative to invasive coronary angiography (ICA), but its performance and additional c...

We investigated the diagnostic accuracy of computed tomography angiography (CTA) versus myocardial perfusion imaging (MPI) for detecting obstructive coronary artery disease (CAD) as defined by conventional quantitative coronary angiography (QCA). Sixty-three patients who were enrolled in the CorE-64 multicenter study underwent CTA, MPI, and QCA imaging. All subjects were referred for cardiac ca...
