In the era of coronavirus disease 2019 (COVID-19) pandemic, acute cardiac injury (ACI), as reflected by elevated troponin above 99th percentile, has been observed in 8%-62% patients with COVID-19 infection highest incidence and mortality recorded severe infection. Apart from clinically electrocardiographically discernible causes ACI, such myocardial infarction (MI), other need to be considered ...

OBJECTIVES To test the image quality and feasibility of a sequential low radiation dose protocol for hybrid cardiac PET/CT angiography (CTA). BACKGROUND Multidetector computed tomography (MDCT) is a non-invasive method for coronary angiography. The negative predictive value of MDCT is high but perfusion imaging has a role in detecting functional significance of coronary lesions. This has enco...

Introduction and objectives: The presence of comorbidities in elderly patients with non-ST-segment elevation acute coronary syndrome worsens its prognosis. objective the study was to analyze impact burden decision using invasive management these patients. Methods: A total 7211 > 70 years old from 11 Spanish registries were included. Individual data analyzed a common database. We assessed 6 the...

The study tested the prevalence of graft vessel disease (GVD) in 54 paediatric heart transplant (HTx) patients (32 male, age 0-17 years) who underwent coronary angiographic investigations (N=117). These were evaluated according to the Stanford classification and additional criteria (peripheral obliterations, diameter fluctuations, pathologic tapering) were applied for risk assessment (no GVD/mi...

Background: There are only a few reports concerning the genetic risk factors for coronary artery disease (CAD). However, 2 polymorphisms of rs10757274 and rs2383206 on chromosome 9p21.3 have been shown recently to be associated with CAD in certain populations. This is the 1st study to investigate their validity and association with CAD in a sample of the Iranian population. Methods: Genomic DNA...

OBJECTIVE To compare single-photon-emission computed tomography (SPECT) imaging scans using 201Tl and 99mTc-MIBI in detection of viable myocardium, in regions compromised by infarction. METHODS Thirty-two (59.3 +/- 9.8 years old and 87% male) myocardial infarction patients were studied. All had Q waves on the ECG and left ventricle ejection fraction of < 50%. They underwent coronary and left ...

Abstract Background We developed machine learning models to predict the need for coronary angiography, recurrent acute syndromes (ACS) and 1-year survival in patients with chest pain normal high-sensitivity troponins. also studied whether hs-troponin levels within range convey predictive information on these outcomes. Purpose could reliably survival, risk of future ACS rule out unnecessary angi...

Objective Patients with rheumatoid arthritis (RA) are at increased risk of coronary artery disease (CAD) and seem to develop more severe acute syndromes (ACS) than the general population. Because few studies have investigated CAD distribution in context or stable RA, objective was investigate whether this is due a different severity stenoses (versus non-RA), resulting clinical manifestation CAD...

Numerous studies on cerebral angiography have been conducted since Egas Moniz's study in 1927. It is known that complications due to cerebral angiography are mainly resulted from the contrast medium. We have selected organic tri-iodide solution as a contrast medium because it is safe and offers a high contrast. Urografin (60% and 76%) were used in 1869 cerebral angiographies. Present studies we...

OBJECTIVE The aim of the present investigation was to explore probable association of renal artery stenosis (RAS) with coronary artery disease (CAD) and the prevalence of renal artery stenosis (RAS) in patients with CAD. PATIENTS AND METHODS This study comprised 165 consecutive patients with CAD, including 52.7% males and 47.2% females with respective mean ages of 60.3 ±8.9 and 59.5±10.1. The...
