Onsy, Mohamed Talaat Ali, Hassan Ali El-Kiki, Rania Ali HegazyAbstractAimTo compare 3D steady-state free-precession (SSFP) non-contrast magnetic resonance angiography (NC-MRA) with contrast-enhanced MRA (CE-MRA) for quantitative and qualitative analysis of thoracic arteries in pediatric patients with congenital heart disease.MethodologyForty patients with thoracic vascular anomalies (22 boys &18 girls) ranging in age between 6 months and 14 years (mean age 4.58 ± 4.5) were included in this prospective study. Measurements of the thoracic arteries were taken by 3D SSFP NC-MRA &CE-MRA. Image quality was assessed using a four-point score. Pearson's and Spearman's Correlation Coefficients were calculated for correlation analysis while Student's t and Mann-Whitney U tests were used for comparative analysis, Bland-Altman plots were employed to demonstrate the level of agreement between the 2 techniques.ResultsMeasurements from NC-CMRA images were comparable to those from CE-MRA. All measures highly correlated (r > 0.9), 3D SSFP NC-MRA exhibited a significantly higher image quality score than contrast- enhanced MRA, the mean difference was significantly lower than that of the 3D SSFP; (p-value

Authors: Ling Y, Tang S, Cao Y, Fu C Abstract Background: Increasing evidence states that the plasma lipoprotein-associated phospholipase A2 (Lp-PLA2) levels and apolipoprotein particles are regarded as the risk maker for cardiovascular heart disease. Nevertheless, the issue about whether Lp-PLA2 is associated with apolipoprotein particles in individuals who have been diagnosed as stable coronary artery disease (CAD) remains largely unexplored. Method: All 569 participants engaged in this research, who never took lipid-lowering drugs, had been divided into groups by the coronary angiography (CAG), namely, stabl...

AbstractAccurate pulmonary artery (PA) imaging is necessary for management of patients with complex congenital heart disease (CHD). The ability of newer imaging modalities such as 3D rotational angiography (3DRA) or phase-contrast magnetic resonance angiography (PC-MRA) to measure PA diameters has not been compared to established angiography techniques. Measurements of PA diameters (including PA stenosis and PA stents) from 3DRA and non-contrast-enhanced PC-MRA were compared to 2D catheter angiography (CA) and multi-slice computed tomography (MSCT) in a swine CHD model (n  = 18). For all PA segments 3DRA had ...

Conclusion Among patients with severe degenerative aortic stenosis, vitamin D deficiency is common. We found a significant association between left ventricular wall thickness and vitamin D levels, suggesting a potential role of this hormone in modulating hypertrophic remodelling in these patients. However, future larger studies are certainly needed to confirm our findings and to define their prognostic implications.

Objective To investigate the association between non–high-density lipoprotein cholesterol/apolipoprotein A-I and monocyte/high-density lipoprotein cholesterol ratio and degree of coronary artery stenosis proven by coronary angiography. Methods A total of 1867 patients were enrolled into this study and analyzed retrospectively. Three hundred eighty-five non-coronary artery disease hospitalized patients were selected as control group, 1482 patients diagnosed as coronary artery disease were classified into three subgroups according to the tertiles of their SYNTAX score. We compared the level of non–high-densi...

AbstractPurpose of ReviewEstablishing a diagnosis of ischemic heart disease (IHD) in women, including assessment for coronary microvascular dysfunction (CMD) when indicated, can be challenging. Access to performance of invasive testing when appropriate may be limited, and noninvasive imaging assessments have evolved. This review will summarize the various noninvasive imaging modalities available for the diagnosis of IHD and CMD in women, outlining indications, performance modalities, advantages, and limitations.Recent FindingsWhile stress echocardiography and single photon emission computed tomography (SPECT) myocardial pe...

CONCLUSIONS: This case series provides novel data quantifying the decrease in PVR after relief of Fontan circuit obstruction, suggesting a mechanism for symptomatic improvement after intervention. These data are a compelling addition to the longterm management of this complex patient population. PMID: 32999096 [PubMed - in process]

CONCLUSION: In New Zealand patients after their first MI there is a three-fold variation in one-year mortality based on ethnicity. At least half of the inequity in outcomes for Māori, and three-quarters for Pacific people, is associated with differences in preventable or modifiable clinical factors present at, or prior to, presentation.

Conclusion: The serum PDGF concentration in patients with acute coronary syndrome was significantly increased, especially in the local coronary artery. The serum Ang-1 in the coronary artery was significantly increased in patients with acute myocardial infarction and was related to the degree of coronary artery stenosis. Coronary sinus PDGF and Ang-1 levels can reflect the severity of lesions in patients with acute coronary syndrome. PMID: 32963822 [PubMed]
