Positron emission tomography in ischemic heart disease

Publication date: August 2019Source: Revista Portuguesa de Cardiologia (English Edition), Volume 38, Issue 8Author(s): Beatriz Saldanha Santos, Maria João FerreiraAbstractNon-invasive assessment of ischemic heart disease remains a challenging task, even with a large armory of diagnostic modalities. Positron emission tomography (PET) is an advanced radionuclide technique that has been available for decades. Originally used as a research tool that contributed to advances in the understanding of cardiovascular pathophysiology, it is now becoming established in clinical practice and is increasingly used in the diagnosis and risk stratification of patients with ischemic heart disease. PET myocardial perfusion imaging has a mean sensitivity and specificity of around 90% for the detection of angiographically significant coronary artery disease, and is also highly accurate for assessing the prognosis of patients with ischemic heart disease. Depending on the radiotracer used, it can provide information not only on myocardial perfusion but also on myocardial metabolism, which is essential for viability assessment. The potential of this imaging technique has been further increased with the introduction of hybrid scanners, which combine PET with computed tomography or cardiac magnetic resonance imaging, offering integrated morphological and functional information and hence comprehensive assessment of the effects of atherosclerosis on the myocardium. The scope of this review is to ...

Authors: Kay FU, Canan A, Abbara S Abstract Coronary computed tomography angiography (CCTA) is a well-validated and noninvasive imaging modality for the assessment of coronary artery disease (CAD) in patients with stable ischemic heart disease and acute coronary syndromes (ACSs). CCTA not only delineates the anatomy of the heart and coronary arteries in detail, but also allows for intra- and extraluminal imaging of coronary arteries. Emerging technologies have promoted new CCTA applications, resulting in a comprehensive assessment of coronary plaques and their clinical significance. The application of computational...

This study investigated ICD-lead intracardiac parameters over a long duration in patients with ARVC and HCM and compared these parameters with those of a control group. We included 50 patients (mean age, 55.2 ± 17.2 years; 26% female) with ICD leads in the right ventricular apex, and compared 7 ARVC and 14 HCM patients with 29 control patients without structural heart disease. ICD-lead parameters, including R-wave amplitude, pacing threshold, and impedance during follow-up, were compared. The difference in these parameters between the time of implantation and year 5 were also compared. There were no significant diff...

Authors: Li L, Wu F, Xie Y, Xu W, Xiong G, Xu Y, Huang S, Wu Y, Jiang X Abstract A previous study and a gene-annotation enrichment analysis for potential targets of the microRNA miR-202-3p both suggest that this microRNA might be implicated in cardiovascular and metabolic diseases. In the present study, the role of miR-202-3p in the pathogenesis of coronary heart disease (CHD) was explored. We conduct a case-control study to detect the expression levels of miR-202-3p in peripheral blood cells and found that miR-202-3p expression was significantly higher in CHD cases than in controls (P

ConclusionComorbidity increased the rate of all-cause, but not MS-specific, hospital admissions. Hospitalization rates were higher during the earlier stages of MS. Therefore, recognizing and managing comorbidity in the MS population, especially early in the disease course, will likely have the biggest impact on reducing overall hospital admissions.

ConclusionsFreedom from reoperation after CVR repair was 93% at 5 years and 86% at 10 years. A small proportion of patients who do not undergo diverticulum resection and aberrant left subclavian artery reimplantation at the time of CVR repair will require reintervention in the future.

We report the case of a 72-year-old woman with limited systemic sclerosis, who was initially diagnosed with systemic sclerosis-related pulmonary arterial hypertension. However, after introduction of sildenafil and bosentan, the patient developed acute pulmonary oedema, and findings from complementary exams were suggestive of PVOD.
