Risk of Bronchiolitis Obliterans Syndrome Is Twice as High in Cyclosporine Treated Patients in Comparison to Tacrolimus 3 Years after Lung Transplantation: Results of a Prospective Randomized International Trial of 248 Patients

Purpose: In this prospective randomized study efficacy and safety of two immunosuppressive regimens (Tac, MMF, Steroids vs. CsA, MMF, Steroids) after Lung Transplantation were compared. Primary objective was the incidence of bronchiolitis obliterans syndrome (BOS). Secondary objectives were incidence of acute rejection and infection, survival and adverse events. 248 patients with a complete 3 year follow-up were included in the analysis. Methods and Materials: Patients were randomized to treatment group A: Tac (0.01-0.03 mg/kg/d iv-0.05-0.3 mg/kg/d po) or B: CsA (1-3 mg/kg/d iv-2-8 mg/kg/d po). MMF dose was1-4 mg/d in both groups. No induction therapy was given. Patients were stratified for cystic fibrosis. Intention to treat analysis was performed in patients who were switched to a different immunosuppressive regimen. Results: 3 of 123 Tac patients and 41 of 125 CsA patients were switched to another immunosuppressive regimen and were analyzed as intention to treat. Three year follow-up data of the complete patient cohort were included in this final analysis. Groups showed no difference in demographic data. Kaplan Meier analysis revealed significantly less BOS in Tac treated patients (p=0.033, log rank test, pooled over strata). Cox regression showed a twice as high risk for BOS in the CsA group (factor 2.003). Incidence of acute rejection was 67.5% (Tac) and 75.2% (CsA) (p=0.583). One- and 3-year-survival-rates were not different (85.4% Tac vs. 88.8% CsA, and 80.5% Tac vs. 83.2% CsA, p=n.s.). Incidence of infections and renal failure was similar (p=n.s.). Conclusions: Tac significantly reduced the risk for BOS after 3 years in this intention to treat analysis. Both regimens have a good immunosuppressive potential and offer a similar safety profile with excellent one and three year survival rates. Acute rejection rates were similar in both groups. Incidence of infections and renal failure showed no difference.

GLUT4, AMP kinase, but not the insulin receptor, are required for hepatoportal glucose sensor-stimulated muscle glucose utilization.

Recent evidence suggests the existence of a hepatoportal vein glucose sensor, whose activation leads to enhanced glucose use in skeletal muscle, heart, and brown adipose tissue. The mechanism leading to this increase in whole body glucose clearance is not known, but previous data suggest that it is insulin independent. Here, we sought to further determine the portal sensor signaling pathway by selectively evaluating its dependence on muscle GLUT4, insulin receptor, and the evolutionarily conserved sensor of metabolic stress, AMP-activated protein kinase (AMPK). We demonstrate that the increase in muscle glucose use was suppressed in mice lacking the expression of GLUT4 in the organ muscle. In contrast, glucose use was stimulated normally in mice with muscle-specific inactivation of the insulin receptor gene, confirming independence from insulin-signaling pathways. Most importantly, the muscle glucose use in response to activation of the hepatoportal vein glucose sensor was completely dependent on the activity of AMPK, because enhanced hexose disposal was prevented by expression of a dominant negative AMPK in muscle. These data demonstrate that the portal sensor induces glucose use and development of hypoglycemia independently of insulin action, but by a mechanism that requires activation of the AMPK and the presence of GLUT4.

Is pretreatment with Beta-blockers beneficial in patients with acute coronary syndrome?

OBJECTIVES: The role of beta-blockers in the treatment of hypertension is discussed controversially and the data showing a clear benefit in acute coronary syndromes (ACS) were obtained in the thrombolysis era. The goal of this study was to analyze the role of pretreatment with beta-blockers in patients with ACS. METHODS: Using data from the Acute Myocardial Infarction in Switzerland (AMIS Plus) registry, we analyzed outcomes of patients with beta-blocker pretreatment in whom they were continued during hospitalization (group A), those without beta-blocker pretreatment but with administration after admission (group B) and those who never received them (group C). Major adverse cardiac events defined as composed endpoint of re-infarction and stroke (during hospitalization) and/or in-hospital death were compared between the groups. RESULTS: A total of 24,709 patients were included in the study (6,234 in group A, 12,344 in group B, 6,131 in group C). Patients of group B were younger compared to patients of group A and C (62.5, 67.6 and 68.4, respectively). In the multivariate analysis, odds ratio for major adverse cardiac events was 0.59 (CI 0.47-0.74) for group A and 0.66 (CI 0.55-0.83) for group B, while group C was taken as a reference. CONCLUSIONS: beta-Blocker therapy is beneficial in ACS and they should be started in those who are not pretreated and continued in stable patients who had been on chronic beta-blocker therapy before.

Oxygen uptake during early cardiogenesis of the chick.

Oxidative metabolism of the isolated embryonic heart of the chick has been determined using a spectrophotometric technique allowing global as well as localized micromeasurements of the O2 uptake. Entire hearts, excised from embryos of 10 somites (primordia fused, stage 10 HH) and 40 somites (S shaped, stage 20 HH) were placed in a special chamber under controlled metabolic conditions where they continued to beat spontaneously and regularly. During the 32 h of development, the O2 consumption of the whole heart increased from 0.9 +/- 0.1 to 5.3 +/- 0.8 nmol O2/h. These values corrected for protein content were, however, comparable (0.45 nmol O2.h-1.micrograms-1). At stage 10-12, the O2 uptake varied along the cardiac tube (from 0.74 to 1.0 nmol O2.h-1.mm-2). From stage 10 to 20, the O2 uptake per unit area of ventricle wall increased from 0.7 +/- 0.2 to 1.8 +/- 0.2 nmol O2.h-1.mm-2, and the O2 uptake per myocardial volume during one cardiac cycle varied from 7 to 2.5 nmol O2/cm3. These results indicate that, despite an intense morphogenesis, the cardiac tissue has a rather low and stable oxidative metabolism, although the O2 requirement of the whole heart increases significantly. Moreover, the normalized suprabasal aerobic energy expenditure decreases throughout early cardiogenesis. The functional integrity of the isolated embryonic heart combined with the experimental possibilities of the microtechnique make the preparation appropriate for studying the changes in cardiac metabolism during development.

Beyond the usual suspects: positive attitudes towards positive symptoms is associated with medication noncompliance in psychosis.

Antipsychotic medication represents the treatment of choice in psychosis according to clinical guidelines. Nevertheless, studies show that half to almost three-quarter of all patients discontinue medication with antipsychotics after some time, a fact which is traditionally ascribed to side-effects, mistrust against the clinician and poor illness insight. The present study investigated whether positive attitudes toward psychotic symptoms (ie, gain from illness) represent a further factor for medication noncompliance. An anonymous online survey was set up in order to prevent conservative response biases that likely emerge in a clinical setting. Following an iterative selection process, data from a total of 113 patients with a likely diagnosis of schizophrenia and a history of antipsychotic treatment were retained for the final analyses (80%). While side-effect profile and mistrust emerged as the most frequent reasons for drug discontinuation, 28% of the sample reported gain from illness (eg, missing voices, feeling of power) as a motive for noncompliance. At least every fourth patient reported the following reasons: stigma (31%), mistrust against the physician/therapist (31%), and rejection of medication in general (28%). Approximately every fifth patient had discontinued antipsychotic treatment because of forgetfulness. On average, patients provided 4 different explanations for noncompliance. Ambivalence toward symptoms and treatment should thoroughly be considered when planning treatment in psychosis. While antipsychotic medication represents the evidence-based cornerstone of the current treatment in schizophrenia, further research is needed on nonpharmacological interventions for noncompliant patients who are willing to undergo intervention but refuse pharmacotherapy.

Position of indapamide , a diuretic with vasorelaxant activities, in antihypertensive therapy.

Introduction: Diuretics play a pivotal role in the management of hypertension. A large experience has been accumulated with indapamide , a long-acting thiazide-like diuretic that lowers blood pressure (BP) primarily through its natriuretic diuretic effect. Some of its long-term antihypertensive efficacy may be due to calcium antagonist-like vasorelaxant activities. Indapamide has protecting effects in a variety of conditions associated with high cardiovascular risk, such as diabetes, left ventricular hypertrophy, nephropathy and stroke. It is highly effective in lowering BP, whether given alone or in combination. Indapamide is well tolerated and has the advantage of having no adverse impact on glucose and lipid metabolism. Today, thiazide-like diuretics are regarded more and more as preferred drugs, when diuretic therapy is required to lower BP. Areas covered: The aim of this paper is to review the experience accumulated with indapamide. It is limited to clinical studies that are relevant for the everyday management of hypertensive patients, whether or not they exhibit cardiovascular or renal disease. Expert opinion: Indapamide, because of its well-documented beneficial effects on cardiovascular and renal outcomes, represents a safe and valuable option for treating patients with high BP. There is, however, still room for new trials evaluating the combination of this diuretic with other types of antihypertensive drugs, in particular a calcium antagonist such as amlodipine. There is also the need to compare the indapamide-perindopril and indapamide-amlodipine combinations, in terms of antihypertensive efficacy, tolerability and effects on target organ damage and, ideally, on cardiovascular mortality.

Predicting outcome after acute basilar artery occlusion based on admission characteristics.

OBJECTIVE: To develop a simple prognostic model to predict outcome at 1 month after acute basilar artery occlusion (BAO) with readily available predictors. METHODS: The Basilar Artery International Cooperation Study (BASICS) is a prospective, observational, international registry of consecutive patients who presented with an acute symptomatic and radiologically confirmed BAO. We considered predictors available at hospital admission in multivariable logistic regression models to predict poor outcome (modified Rankin Scale [mRS] score 4-5 or death) at 1 month. We used receiver operator characteristic curves to assess the discriminatory performance of the models. RESULTS: Of the 619 patients, 429 (69%) had a poor outcome at 1 month: 74 (12%) had a mRS score of 4, 115 (19%) had a mRS score of 5, and 240 (39%) had died. The main predictors of poor outcome were older age, absence of hyperlipidemia, presence of prodromal minor stroke, higher NIH Stroke Scale (NIHSS) score, and longer time to treatment. A prognostic model that combined demographic data and stroke risk factors had an area under the receiver operating characteristic curve (AUC) of 0.64. This performance improved by including findings from the neurologic examination (AUC 0.79) and CT imaging (AUC 0.80). A risk chart showed predictions of poor outcome at 1 month varying from 25 to 96%. CONCLUSION: Poor outcome after BAO can be reliably predicted by a simple model that includes older age, absence of hyperlipidemia, presence of prodromal minor stroke, higher NIHSS score, and longer time to treatment.

Low-dose intradermal versus intramuscular trivalent inactivated seasonal influenza vaccine in lung transplant recipients.

BACKGROUND: In this study we compared the immunogenicity of influenza vaccine administered intradermally to the standard intramuscular vaccination in lung transplant recipients. METHODS: Patients were randomized to receive the trivalent inactivated seasonal 2008-9 influenza vaccine containing either 6 μg (intradermal) or 15 μg (intramuscular) of hemagglutinin per viral strain. Immunogenicity was assessed by measurement of geometric mean titer of antibodies using the hemagglutination-inhibition (HI) assay. Vaccine response was defined as a 4-fold or higher increase of antibody titers to at least one vaccine antigen. RESULTS: Eighty-five patients received either the intradermal (n = 41) or intramuscular (n = 44) vaccine. Vaccine response was seen in 6 of 41 patients (14.6%) in the intradermal vs 8 of 43 (18.6%) in the intramuscular group (p = 0.77). Seroprotection (HI ≥1:32) was 39% for H1N1, 83% for H3N2 and 29% for B strain in the intradermal group vs 28% for H1N1, 98% for H3N2 and 58% for B strain in the intramuscular group (p = 0.36 for H1N1, p = 0.02 for H3N2, p < 0.01 for B). Mild adverse events were seen in 44% of patients in the intradermal group and 34% in the intramuscular group (p = 0.38). CONCLUSIONS: Immunogenicity of the 2008-9 influenza vaccine given intradermally or intramuscularly was overall poor in lung transplant recipients. Novel strategies for influenza vaccination in this population are needed.

Étude de la fonction de GLUT8 sur un modèle de souris "knock-out"

Résumé GLUT8 est la première des nouvelles isoformes des GLUT récemment identifiés. Il est fortement exprimé dans les testicules et plus faiblement dans les blastocystes, le cerveau, particulièrement au niveau de l'hippocampe, et le coeur. En conditions basales, il est retenu dans un compartiment intracellulaire. Si on l'exprime en surface cellulaire, par la mutation du motif d'internalisation dileucine, il transporte le glucose avec une bonne affinité. Dans le but d'étudier sa fonction au niveau de l'organisme, nous avons créé un modèle de knock out conditionnel, en entourant le dernier exon du gène de GLUT8 par deux sites loxP. En croisant nos souris avec une souche de souris transgénique exprimant la cre-recombinase dans les cellules de la lignée germinale, nous avons généré un modèle de souris portant la délétion totale de GLUT8 de manière constitutionnelle. Les statistiques effectuées sur les premières naissances indiquent qu'une partie des souris knock out ne survit pas, suggérant un rôle de GLUT8 au niveau du développement embryonnaire. Les souris qui ont survécu ne présentent toutefois pas d'anomalies durant la croissance et sont fertiles. Elles ont des taux de glucose et d'insuline sanguins normaux. Au niveau cérébral, la structure de l'hippocampe n'est pas modifiée par la suppression de GLUT8, cependant, les souris GLUT8-/- présentent une prolifération cellulaire augmentée dans le gyrus denté. Cette augmentation de division cellulaire pourrait être la réponse adaptée à une éventuelle augmentation de la mort cellulaire au niveau de l'hippocampe. Elles ne semblent toutefois pas présenter de défauts cognitifs majeurs dans le bassin de Morris en conditions normales. Toutefois, en conditions de jeûne, elles tendent à une meilleure mémorisation à court terme. Les études morphologiques et histologiques au niveau cardiaque n'ont pas révélé de d'hypertrophie au niveau ventriculaire. La stimulation de la contraction à l'isoprotérénol n'a pas mis en évidence de défaut d'adaptation des coeurs GLUT8-/-. Cependant l'analyse fonctionnelle par électrocardiogramme, en conditions basales, a montré une augmentation de la durée de l'onde P, suggérant un défaut dans la dépolarisation des oreillettes. Nos résultats indiquent que GLUT8 ne joue pas un rôle prédominant dans la survie et la fonction basale des souris. Il pourrait jouer un rôle plus important dans des situations stressantes pour l'organisme, comme l'hypoglycémie ou les conditions d'ischémie qui induiraient son expression à la membrane plasmique et stimuleraient le captage du glucose. Abstract GLUT8 was the first of the recently identified isoform of the GLUT family proteins. It is strongly expressed in the testis. It is also found at a lower level in the blastocyst, in heart and in the brain. Under basal conditions, it is retained in the intracellular compartment, but when the internalization motif dileucine is mutated, GLUT8 translocates to the plasma membrane and transports glucose with a relatively high affinity. To study its function in vivo, we created a conditional knock out mouse model. To do so, we targeted the last exon of the GLUT8 gene with two loxP sites. We then crossed these mice with a transgenic model expressing the cre-recombinase in the gem' line to generate a constitutional total knock out mouse. The statistics made on the first breedings showed that some of the knock out mice do not survive, suggesting a role of GLUT8 in the embryonic development. Conversely mice who survive do not show developmental defects and they are fertile with normal glucose and insulin blood levels. In the brain, the general structure of the hippocampus is not modified by the deletion of GLUT8. However, GLUT8-/- mice show an increase in the cell proliferation in the dentate gyms. This cell proliferation could be due to an increase in the cell death in the hippocampus. When tested in the morris water maze, these mice do not show any cognitive defects in the basal conditions, but they have a tendency to learn better in fasted conditions. The morphological and histological studies made at the heart level did not show any cardiac hypertrophy in the ventricles. The stimulation with isoproterenol did not show any adaptation defects in the GLUT8-/- hearts. However, the functional analysis made in basal conditions with the electrocardiogram showed an increase in the P wave length, suggesting a defect in the atrial depolarization in the knock out mice. Overall, our results show that GLUT8 does not play an important role in the basal general functions in the mice, but might play a more important role during whole organism stress. Hypoglycaemia or ischemia, for example could stimulate the GLUT8 translocation to the plasma membrane to increase specifically glucose uptake. Résumé tout public Les différentes cellules de l'organisme possèdent des propriétés particulières, qui leur permettent de maintenir les fonctions de l'organe auquel elles appartiennent. La membrane plasmique qui les délimite sélectionne les substances qui vont pénétrer à l'intérieur de la cellule et permet ainsi de maintenir un environnement interne constant. Le glucose est une source d'énergie importante pour la cellule et doit pouvoir pénétrer à l'intérieur de la cellule. Il utilise pour cela des protéines de transport qui le feront passer de part et d'autre de la membrane. Les protéines de la famille des GLUT (pour GLUcose Transporter) possèdent cette capacité. GLUT8 est un membre de la famille des GLUT identifié récemment. Il possède la capacité de transporter le glucose quand il se présente à la surface de la cellule. Il est principalement exprimé dans les testicules, dans le coeur et le cerveau et durant le développement embryonnaire. Son rôle n'est toutefois pas encore défini. Ce travail consiste à étudier la fonction de GLUT8 au niveau de l'organisme entier. Nous avons créé un modèle de souris dans lesquelles l'expression de GLUT8 a été supprimée pour mettre en évidence son importance dans le maintien de l'intégrité des fonctions du corps. Les observations effectuées sur les souris qui n'expriment plus GLUT8 nous indiquent que leurs cellules prolifèrent plus vite au niveau de l'hippocampe. L'hippocampe est une structure située dans le cerveau qui est impliquée dans les phénomènes d'apprentissage. Les souris qui ont été testées dans des tâches d'apprentissage n'ont malgré cela pas montré une amélioration de la mémorisation. Dans le coeur, la suppression de GLUT8 semble présenter un défaut quand on mesure l'activité électrique du coeur par électrocardiogramme. Toutefois, ils fonctionnent normalement et ne présentent pas de défauts morphologiques en conditions normales. Les expériences effectuées sur les modèles de souris indiquent que GLUT8 ne jouerait pas un rôle prédominant dans le fonctionnement normal du corps. Il pourrait exercer sa fonction dans des situations plus particulières comme l'hypoglycémie, où il permettrait une meilleure capacité à transporter le glucose dans les cellules.

FGF-2 controls the differentiation of resident cardiac precursors into functional cardiomyocytes.

Recent evidence suggests that the heart possesses a greater regeneration capacity than previously thought. In the present study, we isolated undifferentiated precursors from the cardiac nonmyocyte cell population of neonatal hearts, expanded them in culture, and induced them to differentiate into functional cardiomyocytes. These cardiac precursors appear to express stem cell antigen-1 and demonstrate characteristics of multipotent precursors of mesodermal origin. Following infusion into normal recipients, these cells home to the heart and participate in physiological and pathophysiological cardiac remodeling. Cardiogenic differentiation in vitro and in vivo depends on FGF-2. Interestingly, this factor does not control the number of precursors but regulates the differentiation process. These findings suggest that, besides its angiogenic actions, FGF-2 could be used in vivo to facilitate the mobilization and differentiation of resident cardiac precursors in the treatment of cardiac diseases.

Peroxisome proliferator-activated receptor beta/delta as a therapeutic target for metabolic diseases.

The peroxisome proliferator-activated receptor (PPAR) family comprises three distinct isotypes: PPARalpha, PPARbeta/delta and PPARgamma. PPARs are nuclear hormone receptors that mediate the effects of fatty acids and their derivatives at the transcriptional level. Until recently, the characterisation of the important role of PPARalpha in fatty acid oxidation and of PPARgamma in lipid storage contrasted with the sparse information concerning PPARbeta/delta. However, evidence is now emerging for a role of PPARbeta/delta in tissue repair and energy homeostasis. Experiments with tissue-specific overexpression of PPARbeta/delta or treatment of mice with selective PPARbeta/delta agonists demonstrated that activation of PPARbeta/delta in vivo increases lipid catabolism in skeletal muscle, heart and adipose tissue and improves the serum lipid profile and insulin sensitivity in several animal models. PPARbeta/delta activation also prevents the development of obesity and improves cholesterol homeostasis in obesity-prone mouse models. These new insights into PPARbeta/delta functions suggest that targeting PPARbeta/delta may be helpful for treating disorders associated with the metabolic syndrome. Although these perspectives are promising, several independent and contradictory reports raise concerns about the safety of PPARbeta/delta ligands with respect to tumourigenic activity in the gut. Thus, it appears that further exploration of PPARbeta/delta functions is necessary to better define its potential as a therapeutic target.

Population pharmacokinetics of ganciclovir in solid-organ transplant recipients receiving oral valganciclovir.

Valganciclovir (VGC) is an oral prodrug of ganciclovir (GCV) recently introduced for prophylaxis and treatment of cytomegalovirus infection. Optimal concentration exposure for effective and safe VGC therapy would require either reproducible VGC absorption and GCV disposition or dosage adjustment based on therapeutic drug monitoring (TDM). We examined GCV population pharmacokinetics in solid organ transplant recipients receiving oral VGC, including the influence of clinical factors, the magnitude of variability, and its impact on efficacy and tolerability. Nonlinear mixed effect model (NONMEM) analysis was performed on plasma samples from 65 transplant recipients under VGC prophylaxis or treatment. A two-compartment model with first-order absorption appropriately described the data. Systemic clearance was markedly influenced by the glomerular filtration rate (GFR), patient gender, and graft type (clearance/GFR = 1.7 in kidney, 0.9 in heart, and 1.2 in lung and liver recipients) with interpatient and interoccasion variabilities of 26 and 12%, respectively. Body weight and sex influenced central volume of distribution (V(1) = 0.34 liter/kg in males and 0.27 liter/kg in females [20% interpatient variability]). No significant drug interaction was detected. The good prophylactic efficacy and tolerability of VGC precluded the demonstration of any relationship with GCV concentrations. In conclusion, this analysis highlights the importance of thorough adjustment of VGC dosage to renal function and body weight. Considering the good predictability and reproducibility of the GCV profile after treatment with oral VGC, routine TDM does not appear to be clinically indicated in solid-organ transplant recipients. However, GCV plasma measurement may still be helpful in specific clinical situations.

Clinical Proton MR Spectroscopy in Central Nervous System Disorders.

A large body of published work shows that proton (hydrogen 1 [(1)H]) magnetic resonance (MR) spectroscopy has evolved from a research tool into a clinical neuroimaging modality. Herein, the authors present a summary of brain disorders in which MR spectroscopy has an impact on patient management, together with a critical consideration of common data acquisition and processing procedures. The article documents the impact of (1)H MR spectroscopy in the clinical evaluation of disorders of the central nervous system. The clinical usefulness of (1)H MR spectroscopy has been established for brain neoplasms, neonatal and pediatric disorders (hypoxia-ischemia, inherited metabolic diseases, and traumatic brain injury), demyelinating disorders, and infectious brain lesions. The growing list of disorders for which (1)H MR spectroscopy may contribute to patient management extends to neurodegenerative diseases, epilepsy, and stroke. To facilitate expanded clinical acceptance and standardization of MR spectroscopy methodology, guidelines are provided for data acquisition and analysis, quality assessment, and interpretation. Finally, the authors offer recommendations to expedite the use of robust MR spectroscopy methodology in the clinical setting, including incorporation of technical advances on clinical units. © RSNA, 2014 Online supplemental material is available for this article.

How to manage the left subclavian artery during endovascular stenting of the thoracic aorta.

We performed a systematic review of the literature to establish whether revascularisation of the left subclavian territory is necessary when this artery is covered by a stent. We retrieved data from 99 studies incorporating 4906 patients. Incidences of left-arm ischaemia (0.0% vs 9.2%, p=0.002) and stroke (4.7% vs 7.2%, p<0.001) were significantly less following revascularisation, although mortality (10.5% vs 3.4%, p=0.032) and endoleak incidence (25.8% vs 12.6%, p=0.008) were increased. No significant differences in spinal-cord ischaemia were seen. Revascularisation may reduce downstream ischaemic complications but can cause significant risk. Indications must be carefully considered on an individual patient basis.

Postmortem imaging of sudden cardiac death

Postmortem imaging is increasingly used in forensic practice in cases of natural deaths related to cardiovascular diseases, which represent the most common causes of death in developed countries. While radiological examination is generally considered to be a good complement for conventional autopsy, it was thought to have limited application in cardiovascular pathology. At present, multidetector computed tomography (MDCT), CT angiography, and cardiac magnetic resonance imaging (MRI) are used in postmortem radiological investigation of cardiovascular pathologies. This review presents the actual state of postmortem imaging for cardiovascular pathologies in cases of sudden cardiac death (SCD), taking into consideration both the advantages and limitations. The radiological evaluation of ischemic heart disease (IHD), the most frequent cause of SCD in the general population of industrialized countries, includes the examination of the coronary arteries and myocardium. Postmortem CT angiography (PMCTA) is very useful for the detection of stenoses and occlusions of coronary arteries but less so for the identification of ischemic myocardium. MRI is the method of choice for the radiological investigation of the myocardium in clinical practice, but its accessibility and application are still limited in postmortem practice. There are very few reports implicating postmortem radiology in the investigation of other causes of SCD, such as cardiomyopathies, coronary artery abnormalities, and valvular pathologies. Cardiomyopathies representing the most frequent cause of SCD in young athletes cannot be diagnosed by echocardiography, the most widely available technique in clinical practice for the functional evaluation of the heart and the detection of cardiomyopathies. PMCTA and MRI have the potential to detect advanced stages of diseases when morphological substrate is present, but these methods have yet to be sufficiently validated for postmortem cases. Genetically determined channelopathies cannot be detected radiologically. This review underlines the need to establish the role of postmortem radiology in the diagnosis of SCD.
