Cardiac magnetic resonance imaging of arrhythmogenic cardiomyopathy: evolving diagnostic perspectives.

Arrhythmogenic cardiomyopathy (ACM) is a genetically determined heart muscle disease characterized by fibro-fatty myocardial replacement, clinically associated with malignant ventricular arrhythmias and sudden cardiac death. Originally described a disease with a prevalent right ventricular (RV) involvement, subsequently two other phenotypes have been recognized, such as the left dominant and the biventricular phenotypes, for which a recent International Expert consensus document provided upgrade diagnostic criteria (the 2020 "Padua Criteria"). In this novel workup for the diagnosis of the entire spectrum of phenotypic variants of ACM, including left ventricular (LV) variants, cardiac magnetic resonance (CMR) has emerged as the cardiac imaging technique of choice, due to its capability of detailed morpho-functional and tissue characterization evaluation of both RV and LV. In this review, the key role of CMR in the diagnosis of ACM is outlined, including the supplemental value for the characterization of the disease variants. An ACM-specific CMR study protocol, as well as strengths and weaknesses of each imaging technique, is also provided. KEY POINTS: • Arrhythmogenic cardiomyopathy includes three different phenotypes: dominant right, biventricular, and dominant left. • In 2020, diagnostic criteria have been updated and cardiac magnetic resonance has emerged as the cardiac imaging technique of choice. • This aim of this review is to provide an update of the current state of art regarding the use of CMR in ACM, with a particular focus on novel diagnostic criteria, CMR protocols, and prognostic significance of CMR findings in ACM.

Coronary artery calcium score: we know where we are but not where we may be.

Cardiac computed tomography angiography (CCTA) has emerged as a cost-effective and time-saving technique for excluding coronary artery disease. One valuable tool obtained by CCTA is the coronary artery calcium (CAC) score. The use of CAC scoring has shown promise in the risk assessment and stratification of cardiovascular disease. CAC scores can be complemented by plaque analysis to assess vulnerable plaque characteristics and further refine risk assessment. This paper aims to provide a comprehensive understanding of the value of the CAC as a prognostic tool and its implications for patient risk assessment, treatment strategies, and outcomes. CAC scoring has demonstrated superior ability in stratifying patients, especially asymptomatic individuals, compared to traditional risk factors and scoring systems. The main evidence suggests that individuals with a CAC score of 0 have a good long-term prognosis, while an elevated CAC score is associated with increased cardiovascular risk. Finally, the clinical power of CAC scoring and the development of new models for risk stratification could be enhanced by machine learning algorithms.

Psoriasis and imaging progression in early axial spondyloarthritis: results from a 48-month follow-up (Italian arm of SPACE study).

OBJECTIVES: To assess the influence of psoriasis on spinal/pelvic radiographic progression and MRI features in early-stage axial spondyloarthritis (axSpA). METHODS: Analysis of baseline data from the Italian SPACE cohort, including patients with chronic back pain (CBP; duration ≥3 months and ≤2 years; onset <45 years) was performed. Patients underwent a diagnostic work-up, including MRI and X-rays of the sacroiliac joints (SIJ), to establish diagnosis of axSpA (Assessment of Spondyloarthritis International Society criteria). Clinical features, disease activity and functional indices, imaging were collected at baseline and yearly during 48 months. Spinal and SIJ X-rays and MRIs were scored by two readers following Spondyloarthritis Research Consortium of Canada score, Stoke Ankylosing Spondylitis Spinal Score System modified by Creemers and modified New York criteria. Characteristics of axSpA patients with/without psoriasis were compared over time with descriptive statistics; multivariate logistic regression model was constructed to assess predictors of spinal/pelvic radiographic progression. RESULTS: Eighty-eight patients had axSpA (84.1% non-radiographic; 15.9% radiographic); 36.4% had psoriasis. Patients with psoriasis were older; less frequently had HLA-B27+ and radiographic sacroiliitis with unilateral/asymmetric pattern and more signs of spondylitis. Functional and disease activity indices decreased with slightly higher BASDAI and BASFI in axSpA with psoriasis. All patients showed slight spinal/pelvic radiographic progression. Patients without psoriasis showed increased sacroiliitis progression and low-grade spinal progression. More inflammatory corner lesions on cervical/thoracic MRI-spine were observed in patients with psoriasis. A significant downtrend of SPARCC SIJ/spine scores in all patients was found. Psoriasis was a predictor of increased spinal progression (odds ratio = 0.18; 95% CI: 0.04, 0.78). CONCLUSIONS: Psoriasis was associated with distinct axSpA features, increased spinal radiographic progression and low-grade radiographic sacroiliitis.

It's not over until it's over: the chameleonic behavior of COVID-19 over a six-day period.

The current global outbreak of COVID-19 represents a major challenge in terms of epidemiology, contagiousness, treatment, as well as clinical and radiological behavior of this disease. Radiological imaging plays a key role in the diagnostic process and during the monitoring of the clinical conditions especially of patients with severe symptoms. According to the preliminary data collected in our tertiary center, we have documented a peculiar behavior in patients requiring endotracheal intubation who underwent seriate chest X-rays. In fact, the radiological pattern of COVID-19 patients may worsen despite a prompt amelioration after the onset of mechanical ventilation. Thus, according to our initial evidence, we recommend to perform seriate chest X-rays in the days following the onset of mechanical ventilation even if the immediate monitoring suggests an improvement. Studies on a larger scale are necessary to fully assess the findings at chest radiographs of critical, mechanically ventilated patients and their correlation with the long-term outcome.

Radiological management of COVID-19: structure your diagnostic path to guarantee a safe path.

The current COVID-19 outbreak is requiring a tremendous effort not only regarding the diagnostic and therapeutic approach but also in terms of global management of the delivered care. Hospital administrations had to provide a prompt response to a rapidly evolving emergency characterized by the necessity of giving access to an enormous number of infected patients, guaranteeing appropriate care to patients in need of other types of treatment, and simultaneously preserving the well-being of healthcare providers. To optimize the diagnostic pathway during the current COVID-19 outbreak, the hospital administration of our tertiary center applied a highly structured framework assigning specific tasks to the different units composing the Department of Imaging. In particular, since the beginning of the pandemic, a mobile CT scanner in a truck was rented and became operative for all patients with a confirmed diagnosis of COVID-19 and another CT was assigned for all suspected cases. The success and efficacy of the management applied by our administration is demonstrated by the fact that during the outbreak, the radiological workflow was never interrupted. In fact, despite the national lockdown only a 29.3% decrease of CT scans occurred compared to the previous year. Moreover, none of the healthcare providers of the Department contracted the infection at work. Thus, according to the experience gained in our center, we recommend to all hospital administrations facing the COVID-19 outbreak to promptly adapt their resources, creating precise and safe pathways for their diagnostic units.

US-guided percutaneous treatment and physical therapy in rotator cuff calcific tendinopathy of the shoulder: outcome at 3 and 12 months.

OBJECTIVES: To monitor the results of ultrasound (US)-guided percutaneous treatment of calcific tendinopathy of the shoulder at 12 months (T12) after treatment (T0). To verify the possible relations between some pre- and post-procedural variables with the clinical outcome at T12. METHODS: Forty-seven patients (26 female and 21 male) were enrolled in the study. Patients' approval and written informed consent were obtained. Symptoms were assessed by Constant Shoulder Score (CSS) at T0 and T12. Thirty of these also underwent a CSS control at 3 months (T3). The treatment efficacy was statistically tested for relation with location and type of calcification, characteristics of the tendon and subdeltoid bursa, impingement, and rehabilitation treatments. RESULTS: There was a significant increase in the average CSS value between T0 and T12 (40.7 vs. 75.3). The variables analysed did not show a statistically significant effect on the outcome at T12. A link was noticed only between patients' increasing age and score improvement, particularly among female subjects. CONCLUSION: US-guided treatment of calcific tendonitis is a viable therapeutic option. No pre- or intra-procedural parameters emerged which might help in predicting the outcome, apart from patients' needs in everyday life. KEY POINTS: • US-guided tcreatment of shoulder calcific tendinopathy is an excellent therapeutic option • Long-term results seem greatly affected by patients' features and needs in everyday life • No proven pre- or intra-procedural parameters emerged that might predict the outcome.

Thinning of compact layer and systolic dysfunction in isolated left ventricular non-compaction: A cardiac magnetic resonance study.

BACKGROUND: The Petersen' index reflects an excess of myocardial trabeculation which is not a specific morpho-functional feature of left ventricular non-compaction (LVNC) cardiomyopathy, but a "phenotypic trait" even observed in association with other myocardial diseases and over-loading conditions. The present study was designed to evaluate the relation between a critical thinning of compact layer and the development of systolic dysfunction and LVNC cardiomyopathy. METHODS: We compared CMR morpho-functional features and measurements of LV wall thickness using a 17 segment model of a cohort of patients fulfilling the Petersen criterion for LVNC with LV systolic dysfunction versus those of a cohort of age- and sex-matched controls with LVNC and preserved LV systolic function. All the study patients had an "isolated" LVNC defined as positive Petersen criterion in the absence of other diseases such as hypertrophic and dilated cardiomyopathy, valvular heart disease, or congenital heart disease and over-loading conditions. RESULTS: he study population included 33 patients with "isolated" LVNC: 11 consecutive index patients with a reduced LV ejection fraction (LVNCrEF) and 22 controls with a preserved LVEF (LVNCpEF). The compact myocardial layer was thinner in patients with LVNCrEF than in those with LVNCpEF patients, both in mid-ventricular and apical LV segments. On linear regression analysis, there was a linear correlation between median thickness of mid-ventricular free wall segments and left ventricular ejection fraction (r = 0.51, p = 0.005). On the ROC curves analysis, ≥2 segments with a compact myocardial layer <5 mm in the free wall mid-ventricular segments showed the best accuracy for reduced LVEF (100% sensitivity and 60% specificity; AUC 0.81, p < 0.01). The negative predictive value for LV systolic dysfunction of <2 free wall mid ventricular segments <5 mm was 100%. On quantitative analysis, the mass of papillary muscles was lower in patients with LVNCrEF [1.2 (0.8-1.4) versus 1.6 (1.1-1.8) g/mq; p = 0.08]. CONCLUSIONS: A thinned compact layer of mid-ventricular segments of the LV free wall was associated with a reduced systolic function and "isolated" LVNC cardiomyopathy.

Micro-CT evaluation of morphological degenerative features of sterno-clavicular joint for age-at-death estimation in forensic anthropology - A qualitative analysis.

The analysis of the sternoclavicular joint holds significant importance in forensic anthropology, especially through the evaluation of medial clavicular ossification stage, which, however, is helpful only in subjects younger than 30 years of age. Given this limitation, the aim of the present work was to examine, through micro-CT, the surface of sternoclavicular joints of deceased individuals across various age groups, aiming to identify age-related degenerative changes applicable to age estimation in adults over 30 years old. A total of 41 deceased subjects were categorized into three age groups (20-39 years; 40-59 years; ≥60 years) for the analysis. Degenerative morphological features on both clavicular and sternal articular surfaces, including topography, porosity, and presence of osteophytes, were evaluated using a composite scoring system based on a modified "Falys-Prangle method.", which assigns to each parameter specific score ranges: 1-3 for surface topography (smooth, slightly irregular, markedly irregular), 1-6 for porosity (absent, micro- and macroporosity for <50 % or >50 % of surface, surface breakdown), 1-3 for osteophytes (absent, present, not evaluable). The findings revealed a positive correlation between degenerative morphological features and age for both clavicular (rs = 0.719) and sternal articular surfaces (rs = 0.750). Additionally, the combined assessment of the clavicle and sternum, or the evaluation of the clavicle alone, exhibited better differentiation among the three age groups. The micro-CT evaluation of degenerative alterations affecting the sternoclavicular joint proves to be a reliable and efficient method for age estimation in adults.

Redefining CAV surveillance strategies: Benefits of CCTA vs. ICA.

BACKGROUND: Cardiac allograft vasculopathy (CAV) assessment post-heart transplantation (HT) typically relies on invasive coronary angiography (ICA). However, cardiac computed tomography angiography (CCTA) is emerging as a promising alternative due to its potential benefits in economic, safety, and logistical aspects. This study aimed to evaluate the impact of a CCTA program on these aspects in CAV surveillance post-HT. METHODS: A retrospective single-center study was conducted between March 2021 and February 2023, involving HT patients who underwent either CCTA or ICA. RESULTS: Among 260 patients undergoing CAV surveillance, 115 (44.2%) patients underwent CCTA, and 145 (55.8%) patients underwent ICA. The CCTA group showed incurred lower overall costs (p â€‹< â€‹0.0001) and shorter hospitalization times (p â€‹< â€‹0.0001) compared to the ICA group. In terms of safety, CCTA surveillance required significantly lower contrast volumes (p â€‹< â€‹0.0001) and lower effective doses (p â€‹= â€‹0.03). CONCLUSION: CCTA emerges as a safe and cost-effective non-invasive alternative for CAV surveillance post-HT, outperforming ICA in terms of safety, logistical aspects, and economic burden.

Determinants of Ventricular Arrhythmias in Mitral Valve Prolapse.

BACKGROUND: Mitral valve prolapse (MVP) may be associated with ventricular arrhythmias (VA) even in the absence of significant valvular regurgitation. Curling, mitral annulus disjunction (MAD) and myocardial fibrosis (late gadolinium enhancement [LGE]) may account for arrhythmogenesis. OBJECTIVES: This study investigated the determinants of VA in patients with MVP without significant regurgitation. METHODS: This study included 108 patients with MVP (66 female; median age: 48 years) without valve regurgitation. All patients underwent 12-lead electrocardiography, 12-lead 24-hour electrocardiographic Holter monitoring, exercise stress test, and cardiac magnetic resonance. Patients were divided into 2 groups (arrhythmic and no-arrhythmic MVP), according to the presence of VA with a right bundle branch block pattern. RESULTS: The 62 patients (57%) with arrhythmic MVP showed: 1) higher MAD (median length: 6.0 vs 3.2 mm; P = 0.017); 2) higher prevalence of curling (79% vs 52%; P = 0.012); and 3) higher prevalence of left ventricular LGE (79% vs 52%; P = 0.012). Mediation analysis showed that curling had both a direct (P = 0.03) and indirect effect mediated by LGE (P = 0.04) on VA, whereas the association between MAD and VA was completely mediated by LGE. Patients with severe VA showed more pronounced morphofunctional alterations, in terms of MAD (7.0 vs 4.6 mm; P = 0.004) and presence and severity of curling (respectively, 91% vs 64%; P = 0.010; and 4 vs 3 mm; P = 0.004), compared to those without severe VA. CONCLUSIONS: In patients with MVP the occurrence of VA with right bundle branch block morphology is the expression of more severe morphologic, mechanical, and tissue alterations. Curling has both a direct and an indirect effect on VA.

Left ventricular fibrosis in arrhythmic mitral valve prolapse: quantification and comparison of semi-automated techniques assessed by cardiac magnetic resonance.

PURPOSE: Left ventricular (LV) fibrosis has a key role in arrhythmogenesis in patients with mitral valve prolapse (MVP). Cardiac magnetic resonance identifies LV fibrosis by using late gadolinium enhancement (LGE) technique. LGE assessment and quantification in patients with MVP lacks of standardization protocols. METHODS: 66 MVP patients with normal systolic function and without significant regurgitation were enrolled. Semi-automated gray-scale thresholding techniques using full width at half maximum (FWHM) and 2, 3 and 5 standard deviation (SD) above the remote myocardium were used and compared with the visual assessment, considered as the gold standard. RESULTS: LGE was identified in 41 MVP patients (62%) and quantified. The mean quantity of LGE visually assessed was 2.40 ± 1.07% or 1.40 ± 0.82 g. With FWHM, LGE resulted 3.56 ± 1.23% or 1.99 ± 1.13 g. Using thresholding, the mean LGE quantity was 9.2 ± 3.1% or 4.82 ± 2.28 g for 2-SD, 5.72 ± 1.75% or 3.06 ± 1.47 g for 3-SD and 2.36 ± 0.99% or 1.29 ± 0.79 g for 5-SD. The 5-SD measurement in percentage demonstrated a good correlation with LGE quantification visually assessed (2.40 ± 1.07 vs. 2.363 ± 0.9909, p = 0.543). When compared with the gold standard, the 5-SD threshold quantification, both in percentage and in grams, revealed the least intra-observer (respectively, ICC: 0.976 and 0.966) and inter-observer variability (respectively ICC: 0.948 and 0.935). CONCLUSION: The 5-SD gray-scale threshold technique in percentage revealed the best correlation with the visual assessment and an optimal reproducibility in MVP patient.

Detection of butterfly fractures of long bones through multi-slice computed tomography and micro-computed tomography.

Motor-vehicle accidents often result in lower limb injuries with biosseous fractures. The present study aimed at comparing multi-slice computed tomography (MS-CT), micro-computed tomography (micro-CT) and external fractography for the analyses of experimentally produced biosseus leg fractures. Briefly, 48 human legs amputated for medical reasons were defleshed and then experimentally fractured using a 3-point dynamic bending model (70,6 J of impact energy at the middle of the anterior surface of the tibia) producing 38 biosseous and 10 mono-osseous fractures with a total of 86 fractured bones. External fractography detected 63 (73,2%) "butterfly" fractures (24 (27,9%) complete and 39 (45,3%) incomplete), 14 (16,3%) "oblique" fractures, 6 (7,0%) "comminuted" fractures and 3 (3,5%) "transverse" fractures. Forty-three (43) of the 48 included legs displayed at least one butterfly fracture located at the tibia or fibula. MS-CT correctly detected and classified 16 complete and 20 incomplete butterfly fractures, failing to properly classify 27 fractures; 19 of these misclassifications led to an interpretative error on the trauma direction (i.e., 16 incomplete butterfly fractures classified as oblique fractures and 3 incomplete butterfly fractures classified as transverse). Micro-CT correctly detected and classified 22 complete and 37 incomplete butterfly fractures, failing to properly classify 4 fractures; two of these misclassifications led to an interpretative error on the trauma direction (i.e., two incomplete butterfly fractures classified as oblique fractures). Although further studies evaluating a wider number of fractures and fracture patterns are required to drive any definitive conclusions, this preliminary experimental investigation showed that MS-CT and micro-CT represent useful tools for reconstructing the morphology of leg fractures and could be crucial for trauma analysis in the forensic context. MS-CT could be used as a screening tool, micro-CT as second level analysis and external/internal fractography as third level, confirmatory analysis.

Comparative Prognostic Value of Coronary Calcium Score and Perivascular Fat Attenuation Index in Coronary Artery Disease.

Coronary artery disease (CAD) is the leading global cause of mortality, accounting for approximately 30% of all deaths. It is primarily characterized by the accumulation of atherosclerotic plaques within the coronary arteries, leading to reduced blood flow to the heart muscle. Early detection of atherosclerotic plaques is crucial to prevent major adverse cardiac events. Notably, recent studies have shown that 15% of myocardial infarctions occur in patients with non-obstructive CAD, underscoring the importance of comprehensive plaque assessment beyond merely identifying obstructive lesions. Cardiac Computed Tomography Angiography (CCTA) has emerged as a cost-effective and efficient technique for excluding obstructive CAD, particularly in patients with a low-to-intermediate clinical likelihood of the disease. Recent advancements in CCTA technology, such as improved resolution and reduced scan times, have mitigated many technical challenges, allowing for precise quantification and characterization of both calcified and non-calcified atherosclerotic plaques. This review focuses on two critical physiological aspects of atherosclerotic plaques: the burden of calcifications, assessed via the coronary artery calcium score (CACs), and perivascular fat attenuation index (pFAI), an emerging marker of vascular inflammation. The CACs, obtained through non-contrast CT scans, quantifies calcified plaque burden and is widely used to stratify cardiovascular risk, particularly in asymptomatic patients. Despite its prognostic value, the CACs does not provide information on non-calcified plaques or inflammatory status. In contrast, the pFAI, derived from CCTA, serves as an indirect marker of coronary inflammation and has shown potential in predicting adverse cardiac events. Combining both CACs and pFAI assessment could offer a comprehensive risk stratification approach, integrating the established calcification burden with novel inflammatory markers to enhance CAD prevention and management strategies.

CMR Predictors of Favorable Outcome in Myocarditis: A Single-Center Experience.

Background: Cardiovascular magnetic resonance (CMR) has emerged as the most accurate, non-invasive method to support the diagnosis of clinically suspected myocarditis and as a risk-stratification tool in patients with cardiomyopathies. We aim to assess the diagnostic and prognostic role of CMR at diagnosis in patients with myocarditis. Methods: We enrolled consecutive single-center patients with 2013 ESC consensus-based endomyocardial biopsy (EMB)-proven or clinically suspected myocarditis undergoing CMR at diagnosis. The pre-specified outcome was defined as NYHA class > I and echocardiographic left ventricular ejection fraction (LVEF) < 50% at follow-up. Results: We included 207 patients (74% male, median age 36 years; 25% EMB-proven). CMR showed the highest sensitivity in myocarditis with infarct-like presentation. Patients with EMB-proven myocarditis were more likely to have diffuse LGE and right ventricular LGE (p < 0.001), which was also more common among patients with arrhythmic presentation (p = 0.001). The outcome was met in 17 patients at any follow-up time point, more commonly in those with larger biventricular volumes (p < 0.001), CMR-based diagnosis of dilated cardiomyopathy (p < 0.001), and ischemic LGE (p = 0.005). Higher biventricular systolic function (p < 0.001) and greater LGE extent (p = 0.033) at diagnosis had a protective effect. Conclusions: In our single-center cohort of rigorously defined myocarditis patients, higher biventricular systolic function and greater LGE extent on CMR at diagnosis identified patients with better functional class and higher left ventricular ejection fraction at follow-up. Conversely, larger biventricular volumes, CMR-based DCM features, and the presence of an ischemic LGE pattern at diagnosis were predictors of worse functional class and LV systolic dysfunction at follow-up. Larger prospective studies are warranted to extend our findings to multi-center cohorts.

Benefit Over Risk Assessment of CT-guided Lung Core Needle Biopsy With the Coaxial Technique.

BACKGROUND/AIM: Lung percutaneous needle biopsy (PNB) under CT guidance can be performed with a single-needle or with a coaxial (CX) technique. This study evaluated the CX technique in a large cohort of patients who underwent to CT-guided lung PNB in our Institute over a period of 7 years. PATIENTS AND METHODS: We retrospectively collected and analyzed data relative to 700 CT-guided lung PNBs performed from August 2012 to August 2019 in 700 patients (M:F=436:264; mean age=69 years, range=6-93 years) with normal coagulation and pulmonary function. PNB was considered diagnostic if at least one of the collected tissue specimens allowed for histological diagnosis. Pulmonary hemorrhage (PH) and pneumothorax (PNX) were evaluated as present or absent. Statistical analysis was made by Chi-square test of Pearson, Fisher's exact test and Wilcoxon test. RESULTS: The CX technique showed a high diagnostic accuracy (93.0%) and allowed the collection of a great number of appropriate tissue specimens with a single pleural puncture (≥3 specimens in 77.4% of cases). PH was the complication more frequent (55.4%), without significant clinical impact. Global PNXs incidence was high (42.9%), but the introducer allowed to aspirate the PNX with a lower percentage of chest tube placement vs. PNXs not aspirated (6.3% and 13.3%, respectively). CONCLUSION: This large retrospective study confirmed the high diagnostic accuracy of lung PNB with the CX technique and allowed identification of significant factors to achieve a greater diagnostic power and decrease complication rates.

Treat-to-target in real-life psoriatic arthritis patients: achieving minimal disease activity with bDMARDs/tsDMARDs and potential barriers.

OBJECTIVE: (1) to describe the frequency of minimal disease activity (MDA) in a real-life psoriatic arthritis (PsA) cohort, (2) to longitudinally explore predictors of MDA; (3) to examine frequency and predictors of low disease activity (LDA) in patients with axial involvement (axPsA). METHODS: consecutive PsA patients in stable biological/targeted-synthetic Disease-Modifying Anti-Rheumatic Drugs (bDMARDs/tDMARDs) who attended our center were enrolled. Disease activity indices, including MDA and ankylosing spondylitis disease activity score-LDA (ASDAS-LDA) for axPsA, were evaluated at baseline and every 6 months, up to 36 months or bDMARDs/tsDMARDs discontinuation. Patients' history, BMI, comorbidities - including osteoarthritis (OA) and fibromyalgia - were collected. Variables were compared between patients who achieved sustained MDA and those who did not. Multivariable generalized estimating equation (GEE) models were built to identify predictors of MDA and ASDAS-LDA over time. Data were expressed as beta coefficient (95%CI). RESULTS: 104 patients were enrolled, 54% males, mean age 55.7 years; 52% had axPsA. Across all evaluations, 52-61% reached MDA, and 17-24% achieved ASDAS-LDA. AxPsA, fibromyalgia, OA and BMI≥35 were less frequently observed in patients with sustained MDA. The GEE model confirmed the following factors were significantly and independently associated with MDA: age (Beta=-0.05), bDMARDs/tsDMARDs duration (Beta=+0.31), axPsA (Beta=-1.07), fibromyalgia (Beta=-3.35), OA (Beta=-1.87), BMI≥35 (Beta=-2.53). Age (Beta=-0.01), fibromyalgia (Beta=-2.03) and OA (Beta=-1.30) were also independently associated with ASDAS-LDA. CONCLUSIONS: MDA is an attainable target in real-life. AxPsA represents a difficult-to-treat subset. Sustained MDA depends on disease features (axPsA) as well as patients' characteristics (e.g. age, bDMARDs/tDMARDs duration, comorbidities).

Cardiac Magnetic Resonance-Detected Acute Myocardial Edema as Predictor of Favourable Prognosis: A Comprehensive Review.

Acute myocardial edema (AME) is increased water content in the myocardium and represents the first and transient pathophysiological response to an acute myocardial injury. In-vivo and non-invasive evaluation is feasible with cardiac magnetic resonance (CMR), which is a powerful imaging technique capable of tissue characterization. In the clinical setting, early demonstration of AME has a recognized diagnostic value for acute coronary syndromes and acute myocarditis, although its prognostic value is not well established. This article provides a comprehensive narrative review on the clinical meaning of AME in heart diseases. In particular, the available evidence of a possible favourable prognostic value in several clinical scenarios is addressed.
