Impact of admission hyperglycemia on short and long-term prognosis in acute myocardial infarction: MINOCA versus MIOCA
Background The prognostic role of hyperglycemia in patients with myocardial infarction and obstructive coronary arteries (MIOCA) is acknowledged, while data on non-obstructive coronary arteries (MINOCA) are still lacking. Recently, we demonstrated that admission stress-hyperglycemia (aHGL) was associated with a larger infarct size and inflammatory response in MIOCA, while no differences were observed in MINOCA. We aim to investigate the impact of aHGL on short and long-term outcomes in MIOCA and MINOCA patients. Methods Multicenter, population-based, cohort study of the prospective registry, designed to evaluate the prognostic information of patients admitted with acute myocardial infarction to S. Orsola-Malpighi and Maggiore Hospitals of Bologna metropolitan area. Among 2704 patients enrolled from 2016 to 2020, 2431 patients were classified according to the presence of aHGL (defined as admission glucose level ≥ 140 mg/dL) and AMI phenotype (MIOCA/MINOCA): no-aHGL (n = 1321), aHGL (n = 877) in MIOCA and no-aHGL (n = 195), aHGL (n = 38) in MINOCA. Short-term outcomes included in-hospital death and arrhythmias. Long-term outcomes were all-cause and cardiovascular mortality. Results aHGL was associated with a higher in-hospital arrhythmic burden in MINOCA and MIOCA, with increased in-hospital mortality only in MIOCA. After adjusting for age, gender, hypertension, Killip class and AMI phenotypes, aHGL predicted higher in-hospital mortality in non-diabetic (HR = 4.2; 95% CI 1.9–9.5, p = 0.001) and diabetic patients (HR = 3.5, 95% CI 1.5–8.2, p = 0.003). During long-term follow-up, aHGL was associated with 2-fold increased mortality in MIOCA and a 4-fold increase in MINOCA (p = 0.032 and p = 0.016). Kaplan Meier 3-year survival of non-hyperglycemic patients was greater than in aHGL patients for both groups. No differences in survival were found between hyperglycemic MIOCA and MINOCA patients. After adjusting for age, gender, hypertension, smoking, LVEF, STEMI/NSTEMI and AMI phenotypes (MIOCA/MINOCA), aHGL predicted higher long-term mortality. Conclusions aHGL was identified as a strong predictor of adverse short- and long-term outcomes in both MIOCA and MINOCA, regardless of diabetes. aHGL should be considered a high-risk prognostic marker in all AMI patients, independently of the underlying coronary anatomy. Trial registration data were part of the ongoing observational study AMIPE: Acute Myocardial Infarction, Prognostic and Therapeutic Evaluation. ClinicalTrials.gov Identifier: NCT03883711.
Hyperglycemia, inflammatory response and infarct size in obstructive acute myocardial infarction and MINOCA
Background Hyperglycemia has been associated with increased inflammatory indexes and larger infarct sizes in patients with obstructive acute myocardial infarction (obs-AMI). In contrast, no studies have explored these correlations in non-obstructive acute myocardial infarction (MINOCA). We investigated the relationship between hyperglycemia, inflammation and infarct size in a cohort of AMI patients that included MINOCA. Methods Patients with AMI undergoing coronary angiography between 2016 and 2020 were enrolled. The following inflammatory markers were evaluated: C-reactive protein, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and neutrophil-to-platelet ratio (NPR). Myocardial infarct size was measured by peak high sensitivity troponin I (Hs-TnI) levels, left-ventricular-end-diastolic-volume (LVEDV) and left ventricular ejection fraction (LVEF). Results The final study population consisted of 2450 patients with obs-AMI and 239 with MINOCA. Hyperglycemia was more prevalent among obs-AMI cases. In all hyperglycemic patients—obs-AMI and MINOCA—NLR, NPR, and LPR were markedly altered. Hyperglycemic obs-AMI subjects exhibited a higher Hs-TnI (p < 0.001), a larger LVEDV (p = 0.003) and a lower LVEF (p < 0.001) compared to normoglycemic ones. Conversely, MINOCA patients showed a trivial myocardial damage, irrespective of admission glucose levels. Conclusions Our data confirm the association of hyperglycemic obs-AMI with elevated inflammatory markers and larger infarct sizes. MINOCA patients exhibited modest myocardial damage, regardless of admission glucose levels.
Secondary Prevention Medical Therapy and Outcomes in Patients With Myocardial Infarction With Non-Obstructive Coronary Artery Disease
Myocardial infarction with non-obstructive coronary arteries (MINOCA) is a heterogeneous entity with relevant long-term major cardiovascular events. Several trials have demonstrated that dual antiplatelet therapy (DAPT), β-blocker, renin-angiotensin-aldosterone system (RAAS) inhibitor and statin therapy improve the prognosis in patients with obstructive myocardial infarction (ob-MI). However, evidence on the best medical therapy for secondary prevention in MINOCA patients is lacking. To investigate the effects of secondary prevention treatments at discharge on mid-term outcomes in MINOCA. Patients with acute myocardial infarction (MI) undergoing early coronary angiography between 2016 and 2018 were extracted from a clinical database. The diagnosis of MINOCA was made according to 2016 ESC MINOCA Position Paper criteria. Second-level diagnostic work-up including cardiac magnetic resonance was performed to exclude non-ischemic troponin elevation cause. The relationship between treatments and outcomes was evaluated by using Kaplan-Meier survival analysis and Cox regression models. All confirmed MINOCA were followed in our outpatient clinics. The primary end-points were all-cause mortality, re-hospitalization for MI and a composite outcome including all-cause mortality, hospitalization for MI and ischemic stroke (MACE). Out of 1,141 AMI who underwent coronary angiography, 134 were initially diagnosed as MINOCA. Patients with MINOCA were less likely to receive secondary prevention treatments than patients with obstructive coronary artery disease (CAD) MI (respectively, 42.1% vs 81.8% for DAPT; 75.5% vs 89.6% for β-blockers; 64.7% vs 80.3% for RAAS inhibitor and 63.9% vs 83% for statins). Based on the diagnostic work-up completed during the first month after discharge, a final sample of 88 patients had confirmed MINOCA. During an average follow-up of 19.35 ± 10.65 months, all-cause mortality occurred in 11 (12.5%) patients, recurrence of MI in 4 (4.5%), and MACE in 15 (17.0%) patients. Patients treated with RAAS inhibitors and statins had a significantly longer survival. On the contrary, no increase in survival was found in patients treated with β-blockers or DAPT. Cox multivariable analysis, including all secondary prevention drugs, showed that only RAAS inhibitors were associated with reduced all cause-mortality and MACE. This prospective study suggests that RAAS inhibitor therapy provides mid-term beneficial effects on outcomes in MINOCA patients; in contrast, dual antiplatelet, β-blocker and statin therapy had no effects on mortality and MACE. These results should be considered preliminary and warrant confirmation from larger studies.
Genetics and clinical phenotype of Erdheim–Chester disease: A case report of constrictive pericarditis and a systematic review of the literature
BackgroundErdheim–Chester disease (ECD) is a rare form of histiocytosis. An increasing number of genetic mutations have been associated with this syndrome, confirming its possible neoplastic origin. Recently, a connection between the BRAF mutational status and a specific phenotype was described; however, no studies have yet evaluated the correlations between other mutations and the clinical features of the disease.ObjectivesThis study aims to clarify the association between the clinical phenotype and genetic mutations identified in the neoplastic cell lines of ECD.MethodsWe describe a case of ECD characterized by pericardial involvement and a KRAS mutation shared with chronic myelomonocytic leukemia. Hence, through a meta-analysis of individual participant data of all genetically and clinically described cases of ECD in the literature, we aimed to elucidate the association between its clinical phenotype and baseline genetic mutations.ResultsOf the 760 studies screened, our review included 133 articles published from 2012 to April 2021. We identified 311 ECD patients whose genotype and phenotype were described. We found five main genes (BRAF, KRAS, NRAS, PIK3CA, and MAP2K1) whose mutation was reported at least three times. Mutation of BRAF led to a neurological disease (183 of 273 patients, 67%; p < 0.001); KRAS- and NRAS-mutated patients mainly showed cutaneous (five of six patients, 83.3%, p < 0.004) and pleural (four of nine patients, 44%, p = 0.002) involvement, respectively; PIK3CA was not associated with specific organ involvement; and MAP2K1 mutations caused the disease to primarily involve the peritoneum and retroperitoneum (4 of 11, 36.4%, p = 0.01).ConclusionThis work implies a possible influence of baseline mutation over the natural history of ECD, underscoring the importance of a thorough genetic analysis in all cases with the ultimate goal of identifying a possible targeted therapy for each patient.
The role of sleep disorders in the motoric and cognitive trajectories of older physically frail sarcopenic and healthy active subjects: SOMNUS-DARE, a prospective cohort study
Background Sarcopenia, altered bone and systemic metabolism, physical frailty and cognitive decline are age-dependent and interrelated phenomena. Sleep disorders which are erroneously considered as part of the aging process might be the unifying underlying mechanism of accelerated aging. It is well-known that impaired sleep health could predict neurodegeneration and functional decline. However, in current clinical practice, sleep disorders are not routinely screened and only a minority of cases require second-tier specialist techniques. The delay of their assessment, without a comprehensive evaluation, results in higher healthcare costs. The aim of SOMNUS-DARE project is to detect, in a translational manner, the role of sleep disorders in the genesis of physical frailty, sarcopenia, mild cognitive impairment, and to measure their contribution to the progression of these phenomena towards mobility-disability and dementia. Methods SOMNUS-DARE project will evaluate a sample of 300 community-dwelling healthy active and physically frail sarcopenic subjects, aged 65 years or older, free of cognitive impairment and self-sufficient in basic activities of daily living. The effect of sleep disorders on physical, cognitive and cardiovascular function, systemic, bone and muscle metabolism and body composition will be prospectively assessed by performing: comprehensive geriatric assessment; sleep analysis and environmental monitoring; brain MRI, amyloid positron emission tomography; bone densitometry; radiofrequency echographic multi spectrometry; muscle ultrasound; bioimpedance analysis; cardiac ultrasound; dynamic blood pressure monitoring; blood and saliva measurements. Discussion The project will make it possible to analyse an extremely relevant public health problem which is still underestimated in the current clinical practice. The combination of traditional diagnostics and innovative digital health techniques, will allow a translational and multidimensional analysis of sleep disorders and to weigh their impact on physical and cognitive decline and quality-of-life trajectories. The expected results will highlight the importance of sleep as a fundamental determinant of health and will contribute to the activation of clinical diagnostic and therapeutic pathways in older individuals where the tailored approach might contribute to substantial benefit.

Impact of Newly Diagnosed Cancer on Bleeding Events in Patients with Atrial Fibrillation Treated with Direct Oral Anticoagulants
Background In patients with atrial fibrillation (AF), the association between cancer and cardioembolic or bleeding risk during oral anticoagulant therapy still remains unclear. Purpose We aimed to assess the impact of cancer present at baseline (CB) or diagnosed during follow-up (CFU) on bleeding events in patients treated with direct oral anticoagulants (DOACs) for non-valvular AF (NVAF) compared with patients without CB or CFU, respectively. Methods All consecutive patients with NVAF treated with DOACs for stroke prevention were enrolled between January 2017 and March 2019. Primary outcomes were bleeding events or cardiovascular death, non-fatal stroke and non-fatal myocardial infarction, and the composite endpoint between patients with and without CB and between patients with and without CB. Results The study population comprised 1170 patients who were followed for a mean time of 21.6 ± 9.5 months. Overall, 81 patients (6.9%) were affected by CB, while 81 (6.9%) were diagnosed with CFU. Patients with CFU were associated with a higher risk of bleeding events and major bleeding compared with patients without CFU. Such an association was not observed between the CB and no CB populations. In multivariate analysis adjusted for anemia, age, creatinine, CB and CFU, CFU but not CB remained an independent predictor of overall and major bleeding (hazard ratio [HR] 2.67, 95% confidence interval [CI] 1.8–3.89, p  < 0.001; HR 3.02, 95% CI 1.6–3.81, p  = 0.001, respectively). Conclusion During follow-up, newly diagnosed primitive or metastatic cancer in patients with NVAF taking DOACs is a strong predictor of major bleeding regardless of baseline hemorrhagic risk assessment. In contrast, such an association is not observed with malignancy at baseline. Appropriate diagnosis and treatment could therefore reduce the risk of cancer-related bleeding.
Performance of Prognostic Scoring Systems in MINOCA: A Comparison among GRACE, TIMI, HEART, and ACEF Scores
Background: the prognosis of patients with myocardial infarction with non-obstructive coronary arteries (MINOCA) is not benign; thus, prompting the need to validate prognostic scoring systems for this population. Aim: to evaluate and compare the prognostic performance of GRACE, TIMI, HEART, and ACEF scores in MINOCA patients. Methods: A total of 250 MINOCA patients from January 2017 to September 2021 were included. For each patient, the four scores at admission were retrospectively calculated. The primary outcome was a composite of all-cause death and acute myocardial infarction (AMI) at 1-year follow-up. The ability to predict 1-year all-cause death was also tested. Results: Overall, the tested scores presented a sub-optimal performance in predicting the composite major adverse event in MINOCA patients, showing an AUC ranging between 0.7 and 0.8. Among them, the GRACE score appeared to be the best in predicting all-cause death, reaching high specificity with low sensitivity. The best cut-off identified for the GRACE score was 171, higher compared to the cut-off of 140 generally applied to identify high-risk patients with obstructive AMI. When the scores were tested for prediction of 1-year all-cause death, the GRACE and the ACEF score showed very good accuracy (AUC = 0.932 and 0.828, respectively). Conclusion: the prognostic scoring tools, validated in AMI cohorts, could be useful even in MINOCA patients, although their performance appeared sub-optimal, prompting the need for risk assessment tools specific to MINOCA patients.
Sex-Related Disparities in Cardiac Masses: Clinical Features and Outcomes
Background. Cardiac masses (CM) represent a heterogeneous clinical scenario, and sex-related differences of these patients remain to be established. Purpose: To evaluate sex-related disparities in CMs regarding clinical presentation and outcomes. Material and Methods. The study cohort included 321 consecutive patients with CM enrolled in our Centre between 2004 and 2022. A definitive diagnosis was achieved by histological examination or, in the case of cardiac thrombi, with radiological evidence of thrombus resolution after anticoagulant treatment. All-cause mortality at follow-up was evaluated. Multivariable regression analysis assessed the potential prognostic disparities between men and women. Results. Out of 321 patients with CM, 172 (54%) were female. Women were more frequently younger (p = 0.02) than men. Regarding CM histotypes, females were affected by benign masses more frequently (with cardiac myxoma above all), while metastatic tumours were more common in men (p < 0.001). At presentation, peripheral embolism occurred predominantly in women (p = 0.03). Echocardiographic features such as greater dimension, irregular margin, infiltration, sessile mass and immobility were far more common in men. Despite a better overall survival in women, no sex-related differences were observed in the prognosis of benign or malignant masses. In fact, in multivariate analyses, sex was not independently associated with all-cause death. Conversely, age, smoking habit, malignant tumours and peripheral embolism were independent predictors of mortality. Conclusions. In a large cohort of cardiac masses, a significant sex-related difference in histotype prevalence was found: Benign CMs affected female patients more frequently, while malignant tumours affected predominantly men. Despite better overall survival in women, sex did not influence prognosis in benign and malignant masses.
Periprocedural myocardial injury and infarction after myocardial revascularization: incidence, clinical features and prognosis
Myocardial revascularization, either percutaneous or surgical, is the cornerstone of chronic and acute ischemic coronary artery disease therapy. Periprocedural myocardial injury and infarction are possible complications of these procedures. Several pathogenetic mechanisms have been proposed in the setting of percutaneous (distal embolism, vasospasm, obstruction of a minor vessel) or surgical revascularization (prolonged ischemic time, early graft failure, arrhythmia or severe hypotension during the procedure). High-sensitivity cardiac troponins have emerged as the recommended biomarkers due to their important prognostic implications. However, data regarding diagnostic criteria, management and prognostic implications of these complications are lacking. The present review aims to provide an overview regarding the possible diagnostic criteria, management and prognostic role of periprocedural myocardial injury and infarction.
Cardiac masses: classification, clinical features and diagnostic approach
The term cardiac mass refers to benign or malignant cardiac tumors and cardiac metastases but also to pseudotumors, which is a heterogeneous group consisting of thrombi, vegetations and normal variant structures. While primitive cardiac tumors are rare, metastases and pseudotumors are relatively common. The non-invasive diagnostic approach has not been well established in the literature yet. The first-line non-invasive approach consists of echocardiography, which provides good diagnostic accuracy for masses like thrombi, vegetations and some tumors (mainly myxoma and fibroelastoma). In contrast, for other masses, it does not provide information about the potential malignancy because of poor tissue characterization. Second-line (cardiac computed tomography and cardiac magnetic resonance) or third-line (positron emission tomography-computed tomography) evaluations have been validated in the diagnostic approach to cardiac masses by many studies. In fact, a comprehensive diagnostic approach may establish the diagnosis of malignancy without histological report, which is pivotal for the subsequent therapeutic strategy.The aim of this narrative review is to describe the commonly available non-invasive diagnostic techniques for cardiac masses, their potential and limitations and to suggest a diagnostic pathway for common practice.
