The impact of UEFA Euro 2020 football championship on Takotsubo Syndrome: Results of a multicenter national registry.

Objectives: The UEFA 2020 European Football Championship held in multiple cities across Europe from June 11 to July 11, 2021, was won by Italy, providing an opportunity to examine the relationship between emotional stress and the incidence of acute cardiovascular events (ACE). Methods and results: Cardiovascular hospitalizations in the Cardiac Care Units of 49 hospital networks in Italy were assessed by emergency physicians during the UEFA Euro 2020 Football Championship. We compared the events that occurred during matches involving Italy with events that occurred during the remaining days of the championship as the control period. ACE was assessed in 1,235 patients. ACE during the UEFA Euro 2020 Football Championship semifinal and final, the most stressful matches ended with penalties and victory of the Italian team, were assessed. A significant increase in the incidence of Takotsubo Syndrome (TTS) by a factor of 11.41 (1.6-495.1, P < 0.003), as compared with the control period, was demonstrated during the semifinal and final, whereas no differences were found in the incidence of ACS [IRR 0.93(0.74-1.18), P = 0.57]. No differences in the incidence of ACS [IRR 0.98 (0.87-1.11; P = 0.80)] or TTS [IRR 1.66(0.80-3.4), P = 0.14] were found in the entire period including all matches of the UEFA Euro 2020 compared to the control period. Conclusions: The data of this national registry demonstrated an association between the semifinal and final of UEFA Euro 2020 and TTS suggesting that it can be triggered by also positive emotions such as the victory in the European Football Championship finals.

Climatic variables in Takotsubo cardiomyopathy: role of temperature.

BACKGROUND: Recent studies documented a seasonal (summer) and circadian (morning) temporal distribution of takotsubo cardiomyopathy (TTC). AIM: The aim of our study was to investigate whether there is a relationship among season, temperature and the occurrence of TTC. A second aim of our study was the comparison of climatic variables in Takotsubo cardiomyopathy versus acute myocardial infarction (AMI). METHODS: We enrolled consecutive patients with TTC in three Italian centres and, for comparison consecutive patients with AMI. The frequency of TTC and AMI patients according to month, season and quartiles of temperature (I quartile: 9.8-15°, II quartile: 15-19°, III quartile: 19-25° and IV quartile: 25-38°C) was reported. Climatic variables of TTC and AMI patients were compared. RESULTS: We included in the study 85 patients with TTC and 900 patients with AMI. It was not observed a significant peak in the occurrence of TTC during summer time; however, when compared with AMI, TTC was more frequent in summer. We found an absolute higher frequency of TTC cases with warmer temperatures. TTC cases occurred during warmer temperatures than AMI. CONCLUSION: Our study does not confirm a summer preference for TTC occurrence, as reported by previous studies, even if, compared with AMI, TTC is more frequent in summer. During warmest days, it was recorded the highest incidence of TTC.

Non-responders to cardiac resynchronization therapy: Insights from multimodality imaging and electrocardiography. A brief review.

BACKGROUND: Cardiac resynchronization therapy (CRT) is a successful strategy for heart failure (HF) patients. The pre-requisite for the response is the evidence of electrical dyssynchrony on the surface electrocardiogram usually as left bundle branch block (LBBB). Non-response to CRT is a significant problem in clinical practice. Patient selection, inadequate delivery and sub-optimal left ventricle lead position may be important causes. OBJECTIVES: In an effort to improve CRT response multimodality imaging (especially echocardiography, computed tomography and cardiac magnetic resonance) could play a decisive role and extensive literature has been published on the matter. However, we are so far from routinary use in clinical practice. Electrocardiography (with respect to left ventricle capture and QRS narrowing) may represent a simple and low cost approach for early prediction of potential non-responder, with immediate practical implications. CONCLUSION: This brief review covers the current recommendations for CRT in HF patients with particular attention to the potential benefits of multimodality imaging and electrocardiography in improving response rate.

Relationship between coronary artery ectasia, cocaine abuse and acute coronary syndromes.

Coronary artery ectasia (CAE) often represents a coronary angiography finding casually detected or following the occurrence of an acute coronary syndrome. The pathogenetic role of cocaine abuse in the genesis of CAE is still little known and very few data are available in literature. We describe a case of a 31-year-old male cocaine user admitted to our department for typical acute chest pain. Coronary angiography showed diffuse coronary ectasia with slow flows and without hemodynamically significant stenosis. An increasing of matrix metalloproteinases values and a reduction of their tissue inhibitors was showed both during hospitalization and at one month after discharge. This case report emphasizes the close relationship between cocaine abuse, CAE and acute coronary syndromes in patients without hemodynamically significant coronary stenosis. As reported by Satran et al, cocaine abuse should be considered an important risk factor for CAE and these patients appear to be at increased risk of angina and acute myocardial infarct. Further studies that can strengthen this hypothesis would be useful to deepen and better analyze this interesting association.

The association between coronary microvascular dysfunction and carotid intima media thickness in patients with cardiac syndrome X.

OBJECTIVE: The aim of this study was to evaluate in patients with cardiac syndrome X (CSX), using validated angiography indices, coronary blood flow and myocardial perfusion of the microcirculation to assess whether there is greater microvascular dysfunction in patients with increase of carotid intima media thickness (C-IMT), compared to those who do not have. METHODS: Our study was performed on a population 124 patients with CSX that underwent coronary angiography and carotid ultrasound. We divided the sample into two categories: patients with increase of C-IMT and those without increase. We calculated Gibson and Yusuf indices for each patient based on angiographic images, including TIMI Frame Count (TFC), Myocardial Blush Grade (MBG) and Total Myocardial Blush Score (TMBS). RESULTS: Our sample compared two groups: patients with increase of C-IMT (n-63) and patients without increase of C-IMT (n-61). We showed that patients with increase C-IMT had a longest TFC of three major coronary arteries (TFC LAD 44.7±12.5; TFC RCA 26.2±6.9; TFC CX 27±5.9), than control group. We found lower MBG on three coronary arteries (MBG LAD 2.5±0.3; MBG RCA 2.3±0.3; MBG CX 2.1±0.32) in patients with increase of C-IMT than control group, with good statistical significance. CONCLUSION: Analysis of microcirculation trough angiography indexes in patients with CSX with increase of C-IMT and without has led to asses that patients with increase of C-IMT population has a greater involvement of microcirculation than patients without.

STEMI patients and nonculprit lesions: To treat or not to treat? and when? A review of most recent literature.

Patients with ST segment elevation myocardial infarction and multivessel disease represent a high percentage of ischemic patient with a worse outcome than patient with single coronary artery disease. Therefore, initial management of these patients is of high importance, but unfortunately this is not clarified yet. We analyze the available literature trying to afford current doubts to determine which way of revascularization is to be preferred. © 2015 Wiley Periodicals, Inc.

Coronary involvement in Churg-Strauss syndrome.

Systemic autoimmune diseases are themselves a relevant and independent risk factor for atherosclerosis and coronary ectasia. We describe a case of a 58-year-old Caucasian man who was admitted to our department for unstable angina. History of asthma, paranasal sinus abnormality, and peripheral eosinophilia given a high suspicion of Churg-Strauss syndrome (CSS). Diagnosis was performed with 5 of the 6 American College of Rheumatology criteria. The knowledge that CSS is often associated with significant coronary artery involvement and the persistence of chest pain led us to performing immediately a coronary angiography. Coronary angiography showed diffuse ectasic lesions, chronic occlusion of left anterior descending artery with homocoronary collateral circulation from left circumflex artery and subocclusive stenosis in the proximal tract of posterior descending artery. The early recognition of CSS, an aggressive invasive diagnostic approach, and an early appropriate therapy are important to prevent the progressive and permanent cardiac damage in these patients. In the setting of a multidisciplinary approach, careful cardiac assessment is an essential step in CSS, even in mildly symptomatic patients.

A Risk Score Derived from the Analysis of a Cluster of 27 Serum Inflammatory Cytokines to Predict Long Term Outcome in Patients with Acute Myocardial Infarction: a Pilot Study.

BACKGROUND: The aim of our study was to evaluate the clinical utility and prognostic significance of a cluster of 27 serum cytokines for risk stratification after myocardial infarction. MATERIALS AND METHODS: We enrolled 33 consecutive patients admitted to our institution for acute myocardial infarction and prospectively followed. We evaluated traditional cardiovascular risk factors and assayed, during the acute phase, 27 serum cytokines (IL-1, IL-1ra, IL-2, IL-4, IL-5, IL-6, IL -7, IL-8, IL-9, IL-10, IL-12, IL-13, IL-15, IL-17, EOTAXIN, FGF, G-CSF, GM-CSF, IFN-γ, IP-10, MCP-1, MIP-1α, MIP-1ß, PDGF, RANTES, TNF-α, VEGF) potentially associated with cardiovascular risk. Patients were divided into two groups during follow-up according to the occurrence or absence of adverse cardiovascular events (recurrence of angina, re-infarction, death, need of new revascularization, occurrence of heart failure). We developed an additive risk score by assigning one point for each cytokine that had a value greater than the median value (range 0-27). Cytokines alone and the cytokines score were related to cardiovascular events. RESULTS: Patients with and without major adverse cardiovascular events (MACEs) at follow up had a homogenous distribution of the main cardiovascular risk factors; differences were detected only for sex and age. Patients who experienced MACE had a significantly different distribution of I troponin (p=0.036), IL-8 (p=0.006), IL-13 (p=0.06), IL-10 (p=0.02), IL-17 (p=0.015), IP-10 (p=0.02), MIP-1ß (p=0.05). At univariate analysis, IL -8 (p=0.046 OR 1.13), IL-10 (p=0.05 OR 1.14) and MIP-1ß (p=0.016, OR 1.02) were significantly associated with the occurrence of MACE. This association was not confirmed at multivariate analysis. At the analysis of variance, a higher score was significantly associated with the occurrence of adverse events at follow up (F=5.07, p=0.03). At ROC curve analysis, a score greater than 13 better predicted the occurrence of adverse events at follow-up (AUC 0.72, p=0.03, sensibility 59.1%, specificity 81.8%). CONCLUSIONS: In our study we did not identify a single inflammatory cytokine able to predict adverse events in a long term follow up, whereas the presence of more than 13 cytokines above the median value was useful for risk stratification.

Angiographic Evaluation of Coronary Microvascular Dysfunction in Patients with Heart Failure and Preserved Ejection Fraction.

BACKGROUND: The aim of this study was to evaluate myocardial perfusion and coronary blood flow through validated angiography indices to assess whether there is greater MVD in patients with microvascular angina and HFPEF compared to those who do not have. METHODS: Our study was performed on a population of 286 patients with stable angina that underwent coronary angiography and echocardiography. They showed epicardial coronary arteries free from stenosis. We divided the sample into two categories: patients with HFPEF and those without. We calculated indices for each patient based on angiographic images, including TFC, MBG, and TMBS. RESULTS: Our sample compared two groups: HFPEF (n = 155) and non-HFPEF (n = 135) patients. We showed that patients with HFPEF had a longest TFC of three major coronary arteries (TFC LAD 44.7 ± 12.5; TFC RCA 26.2 ± 6.9; TFC CX 27 ± 5.9) than non-HFPEF patients (TFC LAD 40.7 ± 11.6; TFC RCA 25 ± 6.3; TFC CX 21 ± 4.7). On the other hand, we found lower MBG on three coronary arteries (MBG LAD 2.1 ± 0.3; MBG RCA 2.1 ± 0.3; MBG CX 2.0 ± 0.32) in HFPEF than non-HFPEF patients (MBG LAD 2.6 ± 0.5; MBG RCA 2.2 ± 0.47; MBG CX 2.3 ± 0.4). CONCLUSION: Analysis of microcirculation through angiography indices in patients with and without HFPEF has led to assess that the HFPEF population has a greater involvement of microcirculation than patients without HFPEF.

Coronary artery fistulas as a cause of angina: How to manage these patients?

Coronary artery fistulas represent the most common hemodynamically significant congenital defect of the coronary arteries and the clinical presentation is mainly dependent on the severity of the left-to-right shunt. We describe a case of a 55-year-old man with history of chest pain and without history of previous significant chest wall trauma or any invasive cardiac procedures. A coronary multislice computed tomography showed two large coronary fistulas arising from the left anterior descending coronary artery and ending in an angiomatous plexus draining into the common pulmonary trunk. Coronary angiography confirmed the CT finding and showed a third fistulous communication arising from the sinus node artery. Although coronary fistulas are infrequent, they are becoming increasingly important because their management and treatment could prevent serious complications. The latest guidelines of the American College of Cardiology/American Heart Association indicate as Class I recommendation the percutaneous or surgical closure for large fistulas regardless of symptoms. In this manuscript, we provide a detailed review of the literature on this topic, focusing on the clinical management of these patients.

[Short-term effects of stimulation in the right ventricular outflow tract]. / Effetti a breve termine della stimolazione in tratto di efflusso del ventricolo destro.

INTRODUCTION: Stimulation in the right ventricular outflow tract (RVOT) showed better clinical and hemodynamic results at short, medium and long term than apical pacing. METHODS: We enrolled 30 patients undergoing pacemaker implantation with positioning of electrocatheters in the high or low RVOT. All patients underwent clinical, echocardiographic and electrocardiographic evaluation after implantation and at 6-month follow-up. RESULTS: After 6 months of pacing, no significant changes in echocardiographic parameters were observed, whereas differences were found between the duration of spontaneous QRS and the duration of QRS stimulated at the time of implantation. Electrocatheter implantation in the high RVOT showed a particular benefit. CONCLUSIONS: Chronic stimulation in RVOT, preferably in the high tract, can be considered a viable alternative to apical pacing in patients with likely high rates of stimulation, especially of young age.

G-protein-coupled receptor kinase 5 polymorphism and Takotsubo cardiomyopathy.

BACKGROUND: Takotsubo cardiomyopathy (TTC) is an increasingly reported clinical syndrome that mimics acute myocardial infarction without obstructive coronary artery disease and is characterized by transient systolic dysfunction of the apical and/or mid-segments of the left ventricle. The syndrome mainly occurs in postmenopausal women with high adrenergic state conditions. Nowadays, the pathophysiology of TTC is not yet known and the possibility of a genetic predisposition is controversial. AIMS: The purpose of this study was to assess the genetic susceptibility to TTC through analysis of the L41Q polymorphism of the G-protein-coupled receptor kinase 5 (GRK5). METHODS AND RESULTS: In a cohort of 20 patients enrolled in two tertiary Italian centers with diagnosis of TTC, accordingly to the commonly accepted Mayo Clinic criteria and in 22 healthy individuals (control) we have evaluated the polymorphism in GRK5 gene. The TTC patients had a mean age of 65 ±â€Š9 years and 19 of 20 were women. The presence of one or two L41 alleles of GRK5 was significantly more frequent in TTC group than in the control group (40 vs. 8%, P = 0.0372). CONCLUSION: In our study, we have found a significant difference in the frequency of GRK5 polymorphism between TTC patients and controls, supporting a genetic predisposition to this cardiac syndrome.
