RESUMEN
AIM: The aim of this study is to report the heterogeneity of clinical presentation in Tako-Tsubo syndrome (TTS), including a significant prevalence of normal ECG and echocardiographic patterns in a series of consecutive patients from a single center. METHODS AND RESULTS: From our database we selected a total of 168 cases of TTS. A total of 140 of these (Group A); 14 men (10%), mean age 60.3 years, range 39-87; 126 women (90%), mean age 66.1 years, range 43-93; matched the following reported criteria: typical stenocardic pain immediately following an emotional acute stress, or acute medical or surgical event within the preceding 12âh; acute rise and fall of troponin release; absence of significant coronary disease at coronary angiography. ECG findings at presentation ranged from T wave abnormalities (41 cases, 29.3%) to ST elevation (52 cases, 37.1%) and ST depression (11 cases, 7.9%), whereas in 36 cases (25.7%) the ECG was normal. Echocardiography at presentation showed akinesia of the total apical or medium-apical segments in 74 patients (53%), whereas it showed akinesia of left ventricular wall segments in other locations in 30 patients (21%) and even normal regional wall motion and thickening in 36 patients (26%). We described also a series of 13 female patients (mean age 70.2 years; age range 45-85 years) (Group B) who did not complain of chest pain at presentation, but showed a classical Tako-Tsubo evolution of wall motion abnormalities at echocardiography. Finally we selected 15 female patients (mean age 69.3 years; age range 49-89 years) (Group C) who formally did not report acute stress immediately preceding their presentation to the hospital for chest pain. They showed a classical Tako-Tsubo evolution of wall motion abnormalities at echocardiography and only one case of normal ECG pattern at presentation. CONCLUSION: In this series of acute TTS, a wide variability of ECG and echocardiographic patterns are observed, ranging from ST elevation with coexisting segmental wall motion abnormalities of the typical TTS to a clinical presentation characterized by normal ECG and normal segmental wall motion pattern.

Chest pain is a common general practice presentation that requires careful diagnostic assessment because of its diverse and potentially serious causes. However, the evaluation of acute chest pain remains challenging, despite many new insights over the past two decades. The percentage of patients presenting to the emergency departments because of acute chest pain appears to be increasing. Nowadays, there are two essential chest pain-related issues: (i) the missed diagnoses of acute coronary syndromes with a poor short-term prognosis; and (ii) the increasing percentage of hospitalizations of low-risk cases. It is well known that hospitalization of a low-risk chest pain patient can lead to unnecessary tests and procedures, with an increasing trend of complications and burden of costs. Therefore, the significantly reduced financial resources of healthcare systems induce physicians and administrators to improve the efficiency of care protocols for patients with acute chest pain. Despite the efforts of the Scientific Societies in producing statements on this topic, in Italy there is still a significant difference between emergency physicians and cardiologists in managing patients with chest pain. For this reason, the aim of the present consensus document is double: first, to review the evidence-based efficacy and utility of various diagnostic tools, and, second, to delineate the critical pathways (describing key steps) that need to be implemented in order to standardize the management of chest pain patients, making a correct diagnosis and treatment as uniform as possible across the entire country.
RESUMEN
BACKGROUND AND OBJECTIVES: Bicuspid aortic valve (BAV) disease is the most common congenital cardiac malformation. The aim of the present article is to determine clinical and echocardiographic prognostic factors and provide a predictive model of outcome of a large cohort of patients with BAV. METHODS: We retrospectively enrolled 337 patients consecutively assessed for echocardiography at our Cardiology Department from 1993 to 2014. We considered aortic valve replacement, aortic surgery and cardiovascular death as a clinical combined end-point. Predictors of outcome were determined by Cox regression. RESULTS: Mean age was 29.2â±â19.8 years, median 27.1 years. A total of 38.4% patients presented a history of hypertension. Mean duration of follow-up was 8.4â±â6.1âyears, range 0-21 years. A total of 73 patients underwent aortic valve replacement and/or aortic surgery during follow-up. Age at surgery was 45.2â±â15.6 years. Seven patients died because of cardiovascular causes. At multivariate analysis, baseline clinical predictors were history of hypertension [hazard ratio (HR) 2.289, 95% confidence interval (CI) 1.350-3.881, Pâ=â0.002], larger ascending aortic diameter (HR 2.537, 95% CI 1.888-3.410, Pâ<â0.001), moderate-to-severe aortic regurgitation (HR 2.266, 95% CI 1.402-3.661, Pâ=â0.001) and moderate-to-severe aortic stenosis (HR 2.807, 95% CI 1.476-5.338, Pâ=â0.002). A predictive model was created by integrating these four independent covariates. It allows the calculation of calculate a risk score for each patient, which helps better tailor appropriate treatment in BAV patients. CONCLUSION: At enrolment, history of hypertension, a wider aortic diameter, moderate-to-severe aortic regurgitation and aortic stenosis were independently correlated to combined end-point. Long-term follow-up showed low cardiovascular mortality (2.1%) and a high prevalence of cardiac surgery (21.6%).

The Takotsubo cardiomyopathy is a rare haemodynamic dysfunction, only recently reported perioperatively. While the diagnostic criteria have been established and the outcome is known as favorable, the pathophysiological mechanisms are not entirely understood. Here we present the case of a patient scheduled for laparoscopic hysterectomy and adnexectomy, who early postoperatively developed a Takotsubo cardiomyopathy supposedly triggered by an acute hypertensive crisis due to intraoperative fluid overload.
RESUMEN
OBJECTIVES: The left ventricular (LV) response to combined pressure and volume overload [aortic stenosis (AS) and aortic regurgitation (AR)] versus pressure overload (isolated AS)has not been systematically studied. We aimed to assess LV remodeling, functional and hemodynamic consequences inpatients with mixed aortic valve disease versus patients with isolated AS. METHODS: We enrolled 181 patients (67 ± 9 years,109 men) with severe AS (aortic valve area indexed to body surface area <0.6 cm 2 /m 2 ) who underwent preoperative cardiac catheterization and a complete echocardiogram. Pulmonary capillary wedge pressure (PCWP), LV end-diastolic pressure (LVEDP) and pulmonary artery pressure (PAP) were measured. RESULTS: One hundred and ten patients (group A)had isolated severe AS (AR 01) and 71 patients (group B)had mixed aortic valve disease (severe AS plus AR 23). Patients in group B were younger and in a higher New York Heart Association class (p < 0.01). Severity of AS was similar in both groups. Patients in group B had a higher indexed LV mass, a lower LV ejection fraction, and higher PCWP, LVED Pand PAP (all p ≤ 0.01). CONCLUSIONS: Patients with severe AS and significant AR are more symptomatic than patients with isolated severe AS. The increased burden due to the combined lesion induces pronounced LV remodeling and more severe hemodynamic consequences.

Ischemic stroke is one of the leading causes of mortality and the most important determinant of disability in developed countries. Its association with patent foramen ovale is one of the more controversial issues of the literature, also because paradoxical embolism is frequently a diagnosis of suspicion. Up to now, no clinical randomized studies unequivocally demonstrated the causality of this association. Comparing international guidelines there are substantial differences in clinical recommendations among scientific societies, which confirm the uncertainty surrounding this field. Actually, the superiority of transcatheter percutaneous closure over medical therapy alone is not confirmed, partially as a consequence of significant variability in the inclusion criteria, technical approach, peri- and post-procedural therapy among different studies. Moreover, the procedure is very recent and very few studies report prospective data about the safety and effectiveness of patent foramen ovale closure at long-term follow-up. A careful assessment of both clinical characteristics of patients and anatomical features of patent foramen ovale is very helpful to drive a personalized choice for the individual patient. On the basis of the available evidence, this review re-examines the impact of patent foramen ovale in the etiology of cryptogenic cerebrovascular events as well as the advantages and disadvantages of different treatment modalities, waiting for more scientific consensus.

BACKGROUND: Only limited information about clinical characteristics, diagnostic procedures and therapeutic options is available in patients admitted to an intensive cardiac care unit (ICCU) for heart failure. The aim of this study was to evaluate causes of admission, clinical characteristics, diagnostic and therapeutic options, and outcome of patients admitted for heart failure in the ICCU network. METHODS: The BLITZ-3 Registry prospectively included patients admitted by 332 Italian ICCUs. Data of the patients admitted with a principal diagnosis of heart failure are analyzed. RESULTS: From April 7 to 20, 2008, 6986 consecutive patients with acute cardiac conditions were admitted to ICCUs; 966 (14%) out of 6986 patients were admitted for acute heart failure. Heart failure was the second cause of admission after acute coronary syndromes (52%). Mean age of patients admitted for heart failure was 73 years, 42% were female, and diabetes accounted for 32% of heart failure patients. Most patients were admitted to the emergency department (62%), and were discharged by the cardiology ward (65%). Median length of stay in the ICCU was 4 days, and during the stay in ICCU 5% of the patients with heart failure died. Advanced age and elevated creatinine values were associated with a higher risk of death. Echocardiography was performed in 79% of heart failure patients, coronary angiography in 10%, assisted ventilation in 15%, ultrafiltration in 3%, and right catheterization in 1%. Diuretics were administered in 93% of patients admitted for acute heart failure, intravenous nitrates in 41%, inotropes in 22%, beta-blockers in 42%, angiotensin-converting enzyme inhibitors or angiotensin receptor blockers in 66%. CONCLUSIONS: In a nationwide survey, acute heart failure accounted for 14% of hospital admissions in ICCUs. Patients admitted for heart failure are usually old, with frequent comorbidities. Diagnostic and therapeutic procedures are rarely used, with the exception of echocardiography.

BACKGROUND: Guideline-recommended therapies for acute coronary syndromes (ACS) derive from randomized trials in which elderly patients are underrepresented. Although numbers of this population are increasing, they are largely undertreated in the real world. OBJECTIVE: The study evaluates the impact of older age on care for patients with ACS admitted to the Italian Intensive Cardiac Care Units (ICCUs) network. METHODS: We analyzed data from the BLITZ-3 Registry in order to assess in-hospital care among unselected elderly patients (≥75 years). RESULTS: From 7-20 April 2008, 6986 consecutive patients with acute cardiac conditions were admitted to ICCUs and prospectively enrolled; 3636 (52%) had ACS and 38% of them were elderly. Elderly patients had a higher risk profile, their median length of stay in ICCU was longer [4 days, interquartile range (IQR): 3-6 vs. 3 days, IQR: 2-5; Pâ<â0.0001] and guideline-recommended care was applied less often. At multivariable analysis, elderly patients were less likely to receive reperfusion [odds ratio (OR)â=â0.53, 95% confidence interval (CI)â=â0.42-0.67] for ST-elevation, or early coronary angiography (ORâ=â0.45, 95% CIâ=â0.37-0.56) for non-ST elevation ACS. Besides, unadjusted in-ICCU total mortality was higher for elderly patients with ST-elevation (11.8% elderly vs. 1.8% younger patients; Pâ<â0.0001) or non-ST-elevation (3.9% elderly vs. 0.6% younger patients; Pâ<â0.0001) ACS. CONCLUSION: In a nationwide survey, age impacts on care. The elderly with ACS have a higher risk profile but receive less guideline-recommended care than younger patients. Thus, further improvements in care of this population should be pursued.

BACKGROUND: The BLITZ-3 study prospectively evaluated the epidemiology of hospital admissions, the patterns of care and the most important comorbidities in intensive cardiac care unit (ICCU) patients. METHODS: Distribution and level of appropriateness of hospital admissions in relation to type of ICCU were analyzed (type A, 32%, without cardiac cath lab or cardiac surgery; type B, 49%, with cath lab; type C, 19%, with both cath lab and cardiac surgery). The caseload was estimated on the basis of different levels of mortality risk during the ICCU stay: high (>5.1%), intermediate (0.7-5.1%), low (< or = 0.7%). RESULTS: A total of 6986 consecutive patients admitted to 332 ICCUs were enrolled. A median number of 19 patients (interquartile range 15-26) was admitted to each center during the 14 days of enrollment; 28% of the ICCUs admitted more than 25 patients, 48% between 15 and 25, and 24% less than 15. A higher number of type A ICCUs admitted less than 15 patients (p<0.0001), whereas a higher number of type C ICCUs admitted more than 25 patients (p<0.0001). Hospital admissions for ST-elevation myocardial infarction occurred more frequently in type B or C ICCUs (p<0.0001), whereas hospital admission for heart failure mostly occurred in type A ICCUs (p<0.0001). The number of patients not undergoing reperfusion (p<0.0001) or treated with thrombolytic therapy (p<0.0001) was higher in the type A ICCUs. Coronary revascularization with primary percutaneous coronary intervention was performed more frequently in type B and C ICCUs (p<0.0001). Similarly, patients hospitalized for acute coronary syndrome underwent coronary angiography (p<0.0001) and percutaneous coronary intervention more frequently in type B and C ICCUs (p<0.0001). Prevalence of low-risk rather than intermediate- or high-risk patients was higher in type A ICCUs (p<0.05), and prevalence of high- or intermediate-risk patients was higher in type C ICCUs (p<0.05). CONCLUSIONS: The results of the BLITZ-3 study should lead the Italian cardiological community to reflect upon the needed number of ICCUs, the role of Spoke centers for their integration in the interhospital network, and inappropriate hospital admissions for low-risk conditions.

BACKGROUND: Intensive cardiac care units (ICCUs) have shifted from the observation of patients with myocardial infarction to the care of different acute cardiac diseases. However, few data on such an evolution are available. METHODS AND RESULTS: From 7 to 20 April 2008, 6986 consecutive patients admitted to 81% of Italian ICCUs were prospectively enrolled. Patients observed were mainly elderly men (median age 72 years) with several co-morbidities. Most of them were triaged to ICCU from the emergency room, but 15% of admissions were transfer-in from other hospitals. Several diagnostic and therapeutic procedures were applied (78% had echocardiography and 35% coronary angiography) during the ICCU stay [median length 4 days, interquartile range (IQR) 2-5]. The discharge diagnosis was ST-elevation acute coronary syndrome (ACS) in 21%, non-ST-elevation ACS in 31%, acute heart failure (AHF) in 14% and other acute non-ACS, non-AHF cardiac diseases in 34%. Of those with ST-elevation ACS, 60% received reperfusion (15% fibrinolysis and 45% primary percutaneous coronary intervention). The overall in-ICCU crude mortality was 3.3%. CONCLUSION: The BLITZ-3 survey provides a unique snapshot of current epidemiology and patterns of care of patients admitted to ICCUs. Although ACS still remains the most frequent admission diagnosis, the number of non-ACS patients is substantial. However, the correct standard of care for these non-ACS patients has to be defined.

The evaluation of acute chest pain remains challenging, despite many insights and innovations over the past two decades. The percentage of patients presenting at the emergency department with acute chest pain who are subsequently admitted to the hospital appears to be increasing. Patients with acute coronary syndromes who are inadvertently discharged from the emergency department have an adverse short-term prognosis. However, the admission of a patient with chest pain who is at low risk for acute coronary syndrome can lead to unnecessary tests and procedures, with their burden of costs and complications. Therefore, with increasing economic pressures on health care, physicians and administrators are interested in improving the efficiency of care for patients with acute chest pain. Since the emergency department organization (i.e. the availability of an intensive observational area) and integration of care and treatment between emergency physicians and cardiologists greatly differ over the national territory, the purpose of the present position paper is two-fold: first, to review the evidence-based efficacy and utility of various diagnostic tools, and, second, to delineate the basic critical pathways (describing key steps for care and treatment) that need to be implemented in order to standardize and expedite the evaluation of chest pain patients, making their diagnosis and treatment as uniform as possible across the country.

BACKGROUND: Patients with aortic stenosis have a high prevalence of coronary artery disease, but there is little information about the association of coronary artery disease and carotid artery disease. METHODS: The study includes 317 consecutive patients with aortic stenosis, who underwent carotid and coronary angiography during the same catheterization before aortic valve replacement. RESULTS: At univariate analysis, the prevalence of coronary artery disease was associated with (1) presence of carotid artery disease (P < .001); (2) angina pectoris as presentation symptom (P < .001); (3) age more than 65 years (P < .05); and (4) hypertension (P < .05). At multivariate analysis, only carotid artery disease, angina, and age emerged as independent predictors of coronary artery disease. The combination of 2 variables (carotid artery disease, angina) allowed the identification of 4 groups, with decreasing prevalence of coronary artery disease: (1) angina+/carotid artery disease+: 85%; (2) angina-/ carotid artery disease+: 50%; (3) angina+/carotid artery disease-: 41%; (4) angina-/carotid artery disease-: 21% (P < .001). CONCLUSION: In patients with symptomatic aortic stenosis, the presence of significant carotid artery disease is a strong marker of significant coronary artery disease.

BACKGROUND: Brain natriuretic peptide (BNP) is related to symptomatic status and outcome in aortic stenosis (AS) patients. Carbohydrate antigen 125 (CA125) demonstrated recently a BNP-like behaviour in patients with congestive heart failure (CHF) but has never been studied in AS patients. We aimed to assess the role of CA125 and BNP in AS patients. METHODS: CA125 and BNP blood levels, transthoracic echocardiography and independent evaluation of CHF symptoms were obtained in 64 consecutive patients (76+/-9 years; 35 males) with AS (valve area 0.9+/-0.3 cm(2)). A pre-specified combined end-point consisting of cardiac mortality, urgent aortic valve replacement and hospitalization for CHF was considered. The median follow-up was 8 months (interquartile range 4.5-10 months). RESULTS: Both CA125 and BNP have accurately identified patients with III-IV NYHA class: area under the ROC curve was 0.85 for CA125 and 0.78 for BNP (best cut-offs of 10.3 U/mL and 254.64 pg/mL respectively) and were independently correlated to left ventricular ejection fraction. Fifty-two percent of patients with CA125>or=10.3 U/mL vs. 13% with CA125<10.3 U/mL (p<0.01) and 65% patients with BNP>or=254 pg/mL vs. 7% with BNP<254 pg/mL (p<0.001) have reached the end-point. CONCLUSIONS: Both CA125 and BNP levels are significantly correlated with NYHA class and outcome in patients with AS. CA125 blood level assessment (less expensive) may improve the clinical management in this setting.

Drug-eluting stent (DES) implantation has reduced angiographic and clinical restenosis that actually develops in less than 10% of treated patients. DESs also tend to delay the endothelialisation process increasing the risk of stent thrombosis. Subacute stent thrombosis may complicate long-term success of coronary angioplasty; it is a sudden event and usually causes acute myocardial infarction or sudden cardiac death. Patients undergoing DES implantation should be treated with dual antiplatelet therapy for at least 3-6 months. We describe two cases presenting with ST-elevation acute myocardial infarction due to stent thrombosis that occurred late after deployment of a paclitaxel-eluting stent, after discontinuation of antiplatelet therapy. It is important, for clinical cardiologists and general practitioners, to know the potential risk of late thrombosis of DES patients and, consequently, the implications regarding management of antiplatelet therapy.

In acquired human immunodeficiency virus (HIV) infection, a long depolarization period at ECG may be the consequence of cardiac complications due to viral myocarditis or cardiomyopathy or indirectly due to autonomic neuropathy, or sometimes resulting from pharmacological treatments. Several drugs administered for direct treatment of HIV disease or its complications, such as antiretrovirus, fluconazole, and antibiotics, may induce ventricular arrhythmias due to long QT prolonged depolarization period. Also methadone, frequently associated with HIV therapy to treat patients with opiate addiction, is described in the literature to have cardiac inotropic effects. It has also the potential to increase the QT period and to develop ventricular torsade de pointes, primarily through interference with the rapid component of the delayed rectifier potassium ion current. Moreover, the use of methadone associated with other inhibitors of cytochrome P450 might increase plasma concentrations and contribute to methadone cardiac toxicity. We report the case of an HIV patient receiving antiretroviral treatment, fluconazole and high-dose methadone, who suddenly complained of vertigo, dizziness, pre-syncope and syncope due to severe ventricular arrhythmias that disappeared after discontinuation of all treatments.

Disulfiram is a drug used since 1940 in the treatment of alcohol dependence. However, it is not a completely safe drug; there are in the literature some case reports of more severe reaction than the usual "acetaldehyde syndrome" secondary to ingestion of disulfiram and alcohol. We describe a case of a 45-year-old, chronic alcoholic man in treatment with disulfiram, who suffered an acute anterior myocardial infarction, successfully treated with thrombolysis. The possible factors precipitating acute myocardial infarction in this patient are discussed.

Spontaneous closure of a postinfarction ventricular septal rupture is extremely rare. We present such a case in which the postinfarction ventricular septal rupture closed spontaneously during follow-up. We postulate that the spontaneous closure of the ventricular septal rupture was probably due to thrombosis in the apical and septal aneurysm.
