Admission heart rate and in-hospital course of patients with Takotsubo syndrome.

Background: In-hospital course of patients with Takotsubo syndrome (TS) is quite heterogeneous and life-threatening complications are not uncommon in the acute phase. The role of heart rate (HR) as a predictor of prognosis has not been sufficiently investigated in this setting. The study aims to assess the impact of HR at presentation on in-hospital course of patients with TS.

Cardiac magnetic resonance in patients with acute cardiac injury and unobstructed coronary arteries.

Aim: To define the role of cardiac magnetic resonance (CMR) by analyzing a particular group of patients with suspected acute coronary syndrome (ACS) and normal coronary angiogram.

Methods: From January 2009 to December 2015, we examined 220 patients with clinical suspicion of ACS, Troponin elevation [the threshold used to define a positive Troponin T test (TnT) was 0.1 ng/mL] and no significant coronary disease at angiography (the patients were considered to have significant angiographic disease only a 50% stenosis was detected in any of their coronary arteries).

Tortuosity, Recurrent Segments, and Bridging of the Epicardial Coronary Arteries in Patients With the Takotsubo Syndrome.

Myocardial bridging (MB) and a long recurrent wraparound left anterior descending artery (wrap-LAD) are coronary anatomic variants that have been recently suggested to be associated with takotsubo syndrome (TS). Until now, coronary artery tortuosity (CAT) has never been investigated in this setting. Our study sought to evaluate the prevalence of the aforementioned anatomic variants in a large population with TS.

Ultrasound tissue characterization does not differentiate genotype, but indexes ejection fraction deterioration in becker muscular dystrophy.

The aims of the study were, first, to assess whether myocardial ultrasound tissue characterization (UTC) in Becker muscular dystrophy (BMD) can be used to differentiate between patients with deletions and those without deletions; and second, to determine whether UTC is helpful in diagnosing the evolution of left ventricular dysfunction, a precursor of dilated cardiomyopathy. Both cyclic variation of integrated backscatter and calibrated integrated backscatter (cIBS) were assessed in 87 patients with BMD and 70 controls. The average follow-up in BMD patients was 48 ± 12 mo.

Patterns of late gadolinium enhancement in Duchenne muscular dystrophy carriers.

Background: This study was designed to assess whether cardiovascular magnetic resonance imaging (CMR) in Duchenne muscular dystrophy carriers (DMDc) may index any cell milieu elements of LV dysfunction and whether this cardiac phenotype may be related to genotype. The null hypothesis was that myocardial fibrosis, assessed by late gadolinium enhancement (LGE), might be similarly accounted for in DMDc and gender and age-matched controls.

Methods: Thirty DMDc patients had CMR and genotyping with 37 gender and age-matched controls.

[Anomalous origin of the right coronary artery from the left sinus of Valsalva: essential role of computed tomography to clarify the coronary artery course and literature review on diagnostic and therapeutic management in 215 cases].

Coronary artery anomalies are among the most confusing topics in cardiology. Although the medical community is increasingly aware that coronary anomalies can be fatal, the reasons for a sudden fatal event and the frequency with which it occurs are generally unclear. In addition, coronary anomalies are usually compatible with normal prenatal myocardial development and postnatal growth and function, even permitting intense athletic activity.

[Management strategies and choice of antithrombotic treatment in patients admitted with acute coronary syndrome--executive summary for clinical practice. Consensus Document of the Regional Chapters of the Italian National Association of Hospital Cardiologists (ANMCO) and of the Italian Society of Emergency Medicine (SIMEU)].

This document has been developed by the Lazio regional chapters of two scientific associations, the Italian National Association of Hospital Cardiologists (ANMCO) and the Italian Society of Emergency Medicine (SIMEU), whose members are actively involved in the everyday management of Acute Coronary Syndromes (ACS). The document is aimed at providing a specific, practical, evidence-based guideline for the effective management of antithrombotic treatment (antiplatelet and anticoagulant) in the complex and ever changing scenario of ACS. The document employs a synthetic approach which considers two main issues: the actual operative context of treatment delivery and the general management strategy.

Aesthetic subpectoral placement of implantable cardioverter defibrillators.

The implantable cardioverter defibrillator (ICD) is the treatment of choice for life-threatening arrhythmias. Usually, the device is placed, by a subclavian access, on the upper portion of the pectoralis major muscle. As a result, the visibility of the device and the wide subclavian scar create an important aesthetic deformity, especially in young women, evolving in a relevant psychosocial distress.
