Cardiac lesions secondary to blunt chest trauma vary from insignificant arrhythmias to fatal cardiac rupture. Of these, a distinction remains difficult; face to ST-segment elevation on ECG with positive cardiac biomarkers, is it a myocardial contusion or a genuine myocardial infarction (MI) secondary to coronary lesions? We report the case of a patient admitted for multiple trauma. Initial assessment showed an ST segment elevation on ECG, along with multiple fractures and abdominal injuries. We would like to discuss, through this case, the similarities and the differences between myocardial infarction due to coronary lesions and myocardial contusion in a traumatic context, but also emphasize the difficulty of striking the right balance between thrombotic and bleeding risks in this situation, and insist on the importance of a multidisciplinary and collegial reflexion so we can offer these patients the best care there is...

BACKGROUND: Tpeak-Tend interval (Tp-e interval) in electrocardiogram (ECG) has been reported to predict malignant arrhythmia events (MAE) in ST-segment elevation myocardial infarction and ion channelopathy. Tp-e interval and other ECG parameters as predictors for MAE was evaluated in patients with vasospastic angina (VA). METHODS AND RESULTS: Sixty-two patients with VA (Non-MAE group) and 20 patients with VA complicated by MAE (MAE group) were enrolled in our Division of Cardiology between January 2010 and December 2015...

Introduction: Although percutaneous coronary intervention is an accepted "first-line" therapy in acute ST elevation myocardial infarction (STEMI) in general population, few data are available on the short- and long-term outcomes of very old patients (age >90 years). Our aim is to evaluate and compare the short and long-term outcomes after primary percutaneous coronary intervention (PPCI) or medical therapy in nonagenarian patients with STEMI. Methods: We retrospectively identified patients older than 90 years old in our clinic, with acute STEMI who presented within 12 hours after symptoms onset, either underwent PPCI or medically treated...

BACKGROUND: Early risk stratification after primary percutaneous coronary intervention (PPCI) for ST-segment-elevation myocardial infarction is currently challenging. Identification of a low-risk group may improve triage of patients to alternative clinical pathways and support early hospital discharge. Our aim was to assess whether the index of microcirculatory resistance (IMR) at the time of PPCI can identify patients at low risk of early major cardiac complications and to compare its performance against guideline-recommended risk scores...

Background: Cardiomyocyte progenitor cells (CMPCs) are a promising cell source for regenerative cell therapy to improve cardiac function after myocardial infarction. However, it is unknown whether undifferentiated CMPCs have arrhythmogenic risks. We investigate whether undifferentiated, regionally applied, human fetal CMPCs form a pro-arrhythmic substrate in co-culture with neonatal rat ventricular myocytes (NRVMs). Method: Unipolar extracellular electrograms, derived from micro-electrode arrays (8 × 8 electrodes) containing monolayers of NRVMs (control), or co-cultures of NRVMs and locally seeded CMPCs were used to determine conduction velocity and the incidence of tachy-arrhythmias...

BACKGROUND: The relation between STEMI and air pollution (AP) is scant. We aimed to investigate the short term association between AP and the incidence of STEMI, and STEMI-related ventricular arrhythmias (VA) and mortality. METHODS: The study was carried out in the area of Barcelona from January 2010 to December 2011. Daily STEMI rates and incidence of STEMI-related VA and mortality were obtained prospectively. The corresponding daily levels of the main pollutants were recorded as well as the atmospheric variables...

Acute myocardial infarction (AMI) is a common cause of hospitalization and high mortality due to lethal arrhythmias. Sarcoplasmic reticulum Ca(2+) ATPase (sarcoplasmic reticulum Ca(2+) ATPase (SERCA)2) and ryanodine receptor (ryanodine receptor (RyR)2) regulate the cytosolic Ca(2+) ion concentration. Rosmarinic acid (RA) is one of the most common caffeic esters in Rosmarinus officinalis. The present study was conducted to test the hypothesis whether RA can protect cardiac function against AMI and arrhythmias induced by isoproterenol through the regulatory effect of SERCA2 and RyR2 gene expression...

BACKGROUND: There are continuing bed constraints in percutaneous coronary intervention centres (PCI) so efficient patient triage from referral hospitals is pivotal. To evaluate a strategy of PCI centre (PCIC) bed-sparing we examined return of patients to referral hospitals screened by the RETRIEVE (REverse TRIage EVEnts) criteria and validated its use as a tool for screening suitability for same day transfer of non-ST-elevation acute coronary syndrome (NSTEACS) patients post PCI to their referring non-PCI centre (NPCIC)...

A 63-year-old man with an ischaemic cardiomyopathy, supported by the HeartWare left ventricular assist device (LVAD), presented with ventricular tachycardia and inferior ST-elevation myocardial infarction (STEMI) with associated acute right ventricular (RV) dysfunction. He underwent primary percutaneous coronary intervention with balloon angioplasty and placement of three drug-eluting stents in the proximal-to-mid right coronary artery. Post-procedure, ventricular arrhythmias abated, RV systolic dysfunction resolved and RV size normalised...

The prevalence and impact of early ventricular arrhythmias (ventricular tachycardia [VT]/ventricular fibrillation [VF]) occurring before mechanical revascularization for acute ST segment elevation myocardial infarction (STEMI) treated with percutaneous coronary intervention are poorly understood. We sought to investigate the association between early VT/VF and long-term clinical outcomes using data from the Harmonizing Outcomes with Revascularization and Stents in Acute Myocardial Infarction trial. Among 3,602 patients with STEMI, 108 patients (3...

OBJECTIVES: The aim of this study was to investigate whether low-level tragus stimulation (LL-TS) treatment could reduce myocardial ischemia-reperfusion injury in patients with ST-segment elevation myocardial infarction (STEMI). BACKGROUND: The authors' previous studies suggested that LL-TS could reduce the size of myocardial injury induced by ischemia. METHODS: Patients who presented with STEMI within 12 h of symptom onset, treated with primary percutaneous coronary intervention, were randomized to the LL-TS group (n = 47) or the control group (with sham stimulation [n = 48])...

Dyspnea and bradyarrhythmias are frequent adverse effects (AEs) of ticagrelor. AEs commonly occur within the first week of therapy, are dose related and usually mild, but sometimes they may cause drug discontinuation. Currently, the exact mechanisms of ticagrelor-related AEs have not been definitively explained. In addition to the prevalent theory of adenosine overload, other reasonable mechanisms like a direct central stimulation hypothesis was suggested. We present a case of incessant Cheyne-Stokes respiration associated with heart rate instability in patient with congestive heart failure (HF) and non-ST-segment elevation myocardial infarction (NSTEMI), supporting the use of aminophylline as a potential reversal agent of ticagrelor-related AEs...

Postinfarction mechanical dispersion (MD), that is, the regional heterogeneity of myocardial contraction throughout the cardiac cycle, has detrimental effects on left ventricular (LV) function and is related to the occurrence of heart failure and ventricular arrhythmias. However, its prevalence, pathophysiological determinants, and clinical utility are still unknown. The aim of the present study is to clarify these issues. In total, 130 consecutive patients (mean age 60 ± 12 years, 75% male) with a first ST-segment elevation myocardial infarction (STEMI) were included...

The aim of the present study is to assess the clinical impact of atrial fibrillation (AF) in patients with ST-segment elevation myocardial infarction (STEMI) complicated by new-onset AF depending on STEMI location and timing of arrhythmia. We analyzed 4,363 consecutive STEMI patients treated invasively. Finally, 4,099 subjects were included into further analysis, as 264 patients were excluded because of previous AF history. In total, 1,800 (43.9%) subjects with anterior infarction were included into Group 1, whereas Group 2 encompassed 2,299 (56...

Reperfusion of ischemic myocardium is crucial for salvaging myocardial cells from ischemic cell death. However, reperfusion itself induces various deleterious effects on the ischemic myocardium. These effects, known collectively as reperfusion injury, comprise stunned myocardium, reperfusion-induced arrhythmia, microvascular reperfusion injury, and lethal reperfusion injury. No approach has proven successful in preventing any of these injuries in the clinical setting. My colleagues and I recently proposed a new postconditioning protocol, postconditioning with lactate-enriched blood (PCLeB), for the prevention of reperfusion injury...

BACKGROUND: Takotsubo syndrome is an increasingly recognized cause of chest pain and occasionally of cardiogenic shock. Despite rapid improvement of the left ventricular (LV) ejection fraction, recent registry data raise concerns about long-term prognosis. The aim of this study was to test the hypothesis that restoration of normal ejection fraction after acute takotsubo syndrome is not equivalent to full functional recovery. METHODS: Fifty-two patients with takotsubo syndrome (according to the Mayo Clinic criteria plus cardiac magnetic resonance imaging to exclude myocardial infarction) and 44 healthy control subjects of the same age, gender, and cardiovascular comorbidity distribution were prospectively recruited...
