"Tako-tsubo" cardiomyopathy, also known as "broken heart syndrome," is one of the rarest types of stress-induced cardiomyopathy. It frequently mimics acute coronary syndrome, characterized by transient left ventricular dysfunction, electrocardiographic changes, and release of myocardial enzymes. After treatment, the patients are cured in most cases without sequelae. Tako-tsubo syndrome is rarely considered as a reason for consultation in the forensic department.Herein, we report a case of a 68-year-old woman who was assaulted by her police officer neighbor...

Introduction: Increased galectin-3 is associated with ischemic cardiomyopathy, although its role in early remodeling post-myocardial infarction (MI) has not been fully elucidated. There are no data demonstrating that blocking galectin-3 expression would have an impact on the heart and that its relationship to remodeling is not simply an epiphenomenon. The direct association between galectin-3 and myocardial inflammation, dysfunction, and adverse cardiovascular outcomes post-MI was examined using clinical and translational studies...

Many studies have shown gender differences in the progress of acute coronary syndromes (ACS). These differences include, amongst others, processes involved in hemostasis and inflammation, and in the present study we put forward the hypothesis that these are the primary cause of other differences. The study included 66 ACS patients (27 women and 39 men) aged 43 - 83 years, 23 with non-ST-elevation myocardial infarction (NSTEMI) and 43 with ST-elevation myocardial infarction (STEMI). Blood samples were taken on day 3 (NSTEMI) or day 5 (STEMI) after hospitalization, and fibrinogen, D-dimers, von Willebrand factor, C-reactive protein and interleukin-6 levels measured...

BACKGROUND: Acute myocardial infarction (AMI) is a common high-risk disease with inpatient mortality of 5% nationally. But little is known about this outcome among Asian Americans (Asians), a fast growing racial/ethnic minority in the country. The objectives of the study are to obtain near-national estimates of differences in AMI inpatient mortality between minorities (including Asians) and non-Hispanic Whites and identify comorbidities and sociodemographic characteristics associated with these differences...

BACKGROUND: Cardiac arrest remains a common and lethal condition associated with high morbidity and mortality. Even with improving survival rates, the successfully resuscitated post cardiac arrest patient is also at risk for poor neurological outcomes, functional status and long- term survival if not managed appropriately. Given that acute coronary occlusion has been found to be the leading cause of cardiac arrest, long-term prognosis is good in selected patients after successful out-of-hospital resuscitation and ST elevation myocardial infarction who are taken for immediate coronary angiography, treated with primary percutaneous coronary intervention and hypothermia when indicated...

Coronary ectasia accounts for 0.3%-4.9% of patients undergoing coronary angiography. We conducted the present study to evaluate the angiographic characteristics of ST-elevation myocardial infarction (STEMI) patients with infarct-related coronary artery ectasia (IRAE) undergoing primary percutaneous coronary intervention. We evaluated 667 STEMI patients who were divided into 2 groups of IRAE (n = 81) and non-IRAE (n = 568). Preprocedural thrombolysis in myocardial infarction (TIMI) flow grade, postprocedural TIMI flow grade, thrombus burden grade, and TIMI frame count were then evaluated...

BACKGROUND: In ST-elevation myocardial infarction (STEMI) patients with multivessel (MV) disease, after primary percutaneous coronary intervention (PCI), emerging evidence suggests that significant disease in non-infarct-related coronary arteries (IRAs) should be routinely stented. Whether this procedure should be guided by angiography alone or ischemia testing is unclear. METHODS: All STEMI patients treated with primary PCI between January 1, 2005, and December 31, 2012, at a tertiary cardiology center were reviewed retrospectively...

Our goal was to assess adherence to American College of Cardiology/American Heart Association guideline-based medical therapy in patients admitted with type I non-ST elevation myocardial infarction (NSTEMI) and to determine factors associated with medication administration delay. We performed a retrospective analysis using data from the Acute Coronary Treatment and Intervention Outcomes Network (ACTION) Registry. Baseline patient demographics, 12-lead electrocardiogram (ECG) findings, laboratory values, medications administered and the time they were administered, and in-hospital clinical outcomes were collected...

BACKGROUND: Left ventricular hypertrophy (LVH) has been suggested as a determinant of outcome in patients with ST-segment elevation myocardial infarction (STEMI). However, available data are inconclusive and the underlying mechanisms remain unclear. Therefore, the aim of this study was to evaluate the impact of LVH on myocardial injury and clinical outcome in a large multicenter STEMI population. METHODS: Cardiovascular magnetic resonance was performed in 795 patients within 10 days after STEMI to assess left ventricular (LV) mass and parameters of myocardial injury...

The differential diagnosis of myocardial infarction in patients with a number of potential causes can be challenging, especially when there is no angiographic evidence of coronary obstruction. We describe a case of extensive anterior ST-elevation myocardial infarction in a young male smoker who had a left atrial myxoma and a history of cocaine use 10 hours before the event. Clinical reasoning during a myocardial infarction investigation should be oriented by the probability of the causal relationship between the ischemic event and each factor present in the clinical context...

Introduction: The aim of the study was to determine the utility and safety of three-dimensional contrast low-dose dobutamine echocardiography (3DCLDDE) in the evaluation of myocardial viability early after ST-elevation myocardial infarction (STEMI). Material and methods: We prospectively evaluated a group of 100 consecutive patients. Myocardial viability was assessed using dobutamine echocardiography in 76 patients with segmental wall motion abnormalities, including 37 patients evaluated using 3DCLDDE and 39 patients evaluated using a standard low-dose dobutamine echocardiography protocol (LDDE), alternately...

An 87-year-old woman presented to the emergency department with a 2-week history of progressively worsening shortness of breath, fever and generalised myalgia. She underwent a transcatheter Portico aortic valve implantation for severe symptomatic aortic stenosis 3 months prior to this presentation. Examination revealed a temperature of 40°C and a systolic murmur in the aortic area. Inflammatory markers were elevated, and blood cultures were positive for methicillin-sensitive Staphylococcus aureus A possible diagnosis of infective endocarditis was made as one major and one minor criterion in the modified Duke criteria were fulfilled...

Circulating microRNAs (miRNAs) hold great potential as novel diagnostic markers for acute coronary syndrome (ACS). This study sought to identify plasma miRNAs that are differentially expressed in young ACS patients (mean age of 38.5 ± 4.3 years) and evaluate their diagnostic potentials. Small RNA sequencing (sRNA-seq) was used to profile plasma miRNAs. Discriminatory power of the miRNAs was determined using receiver operating characteristic (ROC) analysis. Thirteen up-regulated and 16 down-regulated miRNAs were identified in young ACS patients...

Objective Acute coronary syndrome (ACS) is associated with several clinical syndromes, one of which is acute non-ST-segment ACS (NSTE-ACS). S100A1 is a calcium-dependent regulator of heart contraction and relaxation. We investigated the association between the serum S100A1 level and the Global Registry of Acute Coronary Events (GRACE) risk score in patients with NSTE-ACS and the potential of using the serum S100A1 level to predict the 30-day prognosis of NSTE-ACS. Methods The clinical characteristics of 162 patients with NSTE-ACS were analyzed to determine the GRACE score...

Takotsubo cardiomyopathy, also known as "broken heart syndrome," is a transient left ventricular dysfunction associated with stress (usually emotional) induced myocardial injury and stunning. It often presents as myocardial infarction on surface electrocardiogram (EKG). Diagnosis is made by coronary angiography, which rules out coronary artery disease and shows pathognomonic apical ballooning. In this article, we present a case of a 72-year-old woman who initially presented with an ST segment elevation myocardial infarction on EKG...

Renal and neurological involvements are frequently seen in thrombotic thrombocytopenic purpura (TTP). Cardiac involvement, however, has been rarely reported. In this article, we present 2 cases of myocardial infarction in patients with TTP. In the first case, a young man presented with non-ST-segment elevation myocardial infarction that resolved promptly with plasmapheresis. The second patient developed ST-segment elevation myocardial infarction early in the course of the disease and died before plasmapheresis could be initiated...
