Takotsubo cardiomyopathy (TCM), first described in Japan in the early 1990s, is a reversible non-ischaemic cardiomyopathy of unclear aetiology characterised by transient left ventricular dysfunction. It mimics acute myocardial infarction with ST segment changes (STEMI), although evidence of occlusive coronary artery disease is absent. TCM is typically triggered by an ...

Despite outstanding antiplatelet properties of aspirin and clopidogrel, some patients taking these drugs continue to suffer complications. Antiplatelet resistance appears to be a new prognostic factor in acute coronary syndrome patients for clinical events associated with stent thrombosis (ST). However, there is no optimal method to identify it and assess ...

Acute coronary syndrome (ACS) encompasses a spectrum of diseases, ranging from ST-elevation myocardial infarction to non-ST-elevation myocardial infarction and unstable angina. A key initiating event in the pathology of ACS is atheromatous plaque disruption, in which the exposure of thrombogenic material triggers simultaneous activation of primary and secondary hemostatic pathways. ...

Single antiplatelet therapy with aspirin is actually recommended for cardiovascular prevention in patients with stable coronary disease, whereas dual antiplatelet therapy (aspirin and clopidogrel) represents the established treatment in patients with acute coronary syndromes or stable angina undergoing percutaneous coronary intervention. However, recurrent ischemic events occur in patients on treatment ...

BACKGROUND: There are few registries documenting clinical practice in Brazilian patients with acute coronary syndrome. OBJECTIVES: Demography description, occurrence of major clinical adverse events and comparative analysis in patients submitted or not to an invasive strategy (coronary angiography and myocardial revascularization) in a Brazilian multicenter registry of acute coronary syndrome. ...

Preexcitation by accessory pathways (APs) is known to cause dyssynchrony of the ventricle, related to ventricular dysfunction. Correction of ventricular dyssynchrony can improve heart failure in cases of dilated cardiomyopathy (DCMP) with preexcitation. Here, we report the first case of a child with DCMP and Wolff-Parkinson-White (WPW) syndrome treated with ...

We describe a 59-year-old patient presenting with ST-elevation acute coronary syndrome. Coronary angiography with intravascular ultrasound (IVUS) showed an important nonsignificant atherosclerotic lesion in the proximal left anterior descending artery (LAD) and presence of bridging in the mid-LAD. Our hypothesis was that focal spasm at this site was the cause ...

Patients with unstable angina pectoris/non-ST-segment elevation myocardial infarction have an acute coronary syndrome. These patients should be treated with dual antiplatelet therapy with the use of aspirin plus either clopidogrel, prasugrel, or ticagrelor, depending on the clinical circumstances. Prasugrel must not be used in patients with a history of stroke ...

Takotsubo syndrome (TTS)/cardiomyopathy is a syndrome that mimics acute myocardial infarction in the absence of coronary artery disease and is characterized by acute onset of chest pain, electrocardiographic abnormalities, and reversible left ventricular dysfunction. It is usually induced by emotional and physical stress. Fluorouracil is one of the most frequently ...

Coronary artery disease is the leading cause of death worldwide and it often clinically manifests as stable angina. The optimal diagnostic and therapeutic strategy of patients with stable angina may be controversial. Coronary revascularization with percutaneous coronary intervention (PCI) is associated with a reduction in cardiovascular events in patients with ...

Brugada syndrome was described in 1992 as a new clinical and electrocardiographic syndrome involving susceptibility to ventricular arrhythmias and sudden cardiac death in patients with no obvious structural heart disease. Brugada syndrome is characterized by a hereditary anomaly in the sodium ion channel (mutation of the SCN5A gene) identified by ...

In recent years, our understanding of the physiologic mechanisms of transient takotsubo cardiomyopathy has improved because of the growing use of emergent heart catheterization in patients who present with severe ischemic syndromes. However, even this procedure has revealed only that, in most patients with takotsubo syndrome, the sudden onset of ...

Guillain-Barré syndrome (GBS) constitutes a heterogeneous group of immune-mediated peripheral neuropathic disorders that can be triggered by a variety of antecedent events. Clinical symptoms are thought to result from streptokinase antibody-mediated damage to the local blood-nerve barrier. We report the case of a 50-year-old man with acute anterior wall myocardial ...

Marfan syndrome is associated with ventricular arrhythmia but risk factors including FBN1 mutation characteristics require elucidation. We performed an observational cohort study of 80 consecutive adults (30 men, 50 women aged 42±15 years) with Marfan syndrome caused by FBN1 mutations. We assessed ventricular arrhythmia on baseline ambulatory electrocardiography as >10 ...

Takotsubo cardiomyopathy (TTC) is a transient left ventricular dysfunction due to akinesia of the left-ventricular (LV) mid-apical segments (apical ballooning), which can cause severe reduction in LV systolic function. The typical clinical picture of TTC include chest pain, electrocardiographic changes consisting of mild ST-segment elevation followed by diffuse deep T-wave ...

An acute coronary ischemic insult may "cause" prolonged post-ischemic myocardial stunning. In spite of being a major stress factor, acute coronary syndrome is regarded as an exclusion criterion for takotsubo syndrome. We describe the case of a 39-year-old female patient presented with anterior ST-elevation myocardial infarction. Emergency coronary angiography revealed ...

Acute coronary syndrome (ACS) encompasses a spectrum of unstable coronary artery disease ranging from transmural myocardial infarction to unstable angina. The immediate management of these patients is dictated by the presence/absence of ST segment changes on electrocardiogram. More and more patients with non-ST elevation ACS are bypassing traditional diagnostic pathways ...

Left ventricular (LV) dysfunction and dilated cardiomyopathy (DCM) are rarely attributable to sustained or incessant tachyarrhythmias in infants and children with Wolff-Parkinson-White (WPW) syndrome. However, several recent reports suggested that significant LV dysfunction may develop in WPW syndrome in the absence of tachyarrhythmias. It is assumed that an asynchronous ventricular ...

Since the introduction of clotting factor concentrates over 50 years ago the life expectancy of patients with hemophilia (PWH) has increased to over 70 years. Consequently, diseases of the ageing population, including coronary artery disease, are increasingly being encountered. These patients present a unique therapeutic problem due to their greatly increased bleeding ...

Acute coronary syndrome is associated with a high incidence of thrombus. The presence of coronary thrombus is often not appreciated on coronary angiography; however, simultaneous use of angioscopy or intravascular ultrasound increases the detection of thrombus. Forceful coronary injection, passage of intracoronary devices, balloon angioplasty and stenting in the presence ...

The development of antiplatelet and antithrombotic therapies, in addition to interventionist strategy, has resulted in great improvements in the outcomes of patients with non-ST-segment elevation acute coronary syndrome. Parallel to therapeutic advances, bleeding, which can be induced during management, increases the risk of recurrent ischemia, myocardial infarction and death. The ...
