The etiology of a novel cardiac syndrome called "tako-tsubo" cardiomyopathy, otherwise known as "acute onset and reversible left ventricular apical wall motion abnormality (ballooning)," is very similar to that of acute myocardial infarction; however, it may also be associated with emotional or physical stress. We report a case of tako-tsubo-like ...

Simultaneous anterior, inferior, and right ventricular ST-segment elevation myocardial infarction is an unusual condition. A 50-year-old male patient presented with severe, squeezing chest pain of an hour onset. ST-segment elevations were detected in all precordial derivations, DII, DIII, aVF and V3R, V4R. Coronary angiography showed a significant lesion in the ...

BACKGROUND: The role of inflammation in all stages of atherosclerotic disease is increasingly recognized especially in last few years. The chronic inflammatory process can develop to an acute clinical event by the induction of plaque rupture and therefore cause acute coronary syndrome. Creactive protein is a strong predictor of clinical ...

The advances in the early treatment of ST-segment elevation acute myocardial infarction have resulted in a significant reduction in mortality. Early pharmacologic therapy with antiplatelet and antithrombotic therapy coupled with rapid and complete mechanical or pharmacologic reperfusion has been shown to reduce infarct size, improve left ventricular function, and reduce ...

Outcomes are typically graded on the basis of diagnoses coded according to the International Classification of Diseases, Ninth Revision (ICD-9). To facilitate performance measurement, the ICD-9 codes for acute myocardial infarction changed in October 2005 to completely separate non-ST elevation myocardial infarction (NSTEMI; code 410.71) and ST elevation myocardial infarction ...

Stress (takotsubo) cardiomyopathy (SC) is a recently recognized syndrome with clinical and electrocardiographic (ECG) presentation resembling ST elevation anterior myocardial infarction. As experience with this condition has evolved, a more diverse spectrum of 12-lead ECG patterns has emerged that may affect differential diagnosis. Fifty-nine consecutive patients with SC were prospectively ...

Anterior ST-segment elevation is the classic electrocardiographic feature of anterior left ventricular myocardial infarction due to occlusion of the left anterior descending artery. However, anterior ST-segment elevation has also been described in patients with right coronary artery occlusion, in whom concomitant inferior ST-segment elevation is also typically present. A case ...

The purpose of this brief communication is to emphasize that serious errors can occur when the interpreter of electrocardiograms simply identifies, but does not understand, the mechanism responsible for ST-segment elevated myocardial infarction or non-ST-segment elevated myocardial infarction. Such interpretive errors may, in turn, lead to the incorrect treatment of ...

We describe a patient who developed severe ST-segment elevation, pulseless ventricular tachycardia, and cardiac arrest during induction of general anesthesia. This transient ST-segment elevation may have been the result of coronary artery spasm. Awareness of this variant of coronary artery vasospasm--Prinzmetal angina--in patients without clear symptoms or established ischemic heart ...

Antithrombic therapy is recommended to prevent ischemic complications in patients with high-risk non-ST-segment elevation acute coronary syndromes, including patients with unstable angina/non-ST-segment elevation myocardial infarction and patients with ST-segment elevation myocardial infarction undergoing fibrinolysis with fibrin-specific agents. Ischemic benefit from these agents must be balanced against an increased risk of ...
