Cardiac ischemia or myocardial infarction after pit viper envenomation is rare. Few case reports have been published, none describing cases reported after crotaline snake envenomation in the United States. We report a case of ST-segment elevation myocardial infarction (STEMI) occurring in a 73-year-old man after an envenomation by a juvenile canebrake rattlesnake (Crotalus horridus). The man was bitten on the left index finger and subsequently developed localized edema followed by hypotension, chest pain, and altered mental status...

Glycemic variability (GV) is relevant to impaired myocardial salvage in acute ST-elevation myocardial infarction (STEMI). Severity of hypokinesis at the infarct site as assessed from contrast left ventriculography can reportedly predict infarct size in STEMI. We prospectively studied 58 consecutive patients (mean age, 63 ± 11 years) with anterior or inferior STEMI who underwent successful reperfusion therapy. Mean amplitude of glucose excursion (MAGE) was obtained from continuous glucose monitoring system...

BACKGROUND: Patients with atrial myocardial infarction (ATMI) have frequent cardiac and noncardiac complications. However, ATMI is uncommonly diagnosed because of its nonspecific electrocardiographic changes. HYPOTHESIS: Our objective was to analyze the electrocardiographic characteristic of ATMI in patients with inferior STEMI. METHODS: A total of 932 patients who underwent coronary angiography were evaluated. Thirty-nine patients with ATMI and 33 patients without ATMI with inferior STEMI were recruited for a retrospective study...

Assessing the efficacy of revascularization therapy in patients with ST-segment elevation myocardial infarction (STEMI) is extremely important in order to guide subsequent management and assess prognosis. We aimed to determine the relationship between corrected QT-interval (QTc) changes on standard sequential ECG and myocardial salvage index in anterior STEMI patients after successful primary percutaneous coronary intervention. Fifty anterior STEMI patients treated by primary percutaneous coronary intervention underwent quantitative ECG analysis and cardiac magnetic resonance...

An ECG pattern of widespread ST depression in six or more precordial and inferior leads, accompanied by ST-segment elevation in the aVR and/or V1 leads, is typical of the non-ST-segment elevation myocardial infarction (NSTEMI) pattern associated left main (LM) artery occlusion, but this ECG pattern is really associated with a subocclusion of the LM, or in the case that the LM was occluded with the presence of collateral circulation. There are few reports of ST-elevation myocardial infarction (STEMI) due to acute total LM occlusion...

The purpose of this case repots are to evaluate the role of ST elevation in aVR lead and to make analysis between both cases. There are some atypical electrocardiogram (ECG) presentations which need prompt management in patient with ischemic clinical manifestation such as ST elevation in aVR lead. In this case study, we report a 68-year old woman with chief symptoms of shortness of breath and chest discomfort. She was diagnosed with cardiogenic shock, with Killip class IV, and TIMI score of 8. The second case is a 57-year-old man with typical chest pain at rest which could not be relieved with nitrate treatment...

Coronary artery ectasia (CAE) is an uncommon anomaly, usually found in 1.2-2% of patients undergoing coronary angiography, defined as a segment of the coronary artery that has a diameter of more than 1.5 times the normal adjacent segments. Atherosclerosis is considered as the cause of half of the CAE cases. We herein present a 65-year-old Asian male with past medical history of Kawasaki disease (KD) who developed recurrent episodes of inferior wall ST-elevation myocardial infarction (STEMI) despite treatment with dual antiplatelet therapy (DAPT)...

OBJECTIVES: This study sought to examine the relationship between temperature at reperfusion and infarct size. BACKGROUND: Hypothermia consistently reduces infarct size when administered prior to reperfusion in animal studies, however, clinical results have been inconsistent. METHODS: We performed a patient-level pooled analysis from six randomized control trials of endovascular cooling during primary percutaneous coronary intervention (PCI) for ST-segment elevation myocardial infarction (STEMI) in 629 patients in which infarct size was assessed within 1 month after randomization by either single-photon emission computed tomography (SPECT) or cardiac magnetic resonance imaging (cMR)...

BACKGROUND: Terminal "QRS distortion" on the electrocardiogram (ECG) (based on Sclarovsky-Birnbaum's Grades of Ischemia Score) is a sign of severe ischemia, associated with adverse cardiovascular outcome in ST-segment elevation myocardial infarction (STEMI). In addition, ECG indices of the acuteness of ischemia (based on Anderson-Wilkins Acuteness Score) indicate myocardial salvage potential. We assessed whether severe ischemia with or without acute ischemia is predictive of infarct size (IS), myocardial salvage index (MSI) and left ventricular ejection fraction (LVEF) in anterior versus inferior infarct locations...

OBJECTIVE: ECG ST segment resolution (STR) has been used to assess myocardial perfusion in STEMI patients undergoing PPCI. However, in most of the studies ECGs recorded at different time points after the actual procedure have been used, limiting the options of therapeutic interventions while the patient is still in the catheterisation laboratory. The aim of this study was to investigate the presence and clinical consequences of intra-procedural STR during PPCI. METHODS: We analysed 12 lead ECGs recorded at the onset and the end of the PPCI procedure, measuring STR in the lead with maximum ST elevation on the initial recording...

Coronary artery ectasia (CAE), a variant of coronary artery anomalies, is a rare clinical entity. Although atherosclerotic coronary artery disease (CAD) is the most common cause of acute coronary syndrome (ACS), CAE also conveys a relatively high risk for potentially life-threatening cardiac events. We report a case of a 35-year-old male with two-vessel CAE, who presented with acute inferior wall ST election myocardial infarction (STEMI). After initiating medical therapy including bivalirudin, emergent percutaneous coronary intervention (PCI) with stenting of postero-lateral branch of right coronary artery (RCA) was performed...

A 42-year-old woman presented to the emergency department with chest pain. Acute coronary syndrome was ruled out. During dobutamine stress echocardiography (DSE), she developed chest pain and inferior ST elevation. Emergent coronary angiography revealed no culprit lesions but did show an anomalous right coronary artery (RCA). Coronary CT angiography (CCTA) confirmed an anomalous RCA arising from the left coronary cusp with a slit-like ostium and interarterial course (ARCA-LCC-IA). Herein, we review the extant literature on ARCA-LCC-IA, its clinical presentation, the vital role of CTA and MRI in its diagnosis, as well as challenges and controversies surrounding management...

BACKGROUND: Correlation of ST-segment elevation on the 12-lead electrocardiogram (ECG) with the expected affected coronary territory is established in patients with ST-elevation myocardial infarction (STEMI). In patients with non-ST-elevation myocardial infarction (NSTEMI), correlation of ischemic ECG abnormalities with the affected coronary territory has not been well-established. We sought to investigate the correlation of electrocardiographic abnormalities with the location of 1-vessel obstructive coronary artery disease (CAD) in patients with both STEMI and NSTEMI...
