the important role of reperfusion therapies in the treatment of acute myocardial infarction is well documented. however, reperfusion therapies can initiate inflammatory response and may damage the myocardium. the purpose of current study was to compare the effects of percutaneous coronary intervention and thrombolytic therapy on inflammatory markers in the setting of st elevation myocardial inf...

ST-segment elevation during exercise testing has been attributed to myocardial ischemia and wall motion abnormalities (WMA). However, the functional significance of ST-segment elevation during dobutamine stress testing (DST) has not been evaluated in patients referred for diagnostic evaluation of myocardial ischemia. DST (up to 40 micrograms/kg/min) with simultaneous echocardiography and techne...

To ascertain whether exercise testing might predict multivessel coronary disease and left ventricular aneurysm after a myocardial infarction, 154 patients with a single documented myocardial infarction who had both exercise testing and coronary angiography were grouped according to whether they had greater than or equal to 1 mm ST depression, greater than or equal to 1 mm ST elevation, or neith...

BACKGROUND Glucose-induced insulin secretion is one of the contributing factors to fluctuation of ST segment elevation in Brugada syndrome. OBJECTIVES The purpose of this study was to explore the influence of meals on variations of ST elevation in Brugada syndrome. METHODS We assessed changes of ST segment elevation in lead V1-3 on ECG before and after taking meals, at midnight, and at 3:00...

Background—In the United States, efforts are underway to improve timely access to percutaneous coronary intervention in ST-elevation myocardial infarction (STEMI). The Joint Commission (TJC) and the American College of Cardiology National Cardiovascular Data Registry (NCDR) have developed standardized definitions and clinical performance measures for STEMI. The purpose of this study was to dete...

Asymptomatic ST segment elevation in a life insurance applicant's ECG raises several prognostically important possibilities such as myocardial infarction, pericarditis, Brugada syndrome and early repolarization. This ECG case study discusses the ECG features involved in the differential diagnosis.

Seventy four patients (66 men, eight women; mean age 54.3 years) underwent submaximal exercise testing 7-23 days (mean 10.7) after acute myocardial infarction. Follow up was a mean period of 11.3 months. When compared with patients with no exercise induced abnormality, ST segment elevation, ST shift (depression or elevation or both), ST depression, inability to complete five metabolic equivalen...

Secondary cardiac cancer most frequently originates from primary lung cancer and most commonly occurs in the pericardium. On electrocardiographic examination, patients with secondary cardiac cancer occasionally show ST segment elevation that mimics acute coronary syndrome, despite the absence of coronary artery occlusion. We herein describe a rare case of secondary cardiac cancer that presented...
