Precordial ST-Segment Mapping

Precordial ST-segment mapping was applied serially in the coronary care unit for the study of 46 patients with myocardial infarction (MI), using a 49-lead system. Data from the maps were compared with clinical status of patients, conventional ECGs obtained simultaneously, and serum enzyme levels. Stability of the maps over a one hour period was noted in the early phase of admission. However, a ...

Evaluation of praecordial ST segment mapping as an index of infarct size in patients with acute myocardial infarction.

We evaluated the usefulness and limitations of praecordial ST segment mapping as a clinical means of assessing the size of acute myocardial infarction in 14 patients with anterior myocardial infarction and 13 patients with inferior myocardial infarction. sigma ST, the sum of ST segment elevations, and nST, the number of leads showing ST segment elevation, were obtained from serial electrocardio...

Post-conditioning reduces infarct size and edema in patients with ST-segment elevation myocardial infarction.

OBJECTIVES This study aimed to determine whether post-conditioning at the time of percutaneous coronary intervention could reduce reperfusion-induced myocardial edema in patients with acute ST-segment elevation myocardial infarction (STEMI). BACKGROUND Myocardial edema is a reperfusion injury with potentially severe consequences. Post-conditioning is a cardioprotective therapy that reduces in...

Correlation between leukocyte count and infarct size in ST segment elevation myocardial infarction

INTRODUCTION Regarding the inflammatory mechanisms involved in ischemic heart disease, currently the leukocyte count is the subject of studies related to its association with the prognosis and mortality of ST segment elevation myocardial infarction (STEMI). Our aim is correlate the leukocyte count rise with the size of STEMI, evaluated with the area under the curve (AUC) and the peak of necrosi...
