Ambulant myocardial ischemia and its prognostic implications.
R ecently, unrecognized or silent myocardial ischemia has generated considerable interest. While not a new topic, silent ischemia was originally used in the context of asymptomatic or latent coronary artery disease when ischemic-type ST-segment depression was found on exercise electrocardiograms in totally asymptomatic patients. However, in the mid-1970s, when high-quality ambulatory ECG monito...
متن کاملMyocardial Ischemia Therapeutic Implications
Although it is now widely accepted that silent myocardial ischemia detected by ambulatory ECG monitoring (AEM) is the most common form of ischemia, the debate regarding the pathophysiological mechanisms responsible for ischemic episodes during daily life is far from being settled.1,2 Because most of the early investigations in this field had reported that the vast majority of transient ischemic...
متن کاملPrognostic implications of type 2 myocardial infarctions
Purpose: A type 2 myocardial infarction (MI) is due to ischemia from increased oxygen demand or decreased supply. It is not an infrequent complication following non-cardiac surgery or in the setting of acute medical illness. The purpose of this study was to determine whether type 2 MIs had a worse prognosis than a type 1 MI. Methods: The hospital database of a large tertiary-level academic medi...
متن کاملPlasma zinc in acute myocardial infarction. Diagnostic and prognostic implications.
Zinc is a metal component of many important enzymes, and its availability controls the rate of synthesis of nucleic acids and protein. Serum zinc levels have been shown to fall after acute tissue injury, including myocardial infarction. The purpose of this clinical study was to examine the value of plasma zinc measurements in a coronary care unit. Studies were made in 188 patients: 88 with uneq...
متن کاملNon-Q wave myocardial infarction. Pathophysiology and prognostic implications.
Non-Q wave myocardial infarctions, also known as nontransmural myocardial infarctions or subendocardial myocardial infarctions, have been managed as "mild" coronary events in the past. Substantial evidence now requires modification of this approach. Because of their tendency to be associated with modest cardiac enzyme level elevations, non-Q wave infarcts often result in a favorable early or in...
