Q-wave versus non-Q wave myocardial infarction: a meaningless distinction.
The whole subject can thus be summed up in two statements. 1. Every appropriately designed study comparing first Q and NQMI's has found no difference in post-MI course of the two categories and no foundation for the common notion that the NQMI is a uniquely "unstable" entity, to be classed with unstable angina in terms of prognosis and management. Nine such studies have been published. On the o...
متن کاملPerpetuation of the myth of the Q-wave versus the non-Q-wave myocardial infarction.
We would like to thank Karamanoukian, Donias and Bergsland for their remarks regarding our randomized trial of percutaneous coronary intervention (PCI) versus coronary artery bypass graft (CABG) in patients with medically refractory myocardial ischemia and risk factors for early mortality with CABG. They raise two specific issues about our surgeons’ CABG methods: 1) variability in myocardial pr...
متن کاملNon-Q wave myocardial infarction management strategies.
In this issue, Heggunje and colleagues dissect out from the VANQWISH Trial patients with non-Q wave myocardial infarction who had a prior myocardial infarction and compare outcomes to those who did not have a prior myocardial infarction. They evaluated the trial primary end-point of death or myocardial infarction at 1 and 12 months as well as the initial randomized treatment strategy. The botto...
متن کاملIdentification of first acute Q wave and non-Q wave myocardial infarction by multivariate analysis of body surface potential maps.
BACKGROUND Patients with acute non-Q wave myocardial infarction (NQMI) appear to have more jeopardized residual myocardium at high risk for subsequent angina, reinfarction, or malignant arrhythmias than patients with acute Q wave myocardial infarction (QMI). Unfortunately, conventional electrocardiographic (ECG) criteria have limited utility in recognizing NQMI. METHODS AND RESULTS The presen...
متن کاملPost-myocardial infarction exercise testing. Non-Q wave versus Q wave correlation with coronary angiography and long-term prognosis.
BACKGROUND The presence or absence of baseline diagnostic Q waves has been believed to compromise the accuracy of standard exercise electrocardiography in identifying severe coronary artery disease (three-vessel and/or left main disease); therefore, a retrospective analysis was performed using a personal computer data base of exercise test responses and cardiac catheterization results to evalua...
