Electrocardiographic changes during chest pain in unstable angina.
Twelve-lead electrocardiograms were recorded during one or more episodes of spontaneous chest pain in 41 patients with unstable angina. Selective coronary angtography and left ventriculography were subsequently carried out in 40 patients. In the remaining patient, the coronary arteries were examined at necropsy. Among the 29 patients with significant coronary artery disease, electrocardiographi...
متن کاملChanges in platelet size and count in unstable angina compared to stable angina or non-cardiac chest pain.
AIMS An increase in platelet aggregability is associated with unstable angina and myocardial infarction. Platelet size and activity correlate and mean platelet volume was found to be increased before acute myocardial infarction. We measured the mean platelet volume and platelet count in patients with stable angina, unstable angina and non-cardiac chest pain. METHODS AND RESULTS We studied 981...
متن کاملAngina pectoris without chest pain.
Response I greatly appreciate the valuable response of Dr Phibbs to my Clinician Update on silent ischemia. Dr Phibbs’ aim was to widen this clinical entity, by stressing that it can be observed also during exercise testing, as he and his colleagues described in 1968,1 and that if its expression is other than angina in the left chest, for example, dyspnea, this should still be included in the d...
متن کامل[Prognostic factors in unstable angina with dynamic electrocardiographic changes. Value of fibrinogen].
INTRODUCTION AND OBJECTIVES The prognosis of unstable angina varies between series depending on the inclusion criteria and management protocol used. The aim of this study was to analyze in-hospital events and their predictors in a homogeneous single-center series of patients with unstable angina. MATERIAL AND METHODS A total of 246 patients with the following inclusion criteria were studied: ...
متن کاملPreinfarctional (unstable) angina--a prospective study--ten year follow-up. Prognostic significance of electrocardiographic changes.
one percent (29 of 140) of the patients developed an acute myocardial infarction within eight months of the onset of the diagnosis of preinfarctional angina with an associated mortality of 41.4% (12 of 29). A combination of high-risk factors in a patient, e.g., frequent angina in the hospital, prior stable angina, and ischemic ST change during pain, identified his as a high-risk case. The high-...
