“…4 In 1976, the prognosis of angina pectoris was investigated by asking GPs to refer patients with new or suspected diagnoses of IHD to a hospital clinic. 5 Although this study drew its sample population from general practice, the follow-up of the patients took place elsewhere, so the outcomes for this group of patients may not be the same as if some of them had remained solely within the general practice setting.…”

“…This figure plots the proportion of one-, two-, and three-vessel and left main coronary artery disease against the duration of anginal symptoms for patients with significant dis- 3 years because of the small number of patients. The survival rate of patients with preinfarction angina is lower than that of patients without preinfarction angina (figures 2 and 3).…”

We investigated the prognostic significance of new-onset angina in patients in whom coronary anatomic characteristics were known. New onset angina was defined as angina of less than 3 months duration. Consecutive patients (n = 1727) with significant coronary artery disease (diagnosed at cardiac catheterization) and who had not had a prior myocardial infarction or congestive heart failure were studied. In patients with new-onset angina (n = 329) there was a higher incidence of single-vessel disease (43% vs 27%) and a lower incidence of triple-vessel (23% vs Circulation 68, No. 5, 970-978, 1983. GIVEN THE MARKED variability in the natural history of coronary heart disease, clinicians have relied on the identification of prognostic factors to help guide therapeutic decisions. The severity of the symptoms, the location of coronary lesions, and left ventricular function are among the factors that are considered in the identification of patients at increased risk of a myocardial infarction or death." 2 Controversy has arisen

“…Patients with other than coronary artery disease are estimated to be 20-60% of all patients who are admitted under the diagnosis of possible unstable angina. 12,13 The ECG documentation of ischemic ST changes is crucial for the diagnosis of these patients.…”

Detection of Myocardial Ischemia With a Computer-Assisted 12-lead 24-hour ECG Monitoring System (EAGLE) in Patients With Suspected Unstable Angina

This study was undertaken to evaluate the diagnostic value of a new device, the 'EAGLE' computer-assisted multiple-lead long-term electrocardiography (ECG) monitoring and analyzing system, in patients with suspected unstable angina, and to compare the results with the Holter monitor. A total of 101 patients with a history of suspected unstable angina underwent a simultaneous 24-h examination with the EAGLE and 2-channel Holter monitors. The diagnosis of unstable angina was established in 70 patients: 41 had significant organic stenosis, and 29 had coronary spasm. Ischemic ST deviations were detected 229 times in 44 patients (62.9%) with the EAGLE system and 101 times in 20 patients (28.6%) with the Holter monitor. The sensitivity of myocardial ischemia in unstable angina with the EAGLE system was significantly higher than that with Holter monitor (62.9 vs 28.6%, p<0.05). The difference of sensitivity was due mainly to the low detection rate of the Holter monitor for asymptomatic myocardial ischemia (EAGLE vs Holter ; 187 times vs 72 times) and myocardial ischemia in the infero-posterior area in patients with organic stenosis (30 times vs none). It is concluded that the EAGLE system is a sensitive tool for the diagnosis of unstable angina in patients without significant ECG changes, and an excellent tool for evaluating silent myocardial ischemia or myocardial ischemia of the infero-posterior area.
