Exercise electrocardiography with or without thallium-201 scintigraphy was performed (pre-hospital discharge) in 66 asymptomatic survivors of a first inferior myocardial infarction (IMI). Although coronary angiography revealed an 82% incidence of multivessel coronary artery disease (MV-CAD) in the total cohort, the sensitivity of exercise ECG for MV-CAD in the group with absent anterior ST-depr...

OBJECTIVE To assess the five year prognostic significance of transient myocardial ischaemia on ambulatory monitoring after a first acute myocardial infarction, and to compare the diagnostic and long term prognostic value of ambulatory ST segment monitoring, maximal exercise testing, and echocardiography in patients with documented ischaemic heart disease. DESIGN Prospective study. SETTING C...

The presence of ST segment depression in right-sided electrocardiographic leads has been infrequently reported in the literature. We report the cases of two patients with anterolateral and posterior myocardial infarctions with ST segment depression in right-sided electrocardiographic leads. We hypothesize that this electrocardiographic change is a reciprocal expression of ST segment elevation o...

OBJECTIVES We evaluated the clinical significance of reciprocal ST-segment depression associated with exercise-induced ST-segment elevation for detecting residual viability within the infarcted area. BACKGROUND Although the relation between residual viability and exercise-induced ST-segment elevation has been described, there are no reports focusing on the relation between myocardial viabilit...

A transducer-tipped catheter with simultaneous frequency modulated electrocardiograms and a miniaturised tape recorder was used to record ambulatory pulmonary artery pressure for 24-48 hours in 19 men (mean age 57.7) with clinical and angiographic evidence of coronary artery disease. Sixty seven episodes of ST segment depression (greater than 1 mm) were recorded. Thirty five were accompanied by...

mHE exercise electrocardiogram is a fairly well established and frequently used procedure as an adjunct in the diagnosis of symptomatic or latent coronary insufficiency. Many authors have confirmed its value.'-" The criteria for a positive test, however, still remain somewhat controversial. The value of "ischemic" type ST-segment depression is well documented, but the problem of the significanc...

A consecutive series of 179 survivors of acute myocardial infarction had a symptom-limited 12-lead electrocardiographic treadmill exercise test, coronary angiographic studies, and left ventriculograms six to eight weeks after infarction. The exercise-induced ST-segment responses were correlated with the presence of multivessel disease, the presence of advanced left ventricular wall motion abnor...

Background. Silent myocardial ischemia is an adverse prognostic marker in patients with coronary disease; however, controlled data on the effect of treatment are sparse and contradictory, and the relations among the occurrence of ST segment depression, drug efficacy, and heart rate are unclear. Methods and Results. Sixty patients with stable coronary artery disease, a positive treadmill exercis...

BACKGROUND Air pollutants have not been associated with ambulatory electrocardiographic evidence of ST-segment depression ≥ 1 mm (probable cardiac ischemia). We previously found that markers of primary (combustion-related) organic aerosols and gases were positively associated with circulating biomarkers of inflammation and ambulatory blood pressure in the present cohort panel study of elderly s...
