OBJECTIVE Research on homelessness among persons with severe mental illness tends to focus on aspects of demand, such as risk factors or structural and economic forces. The authors address the complementary role of supply factors, arguing that "solutions" to residential instability-typically, a series of institutional placements alternating with shelter(More)
We evaluated the effectiveness of early intravenous administration of 750,000 units of streptokinase in 53 patients with acute myocardial ischemia treated by a mobile-care unit at home (9 patients) or in the hospital (44 patients). Treatment was begun an average (+/- S.D.) of 1.7 +/- 0.8 hours from the onset of pain. Non-Q-wave infarctions developed(More)
The angiographic appearance of the coronary arteries was examined in 308 patients with acute myocardial infarction (AMI) who received high-dose intravenous thrombolytic therapy. Coronary angiography was performed on day 7 after admission to the hospital. Patients had an average of 2.4 discrete arterial narrowings or obstructions. The narrowings were(More)
The importance of timing of intravenous streptokinase (SK) administration in patients with acute myocardial infarction (AMI) was evaluated. Intravenous SK, 750,000 U, was administered within 4 hours of the onset of ischemic chest pain to 72 consecutive patients having their first AMI. Six days later, cardiac catheterization was performed to calculate global(More)
Thirty-four patients with acute myocardial infarction were treated prospectively using a new strategy of prehospital intravenous streptokinase given by a physician-operated mobile intensive care unit. The 29 prehospital-treated patients who had experienced no previous myocardial infarction were compared to a similar group treated with streptokinase(More)
The pattern of contraction of the endocardial wall of the left ventricle in the right anterior oblique cineangiogram was studied by using a frame by frame radial technique and a fixed centroid without correction for rotation and translation motion during the cardiac cycle. Spatial defects of contraction were quantitated by measuring the shortening fraction(More)
150 consecutive patients with acute myocardial infarction received 750,000 units of intravenous streptokinase within four hours of pain onset. Angiography was performed on day 6, from which ejection fraction (EF), infarct-related ejection fraction (IREF), and non-infarct related ejection fraction (NREF) were calculated. 50% stenosis was considered to be(More)
Myocardial damage in acute myocardial infarction is a time-dependent process. We examined the influence of very early thrombolytic therapy, comparing prehospital to hospital administration, in a consecutive group of patients with myocardial infarction on mortality, complications and the preservation of left ventricular function. Seven hundred sixty patients(More)
Coronary restenosis after balloon angioplasty is a slow process that develops over a few months. In some patients, with an initially successful angioplasty, an artery that originally had only moderate stenosis becomes totally occluded as a result of restenosis. This report describes 16 such patients out of 415 dilated lesions with late angiographic(More)
Fifty-one successive patients treated with intravenous streptokinase 1.7 +/- 0.8 (mean +/- SD) hours after onset of symptoms of acute myocardial infarction were evaluated during a three-month posthospital follow-up period. Coronary angiography was performed four to nine days after the initial hospital admission. Twenty-eight patients had a second late(More)
