Complications of acute myocardial infarction that develop within the first 2 weeks after its onset have been associated with a poor prognosis and dismal surgical outcome. In recent years, aggressive use of hemodynamic monitoring and interventions that improve myocardial oxygen supply and demand have noticeably altered the prognosis. Urgent relief ...
Karlson B W - - 1990
This review of the literature concerns the prognosis of patients suspected of having myocardial infarction subsequent to its exclusion as the diagnosis. Several investigations show a surprisingly bad prognosis for patients in this category, almost comparable to that of patients with a confirmed infarction. When the results of the different ...

Among the 480 patients who underwent heart transplantation in our institution (since 1968), 40 patients received an allograft in the heterotopic position. The recipients were evaluated by using hemodynamics and Doppler echocardiography before and after surgery. Ten to 30 days after surgery, preoperative pulmonary artery pressure, pulmonary artery wedge pressure, ...
Bates E R - - 1989
The prognosis of patients with acute myocardial infarction has improved dramatically over the past several decades. New treatment strategies, however, have incrementally increased the expense of treating these patients. Early hospital discharge is one potential way of offsetting some of this expense. Cardiac catheterization can greatly facilitate patient selection for ...

Two cases of an unusual association between bone infarction and sarcomatous change are reported. The exact incidence of sarcomatous change in bone infarction is unknown. It seems that the risk is greatest in large medullary infarcts of bones. Also, once sarcoma has developed the prognosis is poor. Patients should therefore ...
Del Core M G - - 1989
Although interventional techniques have changed the management of acute phases of myocardial infarction, they have not altered the need for evaluating long-term risk factors. As many as 60% of patients with multiple risk factors die within one year after discharge from the hospital, and these patients often need coronary angiography ...
Cohn J N - - 1989
After acute myocardial infarction, left ventricular filling pressure is elevated because of systolic and/or diastolic dysfunction. The severity of the left ventricular dysfunction is influenced not only by infarct size and location but also by biochemical, neurohormonal, and peripheral vascular responses to infarction. Short-term vasodilator therapy improves left ventricular dysfunction ...
Tatara K - - 1989
The prognosis of coronary artery obstruction was studied in patients with Kawasaki disease. Between May 1973 and December 1987, coronary artery obstruction was diagnosed by coronary angiography in 30 patients (21 males, 9 females), of whom, only 8 (26.7%) had clinical symptoms. One patient died after 9 years of illness. ...
Magnani B - - 1989
To evaluate the impact of infarct size on morbidity and mortality, blood samples were drawn for CPK-MB determination in 144 consecutive patients with first acute myocardial infarction. Enzymatically estimated infarct size was significantly higher in patients who developed in-hospital arrhythmias, congestive heart failure or mechanical complications, or died. After hospital ...

Coronary artery disease can have various clinical manifestations, from the presence of "silent" ischemia to the occurrence of an acute myocardial infarction and congestive myopathy. At each point in the clinical manifestation of coronary artery disease, the practitioner has an evolving number of techniques available to guide decisions regarding prognosis ...
Seth A - - 1988
The recurrence of angina soon after myocardial infarction is not uncommon and represents areas of viable myocardium at risk from infarct extension and thus a worse prognosis. A better understanding of the pathogenesis of acute ischaemic syndromes and developments in interventional cardiology in the past decade have helped us rationalize ...
Shimokawa H - - 1988
To determine the factors influencing the prognosis of variant angina, the clinical characteristics and long-term prognosis of 158 consecutive Japanese patients were examined and compared with those in previous major western studies (Pisa, Montreal, and Duke studies). The Japanese patients were characterized by relatively low prevalences of coronary risk factors, ...
Cohn P F - - 1988
Detection of asymptomatic silent ischemia relies mainly on exercise screening procedures in (1) selected patient subgroups with increased likelihood of having latent coronary artery disease and (2) patients after infarction with uncomplicated courses. Prognosis in these patients varies, depending on the extent of disease and left ventricular dysfunction. The worst ...
Taylor S H - - 1988
The treatment of the patient with acute myocardial infarction remains a complex field of endeavour. Undoubtedly thrombolytic therapy, if instituted sufficiently early, holds considerable promise for the immediate prevention of myocardial necrosis. Alone, however, without further endeavours to remove the offending obstruction that precipitated clot formation in the coronary arteries, ...
Herlitz J - - 1988
In 1,395 patients admitted to hospital between 1976 and 1981 due to suspected acute myocardial infarction, the 5-year mortality rate was related to whether they developed infarction or not during the first 3 days. In all, patients with definite myocardial infarction had a 5-year mortality rate of 33.4% as compared ...

Doxorubicin is a potent anticancer agent effective in a wide range of malignancies, but its use is limited by dose-dependent late cardiotoxicity. Severe doxorubicin cardiotoxicity has been associated with a poor prognosis and a high mortality rate, and until recently has been thought to be irreversible. We describe the cases ...
Appels A - - 1987
In a prospective study of 3877 males, aged 39-65 years, the hypothesis was tested that sleep complaints are predictive of myocardial infarction. It was found that complaints about troubles in falling asleep and about feeling exhausted when one wakes up were predictive of myocardial infarction occurring in a 4.2 years ...
Fukui S - - 1987
In order to investigate the immediate and long-term prognoses of acute myocardial infarction, we followed up 790 consecutive patients who were admitted to the Sakurabashi Watanabe Hospital within 24 hours after the onset of infarction from January 1975 to December 1984 and evaluated early mortality, cumulative survival rate after discharge, ...
Chambers B R - - 1987
We evaluated factors affecting mortality and quality of life in 1,013 patients with acute stroke followed for 2 to 8 years. In cerebral infarction, the major determinants for short-term mortality were impaired consciousness, leg weakness, and increasing age. The major determinants for long-term mortality were low level of activity at ...

Coronary heart disease mortality in New Zealand has declined by 25% in the 15 years since 1968. One possible explanation for this decline is lower case-fatality rates resulting from improvements in the management of myocardial infarction. This paper tests this hypothesis by examining trends in three year survival following a ...
