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 ...

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. ...

The discriminant accuracy of 14 variables derived from clinical evaluation, cardiac fluoroscopy, exercise electrocardiography, thallium scintigraphy and radionuclide angiography was assessed with respect to the diagnosis of angiographic coronary artery disease (CAD) among 607 patients undergoing coronary angiography, and with respect to the prognosis of subsequent cardiac death or nonfatal ...
Fabián J - - 1988
The study presents data regarding the functional assessment and prognosis of acute myocardial infarction survivors resident in Prague 4 and an industrial region in north Bohemia. No demonstrable differences between the incidence of myocardial infarction in various professions were found. Acute myocardial infarction occurred in 0.52-0.73% of the total number ...
Cohn J N - - 1988
The interaction of physiologic variables that appear to be predictive of prognosis in patients with severe congestive heart failure was examined in a series of 139 patients referred to a heart failure service. Left ventricular ejection fraction, peak oxygen consumption during a progressive maximal exercise test and resting plasma norepinephrine ...
Smith L K - - 1988
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 ...
Sørensen K E - - 1988
To evaluate whether long-term human fetal exposure to beta 2-adrenergic receptor agonists elicit alterations in the human fetal heart, a fetal echocardiographic examination was performed in 9 fetuses between the 24th and 35th week of gestation (median 28 weeks) and 9 age-matched controls. Examinations were performed during long-term tocolytic terbutalin ...

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 ...

More than one in four myocardial infarctions that occurred over 30 years in the Framingham Study were detected only because of routine biennial electrocardiographic examinations. Of these, almost half were completely silent. The fraction of infarctions unrecognized was higher in women (35 per cent) than in men (28 per cent). ...
Nixon J V - - 1986
The rationale for introducing the term "non-Q-wave myocardial infarction" is identified. The incidence, pathology, pathogenesis, and diagnostic criteria for this condition, previously identified as nontransmural or subendocardial infarction, are reviewed. In reviewing the diagnostic criteria, the various noninvasive techniques that may be applied are discussed. The clinical course, prognosis, and ...

In conclusion, systemic sclerosis is both a fascinating and frustrating affliction. It is a systemic disease of multiple stages. Prognosis is dependent on the site and extent of visceral involvement. There is evidence to implicate the vascular system as the primary target organ of the disease. The cardiovascular manifestations include ...
Kotila M - - 1986
A 4-year follow-up study was carried out on the prognosis of 54 patients (36 men and 18 women) who survived their first ischaemic brain infarction which had occurred under the age of 65. Twenty patients (15 men and 5 women) already had documented atherosclerotic vascular disease other than ischaemic brain ...

It has long been thought that the symptomatology and prognosis of coronary events in patients with diabetes may differ from those in nondiabetic persons. A review of recent data demonstrates a higher mortality during the acute phase of myocardial infarction for diabetic patients than for their nondiabetic counterparts, possibly related ...
Elveback L R - - 1985
During the period 1960 through 1979, 1,014 residents of Rochester, Minnesota, had a diagnosis of classic angina pectoris as the first manifestation of coronary heart disease, and 1,013 had a myocardial infarction as the initial manifestation. In the angina cohort, about 50% were men, and of them, 20% were 70 ...

A computer-assisted technique has been developed to assess absolute coronary arterial dimensions from 35 mm cineangiograms. The boundaries of optically magnified and video-digitized coronary segments and the intracardiac catheter are defined by automated edge-detection techniques. Contour positions are corrected for pincushion distortion. The accuracy and precision of the edge detection ...

Although within the capacity of perhaps one to two percent of highly motivated patients after myocardial infarction, long-distance and marathon running do not confer on normal subjects immunity from coronary atherosclerosis or freedom from high grades of ventricular ectopy during running and nonrunning activities. The presence of significant coronary heart ...
Moreno P - - 1984
Non-Q wave myocardial infarctions, also known as nontransmural myocardial infarctions or subendocardial myocardial infarctions, have been managed as "mild" coronary events in the past. Substantial evidence now requires modification of this approach. Because of their tendency to be associated with modest cardiac enzyme level elevations, non-Q wave infarcts often result ...

Coronary heart disease mortality in New Zealand has declined by 20% in the 13 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 1-year survival following a definite ...
Thompson P L - - 1984
Death rates over a nine year period were studied in 1,232 survivors of myocardial infarction. From 1973 to 1981, the 29 to 365 day case fatality rate in 28 day survivors dropped from 13.3% to 3.2%. This down-trend in case fatality was highly significant, averaging 14.3% in each year. After ...
Puletti M - - 1984
In 641 patients (535 men and 106 women) with acute myocardial infarction (AMI), a mortality of 16.63% was recorded among the former and one of 42.45% among the latter. No significant difference was observed in the age groups up to 40 years, in the group from 41 to 55 years, ...
Théroux P - - 1984
Prognosis for the patient recovery from an acute myocardial infarction is related mainly to electrical instability, left ventricular function, residual ischemia, and extent of coronary atherosclerosis. Many procedures now exist that allow investigation of these various aspects of cardiovascular function and stratification of risk. No ideal marker of prognosis exists ...
Uys C J - - 1984
Since the introduction of cardiac transplantation at our institution 15 years ago, major advances have occurred in the monitoring and treatment of these patients, resulting in many long-term survivors. We defined the pathologic features in 14 cardiac transplants with survival times longer than one year. Only one heart showed no ...
Fukui S - - 1984
In order to evaluate the effect of coronary care on the immediate mortality rate of acute myocardial infarction and to clarify the problems in coronary care, we attempted to investigate the immediate mortality rate and causes of deaths in 492 patients with acute myocardial infarction who had admitted to the ...
Horwitz R I - - 1984
Of the two most frequently used indices for classifying prognosis of patients with an acute myocardial infarction, the Killip index, because of its greater simplicity, is sometimes used instead of the more complicated and time consuming Norris index. The purpose of the current research was to correlate the classification of ...
Durairaj S K - - 1984
Long-term prognosis was studied in 72 patients with an ejection fraction (EF) of less than 50 percent after medically treated myocardial infarction. The patients ranged in age from 22 to 67 years. Eighteen deaths (25 percent mortality) occurred during the mean follow-up period of three years. The mortality for patients ...
Taylor S H - - 1984
Therapeutic research into secondary prevention after myocardial infarction has a disappointing cost-benefit record. Many unrecognised biological problems have complicated apparently simple clinical trials. Inadequacies in design have also contributed to the low rate of success in demonstrating a statistically convincing and clinically worthwhile prophylactic benefit of any of the drugs ...
Walker A M - - 1983
The incidence of nonfatal myocardial infarction among 4,733 vasectomized men followed for 33,969 man-years was 1.3 cases per 1,000 man-years. This incidence was nearly identical in a 5-fold larger series of comparable nonvasectomized men. These data represent a substantially increased long-term followup over that reported previously for these groups and ...
