We have studied the incidence of possible triggers of the myocardial infarction regarding its site in 750 patients with anterior and 731 patients with inferior infarction. Infarctions occurred most frequently without recalling any triggering activity, especially in patients with anterior infarction (67 vs. 44%). Physical effort as the possible precipitator ...
Banerjee A - - 1996
The diagnosis of early myocardial infarction, especially in association with atypical clinical presentations, can be difficult to establish. Continued observation of high-risk patients, with multiple serial electrocardiographs and the use of other diagnostic modalities as available, is essential to prevent the inadvertent premature discharge of patients with evolving myocardial infarcts ...
Naito J - - 1996
Changes in myocardial integrated backscatter (IB) reflect myocardial viability in patients with myocardial infarction. IB may be obtained separately in the subendocardial and subepicardial layers to establish a transmural trend. The purpose of this study is to examine the possibilities that the measurement of the transmural trend in myocardial IB ...
Wang C H - - 1995
This study was designed to test the hypothesis that thalassemia trait diminishes the likelihood of myocardial infarction. If the hypothesis is true the prevalence of thalassemia trait should be less in myocardial infarct patients than in a control population. Blood counts and blood chemistry data from 500 men in Taiwan ...
Kawano H - - 1995
The NZW x BXSB F1 male mice that a model for systemic lupus erythematosus (SLE) develop myocardial infarction. To determine whether the gene(s) linked to the major histocompatibility complex (MHC) of NZW mice are involved in myocardial infarction, we developed an H-2-congenic NZW.H-2d strain and compared the incidence of myocardial ...
Chin J K - - 1993
Splenic infarction is rare in cirrhotic patients. The diagnosis of the condition is based on clinical findings and splenic imaging. In recent years, ultrasonography and computed tomographic scan have gained popularity over the more classical scintigraphy as the preferred investigations for the diagnosis of splenic infarction. We report three cases ...
Sevilla D C - - 1992
The correlation between myocardial infarct size estimated by the complete version of the Selvester QRS scoring system and that documented by pathoanatomic studies has been reported for single anterior, inferior and posterolateral infarcts. Although previous studies described electrocardiographic changes in patients with multiple infarcts, no quantitative documentation of the ability ...
Haisty W K WK - - 1992
The automated version of the complete Selvester QRS scoring system for estimation of myocardial infarct size was evaluated in 1,344 normal subjects, 706 patients with a single myocardial infarction (366 with inferior infarction, 277 with anterior infarction and 63 with posterolateral infarction) and 131 patients with combined inferior and anterior ...
Nakata T - - 1992
We studied with quantitative techniques the clinical efficacy of indium-111 antimyosin at a later stage of myocardial infarction in 18 patients at various stages after infarction. Antimyosin accumulation was detected irrespective of infarct age and size and quantified as an infarct weight with a tomographic technique. Higher intensities in a ...
Hilgenberg C - - 1992
Descriptive data were gathered from 15 families on which changes in the family were reported as a result of a myocardial infarction in one family member. Persons surviving their first myocardial infarction and their families were interviewed individually and simultaneously by one of five trained interviewers in each subject's home ...

A patient with paramedian thalamic and midbrain infarcts developed palilalia.
Appels A - - 1990
Both cardiologists and psychiatrists have observed that the onset of myocardial infarction is often preceded by feelings of decreasing energy, general malaise, and minor depression. This paper describes these observations and tries to integrate the findings. It is proposed that the mental state preceding myocardial infarction can be best described ...
Perry S - - 1989
Surveys were made to determine whether susceptibility to depressive illness and to myocardial infarction of people living in Wolverhampton was related to the intensity of 50 Hz magnetic field outside their homes. Comparing case with control addresses it was found that the field strength was significantly higher for depressive illness ...
Lachica E - - 1988
A study was performed on 74 medicolegal autopsy cases for the purpose of comparing the reliability of four different techniques (haematoxylin-eosin stain, acridine orange method, formazan test and K/Na ratio) used for the postmortem diagnosis of myocardial infarction. Although the results showed that the formazan test and K/Na ratio give ...
Haywood L J - - 1988
An overview of the problems and management of acute myocardial infarction is presented. Certain factors that are pertinent to the problem of differential mortality in various population subgroups have been identified. These factors include race, sex, and socioeconomic background.
Martin C A - - 1988
Variations in the ratio of "definite" to "possible" myocardial infarction for non-fatal cases were examined in studies that used World Health Organization criteria. There were large variations in this ratio, variations which appeared to be due to differences in the ascertainment of non-fatal cases of "possible" myocardial infarction, which, in ...
Karlsson I - - 1988
A preliminary study of the relationship between a physically active versus a physically non-active life before a myocardial infarction and coping ability (e.g. psychosocial effects) after a myocardial infarction has been performed. In a mainly rural area in south-western Sweden all myocardial infarction sufferers (N = 49) during January 1984-August ...
Cummings R G - - 1988
To quantitate the amount of right and left ventricular infarction in patients dying with postinfarction ventricular septal defect (PIVSD), hearts from 54 patients with anterior or inferior myocardial infarction were studied at autopsy. Fifteen hearts had myocardial infarction with PIVSD and 39 hearts had infarction without PIVSD and were used ...
Beaglehole R - - 1987
New epidemiological criteria for definite myocardial infarction are now in use as part of the international study of trends and determinants of cardiovascular disease coordinated by the World Health Organization (MONICA Project). In this paper we use data from a myocardial infarction register to assess the comparability of the old ...
Herlihy T - - 1987
Nausea and vomiting occurring during myocardial ischemia is believed to be associated with inferior wall infarction. However, data supporting such an association are limited, and an alternative hypothesis that cardiac vomiting is related to infarct size has also been advanced. The 2 hypotheses were tested in a cross-sectional study of ...
Cox P H - - 1987
A crossover study to examine the potential of In111 antimyosin Fab fragment to detect fresh myocardial infarcts in comparison with Tc99m pyrophosphate is reported. In 27 cases indium antimyosin correctly diagnosed 19 patients with infarcts and 4 true negatives. There were also 2 false positive and 2 false negative scintigrams. ...

Health standards for truck drivers are higher than those for the general motoring public, particularly concerning the need to restrict driving following recovery from a myocardial infarction. An analysis of risk shows that at most 12 Ontario truckers would develop a fatal recurrence of infarction in any given year, and ...
Kannel W B - - 1984
Of 708 myocardial infarctions among 5127 participants in the Framingham Study, more than 25 per cent were discovered only through the appearance of new diagnostic evidence during routine biennial electrocardiographic examinations. Of these unrecognized infarctions almost half were "silent," and the others caused atypical symptoms. The proportion of all infarcts ...
Crisp A H - - 1984
Within the general population people destined for myocardial infarction are found to be more obsessional and greater worriers than others. Moreover, in the year before their infarction they display high levels of sadness, anxiety-related symptoms, loss of libido, and fatigue, unrelated to angina and other physical discomforts. They also claim, ...
Adler D D - - 1984
Liver infarcts are relatively rare and uncommonly are diagnosed before autopsy. The CT appearance of hepatic infarction was studied in five patients. In four of these, well-defined, wedge-shaped, low-attenuation zones extending to the liver surface were seen on contrast-enhanced scans. The infarcts involved the right lobe of the liver in ...
Takatsu F - - 1983
To determine the value and limitations of vectorcardiograms (VCGS) for diagnosing multiple myocardial infarctions, correlations between VCG and angiographic findings were analyzed in 307 cases with severe asynergies due to coronary narrowings on left ventriculograms. While the presence of anterioseptal hypokinesis, corresponding to a nontransmural infarction of the anteroseptal wall, ...
Byrne D G - - 1984
State and trait anxiety correlates of eight dimensions of illness behavior in response to myocardial infarction, were examined for 120 survivors of myocardial infarction. Six of eight illness behavior dimensions were found to be significantly associated with measures of state anxiety or trait anxiety or both. Trait anxiety was most ...
De Clerck L - - 1983
A 73 year old man presented with an acute anteroseptal myocardial infarction. He became progressively hypotensive without signs of left heart decompensation or major rhythm disturbances. Swan-Ganz catheterisation revealed a pattern of right ventricular infarction and under appropriate treatment the patient recovered remarkably well. The importance of recognition of right ...
Simpson H C - - 1982
Thirty-two men who had recently had a myocardial infarction were matched individually for age with controls who had no evidence of heart disease. The patients had a significantly lower proportion of linoleic acid and a higher proportion of palmitic acid in their plasma triglyceride fatty acids. Analysis of the composition ...
Tester B - - 1982
We have retrospectively studied changes in blood pressure from CCU admission to the end of convalescence after myocardial infarction in 72 consecutive patients less than or equal to 70 years, who did not receive hypotensive therapy before or during the period of observation. Besides confirming previous observations of an initial ...
Hammond E J - - 1982
The electroencephalogram, and somatosensory and auditory evoked potentials were recorded from a patient, who, at necropsy, showed a restricted unilateral thalmic infarct involving predominantly the anterior and lateral thalamus. The electroencephalogram showed distinct monomorphic delta activity and a suppression of the alpha rhythm over the side of the lesion. Short ...
Nixon J V - - 1982
Perhaps the most important point concerning right ventricular myocardial infarction is to be alert for its occurrence. Approximately one fifth of all infarctions and one third of all inferior infarctions have some right ventricular involvement. All right ventricular infarcts are probably associated with inferior left ventricular infarctions. The correct diagnosis ...
Goldberg R L - - 1982
Myocardial infarction should be understood not only in relation to its biologic impact but also in terms of its psychologic effect. Patients with myocardial infarction pass through identifiable dynamic phases associated with psychologic recovery and adaptation to myocardial damage. These phases consist of denial, anxiety, depression and convalescence. Some therapeutic ...
Lewis S E - - 1981
Myocardial infarct size was estimated by three methods in a canine model, using Tc-99m pyrophosphate at 24 and 48 hr after coronary ligation. A gamma camera provided anterior, LAO, and lateral views, and was then fitted with multipinhole (MPH) and rotating-slanthole (RSH) collimators for tomographic studies, processed by computer to ...
Clements S D SD - - 1981
The electrocardiogram is often the key to the diagnosis of myocardial infarction. In order to use it effectively, the clinician must be aware of its limitations. Most importantly, it must be remembered that a single normal electrocardiogram does not exclude myocardial infarction. In addition, certain clinical entities mimic infarction electrocardiographically ...
Gelfand R - - 1981
A retrospective study of the work status of 45 consecutive male patients who were at least 12 months post myocardial infarction was carried out. The vast majority of patients were in the lower socioeconomic classes. Only 31 percent of those previously working returned to employment. No differences were found in ...
Isiadinso O O - - 1980
Geriatric patients committed to mental institutions often die from infections, neoplasia, drug-related disorders, or cardiopulmonary failure. Myocardial infarction is not usually implicated as the cause of death in these patients. In comparison, infarct-related deaths are quite common in normal patients of comparable age. This observation may, in part, be due ...
Davies G J - - 1979
We have critically evaluated the use of 99m Tc polyphosphate to estimate myocardial infarct size. Optimum conditions were first defined with respect to infarct edge definition, and relative activity over infarct and bone and in blood pool. The scintigrams of 53 patients with acute transmural myocardial infarction were recorded under ...
