miocardial infarction

Patients with left ventricular ejection fraction below 45% (mean 39+/-3.7%) were randomized either to captopril (n=33) or eprosartan after miocardial infarction (n=33) on days 3-7 of myocardial infarction. All patients were subjected to echocardiography and 40 to perfusion myocardial scintigraphy with (99m)TC-Technetril. Myocardial viability was defined as presence of perfusion reserve in dysfunctional segments during test with nitroglycerin. Dysfunctional myocardium was found to be viable in 62.5% of patients...

A large multicenter cohort study, the DAI study, is being performed on patients with type 2 diabetes mellitus who are followed by diabetic care units in Italy, to study the prevalence and incidence of macrovascular complications. The reference population consists of all patients visited at the participating units in the period September 1998-June 1999. Patients were randomly chosen so as to create a sample representative of the diabetic population visited at the units. Overall, 201 Italian diabetic care units participated in the study and 19,570 patients were included in the study...

A 72-year-old man, smoker, with insuline-dependent diabetes and dislipemia underwent left pneumonectomy. Several episodes of intraoperative hemodynamic instability associated with electrocardiographic ST segment alterations were attributed to surgical manipulation; ischemia was not suspected. Cardiorespiratory failure, related to extensive anterior infarction, developed a few minutes after admission to the postoperative intensive care unit (PICU). Cardiopulmonary resuscitation and mechanical ventilation were required...

A decrease in sexual activity after an acute myocardial infarction (AMI) for both women and men has been reported with one study suggesting that this reduction in sexual activity may precede rather than proceed the AMI. The present study compared the sexual activity of women and men before AMI to the sexual activity of a normative community sample of women and men, to examine whether the above reduction in sexual activity is especially characteristic of women and men who later incur an AMI. This study also investigated the association between selected medical and sociodemographic variables and sexual inactivity of women and men before an AMI...

An important task of the nephrologists during the last century, it has been the search of elements and means that allow us, with the adequate precision, to correlate the functional deterioration of the kidney, and the patient's clinical reality. And the continuous searching of factors and markers that injure them, the prognosis, and early diagnosis, to be able to predict the degree of the organs and patient's survival. Almost parallel survival presage in the natural history of the illness, almost one century ago...

OBJECTIVE: To assess by Doppler echocardiography the structural and functional alterations of rat heart with surgical induced extensive myocardial infarction. METHODS: Five weeks after surgical ligature of the left coronary artery, 38 Wistar-EPM rats of both sexes, 10 of them with extensive infarction, undergone anatomical and functional evaluation by Doppler echocardiography and then euthanized for anatomopathological analysis. RESULTS: Echocardiography was 100% sensible and specific to anatomopathological confirmed extensive miocardial infarction...

We describe the case of a 35-year-old male, who presented with sudden death, secondary to anterior miocardial infarction due to embolism. Echocardiography, transthoracic and transesophageal, revealed a tumor in the anterior mitral leaflet. Tumor, histopathologically an papillary fibroelastoma, was excised and the mitral valve was replaced with a mechanical prosthetic valve. We revised the current literature on intracardiac papillary fibroelastoma.

BACKGROUND: The aim of this study was to evaluate the efficacy of an structured intervention based on a medical advice versus to the ordinary anti-tobacco advice in patients with miocardial infarction who are attended in an Intensive Care Unit (ICU). PATIENTS AND METHODS: 90 patients were randomly selected to receive either the specific intervention (intervention group) or the ordinary advice (control group). The medical advice was given during the ICU hospitalization and during the second, the third and the fourth week...

From october '76 to march '79 at the Clinica Chirurgica I of the University of Bologna 50 renal graft have been performed with living donor in 8 cases and with cadaver donor in 42. In the living donor group there was one death for rejection and sepsis. The remaining 7 patients are all alive with normal renal function. Among the 42 patients with cadaver donor 6 died: 3 early (one for gastric hemorrage, one for necrosis of the ascending colon, and one for rejection) and 3 late (two following many rejection episodes and one for miocardial infarction)...

Obstructive lesions of the left common coronary trunk need surgery if our operability criteria: possibility of at least making a by-pass on the left descending anterior coronary branch and a not seriously compromised miocardial contractility exist. Of the 25 patients operated, there was a mortality of 8% and 3 intra-and post-operatory infarcts; two other patients died after some time (one for extracardiac causes). Other infarcts were not observed. 48% of the patients had incomplete riva-scolarization which after some time had an effect on the objective state of the patients but not on their survival...

The radioisotope 195Aum because of its short halflife of 30 seconds and reduced radiation exposure allows routine first pass examinations in two oblique projections, i.e. right anterior and left anterior oblique. The value of the additional left anterior oblique projection has been examined in 30 patients after previous myocardial infarction by functional imaging in two oblique projections. The multicrystal gamma camera connected with a microprocessor and a contrast injector have been used. For assessment of left ventricular function the following functional images have been adopted: the regional ejection fractions (rEF), the regional ejection rates (rEJR) and the regional mean transit times (rMTT)...

Exercise electrocardiograms were done on one thousand patients referred to the laboratory of exercise tests for: suggestive symptoms of acute heart failure, old miocardial infarction abnormal resting ECG, or evaluation of coronary reserve. The average value of cardiac rate reached for the group, was close to 80%. The maximum exercise loads managed by the men were superior to those of the women, and in general those managed in the negative test were superior in relation to the positive tests. Of the one thousand cases, 20...

The investigation performed has demonstrated that under a great deal of coronary, pulmonary and other organs' disorders, in the venous and lymphatic beds of the heart compensatory-adaptive and pathological changes occur. The earliest and deepest changes are noted in the microcirculatory bed. Most of morphological signs on vascular reconstruction are not specific and are observed at different kinds of clinical and experimental pathology. Changes in venous and lymphatic vessels of pathological conditions& do not only result from damage in the organ's wall or hemodynamical changes in the cavities of the cardiac vessels but they themselves can cause some disturbances in the miocardial microcirculation intensifying its hypoxia, congestive symptoms and enhancing the development of decompensation in the organ...
