Eighty-eight patients admitted to a coronary care unit with chest pain of varying etiology but without ECG evidence of an acute transmural myocardial infarction had myocardial scintigrams using technetium-99m stannour pyrophosphate (99m-Tc-PYP). Seventeen of these patients had ECG and enzymatic evidence suggestive of acute subendocardial myocardial infarction. In each of ...

Digitalis is one of the oldest and most commonly prescribed medications. There has been continuing controversy regarding its use in acute myocardial infarction. Recent information from animal experiments and clinical investigation serves as a guide for its appropriate use in this situation. When it is used appropriately and judiciously there ...

A retrospective study of the mortality rate of acute myocardial infarction in two groups of patients treated before and after a coronary care unit was established showed no difference between them. Though it is difficult to compare two series retrospectively so far there are no well controlled studies to demonstrate ...

A cooperative study was undertaken to correlate the various methods by which acute myocardial infarction is studied post mortem and to evaluate the histological criteria upon which the diagnosis of acute myocardial infarction should be based. The preliminary results indicate that (1) NBT staining of transverse slices of the heart ...

Of 74 patients seen within 30 minutes of the onset of acute myocardial infarction 68 (92%) had signs of autonomic imbalance. Excessive vagal activity was evident in 41 (55%) and there was sympathetic overactivity in 27 (36%). The high incidence of sudden death in the acute phase of a coronary ...

A 20-year-old male patient is presented as a case of trichinous myocarditis with clinical symptoms and electrocardiographic evidence of an acute inferior myocardial infarction. He recovered rapidly and completely without any specific therapy. This seems to be a distinct rarity, having never been previously reported, but is of importance because ...

The speed of admission of patients with suspected acute myocardial infarction was observed over a period of 12 months during which a "no refusal" coronary care scheme was functioning, with emphasis on minimizing delay. During the same period the duration of survival of cases diagnosed as coronary thrombosis by the ...

A "no refusal" coronary care service (for one year) was offered to a selected sample of 10 general practices (total list 74,657). The patients were admitted to a three-bedded unit in Doncaster Royal Infirmary and data were collected to enable estimation of the size of unit necessary to serve the ...

During 1968, 400 cases of proven acute myocardial infarction were admitted to the Toronto General Hospital (mortality 25.0%).Approximately half the patients who survived their stay in the Emergency Department were admitted to the Coronary Unit (mortality 15.6%) while the other half, because of lack of beds in the Coronary Unit, ...

The effectiveness of intravenous lignocaine in suppressing ventricular ectopic activity after acute myocardial infarction was examined in a double-blind trial in 82 patients. Whereas suppression of unifocal ventricular ectopics was achieved by lignocaine in 90% of patients, other forms of potentially more dangerous ectopic activity (multifocal or R-on-T ectopics) seemed ...

This is a preliminary report of a co-operative study of 1,203 episodes of acute myocardial infarction in men under 70 years in four centres in the south west of England. The mortality at 28 days was 15%. A comparison is made between home care by the family doctor and hospital ...

Fifty-two (6.8%) of 779 patients admitted to a coronary monitoring unit with acute myocardial infarction developed a pericardial friction rub. A diagnosis of postmyocardial infarction syndrome was made in three of these.The course of the 52 patients with pericarditis was compared with that of a consecutive series of 100 patients ...

Acute myocardial infarction is viewed as a severe trauma causing a generalized metabolic reaction; an acute emotional stress with further metabolic implications; and a localized wound in which there is an acute increase in carbohydrate metabolism, followed by protein synthetic reactions leading to scar formation. The metabolic response is vital ...

Four patients with intractable pulmonary oedema after acute myocardial infarction were treated with peritoneal dialysis. A negative fluid balance was rapidly achieved in three patients, two of whom ultimately survived. The fourth patient, who had complete heart block at the beginning of dialysis, showed initial clinical improvement with restoration of ...

A 65-year old woman was admitted with an inferior infarction. Six hours later she developed a pericarditis with specific ECG alterations in the anterior wall accompanied with pericardial and pleural effusion. This early form of true pericarditis after acute myocardial infarction can be explained as an exacerbation of a latent ...

Acute mercurial nephrosis in the rabbit is not associated with a decrease of glomerular circulation.

A brief review is presented on the coronary circulation in acute myocardial infarction. The format of presentation is general anatomy of the human coronary arteries, the blood supply of certain special regions of the heart, and a consideration of how ischaemic malfunction in these regions leads to some of the ...

Glucagon was administered to six patients with acute myocardial infarction. Three of them had cardiogenic shock syndrome. Glucagon produced a positive inotropic response in all cases, which resulted in a significant rise in blood pressure, with only slight chronotropic effect. No arrhythmias were induced, and all patients with cardiogenic shock ...

Thirty-five patients with ventricular dysrhythmias and seven with other dysrhythmias after acute myocardial infarction were treated with intravenous lignocaine.Satisfactory initial suppression of ventricular ectopic beats was achieved in 27 (82%) of 33 patients after either a 50-mg. bolus or a 50-mg. bolus followed by a 100-mg. bolus of intravenous 2% ...

A controlled trial of oral dipyridamole in 103 patients with acute myocardial infarction showed no difference in the number of complications or deaths in either the control or the treated groups. It is concluded that dipyridamole has no benefit in acute myocardial infarction.

All 757 patients with acute myocardial infarction admitted to the three public hospitals in Auckland during one year were studied. About 7% died from cardiac arrhythmia four days or more after the onset of infarction. These patients had severe infarcts with circulatory failure on or shortly after admission to hospital. ...

The LD(50) +/- S.E. of Reduced Iron, N.F. IX, given orally to albino rats was found to be 98.6 +/- 26.7 g. per kg. body weight, or over a hundredfold that of iron given as ferrous sulfate. The clinical and pathological signs of toxicity were somewhat similar to those of ...

The urinary content of glutamic oxalacetic transaminase (UGO-T) was determined in 16 consecutive patients with acute myocardial infarction. In all of them it was above normal. In some patients the UGO-T remained elevated for a longer period than did the blood content of that enzyme.It is possible that in certain ...

By vector methods quantitative differences can be shown to be present between subendocardial and transmural myocardial infarction. In acute transmural infarction the vector shift occurs later, the degree of shift is greater, the return to normal is later in time and an abnormal vector shift remains more frequently than in ...
