Telecar: an Italian telecardiology project.

The Telecar (tele-assistance cardiology) project was an example of tele-assistance between health centres of the Regione Lazio in Italy. The project was approved by the Ministry of Health, financed with 500,000,000 lire and carried out by an operative station within 'La Sapienza' University (Rome). About 40 of the health centres in Lazio that did not have cardiologists or electrocardiography (ECG) equipment were provided with telematic instruments (Cardiophone and fax). With this equipment, they were able to transmit ECG signals and receive copies of ECG reports. The 40 health centres included first-aid clinics, 'guardia medica' surgeries and community centres. The project was carried out between 1989 and 1992. During these three years the health centres transmitted a total of 4807 ECGs, 2057 (43%) of which were routine, the remaining 2750 (57%) being suspected emergencies. Of the suspected emergencies, 681 cases (25%) had a confirmed abnormality. We can confirm that telematic aids are very important for an operative station, where all kinds of emergencies must be dealt with.

[The evaluation of in-hospital precoronary times. The experience of a department of emergency medicine].

The above study was aimed at evaluating the "in-hospital precoronary times" of patients with acute myocardial infarction presenting to the Emergency Department of Policlinico Umberto I, Rome. From April to August 1993, 58 cases of acute myocardial infarction were admitted. In six of these, over 24 hrs had elapsed before admission. In 24 of the remaining cases thrombolysis was indicated. Mean time before admission to the coronary unit was 5 hrs for 52 patients. Mean in-hospital delay before starting thrombolysis was 40 +/- 20 minutes; mean delay before admission to the coronary unit was 3 h/45 min. In-hospital time before thrombolysis was one of the lowest in the literature and shows the efficient organization of the department. Delay until transfer to the coronary unit was long and is a sign of the paucity of these specialized beds. Therefore, the possibility to perform thrombolytic therapy immediately in the emergency department becomes even more essential.

[Drug-induced toxic hepatitis].

The case is described of a woman with drug hepatotoxicity, who was a psychiatric patient. The case is reported because the diagnosis occurred by a "praecoxfeeling", in fact physician's intuition is a personal structure which is born from same external incitements instead of other. The diagnosis was confirmed by clinical tests and by subsequent clinical research.

[Praecox feeling in medicine].

In this work the idea of praecox gefüll or praecox feeling is resumed by H. C. Rumke in 1941 and by Minkowski in 1968 for patient with schizophrenia. The diagnosis is not done only by patient's examination and by symptoms, but also by diligent examination which the psychiatry does about himself. To perceive one and to diagnose by praecox feeling is a personal ability, but it is a training with ourselves: to be sensible of the "effect" of disease in us. The praecox feeling, attributed in psychiatry, may be expanded in other medical areas. Case report gives evidence about this.

Enhanced release of atrial natriuretic factor during exercise-induced myocardial ischaemia in patients after acute myocardial infarction.

To determine whether acute myocardial ischaemia induced by dynamic exercise can lead to changes in plasma levels of atrial natriuretic factor, we performed symptom-limited bicycle electrocardiographic tests in 20 males with recent acute myocardial infarction and in 8 control males. Ten patients developed exercise-induced myocardial ischaemia and 10 patients did not. There were no significant differences between the two groups with regard to age, site of myocardial infarction, urinary sodium, atrial sizes, radionuclide left ventricular ejection fraction, workload, baseline and peak-exercise heart rate, baseline and peak-exercise rate-pressure product, duration of exercise. Also baseline atrial natriuretic factor concentrations were similar in both groups (ischaemic patients: 34.51 +/- 15.73 pg/ml; nonischaemic patients: 27.17 +/- 8.74 pg/ml, NS), while peak-exercise atrial natriuretic factor concentrations were higher in patients with exercise-induced myocardial ischaemia (112.31 +/- 35.5 pg/ml) than in the others (80.46 +/- 23.43 pg/ml) (P less than 0.05). After 15 minutes of recovery, plasma atrial natriuretic factor levels were still raised only in the ischaemic patients (63.3 +/- 15.44 pg/ml, P less than 0.01), returning to baseline after 30 minutes in both groups. In control subjects, the behaviour of atrial natriuretic factor resembled that of the patients without exercise-induced ischaemia, with a significant increase at peak-exercise (from baseline levels of 23.1 +/- 10.5 pg/ml to peak-exercise levels of 91.3 +/- 14.5 pg/ml, P less than 0.0005) and a rapid return to baseline levels after 15 minutes of recovery (28.5 +/- 10.6 pg/ml, NS).(ABSTRACT TRUNCATED AT 250 WORDS)

Antiplatelet treatment with ticlopidine in unstable angina. A controlled multicenter clinical trial. The Studio della Ticlopidina nell'Angina Instabile Group.

We conducted a controlled multicenter trial with central randomization and evaluation of events under blind conditions involving 652 patients with unstable angina. Patients were treated either with conventional therapy alone (group C) (n = 338) or with conventional therapy combined with an inhibitor of platelet aggregation, ticlopidine 250 mg b.i.d. (group C + T) (n = 314). Patients were assigned randomly within 48 hours of admission and followed up for 6 months. With the "intention-to-treat" approach, the primary end points, vascular death and nonfatal myocardial infarction, were observed in 13.6% of the patients in group C and in 7.3% of the patients in group C + T, which is a reduction in risk of 46.3% (p = 0.009). Vascular mortality was 4.7% in patients in group C and 2.5% in patients in group C + T, which is a reduction in risk of 46.8% (p = 0.139). The risk of nonfatal myocardial infarction was reduced by 46.1% (p = 0.039), with a frequency of 8.9% in patients in group C and 4.8% in patients in group C + T. New Q wave myocardial infarction occurred with a frequency of 6.8% in patients in group C and 3.8% in patients in group C + T, which is a reduction in risk of 44.1% (p = 0.091). Fatal and nonfatal myocardial infarction was 10.9% in patients in group C and 5.1% in patients in group C + T, which is a reduction in risk of 53.2% (p = 0.006). These findings confirm the importance of platelets in the pathogenesis of unstable angina and the usefulness of antiplatelet treatment for the prevention of cardiovascular events.

[Monitoring of respiratory exchange during ergometric test in patients with heart failure: current aspects and prospects].

The current techniques of respiratory gas-exchange monitoring during stress testing in patients with congestive heart failure have provided new physiopathologic and clinical data. The "breath-by-breath" measurement of oxygen consumption and carbon dioxide production and the evaluation of the relationship between these parameters and respiratory volumes, allow to determine both ventilatory and metabolic responses during exercise, thus giving a precise estimate of the effective cardiopulmonary functional capacity. The demonstration of peripheral vascular and metabolic abnormalities by these techniques have provided new insights into the mechanism of dyspnea and fatigue in patients with heart failure. Although the relationship between respiratory and metabolic parameters and hemodynamics has been extensively studied, its mechanisms are still unclear. Moreover, controversy still exists as to the link between functional capacity and prognosis. Finally, recent studies on the cardiopulmonary adaptations to exercise training in patients with left ventricular dysfunction, have clearly demonstrated clinical and hemodynamic improvement after conditioning. These data, if confirmed, may provide a new approach in the management of patients with this disorder.

[Holiday heart syndrome: spontaneous reversibility of the electrocardiographic and echocardiographic alterations].

The holiday heart syndrome is characterized by symptomatic arrhythmias more often supraventricular, elicited by alcohol ingestion, typically during the week-end period. After admission, electrocardiographic changes, which disappear in few days, are often reported. A case of an alcoholic with syncopal episodes related to alcohol ingestion is described. In this patient, remarkable changes of ventricular repolarization on the electrocardiogram associated with impairment of ventricular diastolic function on the Doppler echocardiographic study are showed. ECG and echo-Doppler data reversed to normality after few days of alcohol withdrawal.

Lidocaine, mexiletine and propafenone in the treatment of arrhythmias complicating myocardial infarction. A case report.

We describe a case of acute myocardial infarction complicated by atrial and ventricular arrhythmias in which it was possible to verify the effectiveness of lidocaine, mexiletine and propafenone. Intravenous administration of mexiletine was ineffective both on atrial and ventricular rhythm disturbances. The lidocaine therapy reduced ventricular ectopic frequency, but did not prevent the appearance of several paroxysms of atrial fibrillation. Intravenous infusion of propafenone, 11 micrograms/kg per min, after a 1 mg/kg i.v. bolus, immediately and completely suppressed atrial arrhythmias. The increase in infusion rate up to 22 micrograms/kg per min also suppressed ventricular ectopy. This dosage of propafenone did not provoke serious adverse effects in our patient.

Effects of captopril on blood pressure and renin-angiotensin-aldosterone system in hypertensive subjects after inhibition of renal vasodilative system.

The aim of this study is to contribute to the understanding of the probable role of the renin-angiotensin-aldosterone, the kallikrein-kinins and the prostaglandins systems on the various types of essential hypertension and also their contribution to the action of captopril. Nineteen patients, 7 with high and 12 with normal or low levels of plasma renin activity (PRA), have been studied. Captopril (100 mg) was administered in acute dosage, blood pressure was checked for two hours and PRA and plasma aldosterone were assayed. The same trial was repeated after inhibition of prostaglandin-synthetase with indomethacin and kallikrein with trasylol, alternatively, and then with indomethacin and trasylol, contemporaneously. Our results showed that the renal vasodilative system was probably also involved in the mechanism of action of captopril, but that this drug reduced blood pressure mainly through a block of angiotensin II production in both groups of patients. Thus the finding of a normal or low PRA does not justify the conclusion that angiotensin II is not one of the mechanisms responsible for an elevated arterial pressure.
