[Epidemiological and clinical observations on 300 cases of primary myocardiopathy].

In the period from 1968 to 1977, in the Departments of Cardiology of the S. Camillo Hospital, a study has been made about 200 cases of Congestive Cardiomyopathy (MPC) and 100 about hypertrophic obstructive (MP0). Congestive cardiomyopathies constitute 1.5% of hospitalizations with a constant trend in the long run. In comparing these two forms, Authors have noticed some differences in the symptomatology of clinical and instrumental signs: 1) in case of MPO prevail angina, syncope, ejection systolic murmur, left ventricular overload in the ECG; 2) in case of MPC they find more frequently heart failure, embolism, diastolic gallop, cardiomegaly, A/V and intraventricular conduction disturbs. The AA. conclude, in accordance with Goodwin's classification, that there is not an uniformity of these two kinds of cardiomyopathies.

[Psychological and occupational repercussions of myocardial infarct].

The AA. studied the psychological and working consequences of the myocardial infarction in a group of 147 patients outlived more than two years. 50% of them showed mood disturbances, 40% did not restarted of work and 20 worked again moderately. The interruption of the work had psychological reason in 32% of cases and economic reasons in 26%. The 38% of the subjects was pensioned and the 25% received a pension through work foult. According to the INPS data, in Italy, every year, 1000,000 pension claims, for arteriosclerotic cardiopathy or myocardial infarct are made. Pensions are granted in 99% of cases. The pension claims diminish from the North to the South of Italy and are lower among traders and farmers. The importance of psychological rehabilitation is confirmed by the resumption of work in 92% of the cases among the railway workers, that have a good medical assistance.

[The course of hypertrophic obstructive cardiomyopathy. A preliminary study of 40 cases (author's transl)].

The course of hyperthrophic obstructive cardiomyopathy in 40 patients was studied. The average follow-up of the patients (anamnestic and prospective) was 8 years. The age of the first diagnosis, the age of the first observation and the age of the detection of the first symptom, were considered. A prospective follow-up study was carried out in 31 patients, the average period of observation being 8 years. Functional capacity modifications, symptoms, clinical and electrocardiographic signs and the mortality rate were analyzed. Functional class unchanged in the most part of the patients; the overall mortality was 16% with high incidence of sudden and unexpected death. From our results it appeared that the prognosis could be related to the old age, heart failure and arrhythmias.

[A study of the natural evolution of hypertrophic obstructive cardiomyopathy. Analysis of 100 cases (authors' transl)].

The authors present a study of the course of hypertrophic obstructive cardiomyopathy (C.I.O.), diagnosed both through noninvasive (52) and invasive (48 cases) techniques, in 100 patients. The average period of observation (prospective and retrospective) was 8.2 years; in 68 cases prospective inquiries were carried out over an average period of 4.6 years. In 80% of the cases the first symptoms occurred when the patient was under 40, while the first diagnosis and period of observation usually took place between the ages of 20 and 50. The results of this study confirm that CIO is an illness with a slow evolution; the following facts emerge: a) considerable stability of the symptoms; b) low yearly mortality rate (1.8%); c) high rate of survival 10 years after the first onset of the symptoms. The most frequent cause of death is usually sudden, which leads to the supposition that one of the most important elements for prognosis is the identification and treatment of arrhythmias.

[The carotidogram in the diagnosis of the juxtavalvular fibrotic aortic stenosis. Report of 47 cases (author's transl)].

The morphological aspect of the carotid pulse has been under study in 47 cases of juxtavalvular aortic stenosis previously confirmed through hemodynamic and surgical examinations. The study included 39 cases of subvalvular fibrous stenosis (subaortic fibrous stenosis) (SAsV) and 8 cases of supravalvular annular aortic stenosis (S AsV). In 75% of both SAsV and SAsV cases the carotid pulse showed a rapid ascent and a finely notched apex, while in 25% of the cases it followed the pattern of a typical valvular stenosis. This is more obvious for the left carotid artery. The morphology of the carotid pulse resulted as independent from the aortic ventricular gradient, but, on the other hand, connected with the simultaneous stenotic involvement of the valvular cusps. The sign possesses not only high sensitivity but also high specificity with regard to juxtavalvular aortic stenoses because it has only been met with in 2 cases of valvular aortic stenosis. The pathophysiological explanation remains as yet obscure.

[Pacemakers: concerning check-ups (author's transl)].

The Authors have re-examined their case histories of 1503 patients who have had 2459 pacemakers implanted and who have undergone check-ups as outpatients. All the complications which have arisen from 1967 to the present have been taken into consideration. The total number of complications has been found in 355 patients with 14% of the total number of pacemakers and they have been subdivided into 3 groups: 1st group: complications arising during the stay in hospital (110); 2nd group: complications arising after discharge from hospital and discovered by the patient (239); 3rd group: complications found casually during outpatients' check-ups (6). Of the complications found after discharge, 97% belong to the second group and only 3% to the third group. 657 substituted pacemakers have also been taken into consideration with the purpose of finding out the parameters which showed up as the battery was running down. Out of 145 pacemakers substituted because of flat batteries, 130 (90%) have shown brusque variations in the frequency of stimulation, while only 15 (10%) have shown variations in other parameters (width, length of impulse, etc). The Authors therefore retain that a periodic outpatients' check-up of the pacemakers is of little use as regards the patients' safety and the complete utilization of the device, while they advise that the patient be educated so as to be able to carry out his own daily control of the pacemaker.

[Analysis of Luciani-Wenckebach periodism in A-V node. I. Typical features (author's transl)].

Electrocardiograms of 20 patients developing Wenckebach A-V block duting atrial pacing and 20 with spontaneous Wenckebach block were reviewed to determine the frequency of typical features of classical Wenckebach periodicity. Few cases only met all six typical criteria. Cases with long cycles with conduction ratios of 5/4, with Wenchkebach point less than 130 min, and with first greater than A-H 110 msec were the most likely to show typical features. The implications of these observations are discussed on the basis of modern hypothesis of electrophysiological mechanisms of Wenckebach periodism.

[Analysis of the Luciani-Wenckebach phenomenon in the A-V node. II. Relationship between conduction and recovery times].

We have studied 20 cases Wenckebach A-V block by atrial pacing. The relationships between conduction time and recovery time of N. AV Wenckebach point, basal A-H time and A-H time of first cycle beat were analysed. No correlation was found between W point, basal A-H and A-H of the first beat by analysing the A-H = f (H-A) we found different curves which occur when the first A-H is longer or shorter than 110. These data were discussed on the basis of modern hypotheses of electrophysiological mechanism of Wenckebach periodism.
