[Human cytomegalovirus and congestive cardiomyopathy (author's transl)].

Congestive cardiomyopathy in 3 cases, in which occurrence of human Cytomegalovirus (CMV) infection was demonstrated, is described. In all cases significant rise in total CMV antibodies and in early antigen-antibodies was found: CMV was also isolated from urine and saliva in one, a 13 years old boy, and only from urine in the others two patients, 20 and 26 old men. Immunoglobulin M was raised only in the first case, in which CMV infection was likely in act: instead in the others two CMV infection was late primary or recurrent. The possibility of CMV infection as etiological agent of dilatative cardiomyopathy with congestive heart failure in this 3 cases is, in our opinion, strongly suggestive.

[The electrocardiogram in cardiomyopathies].

The electrocardiogram of 27 patients with congestive cardiomyopathy (CMC), 15 with obstructive (CMO) and 13 with hypertrophic without obstruction (CMH) have been studied. Cardiac catheterization, angiography, coronary arteriography, and, in some cases, echocardiography, were performed. The study was carried out in an attempt to define certain patterns of each CM with emphasis on the ischaemic-like features, as infarct pattern, symmetrical T wave inversion, ST elevation, non-typical troubles of ventricular repolarization and on the electrophysiology of these findings. Suggestive for CMC were: (1) prolonged PR, (2) high frequency of arrhythmias and conduction defects, especially complete left bundle branch block with abnormal left axis deviation, (3) left atrial enlargement and ventricular hypertrophy. Suggestive for CMO: (1) low incidence of arrhythmias and conduction defects, (2) left atrial enlargement and ventricular hypertrophy. Infarct pattern, symmetrical T wave inversion and other ischaemic-like features were equally found in all groups of CM, without any statistical difference. Pathogenesis of cardiomyopathy, particularly of CMH, is discussed, carrying out a review of literature.

[Myocardial infarction in the young: evolution and clinico-coronarographic correlation (author's transl)].

Fifty patients who suffered from an acute myocardial infarction at age 40 or below and underwent coronary arteriography, were studied from 8 to 184 months after the infarction (mean follow-up 56 months). Hyperlipidaemia (60%) and cigarette-smoking (82%) were the most common risk factors, while hypertension and diabetes mellitus were found in 10% of all patients. Thirty-seven patients had two or more risk factors. Preinfarction angina was present in 7 subjects. Death rate was 14% within five years and was related to the severity of symptoms. Out of the patients with normal coronary arteriogram (6 patients) or with a single vessel disease 21 were free of angina and 30 did not suffer a reinfarction. Out of 17 patients with two or more coronary vessel disease, angina was present in 14 and reinfarction was seen in 5.

[The congestive cardiomiopathy. A clinical study of the hypotrophic-hypokinetic forms (congestive) (author's transl)].

Based on classifications proposed by Anglosaxon and French authors who were the first to become interested in the so-called cardiomyopathies of unknown origins, 41 cases clinically classified as hypotrophic-hypokinetic (congestive) cardiomyopathies are presented. After a period of clinical observation, 21 cases were studied hemodynamically, with ventriculography and coronaryarteriography, with phonocardiography (35 cases) and follow-up from some months to 6 years. Post mortem studies were performed in 6 patients, five of whom died of congestive heart failure or thromboembolism and one of sudden death. It was concluded that these entities are hypotrophic-hypokinetic cardiomyopathies with a clinical pattern of congestive heart failure and with unknown aethiologic factors. Treatment as far as indications and efficacy are discussed.

[Aorto-coronary by-pass. Personal experience based on 342 cases operated on between April 1971 and December 1974 (author's transl)].

The authors report on the casuistry of aorto-coronary by-pass operations they performed between April 1971 and December 1974, discussing the criteria which indicate the necessity of operating, the principles of the operative techniques, and the results obtained. Out of a total of 342 operated cases, there was an operative mortality (within 30 days) of 3% in isolated by-pass cases, and 4% if one includes associated operations. In 3,5% of patients, postoperative necrosis was present. Almost the same values were found in the smaller group (66 cases) which underwent urgent by-pass operations. The authors consider that the aorto-coronary by-pass operation is a very useful treatment, both for stable and unstable angina, as long as the anatomo-functional conditions exist.

[Peripartum cardiomyopathy (author's transl)].

Three cases of peripartum cardiomyopathy (CMP PP) are presented. In our opinion this term is more correct than post-partum cardiomyopathy. The study was performed both clinically and hemodynamically; patients were followed up for a long period (in one case up to 14 years). Although there were consistent differences in the rise and development of the disease, the clinical and laboratory results could be put together clearly. In the light of this clinical experience, a wide revision of the literature on the topic was carried out, using the hypotrophic-hypokinetic forms of cardiomyopathy (congestive) as a comparison with peripartum cardiomyopathy, which seem to be clinically correlated.
