An observation of adrenergic myocarditis with clinical and electrical signs of coronary failure is reported. The patient had electrical and enzymatic manifestations of acute anteroseptal necrosis, complicated at the acute stage by complete atrioventricular block and fatal vasoplegic circulatory collapse. Post-mortem examination showed obstructive atherosclerosis of the anterior interventricular artery without anatomic signs of infarction. Pathogenesis of this coronary failure is discussed. In this case, functional coronary insufficiency produced by catecholamine release was associated with coronary atherosclerosis.

Although nonspecific pericarditis, myocarditis, valvulitis, and coronary arteritis are known as cardiac lesions that accompany rheumatoid arthritis (RA), there have been few reports of the occurrence of clinically severe valvular disease. We report here the case of 69-year-old man with a 25-year history of RA who died of acute left-sided heart failure complicating to aortic steno-insufficiency and angina pectoris. Autopsy findings revealed the coincidence of a congenital bicuspid aortic valve with chronic inflammation, fibrosis and calcification; eccentric hypertrophy and myocardial fibrosis of the left ventricle; 75% luminal narrowing of the proximal portion of the coronary artery due to atherosclerosis, and narrowing of the small arteries of the cardiac muscle due to angitis. It is deduced that the coronary artery lesions, aortic valve lesions and myocardial lesions were aggravated by the bicuspid aortic valve, changes with ageing and corticosteroid therapy.

Gated cardiac magnetic resonance (MR) images were obtained in two normal volunteers and 21 adults with a variety of cardiovascular abnormalities. The images were correlated with data from clinical examinations, electrocardiograms, and cardiac catheterization. Gated cardiac images were superior to nongated images. Combined cardiac and respiratory gated images were superior to images obtained with cardiac gating only, but acquisition time was longer. Portions of the coronary arteries were visualized in seven of 23 examinations (30%), and subacute and old myocardial infarcts were seen in five of nine patients (55%) as areas of thinned myocardium. No signal changes were observed in the patients with subacute infarctions or the patient with myocarditis. Coronary atherosclerotic lesions were not visualized in any of the patients. Normal cardiac anatomy (chambers, valves, and papillary muscles) was well visualized. Examples of aortic stenosis and atherosclerosis of the abdominal aorta are shown.

A rare case of tuberculous myocarditis, miliary type, in hematogenic-disseminated tuberculosis of lungs and liver is reported. Some morphological characteristics of tubercules in myocardium require a broad differential diagnosis with idiopathic granulomatous myocarditis, sarcoidosis, lues and brucellosis. Tuberculosis was in combination with isolated heart defect-- insufficiancy of aortic valve, hypertonic disease, atherosclerosis, dissecting aneurysm of ascending aorta and left coronary artery of the heart, complicated by a rupture during the cardiac operation.

A review of the occurrence of pre-existing disease found in 809 military, professional, and private aircrew killed in 525 flying accidents in the United Kingdom from 1955 to 1979. In the author's experience, the most common diseases encountered included coronary atherosclerosis, myocarditis, pathology of the liver, psychiatric or adverse medical histories, upper respiratory tract infections, and defective vision. The role of these diseases in accident causation and the need for caution in the interpretation of asymptomatic disease is discussed. The importance of histological examination in death due to trauma and of circumstantial evidence is emphasised.

Human cytomegalovirus (HCMV) can establish lifelong persistence after primary infection with reactivation occurring as a result of immunosuppression. There is much evidence that molecular interactions between the immune system and the HCMV are responsible for immune escape. HCMV in many cells especially in mononuclear blood cells during latency are frequently the source of transmission and spreading and results in a variety of disorders. In this review some data about acute infection in immunocompetent host (mononucleosis, hepatitis), about intrauterine HCMV infection, about infection and endogenous reinfection in bone marrow and solid organ transplant recipients (pneumonitis) and about HCMV disease in AIDS patients (encephalitis, neuropathy, retinitis, colitis) are investigated. Moreover, HCMV associated vasculitis is described in patients with myocarditis, rheumatoid arthritis or polyradiculopathy. HCMV could play an important role in atherosclerosis. Several types of human malignancy have been linked to HCMV and it has been shown that HCMV ie genes upregulate expression of cellular oncogenes. The diagnosis of HCMV infection is carried out by viremia in cell culture using immediate early antigen staining, by antigenaemia which appears to be an early quantitative and predictive tool, by HCMV DNA detection using hybridization and PCR, and by IgM and IgG antibody evaluation. Two antiviral drugs are used for treatment: ganciclovir and phosphonoformic acid; few resistant clinical isolates have been reported. Specific gammaglobulin activity is discussed. HCMV vaccine is not available.

To assess the cardiological status of patients with long-term lupus nephritis we evaluated 30 patients (mean age 43 +/- 11 years) with lupus nephritis lasting from at least 10 years (mean 15 +/- 5 years). At the time of cardiological evaluation the mean plasma creatinine was 132.6 +/- 11.1 mumol/l and in 28 patients lupus had been quiescent for at least 3 years. Fourteen patients (46.6%) showed one or more cardiac abnormalities: 10 had valvular lesions (1 verrucous endocarditis, 9 thickening and stiffness of one or more valves)--4 patients had regional myocardial akinesis as a consequence of a previous cardiac infarct (one had valvular abnormalities too). One patient had pulmonary hypertension probably secondary to pulmonary vasculitis. No patient had pericarditis. These cardiac abnormalities proved to be statistically correlated with the number of ARA criteria (p = 0.045), the number of lupus flares (p = 0.004), the serum levels of cholesterol (p = 0.04) and of triglycerides (p = 0.025) as well as the duration of hypercholesterolemia (p = 0.005) and of hypertriglyceridemia (p = 0.007). In conclusion, in patients with long-term lupus nephritis cardiac lesions are frequent. The main lesions are non-verrucous valvulopathy (probably a consequence of healing verrucous endocarditis) and cardiac infarct (caused by an accelerated atherosclerosis). On the contrary cardiac lesions caused by active lupus as pericarditis, myocarditis and verrucous endocarditis are rare.

Molecular biology has given a strong impact on cardiovascular medicine, not only clinical but also laboratory medicine. cDNA cloning and analysis of gene structures encoding functional proteins or peptides in the cardiovascular system provided insight into molecular mechanisms underlying heart diseases or atherosclerosis. Nucleotide or amino acid sequences for these molecules are useful information for manufacturing bioactive peptides or developing immunoassays. These cDNA clones or genes are useful molecular tools diagnosing patients with high risks for cardiovascular diseases. Recent advances in this field have been made in identification of point mutations of many genes important for cardiovascular functions, including LDL receptors in familial hyperlipidemia, cardiac myosin heavy chain genes in familial hypertrophic cardiomyopathy, mitochondrial DNA in mitochondria cardiomyopathy, or dystrophin genes in secondary cardiomyopathy. Molecular probes are further used in detection of microorganisms causing myocarditis. These progresses that have been made in laboratories of basic researchers will be introduced into clinical medicine and expand the field the laboratory medicine is involved.

We describe the cardiovascular abnormalities found at autopsy in patients with AIDS and a description of the opportunistic infections in these cases studied between January 1988 and August 1993. There were 51 cases with such diagnosis. Pericardial effusion appeared in 9, pleural effusion in 7, myocarditis in 5, 7 with pericarditis, endocarditis in 6, left ventricular hypertrophy in 20, right ventricular hypertrophy in 21 and evidence of atherosclerosis in 15. Thus, data of cardiovascular damage was present in 42.7% of our patients. The cardiovascular abnormalities in this group are common, in contrast to the paucity of clinical findings. Diagnosis of cardiac pathology was made in only 12% of them. So in every case with diagnosis of AIDS, a careful clinical examination and cardiac diagnostic oriented tests must be done for detection of these abnormalities.

Clozapine is a high-dose neuroleptic, which is recommended only for those cases in which patients have failed to respond adequately to standard antipsychotic drugs. This report describes a 45 year old man with ischaemic heart disease who died of cardiogenic shock 11 days after starting treatment with clozapine. Autopsy showed apart from coronary atherosclerosis and interstitial fibrosis a considerable infiltration of eosinophilic granulocytes in the myocardium suggesting myocarditis as the cause of death.
