[Takayasu arteritis associated with heart valve diseases (pulmonary and aortic) and arteritis (coronary and renal)].
The most severe arteritis due to Takayasu's disease are those related to renal and coronary arteries. The first one because it produces severe arterial hypertension and the second one because it puts the patient in high risk of suffering either myocardial ischemia or infarction. These situations worsen when this entity is associated to valvular heart lesions. The authors present the clinical cases of two female patients with Takayasu's disease. One of them in acute phase of the illness, where coronary arteritis, mild coarctation of the aorta, right pulmonary artery stenosis, and pulmonary valve stenosis were present. The second patient was seen during the remission phase of the disease with obstruction of the left subclavicular artery, renal arteritis, severe arterial hypertension and aortic valve insufficiency. The authors discuss the prognosis of patients with Takayasu's disease associated to valvular heart disease and its role in the etiology of pulmonary valvular stenosis. Finally, the authors point out the importance of recognizing the active and non active phases of the Takayasu's disease in relation of the adequate stage for surgical treatment of the lesions caused by this disease.

[Ruptured aneurysm of the aortic sinus of Valsalva: clinical course, diagnosis, and treatment].
The authors present the clinical cases of 5 patients, with rupture of the aortic Valsalva's sinus aneurysm open to the right chambers, diagnosed clinically, echocardiographically and hemodynamically in the past eight months. Among them, four were males, and one female. Three were treated surgically successfully, one patient refused surgery and another had a sudden death before surgery. The patients showed arteriovenous blood flow shunt, three from the aorta to the right ventricle, and two to the right atrium. One case was associated to an atrial septal defect, and tricuspid insufficiency in another. The authors added a sixth case: a woman, with rupture of the aortic Valsalva's sinus open to the right ventricle, aortic insufficiency and diaphragmatic subaortic stenosis. The authors discuss the embryologic origin of the formation and rupture of the Valsalva's sinus aneurysm as well as the factors that contribute to it's rupture, the natural history of the illness, it's classification, association with other heart disease as well as diagnosis and treatment.

[Volume and function of the right ventricle before and after intraluminal pulmonary valvuloplasty].
With the purpose of studying the right ventricular infundibulum response to the obstruction of the pulmonary blood flow, the authors inform the results of the right ventricular volumes, and function changes before and after pulmonary intraluminal valvuloplasty performed in six adult patients with congenital stenosis of the pulmonary valve. After the valvuloplasty, all right ventricular volumes increased but only slightly, except for the end systolic volume at the right infundibulum, which decreased after valvuloplasty (for alpha = 0.10, p less than 0.10). The ejection fraction of this infundibulum increased after valvuloplasty (for alpha = 0.05 p less than 0.03), while the ejection fraction of the inflow chamber remained unaltered. In the same way decreased the work and power of the inflow tract of the right ventricle, regardless the decreased in the ventricular overload post-valvuloplasty; however, the ratio work vs. end diastolic volume of the right ventricle decreased (for alpha = 0.05, p less than 0.03). The authors discuss these results in relation with the changes produced by the obstruction, acute or chronic, of the pulmonary blood flow on the infundibular wall tension and contractility, whose structure and behavior allow to propose that the function of the infundibulum by means of contraction protects the pulmonary vasculature, against right ventricle hypertension.

[Prognostic indexes in primary dilated cardiomyopathy].
The purpose of this study was to investigate, if besides the hypocontractility, which is the main finding in Primary Cardiomyopathy (PDC) there was some other mechanism in the development of heart failure and if this fact could influence in it's prognosis. We studied 13 patients with PDC in the hemodynamic cardiac laboratory from January 1982 to January 1988, these with systemic arterial hypertension. Coronary heart disease, myocarditis, primary valvular lesion, infiltrative disease, nephropathy, congenital heart disease, diabetes and alcoholism, were excluded. The control group was formed by 12 healthy subjects, which were studied for another purpose. We analyzed nine variables, including ejection fraction, peripheral vascular resistance, systolic and diastolic circumferential stress, left ventricular mass, left ventricular end diastolic and systolic volumes as well as force-velocity and force-fiber length relationship. The patients were followed up from 8 to 60 months (average 39 months). The cases with PDC were divided in two groups, "compensated" and "decompensated". The last ones with low ejection fraction and significantly increases systolic stress. We investigated which was the mechanism of compensation and decompensation through the force-velocity and force-fiber length relation. We found that compensation is associated with great increase of the after-load forces, the more end systolic volume at the end of the systole is not only controlled by the "force", but the decompensation is developed when the hypocontractility is added to the incompetence to compensate the after load. We found that the three deaths in this study had these hemodynamic characteristics, being the cause of death: the presence of heart failure in two patients and ventricular fibrillation in one.(ABSTRACT TRUNCATED AT 250 WORDS)

[Purine metabolism in ankylosing spondylitis: clinical study].
We undertook a prospective study of 23 male patients with Ankylosing Spondylitis (AS) (New York Criteria), 18 HLA-B27 positive and 5 HLA-B27 negative, five of them had hyperuricemia. The following data of evolution were taken into consideration: age at onset of disease, time course of the disease, presence of urolithiasis, heart disease, flares of uveitis. Clinical activity and degree of disability were evaluated every one to 3 months; on each visit, every patient had determinations of serum and urinary uric acid levels, serum and phosphorus, erythrocyte sedimentation rate (ESR), serum protein electrophoresis, as well as X-ray films of the vertebral spine and pelvis. Three groups of patients were detected, all of them with equal age at onset, duration of disease, frequency of B27, peripheral arthritis, and leukocytosis. One group had hyperuricemia (5 of 23 patients, 80% of them HLA-B27 positive) and a lesser degree of clinical activity of the disease (p less than .001, a higher frequency of uveitis (40%, lower levels of serum gammaglobulins (p less than 0.05) and ESR (p less than 0.05), a lesser degree of ankylosis of the spine, and a better functional prognosis than the other groups. Another group (8 of 23 patients, 75% of them were HLA-B27 positive) had normouricemia and hyperuricosuria, and showed a higher frequency of fever (50%), an abnormal urinalysis, and urolithiasis (25%).

[Usefulness of endomyocardial biopsy in myocarditis and dilated cardiomyopathy].
Through an endomyocardial biopsy (EB) we studied 30 patients, 15 of them with suspicious clinical diagnosis of myocarditis (M) and 15 with dilated cardiomyopathy (DC). In only 4 (26%) out of the 15 patients with M we found inflammatory changes in the biopsy. By serendipity a metastatic malignant tumor was found in one patient. In 9 (60%) out of the 15 cases with DC the histological report was compatible with interstitial fibrosis, hypertrophic myofibrils, myositic degeneration and atrophy and in 2 of these patients inflammatory cell infiltration. In all patients in whom we found these inflammatory process the illness was present for less than 6 months. We concluded that in only a limited percentage of patients with the clinical diagnosis of M inflammatory changes are present (26% in our study). In patients with DC the information given in few cases (13%) an inflammatory cell infiltration could be seen. The probability of finding inflammatory changes is higher if the duration of the disease is less than 6 months. It is important to have in mind that through this method an occult pathology could be discovered.

[Circadian rhythm in myocardial infarct].
In order to determine if the beginning of the Myocardial Infarction (MI) is at random along the day or if it follows a circadian rhythm, we analyzed the clinical charts of 819 patients admitted to the Coronary Care Unite. Among them, 645 were male and 174 female. It was established that the beginning of the MI follows a circadian rhythm with maximal frequency between 8 and 9 a.m. and minimal at 0 hours (p greater than 0.01). This rhythm is sex independent. In patients younger than 45 years as well as those who received beta-block agents in less than 24 hours previous the MI no circadian rhythm was observed.

[Myocardial infarction with normal coronary arteries].
We retrospectively studied 36 cases of myocardial Infarction (MI) with normal coronary arteries, which had been obtained from a total of 538 patients with MI admitted to our Hospital in the last 3 years. All patients had coronary angiogram and left ventriculogram. The following data was reviewed: age, sex, coronary risk factors, clinical picture, short and long term follow up. The angiography findings were correlated. The average age of the patients was 42 years, 75% were male and 25% female. The 36 cases represent 7% of the total MI. Cigarette smoking was the only important risk factor. MI was the first manifestation of ischemic heart disease in 94% of the cases. The ejection fraction was normal in 94%; 27.6% presented some complication during the acute event. In the long term follow; up to 88% of the patients are asymptomatic. The physiopathologic mechanisms are analyzed.

[The heart and rheumatoid arthritis. Prospective study of 100 cases].
We studied one hundred consecutive patients with rheumatoid arthritis from the cardiological point of view through non invasive methods to detect the frequency of cardiovascular complications. Seventy three (73%) were females and twenty seven (27%) males. Mean age, 48.6 years. Mean age of presentation of the disease, 34.2 years. Mean age of duration of the illness, 21.8 years. Fifty seven per cent had some type of cardiopulmonary complication. Clinically 52 per cent referred some type of cardiopulmonary symptoms. The physical examination was abnormal in 27 per cent. Rheumatoid factor (Waaler-Rose) was positive in 82 per cent. The cardiac X ray series was abnormal in 33 per cent, the resting electrocardiogram in 48 per cent and the M mode echocardiogram in 52 per cent of the cases. The complications detected were: pericardial effusion (21%); pleural effusion (9%); pulmonary fibrosis (6%) which represents a higher incidence of previously reported in the literature; congestive heart failure (10%); valvular lesion (9%) among those are included six patients with valvular heart disease of non detectable etiology; ischemic heart disease (8%); myocarditis (6%); rythm disturbances (22%) and conduction defects (20%) including a 46 year old female patient who developed a complete AV block during an exacerbation of her illness, requiring the insertion of definitive pacemaker. Our results showed that some of the detected lesions are in part more frequent and severe than those reported in the literature, probably due to, that on one hand their search was intentional and on the other, our group was constituted by with severe and long standing rheumatoid arthritis.

[Cardiovascular changes in acromegaly. Prospective study].
We present 38 acromegalyc patients who were studied by non invasive methods to assess the frequency of cardiovascular complications. Seventy one percent of the cases presented some type of cardiovascular alteration. In 68% we observed left ventricular hypertrophy by echocardiography which was the most sensitive method to detect it. In 71% we obtained abnormal electrocardiograms, mainly because of conduction disturbances, being right bundle branch block the most frequent. Half of the cases had pulmonary fibrosis and chronic bronchitis. Arterial hypertension was present in 32%. Diabetes mellitus in 21%. Only 2 cases had coronary heart disease. In 37% of the patients who underwent hypophisectomy we observed regression up to 90% of the cardiac complications except for left ventricular hypertrophy and pulmonary fibrosis. None of the patients has died.
