[Beriberi heart disease]. / Beribéri cardíaco.

A man with chronic alcoholism presenting with recent-onset congestive heart failure and hyperdynamic features. Low arteriovenous oxygen content difference suggested high cardiac output. After 10 days of alcohol withdrawal, rest and balanced feeding the patient was asymptomatic and cardiomegaly subsided. No supplementation of thiamine was required.

[Tachycardiomyopathy induced by atrial fibrillation]. / Taquicardiomiopatia induzida por fibrilação atrial.

A 56 year old woman with a previously normal heart developed severe left ventricular dilation and hypo-contractility after a few weeks of a refractory, high ventricular rate atrial fibrillation. Reduction of heart rate with verapamil resulted in a rapid normalization of myocardial contractility.

[Diet with usual quantity of salt in hospital treatment of congestive heart insufficiency]. / Dieta com quantidades habituais de sal no tratamento hospitalar da insuficiência cardíaca congestiva.

PURPOSE: To study the consequences of a diet with usual salt quantity (non salt-restricted) on hospital treatment of congestive heart failure (CHF), in behalf of a better food intake. METHODS: Thirty-two patients admitted to compensation of class III or IV CHF, randomly allowed to group I (2 g salt per day diet) or II (10 g salt). Hypertensive, renal failure or restrictive syndrome cases were excluded. Oral medication and water intake were standardized; furosemide dosage was adjusted on a daly basis, allowing the study of this drug's requirements in each group. Compensation of CHF was defined as a return to classes I or II without edema. RESULTS: Group I included 14 and group II 18 patients. There was no significant difference between groups respective to the time needed for compensation of CHF (7.5 x 6.6 days, mean) percentual weight loss (12.2 x 10.0%), cumulative furosemide dosage (568 x 599 mg), mean daily furosemide dosage per kilogram of lean weight (1.43 x 1.58 mg/kg/day), and to 24-hour urinary excretion of sodium (241 x 254 mEq) and potassium (38.8 x 53.9 mEq). Small elevations of blood urea and potassium were an uniform trend. There was no significant alteration of plasmatic sodium. Food intake was adequate. There was one death for each group, from causes not directly related to CHF. CONCLUSION: Dietary salt intake did not adversely influence in-hospital compensation of severe CHF in studied group. In selected cases, adoption of a more liberal diet in this aspect may allow the patient a better ingestion of food.

[Fatal active rheumatic disease. Study of 13 necropsy cases]. / Doença reumática ativa fatal. Estudo de 13 casos de necrópsia.

PURPOSE: To study the clinical features of a group of patients with fatal acute rheumatic fever (ARF). PATIENTS AND METHODS: Thirteen patients with ARF, the ages ranged between 4.5 and 25 (mean 14) years. Eight patients were male. Patients were studied in two groups: group A of those 14 year-old or younger (8 cases), and group B of those older than 15 years (5 cases). RESULTS: Clinical presentation was fever and severe heart failure in all patients. In group A, it was the first attack of ARF in 5 patients. The time elapsed between beginning of symptoms and hospital admission ranged between 10 and 90 (mean 40) days. Mitral insufficiency occurred in all patients. The blood leukocyte count was greater than 10000 per mm3 in six cases. Atrioventricular block occurred in one case. Valvular vegetations were detected on echocardiogram in 4 cases. Two patients received antibiotic therapy. Surgical treatment of the valvular heart disease was carried on in one patient. In group B, it was the first ARF attack in 2 cases, the time elapsed between beginning of the symptoms and hospital admission ranged between 4 and 60 (mean 21) days. Leukocyte count greater than 10000 por mm3 occurred in 4 cases. Atrioventricular block was diagnosed in one case. Valvular vegetations on echocardiogram were detected in 2 patients. In two cases, the treatment was antibiotic therapy. Three patients were operated on. CONCLUSION: ARF may still be fatal, even in the first attack or in patients in the third decade of life. Other diagnoses are frequently considered, due to the intense clinical and laboratorial manifestations.

[Malnutrition in dilated cardiomyopathy. Correlation with echocardiographic indices of left ventricular function]. / Desnutrição na miocardiopatia dilatada. Correlação com índices ecocardiográficos da função ventricular esquerda.

PURPOSE: To evaluate the incidence of severe protein-calorie malnutrition in patients with dilated cardiomyopathy (DC), and its correlation with left ventricular contractility. METHODS: Group A--51 patients with DC in decompensated congestive heart failure class III or IV, 36 men, aged 51.9 +/- 15.6 years. Group B--25 patients admitted for elective myocardial revascularization with normal LV contractility, 20 men, aged 57.2 +/- 10.5 years. Tricipital skinfold thickness (TS) and mid-arm muscle circumference (MAMC) were obtained in all patients. Severe protein-calorie malnutrition was defined when both measurements were below the fifth populational percentile (Frisancho tables). In Group Am the echocardiographic left ventricular (LV) diastolic diameter (DD), ejection fraction (EF) and systolic volume (SV) were obtained. Those LV parameters were compared between DC patients with and without severe malnutrition. Correlation analysis were performed between TS, MAMC and LV DD, EF, and SV, in the patients of Group A. RESULTS: Severe malnutrition occurred in 7/51 (13.7%) of Group A, and none in Group B. TS values were of 8.90 +/- 4.47 cm in Gr. A and 23.48 +/- 8.52 in B (p < 0.001). MAMC measured 22.25 +/- 3.13 cm in Gr. A and 23.58 +/- 8.52 in B (p = 0.03), LVEF was of 36.29 +/- 9.43% in severe malnutrition patients and of 37.84 +/- 9.78 in the other patients of Group A (p = 0.70). Conversely, LVDD was of 70.90 +/- 11.3 mm vs. 70.75 +/- 8.54 mm (p = 0.98), and LVSV was of 113.0 +/- 52.7 ml vs. 137.6 +/- 56.8 (p = 0.45), when compared severe malnutrition with the rest of patients of Group A. No correlation was found between TS and MAMC and LV, EF, DD and SV in Group A. CONCLUSION: Severe malnutrition was frequent in patients with DC and heart failure. TS measurements, reflecting caloric reserves, were more affected. Echocardiographic parameters of LV function did not correlate with nutritional status.

[Primary angiosarcoma of the right atrium with a patent foramen ovale and severe hypoxemia]. / Angiossarcoma primário de atrio direito com forame oval pérvio e hipoxemia severa.

A 19-years-old female with a primary right atrial angiosarcoma partially obstructing the tricuspid valve, developed severe hypoxemia due to right-to-left shunting through a patient foramen ovale. This is the first report of such clinical situation with this type of tumor. A complete resection of the tumor was attempted, and the right atrium had to be rebuilt with a bovine pericardium patch. Post-operative cranial, thoracic and abdominal CT scans and bone scintigraphy did not show metastatic spread. Chest radiation therapy was started on the third postoperative week. Chemotherapy was not used. The patient died five months after surgery due to disseminated metastatic disease but no evidence of the tumor was found in the necroscopic study of the heart.

Sudden cardiac arrest due to puerperal transient left ventricular apical ballooning syndrome.

A 37 year old woman with chest pain was admitted to the emergency room 40 days after normal delivery with ventricular fibrillation due to Takotsubo cardiomyopathy.
