hyperthyroidism myocardiopathy

Darío Rueda, Rafael Aguirre, Damián Contardo, Paola Finocchietto, Silvia Hernandez, Horacio di Fonzo
BACKGROUND Takotsubo cardiomyopathy (TM), also called stress myocardiopathy or transient left ventricular apical ballooning syndrome, is characterized by acute left ventricular dysfunction with reversible wall motion abnormalities. TM resembles acute coronary syndrome (ACS) in the absence of coronary artery disease (CAD). In several reports, TM has been described in association with hyperthyroidism, suggesting the potential role of thyrotoxicosis in the pathophysiology. CASE REPORT We present the case of a 34-year-old man with TM associated with hyperthyroidism caused by Graves' disease...

Jaundice related to thyrotoxicosis and not as an effect of antithyroid drugs is a rare complication that usually occurs in the presence of heart failure (HF) or hepatitis. We report a case of a 54-year-old white woman with hyperthyroidism caused by Graves's disease and jaundice despite methimazole suspension. Bilirubin fluctuated at high values, between 30.0 and 52.3 mg/dL, transaminases were slightly increased, on admission ALT = 46 U/L and AST = 87 U/L; coagulation indices and serum proteins were on the lower limit of the normal range with PT 68% and albumin = 2...

Thyrotoxicosis is underdiagnosed because of its low occurrence in series from Africa. The aim of this study was to evaluate the frequency, the demographic data, and the etiological aspects of thyrotoxicosis among hyperthyroidy. Thirty-six patients with thyrotoxicosis (group I) gathered during a period of four years was analysed, as well as 180 hyperthyroidy cases (group II). Cardiothyrotoxicosis was observed with a frequency of 16.6%. The mean age was respectively of 44.5+/-13.3 versus 32.8+/-11.4 years (p<10(-6))...

PURPOSE: To analyze the etiology and the prevalence of risk factors in patients with atrial fibrillation. PATIENTS AND METHODS: Applying an unpaired case controlled study, we examined 300 consecutive patients (143 men) with atrial fibrillation and a mean age of 66 +/- 8 years. This group is compared with a control group of 700 patients (mean age 64 +/- 12 years). RESULTS: In the group with atrial fibrillation the etiology in 32% was arterial hypertension, in 20% coronary heart disease, in 13% valvular heart disease, in 11% heart failure, in 4% hyperthyroidism and in 20% idiopathic...

We describe the case of a young man with Graves Basedow's Disease as the unique cause of congestive heart failure, which after several months of antihyperthyroid therapy not very strictly followed, underwent heart transplantation due to severe ventricular and diastolic disfunction. The relationship between thyroid hypertension and cardiomyopathy is reviewed.

OBJECTIVE: To characterize biochemically and isolate the skeletal and heart muscle cell epitope recognized by the autoantibodies present in the serum of chronically infected Trypanosoma cruzi patients. Secondly, to use that epitope in an immunoenzymatic assay for determining differences in antibody titre among Chagas' and other protozoan and heart diseases and between asymptomatic and cardiopathic chagasic patients. DESIGN: Isolated human skeletal and heart muscle cells were treated with organic solvents, pronase, neuraminidase and sodium metaperiodate before immunofluorescence assay...

Without treatment, about 60% of atrial arrhythmia patients suffer a relapse within 3 months and 70% within one year. Antiarrhythmic treatment intended to reduce this percentage is therefore justified, on condition that it is well tolerated. Several preliminary questions have to be settled before this medical prophylaxis: 1) Justification of antiarrhythmic treatment (sometimes pointless to deal with very occasional episodes); 2) Treatment of the underlying heart disease (valve disease, cardiothyrotoxicosis, etc...
