Hypertrophic cardiomyopathy (HCM) is characterized by the presence of an abnormal hypertrophy of the left ventricle (LV), without dilation, and in the absence of any condition or another cardiac or systemic disease capable of inducing such hypertrophy. This primary or idiopathic hypertrophy can occur with or without dynamic obstruction (induced by exercise) of the LV outflow tract, so in its natural history two fundamental aspects are highlighted: the production of symptoms by blocking the LV outflow tract and the occurrence of sudden cardiac death secondary to ventricular arrhythmias...

This study evaluates the risk factors associated with the diagnosis of chronic chagasic miocardiopathy (CChM) in 115 seropositive individuals to anti-Trypanosoma cruzi antibodies, in Barinas state, Venezuela. Serology was performed with ELISA and MABA; while the CChM diagnosis was established by electrocardiography and echocardiography. A complete clinical history including epidemiological, personal/familiar antecedents and psychobiological habits, plus socioeconomic, psychosocial and alimentary habits interviews were performed for each individual...

AIM: The aim of this paper was to determine the prevalence of extracraneal carotid artery disease in patients with intermittent claudication, to describe classic cardiovascular risk factors in those with hemodynamically significant stenosis and to try to define subgroups at high risk, improving therefore the performance of non invasive testing. METHODS: A prospective descriptive study was conducted, with 146 patients reporting an intermittent claudication of the lower limbs and without a previous cerebrovascular event or carotid surgery...

Cardiac hypertrophy can occur as an adaptative response to increased cardiac workload. Different types of cardiac hypertrophy arise from a combination of genetic, physiologic, and environmental factors. When hypertophic growth of the heart leads to left ventricular dysfunction and heart failure, the response is considered as maladaptive or pathological hypertrophy. After analyzed left ventricular functional and structural changes in rats induced by arterial hypertension, banding of aortic root, isoproterenol administration, or myocardial infarction, as well as in patients with arterial hypertension, aortic stenosis, or hypertrophic miocardiopathy, we found a maladaptive response considered as pathological hypertrophy...

OBJECTIVES: This article summarizes the general experience and results achieved by heart transplantation during 19 years of activity. MATERIALS AND METHODS: Between 1987 and 2005, 439 heart transplantations and 24 cardiopulmonary transplantations were performed by the Cardiovascular Surgery Department of Hospital Universitario La Fe, Valencia, Spain. Indication variation over time, donor/receptor profiles, urgent vs. programmed transplantations and short/long term results over different periods of time were subject to analysis, while correlating the results with changes of surgical technique, myocardial protection and immunosuppression protocols...

OBJECTIVES AND DESIGN: a prospective study to determine the value of transthoracic echocardiography (TTE) in assessing hypotensive patients in a medical/surgical Intensive care Unit (ICU). SETTING: a 16-bed medical/surgical ICU. MATERIAL AND METHODS: patients with hypotension were studied (systolic arterial pressure < 90 mmHg or mean arterial pressure < 60 mmHg, non responsive to fluid therapy in a 30-minute period). TTE was aimed to: exclude severe cardiac dysfunction(abnormalities requiring immediate therapeutic decision); to evaluate other non severe cardiac alterations; to determine cardiac index (CI) and analyse inferior vena cava (IVC)...

The world-wide estimated prevalence of diabetes mellitus for 2025 is of about 300 million, resulting from a higher prevalence of obesity and sedentary lifestyles in the developed world. The group of cardiovascular diseases is responsible for 80% of deaths among diabetic patients. Several authors have suggested that patients with diabetes mellitus have a predisposition to develop a form of cardiomyopathy, known as <diabetic cardiomyopathy>, which is not related to ischemic heart disease or hypertension, and may progress to cardiac failure...

The cardiomyopathies are defined as a primary disease of the myocardium and occur in children as well as in adults. Restrictive cardiomyopathy is the least common type of cardiomyopathy and is characterized by the restriction of ventricular filling. This condition can affect one or both ventricles. The appropriate diagnostic tool includes a detailed clinical record supported by imaging and hemodynamic studies. The purpose of this study was to evaluate adult patients with suspicion of restrictive miocardiopathy of the right ventricle, from the out-patients clinic using echocardiogram, magnetic resonance imaging, and hemodynamic studies and to establish a differential diagnosis with other cardiovascular diseases...

Among the amiodarone-induced thyroid dysfunctions, thyrotoxicosis is the most troublesome and with the highest rate of morbidity and mortality. Treatment consists in the use of a high dose of anti-thyroid drugs and steroids in an isolated form or in combination. Association of several other drugs have been proposed for the treatment of refractory cases. In this study we report the case of a 40 y.o. patient, with a history of idiopatic dilated miocardiopathy, who developed severe amioradone-induced thyrotoxicosis after heart transplantation...

The diagnostic categories of the patients discharged from the "Hospital das Clínicas" of the University of São Paulo in 1989 were arranged according the International Classification of Diseases (I.C.D.) and analysed. In each Group sex, age and the reason of discharge or death was indicated. The data concerning 39,601 cases were provided by the Medical Data Service of the "Instituto Central" of the "Hospital das Clínicas". Only the principal diagnosis was taken into account. In the "Instituto de Psiquiatria" most the patients (55...

We report a 36 years old patient with Sjogren's syndrome, who during her second pregnancy, the product developed a miocardiopathy with complete heart block that was diagnosed in utero at 26 weeks of pregnancy. Simultaneously, laboratory data reported a SS-A/Ro titer of 1:50,000 with positive antiphospholipids antibodies. Patient was subjected three times to plasmapheresis with three blood volume exchange each time. During the procedures, we had monitor the product and no hemodinamic changes were observed. Unfortunately, 25 days later the patient reported absence of fetal movement and by ecosonography and Doppler was not observed fetal movement or cardiac function...

The form of presentation of a new case of Melas Syndrome is described, together with a pathological and neuroimage study, including clinical development over a 3 year period. The usefulness of MR should be underlined here, given clinical doubts, and also normality in the EMG early phases of and the association with obstructive hypertrophic miocardiopathy.

Thirty-three subjects, fourteen of which with normal heart, ten with aortic insufficiency and nine with myocardiopathy, were studied by echocardiography and sfigmomanometric arterial pressure measurements. The ejection fraction EF, the left ventricular equatorial wall stress sigma, the corresponding left ventricular strain epsilon and the ratio E = sigma/epsilon have been determined for all subjects. The mean values of these quantities, at the onset of ventricular systole, for normal hearts are: EF = 0.67 +/- 0...

1. The first case of Chagasic Miocardiopathy with complete immunologic confirmation is described. 2. The clinical, radiological, and electrocardiographic basis of the case were analyzed. 3. The specificity and the sensibility to the different seroimmunologic reactions in the Chagasic Disease was discussed. 4. An emphasis is placed on the fact that Chagas illness is not a rare entity in the Mexican Republic. 5. We recommend that a campaign of serologic investigation is begin to discover the true frequency of this illness...

Seroepidemiologic studies demonstrated that American Trypanosomiasis is highly prevalent among rural communities in Mexico. However, Chagas' disease seems to be a rarity. That could be a wrong concept. In just a few months 5 patients with epidemiological, clinical and immunologic evidence for Chagasic miocardiopathy or miocarditis were identified in our Institution. Their cardiologic findings have been discussed, as well as diagnostic approaches in different stages of the disease.
