RESUMO

RESUMEN Las opciones terapéuticas son limitadas para los pacientes con insuficiencia cardíaca avanzada que se vuelven refractarios a las terapias farmacológicas convencionales. Conocer las alternativas no farmacológicas en el tratamiento de estos enfermos resulta imprescindible en su evaluación integral, y es la segunda opción terapéutica en este grupo de enfermos cada vez más prevalentes.


ABSTRACT Therapeutic options are limited for patients with advanced heart failure who become refractory to conventional drug therapies. Knowing the non-pharmacological alternatives in the management of these patients is essential in their comprehensive evaluation, and it is the second therapeutic option in this group of increasingly prevalent patients.

RESUMO

RESUMEN La insuficiencia o falla cardíaca es una enfermedad cada día más prevalente y precisa de complementarios que no solo confirmen lo presumido clínicamente, sino que también sean útiles en la evaluación pronóstica de quienes la padecen. En ese contexto aparecen en las guías de insuficiencia cardíaca, a inicios del año 2000, los biomarcadores con utilidad práctica. Con indicaciones diagnósticas, pronósticas y evolutivas, en cada momento clínico de esta enfermedad, tanto en fase aguda como crónica, su utilización traza pautas y estrategias en el tratamiento adecuado de estos enfermos. En este artículo de revisión se hace un breve acercamiento al tema.


ABSTRACT Heart failure is an increasingly prevalent disease, which requires additional blood tests that not only confirm what is clinically presumed, but also be useful in the prognostic evaluation of those who suffer from it. In this context, biomarkers with practical utility appeared in the heart failure guidelines, at the beginning of the year 2000. With diagnostic, prognostic and evolutionary indications in each clinical stage of this disease, both in acute and chronic stages, its use draws guidelines and strategies in the adequate treatment of these patients. In this review article, a brief approach to the subject is made.

RESUMO

RESUMEN Se presenta una panorámica de la falla cardíaca ligada a las arritmias y a la muerte súbita, que pueden coexistir, agravarse, o ser causa o consecuencia una de otra. Se discuten los signos eléctricos premonitorios que permiten estratificar riesgo en pacientes con eventos previos, con posible acercamiento a la realidad, y en quienes no los han presentado (la mayoría, los no protegidos), y resulta muy difícil o imposible establecer un pronóstico. Estos signos son numerosos, esquivos, de baja especificidad y sensibilidad, ninguno es absoluto ni despreciable, para interpretarlos se requiere una visión integral. Se discuten las extrasístoles ventriculares como predictoras y desencadenantes de arritmias, de muerte súbita y de miocardiopatía, y la utilidad de los procedimientos ablativos frente a los medicamentosos. Los signos eléctricos son buenos para identificar grandes grupos de riesgo pero no lo son tanto para, dentro del gran grupo de bajo riesgo (la mayoría), identificar los individuos de alto riesgo.


ABSTRACT In this research is presented an overview of heart failure related to arrhythmias and sudden death, which can coexist, worsen, or be cause or consequence of one another. Here are discussed the premonitory electrical signs that allow to stratify risk in patients with previous events, with a possible approach to reality, and in those who have not presented them (most of them, the unprotected ones) and where a prognosis is very difficult, or impossible, to be established. These signs are numerous, elusive, with low specificity and sensitivity, none is absolute or negligible, in order to interpret them, a comprehensive vision is required. Premature ventricular contractions are discussed as predictors and triggers of arrhythmias, sudden death and cardiomyopathy, as well as the usefulness of ablative procedures versus medications. Electrical signs are good for identifying large risk groups but not for identifying high risk individuals inside the large low risk group (the majority).

RESUMO

The immune response is crucial for protection against disease; however, immunological imbalances can lead to heart and digestive tract lesions in chagasic patients. Several studies have evaluated the cellular and humoral immune responses in chagasic patients in an attempt to correlate immunological findings with clinical forms of Chagas disease. Moreover, immunoglobulins and cytokines are important for parasitic control and are involved in lesion genesis. Here, cytokine and IgG isotype production were studied, using total epimastigote antigen on sera of chagasic patients with indeterminate (IND, n = 27) and cardiac (CARD, n = 16) forms of the disease. Samples from normal, uninfected individuals (NI, n = 30) were use as controls. The results showed that sera from both IND and CARD patients contained higher levels of Trypanosoma cruzi-specific IgG1 (IgG1) antibodies than sera from NI. No difference in IgG2 production levels was observed between NI, IND and CARD patients, nor was a difference in IL-10 and IFN-³ production detected in the sera of IND, CARD and NI patients. However, IND patients displayed a positive correlation between IL-10 and IFN-³ levels in serum, while CARD patients showed no such correlation, indicating an uncontrolled inflammatory response in CARD patients. These findings support the hypothesis that a lack of efficient regulation between IFN-³ and IL-10 productions in CARD patients may lead to cardiac immunopathology.

RESUMO

Se estudiaron 1 061 cepas de micobacterias no tuberculosas referidas al Instituto de Medicina Tropical "Pedro Kourí" , en el período de 1985 a 1989. Las cepas procedían de los Centros Provinciales de Higiene y Epidemiología del país. Según los resultados globales obtenidos, la mayoría de las cepas clasificadas se ubican en los grupos III y IV de acuerdo con el criterio de Runyon (54,76 y 36 por ciento , respectivamente). Así mismo las especies de mayor frecuencia corresponden al complejo MAI y M. fortuitum
