Cardiovascular Disease in Latin American Women Gaps and opportunities

Abstract Cardiovascular disease (CVD) remains the leading cause of death in women. This review will address the known disparities in cardiovascular care concerning diagnosing and treating of heart disease in Latin American (LA) women. Gender-specific differences regarding the incidence, treatment, and outcomes of common cardiovascular pathology are increasingly recognized. Today, we identify that women have cardiovascular risk factors (CRFs), specifying the traditional, emerging, unique, or sex-specific determinants and the social and biological determinants that play a leading role in the prevention of CVD. The purpose of this article is to review the literature on cardiovascular disease in LA women, focusing on ischemic heart disease (IHD), valve disease (VD), heart failure, and cardiac rehabilitation (CR), where disparities continue to affect outcomes. Understanding the unique cardiovascular risk profile and barriers to optimal treatment outcomes in women is imperative to eliminate the current disparities in CVD.

Fibrosis endomiocárdica / Endomyocardial fibrosis

Resumen Las miocardiopatías son trastornos intrínsecos del músculo cardíaco. Presentan fenotipos diferenciales que determinan su clasificación; estos son: dilatada, hipertrófica, restrictiva, displasia arritmogénica del ventrículo derecho y no clasificadas. Las miocardiopatías restrictivas se caracterizan por ventrículos de tamaño normal, con grosores de pared normales o ligeramente aumentados, paredes rígidas, disfunción diastólica severa y llenado restrictivo con presiones elevadas. Una de las formas más comunes de miocardiopatía restrictiva es la fibrosis endomiocárdica la cual es endémica en algunas zonas tropicales especialmente en África (países de bajos ingresos), pero en nuestro medio hay pocos reportes de aparición. Su etiología es desconocida, aunque existen diversos mecanismos que han sido involucrados en su fisiopatología. Su diagnóstico se basa en estudios imagenológicos (ecocardiograma transtorácico y resonancia magnética nuclear cardíaca). El pronóstico es muy pobre, y usualmente se diagnostica en etapas muy avanzadas de la enfermedad. Se describe el caso de una paciente femenina, adulta media, que debutó con cardiopatía restrictiva, cuyo diagnóstico final fue fibrosis endomiocárdica.

Abstract Cardiomyopathies are intrinsic conditions of the cardiac muscle. They present differential phenotypes that determine their classification. These are: dilated, hypertrophic, restrictive, arrhythmogenic right ventricular and unclassified. Restrictive cardiomyopathies are characterised by larger than normal ventricles with normal or slightly enlarged thickness of the walls, rigid walls, severe diastolic dysfunction and restrictive filling with high pressures. One of the most common restrictive cardiomyopathies is endomyocardial fibrosis, which is endemic to some tropical areas, especially Africa (low income countries), but there are few reports of its occurrence in our environment. Its aetiology is unknown, but there are several mechanisms that have been involved in its pathophysiology. Its diagnosis is based in imaging studies (transthoracic echocardiogram, cardiac nuclear magnetic resonance). Prognosis is very poor, and it is usually diagnoses in the latest stages of the disease. The case of a female, average adult patient that debuted with restrictive cardiomyopathy with a final diagnosis of endomyocardial fibrosis is described.

Miocarditis eosinofílica como causa de disfunción ventricular izquierda reversible / Eosinophilic myocarditis as a cause of reversible left ventricular dysfunction

Resumen La miocarditis eosinofílica es una entidad poco difundida ya que su diagnóstico histopatológico se realiza en casos de mayor severidad, donde la biopsia endomiocárdica es mandatoria. No obstante, dado que esta entidad suele superponerse a muchas patologías: las infecciosas, las inmunológicas, o asociadas a la hipersensibilidad y esto se asocia con la reversibilidad, es importante tenerla presente como entidad nosológica en cuadros agudos de la disfunción ventricular izquierda. Puede o no estar asociada a la eosinofilia periférica, su ausencia no descarta la enfermedad. Se presenta un paciente joven (35 años de edad), con un cuadro clínico de la falla cardiaca aguda que progresa rápidamente a choque cardiogénico con poca respuesta al manejo inicial instaurado (inodilatadores, vasopresores), requiriendo el uso de soporte circulatorio extracorpóreo. Como antecedente: la reciente finalización del tratamiento para leishmaniasis mucocutánea, con antimoniato de meglumina (glucantime). Informe del servicio de patología: miocarditis eosinofílica. Se logra el destete del soporte circulatorio, presenta mejoría de la función sistólica del ventrículo izquierdo con recuperación total del cuadro clínico. Este caso es relevante en cuanto a diagnóstico de disfunción ventricular aguda, con una asociación previamente no descrita con antimoniato de meglumina (glucantime), nos recuerda la importancia de realizar: la biopsia endomiocárdica para definir la etiología, la toma de decisiones de terapias avanzadas, conociendo que en ciertas circunstancias puede presentarse reversibilidad de la disfunción miocárdica y mejoría del cuadro clínico.

Abstract Eosinophilic myocarditis is a little-known entity as its histopathological diagnosis is conducted in the most severe cases, where an endomyocardial biopsy is mandatory. However, because this condition is usually overlaps with many pathologies -infectious, immunological, or associated to hypersensitivity, and this is related to reversibility- it is important to keep it in mind as a nosological entity in acute presentations of left ventricular dysfunction. It may or may not be associated to peripheral eosinophilia, though its absence does not rule out the condition. A case of a young male patient (35 year-old) with clinical features of acute cardiac failure which progresses rapidly into cardiogenic shock with low response to initial management (inodilators, vasopressors) requiring the use of extracorporeal circulation support is presented. Previous history: recent completion of treatment for ucocutaneous leishmaniases with meglumine antimoniate (glucantime). Pathology service report: eosinophilic yocarditis. Weaning from circulatory support is achieved, presenting an improvement of systolic function of the left ventricle with complete recovery of the symptomatology. This case is relevant due to the diagnosis of acute ventricular dysfunction with an association with meglumine antimoniate (glucantime) that was previously not described. It reminds of the importance of carrying out an endomyocardial biopsy in order to define the aetiology and the decision-making on advances therapies, knowing that in some circumstances there can be a reversibility of the myocardial function and an improvement of the symptomatology.
