Factors associated with orthostatic hypotension in adults: the ELSA-Brasil study.
This study aimed to investigate factors associated with orthostatic hypotension in 14,833 individuals 35-74 years of age. This was a cross-sectional study of baseline data (2008-2010) from the Longitudinal Study of Adult Health (ELSA-Brasil). Postural testing was performed after 20 minutes resting in supine position and active adoption of orthostatic posture. Blood pressure was measured in supine position and at 3 minutes in orthostatic position with an oscillometer (HEM 705 CP, Omron, São Paulo, Brazil). Orthostatic hypotension was defined as a drop of ≥ 20mmHg in systolic blood pressure and/or a drop of ≥ 10mmHg in ...

Chagas disease, cardioembolic ischemic stroke, INR control and bleeding
This report describes the history of this Brazilian engineer, also known as the King of Coffee, who achieved enormous business success and fortune in the late nineteenth century. In 1890, during the inspection of his farm, the world's largest coffee plantation at that time, he fell from a carriage, which left him a hemiplegic. This forced him to sell the farm and move to France for treatment. Before his death two years later, he gave his 18-year-old son bits of advice, and distributed his inheritance, which allowed Alberto to study in Paris and finance his experiments that would culminate in the development of the airplane...

Ischemic stroke and infectious diseases in low-income and middle-income countries
Purpose of review To address the important relationships between stroke and infection, focusing on the most frequent infections found in low-income and middle-income countries. Recent findings Stroke is one of the leading causes of mortality and disability worldwide, with a great proportion of the stroke burden occurring in low-income and middle-income countries. Infectious diseases are still a great health problem in developing countries and it is possible that the proportion of infection-related strokes is greater in these nations. Infectious diseases and stroke have a bidirectional relationship. Common infections m...

Electrocardiogram in Chagas disease
Abstract Since the initial descriptions of Chagas cardiomyopathy (ChCM), the electrocardiography has played a key role in patient evaluations. The diagnostic criterion of chronic ChCM is the presence of characteristic electrocardiographic (ECG) abnormalities in seropositive individuals, regardless of the presence of symptoms. However, these ECG abnormalities are rarely specific to ChCM and, particularly among the elderly, can be caused by other simultaneous cardiomyopathies. ECG abnormalities can predict the occurrence of heart failure, stroke, and even death. Nevertheless, most prognostic studies have included Chagas dise...

Mortality and Stroke Recurrence in a Rehabilitation Cohort of Patients with Cerebral Infarcts and Chagas Disease
Conclusions: Cardiac conditions did not correlate with mortality or recurrence. Age was a protective factor against recurrence, probably due to cumulative risk of IS over time, while initial mRS was associated with both outcomes. Treating diseases such as DM and bladder dysfunction, and early treatment to reduce the initial mRS could potentially prevent both outcomes; also, establishing a correct etiological diagnosis is important.Eur Neurol 2018;79:177 –184

Comments on Etiological Classification of Stroke in Patients with Chagas Disease Using TOAST, Causative Classification System TOAST, and ASCOD Phenotyping
We have read with great interest the article by Bezerra et al,1 in which an etiological classification of stroke in patients with Chagas heart disease using different systems is presented. By studying a tertiary referral center population composed of 32 patients with Chagas disease with stroke, the authors were able to show that although cardioembolic str oke affects the majority of patients, atherosclerosis and small-vessel occlusion still were important causes of stroke in patients with this condition.

Etiological Classification of Stroke in Patients with Chagas Disease Using TOAST, Causative Classification System TOAST, and ASCOD Phenotyping
Cardioembolism is considered a major pathophysiological mechanism in patients with ischemic stroke (IS) and Chagas disease (CD). However, a previous study reported that other stroke subtypes are present in more than 40% of CD patients according to the TOAST classification. Therefore, the aim of our study was to evaluate the etiologic classification of stroke in patients with CD using the Causative Classification System (CCS), the ASCOD, and the TOAST classifications in a prospective cohort of patients.

It is caused by the protozoan Trypanosoma cruzi, which was identified in the first decade of the 20th century. Once acute infection resolves, patients can develop chronic disease, which in up to 30 –40% of cases is characterised by cardiomyopathy, arrhythmias, megaviscera, and, more rarely, polyneuropathy and stroke. Even after more than a century, many challenges remain unresolved, since epidemiological control and diagnostic, therapeutic, and prognostic methods must be improved.

Ischemic stroke classification and risk of embolism in patients with Chagas disease
AbstractIschemic stroke (IS) and Chagas disease are strongly related. Nevertheless, little attention has been paid to this association and its natural history. The current guidelines concerning the management and secondary prevention of IS are largely based on the incomplete information or extrapolation of knowledge from other stroke etiologies. We performed a retrospective study which compared stroke etiologies among a cohort of hospitalized patients with IS and Chagas disease. The Instituto de Pesquisa Evandro Chagas/Funda ção Oswaldo Cruz (IPEC/FIOCRUZ) embolic score was also used to identify and evaluate the risk of ...

Developments in the management of Chagas cardiomyopathy.
Authors: Tanowitz HB, Machado FS, Spray DC, Friedman JM, Weiss OS, Lora JN, Nagajyothi J, Moraes DN, Garg NJ, Nunes MC, Ribeiro AL Abstract Over 100 years have elapsed since the discovery of Chagas disease and there is still much to learn regarding pathogenesis and treatment. Although there are antiparasitic drugs available, such as benznidazole and nifurtimox, they are not totally reliable and often toxic. A recently released negative clinical trial with benznidazole in patients with chronic Chagas cardiomyopathy further reinforces the concerns regarding its effectiveness. New drugs and new delivery systems, incl...

Rivaroxaban for treatment of intraventricular thrombus in Chagas disease
We present a case of a 61-year-old man admitted for stroke 5 months after a renal embolism. An intraventricular thrombus was observed, probably the source of the cerebral and renal embolisms. The patient refused warfarin and rivaroxaban was used instead. After 40 days of treatment the thrombus had dissolved, after 20 months of regular use of rivaroxaban no more embolic events were observed. The use of rivaroxaban was effective in preventing embolic events in Chagas disease and intraventricular thrombus. <Learning objective: Warfarin is recommended for stroke prevention in patients with Chagas disease and left ventri...

Chagas disease as a cause of heart failure and ventricular arrhythmias in patients long removed from endemic areas: an emerging problem in Europe
We report two examples of Chagas cardiomyopathy in South American women permanently residing in Italy for more than 20 years, presenting with cardiac manifestations ranging from left ventricular dysfunction and heart failure to isolated ventricular arrhythmias. The present review emphasizes that Chagas disease should be considered as a potential diagnosis in patients from endemic areas presenting with ‘idiopathic’ cardiac manifestations, even when long removed from their country of origin, with potential implications for treatment and control of Chagas disease transmission.
