    Mode of Death on Chagas Heart Disease: Comparison with Other Etiologies. A Subanalysis of the REMADHE Prospective Trial
    (2013) AYUB-FERREIRA, Silvia M.; MANGINI, Sandrigo; ISSA, Victor S.; CRUZ, Fatima D.; BACAL, Fernando; GUIMARAES, Guilherme V.; CHIZZOLA, Paulo R.; CONCEICAO-SOUZA, Germano E.; MARCONDES-BRAGA, Fabiana G.; BOCCHI, Edimar A.
    Background: Sudden death has been considered the main cause of death in patients with Chagas heart disease. Nevertheless, this information comes from a period before the introduction of drugs that changed the natural history of heart failure. We sought to study the mode of death of patients with heart failure caused by Chagas heart disease, comparing with non-Chagas cardiomyopathy. Methods and results: We examined the REMADHE trial and grouped patients according to etiology (Chagas vs non-Chagas) and mode of death. The primary end-point was all-cause, heart failure and sudden death mortality; 342 patients were analyzed and 185 (54.1%) died. Death occurred in 56.4% Chagas patients and 53.7% non-Chagas patients. The cumulative incidence of all-cause mortality and heart failure mortality was significantly higher in Chagas patients compared to non-Chagas. There was no difference in the cumulative incidence of sudden death mortality between the two groups. In the Cox regression model, Chagas etiology (HR 2.76; CI 1.34-5.69; p = 0.006), LVEDD (left ventricular end diastolic diameter) (HR 1.07; CI 1.04-1.10; p<0.001), creatinine clearance (HR 0.98; CI 0.97-0.99; p = 0.006) and use of amiodarone (HR 3.05; CI 1.47-6.34; p = 0.003) were independently associated with heart failure mortality. LVEDD (HR 1.04; CI 1.01-1.07; p = 0.005) and use of beta-blocker (HR 0.52; CI 0.34-0.94; p = 0.014) were independently associated with sudden death mortality. Conclusions: In severe Chagas heart disease, progressive heart failure is the most important mode of death. These data challenge the current understanding of Chagas heart disease and may have implications in the selection of treatment choices, considering the mode of death.

    Effects of the exercise training on skeletal muscle oxygen consumption in heart failure patients with reduced ejection fraction
    (2021) GUIMARAES, Guilherme Veiga; RIBEIRO, Fernando; CASTRO, Rafael Ertner; ROQUE, Jean Marcelo; MACHADO, Alexander Douglas Teixeira; ANTUNES-CORREA, Ligia M.; FERREIRA, Silvia Ayub; BOCCHI, Edimar Alcides
    Aims: Skeletal muscle dysfunction is a systemic consequence of heart failure (HF) that correlates with functional capacity. However, the impairment within the skeletal muscle is not well established. We investigated the effect of exercise training on peripheral muscular performance and oxygenation in HF patients. Methods and results: HF patients with ejection fraction <= 40% were randomized 2:1 to exercise training or control for 12 weeks. Muscle tissue oxygen was measured noninvasively by near-infrared spectroscopy (NIPS) during rest and a symptom-limited cardiopulmonary exercise test (CPET) before and after intervention. Measurements included skeletal muscle oxygenated hemoglobin concentration, deoxygenated hemoglobin concentration, total hemoglobin concentration, VO2 peak, VE/VCO2 slope, and heart rate. Muscle sympathetic nerve activity by microneurography, and muscle blood flow by plethysmography were also assessed at rest pre and post 12 weeks. Twenty-four participants (47.5 +/- 7.4 years, 58% men, 75% no ischemic) were allocated to exercise training (ET, n = 16) or control (CG, n = 8). At baseline, no differences between groups were found. Exercise improved VO2 peak, slope VE/VCO2, and heart rate. After the intervention, significant improvements at rest were seen in the ET group in muscle sympathetic nerve activity and muscle blood flow. Concomitantly, a significant decreased in Oxy-Hb (from 29.4 +/- 20.4 to 15.7 +/- 9.0 mu mol, p = 0.01), Deoxi-Hb (from 16.3 +/- 8.2 to 12.2 +/- 6.0 mu mol, p = 0.003) and HbT (from 45.7 +/- 27.6 to 27.7 +/- 13.4 mu mol, p = 0.008) was detected at peak exercise after training. No changes were observed in the control group. Conclusion: Exercise training improves skeletal muscle function and functional capacity in HF patients with reduced ejection fraction. This improvement was associated with increased oxygenation of the peripheral muscles, increased muscle blood flow, and decreased sympathetic nerve activity.

    Impact of Exhaled Breath Acetone in the Prognosis of Patients with Heart Failure with Reduced Ejection Fraction (HFrEF). One Year of Clinical Follow-up
    (2016) MARCONDES-BRAGA, Fabiana G.; BATISTA, Guilherme L.; GUTZ, Ivano G. R.; SALDIVA, Paulo H. N.; MANGINI, Sandrigo; ISSA, Victor S.; AYUB-FERREIRA, Silvia M.; BOCCHI, Edimar A.; PEREIRA, Alexandre Costa; BACAL, Fernando
    Background The identification of new biomarkers of heart failure (HF) could help in its treatment. Previously, our group studied 89 patients with HF and showed that exhaled breath acetone (EBA) is a new noninvasive biomarker of HF diagnosis. However, there is no data about the relevance of EBA as a biomarker of prognosis. Objectives To evaluate whether EBA could give prognostic information in patients with heart failure with reduced ejection fraction (HFrEF). Methods After breath collection and analysis by gas chromatography-mass spectrometry and by spectrophotometry, the 89 patients referred before were followed by one year. Study physicians, blind to the results of cardiac biomarker testing, ascertained vital status of each study participant at 12 months. Results The composite endpoint death and heart transplantation (HT) were observed in 35 patients (39.3%): 29 patients (32.6%) died and 6 (6.7%) were submitted to HT within 12 months after study enrollment. High levels of EBA (>= 3.7 mu g/L, 50th percentile) were associated with a progressively worse prognosis in 12-month follow-up (log-rank = 11.06, p = 0.001). Concentrations of EBA above 3.7 mu g/L increased the risk of death or HT in 3.26 times (HR = 3.26, 95% CI = 1.56-6.80, p = 0.002) within 12 months. In a multivariable cox regression model, the independent predictors of all-cause mortality were systolic blood pressure, respiratory rate and EBA levels. Conclusions High EBA levels could be associated to poor prognosis in HFrEF patients.

    Diagnostic discrepancies in clinical practice An autopsy study in patients with heart failure
    (2017) ISSA, Victor Sarli; DINARDI, Layara Fernanda Lipari; PEREIRA, Thiago Vicente; ALMEIDA, Lyna Kyria Rodrigues de; BARBOSA, Thaisa Silveira; BENVENUTTI, Luiz Alberto; AYUB-FERREIRA, Silvia Moreira; BOCCHI, Edimar Alcides
    Autopsies are the gold standard for diagnostic accuracy; however, no recent study has analyzed autopsies in heart failure (HF). We reviewed 1241 autopsies (January 2000-May 2005) and selected 232 patients with HF. Clinical and autopsy diagnoses were analyzed and discrepancies categorized according to their importance regarding therapy and prognosis. Mean age was 63.3 +/- 15.9 years; 154 (66.4%) patients were male. The causes of death at autopsy were end-stage HF (40.9%), acute myocardial infarction (17.2%), infection (15.9), and pulmonary embolism 36 (15.5). Diagnostic discrepancies occurred in 191 (82.3%) cases; in 56 (24.1%), discrepancies were related to major diagnoses with potential influence on survival or treatment; pulmonary embolism was the cause of death for 24 (42.9%) of these patients. In 35 (15.1%), discrepancies were related to a major diagnosis with equivocal influence on survival or treatment; in 100 (43.1%), discrepancies did not influence survival or treatment. In multivariate analysis, age (OR: 1.03, 95% CI: 1.008-1.052, P=0.007) and presence of diabetes mellitus (OR: 0.359, 95% CI: 0.168-0.767, P=0.008) influenced the occurrence discrepancies. Diagnostic discrepancies with a potential impact on prognosis are frequent in HF. These findings warrant reconsideration in diagnostic and therapeutic practices with HF patients.

    (2021) ISSA, Victor Sarli; AYUB-FERREIRA, Silvia Moreira; SCHROYENS, Matthew; CHIZZOLA, Paulo Roberto; SOARES, Paulo Rogerio; LAGE, Silvia Helena Gelas; BOCCHI, Edimar Alcides
    Aims This study aimed to analyse the clinical presentation and prognosis of patients with Chagas cardiomyopathy and decompensated heart failure (HF), as compared with other aetiologies. Methods and results A prospective cohort of patients admitted with decompensated HF. We included 767 patients (63.9% male), with median age of 58 years [interquartile range 48.2-66.7 years]. Main aetiologies were non-Chagas/non-ischaemic cardiomyopathies in 389 (50.7%) patients, ischaemic disease in 209 (27.2%), and Chagas disease in 169 (22%). Median left ventricular ejection fraction was 26% (interquartile range 22-35%). Patients with Chagas differed from both patients with non-Chagas/non-ischaemic and ischaemic cardiomyopathies for a higher proportion of cardiogenic shock at admission (17.8%, 11.6%, and 11%, respectively, P < 0.001) and had lower blood pressure at admission (systolic blood pressure 90 [80-102.5], 100 [85-110], and 100 [88.2-120] mmHg, P < 0.001) and lower heart rate (heart rate 71 [60-80], 87 [70-102], and 79 [64-96.5] b.p.m., P < 0.001). Further, patients with Chagas had higher serum BNP level (1544 [734-3148], 1061 [465-239], and 927 [369-1455] pg/mL, P < 0.001), higher serum bilirubin (1.4 [0.922.44], 1.2 [0.77-2.19], and 0.84 [0.49-1.45] mg/dL, P < 0.001), larger left ventricular diameter (68 [63-73], 67 [58-74], and 62 [56.8-68.3] mm, respectively, P < 0.001), lower left ventricular ejection fraction (25 [21-30]%, 26 [22-35]%, and 30 [25-38]%, P < 0.001), and a higher proportion of patients with right ventricular function (48.8%, 40.7%, and 25.9%, P < 0.001). Patients with Chagas disease were more likely to receive inotropes than patients with non-Chagas/non-ischaemic and ischaemic cardiomyopathies (77.5%, 67.5%, and 62.5%, respectively, P = 0.007) and also to receive intra-aortic balloon pumping (30.8%, 16.2%, and 10.5%, P < 0.001). Overall, the rates of death or urgent transplant were higher among patients with Chagas than in other aetiologies, a difference that was driven mostly due to increased rate of heart transplant during hospital admission (20.2%, 10.3%, and 8.1%). The prognosis of patients at 180 days after hospital admission was worse for patients with Chagas disease as compared with other aetiologies. In patients with Chagas, age [odds ratio (OR) = 0.934, confidence interval (CI)(95%) 0.901-0.982, P = 0.005], right ventricular dysfunction by echocardiography (OR = 2.68, CI95% 1.055-6.81, P = 0.016), and urea (OR = 1.009, CI95% 1.001-1.018, P = 0.038) were significantly associated with prognosis. Conclusions Patients with Chagas cardiomyopathy and decompensated HF have a distinct clinical presentation and worse prognosis compared with other aetiologies.
