- Prognosis and risk stratification in patients with decompensated heart failure receiving inotropic therapy(2018) GOMES, Clara; TERHOCH, Caique Bueno; AYUB-FERREIRA, Silvia Moreira; CONCEICAO-SOUZA, Germano Emilio; SALEMI, Vera Maria Cury; CHIZZOLA, Paulo Roberto; JR, Mucio Tavares Oliveira; LAGE, Silvia Helena Gelas; FRIOES, Fernando; BOCCHI, Edimar Alcides; ISSA, Victor SarliObjectives The prognostic significance of transient use of inotropes has been sufficiently studied in recent heart failure (HF) populations. We hypothesised that risk stratification in these patients could contribute to patient selection for advanced therapies. Methods We analysed a prospective cohort of adult patients admitted with decompensated HF and ejection fraction (left ventricular ejection fraction (LVEF)) less than 50%. We explored the outcomes of patients requiring inotropic therapy during hospital admission and after discharge. Results The study included 737 patients, (64.0% male), with a median age of 58 years (IQR 48-66 years). Main aetiologies were dilated cardiomyopathy in 273 (37.0%) patients, ischaemic heart disease in 195 (26.5%) patients and Chagas disease in 163 (22.1%) patients. Median LVEF was 26 % (IQR 22%-35%). Inotropes were used in 518 (70.3%) patients. In 431 (83.2%) patients, a single inotrope was administered. Inotropic therapy was associated with higher risk of in-hospital death/urgent heart transplant (OR=10.628, 95% CI 5.055 to 22.344, p<0.001). At 180-day follow-up, of the 431 patients discharged home, 39 (9.0%) died, 21 (4.9%) underwent transplantation and 183 (42.4%) were readmitted. Inotropes were not associated with outcome (death, transplant and rehospitalisation) after discharge. Conclusions Inotropic drugs are still widely used in patients with advanced decompensated HF and are associated with a worse in-hospital prognosis. In contrast with previous results, intermittent use of inotropes during hospitalisation did not determine a worse prognosis at 180-day follow-up. These data may add to prognostic evaluation in patients with advanced HF in centres where mechanical circulatory support is not broadly available.
- Exercise training in heart failure with reduced ejection fraction and permanent atrial fibrillation: A randomized clinical trial(2022) ALVES, Leandro S.; BOCCHI, Edimar Alcides; CHIZZOLA, Paulo Roberto; CASTRO, Rafael Ertner; SALEMI, Vera Maria Cury; MELO, Marcelo Dantas Tavares de; ANDRETA, Camila Rocon de Lima; GUIMARAES, Guilherme VeigaBACKGROUND Heart failure (HF) associated with atrial fibrillation increases patients' physical inactivity, worsening their clinical condition and mortality. Exercise training is safe and has clear benefits in HF. However, little is known about the effects of exercise training on patients with HF with reduced ejection fraction and permanent atrial fibrillation (HFAF). OBJECTIVE The purpose of this study was to test the hypothesis that exercise training improves functional capacity, cardiac function, and quality of life in patients with HFAF. METHODS This randomized clinical trial was conducted at the Heart Institute. Patients with HFAF, left ventricular ejection fraction <= 40%, and resting heart rate (HR) <= 80 beats/min were included in the study. Cardiopulmonary testing, echocardiography, nervous system, and quality of life assessment were performed before and after the 12-week protocol period. RESULTS Twenty-six patients (mean age 58 +/- 1 years) were randomized to exercise training (HFAF-trained group; n = 13) or no training (HFAF-untrained group; n = 13). At baseline, no differences between the groups were found. Exercise improved peak oxygen consumption, slope of ventilation per minute/carbon dioxide production, and quality of life. The HFAF-trained group had significantly decreased resting HR (from 73 +/- 2 to 69 +/- 2 beats/ min; P = .02) and recovery HR (from 148 +/- 11 to 128 +/- 9 beats/min; P = .001). Concomitantly, left ventricular ejection fraction increased (from 31% 61% to 36% +/- 0.9%; P=.01), left atrial dimension decreased (from 52 +/- 1.2 to 47 +/- 1 mm; P = .03), and left ventricular end-systolic volume and left ventricular enddiastolic volume deceased (from 69 +/- 2 to 64 +/- 1.8 mL/m(2) and from 9962.1 to 9162 mL/m(2), respectively; P<.05). No changes were observed in the HFAF-untrained group. CONCLUSION Exercise training can improve exercise capacity, quality of life, and cardiac function in patients with HF with reduced ejection fraction and permanent atrial fibrillation.

C.; MUNHOZ, R. T.; BOCCHI, E. A.; AYUB-FERREIRA, S. M.- Clinical findings and prognosis of patients hospitalized for acute decompensated heart failure: Analysis of the influence of Chagas etiology and ventricular function(2018) TERHOCH, Caique Bueno; MOREIRA, Henry Fukuda; AYUB-FERREIRA, Silvia Moreira; CONCEICAO-SOUZA, Germano Emilio; SALEMI, Vera Maria Cury; CHIZZOLA, Paulo Roberto; OLIVEIRA JR., Mucio Tavares; LAGE, Silvia Helena Gelas; BOCCHI, Edimar Alcides; ISSA, Victor SarliAims Explore the association between clinical findings and prognosis in patients with acute decompensated heart failure (ADHF) and analyze the influence of etiology on clinical presentation and prognosis. Methods and results Prospective cohort of 500 patients admitted with ADHF from Aug/2013-Feb/2016; patients were predominantly male (61.8%), median age was 58 (IQ(25-75%) 47-66 years); etiology was dilated cardiomyopathy in 141 (28.2%), ischemic heart disease in 137 (27.4%), and Chagas heart disease in 113 (22.6%). Patients who died (154 [30.8%]) or underwent heart transplantation (53[10.6%]) were younger (56 years [IQ(25-75%) 45-64 vs 60 years, IQ(25-75%) 4967], P=0.032), more frequently admitted for cardiogenic shock (20.3% vs 6.8%, P<0.001), had longer duration of symptoms (14 days [IQ(25-75%) 4-32.8 vs 7.5 days, IQ(25-75%) 2-31], P=0.004), had signs of congestion (90.8% vs 76.5%, P<0.001) and inadequate perfusion more frequently (45.9% vs 28%, P<0.001), and had lower blood pressure (90 [IQ(25-75%) 80-100 vs 100, IQ(25-75%) 90-120], P<0.001). In a logistic regression model analysis, systolic blood pressure (P<0.001, OR 0.97 [95% CI 10.96-0.98] per mmHg) and jugular distention (P=0.004, OR 1.923 [95% CI 1.232-3.001]) were significant. Chagas patients were more frequently admitted for cardiogenic shock (15%) and syncope/arrhythmia (20.4%). Pulmonary congestion was rare among Chagas patients and blood pressure was lower. The rate of in hospital death or heart transplant was higher among patients with Chagas (50.5%). Conclusions A physical exam may identify patients at higher risk in a contemporaneous population. Our findings support specific therapies targeted at Chagas patients in the setting of ADHF.
conferenceObject Clinical characteristics of patients treating heart failure with and without atrial fibrillation under oral anticoagulant therapy.(2016) CHIZZOLA, P. R. Paulo Roberto; ISSA, V. S.; AYUB-FERREIRA, S. M.; SOUZA, G. E. C.; SALEMI, V. C. M.; ALVES, L. S.; GUIMARAES, G. V.; BOCCHI, E. A.- Worsening of heart failure by coronavirus disease 2019 is associated with high mortality(2021) BOCCHI, Edimar Alcides; LIMA, Ivna Girard Cunha Vieira; BISELLI, Bruno; SALEMI, Vera Maria Cury; FERREIRA, Silvia Moreira Ayub; CHIZZOLA, Paulo Roberto; MUNHOZ, Robinson Tadeu; PESSOA, Ranna Santos; CARDOSO, Francisco Akira Malta; BELLO, Mariana Vieira de Oliveira; HAJJAR, Ludhmila Abrahao; GOMES, Brenno RizerioAims Patients with advanced heart failure (HF) with reduced left ventricular ejection fraction (HFrEF) and concurrent coronavirus disease 2019 (COVID-19) might have a higher risk of severe events. Methods and results We retrospectively studied 16 patients with advanced HFrEF who developed COVID-19 between 1 March and 29 May 2020. Follow-up lasted until 30 September. Ten patients previously hospitalized with decompensated HFrEF were infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during hospitalization. Six patients undergoing ambulatory care at initiation of COVID-19 symptoms were hospitalized because of advanced HFrEF. All patients who experienced worsening of HFrEF due to COVID-19 required higher doses or introduction of additional inotropic drugs or intra-aortic balloon pump in the intensive care unit. The mean intravenous dobutamine dose before SARS-CoV-2 infection in previously hospitalized patients (n = 10) and the median (inter-quartile range) peak intravenous dobutamine dose during SARS-CoV-2 infection in all patients (n = 16) were 2 (0-7) mu g/kg/min and 20 (14-20) (P < 0.001), respectively. During follow-up, 56% underwent heart transplantation (n = 2) or died (n = 7). Four patients died during hospitalization from mixed shock consequent to severe acute respiratory syndrome with inflammatory storm syndrome associated with septic and cardiogenic shock during COVID-19. After COVID-19 recovery, two patients died from mixed septic and cardiogenic shock and one from sustained ventricular tachycardia and cardiogenic shock. Five patients were discharged from hospital to ambulatory care. Four were awaiting heart transplantation. Conclusion Worsening of advanced HF by COVID-19 is associated with high mortality. This report highlights the importance of preventing COVID-19 in patients with advanced HF.
