RESUMEN

Williams-Beuren syndrome (WBS) is a rare, microdeletion syndrome characterized by facial dysmorphisms, intellectual disability, a friendly personality, cardiovascular and other abnormalities. Cardiovascular defects (CVD) are among the most prevalent characteristics in WBS, being supravalvular aortic stenosis (SVAS) the most frequent, followed by peripheral pulmonary stenosis (PPS). A comprehensive retrospective review of medical records of 127 patients with molecular diagnosis of WBS, in a period of 20 years, was done to evaluate the incidence, the natural history of cardiovascular disease, and the need for surgical intervention, including heart transplantation (HT). A total of 94/127 patients presented with CVD. Of these 94 patients, 50% presented with SVAS and 22.3% needed heart surgery and/or cardiac catheterization including one that required HT due to severe SVAS-related heart failure at 19 years of age. The patient died in the postoperative period due to infectious complications. Cardiovascular problems are the major cause of sudden death in patients with WBS, who have a significantly higher mortality risk associated with surgical interventions. There is a higher risk for anesthesia-related adverse events and for major adverse cardiac events following surgery. End-stage heart failure due to myocardial ischemia has been described in WBS patients and it is important to consider that HT can become their only viable option. To our knowledge, the case mentioned here is the first HT reported in an adolescent with WBS. HT can be a viable therapeutic option in WBS patients with adequate evaluation, planning, and a multidisciplinary team to provide the required perioperative care and follow-up.

RESUMEN

BACKGROUND: Nutritional disorders are common among patients with heart failure (HF) and associated with poor prognosis. Importantly, some populations of patients, like the ones with Chagas disease, are frequently excluded from most analyses. OBJECTIVE: We sought to study the occurrence of undernutrition and cachexia in patients with Chagas disease during episodes of decompensated HF (DHF) as compared to other etiologies, and to investigate the influence of these findings on hospital outcomes. METHODS: We performed a consecutive case series study with patients hospitalized with DHF. Patients underwent the Subjective Global Assessment of nutritional status (SGA), besides anthropometric and laboratorial measures, and were evaluated for the occurrence of cachexia, low muscle mass and strength. We studied the occurrence of death or urgent heart transplantation during hospitalization. RESULTS: Altogether, 131 patients were analyzed and 42 (32.1%) had Chagas disease. Patients with Chagas disease had lower Body Mass Index (BMI) (22.4 kg/m2[19.9-25.3] vs. 23.6 kg/m2 [20.8-27.3], p=0.03), higher frequency of undernutrition (76.2% vs 55.1%, p=0.015) and higher occurrence of death or transplant (83.3% vs. 41.6%, p<0.001). We found that, in patients with Chagas etiology, the occurrence of death or cardiac transplantation were associated with undernutrition (3 [42.9%] patients with hospital discharge vs 29 [82.9%] patients with death or heart transplant, p=0.043). CONCLUSIONS: Taken together, our results indicate that patients with Chagas disease hospitalized with DHF often present with nutritional disorders, especially undernutrition; importantly, this finding was associated with the occurrence of death and heart transplant during hospitalization.


FUNDAMENTO: Problemas nutricionais são comuns em pacientes com insuficiência cardíaca (IC) e estão associados a um prognóstico ruim. É relevante mencionar que algumas populações de pacientes, como os com Doença de Chagas, são normalmente excluídas da maioria das análises. OBJETIVO: Buscamos analisar a ocorrência de desnutrição e caquexia em pacientes com Doença de Chagas durante episódios de IC descompensada (ICD) em comparação a outras etiologias, e investigar a influência desses achados em desfechos hospitalares. MÉTODO: Realizamos um estudo de série de casos consecutivos com pacientes hospitalizados com ICD. Os pacientes foram submetidos à Avaliação Nutricional Subjetiva Global (ASG), além de medidas antropométricas e laboratoriais, e foram avaliados para a ocorrência de caquexia, baixa massa muscular e força. Estudamos a ocorrência de morte e transplante cardíaco de urgência durante a internação. RESULTADOS: Ao todo, 131 pacientes foram analisados e 42 (32,1%) tinham Doença de Chagas. Pacientes com Doença de Chagas apresentavam índice de massa corporal (IMC) menor (22,4 kg/m2 [19,9-25,3] vs. 23,6 kg/m2 [20,8-27,3], p=0,03), maior frequência de desnutrição (76,2% vs 55,1%, p=0,015) e mais ocorrências de morte ou transplante (83,3% vs. 41,6%, p<0,001). Observamos que, dentre os pacientes com etiologia da Doença de Chagas, a ocorrência de morte ou transplante cardíaco esteve associada com desnutrição (3 [42,9%] pacientes com alta hospitalar vs. 29 [82,9%] pacientes que morreram ou receberam transplante cardíaco, P=0,043). CONCLUSÕES: Ao todo, nossos resultados indicam que pacientes com Doença de Chagas internados com ICD costumam apresentar problemas nutricionais, principalmente desnutrição. É importante mencionar que este achado esteve associado à ocorrência de morte e transplante cardíaco durante a internação.

RESUMEN

Cardiovascular diseases (CVD) are the most important cause of morbidity and mortality in the general population. Because the high prevalence of COVID-19 and chronic Chagas disease (CCD) where the latter is endemic, all such diseases will likely be observed in the same patient. While COVID-19 can provoke generalized endotheliitis, which can lead to a cytokine storm and a hyper-coagulable state culminating into in-site and at a distance thrombosis. Therefore, small-vessel coronary artery disease (CAD), cerebrovascular disease, thromboembolism, and arrhythmias are prominent findings in COVID-19. In CCD, small-vessel CAD, cardioembolic stroke, pulmonary embolism, heart failure and arrhythmias are frequently observed as a result of a similar but less intense mechanism. Consequently, the association of CCD and COVID-19 will likely increase the incidence of CVD. Thus, doctors on the frontline should be on the alert for this diagnostic possibility so that the proper treatment can be given without any delay.

RESUMEN

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.

RESUMEN

AIMS: 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 (IQ25-75% 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 [IQ25-75% 45-64 vs 60 years, IQ25-75% 49-67], P = 0.032), more frequently admitted for cardiogenic shock (20.3% vs 6.8%, P<0.001), had longer duration of symptoms (14 days [IQ25-75% 4-32.8 vs 7.5 days, IQ25-75% 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 [IQ25-75% 80-100 vs 100, IQ25-75% 90-120], P<0.001). In a logistic regression model analysis, systolic blood pressure (P<0.001, OR 0.97 [95%CI 0.96-0.98] 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.

RESUMEN

BACKGROUND: The risk of thromboembolic events is increased in patients with heart failure (HF); however, few studies have reported thromboembolic findings in HF patients who have undergone autopsy. METHODS AND RESULTS: We reviewed 1457 autopsies (January 2000/July 2006) and selected 595 patients with HF. We studied the occurrence of thromboembolic events in patients' autopsy reports. Mean age was 61.8±15.9 years; 376 (63.2%) were men and 219 (36.8%) women; left ventricular ejection fraction was 42.1±18.7%. HF etiologies were coronary artery disease in 235 (39.5%) patients, valvular disease in 121 (20.3%), and Chagas' disease in 81 (13.6%). The main cause of death was progressive HF in 253 (42.5%) patients, infections in 112 (18.8%), myocardial infarction in 86 (14.5%), and pulmonary embolism in 81 (13.6%). Altogether, 233 patients (39.2%) suffered 374 thromboembolic events. A thromboembolic event was considered the direct cause of death in 93 (24.9%) patients and related to death in 158 (42.2%). The most frequent thromboembolism was pulmonary embolism in 135 (36.1%) patients; in 81 events (60%), it was considered the cause of death. When we compared clinical characteristics of patients, sex (OR=1.511, CI 95% 1.066-2.143, P=.021) and Chagas disease (OR=2.362, CI 95% 1.424-3.918, P=.001) were independently associated with the occurrence of thromboembolisms. CONCLUSIONS: Thromboembolic events are frequent in patients with heart failure revealed at autopsy, and are frequently associated with the death process. Our findings warrant a high degree of suspicion for these occurrences, especially during the care of more susceptible populations, such as women and Chagas patients.

RESUMEN

Objectives: 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.

RESUMEN

BACKGROUND: Anthracycline (ANT) chemotherapy is associated with cardiotoxicity. Prevention with ß-blockers remains controversial. OBJECTIVES: This prospective, randomized, double-blind, placebo-controlled study sought to evaluate the role of carvedilol in preventing ANT cardiotoxicity. METHODS: The authors randomized 200 patients with HER2-negative breast cancer tumor status and normal left ventricular ejection fraction (LVEF) referred for ANT (240 mg/m2) to receive carvedilol or placebo until chemotherapy completion. The primary endpoint was prevention of a ≥10% reduction in LVEF at 6 months. Secondary outcomes were effects of carvedilol on troponin I, B-type natriuretic peptide, and diastolic dysfunction. RESULTS: Primary endpoint occurred in 14 patients (14.5%) in the carvedilol group and 13 patients (13.5%) in the placebo group (p = 1.0). No differences in changes of LVEF or B-type natriuretic peptide were noted between groups. A significant difference existed between groups in troponin I levels over time, with lower levels in the carvedilol group (p = 0.003). Additionally, a lower incidence of diastolic dysfunction was noted in the carvedilol group (p = 0.039). A nonsignificant trend toward a less-pronounced increase in LV end-diastolic diameter during the follow-up was noted in the carvedilol group (44.1 ± 3.64 mm to 45.2 ± 3.2 mm vs. 44.9 ± 3.6 mm to 46.4 ± 4.0 mm; p = 0.057). CONCLUSIONS: In this largest clinical trial of ß-blockers for prevention of cardiotoxicity under contemporary ANT dosage, the authors noted a 13.5% to 14.5% incidence of cardiotoxicity. In this scenario, carvedilol had no impact on the incidence of early onset of LVEF reduction. However, the use of carvedilol resulted in a significant reduction in troponin levels and diastolic dysfunction.

RESUMEN

Trypanosoma cruzi (T. cruzi) infection is endemic in Latin America and is becoming a worldwide health burden. It may lead to heterogeneous phenotypes. Early diagnosis of T. cruzi infection is crucial. Several biomarkers have been reported in Chagas heart disease (ChHD), but most are nonspecific for T. cruzi infection. Prognosis of ChHD patients is worse compared with other etiologies, with sudden cardiac death as an important mode of death. Most ChHD patients display diffuse myocarditis with fibrosis and hypertrophy. The remodeling process seems to be associated with etiopathogenic mechanisms and neurohormonal activation. Pharmacological treatment and antiarrhythmic therapy for ChHD is mostly based on results for other etiologies. Heart transplantation is an established, valuable therapeutic option in refractory ChHD. Implantable cardioverter-defibrillators are indicated for prevention of secondary sudden cardiac death. Specific etiological treatments should be revisited and reserved for select patients. Understanding and management of ChHD need improvement, including development of randomized trials.

RESUMEN

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 ±â€Š15.9 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.

RESUMEN

BACKGROUND: Few studies evaluated systemic arterial embolism after beginning of symptoms of infective endocarditis in a large series of patients. METHODS: We studied 629 patients with left-sided infective endocarditis, aged 37.9+/-17.3 years, 396(63%) men and 233(37%) women. Endocarditis occurred on native valves in 405(64.4%) patients and on prosthetic heart valves in 224(35.6%). Infecting microorganisms were streptococci in 297(47.3%) patients, Staphylococcus aureus in 77(12.3%), Staphylococcus epidermidis in 56(8.9%), enterococci in 51(8.1%), Gram-negative bacteria in 33(5.2%), fungi in 9(1.4%) and other microorganisms in 27(4.2%). In 79(12.6%) patients blood cultures were negative. RESULTS: 146 embolic events occurred in 133(21.1%) out of 629 patients; in 63(47.4%) of them emboli affected the central nervous system, in 57(42.9%) affected peripheral organs and in 13(9.7%) affected both the central nervous system and peripheral organs. Embolism occurred between beginning of symptoms of endocarditis and antimicrobial therapy in 56(42.1%) patients and on the day therapy started in 18(13.5%); 109(81.9%) embolic events occurred up to the 15th day of antimicrobial therapy. Embolic risk was higher in S. aureus endocarditis (relative risk 2.97); in patients with a mitral (relative risk 2.4) or aortic (relative risk 3.3) prosthetic valve and vegetations on echocardiography. Embolic risk was lower in patients with a longer duration of symptoms. The death risk doubled in patients with embolism (relative risk 2.01). CONCLUSIONS: Embolic events were more frequently early events after beginning of symptoms of infective endocarditis. Embolic risk was higher in S. aureus endocarditis and in patients with prosthetic heart valves and vegetations on echocardiography.

RESUMEN

BACKGROUND: Nutritionally variant streptococci (NVS) are Gram-positive cocci characterized by their dependence on pyridoxal or cysteine supplementation for growth in standard blood culture media. They are responsible for severe infections in immunocompetent and immunosuppressed hosts, including infective endocarditis (IE). NVS have been divided into two different genera, Granulicatella and Abiotrophia. METHODS: We report four cases of IE caused by Granulicatella species, including clinical presentation, echocardiographic characteristics, treatments received, and outcomes. We also performed a literature search for previously reported cases of IE caused by Granulicatella species to better characterize this condition. RESULTS: A total of 29 cases of Granulicatella endocarditis were analyzed, including the four newly reported cases. The aortic (44%) and mitral (38%) valves were those most commonly affected. Multivalvular involvement was observed in 13% of cases. The mean vegetation length was 16mm. Complications were frequent, including heart failure (30%), embolism (30%), and perivalvular abscess (11%). The most frequent antibiotic regimen (85%) was penicillin or one of its derivatives plus gentamicin. The mortality rate was 17%. CONCLUSIONS: Endocarditis due to Granulicatella species is a rare and severe condition. Complications are frequent despite the use of appropriate antibiotic regimens.

RESUMEN

BACKGROUND: Polypharmacy is a significant economic burden. OBJECTIVE: We tested whether using reverse auction (RA) as compared with commercial pharmacy (CP) to purchase medicine results in lower pharmaceutical costs for heart failure (HF) and heart transplantation (HT) outpatients. METHODS: We compared the costs via RA versus CP in 808 HF and 147 HT patients followed from 2009 through 2011, and evaluated the influence of clinical and demographic variables on cost. RESULTS: The monthly cost per patient for HF drugs acquired via RA was $10.15 (IQ 3.51-40.22) versus $161.76 (IQ 86.05­340.15) via CP; for HT, those costs were $393.08 (IQ 124.74-774.76) and $1,207.70 (IQ 604.48-2,499.97), respectively. CONCLUSION: RA may reduce the cost of prescription drugs for HF and HT, potentially making HF treatment more accessible. Clinical characteristics can influence the cost and benefits of RA. RA may be a new health policy strategy to reduce costs of prescribed medications for HF and HT patients, reducing the economic burden of treatment.

RESUMEN

BACKGROUND: Hypertension is the most prevalent comorbidity after heart transplantation (HT). Exercise training (ET) is widely recommended as a key non-pharmacologic intervention for the prevention and management of hypertension, but its effects on ambulatory blood pressure (ABP) and some mechanisms involved in the pathophysiology of hypertension have not been studied in this population. The primary purpose of this study was to investigate the effects of ET on ABP and arterial stiffness of HT recipients. METHODS: 40 HT patients, randomized to ET (n = 31) or a control group (n = 9) underwent a maximal graded exercise test, 24-hour ABP monitoring, and carotid-femoral pulse wave velocity (PWV) assessment before the intervention and at a 12-week follow-up assessment. The ET program was performed thrice-weekly and consisted primarily of endurance exercise (40 minutes) at ~70% of maximum oxygen uptake (Vo2MAX). RESULTS: The ET group had reduced 24-hour (4.0 ± 1.4 mm Hg, p < 0.01) and daytime (4.8 ± 1.6 mm Hg, p < 0.01) systolic ABP, and 24-hour (7.0 ± 1.4 mm Hg, p < 0.001) daytime (7.5 ± 1.6 mm Hg, p < 0.001) and nighttime (5.9 ± 1.5 mm Hg, p < 0.001) diastolic ABP after the intervention. The ET group also had improved Vo2MAX (9.7% ± 2.6%, p < 0.001) after the intervention. However, PWV did not change after ET. No variable was changed in the control group after the intervention. CONCLUSIONS: The 12-week ET program was effective for reducing ABP but not PWV in heart transplant recipients. This result suggests that endurance ET may be a tool to counteract hypertension in this high-risk population.
