RESUMEN
OBJECTIVES: To evaluate the prevalence of abnormal ECG findings and their association with imaging results in male Brazilian football players. METHODS: The 'B-Pro Foot ECG' is a multicentre observational study conducted in 82 Brazilian professional clubs. It analysed 6125 players aged 15-35 years (2496 white, 2004 mixed-race and 1625 black individuals) who underwent cardiovascular screening from 2002 to 2023. All ECGs were reviewed by two experienced cardiologists in the athlete's care. Those with abnormal findings underwent further investigations, including a transthoracic echocardiogram (TTE). Cardiac magnetic resonance (CMR) was subsequently performed based on TTE findings or clinical suspicion. RESULTS: In total, 180 (3%) players had abnormal ECGs and 176 (98%) showed normal TTE results. Athletes aged 26-35 years had a higher prevalence of abnormal ECGs than younger athletes (15-25 years). Black players had a higher prevalence of T-wave inversion (TWI) in the inferior leads than white players (2.6% vs 1.4%; p=0.005), as well as in V5 (2.9%) and V6 (2.1%) compared with white (1.2% and 1.0%; p<0.001) and mixed-race (1.5% and 1.2%; p<0.05) players, respectively. TTE parameters were similar across ethnicities. However, four out of 75 players with inferolateral TWI showed abnormal TTEs and CMR findings consistent with cardiomyopathies. CMR also showed cardiomyopathies or myocarditis in four players with inferolateral TWI and normal TTEs. In total, nine (0.1%) athletes were diagnosed with cardiac diseases and were followed for 40±30 months, with no cardiac events documented. CONCLUSION: This study found a 3% prevalence of abnormal ECGs in male Brazilian football players. Inferolateral TWI was associated with cardiac pathologies confirmed by CMR, even in athletes with a normal TTE.

BACKGROUND: Brazil has insufficient cardiac rehabilitation capacity, yet density and regional variation in unmet need is unknown. Moreover, South America has CR guidelines, but whether delivery conforms has not been described. OBJECTIVE: This study aimed to establish: (1) cardiac rehabilitation volumes and density, and (2) the nature of programmes, and (3) compare these by: (a) Brazilian region and (b) to other upper middle-income countries (upper-MICs). METHODS: In this cross-sectional study, a survey was administered to cardiac rehabilitation programmes globally. Cardiac associations were engaged to facilitate programme identification. Density was computed using Global Burden of Disease study ischaemic heart disease incidence estimates. Results were compared to data from the 29 upper-MICs with cardiac rehabilitation (N=249 programmes). RESULTS: Cardiac rehabilitation was available in all Brazilian regions, with 30/75 programmes initiating a survey (40.0% programme response rate). There was only one cardiac rehabilitation spot for every 99 ischaemic heart disease patient. Most programmes were funded by government/hospital sources (n=16, 53.3%), but in 11 programmes (36.7%) patients depended on private health insurance. Guideline-indicated conditions were accepted in ≥70% of programmes. Programmes had a team of 3.8±1.9 staff (versus 5.9±2.8 in other upper-MICs, p<0.05), offering 4.0±1.6/10 core components (versus 6.0±1.5 in other upper-MICs, p<0.01; more tobacco cessation and return-to-work counselling needed in particular) over 44.5 sessions/patient (Q25-75=29-65) vs. 32 sessions/patient (Q25-75=15-40) in other upper-MICs (p<0.01). CONCLUSION: Brazilian cardiac rehabilitation capacity must be augmented, but where available, services are consistent across regions, but differ from other upper-MICs in terms of staff size and core components delivered.

PURPOSE: Cardiac rehabilitation (CR) programs decrease morbidity and mortality rates in patients with coronary artery disease, the leading cause of death in Latin America. This study was carried out to assess the characteristics and current level of CR program implementation in South America. METHODS: We carried out a survey of CR programs that were identified using the directory of the South American Society of Cardiology and through an exhaustive search by the investigators. RESULTS: We identified 160 CR programs in 9 of the 10 countries represented in the South American Society of Cardiology and 116 of those responded to our survey. On the basis of survey results from the responding programs, we estimate that the availability of CR programs in South America is extremely low, approximately 1 CR program for every 2 319 312 inhabitants. These CR programs provided services to a median of 180 patients per year (interquartile range, 60-400) and were most commonly led by cardiologists (84%) and physical therapists (72%). Phases I, II, III, and IV CR were offered in 49%, 91%, 89%, and 56% of the centers, respectively. The most commonly perceived barrier to participation in a CR program was lack of referral from the cardiologist or primary care physician, as reported by 70% of the CR program directors. CONCLUSIONS: The number of CR programs in South America appears to be insufficient for a population with a high and growing burden of cardiovascular disease. In addition, there appears to be a significant need for standardization of CR program components and services in the region.

OBJECTIVE: Patients who have to wait in the hospital for coronary artery bypass surgery (CABG) are exposed to the potential risks of immobilization. This clinical trial was conducted to evaluate the effects of an in-hospital cardiopulmonary rehabilitation program performed before and after CABG on postoperative outcomes. DESIGN: Fifty-six patients who had to wait for CABG in-hospital were randomly assigned to a cardiopulmonary rehabilitation (Rehab; n = 29) or to usual care (Control; n = 27). In the Rehab group, intervention lasted for at least 5 days preoperatively until discharge. The program consisted of phase I cardiac rehabilitation associated with respiratory physical therapy. Outcomes were blindly evaluated. RESULTS: By hospital discharge, Rehab patients presented a shorter time to endotracheal extubation (1054 +/- 376 vs. 1340 +/- 666 min, P = 0.05), a reduction in the incidence of pleural effusion (relative risk [RR] = 0.2; 95% confidence interval [CI]: 0.5-0.8), atelectasis (RR = 0.15; 95% CI: 0.03-0.8), pneumonia (0 vs. 7 cases, [P = 0.004]), and atrial fibrillation or flutter (RR = 0.2; 95% CI: 0.05-0.8). Length of in-hospital stay after surgery was also reduced in the Rehab group (5.9 +/- 1.1 vs. 10.3 +/- 4.6 days [P < 0.001]). CONCLUSION: Pre- and postoperative cardiopulmonary rehabilitation in patients who await CABG in the hospital is superior to standard care and leads to a reduced rate of postoperative complications and shorter hospital stay.

Purpose - To report the result of patients treated with IV methylprednisolone divided into three groups and compare their follow-up during the last 12 years. Methods - Seventy children with active rheumatic carditis (76 episodes) in heart failure Class III and IV (NYHA) were studied. The diagnosis was based on modified Jones' criteria. After rulling out infections and stronglyoidiasis, treatment with IV methylprednisolone bolus was started three times a week until the laboratory tests became negative. Patients were divided into 3 groups, according to the time of hospital admittance: Groups 1,2 and 3, comprising of 40, 18 and 12 children, respectively. Results - Eighteen children in Group 1 (45 per cent) were in their 1st attack: 2 series of pulsetherapy were used in 10 (25 per cent), 3 in 9 (23 per cent) and 4 in 21 (52 per cent). In Group 2, 14 cases (77 per cent) were in their 1st attack: 2 series were used in 7 (39 per cent), 4 in 9 (50 per cent) and 5 in 2 (11 per cent). The echocardiogram showed a flail mitral valve in 12 (66 per cent) of these patients (1 death occurred after mitral valvoplasty). In Group 3,6 patients needed 5 or more series of pulsetherapy and a flail mitral valve was present in 5 (41 per cent). One child underwent mitral valve replacement while still in the active phase, after 8 series of pulsetherapy, and another died. The number of patients who needed 5 or more series was significantly higher in Group 3. Conclusion - There were variations in the presentation and evolution of the cases during these 12 year. The established pulsetherapy protocol continues to be useful to treat severe cases.

PURPOSE: To describe the cardiac findings in children with AIDS, the follow-up with treatment and the correlation between clinical and pathological features. METHODS: We studied prospectively 25 children with clinical-laboratorial diagnosis of AIDS, ages between 3 months and 11 years, even those without cardiac symptoms. We classified the signs of AIDS following that of CDC-Atlanta 1994. Eight children died and it was done necropsy in six with macro and microscopic examinations. RESULTS: Fifteen cases had already complications of AIDS and were classified as C2 and C3, 5 as B2, 3 B1 and 2 as A1. Beside the symptoms related to the disease and infections we found signs of congestive heart failure III and IV (NYHA) in 5 children, pericardial effusion in 5, (one of them had cardiac tamponade). In the electrocardiogram (EKG), 8 children had repolarization abnormalities. In 1st echocardiogram (ECHO) we found some features of dilated myocardiopathy in 8 (6 were asymptomatic) 5 of those had pericardial effusion, one child had huge amount of pericardial liquid and also increased measures of intraventricular septum and posterior wall of left ventricle by ECHO and confirmed by necropsy examination. All cases of diagnosis of myocardiopathy received treatment with captopril and 4 also received furosemide and digoxina. Even under oral treatment three of them had deterioration of heart failure but after combined anti-retroviral drugs they showed better cardiac functions. From the six necropsied cases, two had increased heart weight without myocarditis, one had toxoplasma pancarditis and other one had fibrocalcic vasculopathy. CONCLUSION: We found several assymptomatic cases already with decreased ventricular function. Some worsened of heart failure even under apropriate treatment and showed better cardiac index after combined anti-retroviral drugs.
