OBJETIVO: Avaliar o perfil lipídico de indivíduos com sobrepeso e obesidade submetidos à avaliação cardiológica e que não mostraram evidências de cardiopatia. MÉTODOS: Amostra com 684 indivíduos, 389 (56,9%) mulheres e 295 (43,1%) homens, com idade de 14 a 74 (média 40,6) anos, sem evidências de cardiopatia após avaliação clínica e análise do eletrocardiograma, radiografia do tórax, teste ergométrico em esteira e ecocardiograma bidimensional com Doppler. Foi estudado o perfil sérico de lípides e glicose quanto ao sexo e faixas do índice de massa corpórea (IMC) - eutróficos até 24,9 Kg/m², sobrepeso 25-29,9 Kg/m² e obesos > 30 Kg/m². RESULTADOS: Apresentaram diferença estatisticamente significativa entre os sexos (médias): glicose (mg/dL) de mulheres 90,21±23,13 e homens 95,28±28,64 (p<0.001); triglicérides (mg/dL) de mulheres 97,27±55,24 e homens 141,47±57,06 (p<0,001) e HDL-C (mg/dL) de mulheres 52,63±13,92 e homens 43±10,88 (p<0,001). O IMC médio das mulheres foi 26,15 e dos homens 26,33 (p=ns). Na análise por faixas de IMC houve diferença significativa entre os sexos (p=0,037). Na faixa de sobrepeso e obesidade, apenas as médias de triglicérides das mulheres mostraram diferença estatisticamente significativa: mulheres com sobrepeso 102,25±60,68 mg/dL e obesas 121,64±63,57 mg/dL (p=0,034). CONCLUSÃO: Mulheres sem cardiopatia apresentaram níveis séricos de glicose, triglicérides e HDL-colesterol inferiores aos homens. Em ambos os sexos, as médias são menores na comparação entre eutróficos e com excesso de peso, e apenas as médias dos triglicérides das mulheres com sobrepeso e obesidade apresentou diferença significativamente estatística.

OBJECTIVE: To assess the lipidic profile of overweight and obese individuals submitted to cardiologic assessment and who did not show evidences of cardiopathy. METHODS: Sample with 684 individuals, 389 (56.9%) women and 295 (43.1%) men, with age ranging from 14 to 74 (average of 40.6) years old, without evidences of cardiopathy after clinical assessment and analysis of electrocardiogram, thorax radiography, ergometric test on treadmill and two-dimensional Doppler echocardiogram. The serum profile of lipids and glucose regarding sex and ranges of body mass index (BMI) - eutrophic up to 24.9 Kg/m², overweight 25-29.9 Kg/m² and obese > 30 Kg/m², was studied. RESULTS: The following means showed a significant statistic difference between the sexes: glucose (mg/dL) in women 90.21±23.13 and men 95.28±28.64 (p<0.001); triglycerides (mg/dL) in women 97.27±55.24 and men 141.47±57.06 (p<0.001) and HDL-C (mg/dL) in women 52.63±13.92 and men 43±10.88 (p<0.001). The average BMI in women was 26.15 and in men 26.33 (p=ns). In the analysis through BMI ranges there was a significant difference between the sexes (p=0.037). In the categories of overweight and obesity, only the means of triglycerides in women showed a significant statistic difference: overweight women with 102.25±60.68 mg/dL and obese 121.64±63.57 mg/dL (p=0.034). CONCLUSION: Women without cardiopathy showed serum levels of glucose, triglycerides and HDL-cholesterol lower than men's. In both sexes, the means are lower in the comparison with eutrophic and overweight, and only the triglycerides average of women with overweight and obesity showed significant statistic difference.

OBJETIVO: Avaliar os achados ecocardiográficos em pacientes com suspeita diagnóstica de endocardite infecciosa. MÉTODOS: Foram submetidos à investigação ecocardiográfica transtorácica e transesofágica 262 pacientes com suspeita diagnóstica de endocardite infecciosa. Analisadas imagens de vegetações, abscessos valvares e insuficiência periprotética aguda e avaliada a correlação com dados clínicos, laboratoriais, categoria diagnóstica e a evolução hospitalar. RESULTADOS: O diagnóstico de endocardite foi categorizado como definido em 127 (47,8%) episódios, possível em 81 (30,4%) e rejeitado em 58 (21,8%). Nos pacientes com o diagnóstico definido, foram identificadas 135 imagens de vegetações, 37 de abscesso e 6 de insuficiência periprotética. Vegetações foram mais freqüentes em pacientes com endocardite por estreptococos do grupo viridans e enterococos (p=0,02) e com duração dos sintomas < 10 dias (p= 0,001); abscesso mais freqüente em pacientes com duração dos sintomas < 10 dias (p= 0,001) e insuficiência periprotética associada à maior necessidade de tratamento cirúrgico (p=0,001). Nos pacientes com o diagnóstico possível de endocardite, foram identificadas 8 imagens ecocardiográficas consideradas compatíveis com vegetações e, nos pacientes com diagnóstico de endocardite rejeitado, não foram demonstradas vegetações, abscessos valvares e insuficiência periprotética. CONCLUSÃO: Nossos achados ecocardiográficos variaram de acordo com a categoria diagnóstica. A contribuição tanto para o diagnóstico quanto para a avaliação prognóstica deve levar em consideração a probabilidade pré-teste do diagnóstico de endocardite infecciosa.

OBJECTIVE: To assess the echocardiographic findings in patients with suspected infective endocarditis. METHODS: Two hundred sixty-two patients with suspected infective endocarditis underwent transthoracic and transesophageal echocardiographic investigation. Images of vegetations, valvular abscesses, and acute periprosthetic insufficiency were analyzed, and the correlation with clinical and laboratory data, diagnostic category, and hospital evolution was assessed. RESULTS: The diagnosis of endocarditis was categorized as defined in 127 (47.8%) episodes, possible in 81 (30.4%), and rejected in 58 (21.8%). In patients with the defined diagnosis, the following images were identified: 135 vegetations, 37 abscesses, and 6 periprosthetic insufficiencies. Vegetations were more frequent in patients with endocarditis due to streptococci of the viridans group and enterococci (P=0.02), and with symptom duration < 10 days (P=0.001). Abscesses were more frequent in patients with symptom duration < 10 days (P=0.001). Periprosthetic insufficiency was associated with a greater need for surgical treatment (P=0.001). In patients with the possible diagnosis of endocarditis, 8 echocardiographic images considered compatible with vegetations were identified. In patients whose diagnosis of endocarditis was rejected, no vegetations, valvular abscesses, or periprosthetic insufficiencies were demonstrated. CONCLUSION: Our echocardiographic findings varied according to the diagnostic category. The contribution to both the diagnosis and prognostic evaluation should consider the pretest probability of the diagnosis of infective endocarditis.

OBJECTIVE: To evaluate the relationship between 24-hour ambulatory arterial blood pressure monitoring and the prognosis of patients with advanced congestive heart failure. METHODS: We studied 38 patients with NYHA functional class IV congestive heart failure, and analyzed left ventricular ejection fraction, diastolic diameter, and ambulatory blood pressure monitoring data. RESULTS: Twelve deaths occurred. Left ventricular ejection fraction (35.2±7.3%) and diastolic diameter (72.2±7.8mm) were not correlated with the survival. The mean 24-hour (SBP24), waking (SBPw), and sleeping (SBPs) systolic pressures of the living patients were higher than those of the deceased patients and were significant for predicting survival. Patients with mean SBP24, SBPv, and SBPs > or = 105mmHg had longer survival (p=0.002, p=0.01 and p=0.0007, respectively). Patients with diastolic blood pressure sleep decrements (dip) and patients with mean blood pressure dip <=6mmHg had longer survival (p=0.04 and p=0.01, respectively). In the multivariate analysis, SBPs was the only variable with an odds ratio of 7.61 (CI: 1.56; 3704) (p=0.01). Patients with mean SBP<105mmHg were 7.6 times more likely to die than those with SBP > or = 105 mmHg CONCLUSION: Ambulatory blood pressure monitoring appears to be a useful method for evaluating patients with congestive heart failure.
