Estudo multicêntrico de avaliação perioperatória para operações não cardíacas (EMAPO)
INTRODUCTION: The accuracy of perioperative evaluation methods available is better than chance, but their performance is not ideal. OBJECTIVES: To compare a new evaluation method (EMAPO) to the American College of Physicians method for determining the risk of cardiovascular complications in noncardiac surgeries and to look for new influencing variables. METHODS: Evaluations through EMAPO and the American College of Physicians method were employed for 700 patients. Cardiac events and deaths were recorded, the risk variables related to the occurrence of complications were verified, and the models were compared by analyzing the areas under the receiver operating characteristic curves. RESULTS: Mortality rate was 3.4%, and the incidence of cardiovascular complications was 5.3%. Renal failure (P = 0.01), major surgery (P = 0.004), and emergency surgery (P = 0.003) were independently related to the occurrence of cardiovascular complications. The two methods produced similar results. CONCLUSION: EMAPO is as good as the American College of Physicians method in determining the risk of cardiovascular complications in noncardiac surgeries. New variables related to surgical risk were identified.INTRODUÇÃO: A precisão dos métodos de avaliação perioperatória disponíveis é melhor que o acaso, porém está longe do ideal. OBJETIVOS: Comparar um novo método de avaliação perioperatória (EMAPO) ao método do American College of Physicians para determinar o risco cardíaco em cirurgias não cardíacas e buscar novas variáveis envolvidas na determinação deste risco. MÉTODOS: O EMAPO e o método do American College of Physicians foram aplicados em 700 pacientes. A ocorrência de eventos cardíacos e de mortes foi documentada, a relação entre as variáveis de risco e as complicações foi estabelecida e os métodos foram comparados analisando as áreas sob a curva ROC. RESULTADOS: A mortalidade foi 3.4% e a incidência de complicações cardiovasculares 5.3%. A presença de insuficiência renal (p=0.01), cirurgia de grande porte (p=0.004) e cirurgia de emergência (p=0.003) se correlacionaram com a ocorrência de complicações cardiovasculares na análise multivariada. Não houve diferença entre os dois métodos. CONCLUSÕES: O EMAPO é tão eficaz quanto o método do American College of Physicians para determinar o risco de complicações cardiovasculares em cirurgias não cardíacas. Novas variáveis relacionadas com o risco perioperatório foram encontradas
Multicenter study of perioperative evaluation for noncardiac surgeries in Brazil (EMAPO)
Impact of cardiology referral: clinical outcomes and factors associated with physicians' adherence to recommendations
OBJECTIVES: Cardiology referral is common for patients admitted for non-cardiac diseases. Recommendations from cardiologists may involve complex and aggressive treatments that could be ignored or denied by other physicians. The purpose of this study was to compare the outcomes of patients who were given recommendations during cardiology referrals and to examine the clinical outcomes of patients who did not follow the recommendations. METHODS: We enrolled 589 consecutive patients who received in-hospital cardiology consultations. Data on recommendations, implementation of suggestions and outcomes were collected. RESULTS: Regarding adherence of the referring service to the recommendations, 77% of patients were classified in the adherence group and 23% were classified in the non-adherence group. Membership in the non-adherence group (

Hyperlipidemia related to the use of HIV-protease inhibitors: natural history and results of treatment with fenofibrate
Hyperlipidemia has been frequently recorded as a side effect of treating HIV patients with protease inhibitors (PI). This study was initiated to analyze the modifications on blood lipids in HIV-patients receiving PI and the safety and efficacy of the treatment with fenofibrate. Total (TC) and HDL-cholesterol, triglycerides (TG), and CD4+ T-cell counts were measured in 30 HAART-naive patients (Group I) before and after PI introduction. In a second phase of the study, the effects of fenofibrate on lipids, CPK, CD4+, and viral load were determined in 13 patients (Group II) with elevated TC or TG. In Group I, 60% of the patients showed TC or TG elevations. Average increments of 31% and 146% in TC and TG respectively (p<0.0006 and p<0.0001) were observed. In Group II, fenofibrate treatment was associated with decrements of 6.6% (TC) and 45.7% (TG) (p=0.07 and 0.0002) and no modifications on CPK, CD4+, and viral load. In conclusion, hyperlipidemia is common during the treatment of HIV with protease inhibitors, and fenofibrate appears to be an effective and safe choice for its treatment
