Substituição valvar isolada com próteses metálicas St. Jude Medical em posição aórtica ou mitral: seguimento de médio prazo

FUNDAMENTO: Em nosso meio as próteses valvares biológicas predominam, considerando-se as dificuldades relacionadas à anticoagulação, mesmo em pacientes jovens, a despeito da necessidade de repetidas operações devido à degeneração das próteses biológicas. OBJETIVO: Apresentar a evolução em médio prazo de pacientes submetidos à substituição da valva mitral ou aórtica por prótese valvar mecânica St. Jude. MÉTODOS: Foi analisada retrospectivamente a evolução dos pacientes operados entre janeiro de 1995 e dezembro de 2003 e seguidos até dezembro de 2006. RESULTADOS: Cento e sessenta e oito pacientes receberam prótese valvar mitral e 117, aórtica. A idade média de ambos os grupos foi de 45 anos. Entre os mitrais, 75% tinham até 55 anos e 65% eram mulheres. Entre os aórticos, 66% tinham até 55 anos e 69% eram homens. Considerando-se apenas mortes relacionadas às próteses valvares, a sobrevida foi de 85,6% para os mitrais e de 88,7% para os aórticos (p=0,698). Entre os mitrais, 97% estavam livres de reoperação, e entre os aórticos 99% (p=0,335). Quanto aos eventos tromboembólicos, a porcentagem de pacientes livres foi de 82% entre os mitrais e de 98% entre os aórticos (p=0,049), e para os eventos hemorrágicos foi de 71% e 86% respectivamente (0,579). Quanto à ocorrência de endocardite, 98 % entre os mitrais e 99% entre os aórticos estavam livres ao final de 10 anos (p=0,534). CONCLUSÃO: Nossa experiência com próteses metálicas St. Jude em uma população predominantemente jovem confirma o bom desempenho desta prótese, em acordo com outras experiências publicadas.

Free Medical Information Doctor = Publisher

Today, doctors can be publishers – computer technology and the internet make it possible, and book projects are tempting in terms of money. A doctor who publishes his own textbooks can earn many times what he would be paid in royalties by a publishing house. More important than this, however, is the fact that a doctor who writes and publishes wants his texts to be read by as many colleagues, students and patients as possible. The best way to achieve this is through free parallel publication of these texts on the internet

Clinical Differences between Subtypes of Atrial Fibrillation and Flutter: Cross-Sectional Registry of 407 Patients

Introduction:Atrial fibrillation and atrial flutter account for one third of hospitalizations due to arrhythmias, determining great social and economic impacts. In Brazil, data on hospital care of these patients is scarce.Objective:To investigate the arrhythmia subtype of atrial fibrillation and flutter patients in the emergency setting and compare the clinical profile, thromboembolic risk and anticoagulants use.Methods:Cross-sectional retrospective study, with data collection from medical records of every patient treated for atrial fibrillation and flutter in the emergency department of Instituto de Cardiologia do Rio Grande do Sul during the first trimester of 2012.Results:We included 407 patients (356 had atrial fibrillation and 51 had flutter). Patients with paroxysmal atrial fibrillation were in average 5 years younger than those with persistent atrial fibrillation. Compared to paroxysmal atrial fibrillation patients, those with persistent atrial fibrillation and flutter had larger atrial diameter (48.6 ± 7.2 vs. 47.2 ± 6.2 vs. 42.3 ± 6.4; p < 0.01) and lower left ventricular ejection fraction (66.8 ± 11 vs. 53.9 ± 17 vs. 57.4 ± 16; p < 0.01). The prevalence of stroke and heart failure was higher in persistent atrial fibrillation and flutter patients. Those with paroxysmal atrial fibrillation and flutter had higher prevalence of CHADS2 score of zero when compared to those with persistent atrial fibrillation (27.8% vs. 18% vs. 4.9%; p < 0.01). The prevalence of anticoagulation in patients with CHA2DS2-Vasc &#8804; 2 was 40%.Conclusions:The population in our registry was similar in its comorbidities and demographic profile to those of North American and European registries. Despite the high thromboembolic risk, the use of anticoagulants was low, revealing difficulties for incorporating guideline recommendations. Public health strategies should be adopted in order to improve these rates.

Changes in Medical Management after Coronary CT Angiography

AbstractIntroduction:Coronary computed tomography angiography (CCTA) allows for non-invasive coronary artery disease (CAD) phenotyping. There are still some uncertainties regarding the impact this knowledge has on the clinical care of patients.Objective:To determine whether CAD phenotyping by CCTA influences clinical decision making by the prescription of cardiovascular drugs and their impact on non-LDL cholesterol (NLDLC) levels.Methods:We analysed consecutive patients from 2008 to 2011 submitted to CCTA without previous diagnosis of CAD that had two serial measures of NLDLC, one up to 3 months before CCTA and the second from 3 to 6 months after.Results:A total of 97 patients were included, of which 69% were men, mean age 64 ± 12 years. CCTA revealed that 18 (18%) patients had no CAD, 38 (39%) had non-obstructive (< 50%) lesions and 41 (42%) had at least one obstructive &#8805; 50% lesion. NLDLC was similar at baseline between the grups (138 ± 52 mg/dL vs. 135 ± 42 mg/dL vs. 131 ± 44 mg/dL, respectively, p = 0.32). We found significative reduction in NLDLC among patients with obstrctive lesions (-18%, p = 0.001). We also found a positive relationship between clinical treatment intensification with aspirin and cholesterol reducing drugs and the severity of CAD.Conclusion:Our data suggest that CCTA results were used for cardiovascular clinical treatment titration, with especial intensification seen in patients with obstructive &#8805;50% CAD.
