13. Validation of the angina questionnaire of the oms on the short version using as gold standard the exercise treadmill test and the pharmacological stress echocardiography / Validação do questionário de angina da OMS na sua versão curta utilizando como padrão ouro o teste de esforço e o ecocardiograma sob estresse farmacológico
OBJECTIVE: To assess the validity of the short version of the WHO/Rose angina questionnaire in Portuguese, applied to adults aged 40-74 years, living at Butantã, reference area of the Hospital Universitário - Universidade de São Paulo, in Brazil using exercise treadmill test and pharmacological stress echocardiography as gold standard. To analyze if the a

14. Blockade of the action of nitric oxide in human septic shock increases systemic vascular resistance and has detrimental effects on pulmonary function after a short infusion of methylene blue
To investigate the role of nitric oxide in human sepsis, ten patients with severe septic shock requiring vasoactive drug therapy and mechanical ventilation were enrolled in a prospective, open, non-randomized clinical trial to study the acute effects of methylene blue, an inhibitor of guanylate cyclase. Hemodynamic and metabolic variables were measured befor

15. Escore eletrocardiográfico para avaliação de isquemia miocárdica: aplicação em testes ergométricos sequenciais para avaliação do fenômeno do aquecimento / Electrocardiographic score for myocardial ischemia evaluation: application in sequential exercise tests for warm-up phenomenon evaluation
The time to 1.0mm ST-segment depression (T-1.0mm), adopted to document the warm-up phenomenon, an expression of the ischemic preconditioning (IPC), during sequential exercise tests is considered reliable and reproductible, although with several limitations. The main goal of this study was to apply an electrocardiographic ischemic myocardium score to sequenti

16. Remodeling of dystrophin-glycoprotein complex, intercalated disk proteins, and contractile proteins in the hearts of mice subjected to sepsis induced by cecal ligation and puncture. / Remodelamento do complexo de glicoproteínas associadas à distrofina, do disco intercalar e das proteínas contráteis no coração de camundongos submetidos à sépsis induzida por ligação e perfuração do ceco
Sepsis and septic shock represent a complex syndrome of systemic inflammatory response, with multiple physiological and immunological abnormalities, commonly caused by bacterial infection. The most important consequence of the response is the involvement of many organs and tissues. Cardiac dysfunction, caused by impairment in myocardial contractility, has be

17. Validation of the nursing diagnosis Deficient Knowledge related to coronary artery disease and coronary artery bypass grafting / Validação do diagnóstico de enfermagem conhecimento deficiente em relação à doença arterial coronariana e à revascularização do miocárdio
The main goals of this research were the content and clinical validation of the defining characteristics of the nursing diagnosis Deficient knowledge in relation to coronary artery disease and coronary artery bypass grafting. The Diagnostic Content Validation Model and the patient-focused Clinical Diagnostic Validity Model proposed by Fehring (1987) were use

18. Morphine pharmacokinetic-pharmacodynamic modeling administered by patient controlled analgesia (PCA) pump in the postoperative period of myocardial revascularization surgery / Modelagem farmacocinética-farmacodinâmica da morfina administrada através de bomba controlada pelo paciente no pós-operatório de revascularização do miocárdio
Introduction: Morphine administration using patient controlled analgesia (PCA) for treatment of post surgical and traumatic pain has been a current practice in many hospitals. However, large or repeated doses of this opioid are associated to dose dependent adverse events, including, respiratory depression. Considering patients submitted to thoracic surgery,

19. The effect of repaglinide on ischemic preconditioning / Efeito da repaglinida sobre o pré-condicionamento isquêmico
Background: The increase of tolerance to myocardial ischemia observed during the second of two sequential exercise tests, the warm-up phenomenon, has been proposed as a clinical model of ischemic preconditioning. Blockers of K-ATP channels, such as the Sulfonylurea drugs, can induce loss of ischemic preconditioning, what could be involved in an increase of c

20. Cardiopulmonary bypass alters the pharmacokinetics of propranolol in patients undergoing cardiac surgery
The pharmacokinetics of propranolol may be altered by hypothermic cardiopulmonary bypass (CPB), resulting in unpredictable postoperative hemodynamic responses to usual doses. The objective of the present study was to investigate the pharmacokinetics of propranolol in patients undergoing coronary artery bypass grafting (CABG) by CPB under moderate hypothermia

21. Inotropic effect of Citrus sinensis (L.) Osbeck leaf extracts on the guinea pig atrium
The objective of the present investigation was to determine the contractile effect of crude and acetone leaf extracts of Citrus sinensis (L.) Osb. on mammalian myocardium. Crude leaf extracts have been used in folk medicine to treat neurological disorders. Some flavonoids isolated from this plant presented a positive inotropic effect on myocardium. This moti

23. Serum determination of creatinephosphokinase-isoenzyme MB (CK-MB) enzyme and of troponin I (cTnI) in electrocardiographic normal dogs and in those with ST deviation (elevation or depression) by a chemiluminescent immunometric assay / Dosagem sérica da enzima creatinafosfoquinase-isoenzima MB (CK-MB) e de troponina I (cTnI) de cães eletrocardiograficamente normais e naqueles com desníveis (infra e supra) do segmento ST, utilizando ensaio imunométrico por quimioluminescência
Although very often in men, hypoxic and ischemic heart diseases are poorly documented in dogs. There are few reports of acute myocardial infarction (AMI) in this species. However, some electrocardiographic findings may suggest myocardium hypoxia/ischemia, like ST segment elevation or depression. In order to investigate myocardial cells injury in poor perfusi

24. Avaliação de parametros cardiovasculares em pacientes portadores de doença arterial coronariana, submetidos a anestesia local
The purpose of this study was to evaluate the changes of cardiovascular parameters in 15 volunteers with acute CAD (instable angina and previous myocardial infarction) during dental treatment under local anesthesia with epinephrine and felypressine. Ambulatory monitoring (BPAM) and ECG were utilized to evaluate systolic (SBP) and diastolic (OBP) blood pressu
