In 82 patients with acute myocardial infarction, observed haemodynamic changes were compared with the average maximal serum enzyme rise and the infarct size, as calculated from serial determinations of creatine phosphokinase concentration. For this purpose, patients were divided into 3 groups according to their pulmonary artery end-diastolic pressure at the time of admission. There were I9 pati...
Introduction: Hypertension is one of the most important preventable risk factors for cardiovascular disease. This observational study aimed to depict the role of regular blood donation on the systolic and diastolic blood pressure (SBP and DBP, respectively) in hypertensive patients in comparison with normotensive people. Methods: This study was performed as a cross-sectional descriptive study ...
abstract introduction: smoking is an important risk factor of coronary artery disease. nicotine replacement therapy (nrt) for smoking cessation should be considered, especially in coronary patients. methods: twenty-four healthy smokers, smoking an average of 20 cigarettes a day for 15 years and with moderate cigarette dependence (according to the fagershtrum questionnaire score) were randomly ...
background: alveolar hypoxia induces monophasic pulmonary vasoconstriction in vivo, biphasic vasoconstriction in the isolated pulmonary artery, and controversial responses in the isolated perfused lung. pulmonary vascular responses to sustained alveolar hypoxia have not been addressed in the isolated perfused rat lung. in this study, we investigated the effect of sustained hypoxic ventilation o...
Operations in the pleural cavity are connected with circulatory changes in pulmonary circulation and general changes of hemodynamics. These changes are influenced by the position of patient's body on the operation table and by the introduction of artificial pneumothorax. Thoracoscopy is an advanced surgical approach in thoracic surgery, but its hemodynamic effect is still not known. The aim of ...
تغییرات فشار خون و ارتباط آن با شاخصهای تن سنجی و بلوغ در طی روزهداری در دختران 8 تا 13 ساله تهرانی
Background: The present study was designed to evaluate blood pressure changes in Tehranian 8–13 y old fasting girls during Ramadan and determine effective factors in order to observe blood pressure alteration independently. Materials and methods: Totally, 337 female students aged 8-13 years (mean 10±1), were selected by stratified randomized method among volunteer girls intending to fast the w...
background: systolic blood pressure recovery (rsbp) is of prognostic value for predicting the survival and co-morbidity rate in patients with coronary artery disease (cad). this study investigated the association between rsbp and exercise indices after complete cardiac rehabilitation program (cr) in a population-based sample of patients undergoing coronary artery bypass grafting (cabg). methods...
Background and purpose : Respirators (respiratory protective equipments) are widely used, but many of their health impacts, especially cardiovascular effects, have not been determined. The aim of this study was to determine the impact of using respirators on heart rate, systolic and diastolic blood pressure. Materials and methods : This interventional study was undertaken on 40 healthy 2...
Background: Alveolar hypoxia induces monophasic pulmonary vasoconstriction in vivo, biphasic vasoconstriction in the isolated pulmonary artery, and controversial responses in the isolated perfused lung. Pulmonary vascular responses to sustained alveolar hypoxia have not been addressed in the isolated perfused rat lung. In this study, we investigated the effect of sustained hypoxic ventilation o...
