Background: Rose questionnaire is a standard mean for diagnosing angina pectoris in epidemiological study. The present study was done to determine the prevalence of angina pectoris according to Rose questionnaire for chest pain, and to investigate the association of angina with several coronary hearh disease risk factors in Tehran urban population (district-13) during 1999 to 2000. Methods: 60...

were studied in 26 patients with coronary artery disease. Angina was induced by rapid atrial pacing and measurements were made at rest and during angina in the immediate post-pacing period. No changes occurred in heart rate (71 ± 3 to 73 ± 3 beats/min, NS) or right ventricular (RV) end-diastolic pressure (10 ± I to 11 ± 1 mm Hg, NS), while significant increases occurred in LV end-diastolic pres...

SUMMARY The sequence of events characterizing the onset and course of exercise-induced angina pectoris was studied in 10 patients with ischemic heart disease during cardiac catheterization. Exercise produced a precipitous rise in left ventricular end-diastolic pressure prior to the onset of angina and electrocardiographic ischemia. A corresponding abnormal increase in pulmonary artery pressure ...

conclusions graft failure is more likely to occur in patients with higher serum creatinine levels. results there was a positive association between the serum creatinine level and graft failure (hr = 5.13, p < 0.001). a one unit increase in the serum creatinine level suggests an increased risk of graft failure of up to 5.13 times. the serum creatinine level significantly decreased over time (95%...

patients and methods in this multicenter cross sectional study, 397 consecutive patients on hemodialysis were evaluated by face-to-face interviews. rls was diagnosed using the international rls study group (irlss) criteria. in addition, three validated sleep disorder questionnaires (insomnia severity index, epworth sleepiness scale and pittsburgh sleep quality index) were completed by the patie...

this study was undertaken to define the prevalence of the upper gastrointestinal (gi) lesions, dyspeptic symptoms, h.pylori infection, and the impact of duration of dialysis on upper gi symptoms and lesions of children with end-stage renal disease. we studied 69 children with esrd who were under regular hemodialysis therapy in our department. the age of the patients were between 4-18 years (mea...

To define more completely regional coronary hemodynamic changes that occur during spontaneous angina pectoris in patients with variant angina, we measured coronary sinus and great cardiac vein blood flow (CSF and GCVF) and aortic and left ventricular pressures before and during spontaneous angina in six patients with variant angina. During spontaneous angina, ECGs in four patients showed eviden...

OBJECTIVES The purpose of this study was to determine if ranolazine improves angina in stable coronary patients with persisting symptoms despite maximum recommended dose of amlodipine. BACKGROUND Ranolazine is a unique antianginal agent that has been effective in stable angina, but it has not been studied in the setting of maximum recommended doses of conventional antianginal agents. METHOD...
