Aim of the work To study the extent of right ventricular (RV) dysfunction in ischemic patients after coronary artery bypass grafting (CABG). Patients and methods RV function was studied preoperatively and followed for 1 month postoperatively in 40 patients who were scheduled for elective coronary artery bypass surgery and in other 40 controls. We evaluated RV function by tissue Doppler study of the tricuspid annulus and the basal septum, tricuspid annular plane systolic excursion, and RV dimensions. Both LV dimensions, left atrium dimensions, and aortic root dimensions were also measured before and after surgery. Results RV function was significantly reduced …

The Relation Between Heart Rate Response During Exercise And Angiographic Severity In Patients With Chronic Coronary Syndrome, Emmanuel Louka
Journal of Medicine in Scientific Research
Introduction Ellestad and colleagues, in 1975, reached to the conclusion that impaired heart rate response to exercise carries a similar risk for future coronary events such as ischemic ‘ST’ segment changes. Mc Neer and colleagues went beyond these observations to include a survival benefit in patients who achieve a higher peak heart rate (PHR), a more advanced level of exercise, and have a normal exercise electrocardiogram. Aim The aim of this work is to clarify the relation between the chronotropic response to exercise and the severity of coronary artery disease in patients with chronic coronary syndrome. Patients and methods The …
