IMPACT OF PREOPERATIVE ANEMIA ON OUTCOME IN PATIENTS UNDERGOING CORONARY ARTERY BYPASS GRAFT SURGERY, by Kulier et al. |
|---|
Anemia is an increasingly frequent clinical finding and is known to be associated with increased morbidity and mortality, especially in patients with coronary artery disease and in the perioperative setting. The observational study by Kulier and colleagues documents the clinical course of more than 5000 patients undergoing coronary artery bypass surgery, describing the impact of low preoperative hemoglobin levels on postoperative outcomes and delineating the influence of comorbidities and other risk factors on individual tolerance to anemia. Anemic patients with few additional risk factors have increased postoperative renal and cerebral complications only, whereas high-risk patients show an additional propensity for cardiac adverse events. Although the increase in noncardiac postoperative complications was independently associated with low preoperative hemoglobin levels, cardiac adverse events were caused by other factors, all of which are frequently present in anemic patients. Thus, a patient’s perioperative risk has to be assessed individually, considering both the hemoglobin level and other comorbid conditions. The best therapeutic strategies to reduce the perioperative risk of anemic patients are still unknown and require further investigation. See p 471 (editorial p 458).

SOFT DRINK CONSUMPTION AND RISK OF DEVELOPING CARDIOMETABOLIC RISK FACTORS AND THE METABOLIC SYNDROME IN MIDDLE-AGED ADULTS IN THE COMMUNITY, by Dhingra et al. |
|---|
Soft drink consumption has been linked to childhood and adolescent obesity, but it is unclear if it increases metabolic risk in middle-aged individuals. In this issue of Circulation, Dhingra and colleagues use data from the community-based Framingham Heart Study to relate soft drink consumption to the development of metabolic syndrome and its components. The authors report that individuals who consumed at least 1 soft drink per day were more
