Late outcomes of open heart surgery in patients 70 years or older

BACKGROUND The purpose of this study is to examine the long-term survival and quality of life, including the influence of comorbidities, in patients 70 years of age and over after open heart surgery. METHODS This was a retrospective study of 401 consecutive patients, who were 70 years of age or older at the time of surgery. Survival and quality of life of these patients were measured at 6- to 8-year follow-up. RESULTS The 5-year survival rate was 85%, and was comparable with the age- and gender-matched West Virginia population. Survival declined with increasing preexisting comorbidities. Of the 176 respondents completing the quality of life (SF-36) survey, most scores were similar to or substantially better than the US population normative scores for individuals 70 years of age or older. CONCLUSIONS Survival rates vary by presence or absence of specific comorbid conditions. Quality of life in the appropriately selected elderly after open heart surgery appears to be similar to the US population normative scores.

Short-duration oral amiodarone for prevention of atrial fibrillation post heart surgery

BACKGROUND Atrial fibrillation occurs in 20% to 40% of patients post cardiac surgery. Prophylactic amiodarone decreases the incidence of atrial fibrillation, especially in those not taking β-blockers. Studies, however, vary in dosage, duration of treatment, and route of administration. Limited studies evaluating short duration use of oral amiodarone show conflicting results. We hypothesize that an order set for use of short duration, oral amiodarone started the night before surgery and continued for 4 to 6 days will decrease atrial fibrillation after heart surgery. METHODS The Society of Thoracic Surgeons database was used to identify 471 patients who received amiodarone per order set and 151 patients that did not receive amiodarone. The amiodarone order set included amiodarone 600 mg the night before surgery and 400mg twice daily for 4 to 6 days post heart surgery. After propensity matching, 112 patients remained in each group. We compared outcomes for the 2 groups as a case-controlled, retrospective, study. RESULTS Atrial fibrillation occurred in 43% (48 of 112) of the patients that did not receive amiodarone vs 23% (26 of 112) receiving prophylactic amiodarone (P=<.001). There was no increased incidence of hemodynamic, pulmonary, or other adverse outcomes observed between the 2 groups. CONCLUSIONS This practical order set for, short duration, oral amiodarone, with or without adjunct β-blocker therapy started the night before heart surgery and continued for up to six days post surgery, appears to be a safe and effective treatment for reducing the incidence of atrial fibrillation following heart surgery.

Telehealth electronic monitoring to reduce postdischarge complications and surgical site infections after arterial revascularization with groin incision

It is intuitive that postdischarge surgical complications are associated with increased patient dissatisfaction, and are directly associated with an increase in medical expenditures. It is also easy to make the connection that many post-hospital discharge surgical complications, including surgical site infections (SSIs), could be influenced or exacerbated by patient comorbidities. The authors of a recent study reported that female gender, obesity, diabetes, smoking, hypertension, coronary artery disease, critical limb ischemia, chronic obstructive pulmonary disease, dyspnea, and neurologic disease were significant predictors of SSIs after vascular reconstruction was performed. The main concern for optimal patient care, especially in geographically isolated areas of West Virginia, is to have early, expeditious, and prompt diagnosis of complications and SSI. This adjunct to existing approaches could lead to improved outcomes and patient satisfaction, minimizing third-party interventions and decreasing the total cost of care. It seems reasonable to believe that monitoring using telehealth technology and managing the general health care of patients after a hospital vascular intervention will improve overall health and reduce 30-day readmissions and SSIs.
