Background And Aims: Although the phase angle (PhA), a measure of frailty and sarcopenia, determined by bioelectrical impedance analysis has been reported as a prognostic factor after cardiovascular surgery, few studies have reported the trajectory of the PhA after discharge. In this study, we examined the trajectory of the PhA along with conventional physical function measures and explored the factors associated with recovery for 6 months after hospital discharge in patients who had undergone cardiovascular surgery.
Methods: We included 116 patients who underwent elective cardiovascular surgery and cardiac rehabilitation after discharge.
Article Synopsis
- The study focused on the prognostic value of phase angle (PhA), a measure of cellular health, in predicting long-term mortality among older patients undergoing cardiovascular surgery.
- Researchers conducted a retrospective analysis of 858 patients who underwent surgery from October 2016 to March 2021, measuring PhA and various physical function metrics like gait speed and grip strength before the surgeries.
- Results indicated that higher PhA levels correlated with better physical function and were linked to improved survival rates after surgery, emphasizing the potential use of PhA as a valuable prognostic indicator.
Objectives: Cardiac rehabilitation (CR) is a class I recommendation in the treatment guidelines for cardiovascular disease; however, its postoperative prognostic effects after surgery are not fully understood. Therefore, this study aimed to examine the effect of multidisciplinary outpatient CR on postdischarge all-cause mortality in patients who underwent cardiovascular surgery.
Methods: This retrospective cohort study included consecutive patients who underwent elective cardiovascular surgery between April 2015 and March 2021.
Background: This study aimed to clarify factors affecting changes in moderate to vigorous physical activity (MVPA) in patients 1 to 3 months after undergoing percutaneous coronary intervention (PCI).
Methods: In this prospective cohort study, we enrolled patients aged <75 years who underwent PCI. MVPA was objectively measured using an accelerometer at 1 and 3 months after hospital discharge.
Article Synopsis
- The study investigates the impact of arm circumference (AC) on the clinical outcomes of patients undergoing transcatheter aortic valve replacement (TAVR), highlighting a lack of existing data on this anthropometric measurement.* -
- It divides patients into low and high AC groups and finds that those with low AC demonstrate greater frailty, with a higher risk of mortality independently associated with low AC values (HR: 2.56).* -
- The inclusion of AC in conventional survival prediction models improves accuracy in forecasting patient outcomes after TAVR, suggesting AC should be considered in treatment decisions.*
Background: Cardiovascular surgery leads to postsurgical muscle weakness, probably because of muscle proteolysis and peripheral nerve dysfunction, which are augmented by aging and diabetes mellitus.
Objective: We examined the effect of neuromuscular electrical stimulation (NMES) on postsurgical muscle weakness in older individuals with diabetes mellitus.
Methods: We conducted a multicentre, randomized, controlled trial, and screened consecutive patients with diabetes who underwent cardiovascular surgery for eligibility (age ≥ 65 years).
Article Synopsis
- Obesity is a significant risk factor for coronary artery disease, but its impact on atherosclerosis progression varies by age after percutaneous coronary intervention (PCI).
- A study divided patients into two groups (middle-aged and elderly) to assess obesity's effect on revascularization for new lesions within two years post-PCI, finding a notable correlation in middle-aged patients.
- Results suggest obesity may not predict complications in elderly patients, indicating that treatment strategies for preventing revascularization should consider the patient's age.
