Insights
Frailty is common in patients undergoing heart surgery, even younger ones. Frail patients face significantly higher hospital mortality after procedures like coronary artery bypass grafting and heart valve surgery.
Area of Science:
- Cardiology
- Geriatrics
- Surgical Outcomes
Background:
- Frailty, often associated with aging, can affect younger individuals with chronic diseases.
- Frailty is a known risk factor that can increase operative risk.
Purpose of the Study:
- To determine the prevalence of frailty in patients undergoing coronary artery bypass grafting (CABG) and/or heart valve surgery.
- To assess the impact of frailty on postoperative outcomes in cardiac surgery patients.
Main Methods:
- 100 adult patients undergoing elective cardiac operations were assessed.
- Frailty was evaluated using the Fried scale, supplemented by a 6-minute walk test and respiratory pressure measurements.
Main Results:
- 17% of patients were frail, 70% pre-frail, and 13% non-frail, with 53% of frail patients under 60.
- Hospital mortality was significantly higher in frail patients (29.4%) compared to pre-frail (8.6%) and non-frail (0%) groups.
Conclusions:
- Frailty is prevalent in non-elderly patients undergoing CABG or valvular heart surgery.
- Frailty is significantly associated with increased postoperative hospital mortality in this patient population.
Background:
Usually viewed as a characteristic of old age, frailty may also occur in non-elderly people, primarily in those suffering from chronic disease. Frailty may increase operative risk.
Objectives:
To determine the prevalence of frailty patients undergoing coronary artery bypass (CABG) and/or heart valve replacement or reconstruction and/or heart valve surgery, as well as the influence of frailty on postoperative outcomes.
Methods:
Our study comprised 100 adults who underwent consecutive elective cardiac operations. Frailty was assessed using the Fried scale. Patients also performed a 6-minute walk test, and we measured maximal inspiratory and expiratory pressures. A p value <0.05 was considered significant.
Results:
Of a cohort of 100 patients, based on the Fried frailty criteria, 17 patients (17%) were considered frail, 70 (70%) pre-frail and only 13 (13%) were non-frail. Among patients with valvular heart disease, 11 (18.6%) were considered frail and 43 (73%) pre-frail. Fifty three percent of the patients considered frail were less than 60 years old (median=48 years old). The differences in frailty phenotype between patients with valvular heart disease and coronary artery disease were not statistically significant (p=0.305). A comparison between non-frail, pre-frail, and frail patients showed no significant difference in the distribution of comorbidities and cardiac functional status, regardless of their cardiac disease. However, hospital mortality was significantly higher in frail patients (29.4%, p=0.026) than in pre-frail patients (8.6%) and non-frail patients (0%).
Conclusions:
Frailty is prevalent even among non-elderly patients undergoing CABG or valvular heart surgery and is associated with higher postoperative hospital mortality.
