Insights
Coronary artery bypass grafting outcomes vary by age, with older patients (over 75) experiencing more bleeding complications. Personalized treatment strategies are crucial for optimal results in myocardial revascularization.
Area of Science:
- Cardiology
- Cardiac Surgery
- Geriatric Medicine
Background:
- Myocardial revascularization addresses ischemic heart disease using various invasive methods.
- Patient age is a significant factor influencing treatment strategies and outcomes.
Purpose of the Study:
- To investigate the outcomes of coronary artery bypass grafting (CABG) across different age groups.
- To identify age-related differences in complication rates following CABG.
Main Methods:
- A cohort of 905 patients undergoing CABG was stratified into four age groups: young, middle, old, and senile.
- Follow-up endpoints included myocardial infarction, stroke, death, and hemorrhagic complications.
Main Results:
- No significant differences in overall postoperative complication rates were observed between age groups.
- Patients over 75 years old showed a higher incidence of mediastinal revision due to hemorrhage.
Conclusions:
- Age groups undergoing CABG exhibit significant heterogeneity in clinical and intraoperative characteristics.
- Increased hemorrhagic complications in older patients may stem from aggressive anticoagulation/antiplatelet therapy, often due to atrial fibrillation.
- An individualized approach to revascularization strategy is paramount for optimizing outcomes in coronary surgery.
Background:
Myocardial revascularization involves a wide range of invasive strategies aimed at treating ischaemic heart disease in patients of different age groups.
Aim:
The purpose of the present study was to analyze the outcomes of coronary artery bypass grafting in patients depending on age.
Patients And Methods:
A total of 905 patients enrolled in our study were subdivided into groups based on age-related characteristics (young age, middle age, old age, senile age). The endpoints of follow up were as follows: myocardial infarction, acute impairment of cerebral circulation, death and haemorrhagic complications.
Results:
It should be mentioned that the groups were comparable by the majority of the parameters studied. No statistically significant differences in the frequency of the development of complications in the postoperative period were observed. However, amongst patients over 75 years old, revision of the mediastinum for haemorrhage was performed more often.
Discussion:
Patients of different age groups undergoing coronary artery bypass grafting are extremely heterogeneous by the clinical, anamnestic, instrumental and intraoperative characteristics. A high frequency of haemorrhagic complications amongst patients over 75 years old may be explained by a more aggressive approach to the regimens of anticoagulant/antiaggregant therapy resulting form the presence of atrial fibrillation. In its turn, this fact determines the probability of a high frequency of the development of adverse cardiovascular events. An individual approach to the choice and scope of the strategy of revascularization in patients of different age groups is the fundamental principle for an optimal outcome of coronary surgery.
Conclusion:
The obtained findings and analysis of the statistical data are indicative of the necessity of personified selection of the technique of a surgical intervention for each particular patient, which will make it possible to decrease the rate of adverse cardiovascular events in the postoperative period.
