Insights
Permanent pacemaker implantation (PPI) has a low complication rate, primarily linked to the capsular bag. Older age, high BMI, smoking, poor nutrition, and low platelets are key risk factors for PPI complications.
Area of Science:
- Cardiology
- Medical Device Technology
- Surgical Outcomes
Background:
- Permanent pacemaker implantation (PPI) is a common treatment for chronic arrhythmias.
- Understanding PPI's postoperative complication rates and associated risk factors is crucial for patient care.
Purpose of the Study:
- To determine the incidence of postoperative complications following permanent pacemaker implantation (PPI).
- To identify independent risk factors associated with these complications in patients undergoing PPI.
Main Methods:
- Retrospective analysis of clinical data from 124 patients who underwent PPI between January 2014 and January 2018.
- Collected and analyzed data on patient demographics, disease status, and postoperative complications.
- Employed unconditional single-factor and multivariate logistic regression to identify risk factors.
Main Results:
- The overall incidence of postoperative complications was 8.06% (10/124), with capsular hematoma, rupture, and infection being most common.
- Older age, high body mass index (BMI), smoking history, poor nutritional status, and decreased platelet counts were significantly associated with increased complication rates.
- Multivariate analysis confirmed these factors as independent predictors of postoperative complications.
Conclusions:
- Postoperative complications after PPI are infrequent and mainly involve the capsular bag.
- Older age, high BMI, smoking, poor nutrition, and low platelet count are significant independent risk factors for PPI complications.
- These findings highlight the importance of considering patient-specific risk factors to optimize outcomes after permanent pacemaker implantation.
Background:
Permanent pacemaker implantation (PPI) is widely used for the treatment of chronic arrhythmia. The aim of the present study was to investigate the incidence of postoperative complications and the risk factors in patients with PPI.
Methods:
The clinical data of 124 patients who underwent PPI in our hospital from January 2014 to January 2018 were collected and analyzed retrospectively. Data on sex, age, status of disease, and related complications of all patients were recorded, and differences were compared. The factors affecting postoperative complications in patients with PPI were analyzed.
Results:
The incidence of postoperative complications in 124 patients with PPI was 8.06% (10/124), including 4 cases with capsular hematoma (3.23%), 2 cases with capsular rupture (1.61%), 3 cases with capsular infection (2.42%) and 1 case with venous thrombosis (0.81%). Unconditional single-factor logistic regression model showed that the incidence of postoperative complications in patients with PPI was significantly greater with older age, high body mass index (BMI), smoking history, poor nutritional status, and decreased platelet counts (P<0.05). Results of the unconditional multivariate logistic regression analysis showed that older age, high BMI, smoking history, poor nutritional status, and decreased platelet counts were all independent risk factors of postoperative complications in patients with PPI (P<0.05).
Conclusions:
The incidence of postoperative complications in patients with PPI was low, and the complications were mainly related to capsular bag. Factors, such as older age, high BMI, smoking history, poor nutritional status, and decreased platelet counts, were independent risk factors resulting in postoperative complications in patients with PPI.
