Objective: To determine the frequency of infections in cardiac implantable Electronic device patients, identify risk factors, and look for optimization in reducing Cardiac Implantable Electronic Device infections, with a resultant decrease in mortality and morbidity, decrease in hospital stay, and total expenditure.
Study Design: Cross-sectional study.
Place and Duration of Study: Electrophysiology Department of National Institute of Cardiovascular Diseases, Karachi
Pakistan, from Jul 2019 to Jun 2020.
Methodology: The study was conducted on the patients with cardiac implantable devices. Adult patients of either gender
with cardiac implantable Electronic device and infection were included. Epicardial leads and surgical site infections within six
weeks were excluded.
Results: One thousand and forty-six (1046) patients were enrolled in the study. There were 596(57%) male patients.
385(36.8%) patients were implanted with single chamber pacemakers, 390(37.3%) with dual chamber pacemakers, 146(14%)
single chamber ICD (implantable cardiac defibrillator), 67(6.4%) dual-chamber cardiac implantable Electronic device, 46(4.4%) CRT-D, 12(1.1%) TPM, 134(12.8%) Re-do, 114(10.9%), 114(10.9%) generator change, 20(1.9%) leads revision, 26(2.5%) patients had extraction. The rate of CIED infection was 34(2.1%). The association of the study parameters with infection rate revealed that type of device (p=0.002), extraction, suture type, and post-procedure hematoma (p<0.001) had a statistically significant relationship with infection rate.
Conclusion: The Cardiac Implantable Electronic Device infection rate was 2.1%. Hypertension and diabetes were common risk factors, and left ventricular dysfunction was common in high-energy devices with multiple leads and repeated procedures.
