Abstract
Objective: To determine the frequency of various risk factors and their correlation with outcome in
patients having complete heart block. Methods: This Prospective cohort study was conducted at
Rawalpindi Institute of Cardiology, Rawalpindi for a duration of six months. A total of 153 patients
from both genders having complete heart block coming to Rawalpindi Institute of Cardiology were
recruited in the study. The patients included in the study were evaluated for aetiology of complete heart
block by history, physical examination, electrocardiography, blood tests, chest X-ray and
echocardiography. A proforma was designed and filled by duty doctor for each patient. The proforma
included demographic details, risk factors, presenting complaints, vitals and other parameters. The
outcome of these patients (pacemaker implantation/medical treatment/death) was determined in the
later part of the study and recorded on proforma. Results: Hypertension was the most common risk
factor (43.8%) observed in patients of complete heart block in our study. There was no significant
difference in the outcome in patients having risk factor of hypertension and smoking. However, a
significant difference was observed in frequency of pacemaker implantation in diabetics as compared to
non-diabetics (p=0.039). Conclusions: Hypertension was present in majority of complete heart block
patients. The outcome however was not affected by most of risk factors. Only in diabetic risk factor
group, significantly fewer numbers of patients were implanted with pacemaker. Death was also not
significantly correlated with any particular risk factor.
