Abstract
Background: Inferior myocardial infarction complicated by right ventricular infarction is associated
with a greater risk of in-hospital mortality and cardiovascular related complications. Early risk
stratification of patients with right ventricular infarction is crucial for appropriate management
and reduction of adverse cardiac events. The development of TIMI risk score has provided
a useful tool to quickly and easily stratify patients with right ventricular infarction. We conducted
this study to evaluate the prognostic value of TIMI Risk Score analysis in patients with right
ventricular infarction.
Methods: This observational study was conducted in the department of Cardiology in NICVD,
Dhaka, from July 2006 to June 2008. Considering inclusion and exclusion criteria, a total of 60
patients with right ventricular infarction were evaluated. All the patients were evaluated clinically
and ECG was done after admission. Patients were categorized into two groups by TIMI risk scoring.
Patients with low TIMI risk score(0-3) were in Group-I and patients with high TIMI risk score(4-
14) were in Group-II.
Results: The study revealed no statistically significant difference among the patients of two groups
(p>0.05) in relation to sex, weight, risk factors and presenting complaints. Analysis revealed
statistically significant difference among the patients of two groups (p<0.05) in relation to age,
duration of chest pain, clinical parameters, Killip class of heart failure and LVEF. Regarding inhospital
outcome, 51.7% patients developed complications during the study period and all the
complications were more in group II patients with high TIMI risk score(4-14). Death (18.3%) was the
most common complication followed by cardiogenic shock (15.0%), complete heart block(6.6%),cardiac
arrest(6.6%),VT(3.3%)and 2nd degree heart block(1.6%).
Conclusion: This study indicates that on admission - TIMI risk score analysis can identify patients
with right ventricular infarction at higher risk for in-hospital mortality and morbidity.
