A case control study of cardiovascular health in chemical war disabled Iranian victims.
BACKGROUND
Sulfur mustard (SM) is an alkylating chemical warfare agent that was widely used during Iran-Iraq war between 1983 and 1988. SM exposure leads to various late complications. The aim of this study was to determine the late cardiovascular effects of SM in war-disabled Iranian victims.


METHODS
This was a retrospective cohort case control study on 50 patients with symptoms of SM exposure and 50 cases who had been in Iran-Iraq war, without chemical injury. We performed exercise stress test and echocardiography for all of patients.


RESULTS
The study group comprised 100 males of mean age 45.6 ± 6.2 years. In chemical war injury group, two patients (4%) had positive exercise stress test. On coronary angiography, they were found to have coronary artery disease. One patient had severe mitral regurgitation and normal coronary angiography; he was referred for mitral valve replacement. Left ventricular (LV) diastolic abnormality was detected in 23% of these subjects. In another group, 5% had LV diastolic abnormality (P = 0.02) and all of them had normal stress test.


CONCLUSIONS
Cardiovascular abnormalities are another late complication in chemical war disabled Iranian victims. Diastolic dysfunction was the most common abnormality in both groups of patients.
