... f ingestion of PPD were recorded after taking written consent from patients/attendants. Clinical presentation including sign and symptoms were recorded. The diagnosis of myocarditis was made solely on the basis of clinical signs/symptoms indicating myocardial damage, changes in electrocardiography, elevated cardiac biomarkers and trans-thoracic echocardiography abnormalities. Myocarditis-related mortality was reviewed. Data was analyzed by SPSS 24.0. Results: 88 (80 percent) were women out of 110 patients, while 22(20 percent) were males. The patients' mean age was 26.52±9.84 years. In 95.45 percent of cases, suicide was the most frequent cause of PPD ingestion. In 83 percent of cases, cervicofacial edoema was the most common symptom found. In 25 (22.73 percent) patients, myocarditis was found. 10(40 percent) of the 25 myocarditis patients died. The mortality rate overall was 27.27 percent. Conclusion: Myocarditis has been found to be highly associated with the ingestion of praphenylene diamine with a high mortality rate.
