A study of spectrum of rheumatic heart disease in a tertiary care hospital in Central Nepal.

Background And Aims: Rheumatic heart disease is one of the most common cause for heart failure and associated mortalities/morbidities in the young population in developing countries like Nepal imparting huge familial, social and manpower burden.

Materials And Methods: This is a hospital based descriptive cross-sectional study during June 2014 to April 2016 over a period of 22 months at College of Medical Sciences-Bharatpur including 235 patients with clinical and/or echocardiographic evidence of definite rheumatic heart disease.

Results: The age of the patients ranged from 7 to 76 years with mean age 39.82 ± 4.2 years with female preponderance (F:M = 2.1:1) ( < 0.01). Majority of the rheumatic heart disease patients belonged to 30-44 years (28.78%) followed by 15-29 years (25.75%) and 45-59 years (25.00%). Majority belonged to the low socioeconomic status (60.60%) ( < 0.05). The predominantly involved isolated valve was mitral in 110 patients (46.80%) followed by isolated aortic valve in 22 patients (9.36%) and 79 (33.62%) had dual valvular involvement. The common rheumatic valvular lesions were pure mitral stenosis in 32 (13.61%), isolated mitral regurgitation in 58 (24.68%), combined mitral stenosis/regurgitation in 36 (15.32%), combined mitral/aortic regurgitation in 23 (9.78%) and combined aortic stenosis/regurgitation in 18 (7.66%) patients with few overlappings. The common complications encountered were heart failure in 90 (38.30%) and arrhythmias in 124 (51.00%) patients.130 patients (55.32%) received injectable benzathine penicillin whereas 45 patients (19.15%) preferred oral penicillin V. Surgical intervention was done in 54 (22.97%) patients. 12 (5.10%) expired in the CCU during the course of treatment.

Conclusion: RHD is a leading cause of heart failure among young populations with requirement of prolonged duration of medical treatment and many of them requiring surgery.
