The changing pattern of cardiovascular diseases in Ethiopia

Area of Science:

• Cardiology
• Public Health
• Epidemiology

Background:

• Cardiovascular diseases (CVDs) pose a significant health burden globally and in Ethiopia.
• Understanding the specific epidemiological trends of CVDs is crucial for targeted public health interventions.

Purpose of the Study:

• To analyze the prevalence and trends of various cardiovascular diseases in Ethiopian patients over a 20-year period.
• To identify the most common causes of heart disease and their demographic associations.

Main Methods:

• Retrospective study of 474 patients with cardiovascular diseases.
• Data collected from the cardiac clinic of Gondar College of Medical Science Hospital, Ethiopia, between 1985 and 1988.
• Comparison of disease incidences with data from a previous 20-year period.

Main Results:

• Rheumatic heart disease was the most common (42%), predominantly affecting young people with advanced valvular lesions.
• Hypertension was the second most common cause (38.1%), with 77% being essential hypertension, also affecting young individuals.
• Significant increases in rheumatic and hypertensive heart diseases were observed. Myocardial infarction incidence rose from 0.88 to 6.4 per 1000 over 20 years.

Conclusions:

• Rheumatic and hypertensive heart diseases are increasingly prevalent in Ethiopia, disproportionately affecting the young population.
• While some CVDs like syphilitic heart disease and cardiomyopathy have decreased, the rise in myocardial infarction is notable.
• Public health strategies should focus on addressing the growing burden of rheumatic and hypertensive heart diseases in Ethiopia.
