Coronary risk factor screening in three rural communities. The CORIS baseline study

Area of Science:

• Cardiology
• Epidemiology
• Public Health

Background:

• Ischemic heart disease (IHD) poses a significant health burden globally.
• Understanding risk factor prevalence is crucial for targeted prevention strategies.
• Previous research has indicated potential genetic predispositions within specific populations.

Purpose of the Study:

• To investigate the prevalence of major reversible and irreversible risk factors for IHD.
• To assess the combined impact of these risk factors in a rural Afrikaans-speaking White population.
• To inform preventive strategies for IHD in this community.

Main Methods:

• A three-community study was conducted in rural, Afrikaans-speaking White individuals.
• Data collection included assessment of hypercholesterolemia, hypertension, smoking, inactivity, obesity, hyperuricemia, coronary-prone behavior, chest pain, ECG changes, and family history.
• Prevalence rates were analyzed across different age groups, particularly focusing on individuals over 44 years.

Main Results:

• Major reversible risk factors (hypercholesterolemia, hypertension, smoking) and irreversible factors (family history of IHD, ECG changes) were found to be exceedingly common.
• These major risk factors, individually or in combination, were present in the vast majority of the study population aged 44 and older.
• Minor risk factors like inactivity, obesity, and hyperuricemia were also prevalent.

Conclusions:

• The high prevalence of multiple IHD risk factors in this population suggests a significant public health concern.
• The interaction between lifestyle-induced risk factors and genetic predisposition likely contributes to excess IHD risk.
• The findings underscore the urgent need for comprehensive preventive strategies tailored to this community.
