Coronary heart disease risk assessment

Area of Science:

• Cardiology
• Public Health
• Primary Care Medicine

Background:

• Coronary heart disease (CHD) is a significant public health concern.
• Accurate risk assessment is crucial for effective CHD prevention strategies.
• Patient self-perception of risk can influence health behaviors.

Purpose of the Study:

• To evaluate the relationship between existing cardiovascular disease (CVD), risk factors, and self-perceived CHD risk in rural primary care patients.
• To identify factors associated with underestimation or overestimation of CHD risk.
• To compare perceived risk with actual risk based on established risk profiles.

Main Methods:

• Cross-sectional study of 883 patients in two rural primary care practices.
• Assessment of self-perceived CHD risk and presence of cardiovascular disease.
• Analysis of demographic factors, socioeconomic status, and anxiety levels.
• Application of Framingham risk profiles for objective risk stratification.

Main Results:

• Patients with existing CVD were more likely to perceive higher risk, but 16% underestimated their risk.
• Patients without CVD sometimes overestimated risk (19%), often linked to disability and anxiety.
• Self-perceived risk was not significantly altered by most risk factors, except family history.
• Objective risk assessment revealed 7.3% of eligible patients had elevated Framingham risk scores.
• Women reported significantly lower risk estimates than men.

Conclusions:

• A notable discrepancy exists between perceived and actual CHD risk in primary care patients.
• Understanding self-perceived risk is vital for tailoring interventions.
• Healthcare providers should assess both perceived and objective risk for effective CHD management.
