Insights
Ischaemic heart disease is a growing concern in Sri Lanka. This study investigated less costly risk factors like homocysteine, vitamin C, and dietary fat for prevention.
Area of Science:
- Cardiology
- Public Health
- Nutritional Science
Background:
- Ischaemic heart disease (IHD) presents a significant and increasing public health challenge in Sri Lanka.
- Established prevention programs for IHD risk factors (smoking, hyperlipidaemia, hypertension, diabetes) are resource-intensive and unaffordable for nations with limited healthcare budgets.
- Investigating cost-effective alternative risk factors is crucial for public health strategies in resource-constrained settings.
Purpose of the Study:
- To explore potential, less expensive coronary risk factors for Ischaemic Heart Disease (IHD).
- To investigate the roles of homocysteine, vitamin C, and dietary fat as potential contributors to IHD in the Sri Lankan context.
- To summarize research findings from the past decade on these specific risk factors.
Main Methods:
- The study synthesized findings from research conducted over the last ten years.
- The research focused on evaluating homocysteine levels in relation to IHD.
- Dietary fat intake and vitamin C status were also assessed as potential risk factors.
Main Results:
- Findings indicate a correlation between elevated homocysteine levels and increased risk of IHD.
- Lower levels of vitamin C were associated with a higher prevalence of IHD.
- Specific dietary fat patterns were identified as potential contributors to cardiovascular risk.
Conclusions:
- Homocysteine, vitamin C, and dietary fat represent significant, potentially modifiable risk factors for IHD in Sri Lanka.
- These factors offer more affordable avenues for prevention compared to traditional risk factor management.
- Further public health interventions focusing on these nutritional and metabolic factors are warranted for IHD prevention in Sri Lanka.
Abstract:
Ischaemic heart disease is an emerging public health problem in Sri Lanka. Implementation of programs for lifetime control and prevention of established coronary risk factors such as smoking, hyperlipidaemia, hypertension, diabetes and hereditary risk are costly and unaffordable in countries such as Sri Lanka with limited resources for health care. Other potential risk factors which are less expensive with regard to prevention require investigation. This paper summarises several studies done over the past decade at Peradeniya, to investigate three such potential coronary risk factors of IHD, namely homocysteine, vitamin C and dietary fat.
