Insights
High homocysteine (Hcy) levels are linked to vascular issues and cardiovascular disease. While vitamin supplements may lower Hcy, their impact on reducing cardiovascular events requires further clinical study.
Area of Science:
- Cardiovascular Science
- Vascular Biology
- Clinical Biochemistry
Context:
- Hyperhomocysteinemia (Hcy) is associated with endothelial dysfunction and coagulation abnormalities.
- Epidemiological studies link Hcy to premature arteriosclerosis, stroke, myocardial infarction, and peripheral vascular diseases, independent of conventional risk factors.
- Pilot study demonstrated elevated Hcy levels in patients with ischemic heart disease compared to controls.
Purpose:
- To investigate the association between homocysteine levels and ischemic heart disease.
- To evaluate the potential role of homocysteine as a risk factor for cardiovascular diseases.
- To underscore the need for further clinical and epidemiological studies on Hcy and cardiovascular outcomes.
Summary:
- Hyperhomocysteinemia negatively impacts vascular endothelium and coagulation.
- Clinical studies have proven the association of Hcy with premature arteriosclerosis, stroke, and other vascular diseases.
- Vitamin supplementation (folates, B6, B12) can reduce Hcy levels, but its effect on cardiovascular disease incidence and mortality remains unproven.
Impact:
- Highlights the clinical significance of hyperhomocysteinemia in cardiovascular pathology.
- Emphasizes the need for further research into the therapeutic benefits of homocysteine-lowering strategies.
- Provides a foundation for future clinical trials investigating homocysteine-targeted interventions for cardiovascular disease prevention.
Abstract:
Hyperhomocyst(e)mia (Hcy) negatively influences vascular endothelium and coagulation factors. Association of Hcy with premature arteriosclerosis (rather than atherosclerosis), stroke, myocardial infarction and peripheral arterial and venous disease was proved in clinical and epidemiological studies, even as the association with conventional risk factors like age, male sex, smoking, hypertension and hypercholesterolemia. Vitamin substitution of folates, vitamin B6 and B12 decreases Hcy blood levels, however definite evidence is still lacking, whether it results in lower incidence and mortality from cardiovascular diseases. Therefore clinical and epidemiological studies are necessary. Before the grant-application we proved in a pilot study significantly higher Hcy levels in 97 patients with manifest ischaemic heart disease than in 37 controls.
