Insights
High homocysteine (Hcy) levels increase mortality risk in men with atherosclerosis. However, long-term treatment with medications like Aspirin significantly improved survival rates in these patients.
Area of Science:
- Cardiovascular Medicine
- Clinical Research
- Biochemistry
Background:
- Hyperhomocysteinemia is a known risk factor for cardiovascular diseases, stroke, and venous thrombosis.
- Elevated homocysteine (Hcy) levels predict mortality in patients with ischemic heart disease.
Purpose of the Study:
- To investigate the long-term clinical outcomes of patients with atherosclerosis risk factors and high homocysteine concentrations.
- To assess the relationship between homocysteine levels and mortality in this patient cohort.
Main Methods:
- A 5-year follow-up study of 89 patients with atherosclerosis risk factors.
- Data collection included plasma total homocysteine (Hcy) levels, clinical examinations, medical record reviews (smoking, comorbidities, medications), and statistical analysis using SPSS.
- Patient outcomes, including survival, were monitored.
Main Results:
- Men with high Hcy concentrations had a significantly higher mortality rate (17%) compared to those with normal levels (P<0.05).
- Homocysteine levels did not impact survival in women.
- No association was found between Hcy and diabetes mellitus, hypercholesterolemia, or hypertension.
- Long-term treatment with Beta Blockers, ACE inhibitors, Calcium Channel blockers, and particularly Aspirin, significantly reduced mortality in patients with high Hcy (P<0.05).
Conclusions:
- Hyperhomocysteinemia may negatively affect survival in men.
- Medications including Beta Blockers, ACE inhibitors, Calcium Channel Blockers, and Aspirin can alter the natural course of high Hcy patients by preventing death.
Background:
Hyperhomocysteinemia confers an increased risk of coronary artery disease, stroke, and deep vein thrombosis, and is a strong predictor of mortality among patients with ischemic heart disease.
Purpose:
To determine the long term clinical outcome of patients with risk factors to atherosclerosis with high concentrations of homocysteine (Hcy).
Methods:
89 patients with one or more risk factors for atherosclerosis, whose plasma total Hcy concentrations were measured, were followed for 5 years. Patients were interviewed and underwent a clinical examination in the outpatient clinic. Their medical records were reviewed in the last 5 years including smoking habits, medications, other diseases (hypertension, diabetes mellitus, hyperlipidemia) and their management. SPSS was used to describe and explore possible relationships between Hcy concentration, other diseases, medications and the clinical long term outcome.
Results:
All men with normal Hcy concentrations (10.76+/-1.71 micromol/L) survived during the 5 years' follow up, while 5 of the men with high Hcy concentrations (21.27+/-5.37 micromol/L), died (17%) (P< 0.05). In women Hcy concentration did not affect survival. No association was found between diabetes mellitus, hypercholesterolemia, hypertension and Hcy. Long term treatment with Beta Blockers, ACE inhibitors, Calcium Channel blockers, and especially with Aspirin prevented death and changed the natural history of patients with high Hcy concentrations (P < 0.05).
Conclusions:
Hyperhomocysteinemia may have an effect on survival in men. Long term treatment with Beta Blockers, ACE inhibitors, Calcium Channel Blockers, and especially with Aspirin--prevented death and changed the natural history of patients with high Hcy concentrations.
