Plasma homocyst(e)ine concentration, but not MTHFR genotype, is associated with variation in carotid plaque area.

BACKGROUND AND PURPOSE Elevated plasma homocyst(e)ine [H(e)] concentration is associated with premature atherosclerosis. A common cause of elevated plasma H(e) concentration is a thermolabile mutation (677T) in the gene encoding methylenetetrahydrofolate reductase (MTHFR). We sought to determine whether plasma H(e) concentration or MTHFR genotype would be more strongly associated with carotid p...

Carotid plaque burden is associated with higher levels of total homocysteine

There are several problems with the report of Li et al. They studied sex differences, not gender differences. They referred to carotid intima-media thickness (IMT) as atherosclerosis; it is not, and plaque burden is a much stronger predictor of cardiovascular risk than IMT. They referred to levels of homocysteine (Hcy), but almost certainly what they measured was total homocysteine (tHcy), whic...

Elevated Plasma Homocysteine Concentration in Opium-Addicted Individuals

Background: Although the triggering role of both opium use and elevated plasma homocysteine level for progressing atherosclerosis and, therefore, appearing coronary heart disease has been clearly determined, no study are available with respect to the relation between these to risk profiles. In the present study and for the first time, we hypothesized that the opium addiction can be potentially ...

Lipoprotein(a) is associated differentially with carotid stenosis, occlusion, and total plaque area.

BACKGROUND Lipoprotein(a) [Lp(a)] is a putative risk factor for myocardial infarction and stroke and is related to thrombosis and impaired fibrinolysis. We studied relationships of Lp(a) with carotid stenosis, occlusion, and total plaque area, distinct phenotypes of atherosclerosis that may be differentially affected by cardiovascular risk factors. METHODS AND RESULTS Multivariable linear reg...

Plasma Homocysteine Is Associated with Aortic Arterial Stiffness but not Wave Reflection in Chinese Hypertensive Subjects

OBJECTIVE Elevated plasma total homocysteine (tHcy) acts synergistically with hypertension to exert a multiplicative effect on cardiovascular diseases risk. The aim of this study was to determine the relationship between tHcy concentration and blood pressure, and to evaluate the role of plasma tHcy in arterial stiffness and wave reflection in hypertension. METHODS In this cross-sectional stud...
