Articles

  • A mildly to moderately elevated nonfasting total homocysteine level is a substantial risk marker for death from any cause. The association seems to be stronger during the first 5 years of follow-up.

  • Upper reference limits for serum total homocysteine concentration increased with age and were higher for male participants than for female participants at all ages. In most cases, high homocysteine concentrations were associated with low serum vitamin levels.

  • Bloodstream infections seem to be infrequent among outpatients receiving infusions through central and midline catheters. However, the rate of infection increases with bone marrow transplantation, parenteral nutrition, infusion therapy in a hospital clinic or physician's office, and use of multilumen catheters.

Brief Communications

  • Hypothyroidism may be a treatable cause of hyperhomocysteinemia, and elevated plasma homocysteine levels may be an independent risk factor for the accelerated atherosclerosis seen in primary hypothyroidism.

  • Nonfasting total homocysteine levels are an independent risk factor for incident stroke in elderly persons.

Reviews

  • This paper reviews the relation between homocyst(e)ine levels and risk for cardiovascular disease and the potential cardiovascular risk reduction associated with therapy to decrease homocyst(e)ine levels.

  • Recent studies have identified several potential new cardiovascular risk factors, including left ventricular hypertrophy, homocysteinemia, lipoprotein(a) excess, hypertriglyceridemia, oxidative stress, and hyperfibrinogenemia. This review summarizes the current literature that supports these conditions as risk factors.

Editorials

  • Is an elevated plasma homocysteine level bad for you? Although the association between genetic hyperhomocysteinemia and vascular disease would clearly indicate that an increased homocysteine level precedes the disease, these issues have not been definitively resolved. Several papers in this issue address this topic.

  • The turn of the millennium will mark the end of the third year of the Medical Writings section in Annals. How successful has this section been, and what lies ahead for it?

Updates from the Annual Session

  • The results of several studies published in 1998 were important to the practice of cardiology. The main areas of interest were evaluation of chest pain, acute coronary syndromes, valvular heart disease, congestive heart failure, and coronary risk factors.
