The developing world in The New England Journal of Medicine.

Background: Rampant disease in poor countries impedes development and contributes to growing North-South disparities; however, leading international medical journals underreport on health research priorities for developing countries.

Methods: We examined 416 weekly issues of the New England Journal of Medicine (NEJM) over an eight-year period, January 1997 to December 2004. A total of 8857 articles were reviewed by both authors.

Unanswered ethical and scientific questions for trials of invasive interventions for coronary disease: The case of single vessel disease.

Trials in the 1990s demonstrated that medical therapy is as effective as invasive therapies for treating single-vessel coronary disease. Yet more recent studies enrolling patients with this condition have focused on evaluating only invasive approaches, namely, stenting versus coronary artery bypass surgery. Several ethical and scientific questions remain unanswered regarding the conduct of these later trials.

Long-term outcomes of optimized medical management of outpatients with stable coronary artery disease.

The objective of this study was to assess long-term clinical outcomes and their correlates in medically managed outpatients with stable angina pectoris, healed myocardial infarction (MI), or documented asymptomatic coronary artery disease (CAD). Management strategy emphasized maximally tolerated medical therapy and modification of coronary risk factors. Referral to invasive coronary interventions followed stricter criteria than standard published guidelines.
