Race and treatment for heart failure.

Beta-blockers and ace-inhibitors:

  • Efficacy of angiotensin-converting enzyme inhibitors and beta-blockers in the management of left ventricular systolic dysfunction according to race, gender, and diabetic status: a meta-analysis of major clinical trials.

    Summary: "Angiotensin-converting enzyme inhibitors and beta-blockers provide life-saving benefits in most of the subpopulations assessed. Women with asymptomatic LV systolic dysfunction may not achieve a mortality benefit when treated with ACE inhibitors."

Isosorbide dinitrate and hydralazine combination:

Key study:

Combination of isosorbide dinitrate and hydralazine in blacks with heart failure.

N Engl J Med 2004;351(20):2049-57. PMID: 15533851
PubMed: Abstract
Fulltext options: N Engl J Med website - CrossRef - EBSCO - OVID
Summary: "The addition of a fixed dose of isosorbide dinitrate plus hydralazine to standard therapy for heart failure including neurohormonal blockers is efficacious and increases survival among black patients with advanced heart failure."

Background:

1. A comparison of enalapril with hydralazine-isosorbide dinitrate in the treatment of chronic congestive heart failure.

N Engl J Med 1991;325(5):303-10. PMID: 2057035

Vasodilator therapy should be included in the standard treatment for heart failure. The different effects of the two regimens (enalapril and hydralazine-isosorbide dinitrate) on mortality and physiologic end points suggest that the profile of effects might be enhanced if the regimens were used in combination.

2. Effect of vasodilator therapy on mortality in chronic congestive heart failure. Results of a Veterans Administration Cooperative Study.

Summary: " Left ventricular ejection fraction (measured sequentially) rose significantly at eight weeks and at one year in the group treated with hydralazine and isosorbide dinitrate but not in the placebo or prazosin groups. Our data suggest that the addition of hydralazine and isosorbide dinitrate to the therapeutic regimen of digoxin and diuretics in patients with chronic congestive heart failure can have a favorable effect on left ventricular function and mortality."
