Lars H. Lund, M.D., Ph.D., of the Karolinska Institutet, Stockholm, Sweden, and colleagues conducted a study to examine whether beta-blockers are associated with reduced mortality in heart failure patients with preserved ejection fraction (a measure of how well the left ventricle of the heart pumps with each contraction).The study appears in the Nov.

Overall death rate from heart disease declines, although increase seen for certain types
