Enlarged Heart

Photo: Normal versus enlarged heart
Martti Tenhu, chief medical examiner in Helsinki, Finland, illustrates the differences between a normal human heart and one enlarged by alcoholism and high blood pressure. Covered in scar tissue, the enlarged organ is nearly twice the normal size. Such alcoholic cardiomyopathy weakens the heart so that it is unable to pump blood adequately.
