In spite of national interest in gender differences in the presentatio
n and management of chronic disease, limited information is available
about possible gender differences in the receipt of thrombolytic thera
py after acute myocardial infarction (AMI). As part of an ongoing comm
unity-based study of AMI, we examined gender differences in the receip
t of thrombolytic therapy among 2885 patients with confirmed AMI. The
study sample consisted of 1680 males and 1205 females with validated A
MI who were admitted to 16 hospitals in the Worcester, Massachusetts,
metropolitan area in four study periods between 1986 and 1991. During
the years under study, 24.4% of men and 14.4% of women received thromb
olytic therapy. Increases over time in the use of thrombolytic therapy
were seen in both men (13.9% in 1986; 31.6% in 1991) and women (3.2%
in 1986; 19.0% in 1991). After controlling for a variety of factors th
at might affect use of thrombolytic agents, younger age, absence of a
history of either congestive heart failure or stroke, and experiencing
a Q-wave AMI were associated with receipt of thrombolytic therapy in
both men and women; having an anterior AMI also was associated with us
e of thrombolytic agents in men. Women without as compared with those
with a history of angina pectoris were significantly more likely to re
ceive thrombolytics. Men who had Medicare insurance were significantly
less likely to receive thrombolytics than were men with other types o
f health insurance. When this analysis was restricted to patients who
were seen in area-wide hospitals within 6 hours of the onset of sympto
ms suggestive of AMI, similar factors were associated with the receipt
of thrombolytic agents in men and women. The results of this communit
y-wide study suggest a marked increase over the 5-year study period in
the use of thrombolytic therapy in both men and women, with a greater
relative increase observed in women. A relatively similar profile of
patients likely to receive thrombolytic therapy was seen in both men a
nd women.
