Heart Attack Can Differ in Women and Men
More Heart Attacks Still Missed in Women Than Men, Researchers Say
Jan. 18, 2005 -- Heart attacks are still more likely to go undiagnosed in
women than men, putting women at risk of not receiving the treatment they need
for heart disease.
The charge, made in a British study in the February issue of the journal
Heart, is the latest in a long line of studies that indicate women
don't always get the heart attack attention they deserve.
"It has been repeatedly shown that women diagnosed as having had a
[heart attack] tend to be managed less aggressively and have a poorer prognosis
compared to men," write the researchers, who included clinical biochemist
Efforts have been made to correct that. For years, experts have preached
that women should take their heart attack risk seriously and that women's
symptoms may differ from those seen in men.
For both men and women, heart attack symptoms can include:
- Squeezing chest pain or pressure
- Shortness of breath
- Tightness in chest
- Pain spreading to shoulders, neck, arm, or jaw
- Feeling of heartburn or indigestion with or without nausea and
- Sudden dizziness or brief loss of consciousness
Heart attack symptoms that are more likely in women include:
- Indigestion or gas-like pain
- Dizziness or nausea
- Unexplained weakness or fatigue
- Discomfort or pain between the shoulder blades
- Recurring chest discomfort
- Sense of impending doom
Blood Test Important
Kilpatrick blows the whistle on his own employer, England's Hull and East
Yorkshire Hospitals. Kilpatrick and S.A. Madrid Willingham studied heart attack
diagnoses at the hospital in 2002.
Data came from 2,500 men and 2,300 women. First, patients were tested for a
chemical called cardiac troponin T.
High levels of troponin are sufficient to diagnose heart attacks, according
to standards set by the European Society of Cardiology and the American College
of Cardiology in 2000.
Next, the researchers checked the diagnoses given to the patients when they
were discharged from the hospital. The diagnoses didn't always jive with the
A total of 561 heart attacks were diagnosed. In 93% of those cases, the
patients had high troponin levels.
But many other people with high troponin levels didn't get a heart attack
diagnosis. Only 40% of the patients with high troponin levels were diagnosed
with a heart attack.
Whereas 46% of men with elevated troponin were given a heart attack
diagnosis, only 33% of such women were deemed to have had a heart attack.
Women seem less likely to be diagnosed with a heart attack despite raised
troponin being a reliable test, say the researchers.
"This lack of systematic use of new criteria appears to disadvantage
females more than males," they conclude.
