Women Die More From Heart Attacks Than Men -- Unless the ER Doc Is Female (scientificamerican.com)

Women who suffer from heart attacks may be at a higher risk of death in the emergency room if they see a male physician rather than a female one, a new study suggests. The study doesn't jump to conclusions, but doctors and cardiologists have a few theories. There could be a systematic bias where male physicians are not listening to female patients' complaints as readily as [those of] a man, or there could be a bias that favors men in the medical literature, leading to misdiagnoses in women. It may also be that female doctors do a better job than their male counterparts. "In the new study everyone was more likely to survive if they saw a female physician, and a study published last year [...] indicated all patients of female physicians had lower mortality and hospital readmission rates," reports Scientific American. From the report: Heart disease is the number-one killer of both men and women, but the latter are significantly less likely to survive heart attacks. According to 2016 American Heart Association statement, 26 percent of women will die within a year of a heart attack compared with just 19 percent of men. The gap widens with time: By five years after a heart attack almost half of women die, compared with 36 percent of men. The reason has eluded researchers for years, but the authors of the new study point to the disparity in male and female representation in emergency doctors as a potential source of answers. The researchers analyzed a Florida Agency for Health Care Administration database containing every heart attack case from every ER in the state (excluding Veterans Affairs hospitals) between 1991 and 2010.

The researchers divided 500,000-plus cases into four categories: male doctors treating men; male doctors treating women; female doctors treating men; and female doctors treating women. "All of those are statistically indistinguishable except for male doctor -- female patient," says Brad Greenwood, an author on the study and a data scientist at the University of Minnesota. If a heart attack patient is a woman and her emergency physician is a man, he says, her risk of death suddenly rises by about 12 percent. Put another way, a heart attack patient dies in the ER about 11.9 percent of the time overall -- but the research team found women with heart attacks will die about 12.4 percent of the time if their cases are handled by male doctors. This means approximately one out of every 66 women with heart attacks dies in the emergency room if she sees a male doctor rather than a female one.

      I'm not sure that's the cause. The study also shows that male doctors with more experience with female patients have a better outcome than male doctors with less experience with female patients.
      There are things women and men might lie about or unconsciously "adjust" in different ways. If you had a non-obese patient, the male might claim he weighs a little more than he does, and a woman might claim she weighs a little less than she does. But in a hospital setting, I'm sure they do actual measurements instead of relying on the patient.

      But you may have touched upon a potential factor here: communication. It may be, for example, that female patients are less good at volunteering the important information, and that female doctors and male doctors with experience treating females have less problems communicating in a way where the female patient tells important things. Which may include things that a female patient may be uncomfortable disclosing to a young male, like also having an UTI, yeast infection, irregular periods or copper implant. And a younger male doctor may be more uncomfortable with and less good at getting this information, perhaps expecting "any other problems?" to cover that. A doctor that's experienced with either being a women or treating female patients may just be better at asking direct questions.

Only roughly 1/3 of CPR patients survive.

    Myocardial Infarctions are tissue death in the heart, caused by a blockage. They're typically painful because muscle tissue in the heart is _dying_. Many people have survived numerous small infarctions. ECG's, however, electro cardiograms, where electrodes are placed on the chest and a few elsewhere on the body to monitor heart activity, does involve at least opening up the shirt and exposing the chest.

    Also, many patients are quite frightened in the emergency room. I can easily picture a frightened, older female patient, who grew up more than 50 years ago, being less frightened and less reluctant to share their full medical information with a male physician, and their family or caregivers less able to communicate with a male physician.

The truth is we have sets of characteristics we tend to lump under race categories and people just go along with what everyone around them has said when they grew up.

    Legally your race is defined by self-identification because we have no way to define it. Right now we play so fast and loose with that word that it is meaningless. There are certain medical factors that go along with genetic race but the utility of considering that is no different than screening for any of the millions of genetic illnesses that don't have a high correlation to racial identification. The DNA ancestry and culture angle is highly in congruent with the way most are defining these things. For example here in the states everyone who is black is treated like a former slave and those who are former slaves are that this point genetically as much or more like their slave owner ancestors than their slave ancestors and you can't from a genetic standpoint claim one more than the other. Almost every disadvantage associated with being one of them that can actually objectively be proven can be solved in a single generation by moving outside of neighborhoods that group others with the same label together, integrating with general american culture, and hard work. In other words, those problems have to do with neighborhoods and cultures and not genetic history.
