During these periods, there was an increase in these admissions from 21% to 31% among young women, against 30% to 33% among young men, showed the study.
Risk Factors for Heart Attack
The new study included 28,732 hospitalizations for heart attack in patients aged 35 to 74 between 1995 and 2014.
The researchers looked closely at young patients aged 35 to 54, who accounted for 30% of hospitalizations.
In this group, the annual incidence of hospitalizations for heart attack decreased from 1995 to 2014 among young men, but an increase was observed among young women, the researchers found.
"When we looked at the incidence – that is, the number of patients having a heart attack each year, divided by the total patient population in the group – we found that there was actually had a decrease in incidence among young men and that sort of matches what we see in older populations, but we found a slight increase for young women, "said Caughey.
"It was surprising because it goes against other trends in other demographic groups," she said. "Earlier studies of the same ARIC surveillance system showed a decline and it was mostly about older populations or older patients … National trends also show the same thing, ie there is a decrease in the number of heart attacks. "
Compared to young men in the study, young women were more likely to have medical insurance and a history of hypertension, diabetes, chronic kidney disease and stroke, the researchers found. Young women were also more likely to be black and less likely to smoke.
Such risk factors – such as type 2 diabetes and high blood pressure – may help to explain the increase in heart attacks in young women, but more research is needed to determine precisely what could lead to this increase, added Goldberg.
"It is complex." Are risk factors and symptoms recognized by providers and patients, even though they have insurance, take the time to make an appointment? difficult to get an appointment so they just gave up? " Goldberg asked.
"It's possible, but observe other behaviors of this age group." People are working and spending more time than before at their desks and are not physically active. Physical activity is also a risk factor, "she said. "Lack of sleep and increased stress increase blood pressure, it is also a risk factor."
Unusual heart symptoms in women
This is probably related to risk factors that have also become increasingly common in patients with heart attacks, such as diabetes and high blood pressure, said Reynolds, who did not participate at the study.
"We particularly see that [increase] among young women and especially young African-American women, "Reynolds added.
In addition, women were less likely to follow certain types of treatments, such as cholesterol-lowering drugs and prevent clotting. However, despite previous research that found higher mortality rates among women with heart attacks, the risk of all-cause death after one year was comparable between men and women.
Reynolds said many people are unaware of their risk factors for heart attack and need to be proactive in talking to their doctors about how to reduce their risk. Many may not be aware that heart attacks may look different in women, who are more likely to have atypical symptoms such as nausea or sweating, she added.
"Some people expect the heart attack to look like what you see in the movies – as if people were grabbing their chest and lying on the floor for to feel horrible – and for some people, it's much more subtle than that, "Reynolds said. "I saw someone last week who felt a heart attack in his two front teeth."
