ATLANTA (CNN) – According to a new study, the risk of heart attack in young women seems to be increasing and researchers are trying to figure out why. The total proportion of hospital stays related to heart attacks in the United States, which is due to young patients aged 35 to 54 years, has steadily increased from 27 percent in 1995.
-99 to 32 percent in 2010-2014, with the largest increase observed in young women. The study was recently published in the journal Circulation.
During these periods, the number of registrations of young women increased from 21 to 31 percent, compared with 30 to 33 percent in young men.
"The message to take away is that a growing percentage of heart attacks occur in younger patients, even though our population is getting older, and the biggest increase seems to be in young women," said Melissa Caughey, senior author of St. udy and a research instructor in the Department of Cardiology at the School of Medicine at the University of North Carolina at Chapel Hill.
A heart attack or an acute myocardial infarction occurs when part of the heart does not receive enough blood. According to the United States Centers for Disease Control and Prevention, about 790,000 Americans suffer a heart attack each year. Heart attacks are most common as a result of heart disease ̵
Worldwide, according to World Health, 85 percent of all cardiovascular deaths are due to heart attacks and strokes.
The new study included data on 28,732 hospital admissions to heart attack in patients aged 35-74 between 1995 and 2014.
The data came from the Atherosclerosis Risk in Communities Study (ARIC) and hospital admissions were in four communities: Forsyth County , North Carolina; Washington County, Maryland; Jackson, Mississippi; and eight northwestern suburbs of Minneapolis.
Researchers looked at young patients aged 35 to 54, who accounted for 30 percent of hospitalizations.
In this group, the annual incidence of heart attack hospitalization increased from 1995 to 2014 in young men, but a rise was observed in young women, the researchers found.
"When we examined the incidence – this means the number of patients who had a heart attack every year, divided by the total population of patients in the group – we have seen that the incidence in young men has actually declined, and this Kind of parallels to what we see in the older populations, but we have seen that there is a slight increase for the young women, "Caughey said. 19659002] "That was surprising, because it goes against the other trends in other demographic groups," she said. "There were earlier studies from the same ARIC surveillance that showed a decline, and they were mostly elderly populations or elderly patients … The national trends also show the same that the incidence of heart attacks is decreasing"
Compared with young men in the study, the young women were more likely to have health insurance and a history of high blood pressure, diabetes, chronic kidney disease and stroke, the researchers found. The young women were also more often black and smoked less often.
The November online study revealed some limitations, including data from only four communities. To determine whether similar tendencies would develop nationwide, further research is needed.
In addition, the data was limited to medical records and did not contain information about obesity, a known risk factor for a heart attack.
"When I saw the high rates of diabetes among women, I thought," What about obesity? "The study had no information on whether these women were obese or not," Dr. Nieca Goldberg, cardiologist and medical director of the Joan H. Tisch Center for Women's Health at New York's Langone Health in New York who was not involved in the study.
Such risk factors – including type 2 diabetes and high blood pressure – may explain why young women have an increase in heart attacks, but more research is needed to find out what could drive this increase, added Goldberg.
"It's complex – are the risk factors and symptoms recognized by the vendors – are the patients, despite being insured, taking the time to make an appointment, was it difficult to get an appointment?" You just gave up? "Asked Goldberg."
"It's possible, but look at some other behaviors in this age group. People work and spend more time at their desks than before and are not physically active. Lack of physical activity is also a risk factor, "she said." Sleep deprivation and increased stress increase blood pressure; this is also a risk factor. "
The study's findings are" particularly conspicuous as populations age, and yet a higher proportion of heart attack patients are young patients, "said Dr. Harmony Reynolds, co-director of Sarah Ross Soter Center for Women's Cardiovascular Research and Associate Professor of Medicine at the NYU School of Medicine, New York.
This is likely related to risk factors that have become more common in heart attack patients, such as diabetes and high blood pressure, said Reynolds, who was not involved in the study.
"We especially see [increase] in young women and especially in young African Americans." "Women," Reynolds added.
In addition, women were less likely to receive certain types of therapy, such as: These include drugs that lower cholesterol and prevent blood clotting. Although higher mortality rates were found in women with heart attacks in earlier studies, the risk of death for some reason at one year was similar for women to men.
Reynolds said many people are unaware of their risk factors for a heart attack and must proactively talk with their doctors about how to reduce their risk. Many may also be unaware that heart attacks may look different in women who are more likely to experience atypical symptoms such as nausea or sweating, she added.
Another study published in the journal Circulation last year found this in adults. In younger women, lesser-known acute myocardial infarction symptoms than chest pain were more common than in men, and more than half of the physicians who saw women looking for these symptoms did not realize that the symptoms were cardiac.
Some of these heart attack symptoms may include shortness of breath; Dizziness; or the feeling of pain or discomfort in one or both arms, the back, neck, jaw or stomach, according to the American Heart Association.
"Some people believe that having a heart attack will make them look like they are in the movies – people will cling to their breasts, lie down on the ground and feel horrible – and for some people that's a lot more subtle, "said Reynolds. "I saw someone last week who had a heart attack in their two front teeth."
