- About 17.9 million all over the world passed away in 2019 from heart disease, with 85% of those deaths credited to stroke and cardiac arrest.
- While non-modifiable aspects such as family history can impact an individual’s danger of establishing heart disease. There are likewise flexible danger aspects, consisting of smoking cigarettes, high blood pressure, high cholesterol, and weight problems.
- Researchers from the University of Copenhagen in Denmark have actually discovered individuals without recognized heart disease that have undiscovered obstructive coronary atherosclerosis increase their danger for a cardiac arrest eightfold.
- Their findings recommend that almost half of all grownups over 40 might have “hidden” heart disease that go undiscovered.
In 2019, about

The research study appears in the Annals of Internal Medicine, a journal of the American College of Physicians.
Coronary atherosclerosis — likewise referred to as coronary artery illness — takes place when plaque from cholesterol deposits develops inside the arteries that bring blood to the heart.
This plaque accumulation narrows the arteries, making it harder for
Symptoms of coronary atherosclerosis might consist of:
- pressure, squeezing, or discomfort in the chest
- shortness of breath
- light-headedness
- queasiness
- heartburn and/or indigestion
Although there is no remedy for coronary artery illness, the condition can be handled through
Coronary atherosclerosis is the
Symptoms of a cardiac arrest consist of:
Heart attack signs might begin really rapidly or last for a couple of days. The quicker an individual gets treatment for a cardiac arrest, the much better their
According to Dr. Klaus Fuglsang Kofoed, medical associate teacher in the Department of Clinical Medicine at the University of Copenhagen in Denmark and matching author of this research study, the research study group chose to study how coronary atherosclerosis effects an individual’s danger for a cardiac arrest due to the fact that it is the illness procedure accountable for cardiac arrest and heart death.
“It may develop many years before an individual has any symptoms,” Dr. Kofoed informed Medical News Today. “To prevent heart attack, it is therefore very important to understand what characteristics define an asymptomatic individual at elevated risk of clinically manifested diseases.”
In this research study, Dr. Kofoed and his group analyzed over 9,500 individuals aged 40 or over who had no recognized signs of heart disease. Study individuals were evaluated utilizing
Upon analysis, scientists discovered 54% of the research study individuals had no noticeable coronary atherosclerosis.
Of the staying 46% that were discovered to have formerly undiscovered coronary atherosclerosis, 36% of individuals had nonobstructive illness, and 10% had obstructive illness.
Additionally, researchers discovered amongst individuals identified with formerly undiscovered coronary atherosclerosis, 61% were males, and 36% were women.
“The greatest surprise was that as high as 10% had obstructive diseases yet without having symptoms.
[This is] a very important observation which we will explore further in additional analysis.”

MNT likewise consulted with Dr. Rigved Tadwalkar, a board accredited cardiologist at Providence Saint John’s Health Center in Santa Monica, CA, about this research study.
Dr. Tadwalkar said this is an interesting research study due to the fact that it resolves an essential concern in cardiology — what is the significance of coronary artery illness in the asymptomatic individual?
“Thus far, our understanding about the significance of coronary artery disease comes mostly from those who have clinical symptoms of the disease and have undergone
“It was eye-opening to see that among people with no symptoms, subclinical atherosclerosis may be found in more than 50% of men and nearly one-third of women,” he included. “Similarly striking was the discovery that 10% of this study population had obstructive coronary disease.”
Dr. Tadwalkar likewise commented that the outcomes of this research study are of high worth in figuring out an asymptomatic individual’s danger for a cardiovascular occasion.
“The use of CT coronary angiography in the preventative setting would allow us to establish whether coronary artery disease truly exists, which is a question that we are often not able to definitively answer for patients under current guideline-based practice,” he continued. “Based on the results of the CT coronary angiogram, we should now be able to better determine whether an asymptomatic person is at a higher risk of having a heart attack or dying.”
“This is informative in helping us craft appropriate preventative strategies so that people deemed to be at higher risk have a much better chance of not succumbing to a cardiovascular event,” Dr. Tadwalkar included.
