Within about 3.5 many years, 193 people today concerned with the study had died and 71 experienced seasoned coronary heart attacks. 

Fox News Electronic achieved out to the research authors for remark.

Dr. Adedapo Iluyomade, a preventive cardiologist at Baptist Wellbeing Miami Cardiac & Vascular Institute in South Florida, was not associated in the analyze but reviewed the findings.

“This examine supports the relevance of focusing on early prevention and early identification of individuals who would be regarded significant-danger for long term cardiovascular activities,” he advised Fox News Digital in an interview.

“There are some danger variables, these kinds of as genetics, environmental factors and serious swelling, that just cannot be effortlessly plugged into a threat calculator or assessment resource,” he claimed.

In the study, doctors used angiograms, which are medical images that show the inside of the heart, to determine participants' heart health.

“Coronary atherosclerosis often develops in the absence of signs for the reason that the fundamental hazard things, these types of as higher blood pressure and significant cholesterol, ordinarily do not result in indicators possibly,” said Dr. Jim Liu, a cardiologist at The Ohio Point out University Wexner Medical Center. He was not included in the examine.

Doctor phone calls for preventive screenings

Dr. Iluyomade is hopeful that growing the availability of heart health and fitness screenings for men and women devoid of indications could assistance help you save lives.

In unique, he recommends rolling out calcium-score screening heart exams, which use computerized tomography (CT) to detect any plaque buildup in the arteries.

Insurance typically does not protect a CT calcium examination the cost is generally concerning $100 and $400, according to Healthline.

A different screening option is CT angiography, which was used in the Copenhagen University analyze. This test consists of injecting dye into the individual using an IV and then getting photographs of blood vessels to detect any potential blockages.

"It’s important for patients to see their health care providers routinely to make sure risk factors are addressed," a cardiologist told Fox News Digital.
