Whereas excessive ldl cholesterol, hypertension, diabetes and smoking are well-known coronary heart illness dangers, not everybody who has a coronary heart assault has them. Actually, earlier analysis has proven that 14% to 27% of coronary heart assault sufferers have none of those threat elements.

Now, a brand new research from researchers at Intermountain Well being in Salt Lake Metropolis finds that these sufferers had one factor in frequent: all of them tended to have excessive ranges of coronary calcium.

Outcomes of the brand new Intermountain research present that scans that detect this type of plaque buildup ought to be thought-about as a part of their commonplace care, even within the absence of the 4 commonplace modifiable threat elements, in order that these sufferers could be recognized and handled earlier than their first coronary heart assault occasion happens.

“Measuring coronary calcium could have a major impact on how we identify who is at risk for heart disease,” stated Jeffrey L. Anderson, lead writer of the research and analysis doctor at Intermountain Well being. “We need to go beyond just the four major modifiable risk factors because there are risk factors we don’t yet recognize or understand about what’s causing increased risk of heart attack in these patients.”

Findings from the research had been introduced on the American Coronary heart Affiliation’s Scientific Classes 2023 in Philadelphia on Nov 11, 2023.

Within the research, Intermountain researchers recognized 429 coronary heart assault sufferers who additionally had coronary artery calcium scans. Of these, 369 had commonplace modifiable threat elements (SMuRF), like a prognosis or remedy of hypertension, hyperlipidemia, diabetes, and or smoking; and 60 didn’t (SMuRF-less).

Researchers examined these sufferers’ calcium artery scan scores, after which additionally main hostile cardiovascular occasions, like one other coronary heart assault, stroke, or loss of life, at 60-days and long run.

Researchers discovered that SMuRF-less sufferers had excessive charges of, and better percentile of, coronary calcium scores. In addition they discovered that 77% of those sufferers met their standards for preventative remedy, like statins and/or aspirin. Sufferers with SMuRF, as anticipated, additionally had excessive CAC scores and percentiles. Outcomes had been extra favorable total for SMuRF-less sufferers and for these sufferers with decrease coronary artery calcium scores.

Whereas coronary artery calcium scans have gotten extra frequent and reasonably priced, they’re nonetheless not a part of guideline-directed commonplace of care.

“We’re missing about a quarter of people who are at risk for heart attack events because we’re still relying on just the standard risk factors,” stated Dr. Anderson. “We haven’t been doing scans in low-risk patients that don’t have these common risk factorsbut that may need to change given our findings, so that we can identify these seemingly low-risk patients who care not, and provide preventive therapy.”
