Is there anything new regarding its use in risk assessing for adverse events? I think there is. [ Music ] Hi, Dr. Bernie here, and welcome to Practice Impact Extra. Cardiovascular disease increases markedly and is a leading cause of death in older individuals.
Coronary calcium scores predict clinical risk in both younger and older patient population. And there is a growing interest in using coronary artery calcification scanning to identify older patients at increased risk, to identify the possibility of practical lifestyle interventions to change their risks. A study published in the Mayo Clinic Proceedings in June of 2020 had in its objective to assess with a self-reported physical activity, characterized either low, moderate, or high, reduce the mortality risks associated with coronary plaque burden measured by CAC score.
There was this track, more than 2,300 patients between the ages of 65 to 84 who had calcium scoring between 1998 and 2016. The average age of the patient was 70 years of age, and they were followed for 10.6 years. So what did they find? 533 patients died. That's 23%. That became an annualized mortality of 2.3%. So the first result.
They noted the highest mortality, 2.9% per year, was noted on patients who reported low physical activity. And the lowest mortality, 1.7%, was in patients who had reported high physical activity. Among patients with low coronary scores, the survival was similar for all physical activities. The low score, physical activity did not impact. The all-cause mortality, however, jumped significantly in patients who had moderate calcium score and low activity and was particularly high for people who had a score greater than 400 with an overall all-cause mortality of 2.4-fold increase for patients in the low physical activity group.
So what's the clinical significance? A simple assessment of daily physical activity likely can improve the effectiveness of calcium artery scoring and scanning for risk stratification in older patients. Other studies have provided evidence that physical activity in middle and older individuals really can improve vascular function, prevent, or restore age-related decline in endothelial function.
It seems to me it would make a lot of sense to conduct a prospective study to assess the clinical benefits of exercise programs in older patients who have substantial atherosclerosis on coronary artery calcium scanning.
