<p>Highly active individuals with elevated coronary artery calcium (CAC) levels did not experience an increased risk for mortality from those high activity levels, new <a href="https://jamanetwork.com/journals/jamacardiology/fullarticle/2722746?guestAccessKey=3c09c9c9-2972-4158-a259-62acd9f7c23c">study</a> results from the Cooper Center Longitudinal Study suggest.<p>The observational study included 21,758 men without prevalent cardiovascular disease and with varying levels of <a href="https://proddocwire.wpengine.com/cardiology/incentive-program-leads-to-increased-physical-activity-in-patients-with-ischemic-heart-disease/">physical activity</a>. Self-reported physical activity was categorized into groups according to metabolic equivalent task (MET)-minutes per week (at least 3,000 MET-min/wk: n=1,561; 1,000 to 2,999 MET-min/wk: n=3,750; and less than 1,500 MET-min/wk: n=16,477), with CAC scores categorized into 2 groups of either at least 100 (n=5,314) and less than 100 (n=16,444) Agatston Units (AU). The primary study outcomes were all-cause and <a href="https://proddocwire.wpengine.com/tag/cardiovascular/">cardiovascular</a> disease(CVD) <a href="https://proddocwire.wpengine.com/cardiology/study-higher-work-stress-linked-with-elevated-morality-risk/">mortality</a>.</p><p>According to the results, men with at least 3,000 MET-mins/wk were more likely to have CAC of at least 100 AU compared to those with less physical activity. Those with CAC scores less than 100 AU and physical activity of less than 3,000 MET-mins/wk were half as likely to die as those with less than 1,500 MET-min/wk (HR=0.52; 95% CI, 0.29 to 0.91). There was no significant increase in all-cause mortality in the most active group. In the least active group, those with CAC scores of at least 100 AU were twice as likely to die from CVD compared to those with scores of less than 100 AU (HR=1.93; 95% CI, 1.34 to 2.78).</p><p>&ldquo;In highly active individuals with elevated levels of coronary artery calcification, it appears that there is no evidence to suggest increased mortality risk from high levels of <a href="https://proddocwire.wpengine.com/docwire-pick/exercise-not-beneficial-for-all-aspects-of-fibromyalgia-in-women/">physical activity</a>,&rdquo; the researchers wrote in their study.</p><blockquote class="twitter-tweet" data-width="500" data-dnt="true">

<p lang="en" dir="ltr">Just out, coronary calcium scores are higher and do not predict worse outcome in highly active individuals.   Meaning peak VO2 is a more accurate predictor of long-term outcomes than coronary calcium score:  <a href="https://t.co/U3uQx3hNan">https://t.co/U3uQx3hNan</a></p>
