Dangerous Paradox: Physical Activity May Hasten Build-Up of Heart Attack Risk Factor

” Increasing rates of coronary artery calcification is a phenomenon that is observed both in reaction to reliable treatment like statin therapy and workout.

The findings do not outweigh the numerous health benefits of workout, stress the researchers..
The coronary artery calcium rating, or CAC score for short, is utilized to guide treatment to fend off a heart attack or stroke. Statins are suggested for the majority of individuals with a CAC rating of 100 or above.
Regular exercise is connected with a dose-dependent reduction in the threat of weight problems, diabetes, heart attack/stroke, and death, to name a few things..
The research reveals that despite these important health advantages individuals who are extremely physically active seem to have high levels of calcium deposits in their coronary arteries. So its unclear if workout might itself be associated with calcification (artery hardening).
In a quote to explore this further, the researchers studied healthy adults who went through routine detailed check-ups at two significant university hospital in Seoul and Suwon, South Korea, in between March 2011 and December 2017, as part of the Kangbuk Samsung Health Study..
At each health check, participants submitted a questionnaire, which included questions on medical and family history, way of life, and academic attainment. Weight (BMI), high blood pressure, and blood fats were likewise examined.
Physical activity was officially classified at the very first check-up as either inactive, reasonably active, or health-enhancing (extremely) physically active, using a verified questionnaire..
Scans tracked the advancement and/or development of coronary artery calcification which was then scored (CAC rating) over an average duration of 3 years.
Some 25,485 people (22,741 men and 2744 ladies), aged a minimum of 30, and with a minimum of two CAC scores, were included in the last analysis.
Some 47% (11,920), 38% (9683 ), and 15% (3882) of them were, respectively, non-active, reasonably active, and intensely physically active– comparable to running 6.5 km/day..
Those who were more physically active tended to be older and less likely to smoke than less physically active individuals. They also had lower total cholesterol, more hypertension, and existing evidence of calcium deposits in their coronary arteries.
A graded association between physical activity level and the prevalence and progression of coronary artery calcification emerged over time, regardless of CAC scores at the start of the monitoring duration.
The estimated changed typical CAC ratings in all 3 groups at the start of the tracking period were 9.45, 10.20, and 12.04, respectively..
Greater physical activity was associated with faster progression of CAC ratings both in those with no calcium deposits and in those who currently had a CAC score at the start of the monitoring period.
Compared with those who were non-active, the estimated changed 5-year typical boosts in CAC scores in reasonably and extremely active individuals were 3.20 and 8.16, respectively, even after representing potentially prominent factors, consisting of BMI, blood pressure, and blood fats.
This is an observational research study, and as such, cant establish cause. The scientists likewise acknowledge several research study constraints, including the lack of an unbiased assessment of physical activity; and no information on occurrence heart attacks/stroke or on CAC density or volume..
Exercise might increase coronary atherosclerosis (artery constricting) through mechanical tension and vessel wall injury and through the physiological reactions it triggers, such as boosts in high blood pressure and parathyroid hormonal agent, they explain. Physical activity might also modify the impact of diet plan, vitamins, and minerals, they suggest.
” The second possibility is that physical activity might increase CAC scores without increasing [cardiovascular disease] danger,” they compose.
” The cardiovascular benefits of exercise are unquestionable,” they highlight, reiterating nationwide standards suggesting a minimum of 150– 300 minutes/week of moderate strength or 75– 150 minutes/week of energetic intensity aerobic physical activity.
” Patients and doctors, however, need to think about that engaging in physical activity may speed up the development of coronary calcium, perhaps due to plaque recovery, calcification and stabilization,” they conclude.
In a linked editorial, Drs Gaurav Gulsin and Alastair James Moss, of the Department of Cardiovascular Science, University of Leicester, ask: “Do these findings indicate that we should stop utilizing coronary artery calcium scores to examine coronary artery disease?”.
The research study highlights the intricacy of analyzing CAC ratings in patients who have actually upped their physical activity or began taking statins– also related to higher ratings, they point out..
” While advocates would argue that it is an efficient tool to screen for subclinical atherosclerosis in asymptomatic individuals, clinicians must be careful regarding the overuse of this test in otherwise healthy individuals,” they warn.
In a connected podcast, Dr. Moss discusses that non-calcified plaque, which is more unstable and most likely to burst, might be more vital and need to be scored to assess an individuals future threat of a heart attack or stroke.
” It might be the target we require to search for is non-calcified plaque instead of calcified plaque,” he suggests. This wasnt visible on the scans used in this research study.
” Increasing rates of coronary artery calcification is a phenomenon that is observed both in reaction to reliable treatment like statin therapy and workout.
He repeats: “Clearly, workout is one of the finest ways of trying to manage cardiovascular danger in [ individuals without signs]”.
