Increased risk of atrial fibrillation among elderly Norwegian men with a history of long-term endurance sport practice |
Cross-country skiing |
|
|
|
|
Lifelong physical activity regardless of dose is not associated with myocardial fibrosis |
Participants in competitions organized by the US Masters Sports Associations (marathons and triathlons) |
|
-
Left ventricular end-diastolic volume, end-systolic volume, and mass were higher in those with a history of higher physical activity levels.
-
No difference in ejection fraction.
-
No intergroup difference in late gadolinium enhancement (indicating no evidence of myocardial fibrosis in the participants).

Cardiovascular risk and disease among masters endurance athletes: insights from the Boston MASTER (Masters Athletes Survey To Evaluate Risk) initiative |
Boston Marathon Runners |
|
-
64% of athletes had one or more Cardiovascular risk factors;
-
9% prevalence of established cardiovascular disease;
-
AF was associated with years of exposure to exercise;
-
CAD was associated with dyslipidemia;
-
CAD was not associated with exposure to exercise.
|
|
|
Prevalence of subclinical coronary artery disease in masters endurance athletes with a low atherosclerotic risk profile |
Running and cycling |
|
-
Most athletes (60%) and control subjects (63%) had normal CAC scores.
-
Number of years of training was the only independent variable associated with a higher risk of CAC.
-
Male athletes were more likely to have coronary plaques compared with sedentary men with a similar.

Assessment of cardiovascular risk and preparticipation screening protocols in masters athletes: the Masters Athlete Screening Study (MASS): a cross sectional study |
23 disciplines, primarily running, cycling, hockey, triathlon and rowing |
|
-
Cardiovascular disease was detected in 11.4%, with CAD (7.9%) being the most common diagnosis.
-
A high Framingham risk score (>20%) was observed in 8.5% of the study population.
-
Ten athletes were diagnosed with significant CAD;
-
90% were asymptomatic. A high Framingham risk score was the strongest indicator of underlying CAD.

ECG criteria for the detection of high-risk cardiovascular conditions in master athletes |
Athletes linked to the Dutch Olympic Committee |
-
2578 athletes;
-
> 35 years old
|
-
Atrial enlargement (n = 109; 4.1%) and left ventricular hypertrophy (n = 98; 3.8%) were the most common abnormalities identified using the ESC-2005 or Seattle criteria.
-
ST-segment deviation (n = 66; 2.6%) and T-wave inversion (n = 58; 2.2%) were the most frequent findings based on the International criteria.
-
The ESC-2005 criteria detected a larger number of exercise-related heart conditions (n = 46; 1.8%) compared with the Seattle (n = 36; 1.4%) and International criteria (n = 33; 1.3%).
-
Coronary artery disease was the most frequently identified high-risk cardiovascular condition (n = 24; 0.9%).

The acute effects of an ultramarathon on biventricular function and ventricular arrhythmias in master athletes |
Ultramarathon |
-
68 athletes (47% men);
-
> 40 years old
|
-
Increased R wave amplitude in V1 and prolonged QTc interval following the ultramarathon.
-
7% of athletes exhibited isolated exercise-induced premature ventricular beats.
-
No episodes of nonsustained ventricular tachycardia or changes in left ventricular ejection fraction, global longitudinal deformation, or torsion were observed.

|
Physical activity, coronary artery calcium, and cardiovascular outcomes in the Multi-Ethnic Study of Atherosclerosis (MESA) |
Physical activity |
-
6777 men and women;
-
45 to 84 years old
|
-
Participants at low risk for CAC in the highest PA quartile had reduced adjusted hazard ratios for CVD and all-cause mortality compared to those in the lowest PA quartile.
-
Participants at high risk for CAC in the highest PA quartile also had reduced adjusted hazard ratios for all-cause mortality compared to those in the lowest PA quartile.
-
High PA was not associated with an increased risk of any outcomes, regardless of CAC category, sex, or race/ethnicity.
|
|
|
Associations of long-term physical activity trajectories with coronary artery calcium progression and cardiovascular disease events: results from the CARDIA study |
Physical activity |
|
-
The High PA group had a greater risk of CAC progression compared to the low PA group after adjusting for traditional cardiovascular risk factors.
-
High PA was not associated with an increased risk of incident cardiovascular events, and the incidence of cardiovascular events among participants with CAC progression was similar across all physical activity levels.

Lifelong endurance exercise and its relation with coronary atherosclerosis |
Running, cycling, triathlon |
|
-
Prevalence of coronary plaques (calcified, mixed, and non-calcified).
-
The athlete group demonstrated higher peak oxygen consumption.
-
Lifetime endurance sports participation was associated with greater odds of having ≥1 coronary plaque (OR: 1.86, CI: 1.17–2.94), ≥1 proximal plaque (OR: 1.96, CI: 1.24–3.11), ≥1 calcified plaque (OR: 1.58, CI: 1.01–2.49), ≥1 proximal calcified plaque (OR: 2.07, CI: 1.28–3.35), ≥1 non-calcified plaque (OR: 1.95, CI: 1.12–3.40), ≥1 proximal non-calcified plaque (OR: 2.80, CI: 1.39–5.65), and ≥1 mixed plaque (OR: 1.78, CI: 1.06–2.99) compared to healthy non-athletes.
