Cardiovascular disease is an important cause of disability in activities of daily living (ADL) through its effect on physical functioning. However, it is unclear whether subclinical vascular abnormalities and rate of change in subclinical vascular abnormalities is also associated with an impaired physical ability and with ADL disability. In a longitudinal study, 490 middle-aged and older persons were included. Physical ability was measured using the Short Physical Performance Battery and ADL disability using a questionnaire on self-reported basic and instrumental ADL. Subclinical vascular abnormalities were measured by pulse wave velocity (PWV) and carotid intima media thickness (CIMT, in men only). Longitudinal associations between baseline markers of subclinical vascular abnormalities, their rate of change, and change in physical ability or ADL disability were assessed using generalized estimation equation models. After adjustment for confounders, higher baseline PWV, change in PWV, baseline CIMT (in men) and change in CIMT (in men) were associated with a higher rate of change in physical ability (regression coefficients 0.035, 95% CI [0.018; 0.052]; 0.047, 95% CI [0.024; 0.069]; 0.214, 95% CI [0.070; 0.358] and 0.148, 95% CI [0.019; 0.277], respectively). No relations were found for change in ADL disability. In subjects with incident cardiovascular disease, higher change in PWV was associated with a higher rate of change in ADL disability (regression coefficient 0.054, 95% CI [0.001; 0.106]). The present study showed that subclinical vascular abnormalities and rate of change were associated with higher rate of change in physical ability. The association between (change in) subclinical vascular abnormalities and ADL disability tended to be stronger in persons with incident and prevalent cardiovascular disease. These data may suggest that ADL decline is more a direct effect of experienced clinically manifest vascular events rather than the effect of progression of subclinical vascular abnormalities.

Living independently is an important component of quality of life. Cardiovascular diseases are prominent among the chronic conditions that predispose elderly people to functional limitations and disability, which impair quality of life. Insight into factors that play a role in the development process of limitations and disability of patients with subclinical cardiovascular diseases will aid in the development of preventive interventions. The aim of this study was to investigate the association of vascular status with muscle strength and physical functioning in middle aged and elderly men.

Introduction: The optimal pre-participation screening strategy to identify athletes at risk for exercise-induced cardiovascular events is unknown. We therefore aimed to compare the American College of Sports Medicine (ACSM) and European Society of Cardiology (ESC) pre-participation screening strategies against extensive cardiovascular evaluations in identifying high-risk individuals among 35.50- year-old apparently healthy men. Methods: We applied ACSM and ESC pre-participation screenings to 25 men participating in a study on first-time marathon running. We compared screening outcomes against medical history, physical examination, electrocardiography, blood tests, echocardiography, cardiopulmonary exercise testing, and magnetic resonance imaging. Results: ACSM screening classified all participants as "medical clearance not necessary."ESC screening classified two participants as "high-risk."Extensive cardiovascular evaluations revealed ≥1 minor abnormality and/or cardiovascular condition in 17 participants, including three subjects with mitral regurgitation and one with a small atrial septal defect. Eleven participants had dyslipidaemia, six had hypertension, and two had premature atherosclerosis. Ultimately, three (12%) subjects had a serious cardiovascular condition warranting sports restrictions: aortic aneurysm, hypertrophic cardiomyopathy (HCM), and myocardial fibrosis post-myocarditis. Of these three participants, only one had been identified as "high-risk"by the ESC screening (for dyslipidaemia, not HCM) and none by the ACSM screening. Conclusion: Numerous occult cardiovascular conditions are missed when applying current ACSM/ ESC screening strategies to apparently healthy middle-aged men engaging in their first high-intensity endurance sports event.
