The sudden cardiac death among athletes is one of the most threatening tragedies that happen from time to time. In athletes older than 35 years of age, 80% of SCD is frequently due to atherosclerotic coronary artery disease. The strong relationship between CAD and increased arterial stiffness has been proven by several studies.
Studies suggest that arterial stiffness is a particularly important marker of subsequent cardiovascular morbidity and mortality among those with chronic cardiovascular or metabolic diseases. Children and adolescents with chronic diseases or disabilities have lower cardio-respiratory fitness (CRF), thus a higher prevalence of obesity. This needs further investigation regarding arterial parameters in mentioned subjects.
"Oxygen uptake per body weight" and "fat free mass" measured upon customised cardio-respiratory fitness. BMI and waist circumference calculated as well. Arterial stiffness and Total Peripheral Resistance also assessed by PWVao and AIx respectively which were measured by Arteriograph.
Results showed that lower oxygen uptake and higher waist circumference are related to higher PWV. On the other hand, higher BMI and waist circumference showed to be associated with lower AIx in youth with physical disabilities.
Coronary artery disease (CAD) is the main cause of exercise-related sudden cardiac death. This indicate that early identification of sub-clinical CAD should be an important goal in the pre-participation sports evaluation of middle-aged persons.
This study sets out to determine the value of Pulse Wave Velocity (PWV) evaluated with Arteriograph, in addition to routinely assessed cardiovascular risk factors (SCORE), to detect CAD in asymptomatic middle-aged sportsmen.
Results support the association between established risk factors (including smoking), arterial stiffness and CAD in middle-aged sportsmen. Furthermore, PWV measurements may have a role in the routine Sport Medical Evaluation (SME) of middle-aged sportsmen to help identify those at a higher risk for relevant CAD.
