Masters athlete screening study (MASS): incidence of cardiovascular disease and major adverse cardiac events and efficacy of screening over five years.

backgroundThe efficacy of cardiovascular screening in Masters athletes (MAs) (≥35 y), and whether screening decreases their risk of major adverse cardiac events (MACEs) is unknown. PURPOSE: To evaluate the effectiveness of yearly cardiovascular screening, and the incidence of cardiovascular disease (CVD) and MACE over five years. METHODS AND

resultsMAs (≥35 y) without previous history of CVD underwent yearly cardiovascular screening. Participants with an abnormal screen underwent further evaluations. In the initial year, 798 MAs (62.7% male, 55 ± 10 y) were screened; 11.4% (n = 91) were diagnosed with CVD. Coronary artery disease (CAD) was the most common diagnosis (n = 64; 53%). During follow-up, there were an additional 89 CVD diagnoses with an incidence rate of 3.58/100, 4.14/100, 3.74/100, 1.19/100, for years one to four, respectively. The most common diagnoses during follow-up were arrhythmias (n = 33; 37%). Increasing age (OR = 1.047, 95% confidence interval (CI): 1.003-1.094; P = 0.0379), Framingham Risk Score (FRS) (OR = 1.092, 95% CI: 1.031-1.158; P = 0.003), and LDL cholesterol (OR = 1.709, 95% CI: 1.223-2.401; P = 0.002) were predictive of CAD, whereas moderate intensity activity (min/wk) (OR = 0.997, 95% CI: 0.996-0.999; P = 0.002) was protective. Ten MACE (2.8/1000 athlete-years) occurred. All of these MAs were male, and 90% had ≥10% FRS. All underwent further evaluations with only two identified to have obstructive CAD.

conclusionMACE occurred despite yearly screening. All MAs who had an event had an abnormal screen; however, cardiac functional tests failed to detect underlying CAD in most cases. It may be appropriate to offer computed coronary tomography angiography in MAs with ≥10% FRS to overcome the limitations of functional testing, and to assist with lifestyle and treatment modifications.
