The ST segment depression pattern in asymptomatic peri-menopausal female athletes

Background ST segment has not been well investigated in asymptomatic peri-menopausal female athletes, when the CV risk is higher. Aims The aims of the study is to investigate the prevalence of ST segment depression in peri-menopausal female athletes, divided in four age groups. Methods in a cohort of 6010 female athletes aged 45-65 years old, 161 subjects were selected for the presence of ST segment depression, revealed by maximal ergometric test. All athletes were also evaluated by physical examination and echocardiography. Inclusion criteria for ST segment depression were ST depression >0.5 mm respect to baseline and its depth was divided in 0.5 mm, 0.5-1 mm, 1-2 mm categories. Its behavior was classified in ascending, horizontal and descending and it was studied in relation to the age range ( 60). Results ST segment depression was mainly evident in inferolateral leads in all groups (63%, 70,3%, 71%, 63,6%, for <51; 51-55, 56-60 and 61-65 respectively) with horizontal pattern (52,2%, 59,5%, 57,8%, 63,6%) and 1-2 mm depth (43,5%, 46,7%, 60,6%), with the exception of the range 51-55, mainly showing a depth of 0,5-1 mm (45,9%). The older group showed increased SBP (137.5 mmHg, p = 0.007) and BMI (24.3, p = 0.093) values. Mitral prolapse was shown in 11,8% while 36,6% showed systolic flattening of mitral leaflets. Conclusions ST depression in asymptomatic menopausal female athletes is frequent and it is characterized by a specific presentation pattern. This is particularly important in the menopausal age when CV risk factors are more prevalent.
