Abstract:
Objective To investigate the relationship between regular exercise habit and peak oxygen uptake (VO2 peak ) early after acute ST-elevation myocardial infarction (STEM I).Methods A total of 239 patients who underwent cardiopulmonary exercise testing (CPET) early after STEMI in a single exercise laboratory were enrolled.Influencing factors to VO2peak were analyzed retrospectively.Results There were 53.6％ patients reported to have regular exercise habits before STEMI.No significant difference between patients with and without exercise habit in VO2peak early after STEMI (P =0.317) were found by t test.Mter adjusted by risk factors including demographic features,clinical characteristics and cardiovascular,etc,regular exercise habit was an independent factor for VO2peak (β =1.703,P =0.015 ).Following age-stratification,the significant difference was found between patients with and without exercise habits in VO2peak only in patients aged between 40-49 years old ( P =0.004 ).Conclusions The relationship between regular exercise habit and VO2peak early after STEMI suggests that exercise tolerance of patients with exercise habit will be better than sedentary patients even after STEMI,in particular to patients aged between 40-49 years old.
