Abstract:

Objective    To investigate whether sexual activity after myocardial infarction can trigger a new myocardial ischemia or injury. Methods     A total of 32 men experiencing first myocardial infarction were examined. All subjects wore a Holter ECG during both sexual activity and physical exercise. Heart rate variability (HRV) and SDNN, SDANNI, RMSSD, LF,  HF were quantitatively analyzed. Results    The index of SDNN, SDANNI, RMSSD, LF, HF were 95.3ms, 76.5ms, 18.3ms, 738.5ms2, 520.7ms2 respectively during sexual activity; and 114.5ms, 87.4ms, 25.4ms, 583.7ms2, 548.5ms2 respectively during physical exercise. The differences were significant (P<0.01). Conclusion    Sexual activity might induce myocardial ischemia/injury or arrhythmia. Quantitative analysis of HRV can reflect vagal tone and sympathetic nerve activity, and therefore, it may guide safe sexual activity after myocardial infarction.

Key words: Myocardial infarction;   Sexual activity;   Heart rate variability
