“This is the first time it has been reported that there is an association between sex hormone levels and sudden cardiac arrest,” said Dr Sumeet Chugh, MD, director of the Heart Rhythm Center in the Cedars-Sinai Heart Institute and the Pauline and Harold Price Chair in Cardiac Electrophysiology Research.
Pertinent Findings:
• Men who had sudden cardiac arrests had testosterone levels of 4.4 nanograms per milliliter, compared to 5.4 nanograms per milliliter for men who did not have sudden cardiac arrest.
• Men who had sudden cardiac arrest had estradiol levels of 68 picograms per milliliter, compared to 52 picograms per milliliter for men who did not have sudden cardiac arrest.
• Women who had sudden cardiac arrest had estradiol levels of 54 picograms per milliliter, compared to 36 picograms per milliliter for the control group.
