“Most clinical trials have been heavily weighted toward men; therefore, generalization of the results to women remains questionable. The best answer to this problem would be to perform a clinical trial that specifically targets women with heart failure to test the hypothesis of whether implantable cardioverter-defibrillator implantation reduces their overall mortality [death] rate,” the authors write. Because clinical guidelines already recommend defibrillator treatment to prevent sudden cardiac death, such a trial may be difficult to propose, they note. “However, on the basis of our findings it seems that a trial targeting women is needed, and a meta-analysis such as ours may be an appropriate first step to explore this hypothesis.”
