Prof Steinwender concludes that wearing the WCD provides effective and safe protection against SCD. Both international and national cardiological societies recommend the WCD for transient SCD risk. While we have powerful drugs available to improve heart function, they take time to develop their full effect. It is therefore a matter of course for us to protect high-risk patients with a defibrillator vest in the first three months and, if necessary, beyond that, says Prof Steinwender. He observed that about 50% of patients do not require an ICD due to improvement in LVEF.
