Is kava bad for your heart?

Could you elaborate on the potential impact of kava on heart health? I've heard some conflicting views regarding its safety, specifically for those with pre-existing heart conditions. Some studies suggest that it may have calming effects, while others raise concerns about potential negative interactions with heart medications or an increased risk of arrhythmias. As a professional in the field of finance and cryptocurrencies, I'm curious to understand the scientific consensus regarding this traditional herbal remedy and its potential cardiac effects. Could you provide some clarity on this topic?
