Well, I'll let Bob talk a little bit about some of the potentially other macro factors. But the ones you've just mentioned here. I mean China, it's an important market for us, Vijay. It's an important growth market, and it's good that it's moved to a more kind of reopening play. I think that has not only a big impact for us in China, where we've got a strong position. I mean, we're not overly reliant, I'd say it's about less than 5% of our total sales. But nonetheless, it's an important kind of growth market for us.
And I think that reopening in China is going to have a real positive spillover effect in other areas of the world. And I would say, predominantly in Asia, Southeast Asia, where we've got strong position in our EPD and in our Nutrition business and some device areas, too. So I think the overall opening of China is good. Like Bob said, there's going to be some choppiness in the first quarter because we're seeing a lot of cases, hospitalizations, et cetera. But I think as that moves -- starts to move down, I think we'll see a pretty strong rebound in our growth prospects over there.
So the VBP that you mentioned, yes, I mean, that does have an impact. It's more restricted for 2023 in our electrophysiology business. So we'll feel a little bit of an impact there, but I think that the market opens up for us because of the strategy we took on VBP side. So I think it's net-net, it's going to be positive for us in the long term here, medium, long term in terms of that being an opportunity for us. We've seen this, Vijay. I mean, this happened to us -- this happened in the market with stents in 2019, in our vascular business. That business is back to what I would call pre VBP levels this year. So there's an impact.
In that case, we didn't necessarily win some of the contracts. In the case of VBP, we did win the contracts, so -- or a portion of the contract. So I'd say macro, yes, we've got some of these headwinds that we've talked about FX. I think Bob has already talked about it, inflation. But all those seem to be easing off a little bit and the recovery of the procedures and the pipeline and the product launch is a key growth driver for us.
