          据估计，全世界有 10
          亿人患有高血压，来自美国全国健康和营养调查的数据（NHANES）显示，高血压的患病率呈逐年上升趋势。
          但是，我国高血压的控制程度非常不乐观，不少朋友担心降压药对肾的影响，有些甚至因为担心伤肾，而不敢吃降压药。
          我们就介绍一下，高血压对肾脏的危害，还有降压药对肾脏影响。
          没有耐心看的朋友，可以直接记住这个结论：高血压比降压药伤肾。千万不要因为担心副作用不敢吃药，那是「丢西瓜捡芝麻」得不偿失的行为

引入医生卡片组件

import DoctorCard from './DoctorCard.vue'

<van-swipe-item v-for="item in 5" :key="item">
  <doctor-card />
</van-swipe-item>          

去除指示器，关闭无缝滚动，设置一次滚动一个卡片

 <van-swipe :width="150" :show-indicators="false" :loop="false">

van-swipe组件固定150宽度的滚动距离，适配有问题
解决办法一

• 在 375 宽度设备，滚动宽度为 150
• 在其他设备需要等比例设置滚动的宽度
• scrollWidth = 150 / 375 * deviceWidth 就可以适配

import { onMounted, onUnmounted, ref } from 'vue'

const width = ref(0)
const setWidth = () =>  width.value = window.innerWidth
onMounted(() => {
  setWidth()
  window.addEventListener('resize', setWidth)
})
onUnmounted(()=>{
  window.removeEventListener('resize', setWidth)
})

<van-swipe :width="(150 / 375) * width" :show-indicators="false" :loop="false">

解决办法二
@vueuse/core

import { useWindowSize } from '@vueuse/core'
