胆固醇如何影响心血管健康?

How does cholesterol affect cardiovascular health?

低密度脂蛋白胆固醇(LDL)过高会在动脉壁沉积形成斑块,使血管变窄、增加心脏病和中风风险;高密度脂蛋白(HDL)则有助于清除胆固醇。
High LDL cholesterol builds plaques in artery walls, narrowing vessels and raising heart attack and stroke risk, while HDL helps remove cholesterol.

心肺复苏(CPR)的原理是什么?

What is the principle behind CPR?

心肺复苏通过胸外按压维持人工循环,把血液压向大脑和心脏,配合人工呼吸提供氧气,在心跳停止时争取抢救时间。
CPR uses chest compressions to maintain artificial circulation, pushing blood to the brain and heart, with rescue breaths supplying oxygen, buying time when the heart stops.

为什么运动时心跳会加快?

Why does the heart beat faster during exercise?

运动时肌肉需要更多氧气和养分,心脏便加快跳动、加强收缩,以更快输送血液满足需求。
During exercise, muscles need more oxygen and nutrients, so the heart beats faster and stronger to deliver blood more quickly.
