What is CVD?
Cardiovascular disease (CVD), is a group of conditions that includes stroke and heart disease. It kills one in three people in the UK.
CVD is caused by a build-up of fatty streaks and cholesterol in the blood vessels. While some contributing factors can’t be altered, we can change our lifestyle.
Natural wear and tear to blood vessels makes it easier for fatty cholesterol to leak in and get stuck to the artery walls. This build-up causes the arteries to narrow, reducing the heart’s ability to pump blood through them to the body. If they become completely blocked, it will cause a heart attack or a stroke if the blockage occurs in the brain’s blood vessels. Importantly, not all cholesterol is bad. There are two types of cholesterol in the bloodstream: LDLs and HDLs. LDLs create the build-up in arteries, while high HDL levels are a good sign that you’re not at risk of CVD.
