What causes heart disease?
Heart disease is caused by a furring up of the arteries with fatty deposits, a process known as atherosclerosis. This leads to narrowing arteries, which eventually stops enough oxygen reaching the heart, causing chest pain (angina). If the artery becomes blocked with a clot, this can result in a heart attack.
But heart disease doesn't just creep up on us overnight - it's the accumulation of unhealthy lifestyle choices made over many decades, including:
- too much saturated fat
- weight gain
- high blood pressure
- raised cholesterol
- not enough exercise
It's never too early to start thinking about your heart health though, so here's a step-by-step guide to keeping your heart healthy - at each stage of your life.
