Sumary of You could be at risk of having a heart attack this winter warns study – how to reduce risk:
- Researchers have warned of the perils of cold weather for the heart, as a drop in temperatures often confers higher prevalence in heart attacks.
- “Instead, we found that they ended up having more fat stored in the blood vessels.
- ”The researchers determined that exposure to low temperatures accelerated the formation of atherosclerotic plaque in the mice, which is a known trigger for myocardial infarction – or heart attack – and brain haemorrhaging.
- DON’T MISS: For the study, the team created genetically modified mice that were especially prone to atherosclerosis.
- Researchers observed that colder conditions prompted the conversion of white fat into brown fat, which produces heat as it is broken down.
- As LDL cholesterol is deposited in the arteries, a build-up of plaque can eventually obstruct blood flow to the heart, triggering a heart attack.
- To further test the causal link between heart generation and LDL production, researchers created atherosclerosis-prone mice that were unable to use their brown fat to produce heat.
