Don’t hibernate your heart in cold weather

We’re coming to the end of one of the coldest winters in 20 years but people at risk of heart problems should continue to take preventative measures to reduce the likelihood of suffering an attack.

The North Shore Heart Research Foundation (NSHRF) warns that cardiovascular disease is the leading cause of death in the developed world.

“Recent studies demonstrate that more heart attacks occur during winter than any other season,” says Dr Peter Caspari, NSHRF director and leading cardiologist at the Royal North Shore Hospital.

Cold weather risk factors identified by Dr Caspari include:
• respiratory infections
• increased consumption of fatty foods and salt
• increased blood pressure, cholesterol and weight
• decreased activity
• tobacco and alcohol use

You will not necessarily develop cardiovascular disease if you have a risk factor. However, the more risk factors you have the greater the likelihood that you will deveop cardiovascular dieseae, unless you take action.

Hypertension is the single biggest risk factor for stroke and also plays a significant role in heart attacks. It can be prevented and successfully treated but only if you have it diagnosed and stick to your recommended management plan.

Physical inactivity increases the risk of heart disease and stroke by 50%. When the weather is cold or damp, our motivation to stay physically active can plummet, especially when it comes to outdoor activity.

By decreasing our physical activity, we 'hibernate' our hearts, which is not good for them.

Obesity is also a major risk for cardiovascular disease and predisposes you to diabetes. Having diabetes makes you twice as likely to develop cardiovascular disease as someone who does not.

The North Shore Heart Research Foundation has 14 research projects underway aimed at furthering knowledge of heart disease and supporting research into its treatment and prevention.

The Foundation also It also provides financial support to cardiologists, surgeons and medical researchers at Royal North Shore Hospital for a wide range of programs looking at or treating cardiovascular disease and associated medical conditions.

Don’t neglect your heart. Take it out for a walk on even the coldest day!
