Warning for Heart Patients as UK Heatwave Approaches

As temperatures in the UK rise, those with heart conditions need to be aware of the dangers that hot weather can pose. The British Heart Foundation (BHF) warns that the heart must exert more effort to maintain a stable core temperature in high heat. This increase in temperature can lead to the dilation of blood vessels, potentially resulting in lowered blood pressure and heightened risks for individuals suffering from cardiovascular diseases. Senior cardiac nurse Ruth Goss highlighted the increased vulnerability of elderly individuals and young children, who find it harder to regulate their body temperatures, emphasizing the importance of keeping friends and family cool and comfortable during the heat.

To prevent complications, the BHF offers practical advice for individuals with heart issues, especially with temperatures in London and Cambridge expected to soar to 35C this week. Some essential tips include staying well-hydrated by drinking plenty of fluids, particularly water, while being mindful of fluid restrictions if advised by healthcare professionals. It's crucial to maintain a cool indoor environment by using blinds, covering windows from direct sunlight, and minimizing the use of electrical devices.

For those managing angina, extra caution should be taken with medications like GTN sprays, as these can cause rapid blood vessel dilation and a sudden drop in blood pressure, possibly leading to faintness. The advice also includes avoiding alcohol, consuming cold foods with high water content, and seeking shade during the peak heat hours of the day. Individuals are encouraged to avoid strenuous exercise and to wear light, loose-fitting clothing made of breathable fabrics. By following these guidelines, those with heart conditions can help safeguard their health during extreme heat.
