Summer with LVAD: Your Guide to a Safe and Comfortable Season in the Sun

Why Are Heatwaves a Challenge for Your Heart?

When the temperature outside rises, our body triggers natural cooling mechanisms. The most important ones are sweating and the dilation of blood vessels near the skin. For a healthy person, this is a normal process, but for an LVAD patient, it means the circulatory system has to work harder.

High temperatures require the heart (supported by your pump) to circulate more blood to cool the body down. Additionally, intense sweating leads to the loss of water and electrolytes, increasing the risk of dehydration a condition particularly dangerous for cardiac patients.

Care for Your Equipment – It Doesn’t Like the Heat Either!

Your controller and batteries are your most important allies. However, remember that electronics have limits when it comes to heat tolerance. Extreme temperatures can affect battery performance and, in rare cases, the controller's operation.

How to protect your gear on hot days?

• Never leave gear in the car: Temperatures inside a parked car can skyrocket to dangerous levels in minutes. Always take your spare batteries with you.

• Avoid direct sunlight: Try to keep your bag with the controller and batteries in the shade. If you are relaxing outside, place your equipment under an umbrella or cover it with a light, bright cloth.

• Cool storage at home: Store your spare batteries and charger in the coolest room of your house, away from direct sunlight coming through windows.

Hydration is Key – Drink Smart

In hot weather, it’s easy to miss the moment your body starts needing water. As an LVAD patient, you cannot rely solely on the feeling of thirst by the time it appears, you may already be slightly dehydrated.

• Drink regularly: Always carry a water bottle and take small sips throughout the day.

• Water is best: Avoid sugary drinks, strong coffee, tea, and especially alcohol they act as diuretics and accelerate dehydration.

• Observe your body: Pay attention to the color of your urine (it should be pale straw) and watch for symptoms like dry mouth, dizziness, or weakness. If you are unsure about fluid limits (especially if you have right heart failure), consult your LVAD coordinator.

Comfort and Hygiene: Managing Sweat and Equipment Weight

Summer is when wearing extra equipment becomes more cumbersome. A heavy bag or vest can cause additional overheating, and sweat accumulating under clothing increases the risk of skin irritation.

Special attention must be paid to the driveline exit site. Moisture and heat create an ideal environment for bacteria, so keeping this area hygienic is a top priority in summer. Try to keep the dressing area dry and change it according to recommendations, or even more frequently if you feel it has become damp with sweat.

The Role of Proper Clothing This is where what you wear makes a huge difference. Regular cotton t-shirts soak up sweat quickly and become heavy, adding to your discomfort.

It is worth considering specialized clothing designed with LVAD patients in mind (like the solutions we create at LVADLINE). Garments made from modern, technical materials:

1. Wick moisture away, keeping the skin dry, which is crucial for driveline hygiene.

2. Are breathable and light, helping to prevent overheating.

3. Intelligently distribute the weight of the equipment, making carrying batteries and the controller less tiring, even on hot days.

Investing in professional medical wear is an investment in your peace of mind and comfort during the summer months.

Your Summer Action Plan – Practical Tips

Here are a few simple rules to help you enjoy summer safely:

• Plan your activity: Go for walks or run errands in the morning (before 10:00 AM) or late afternoon (after 5:00 PM) when the sun is less intense.

• Seek shade: When outside, always choose shaded areas.

• Wear light, breathable clothes: They reflect sunlight and aid thermoregulation. Don’t forget a hat!

• Listen to your body: If you feel tired, too hot, or dizzy do not ignore it. Stop your activity, sit in a cool place, and drink water.

• Stay connected: Always have a charged phone and your cardiology center’s number with you.
