Fatigue and low blood pressure: cardiologists' tips for summer

The heart is among the organs most exposed to the risks of summer heat. Palpitations, low blood pressure, and fatigue can be warning signs that shouldn't be ignored, especially for those suffering from cardiovascular disease. This is what experts at the Fondazione per il Tuo Cuore and the National Association of Hospital Cardiologists (ANMCO) are reminding us, recommending paying attention to warning signs and adopting a healthy lifestyle to prevent complications.

"The first effects of heat on the cardiovascular system essentially consist of vasodilation, which often leads to a drop in blood pressure," explains Domenico Gabrielli, president of the Fondazione per il Tuo Cuore and director of Cardiology at San Camillo Hospital in Rome. "To compensate, the heart can increase its beats and suffer. The most obvious symptom can be palpitations, which are often accompanied by persistent weakness. This should be taken seriously when the heart rate consistently exceeds 100 beats per minute."

It's also important to monitor blood pressure, especially in patients already undergoing medication. "Those taking antihypertensive medications should check their blood pressure more frequently, and if they find low values, they should report it to their doctor as soon as possible so that treatment can be adjusted if necessary. This should obviously never be done independently."

To protect your heart during the summer, experts recommend taking some precautions: stay adequately hydrated, eat a light diet, avoid going out during the hottest hours of the day, and pay attention to the signals your body sends. "If your blood pressure tends to be low, but your heart is healthy, it's best to increase the amount of salt in your condiments," says Massimo Grimaldi, president of the National Association of Cardiology (ANMCO) and director of Cardiology at Miulli Hospital in Acquaviva delle Fonti (Bari). "On the other hand, if you have hypertension or heart failure, it's best to consult your doctor, as excess salt and water could be harmful."
