Extreme weather conditions always affect people with chronic ailments and diseases. It was observed long ago that during extreme heat waves, there is an increase in the rate of heart attacks and decompensated heart failure. Our body cools itself by sweating.
The higher the temperature and humidity, the more vessels in the skin the body opens up to expand the cooling surface. For the heart, this means that there are more vessels to pump the blood through, so the heart has to beat faster to provide sufficient flow. A faster-beating heart means more work for the heart muscle and people with more advanced heart disease may not be able to compensate for this increase in workload.
As a result, we see more patients with heart attacks or decompensated heart failure. During extreme heat periods, patients with chronic heart conditions should avoid strenuous activities, stay in an air-conditioned environment, and ensure appropriate hydration.
Also, when sweating, we lose salt and minerals. The task of balancing this loss of salt with a heart failure patient’s salt-restricted diet becomes a difficult one. For these patients, the safest way to replenish fluids is by drinking sport beverages, which usually have some salt and minerals.
Sherman Hospital has an excellent Heart Failure Recovery Center to help our patients with these problems.
