Cardiovascular diseases are the leading cause of death globally, affecting nearly 17.9 million people each year, according to the World Health Organization (WHO). ‘Heart diseases’ or ‘cardiovascular diseases’ are umbrella terms that encompass a wide variety of diseases like angina, heart attacks, strokes, arrhythmia etc. These problems are often caused by fatty deposits building up inside the arteries. The reason why these clogs cause as issues is because they stop the blood from flowing to and from necessary body parts, depriving them of air as well as nutrients. This can also lead to damage in other vital organs like the brain, the heart itself, the kidneys, and even the eyes. There are many different types of heart diseases, as well as many symptoms. The most common ones that many people know of are chest pain, sudden shortness of breath, irregular heartbeats, extreme fatigue, etc. However, there are also many subtle signs of heart diseases that you may not know of. How Many People Know of This Subtle Symptom It's important to know that the symptoms of heart disease can be different for each person. Because of this variability, some individuals might not even realize that the warning signs they are experiencing could be related to a serious heart condition. A recent survey conducted by LloydsPharmacy Online Doctor, involving 500 adults in the UK, found a concerning lack of awareness about certain heart disease symptoms. Specifically, only 46 percent of those surveyed knew that swelling in the legs could be a sign of heart problems. This lack of knowledge is concerning because if people don't know that leg swelling can be related to their heart, they might not take it seriously or go to the doctor to get it checked out, potentially missing an important early sign of heart trouble. When the survey asked about well-known signs of heart disease, most people got some of them right. A large majority knew that chest pain, especially if it feels like pressure or squeezing, could be a sign of a heart problem needing immediate attention. Many people also knew that feeling very out of breath and having an irregular heartbeat could be linked to heart issues. These are important symptoms for everyone to be aware of, as they are often key indicators that something might be wrong with the heart. Lesser Known Symptoms While many people knew about chest pain and shortness of breath, the survey showed that other important symptoms of heart disease were not as widely recognized. Feeling extremely tired all the time, even when you haven't done much, can be a sign. Also, as mentioned before, swelling in the legs, which happens when fluid builds up, is another symptom that many people don't realize could be related to their heart. Being aware of these less common signs is crucial for early detection. The fact that many people don't know about all the different ways heart disease can show itself highlights why it's so important to learn about a wide range of potential warning signs. Relying only on the most commonly known symptoms like chest pain might cause people to ignore other important signals their body could be sending them. Recognizing less obvious signs, such as unusual fatigue or swelling in the legs, could lead to earlier diagnosis and treatment, which can make a big difference in managing heart conditions and improving health outcomes.
