World Heart Day (WHD) was established in partnership with the World Health Organization (WHO) with a mission to raise global awareness and inspire action against cardiovascular disease, one of the leading causes of death worldwide. By recognising and observing this day, which falls on September 29 annually, the goal is to educate people on the importance of heart health and motivate them to adopt healthier lifestyles. Celebrating World Heart Day by spreading accurate information is vital because knowledge is the first step towards prevention. On this day, let’s take the opportunity to debunk common myths about heart disease and empower individuals with the facts to protect their hearts.
Heart health is often misunderstood, with plenty of myths floating around. You might think that heart disease only affects older people or those with poor diets, but the reality is different. Heart disease can impact anyone, regardless of age or lifestyle. Misconceptions can be risky, especially when heart disease is the leading cause of death among adults globally.
Here are 10 common myths and facts related to heart diseases, as pointed out by the American Heart Association (AHA):
“I’m too young to worry about heart disease.”
Age is not a safeguard against heart disease. The habits you adopt in your youth influence your cardiovascular health later in life. Arterial plaque buildup can begin as early as childhood and continue through adolescence, eventually causing clogged arteries. Almost half of U.S. adults aged 20 and older have cardiovascular disease, and many of them are not elderly. Even young adults and those in middle age can face heart-related issues, especially with obesity, Type 2 diabetes, and other risk factors becoming prevalent earlier in life.
“I’d know if I had high blood pressure because there would be warning signs.”
High blood pressure is often called the “silent killer” for a reason—there are typically no symptoms. Many people don’t realise they have it until it’s too late. The only way to know is by checking your blood pressure regularly. Without treatment, high blood pressure can lead to severe health complications like heart attacks, strokes, and kidney damage. Knowing your numbers is crucial to avoid these outcomes.
“I’ll know when I’m having a heart attack because I’ll have chest pain.”
Chest pain is a common symptom, but it’s not the only sign of a heart attack. Sometimes, the signs are more subtle, such as shortness of breath, nausea, dizziness, or discomfort in areas like the arms, jaw, neck, or back. Even if you’re uncertain whether you’re having a heart attack, it’s always best to call 911 immediately. It’s better to be cautious and prevent further damage.
“Diabetes won’t harm my heart as long as I take my medication.”
Managing diabetes does help, but it doesn’t eliminate the risk of heart disease. People with diabetes are still more likely to develop heart issues because diabetes shares many risk factors with cardiovascular disease, such as high blood pressure, obesity, and inactivity. While medication is crucial, it’s also important to tackle these other risk factors to protect your heart.
“Heart disease runs in my family, so there’s nothing I can do to prevent it.”
Having a family history of heart disease does put you at greater risk, but that doesn’t mean you’re powerless. You can significantly reduce your risk by adopting heart-healthy habits like exercising regularly, managing cholesterol and blood pressure, eating a balanced diet, maintaining a healthy weight, controlling blood sugar levels, managing stress, getting adequate sleep, and avoiding smoking.
“I don’t need to have my cholesterol checked until I’m middle-aged.”
It’s never too early to start monitoring your cholesterol. In fact, doctors recommend checking your cholesterol levels as early as your 20s. Young adults with slightly elevated LDL (bad cholesterol) levels (160-189 mg/dL) may already need cholesterol-lowering medications. Risk factors for heart disease should be checked every four to six years after the age of 20, and a heart-healthy lifestyle can make a huge difference.
“Heart failure means the heart stops beating.”
Heart failure doesn’t mean the heart stops—it just means it can’t pump blood efficiently. This can lead to symptoms like shortness of breath, swelling in the feet and ankles, or a persistent cough. Cardiac arrest, on the other hand, is when the heart suddenly stops beating, causing unconsciousness and abnormal breathing. Both conditions are serious, but they are not the same.
“This pain in my legs is just a part of getting older. It can’t be related to my heart.”
Leg pain, especially in the muscles, may actually be a sign of peripheral artery disease (PAD), a condition caused by plaque buildup in the leg arteries. PAD increases the risk of heart attacks or strokes, making it crucial to address the issue sooner rather than later.
“My heart is racing, so I must be having a heart attack.”
It’s normal for your heart rate to vary depending on your activity level or emotions. However, in some cases, a rapid heartbeat could indicate arrhythmia, an irregular heart rhythm. While some arrhythmias are harmless, others may need treatment if they affect how well your heart pumps blood.
“I should avoid exercise after suffering a heart attack.”
Exercise is essential, even after recovering from a heart attack. Starting a moderate exercise routine—approved by your doctor—is one of the best things you can do for your recovery and overall heart health. Studies show that survivors who stay active live longer than those who don’t. Experts recommend at least 150 minutes of moderate physical activity weekly for heart health. You can also benefit from joining a cardiac rehab programme for tailored advice and support, but make sure to consult your healthcare provider first
