Coronary Artery Disease (CAD) is one of the leading causes of death in Singapore, where heart disease consistently ranks among the top health concerns. Many misconceptions about this health issue persist, are coronary artery disease myths may prevent people from taking proactive steps toward prevention and treatment. This article uncovers the truth behind five of the most common myths about coronary artery disease. We separate medical fact from fiction to help you make informed decisions about heart health.

Myth 1: Coronary Artery Disease Only Affects The Elderly
Fact: While the risk of CAD increases with age, it is not a disease confined to the elderly. In Singapore, doctors have observed more cases of heart disease among people in their 30s and 40s. The rise in sedentary lifestyles, poor dietary habits, and high stress levels among younger adults has contributed significantly to this trend.
According to the Singapore Myocardial Infarction Registry 2022, about 7% of heart attacks in Singapore in 2022 happened to people under the age of 50. Genetics, smoking, diabetes, and obesity also increase the risk of developing CAD earlier in life. Regular health screenings, even for younger adults, are crucial for early detection of high blood pressure, high cholesterol, and other cardiovascular risk factors.
Myth 2: If You’re Fit And Active, You Won’t Get Heart Disease
Fact: While regular exercise is beneficial for heart health, it does not make anyone immune to CAD. Some individuals with active lifestyles have underlying risk factors such as high cholesterol, hypertension, or a family history of heart disease that can still lead to blocked arteries.
In Singapore, even athletes have occasionally suffered cardiac events due to genetic predispositions or unrecognised heart abnormalities. Being physically active should always be complemented with routine health checks, a balanced diet, and control of other risk factors. Exercise helps to lower the risk, but it does not erase it. This highlights the importance of a comprehensive approach that combines fitness with medical monitoring and healthy lifestyle choices.
Myth 3: Coronary Artery Disease Is A Man’s Disease
Fact: Although men tend to develop CAD at a younger age, women are equally susceptible, especially after menopause when oestrogen levels drop. In Singapore, heart disease is the leading cause of death among women, surpassing cancers such as breast and ovarian cancer.
Unfortunately, many women dismiss early warning signs like shortness of breath, fatigue, or nausea, attributing them to stress or other conditions. Moreover, women are less likely to seek immediate medical help during a heart attack because their symptoms often differ from the classic “chest pain” associated with men.
Healthcare professionals emphasise that awareness and early intervention are key. Women should know their numbers — cholesterol, blood pressure, and blood sugar — and discuss heart health proactively with their doctors.
Myth 4: You Cannot Reverse Or Improve Coronary Artery Disease
Fact: While CAD cannot always be completely reversed, it can be effectively managed and its progression slowed — and sometimes even partially reversed — through lifestyle modifications and medication. Studies have shown that quitting smoking, maintaining a healthy diet, and engaging in regular physical activity can improve blood vessel function and reduce plaque buildup.
In Singapore, public health initiatives such as the War on Diabetes and Healthier SG campaigns encourage citizens to adopt healthier lifestyles to reduce chronic disease risks, including heart disease. Advances in medical treatments — such as statins, stents, and minimally invasive bypass surgery — have also improved outcomes dramatically.
Furthermore, the adoption of heart-healthy diets like the Mediterranean or DASH diets, which emphasise whole grains, lean proteins, fruits, and vegetables, can significantly lower cholesterol and improve cardiovascular health.
Myth 5: Once You Start Heart Medication, You Will Need It For Life
Fact: While some medications for CAD, such as cholesterol-lowering drugs and blood thinners, may be long-term, they are not necessarily lifelong if risk factors are well controlled. The goal of treatment is to stabilise plaque, reduce inflammation, and improve heart function.
If patients make significant lifestyle changes and maintain optimal heart health, doctors may safely reduce or adjust medication doses over time. However, stopping medication without medical supervision can be dangerous. Each patient’s case is unique — and decisions should always be guided by a cardiologist.
In Singapore’s healthcare system, the emphasis is on personalised medicine, where treatment plans are tailored according to individual risks and responses. Regular follow-ups and open communication with healthcare providers help ensure safe and effective management.

The Bottom Line: Awareness Saves Lives
Coronary Artery Disease is largely preventable through a combination of healthy lifestyle choices, early detection, and appropriate medical care. Dispelling myths is essential, as misinformation can delay diagnosis or discourage individuals from seeking help.
Whether you are young or old, male or female, active or sedentary, heart health should always be a priority. Understanding the facts about coronary artery disease and acting on them can make the difference between prevention and crisis. A healthy heart begins with knowledge, and knowledge begins with separating myth from fact.
