Heart disease continues to be the leading cause of death globally, responsible for millions of fatalities each year. Heart attacks and strokes alone make up nearly 85% of cardiovascular-related deaths, highlighting the critical need for prevention. Despite significant advances in medical treatments, experts stress that the most effective strategies are often simple and proactive: maintaining a heart-healthy lifestyle and identifying risks early. By eating a balanced diet, exercising regularly, managing stress, and monitoring blood pressure and cholesterol, individuals can significantly reduce their chances of severe heart events. Even for those with a family history of heart disease, these preventive measures provide a powerful way to safeguard long-term cardiovascular health.
Heart disease is largely preventable through early risk management: Study reveals
A landmark study published in the Journal of the American College of Cardiology provides eye-opening evidence about the preventable nature of heart disease. Researchers discovered that more than 99% of individuals who experienced a heart attack, stroke, or heart failure had at least one major risk factor at unhealthy levels long before their health crisis.
The study analysed long-term health records of over 9 million South Koreans and nearly 7,000 participants in the United States, offering an unprecedented view of how cardiovascular risk factors accumulate over time. The findings indicate that most heart disease events are predictable and preventable, rather than random or purely genetic.
High blood pressure, cholesterol, diabetes, and smoking: Major heart disease risks
The research highlighted four key modifiable risk factors that often go unnoticed until it’s too late:
- High blood pressure (hypertension)
- High cholesterol levels
- High fasting glucose or diabetes
- Tobacco use
Among these, high blood pressure emerged as the most common risk factor, affecting over 95% of South Korean participants and more than 93% of U.S. participants.Philip Greenland, senior author of the study and professor at Northwestern University Feinberg School of Medicine, emphasized:“These are the major risk factors and they are modifiable. If they are present in almost all cases, then there is an opportunity for prevention.”This underscores a critical point: early identification and management of these risk factors can drastically reduce the likelihood of heart attacks, strokes, and heart failure.
Hidden cardiovascular risk factors can cause irreversible damage
One of the most insidious aspects of cardiovascular risk factors is their silent nature. Many people with high blood pressure, elevated cholesterol, or abnormal glucose levels experience no obvious symptoms for years. By the time symptoms appear, irreversible damage may already have occurred to the heart, arteries, or brain.Even groups typically considered low risk—such as younger women—were found to possess at least one unhealthy factor prior to experiencing a cardiovascular episode.
Lifestyle changes that reduce heart risk
The study reinforces a clear message: heart disease is largely preventable through manageable lifestyle modifications. Effective strategies include:
- Quitting smoking, which protects arteries, reduces inflammation, and lowers cardiac stress
- Adopting a heart-healthy diet rich in fruits, vegetables, whole grains, and lean proteins to maintain optimal cholesterol and glucose levels
- Engaging in regular physical activity, such as walking, cycling, or aerobic exercise, to strengthen cardiovascular function
- Monitoring blood pressure, cholesterol, and glucose regularly to identify and address abnormal readings early
Implementing these measures can significantly reduce the risk of heart attacks and strokes, even for individuals who already exhibit risk factors. Preventive action is not only possible but highly effective.
Understanding the warning signs of heart attacks
Most heart attacks and strokes do not occur suddenly without warning. In many cases, subtle signs develop years before a major cardiovascular event. These may include elevated blood pressure, prediabetic glucose levels, or early arterial plaque buildup, which can be detected through routine medical exams.By recognizing these warning signs early and making targeted lifestyle and medical interventions, individuals can dramatically lower their risk of life-threatening cardiovascular events and improve long-term health outcomes.Also Read | Angioplasty vs. Bypass: Which heart procedure is best for your blockages, age, and overall health
