Heart disease is the leading cause of death globally, and Korea's healthcare system has invested heavily in world-class cardiac care to address it. Understanding risk factors and prevention is the most powerful tool available.
Cardiovascular disease (CVD) encompasses a group of conditions affecting the heart and blood vessels, including coronary artery disease (CAD), heart failure, arrhythmias, and valvular heart disease. Coronary artery disease — caused by the gradual narrowing of arteries supplying the heart due to atherosclerosis (plaque buildup) — is the most common form and the leading cause of heart attack.
Korea has responded to the cardiovascular health challenge with exceptional investment in cardiac infrastructure. Major hospitals such as Samsung Medical Center and Asan Medical Center in Seoul operate world-class tertiary cardiac centres offering interventional cardiology, cardiac surgery, electrophysiology, and cardiac rehabilitation. Private cardiac clinics across Seoul provide accessible specialist care. Korea's cardiologists are trained at leading international institutions and equipped with cutting-edge technology.
The key message from Korea's national health policy is that cardiovascular disease is largely preventable. The main modifiable risk factors — high blood pressure, high cholesterol, type 2 diabetes, smoking, physical inactivity, obesity, and unhealthy diet — are all addressable through lifestyle change and, when needed, medication. Community health centres offer cardiovascular risk assessment and early intervention programmes. Knowing your numbers (blood pressure, cholesterol, blood sugar, BMI) is the first step to protecting your heart.
Key Points
- Korea's major hospitals — world-class cardiac care in Seoul
- Coronary artery disease is the most common type — caused by arterial plaque buildup
- 80% of heart attacks are preventable with lifestyle modification
- Know your numbers: blood pressure, cholesterol, blood sugar, BMI
- NHIS national health screening offers cardiovascular risk assessment for eligible adults
- Early warning signs: chest pain, shortness of breath, fatigue — never ignore them
Causes & Risk Factors
- High blood pressure (hypertension) — damages arterial walls over time
- High LDL cholesterol — contributes to plaque formation in arteries
- Type 2 diabetes — accelerates arterial damage
- Smoking — directly damages blood vessels and accelerates atherosclerosis
- Physical inactivity and obesity
- Family history and genetic predisposition
When to See a Doctor
- Chest pain, pressure, tightness, or discomfort — call 119 immediately if sudden or severe
- Shortness of breath at rest or with minimal exertion
- Annual cardiovascular risk check if you are over 40, diabetic, or have a family history of heart disease
- If you have two or more risk factors: hypertension, diabetes, smoking, high cholesterol, obesity
- After a heart attack or cardiac procedure — regular follow-up is essential
For emergencies in Korea, call 119
