Stroke risks rise in South Korea as carotid artery disease goes unnoticed

Stroke remains a leading cause of death in South Korea, ranking fourth among all causes of death. Recent data shows a rising trend, with the number of stroke patients increasing from approximately 620,000 in 2021 to an estimated 658,660 by 2025.

Medical experts highlight carotid artery stenosis as a significant, often asymptomatic risk factor. This condition occurs when plaque builds up in the arteries supplying blood to the brain, potentially leading to cerebral infarction. Because symptoms may not appear even when vessels are more than half narrowed, regular screenings such as carotid ultrasounds are recommended, especially for those with hypertension, diabetes, or a family history of stroke.

Additionally, transient ischemic attacks (TIAs), often called ‘mini-strokes,’ serve as critical warning signs. While symptoms like facial drooping, arm weakness, or speech difficulties may resolve quickly, they indicate a high risk of a major stroke occurring shortly thereafter. Medical professionals advise using the ‘FAST’ (Face, Arm, Speech, Time) method to recognize symptoms and seeking immediate emergency medical attention even if symptoms disappear.
