Several South Korean news outlets reported on September 9, 2026 that heart conditions common among adults in their 40s to 60s can show warning signs that appear on the fingernails. According to 헬스조선, pressing down on a nail can reveal indicators linked to heart disease in this age group.
서울경제 also covered the topic, framing the nail-pressing observation as a possible signal of a condition that poses a risk to people in their 40s, 50s and 60s. 아시아경제 reported that doctors pointed to unusual nail color as a potential sign of heart problems.
A separate report from 매경헬스 focused on chest sensations during physical activity, describing a stinging or prickling feeling in the chest while exercising as a possible danger signal from the heart. 경북매일, in a health column, advised that chest pain lasting longer than five minutes should prompt a call to emergency services, noting that heart attacks and strokes are a race against time.
