High blood pressure is a significant, often unnoticed, threat to cardiovascular health in Vietnam. Many individuals only seek medical attention when experiencing severe symptoms like headaches or dizziness. However, doctors at the Vietnam National Heart Institute and Bạch Mai Hospital report that most cases develop silently, lacking obvious symptoms. Despite the absence of noticeable warning signs, the condition progressively damages the cardiovascular system. This “silent killer” undermines heart health daily. Early detection and management are crucial, as the lack of immediate symptoms often leads to delayed treatment and increased risk of serious complications. Awareness of these silent risks is vital for protecting cardiovascular well-being.
