I have had high blood pressure for many years. Recently, every time I take a hot shower, I often feel slightly dizzy and sometimes my heart beats fast. Is this a warning sign of heart disease? (Nguyen Thi Binh, 63, Hung Yen)

Transient chest pain, mild shortness of breath during physical activity, rapid heartbeat, and prolonged fatigue are warning signs of cardiovascular disease in young people but are often mistaken for stress.

Controlling blood pressure and blood sugar, managing stress, and dedicating a few minutes to breathing exercises before sleep can help lower the risk of a heart attack.
