Phi, 32 years old, experienced chest pain while playing football, initially thinking it was muscle soreness from exercise. When the pain persisted even at rest, doctors diagnosed him with a heart attack.

Approximately 220,000 Vietnamese die from cardiovascular diseases each year, with myocardial infarction accounting for about one-half, and patients are getting younger.

A 68-year-old man, experiencing chest pain for 3 days, called for an at-home IV drip, leading to a severe drop in his heart rate and a subsequent diagnosis of myocardial infarction upon hospital admission.
