15 yr-old boy with blood pressure of 135/65, pulse 68 weight 127lbs and 5'11 ? Is he at risk for heart problems? Has always been very active. Wants to play soccer in the school team and states that after very strenuous exercise he feels stabbing mild pain in the heart area which goes away after resting for ~5min. I m concerned because I know a boy who died playing basketball at age 18.
