How to Assess Risk & Prevent Heart Disease | Dr. Andy Galpin
In a Nutshell
High-risk groups—particularly black male basketball players and athletes in rowing, running, cycling, swimming, or skiing—need targeted cardiac screening, with rates of sudden death reaching 1 in 4,000 for the highest-risk cohort. Family history of early heart disease is the strongest predictor, as shown by Joel Jamieson’s case of 50% widowmaker blockage despite elite fitness and zero symptoms. When imaging detects abnormal heart size, a 3-month detraining period distinguishes exercise-induced enlargement from genetic pathology, and genetically susceptible individuals should cap exercise at about 5 hours per week.

Targeted screening should begin with the most affordable and reasonable approaches. The most susceptible sports to cardiac issues are rowing, running, cycling, swimming, and skiing. For athletes in these sports, additional resources should be allocated for screening purposes. Basketball also carries increased risk of sudden cardiac death. Historical cases include Reggie Lewis and Hank Gathers who died in back-to-back years (1992-1993). The rate of sudden cardiac death in black male college athletes is approximately 1 in 16,000. For male basketball players specifically, the rate increases to 1 in 9,000. Among male black basketball athletes, the rate reaches approximately 1 in 4,000. While these rates are not extremely high, they represent a signal that warrants targeted screening for these high-risk groups prior to participation or every couple of years.
Any individual with a family history of early heart disease should receive cardiovascular screening. If anyone in the immediate or secondary family has died of heart disease earlier than age 55, cardiovascular screening is strongly recommended. The Joel Jamieson case illustrates this risk: despite being a world-renowned expert in cardiovascular exercise and endurance training who does not smoke, drink, or party, sleeps well, manages stress, maintains lean body composition, and has a VO2 max upwards of 55, he discovered a 50% blockage in his widowmaker artery at age 40 with zero symptoms. His family history included his mother having a stroke at age 60, his father dying early, an uncle dying early, and his brother having a triple bypass before age 50. This case demonstrates that familial or genetic inheritance represents the biggest signal for cardiovascular risk.
