Coronary Risk Factors, II

Summary: Prospects for prevention of atherosclerosis in the young. There appears to be a need to protect our young from an atherogenic way of life. The average male child today has one chance in three of a cardiovascular catastrophe before age 60. Atherosclerosis and the conditions which predispose appear to have their onset in childhood. Correctable precursors of cardiovascular disease have been identified, and their contribution to risk has been estimated not only for adults but for college students as well. An analysis of the combined impact of atherogenic risk factors indicates that they exert greater force early in life than later. Although the optimal time to begin prophylaxis is not established, there is evidence to suggest that measures instituted late in life when lesions are advanced is of only limited value. Prevention of atherosclerosis is best viewed as a family affair since the propensity to disease and contributing factors tend to be shared by family members. It is also difficult to implement effectively preventive measures which include dietary changes, weight control, exercise and restriction of cigarettes for one family member without involving the rest of the family. Optimal levels of the correctable precursors of cardiovascular disease are not established for children. However, the rise in serum lipids, blood pressure, weight and blood sugar observed in transition from childhood to adult life is not inevitable, or desirable. Paediatricians can alter the appalling cardiovascular mortality statistics by not allowing the process or the habits and conditions which promote it to reach an irreversible stage. Cardiovascular disease may well begin in childhood with “medical trivia” such as a tendency to obesity, moderate cholesterol and blood pressure elevations, lack of exercise and the cigarette habit. In some respects a heart attack at age 45 can be regarded as a failure of the paediatrician. Awaiting proof of the efficacy of the indicated prophylactic measures is not acceptable since this will be a long time in coming. We must learn how to correct risk factors effectively in childhood as soon as they appear. We must establish goals based on optimal as distinct from usual levels of risk factors. Paediatricians' resolve about prevention of atherosclerosis in childhood needs to be strengthened and we must develop a sense of urgency about this.
