High blood pressure-the silent killer.

Hypertension is an issue of international and national importance. The aetiology of hypertension is conjectural. However, its treatment must be regarded as one of the strongest weapons against coronary artery disease, cerebrovascular episodes and renal failure. Thus therapeutic compliance has become a major problem. Because only a small proportion of the population is receiving treatment a modular system, perhaps a tertiary health system, should be developed. The primary prevention of cardiovascular disease must be the ultimate goal and is clearly our most cost-effective strategy.
