to within normal limits "is the greatest challenge in preventive medicine today," he said.

Patient response to hypertension treatment is notably better in a hospital setting than in "scatter sites," he noted.

At the Harlem Hospital hypertensive unit, 405 patients were treated last year, and made a total of 2,492 visits. Compliance with physicians' instructions was "excellent," he said. Hypertension was controlled in more than 90% of cases.

In CONTRAST, of 4,200 people screened at "scatter sites" in a hypertension-identification program, 32-35% of those screened were recognized as hypertensives, but only 8% complied with instructions for long-term therapy, Dr. Williams said. 

Hormonal profiling simplifies treatment, and for an increasing number of patients, "permits long-term therapy with a single agent," said John H. Laragh, MD, professor of medicine, Columbia U. College of Physicians and Surgeons.

Profiling, combined with the patient's subsequent drug responses, "exposes a role for abnormal renin secretion in the causation of a major fraction of hypertensive disease," Dr. Laragh said.

Renin acts on plasma proteins to produce angiotensin, which in turn initiates renal hypertension through blood-vessel constriction.

A "PROFILE" is constructed from a renin sodium index, consisting of measurements of plasma renin, urinary sodium, and urinary aldosterone. From this, renin levels, degrees of treatment risk, and proper drug selection can be assessed.

Studies indicate that hypertension patients with low renin levels are relatively protected from coronary occlusion and stroke - complications which high-renin-level patients are especially prone to develop, Dr. Laragh said.

Poor blacks, like other poor people, often hesitate to seek medical care early, and thus hypertension "is far advanced when they do," said NMA President Rann.

The VD rate is "rising among all people," he noted, and narcotics addiction "is not getting better."

Most crimes in cities such as his home, Charlotte, N.C., "and in the ghetto are related to drugs," Dr. Rann said. "A lot of kids have the idea that it (addiction) can't happen to them, and they take a chance on it."
