Blood pressure measurements were obtained among 92,074 persons in Milwaukee between 1974 and 1976 by the Milwaukee Blood Pressure Program. Systolic hypertension was more prevalent in young white men than blacks below 25 years of age, was more common in middle-aged blacks than whites, and was equally prevalent among all persons past 65 years. Diastolic hypertension was more prevalent in blacks than whites of all ages. Whereas the prevalence of systolic hypertension in the population increased with age and was present in a majority or near majority of persons past 65 years, the prevalence of diastolic hypertension rose until the sixth decade, after which it declined. Hypertension was primarily of a diastolic variety in young blacks, whereas systolic hypertension was a prominent feature in young whites.

A patient with intractable congestive cardiac failure secondary to renovascular hypertension and severe coronary artery disease was infused with the competitive antagonist of angiotensin II, saralasin acetate. The infusion produced an impressive increase in cardiac output and left ventricular stroke work index in parallel with a striking decrease in the systemic and pulmonary vascular resistance, the coronary resistance, and the myocardial oxygen consumption. It is suggested that angiotensin inhibition may present advantages over other forms of treatment of congestive cardiac failure in selected cases.

A critically ill patient with severe renovascular hypertension following surgical repair of an aortic dissection was treated by percutaneous selective embolization of the ischemic kidney. Correction of the hypertension and subsequent complete recovery of the patient resulted.

Hypertensive crises were reported in three patients with hypertension associated with underlying renovascular occlusive disease during reduction of antihypertensive therapy. In each case, rebound hypertension was observed during clonidine hydrochloride withdrawal. Therapy with propranolol hydrochloride and diuretics had also been discontinued in two of the three patients. This and other reports of rebound hypertension during clonidine withdrawal are contrasted with the absence of reports of this syndrome in the setting of cessation of beta-adrenergic blockade therapy. This suggests that the discontinuation of clonidine therapy was primarily responsible for the hypertensive crises herein described. It is further concluded that rebound hypertension may follow gradual as well as abrupt reduction of clonidine dosage, and that patients with renovascular hypertension may be at greatest risk.

The prognostic value of renal vein and peripheral renin levels was analyzed in 66 patients with unilateral renal artery stenosis who underwent corrective surgery. Patient selection for operation was independent of renin results. Fifty-three percent of those with confirmed renovascular hypertension had renal vein renin ratios less than 2.0, ie, within the 95% confidence limit for the control group of 82 patients with essential hypertension. Thirty-four patients with clearly lateralizing renin data (ipsilateral:contralateral greater than or equal to 1.5 and contralateral:peripheral less than or equal to 1.3) were benefited by operation, but 23 additional patients with nonlateralizing data also benefited. No proposed scheme for renin data analysis detected more than 75% of those with renovascular hypertension. Although lateralizing renin data are highly predictive of operative benefit, nonlateralizing data do not necessarily herald operative failure and should not be dogmatically used to exclude surgical intervention.

In the Hypertension Detection and Follow-up Program, the largest standardized hypertension detection, follow-up, and treatment program to date in the United States, participation rates have been high at all stages. More than 75% of those with suspected hypertension at screening attended follow-up rescreening, and more than 80% of the 5,314 hypertensive patients assigned to program treatment remained active at the end of one year. Differences in participation rates were generally small. To accomplish this, intensive efforts were required to maximize attendance, and the program was shaped to reduce known barriers to initial attendance and long-term adherence. Against the background of a high overall program response rate for all sex-race groups, factors that might be associated with variations in response were examined: age, socioeconomic characteristics, health status, and appointment schedule.

Data from 38,636 pregnant women were studied to determine the best criteria for diagnosing pregnancy hypertension based on the constellation of clinical factors yielding poorest perinatal and long-term results to the offspring. It was found that the combination of maximum diastolic blood pressure and maximum proteinuria, as observed during the interval 28 weeks to term, provided the closest correlation with outcome. This information offered an objective means for establishing a classification of hypertension-hypotension in late pregnancy.

During the years 1974 and 1975 at our institution, 587 patients who had suffered previous myocardial infarctions underwent anesthesia and surgery. Thirty-six (6.1%) had a reinfarction and 25 (69%) died. Patients operated on within three months of the previous infarction had a 27% reinfarction rate. This decreased to 11% if the infarct had occurred three to six months previously and stabilized at 4% to 5% if the interval was more than six months. Risk factors associated with significantly increased reinfarction rates included preoperative hypertension, intraoperative hypotensive episodes, and noncardiac thoracic or upper abdominal operations of more than three hours' duration. Time under anesthesia was strikingly correlated with reinfarction rates in the entire group. Postoperative intensive care unit admission did not significantly affect the reinfarction rate, nor did diabetes, angina, patient age or sex, or site of the previous myocardial infarction.

Plasma 11-deoxycorticosterone levels were manyfold elevated in three adult patients with hypertension and elevated urinary excretion levels of 17-ketosteroids but without Cushing's syndrome. Dexamethasone therapy resulted in suppression of these steroids and in improvement of blood pressure in two of the patients. A partial adrenal 11beta-hydroxylase deficiency appears to best explain these findings.

Interviews with a probability sample of 617 adults in the Chicago area indicated widespread lack of information about major probable causes of heart attacks in persons younger than 60 years: 28% named cigarette smoking, 21% named high blood pressure, and 13% named cholesterol or fat in the diet or blood. Half did not name any of these risk factors, and only 1% named all three. Although three fourths believed that heart attacks are preventable, few named specific behaviors that would effectively reduce risk factors other than smoking. Sustained community-wide educational programs about reducing coronary risk factors are clearly needed and can be effective.
