Proportion of patients with isolated systolic hypertension who have burned-out diastolic hypertension.

In a community survey of 3242 subjects, 1663 did not initially have isolated systolic hypertension (ISH) and were re-screened an average of 8 years later. ISH developed in 53 (22%) of untreated patients with previous diastolic hypertension. Similarly, 8% of subjects with transient hypertension and 8% of normotensive controls developed ISH.

Survival of hypertensive subjects identified on screening: results for sustained and unsustained diastolic hypertension.

Casual readings of blood pressure predict mortality and may reflect either the risk of sustained hypertension, additional components of 'white coat' hypertension or variable blood pressure. This study investigated mortality in 442 men and 360 women with a diastolic pressure (Phase IV) of 90 mmHg and over, unsustained on two subsequent monthly visits, followed for an average of 11 years and compared with a matched control cohort with an initial diastolic pressure (DBP) of less than 90 mmHg. Subjects were identified between 1975 and 1979 by screening 28,257 subjects aged 18-65 years on the lists of general practitioners in seven practices in the United Kingdom.

A randomised comparative trial of nicardipine versus amiloride and hydrochlorothiazide in mild to moderate hypertension. A report from the General Practitioner Hypertension Study Group.

In 1984 the General Practitioner Hypertension Study Group undertook a rescreening of their patient population, looking for patients who still had untreated mild to moderate essential hypertension. Suitable patients were entered into a clinical trial comparing the safety and efficacy of nicardipine (a calcium antagonist) and amiloride + hydrochlorothiazide (HCTZ) (moduretic). The study included one year of long-term follow-up.

Search for possible CNS depressant compounds: Part II. Synthesis of some new 1-(2'-methoxy-4'-nitrophenyl)-2-phenyl-4-substituted arylidene-5-imidazolones as CNS depressants.

Some new 1-(2'-methoxy-4'-nitrophenyl)-2-phenyl-4-substituted benzylidene, furylidene and naphthylidene-5-imidazolones have been synthesized and tested on their CNS. anticonvulsant and analgesic activities in albino mice. At a dose of 200 mg/kg they displayed CNS depressant properties producing ataxia, decrease in spontaneous motor activity and loss of righting reflex.
