In the SYST-EUR study, the Vascular Dementia Project run on 3,111 subjects 60 years old and over, with isolated systolic hypertension, has shown that the cognitive status as measured by the MMSE was inversely correlated with systolic blood pressure (p < 0.001) and age (p < 0.001) and positively correlated with the level of education (p < 0.001). It is significantly lower in patients with cardiovascular complications (p = 0.0001). Moderate alcohol consumption is linked to a higher MMSE score in women (p < 0.001) but not in men. In this study, the incidence of dementia is low and significantly related to the baseline value of the MMSE score and further analysis will show the influence of the treatment of systolic hypertension with calcium antagonists as first step on this incidence.

To evaluate, in a cross sectional study, the relationships between cognitive functions and blood pressure in a population of subjects with Alzheimer's disease. In 520 subjects of a survey in a French population with Alzheimer's disease, relationships between the severity of cognitive decline and a history of hypertension or blood pressure level have been searched. Cognitive functioning was assessed with validated neuropsychological tests evaluating cognitive functions and the capacities in the activities of daily living (Mini Mental State Examination (MMSE), Alzheimer's Disease Assessment Scale--Cognitive part (ADAS-Cog), Instrumental Activities of Daily Living (IADL), Activities of Daily Living (ADL), Clinical Dementia Rating (CDR), Global Deterioration Scale (GDS) of Reisberg). In 456 subjects blood pressure was measured during the consultation....

A model was created to extrapolate over a 3-year period the results from placebo-controlled trials together with epidemiological and prevalence data. Costs considered in the model were net societal costs associated with paid and unpaid assistance, general medical consumption and institutional care. The model suggested that delays in cognitive decline and functional dependence due to treatment reduced the time spent in institutional care and the burden on caregivers. Over a 3-year period, total net costs of caring for untreated patients with an initial Mini-Mental State Examination score ranging from 10 to 26 were EUR 53,206 compared with EUR 42,720 for a patient treated with donepezil--an annual cost saving of approximately EUR 3,500 per patient. Cost savings were mainly due to savings ...

This study was carried out in a double-blind, randomized, placebo-controlled design. After 6 weeks of treatment with labetalol (mean dose = 235 +/- 47.5 mg/day), the systolic pressure was lowered from 187 +/- 24 to 145 +/- 28 mmHg (p less than 0.001) and the diastolic pressure from 98 +/- 10 to 82 +/- 9 mmHg (p less than 0.001). Likewise, in the placebo group, both systolic and diastolic pressures were significantly reduced but the changes were significantly greater in the labetalol group, -33 +/- 26 versus -13 +/- 20 mmHg and -14 +/- 10 versus -8 +/- 14 mmHg respectively. Labetalol achieved B.P. control (160/95 mmHg) in 64% of the treated patients, compared to 40% in the placebo group. Two patients on labetalol discontinued their treatment due to side-effects (one bradycardia and one cutaneous reaction) compared with one patient on placebo (cardiac failure). Two other cases in the labetalol group had side-effects (one fatigue and one dizziness) which prevented increasing the treatment as necessary.

A double-blind, randomized, placebo-controlled trial was carried out in 32 subjects aged from 75 to 97 years (mean: 86 years) with blood pressure values equal or superior to 160/90 mmHg. After 8 weeks of treatment with enalapril in doses of 20 to 40 mg/day, the systolic pressure was lowered from 190 +/- 16 to 151 +/- 19 mmHg (P less than 0.0001) and the diastolic pressure from 102 +/- 7 to 85 +/- 11 mmHg (P less than 0.0001). Systolic and diastolic pressures were also significantly reduced in subjects under placebo (from 183 +/- 16 to 165 +/- 21 mmHg, P less than 0.001; and from 101 +/- 9 to 91 +/- 13 mmHg, P less than 0.001, respectively), but the degree of reduction was significantly superior with enalapril (systolic: 39 +/- 25 vs 18 +/- 19 mmHg, P less than 0.005; diastolic: 17 +/- 13 vs 11 +/- 12, P less than 0.001); blood pressure was inferior to 160/90 mmHg in 67% of the s...

In a randomized, double-blind drug versus placebo study involving 34 such patients of mean age 84 years, we observed a 10 p. 100 fall in systolic arterial pressure (p less than 0.01) and a 9 p. 100 fall in diastolic arterial pressure (p less than 0.01) in the perindopril group. The corresponding figures in the placebo group were 5 p. 100 and 4 p. 100 respectively, the difference between the two groups not being significant. The drug was well tolerated, both clinically and biochemically. However, a significant (p less than 0.01) increase in blood potassium level (albeit within normal limits) was observed in the treated group. An open trial conducted in 91 patients (mean age 79.1 years) followed up for 6 years confirmed the acceptability of the drug despite a transient decrease of creatinine clearance recorded in one patient. The effectiveness of perindopril, evaluated less unqu...

Half were treated with hydrochlorothiazide and triamterene and half were given placebo and a second capsule was given and if necessary up to 2 g of methyldopa/day. The measurements in a sample of 157 patients suggested 80-86% compliance rate. A significant blood pressure difference of 25/10 mm Hg was obtained between the groups and maintained during five years of follow-up. The increase in serum creatinine found in the actively treated group was related to the decrease in sitting systolic blood pressure. Changes in serum uric acid correlated with changes in serum creatinine both in the placebo and in the actively treated group. Fasting blood glucose changed significantly in the active treatment group. The balance between this decreased risk on the basis of the blood pressure reduction and the increase produced by the rise in blood glucose and the other treatment effects remains to be determined. The trial continues and more patients are being admitted.

One third of the active treatment group also received 250 mg to 2 g methyldopa daily. After 1 year the active treatment group had an average increase in fasting blood sugar of 2.5 mg/dl compared with an average fall of 1.4 mg/dl in the placebo group (P = 0.01). The increase in blood sugar 1 hour and 2 hours after 50 g oral glucose tended to be greater in the actively treated group but these increases did not achieve statistical significance. The effects of diuretic treatment were established after one year and did not increase further over the next 2 years. Overall there was an increase in fasting blood sugar of 5 mg/dl in the active treatment group which occurred mainly in the first year. The hyperglycaemic effect of diuretics appeared to be partly or wholly related to potassium loss since, in both groups, impairment of glucose tolerance was most marked in those in whom serum potassium decreased. The measures of blood sugar were also positively related to systolic pressure before and after treatment.
