A Comparison of Outcomes with Angiotensin-Converting–Enzyme Inhibitors and Diuretics for Hypertension in the Elderly

Study Design

The study design and recruitment strategies have been published previously.^22-24 In brief, the study was conducted at 1594 family medical practices throughout Australia, with the use of a prospective, randomized, open-label design, with blinded assessments of end points.²⁵

At screening, blood pressure was measured by trained study nurses using a mercury sphygmomanometer in all eligible subjects 65 to 84 years of age.²⁶ Suitable subjects had two subsequent study-entry visits at least one week apart. In subjects who were taking antihypertensive drugs, medication was discontinued under medical supervision. Subjects were required to be free of antihypertensive drugs for at least one week before the study-entry visits.

Criteria for Inclusion and Exclusion

Criteria for inclusion in the study were an average systolic blood pressure, measured at the two study-entry visits while the subject was sitting, of at least 160 mm Hg or an average diastolic blood pressure of at least 90 mm Hg (if the systolic blood pressure was at least 140 mm Hg); the absence of recent cardiovascular events (within the previous six months); and willingness to give informed consent. Criteria for exclusion included any life-threatening illness, contraindication to an ACE inhibitor or diuretic, a plasma creatinine concentration of more than 2.5 mg per deciliter (221 μmol per liter), malignant hypertension, or dementia. Subjects were randomly assigned centrally by telephone to either ACE-inhibitor–based or diuretic-based treatment. Randomization began in April 1995 and was completed in June 1998.

Goals and Treatments

Family practitioners were responsible for the management of antihypertensive therapy, which was to conform to the randomized treatment assignment and the study's blood-pressure goals. The guidelines were based on the aim of achieving a reduction of the systolic blood pressure by at least 20 mm Hg to less than 160 mm Hg, with a further reduction to less than 140 mm Hg if tolerated, and a reduction of the diastolic blood pressure by at least 10 mm Hg to less than 90 mm Hg, with a further reduction to less than 80 mm Hg if tolerated.²⁴ The ACE inhibitor enalapril and the diuretic hydrochlorothiazide were recommended as initial therapy; however, the choice of the specific agent and dose was made by the family practitioner.

To achieve the blood-pressure goals, the addition of beta-blockers, calcium-channel blockers, and alpha-blockers was recommended in both groups.²⁴ Blood pressure was recorded annually by study nurses and at each patient visit by the general practitioner, using routine mercury sphygmomanometry. Case records, hospital notes, and death certificates were reviewed by study nurses for documentation of end points every six months throughout the study.

End Points

The primary end point was all cardiovascular events or death from any cause. Both initial and subsequent fatal and nonfatal cardiovascular events were included. Cause-specific cardiovascular events included the following: coronary events, including myocardial infarction, sudden or rapid death from cardiac causes, other deaths from coronary causes, or coronary events associated with therapeutic procedures involving the coronary arteries; other cardiovascular events, including heart failure, acute occlusion of a major feeding artery in any vascular bed other than cerebral or coronary, death from noncoronary cardiac causes, dissecting or ruptured aortic aneurysm, or death from vascular causes; and cerebrovascular events, including stroke and transient ischemic attacks. An end-point committee whose members were unaware of the treatment-group assignments adjudicated all potential end points.

Approval, Support, and Conduct of the Study

The protocol was approved by the ethics committee of the Royal Australian College of General Practitioners and conducted in accordance with the Helsinki Declaration.²⁷ All subjects gave written informed consent. The study is a project of the High Blood Pressure Research Council of Australia that was initiated, designed, and conducted by the investigators. Although it was funded by a joint venture of the Commonwealth Government of Australia, the National Health and Medical Research Council, Merck Sharp & Dohme, and academic institutions,²⁸ all data analysis and writing were performed independently by the publications committee, without the involvement of representatives of Merck Sharp & Dohme.

Statistical Analysis

Three thousand subjects were required in each group for the study to achieve a power of 90 percent to detect a 25 percent difference between the treatment groups in the rate of cardiovascular events during a five-year period, assuming a rate of 21 events per 1000 person-years in the diuretic group⁴ and allowing for a 15 percent loss to follow-up. The management committee decided to stop the trial because the observed total number of events had well exceeded the number required on the basis of the estimate of sample size and because resources became limited as the result of an extension of the recruitment period. No comparison of the treatment groups in terms of data on outcomes was performed before the study was terminated.

Cox regression was used to model multiple times to events, with the treatment-group assignment as the principal predictor.^29,30 An event was defined as any cardiovascular event or death from any cause. Robust estimates of variance were used to allow for the clustering of subjects according to practitioner, and potential confounding by risk factors was explored by analysts who were unaware of changes in P values or of the direction of changes in estimates.³¹ Only age and sex changed estimates substantially and were therefore adjusted for in the model. Cumulative hazard functions were plotted to check for proportional hazards. Simulation methods were used to validate estimates of the hazard ratios and confidence intervals.

The two primary comparisons (all events and any first events) were tested at the 0.05 level of significance. Hazard ratios with 95 percent confidence intervals and two-sided P values are presented. Hazard ratios from secondary comparisons of cause-specific first events and subgroups defined according to sex are also shown with 95 percent confidence intervals and P values unadjusted for multiple testing, in order to facilitate comparisons with results from other studies. However, the significance of these secondary results should be judged cautiously.³² The number needed to treat to avoid one additional event was estimated from survival functions based on the proportional-hazards model.³³ All results are based on intention-to-treat analyses.

Study Subjects

Figure 1. Figure 1. Summary of Screening, Randomization, and Loss to Follow-up.

ACE denotes angiotensin-converting enzyme.

A total of 54,288 subjects presented for the initial screening visit. Fifty-eight percent (31,255) either were currently being treated for hypertension (25,926 subjects [48 percent]) or had untreated blood pressure in the range specified by the eligibility criteria (5329 subjects [10 percent]). A total of 8316 subjects (4682 previously treated subjects and 3634 untreated subjects) had study-entry visits, and 6083 subjects (95 percent of whom were white) were subsequently randomly assigned to the ACE-inhibitor group (3044 subjects) or the diuretic group (3039 subjects) (Figure 1). Subjects were recruited over a 3-year period and were followed for a median of 4.1 years, for a total of 24,702 patient-years of observation. As indicated in Figure 1, all subjects who underwent randomization were included in the final analysis. For subjects who were lost to follow-up monitoring, we used the last available data; vital status was ascertained for all but two subjects.

Base-Line Data

Table 1. Table 1. Base-Line Characteristics of the Subjects.

The two treatment groups were similar in terms of sex, age, blood pressure, body-mass index (the weight in kilograms divided by the square of the height in meters), plasma cholesterol concentration, tobacco and alcohol use, the level of physical activity, and the extent of previous treatment with antihypertensive drugs (Table 1). Eight percent of subjects had previously had a coronary event, 5 percent had previous cerebrovascular disease, and 7 percent had received a diagnosis of diabetes. Mean (±SD) systolic blood pressure at entry was 168±13 mm Hg; mean diastolic blood pressure at entry was 91±8 mm Hg.

Drug Treatments

At randomization, 83 percent of subjects in both treatment groups began to receive the treatment to which they were assigned, with approximately 15 to 16 percent of subjects not receiving immediate treatment. At the end of the study, 58 percent of subjects randomly assigned to the ACE-inhibitor group and 62 percent of those assigned to the diuretic group were still receiving the assigned treatment. Sixty-five percent of the subjects in the ACE-inhibitor group and 67 percent of those in the diuretic group were receiving monotherapy; 6 percent of the subjects in the ACE-inhibitor group and 5 percent of those in the diuretic group were receiving three or more agents. Concomitant antihypertensive medications (sometimes used in combination) included calcium-channel blockers (in 22.9 percent of subjects in the ACE-inhibitor group and 24.9 percent of subjects in the diuretic group), beta-blockers (10.8 percent and 13.7 percent, respectively), and angiotensin-receptor blockers (14.0 percent and 12.4 percent, respectively).

Blood Pressure

Figure 2. Figure 2. Systolic and Diastolic Blood Pressure after Randomization.

The numbers above the curves indicate the numbers of subjects whose blood pressure was measured. ACE denotes angiotensin-converting enzyme.

At year 1, blood pressure had decreased by 20/9 mm Hg in the ACE-inhibitor group and 22/9 mm Hg in the diuretic group; at year 2, it had decreased by 23/10 mm Hg in the ACE-inhibitor group and 24/10 mm Hg in the diuretic group; and at year 5, it had decreased by 26/12 mm Hg in both groups (Figure 2). These were significant and clinically relevant reductions from base-line values. There were no differences between the groups in the change in diastolic blood pressure at any time point. The pattern of blood-pressure reduction with the two treatments was similar among men and among women.

Outcomes

Table 2. Table 2. Primary End Points and Cause-Specific First Events.

The overall rates of all cardiovascular events or death in the two treatment groups are shown in Table 2. The hazard ratio for all cardiovascular events or death from any cause among subjects in the ACE-inhibitor group as compared with those in the diuretic group was 0.89 (95 percent confidence interval, 0.79 to 1.00; P=0.05); in other words, there was an 11 percent reduction in the total burden of cardiovascular events or death from any cause. The difference between treatment groups appeared early and remained consistent throughout the duration of the study. From a clinical perspective, 32 subjects of either sex in this age group or 23 men would need to be given ACE-inhibitor–based therapy in order to prevent one additional first cardiovascular event or death within the first five years after treatment began.

Figure 3. Figure 3. Primary End Points among All Subjects, Male Subjects, and Female Subjects.

ACE denotes angiotensin-converting enzyme, and CI confidence interval.

There were almost twice as many events in male subjects (907 events) as in female subjects (524 events). The beneficial effects of ACE-inhibitor treatment were more evident in male subjects, among whom there was a 17 percent reduction in the rates of both all cardiovascular events and first cardiovascular events (hazard ratio for both end points, 0.83 [95 percent confidence interval, 0.71 to 0.97]; P=0.02) (Figure 3). Among female subjects, the hazard ratio for all cardiovascular events and first cardiovascular events was 1.00 (95 percent confidence interval for all events, 0.83 to 1.21; 95 percent confidence interval for first events, 0.83 to 1.20; P=0.98 for both comparisons). The P value for the interaction between sex and treatment-group assignment was 0.15 for all cardiovascular events or death from any cause and 0.14 for first cardiovascular events.

The hazard ratio for all first cardiovascular events in the ACE-inhibitor group as compared with the diuretic group was 0.88 (95 percent confidence interval, 0.77 to 1.01; P=0.07); this ratio represents a 12 percent reduction over the study period (Table 2). There was no significant difference between treatments in terms of the rate of first coronary events, but there was a reduction in the rate of first myocardial infarctions in the ACE-inhibitor group: the adjusted hazard ratio was 0.68 (95 percent confidence interval, 0.47 to 0.98; P=0.04).

Table 3. Table 3. Cause-Specific First Events (Fatal and Nonfatal).

There was no significant difference between the two treatment groups in the rates of fatal cardiovascular or noncardiovascular events (Table 3). The rates of cause-specific fatal events did not differ significantly between the treatment groups, with the exception of the rate of fatal strokes, which was higher with ACE-inhibitor treatment (adjusted hazard ratio, 1.91 [95 percent confidence interval, 10.4 to 3.50]; P=0.04).

There was a 14 percent reduction in the rate of first nonfatal cardiovascular events with ACE-inhibitor treatment (adjusted hazard ratio, 0.86 [95 percent confidence interval, 0.74 to 0.99]; P=0.03) and a 32 percent reduction in the rate of first nonfatal myocardial infarctions (adjusted hazard ratio, 0.68 [95 percent confidence interval, 0.47 to 0.99]; P=0.05) (Table 3). There was no significant difference between treatments in terms of any other first nonfatal cardiovascular events. As with the main outcomes of the study, differences between treatment groups in cause-specific fatal and nonfatal events were observed only among male subjects.

Our study has demonstrated that outcomes are better when hypertension in the elderly is treated with an ACE inhibitor than when it is treated with a diuretic agent, with the difference being observed primarily among male subjects. In contrast to other recent trials in the elderly, the subjects in this trial were relatively healthy and active and, overall, had few previous cardiovascular events; one would therefore expect the benefit to be smaller than that found in the other trials, but the results should be more generally applicable to elderly populations. The benefit was a reduction in the rate of total cardiovascular events or death from any cause, with a particular reduction in the rate of nonfatal events. There was also a reduced likelihood of a first cardiovascular event or death.

Since we conducted the study in the family-practice setting, our results reflect the probable effects among relatively healthy elderly persons with hypertension in typical care settings. For example, 15 to 16 percent of subjects in both groups did not immediately begin receiving medication, because the family practitioner and the patient preferred to delay treatment. Faced with an elderly hypertensive patient with blood pressure just above 140/90 mm Hg (satisfying the criteria for study entry), a primary care physician may choose not to begin treatment immediately despite established evidence of benefit. However, all but 3 to 4 percent of subjects were treated during the study. The finding that approximately 60 percent of subjects continued to receive the treatment to which they were assigned for the duration of the study is consistent with findings in other trials focused on hypertension in elderly subjects and suggests what is likely to happen in practice.^4,7,15

Three other published studies have compared ACE-inhibitor–based therapy for hypertension with conventional treatment: the Swedish Trial in Old Patients with Hypertension-2 (STOP-2) study,¹⁵ the Captopril Prevention Project (CAPPP),¹⁶ and the United Kingdom Prospective Diabetes Study (UKPDS).³⁴ The results of these studies are consistent with our findings, but our trial also demonstrates differences of a clinically and statistically relevant magnitude. The design of the trial, the entry criteria, the definition of end points, and the alpha error are factors that may have contributed to the differences between our findings and those of other studies. Although a prospective meta-analysis has concluded that “there were no detectable differences between randomized groups in the risks of any of the outcomes studied,”¹⁹ our study and the Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT)³⁵ will be included in the next cycle of this meta-analysis, which will provide a more definitive comparison of outcomes with ACE-inhibitor–based and diuretic-based regimens.^19,36,37

The observation in our study that the relative benefits of an ACE-inhibitor–based regimen were restricted to men is of interest but should be interpreted with caution, since it represents a post hoc analysis of the data and requires confirmation. The observation that the rate of events among male subjects was almost twice that among female subjects is highly consistent with current data on morbidity and mortality.³⁸ Men have a higher cardiovascular risk than women, and ACE-inhibitor treatment may be of particular advantage in subjects with high cardiovascular risk because of factors that influence the atherosclerotic process, such as stability of plaque and endothelial function.³⁹ This possibility is consistent with results from the HOPE trial showing that ACE inhibitors are beneficial in subjects with high cardiovascular risk, despite minimal change in blood pressure.²⁰ Other possible mechanisms include the absence of any adverse effect on circulating lipids,^12,13 reduction of left ventricular hypertrophy,¹¹ greater likelihood of survival in the presence of cardiac failure,⁹ reduced left ventricular function,⁴⁰ enhanced insulin sensitivity,¹³ and preservation of the glomerular filtration rate.^41-43 Substudies of our study concerning ambulatory monitoring of blood pressure, left ventricular hypertrophy, and vascular compliance may provide evidence clarifying the mechanisms of the putative benefit of ACE-inhibitor therapy beyond its effect on blood pressure.

The reason for discrepant observations concerning the relation between ACE-inhibitor treatment and cause-specific end points — with a greater likelihood that a stroke will be fatal but a lower likelihood of myocardial infarction — is not obvious. An indication that the benefit of treatment does relate to the reduction of the effects of angiotensin II comes from the results of the LIFE study,²¹ which demonstrated a reduction in cardiovascular events or death from cardiovascular causes of 13 percent (95 percent confidence interval, 2 to 23 percent) with losartan as compared with atenolol, despite an equivalent reduction in blood pressure.

In conclusion, in elderly subjects with hypertension, particularly among male subjects, ACE-inhibitor–based therapy resulted in an outcome advantage over a diuretic-based regimen, despite similar reductions in blood pressure. This finding was observed in family practices, where most elderly persons with hypertension receive their care. The question of whether the relative benefit of beginning treatment with an ACE-inhibitor–based regimen is confined to men requires examination in large, ongoing trials.
