Despite a marked reduction in cardiovascular morbidity and mortality, treated hypertensive patients remain at increased risk of coronary artery disease and its complications compared with untreated normotensive subjects. Mild hypertension is often associated with other, usually chronic, diseases. The failure of first-line antihypertensive therapy to deal adequately with concomitant disease and associated therapy might account for the poor improvement in the cardiovascular prognosis. This possibility has been addressed in an ongoing trial of novel design, the Perindopril Therapeutic Safety Study, a multicenter, double-blind, randomized and placebo-controlled trial to determine the safety, efficacy, and interaction of angiotensin-converting enzyme (ACE) inhibition with eight of the most common concomitant diseases and their therapies. A total of 480 male and female patients (60 per disease group) aged 30-70 years, with a diastolic pressure of 90-104 mm Hg, were included after a 3-week placebo run-in if they satisfied standard criteria for any of the following: hyperlipidemia, type II diabetes, ischemic heart disease, cardiac arrhythmia, peripheral arterial disease, nephropathy with proteinuria, chronic obstructive lung disease, or rheumatoid arthritis. Of these, 460 patients have completed the 6-week double-blind phase (comprising two assessments, at 3 and 6 weeks), and are currently undergoing assessments every 3 months over a 1-year follow-up period. The end points include the incidence of progression or improvement in concomitant disease, the incidence of positive or negative interaction between ACE inhibition and concomitant therapy, change in blood pressure, adverse biochemical and hemodynamic reactions, self-reported side effects, and quality of life indices. Interim results for the 6-week double blind phase will shortly be available. However, the desirability and feasibility of conducting a study according to this novel design have already been proved.

Thirty-six hypertensive patients with impaired renal function entered a long-term study to assess the safety of perindopril. There were 28 men and 8 women of mean age 57.1 +/- 2.0 years (mean +/- SEM). The duration of documented hypertension was 7.3 +/- 1.2 years. Perindopril was given orally in single daily doses. The initial dosage was chosen according to the degree of renal function impairment: 29 patients received 4 mg o.d. [creatinine clearance (Clcr), 42.2 +/- 3.2 ml.min-1] and 7 patients received 2 mg o.d. (Clcr, 22.3 +/- 3.1 ml.min-1). Patients in whom blood pressure was not controlled had their dose doubled and then, if necessary, an additional diuretic therapy was added at subsequent visits. Six patients were withdrawn for adverse events (myocardial infarction, pneumonia, leucopenia in a patient who had lupus, diabetes mellitus, skin rash, epigastric pain), two patients were withdrawn for poor compliance, and three for personal convenience. The mean duration of treatment was 10.2 months with a range of 3-12 months (excluding one patient who died from myocardial infarction in the first days of the study and was not included in the analysis). Systolic and diastolic blood pressure decreased significantly (from 170.5/100.6 +/- 3.4/1.8 mm Hg to 151.8/88.8 +/- 3.0/1.7 mm Hg, n = 35, p less than 0.001). Baseline and final values of plasma creatinine (from 223.7 +/- 22.7 to 234.7 +/- 28.5 mumols/l), Clcr (42.5 +/- 3.2 to 45.7 +/- 4.6 ml.min-1), and kalemia (from 4.4 +/- 0.1 to 4.7 +/- 0.1 mmol/L) were not statistically different.(ABSTRACT TRUNCATED AT 250 WORDS)

Cardiovascular risk factors such as hypertension, diabetes, and dyslipemia are associated with an impaired endothelium-dependent vasodilation. In patients with type 2 diabetes mellitus, these risk factors are frequently clustered. We investigated whether long-term treatment with the angiotensin-converting enzyme (ACE) inhibitor perindopril can improve endothelium-dependent vasodilation in this particular group of patients. We selected 10 patients with type 2 diabetes and hypertension (age 59.4 +/- 3.2 years, body mass-index 29.7 +/- 1.5 kg.m-2, blood pressure 169 +/- 6/92 +/- 1 mm Hg, total cholesterol 6.6 +/- 0.3 mM). Using venous occlusion plethysmography, we recorded the increases in forearm blood flow (FBF) in response to three vasodilator stimuli: (a) 5 min of forearm ischemia, (b) infusion of the endothelium-dependent vasodilator methacholine (Mch) into the brachial artery (0.03, 0.3, and 1.0 micrograms/min/100 ml), and (c) intraarterial infusion of the endothelium-independent vasodilator sodium nitroprusside (SNP 0.06, 0.2, 0.6 microgram/min/100 ml). This procedure was repeated after 6 months of treatment with perindopril 4-8 mg/day. Forearm vascular resistance (FVR) was calculated by the quotient of the mean arterial pressure (MAP) and the FBF. Perindopril reduced blood pressure (BP) by 19/10 mm Hg (p < 0.05) and increased baseline FVR, but improved neither the maximal percentage decrease in vascular resistance induced by Mch (from -80 +/- 2 to -82 +/- 2%) nor that induced by SNP (from -73 +/- 3 to -72 +/- 3%). Perindopril decreased the FVR reached after the ischemic stimulus from 6.5 +/- 1.2 to 4.8 +/- 0.6 U (p < 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

A multicenter, double-blind, randomized, and placebo-controlled trial, the Perindopril Therapeutic Safety Study (PUTS), was designed to assess the interaction between angiotensin-converting enzyme (ACE) inhibition and the diseases and therapies commonly found associated with mild hypertension. A total of 480 male and female patients aged 30-70 years with a diastolic pressure of 90-104 mm Hg were included after a 3-week placebo run-in if they satisfied standard criteria for any of the following: hyperlipidemia, type II diabetes, ischemic heart disease, cardiac arrhythmia, peripheral arterial occlusive disease, nephropathy with proteinuria, chronic obstructive lung disease or treatment with nonsteroidal anti-inflammatory drugs (NSAIDs). At the end of the placebo run-in period, patients were randomly assigned to either placebo or perindopril 4 mg once daily. A total of 460 patients completed the 6-week double-blind phase, comprising 3 assessments at 1, 3, and 6 weeks. In this report, the principal results obtained in 5 disease groups (hyperlipidemia, type II diabetes, ischemic heart disease, nephropathy with proteinuria, and NSAID treatment) will be reported. A total of 269 patients belonging to one of the aforementioned 5 disease groups completed the double-blind phase of the study and were included for statistical evaluation. In the perindopril group, systolic and diastolic blood pressures decreased significantly more than in the placebo group, and a sitting diastolic blood pressure of 90 mm Hg was achieved in 65% of patients in the perindopril group and 30% of patients in the placebo group. The incidence of symptoms spontaneously reported by the patients was low: 2 patients of the perindopril group complained of cough.(ABSTRACT TRUNCATED AT 250 WORDS)

Efficacy and acceptability of perindopril (Coversyl) in general practice were evaluated in 23,460 hypertensive patients (52.9% women) during an open six month trial. Patients had essential mild to moderate hypertension (94 mmHg < supine DBP < 115 mmHg) associated or not with obesity (34%), diabetes (12%), hypercholesterolemia (36%), smoking habits (24%). Mean hypertension duration was 6.5 years, 70 p. cent of patients were 50 to 69 years old and 12 p. cent 70 years old or more. Perindopril was started at 4 mg except in older and patients with renal insufficiency (2 mg). If supine DBP remained > 90 mmHg the dose was doubled up to 8 mg/day, then a thiazide diuretic was added. Monotherapy was held in 90 p. cent of cases all along the study, more than 8 over 10 times at 2 or 4 mg/day. Normalized patients (DBP < or = 90 mmHg) were 69.87 and 95 p. cent respectively at the first, third and sixth month. Mean supine SBP and DBP decrease were 27.3 and 18.0 mmHg. Antihypertensive activity was similar in patients taking psychotrope or non steroidal anti-inflammatory agents and in others, as well as in older (> or = 70 years), diabetics and obeses, however with a significantly more frequent bitherapy in these last three sub-groups. Cough, a well known side effect of ACEI led to withdrawal in only 2.6 p. cent of cases. Withdrawals for side-effect were more frequent in older patients (6.1%), in those taking psychotrope (5.3%) or non steroidal anti-inflammatory agents (6.0%) than in diabetics (4.1%) or the others (4.1%).(ABSTRACT TRUNCATED AT 250 WORDS)

Abundant evidence has accumulated showing that angiotensin converting enzyme (ACE) inhibitors reduce long-term cardiovascular morbidity and mortality rates in patients with heart failure and myocardial infarction. Fewer completed trials have assessed their potential benefits in this regard in hypertensive subjects, but evidence of benefit is beginning to accrue from studies examining patients with hypertension, particularly in the presence of diabetes and after infarction. Ongoing trials of blood pressure (BP) lowering using ACE inhibition fall into three main categories: 1) those comparing ACE inhibitors with older drugs such as diuretics and beta blockers; 2) those examining more aggressive versus less aggressive lowering of BP; and 3) those investigating BP lowering in patients at high risk for a cardiac event. Among those in the last group is the Perindopril Protection Against Recurrent Stroke Study (PROGRESS), which examines the effects of perindopril-based ACE inhibitor therapy in both normotensive and hypertensive patients who have survived a stroke. This trial is particularly important because it serves as a model for studies of BP lowering across a wide range of BP and BP-related conditions.

The angiotensin-converting enzyme inhibitor, perindopril erbumine, has been approved for use in the United States only recently but has been studied extensively worldwide over the last decade. Placebo-controlled trials in a wide range of patients with hypertension, including the elderly, those with isolated systolic hypertension, and those with concomitant diseases such as hyperlipidemia, diabetes, cardiac arrhythmia, peripheral arterial occlusive disease, nephropathy with proteinuria, and chronic obstructive pulmonary disease, have shown that perindopril is highly effective in lowering both systolic and diastolic blood pressure (BP). Studies in which BP has been monitored for 24-hour intervals show that perindopril (1) has a gradual onset of action, (2) provides smooth BP control over its once-daily dosing interval, (3) has a trough-peak ratio of about 1, and (4) maintains its antihypertensive efficacy despite missed doses. Perindopril increases arterial compliance and reverses left ventricular hypertrophy in hypertensive patients. Both of these effects are at least partly independent of its ability to lower BP. Perindopril is safe and well tolerated in patients with hypertension. Rates of adverse events and discontinuation because of such events are low.

The renin-angiotensin system plays an important role in the elevation of asymmetric dimethylarginine (ADMA), an endogenous inhibitor of nitric oxide synthase, in hypertensive patients, so the present study was designed to examine whether angiotensin-converting enzyme (ACE) activity is also involved in the mechanism of ADMA elevation in type 2 diabetes mellitus (NIDDM). A crossover study was performed to determine if ACE inhibition with perindopril (4 mg/day) for 4 weeks decreases serum ADMA concentration and plasma von Willebrand factor (vWF) level (a marker of endothelial injury) in 11 patients with NIDDM. None of the patients was treated with insulin or oral hypoglycemic drugs, and none had major diabetic complications. Before the protocol began, serum ADMA and plasma vWF were significantly higher in the 11 NIDDM patients, when compared with 8 control subjects without diabetes. Perindopril did not affect blood pressure or glucose metabolism, but did significantly decrease serum ADMA and plasma vWF. These results suggest that endothelial injury associated with ADMA elevation may be present even in patients with non-complicated NIDDM, and that increased activity of ACE may be involved in such endothelial dysfunction.

Microalbuminuria in diabetes is a risk factor for early death and an indicator for aggressive blood pressure (BP) lowering. We compared a combination of 2 mg perindopril/0.625 mg indapamide with enalapril monotherapy on albumin excretion rate (AER) in patients with type 2 diabetes, albuminuria, and hypertension in a 12-month, randomized, double-blind, parallel-group international multicenter study. Four hundred eighty-one patients with type 2 diabetes and hypertension (systolic BP > or =140 mm Hg, <180 mm Hg, diastolic BP <110 mm Hg) were randomly assigned (age 59+/-9 years, 77% previously treated for hypertension). Results from 457 patients (intention-to-treat analysis) were available. After a 4-week placebo period, patients with albuminuria >20 and <500 microg/min were randomly assigned to a combination of 2 mg perindopril/0.625 mg indapamide or to 10 mg daily enalapril. After week 12, doses were adjusted on the basis of BP to a maximum of 8 mg perindopril/2.5 mg indapamide or 40 mg enalapril. The main outcome measures were overnight AER and supine BP. Both treatments reduced BP. Perindopril/indapamide treatment resulted in a statistically significant higher fall in both BP (-3.0 [95% CI -5.6, -0.4], P=0.012; systolic BP -1.5 [95% CI -3.0, -0.1] diastolic BP P=0.019) and AER -42% (95% CI -50%, -33%) versus -27% (95% CI -37%, -16%) with enalapril. The greater AER reduction remained significant after adjustment for mean BP. Adverse events were similar in the 2 groups. Thus, first-line treatment with low-dose combination perindopril/indapamide induces a greater decrease in albuminuria than enalapril, partially independent of BP reduction. A BP-independent effect of the combination may increase renal protection.

The objective of the study was to assess, from a health service perspective, whether a systematic program to modify kidney and cardiovascular disease reduced the costs of treating end-stage kidney failure. The participants in the study were 1,800 aboriginal adults with hypertension, diabetes with microalbuminuria or overt albuminuria, and overt albuminuria, living on two islands in the Northern Territory of Australia during 1995 to 2000. Perindopril was the primary treatment agent, and other medications were also used to control blood pressure. Control of glucose and lipid levels were attempted, and health education was offered. Evaluation of program resource use and costs for follow-up periods was done at 3 and 4.7 years. On an intention-to-treat basis, the number of dialysis starts and dialysis-years avoided were estimated by comparing the fate of the treatment group with that of historical control subjects, matched for disease severity, who were followed in the before the treatment program began. For the first three years, an estimated 11.6 person-years of dialysis were avoided, and over 4.7 years, 27.7 person-years of dialysis were avoided. The net cost of the program was 1,210 dollars more per person per year than status quo care, and dialyses avoided gave net savings of 1.0 million dollars at 3 years and 3.4 million dollars at 4.6 years. The treatment program provided significant health benefit and impressive cost savings in dialysis avoided.
