Recent trials in hypertensive patients with type 2 diabetes reveal important differences in the risk for major cardiovascular events when individual agents are compared. In the Fosinopril Amlodipine Cardiovascular Events Trial (FACET), 380 patients with hypertension and type 2 diabetes were randomized to fosinopril or amlodipine and followed for up to 3.5 years to assess effects on serum lipids. Although both agents effectively controlled blood pressure, amlodipine caused a significantly greater decrease in systolic pressure. At the end of the trial, serum cholesterol, high-density lipoprotein cholesterol, triglycerides, HbA1c, serum glucose, plasma insulin, serum creatinine, and microalbuminuria were similar in both groups. The patients randomized to fosinopril were significantly less likely to experience the prospectively defined combined outcome of acute myocardial infarction (MI), hospitalized angina, or stroke compared to those randomized to amlodipine (RR 0.49; 95% CI 0.26-0.95). In the Appropriate Blood pressure Control in Diabetes (ABCD) trial, 470 patients with hypertension and type 2 diabetes who were randomized to long-acting nisoldipine had an adjusted sevenfold increased risk for acute MI compared to those randomized to enalapril (RR 7.0; 95% CI 2.3-21.4). In the Multicenter Isradipine Diuretic Atherosclerosis Study (MIDAS) trial, the patients with hypertension and above the median of HbA1c (> or =6.7%) randomized to isradipine had a threefold increased risk for major cardiovascular events compared to those randomized to hydrochlorothiazide (RR 2.81; 95% CI 1.09-7.26). These findings are supported by several observational studies. Therefore, evidence is emerging that angiotensin-converting enzyme inhibitors and low-dose diuretics may be more effective than calcium antagonists for prevention of cardiovascular events in hypertensive patients with diabetes or impaired glucose control.

Macrovascular disease is the major cause of mortality in persons with type 2 diabetes mellitus, and hypertension is an important factor contributing to this high prevalence. High blood pressure is about twice as common in persons with diabetes mellitus as in those without. Up to 75% of diabetes-related cardiovascular complications are attributed to hypertension. These observations are part of the rationale for recommendations for more aggressive lowering of blood pressure (to < 130/85 mm Hg) in persons with coexistent diabetes and hypertension. This may require therapy with a combination of antihypertensive agents. The Fosinopril versus Amlodipine Cardiovascular Events Trial (FACET), discussed herein, supports the case for combination therapy with an angiotensin-converting enzyme (ACE) inhibitor and a calcium antagonist in diabetic patients with hypertension.

The results of 2 recently published studies have been interpreted as suggesting that calcium antagonists are unsafe for the management of hypertension in patients with diabetes. These 2 studies, the Fosinopril versus Amlodipine Cardiovascular Events Randomized Trial (FACET) and Appropriate Blood Pressure Control in Diabetes (ABCD), showed that angiotensin-converting enzyme (ACE) inhibitors may be preferable to calcium antagonists for managing hypertension in diabetic patients; they do not, however, show any harm attributable to calcium antagonists. Indeed, results of the FACET study suggest that the combination of an ACE inhibitor and a calcium antagonist is effective antihypertensive therapy. This suggestion is supported by findings in the Systolic Hypertension in Europe (Syst-Eur) Study, which revealed outstanding benefits of either a calcium antagonist alone or a calcium antagonist combined with an ACE inhibitor among diabetic patients with hypertension. The premature termination of the hypertensive arm of the ABCD study was puzzling because, although 2 of 13 subgroups of 1 of the 5 possible secondary endpoints in this part of the trial were apparently favorably affected by the use of the ACE inhibitor rather than the calcium antagonist, such a finding was compatible with chance alone. If the results of the FACET and ABCD studies are considered in the context of the best available data arising from large randomized controlled trials, one may conclude that calcium antagonists are not harmful or contraindicated in hypertensive patients with diabetes and that the combination of an ACE inhibitor and a calcium antagonist is effective for the management of hypertension in diabetic patients.

Recent trials have linked calcium antagonists with adverse cardiovascular events in hypertensive patients with diabetes. A closer examination of these trials (in particular the Appropriate Blood Pressure Control in Diabetes [ABCD] trial and the Fosinopril Versus Amlodipine Cardiovascular Events Trial [FACET]) reveals a lack of data from which to draw conclusions of harm. In fact, based on the results of these trials and the recent Hypertension Optimal Treatment (HOT) Trial, one may conclude that the combination of a calcium antagonist with an ACE inhibitor is a rational therapeutic choice in patients with coexisting hypertension and diabetes.

Angiotensin converting enzyme inhibitors (ACE-I) are a mainstay for the treatment of heart failure, and of diabetic microalbuminuria. Recently ACE-I have been found to decrease plasma levels of circulating vascular cell adhesion molecule-1 (cVCAM-1) in patients with congestive heart failure. As increased cVCAM-1 levels are pathognomonic for diabetics with microangiopathy, we investigated the effects of ACE-I on plasma levels of cVCAM-1, intercellular adhesion molecule (cICAM-1), and cE-selectin in microalbuminuric diabetics. In addition, the effects of ACE-I on plasma levels of plasminogen activator inhibitor (PAI-1) and of tissue plasminogen activator (TPA) were studied. Fosinopril (10 mg/day) was administered over 12 weeks to 11 microalbuminuric patients with non-insulin-dependent diabetes mellitus (NIDDM). As expected, baseline plasma concentrations of cE-selectin, cICAM-1, and cVCAM-1 were markedly higher in patients than in healthy control subjects (n = 82; P < .001). PAI-1 levels in NIDDM were similar to those in control subjects, whereas TPA levels were about 25% lower in patients than in control subjects (P = .013). Serum levels of cVCAM-1 decreased by -19% (CI: -25% to -13%) after treatment with fosinopril (P = .003) and were no longer different from those of the control group. In contrast, plasma levels of cE-selectin, cICAM-1, PAI-1, and TPA were unaffected. As expected microalbuminuria decreased by -44% (CI: -65 to -22; P = .004). In conclusion, fosinopril lowered cVCAM-1 levels along with microalbuminuria in NIDDM. This may represent a novel mechanism of action of ACE-I in diabetes-associated endothelial dysfunction. Whether decreased VCAM-1 expression is responsible for the observed reduction in microalbuminuria, deserves further investigation.

Recent trials have helped to clarify indications for the initial pharmacological therapy of hypertension. Both the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC VI) and World Health Organization-international Society of Hypertension (WHO-ISH) recommendations should be revised. The more recent trials indicate that: (1) diuretics and beta-blockers appear to be as effective in reducing overall morbidity/ mortality as other agents (Swedish Trial in Old Patients with Hypertension [STOP-2], United Kingdom Prospective Diabetes Study [UKPDS], Intervention as a Goal in Hypertension Treatment [INSIGHT], Nordic diltiazem [NORDIL]); (2) the use of an a-blocker results in more cardiovascular events, especially congestive heart failure, when compared with a diuretic (Antihypertensive Therapy and Lipid Lowering Heart Attack Trial [ALLHAT]); (3)the use of an angiotensin-converting enzyme (ACE) inhibitor results in fewer myocardial infarctions and episodes of heart failure than calcium channel blockers in the elderly and in diabetic patients (Fosinopril vs. Amlodipine Cardiovascular Events Randomized Trial [FACET], Appropriate Blood Pressure Control in Diabetes [ABCD], STOP-2) - other data (Captopril Prevention Project [CAPPP]) suggest that the use of an ACE inhibitor is preferred in diabetic patients; (4) overall cardiovascular events are similar with calcium channel blockers compared with a diuretic - however, there are fewer strokes with non-dihydropyridine calcium channel blockers (NORDIL) and a trend towards an increase in heart failure and myocardial infarctions with either a dihydropyridine or non-dihydropyridine calcium channel blockers compared with a diuretic (INSIGHT, NORDIL); (5) angiotensin receptor blockers (ARBs) will decrease proteinuria and slow progression of renal disease in type 2 diabetic patients when compared with regimens that do not include an ARB or an ACE inhibitor (Reduction of Endpoints in NIDDM with the Angiotensin II Antagonist Losartan [RENAAL], Irbesartan Type II Diabetic Nephropathy Trial [IDNT], Irbesartan Type II Diabetes with Microalbuminuria [IRMA Il]). The debate over initial therapy may be moot. High-risk hypertensive patients should probably be treated initially with combination therapy, one of which should be a diuretic. The use of diuretics and beta-blockers as well as ACE-inhibitors alone or with a diuretic should be considered as initial therapy (a change from JNCVI). Alpha-blockers should be reserved for special situations, i.e. prostatic hypertrophy (in contrast to WHO-ISH recommendations). An ACE-inhibitor or ARB, usually along with a diuretic, can be considered as preferred therapy in hypertensive diabetic patients. Some data suggest equal or greater reduction in strokes with a calcium channel blocker than other medications.

Hypertension and diabetes are commonly found conditions, which predispose to premature cardiovascular morbidity and mortality. A strong consensus has emerged in support of aggressive blood pressure reduction in order to forestall the almost inevitable complications that follow from being a hypertensive diabetic. As of yet though it is not clearly determined as to what represents the best class(es) of antihypertensive medications to effect such blood pressure reduction. In this regard, considerable debate has arisen as to the cost/benefit ratio of dihydropyridine calcium channel blockers in the hypertensive diabetic. Although studies such as the Fosinopril vs. Amlodipine Cardiovascular Events Trial and the Appropriate Blood Pressure Control in Diabetes study would seem to argue against the use of dihydropyridine calcium channel blockers in the diabetic hypertensive, other studies such as the subset analyses of the Syst-Eur and the Syst-China and the Hypertension Optimal Treatment study provide almost compelling evidence for the safety of low to moderate doses of a dihydropyridine calcium channel blockers in this population. Safety issues of dihydropyridine calcium channel blockers will remain unresolved until the release of the Antihypertensive and Lipid Lowering Study to Prevent Heart Attack results at which time a resolution to this question should be forthcoming.

Renal dysfunction is an independent risk factor of chronic cardiac failure (CCF) and death due to this disease. CCF patients are elderly patients with diabetes mellitus, arterial hypertension and long-term chronic cardiac insufficiency. CCF patients do not often have left ventricular systolic dysfunction, renal affection is not associated with low ejection syndrome. Renal affection in CCF is primarily caused by activation of the system rennin-angiotensin, inflammation, disturbed bioavailability of nitric oxide, hyperactivation of the sympathetic nervous system. ACE inhibitors correct pathophysiological disorders of renal flow in CCF. Fosinopril shows the highest efficacy and safety in management of cardiorenal syndrome in CCF patients. Fosinopril can also prevent renal dysfunction in CCF patients.

Optimal blood pressure (BP) targets are still controversial in end-stage renal disease. Recent data have highlighted shortcomings of the usual BP hypothesis in other patient populations and emphasized the importance of visit-to-visit variability of BP in predicting cardiovascular events. The Fosinopril in Dialysis Study failed to demonstrate the efficacy of 2-year angiotensin-converting enzyme inhibition with fosinopril versus placebo in 397 hemodialysis patients with left ventricular hypertrophy but provided an opportunity to assess the influence of BP variability on cardiovascular events. The primary end point was the occurrence of a composite of cardiovascular death, nonfatal myocardial infarction, unstable angina, stroke, revascularization, hospitalization for heart failure, and resuscitated cardiac arrest. The variations in BP throughout the 17 visits were assessed by within-patient overall variability of systolic, diastolic, and pulse pressures between adjacent readings, by within-patient overall variability of systolic/diastolic/pulse pressures, and the residual of the linear fit. Compared with our previous predictive model of cardiovascular events occurrence based on stroke, peripheral arterial disease, coronary artery disease, diabetes mellitus, left ventricular mass, and age (which exhibited similar coefficients herein), the percentage of explained variance improved by 30.1% (R(2)=0.141-0.183) when adding the coefficient of variation of within-patient overall variability of systolic BP. Usual BP parameters were neither cardiovascular events predictors nor correlated to BP variability. Visit-to-visit BP variability was extremely high in hemodialysis patients compared with other populations and a major determinant of cardiovascular events. Such assessments should be prioritized for testing prevention strategies in end-stage renal disease.

As the most common and severe complication of diabetes, diabetic nephropathy (DN) has been known to be related with angiotensin converting enzyme inhibitor (ACEI), which can reduce proteinuria and protect renal function. This study analyzed the effect of ACEI analog-fosinopril-on the expression of chemerin and vascular epithelial growth factor (VEGF), in an attempt to reveal the mechanism of ACEI analog on renal protection. A total of 45 SD rats were induced by sreptozotocin for diabetes and were given fosinopril via intragastric cannulation for 12 weeks. After sacrifice, serum and renal chemerin and VEGF contents were quantified by enzyme linked immunosorbent assay (ELISA) and Western blot method, in addition to biochemical laboratory examinations. In diabetic model rats, blood glucose, creatinine, urea nitrogen, 24-hour urinary protein, chemerin and VEGF protein contents were all significantly elevated when compared to those in control group (P<0.05). After fosinopril treatment, blood creatinine, urea nitrogen, 24-hour urinary protein, Chemerin and VEGF protein concentrations were significantly depressed (P<0.05 compared to model group). Positive relationships existed between renal chemerin, VEGF and urea protein levels. Fosinopril may protect renal tissues in diabetes by suppressing chemerin and VEGF protein expression.
