Numerous pharmacologic agents are capable of lowering the blood pressure of hypertensive patients; however, each drug has a characteristic side effect profile and effect on cardiac performance. In this study, the hemodynamic effects of the angiotensin converting enzyme inhibitor fosinopril were assessed at rest and at peak upright bicycle exercise by first-pass radionuclide cineangiography in 12 patients with essential hypertension. Fosinopril reduced blood pressure at rest in the seated position from 152/101 to 131/85 mm Hg (P less than .01) and at peak exercise from 206/103 to 184/91 mm Hg (P less than .01). Fosinopril therapy was associated with an increase in stroke volume and cardiac output and a decrease in systemic vascular resistance at rest and during peak exercise. Both peak ejection rate and peak filling rate increased significantly at rest during fosinopril therapy. The unique cardiotropic response to fosinopril may reflect its effects on the myocardial renin-angiotensin system, and suggests that this agent may offer a therapeutic advantage compared with other angiotensin converting enzyme inhibitors.

Fosinopril is the prodrug of the active diacid ACE inhibitor fosinoprilat. In patients with heart failure, fosinopril reduces pulmonary capillary wedge pressure, mean arterial blood pressure, mean right atrial pressure and heart rate, and increases stroke volume index and cardiac index. The drug has compensatory dual elimination routes via renal and hepatic systems and accumulates to a lesser extent than enalapril and lisinopril in patients with chronic renal insufficiency with or without heart failure. Comparative studies of 3 or 6 months' duration with fosinopril 10 to 40 mg/day have demonstrated clinical efficacy significantly superior to that of placebo in patients with heart failure [mostly New York Heart Association (NYHA) functional class II or III]. Fosinopril treatment consistently increased exercise duration and improved heart failure symptoms in these patients. Significantly fewer fosinopril than placebo recipients withdrew or were hospitalised because of worsening heart failure. Additionally, significantly more fosinopril than placebo recipients showed improvement, and fewer patients had deteriorated, in terms of NYHA functional class. Fosinopril and enalapril showed similar clinical efficacy over 6 and 12 months' treatment in patients with NYHA functional class II to IV heart failure. As yet, there are no data showing a mortality benefit with fosinopril. Fosinopril was well tolerated in clinical trials in patients with heart failure. Dizziness (11.9 vs 5.4% for placebo), cough (9.7 vs 5.1%) and hypotension (4.4 vs 0.8%) were the most commonly reported adverse events. In 6- or 12-month comparative studies, fosinopril therapy was associated with a lower incidence of dizziness and hypotension, but a higher incidence of vertigo, than enalapril therapy. 0.8% of patients discontinued the drug because of cough, which occurred to a similar extent with fosinopril and enalapril. Thus, based on available clinical evidence, fosinopril is an effective and well tolerated option for the management of patients with heart failure. Although clinical data are limited, fosinopril may be especially useful in patients with renal or hepatic impairment.

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.

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.
