Background: Angiotensin-converting enzyme inhibitors and angiotensin receptor blockers improve prognosis in congestive heart failure and are the treatment of choice in these patients; despite this, the rates of ACE-I[1] usage in heart failure patients remain low in clinical practice.

Objectives: To evaluate the rate of ACE-I/ARB[2] treatment in hospitalized patients with CHF[3], and analyze the reasons for non-treatment.

Methods: We prospectively evaluated 362 consecutive patients hospitalized with CHF. Patients were evaluated for ACE-I/ARB usage at discharge and were followed for 1 year.

Results: At hospital discharge 70% of the patients were prescribed ACE-I/ARB treatment. Only 69% received recommended target or sub-target dosages, proven to improve prognosis. This decreased to 63% and 59% at 6 months and 12 months of follow-up respectively, due to a shift from sub-target levels to low dosages. Justified reasons for under-treatment were apparent in only 25% not optimally treated discharged patients and this decreased to 12% and 4% at 6 and 12 months follow-up, respectively. Common reasons for non-treatment at discharge were hyperkalemia and elevation in serum creatinine, while hypotension and cough were more prominent at follow-up. Clinical parameters associated with increased treatment rates were ischemic heart disease and the absence of chronic renal failure. Patients receiving treatment had lower hospitalization and mortality rates.

Conclusions: ACE-I/ARB treatment is still underutilized in patients discharged from hospital with a diagnosis of CHF. Increasing the awareness of the importance of these drugs may increase the number of patients treated.

 Renin-angiotensin-aldosterone systems play a critical role in the development and progression of cardiovascular diseases, and inhibitors of angiotensin-converting enzyme have proven effective for the treatment of these diseases. Since angiotensin II receptor antagonists can inhibit the effects of angiotensin II via ACE-independent pathways, e.g., chymase, they were considered to be more effective than ACEIs. On the other hand, ACE inhibitors can increase bradykinin, and thus, nitric oxide, which may cause potent cardioprotection, inhibition of smooth muscle proliferation and attenuation of inflammation mechanisms. It appears that angiotensin II receptor antagonists and ACEIs may mediate cardioprotection in different ways. This is the rationale to explore the possibility of a combined administration of both drugs for the treatment of chronic heart failure and other cardiovascular pathology. In this review we try to analyze the role of ACE, kinins and chymase inhibition in the pathophysiology and treatment of cardiovascular diseases.
