[Clinical and demographic characteristics of an outpatient Russian population with chronic heart failure at the time of enrollment in the QUALIFY registry for evaluating consistency with clinical guidelines on drug therapy].

BACKGROUND

Chronic heart failure is the most common condition in patients with cardiovascular diseases. Therefore, evaluating consistency of doctor's recommendations with guidelines on drug therapy is a relevant issue.

AIM: To evaluate consistency of doctor's recommendations with guidelines on drug therapy for CHF.

MATERIALS AND

METHODS

The study presents enrollment visit data for the Russian part of the international prospective registry, QUALIFY. The study included 404 outpatient patients with CHF between February, 2013 through June, 2014. Consistency with guidelines for drug therapy was evaluated for 5 drug classes, including ACE inhibitors (ACEI), β-blockers (BB), angiotensin receptor antagonists (ARA), mineralocorticoid receptor antagonists (MRA), and ivabradine.

RESULTS

On the whole, the consistency was good in 64.9% of cases, moderate in 27.7% of cases, and poor in 7.4% of cases. Proportions of patients who received a target dose of a medicine and a dose ≥50% of the target dose were low, 21.5% and 62.3% for ACEI; 15% and 50.8% for BB; 20.3% and 39.8% for ARA; and 23.4% and 78.7% for ivabradine, respectively. These values, except for BB, were lower for patients with late hospitalization (hospitalization ≥6 months vs.
