ABSTRACT
OBJECTIVES:
This study evaluated the impact of clinical and physiological factors limiting treatment optimization toward recommended medical therapy in heart failure (HF).BACKGROUND:
Although guidelines aim to assist physicians in prescribing evidence-based therapies and to improve outcomes of patients with HF and reduced ejection fraction (HFrEF), gaps in clinical care persist.METHODS:
Medical records of all patients with HFrEF followed for at least 6 months at the authors' HF clinic (n = 511) allowed for drug optimization and were reviewed regarding the prescription rates of recommended pharmacological agents and devices (implantable cardioverter-defibrillator [ICD] or cardiac resynchronization therapy [CRT]). Then, an algorithm integrating clinical (New York Heart Association [NYHA] functional class, heart rate, blood pressure and biologic parameters (creatinine, serum potassium) based on the inclusion/exclusion criteria of landmark trials guiding these recommendations) was applied for each agent and device to identify potential explanations for treatment gaps.RESULTS:
Gross prescription rates were high for beta-blockers (98.6%), mineralocorticoid receptor antagonist (MRA) (93.4%), vasodilators (90.3%), ICDs (75.1%), and CRT (82.1%) among those eligible, except for ivabradine (46.3%, n = 41). However, achievement of target physiological doses was lower (beta-blockers, 67.5%; MRA, 58.9%; and vasodilators, 63.4%), and one-fifth of patient dosages were still being up-titrated. Suboptimal doses were associated with older age (odds ratio [OR] 1.221; p < 0.0001) and history of stroke or transient ischemic attack (TIA) (no vs. yes, OR 0.264; p = 0.0336).CONCLUSIONS:
Gaps in adherence to guidelines exist in specialized HF setting and are mostly explained by limiting physiological factors rather than inertia. Older age and history of stroke/TIA, potential markers of frailty, are associated with suboptimal doses of guideline-directed medical therapy, suggesting that an individualized rather than a "one-size-fits-all" approach may be required.Palavras-chave
