Aim. To assess pharmacological evidence-based-treatment before admission in patients with heart failure (HF) due to systolic dysfunction, New York Heart Association functional class (FC) III/IV who are hospitalized at Coronary Unit. Material and methods. Prospective study of patients hospitalized consecutively at Coronary Unit within June 2007 - June 2009. Patients with HF and dilated cardiomyopathy FC III/IV and echocardiographic ventricular function impairment where included. Two groups where formed: patients with HF diagnosis within admission (admission group -AG-), in which we compared medication at discharge vs treatment at discharge of treatment group (TG); and patients with HF diagnosis for more than 1 year (3.3 years/SD 2.1), TG, in which we compared medication at admission vs medication at discharge. Proportions test, Statistix program, adjusted by Fisher’s test was used for statistical analysis. Results. Average age was 55.2±11.2 years in AG and 60.3±11.3 years in TG (p=NS). There was masculine dominance (65% AG and 79.7% TG). 90% of patients in AG and 83.3% of patients in TG (p=NS) presented cardiomegaly at chest X-ray and moderate to severe impairment of ventricular function; with a mortality of 4 patients in AG (18.1%) and 24 in TG (28.5%) (p=NS). In TG there was relatively low indication of evidence-based-treatment at admission (60.7% furosemide; 32.1% spirinolactone; 58.35% angiotensin converting enzyme inhibitors (ACEi); 25% beta blockers and 27.3% digitalis), showing better results in comparison with discharge treatment. Regarding therapeutic resorts optimization, AG treatment at discharge was similar than TG’s. Conclusion. Comparisons within AG and TG treatment at discharge only showed statistically significant differences about beta blocker indication. Based on evidence, HF outpatients pharmacological treatment is less optimal, and tolerability to a mayor use of drugs with high impact in morbidity and mortality does not constitute a limitation to its use.
