Introduction. In the west world the heart failure is the illness that has the most incidence, admissions and costs to the health systems. Objectives. To make a database, look for any tendency in retrospective observation. To analyze the issue in our area, to learn about the follow-up and transform the heart failure office in a more complex unit with phone follow-up. Material and method. Since 02-24-94 until the date, were included 118 patients, storing of each of them in data base: age, sex, risk factors, etiology, clinical and echocardiographic evolution, drugs used in medical treatment, alternatives treatments, transplantations, peak O₂ consumption, start of beta bloquers treatment, functional class before and after it, mortality, causes of death, coronary artery by pass graft, cardiac transplantations, pacemakers, percutaneous transluminal coronary angioplasty, admitions before and after beta blockers, Na, K, date of first and last consult, follow up in months. Diabetes, high hypertension arterial, electrokardiogrham and left ventricular hypertrophy. Results. The age media was 60.9 ± 11.09, 82% were male and 18% female. The ischemic etiology was 28%, hypertensive 24%, idiopathic 22%, chagasic 17% and 9% was valvular disease. From 118 patients are in follow-up at date 33 (27%), 5 of them are waiting cardiac transplantation, 7 (21%) were transplanted. The media from the first symptom to last consultation was 7.46 years. The most frequent initial symptom was dyspnea 51.51%. The media functional class at the beginning of the follow-up was 2.63±0.83 and at the end was 2.15±0.97. Nineteen deaths (57%) happened during the follow up. The causes of death were: sudden death 8 (42%), terminal heart failure 4 (21%), others cardiovascular causes 5 (26%), non cardiac death 2 (10.52%). The follow-up media was 45.53 months, were lost in the follow up 52% of the patients. All patients have clinic and echocardiographic follow-up, 27% of total were studied with peak O₂ consumption. The 100% were treated with beta blockers, 75% with enalapril, 0.9% inhibitors AT1 and 60% with spironolactone. Acenocumarol, digoxin, AAS, furosemida, hidroclorotiazida, amiodarone y mexitilene too. Conclusions. The heart failure has high incidence and prevalence in our area, the most frequent etiology was the ischemic. The media of follow-up is high with a high lost in it, that we believe is attributable to a non follow-up phone. The mortality is high; the most frequent cause was sudden death. The use of beta blockers, enzyme converter Angiotensin inhibitor and spironolactone was elevated.
