It was investigated the clinical, lab and plasma digoxin concentration profiles in 15 cardiac heart failure (CHF) outpatients of the Cardiac Heart Service of the Goias Federal University Clinical Hospital. It was aimed to know plasma digoxin concentration profile in 15 cardiac heart failure (CHF) outpatients by two analytical methods, taking account clinical, laboratorial, habits, anthropometric data and drug usage. Digoxin dosage was developed by LC/MS/MS and immunoassay methods; questionnaire and consults handbooks were performed. Results and Conclusions: 87% of the patients who over 46 years of age (33% above 61), the masculine majority; the IC of Chagas disease origin presented greater occurrence, followed of the hipertensive and idiopatic (59%); IC functional classroom II (53.33%); hypertension and diabetes had been distinguished as co-morbidities (26.67% and 20%); tobaccoism, overweight and obesity degree I had presented low occurrence. No patients presented relevant clinical data suggestive of digitalis intoxication. No observed changes in biochemical and hematological exams. The ejection fractions were good by means 41.7 ± 9%. Some drugs with interaction potential had been associated to the treatment, apparently without alterations. Statistical significative difference between both methods was observed (P < 0.05, ANOVA, Tukey Test). In the immunoassay method, all the patients were inside of the therapeutical range (0, 5-2, 0 ng/mL), whereas for the LC-MS/MS method, 8 patients they would be in subtherapeutical concentrations. However, no patient presented signals or symptoms of poisoning or inefficacy of the digoxin, demonstrating biological variability. The two methods are useful, since that it has a correlation with the clinical and laboratorial state of the patients.
