[Effectiveness of Lisinopril in the treatment of heart failure].

A prospective study was performed in patients (30 M, 16 F, mean age of 56.0 +/- 9.2 [42-73] years) with congestive heart failure to assess the efficacy of lisinopril during a 16 weeks treatment period. Changes in clinical signs, functional capacity, blood pressure, heart rate, echocardiographic parameters, exercise duration, laboratory data and quality of life were measured. After a 2-week run-in period starting daily dose of study drug was 5 mg, and an increase of medication was considered at 4 weeks. At the end of the study mean daily dose of lisinopril was 15.1 +/- 6.2 mg. Improvement of NYHA status by 2 grades was observed in 4 cases (9%), by 1 grade in 24 cases (51%), there was no change in 17 cases (38%), and worsening was observed in 1 case (2%). During the study both systolic (p = 0.001) and diastolic blood pressure (p = 0.0006) decreased significantly, the changes in pulse rate were not significant. Left ventricular end systolic (p = 0.001) and end diastolic (p = 0.003) dimensions decreased, ejection fraction rose by 4.4% (p = 0.0002). One patient was removed from the study because of drug-induced cough. Comparison of all the laboratory data for pre and post-study periods did not reveal any significant difference. Patients treated with lisinopril improved significantly for clinical, haemodynamic, echocardiographic and quality of life parameters, with few adverse experiences, good tolerability and once-daily dose.

[The rate of acetylsalicylic acid non-respondents among patients hospitalized for acute coronary disease, previously undergoing secondary salicylic acid prophylaxis].

The authors determined the rate of acetylsalicylic acid (ASA) non-responders among patients receiving secondary prevention due to cardiovascular diseases at the appearance of acute coronary events. The non-responders were defined as: patients who have been treated with ASA because of acute coronary syndrome, but the subsequently performed platelet aggregation study did not confirmed an appropriate platelet inhibition. Among the 75 patients being investigated (44 male, 31 female, average age: 61.3 ys) 21 were hospitalized due to acute myocardial infarction and 54 for unstable angina, respectively. The daily doses of ASA were 200-325 mg. The aggregation of platelets was measured within 24 h after the admission. The investigations were performed with different amounts of 4 different inducers (ADP, arachidonic acid, epinephrine and collagen) taking dose-response curves. The antiaggregatory treatment with ASA was considered to be ineffective if the typical aggregation curves were obtained above the following final concentrations of the inducers: ADP: > 5 microM, epinephrine: > 5 microM, arachidonic acid: > 250 microM, collagen: > 2 micrograms/ml. These upper-threshold concentrations of the inducers were determined with the help of the data of healthy drug free volunteers. Twenty-six of the 75 patients (34%) were found to be non-responder to ASA, whereas the antiaggregatory effect of ASA was proven in 49 cases. No differences were found in gender. The compliance was proven with the HPLC-determination of urinary metabolites of ASA performed immediately after the upon admission. Seven patients (10.9%) showed a non-compliance, not showing any traces of ASA-metabolites in their urine. The authors emphasizing the importance of the laboratory control even of the prophylactic ASA treatment in order to continue the effective antiaggregatory therapy with other effective drugs.
