[Pharmacotherapeutic profile of patients with acute myocardial infarct in the early hospitalization period].
BACKGROUND
The early treatment efficacy of patients with acute myocardial infarction (AMI) with thrombolysis, antiplatelet drugs, betablockers and ACE inhibitors has been well documented in randomized mega trials. However, little is known about the fact to what extend the results of these mega trials have influenced the treatment practices. Moreover, in the view of a complete lack of data on management of patients with AMI in Slovak Republic a project of the Ministry of Health "Audit of diagnostic and therapeutic management in patients with acute coronary syndromes" (AUDIT) has been conducted.


OBJECTIVE
To obtain preliminary information on the present state of pharmacotherapy of patients with AMI in Slovak Republic during the early hospitalization phase (EHP) from the Pilot Study (PS) of the project AUDIT.


METHODS
Pharmacotherapy of AMI during EHP was analysed in 336 patients (232 males and 104 females, mean age 65 12 years, age range 30-93 years). Patients admitted with diagnosis of the first or repeated AMI or with suspect AMI were included. PS was done in prospective multicentric study between November 1, 1996 and December 31, 1996. 23 hospitals from various parts of Slovakia participated in this study. Data were compiled by means of questionaires and were processed by ACCES 97 and EXCEL 97.


RESULTS
Antiplatelet therapy with acetylosalicylic acid (almost exclusively Anopyrin) received as much as 87.8% of patients with AMI during EHP. Thrombolytic therapy (TLT), almost exclusively with streptokinase, was performed in 105, i.e. in 31.8% of patients with AMI. TLT was performed in a statistically significantly smaller proportion of patients older than 65 years compared to patients 65 years of age and younger (20.9% vs 41.2%, p < or = 0.01). Females were treated with TLT statistically significantly less frequently than males (24.5% vs 35.1%, p < or = 0.05). The major cause for not performing the TLT was late arrival to hospital (in 32.1% patients). Betablockers were administered to a total of 42.9% of patients during EHP. Betablockers received only 3.6% of patients intravenously (!) and only 39.3% of patients orally. Treatment with oral betablockers was performed in a statistically significantly smaller proportion of patients older than 65 years compared to patients 65 years of age and younger (27.4% vs 49.7%, p < or = 0.01). Up to 49.1% of patients in EHP were treated with ACE inhibitors, however, left ventricular ejection fraction < 40% warranting feasibility of this treatment was achieved only in 26.7% of patients. Nitrates were administered to 62% of patients in EHP, of this number intravenously to 37.4% of patients. Calcium channel blockers were given only to 7.3% of patients. Treatment with heparin was performed in 90.9% of patients. 14.3% of patients received during EHP antiarrhythmics of class I and 2.7% of patients of class III. MgSO4 was used in 26.4% of patients in EHP.


CONCLUSIONS
The reported PS of AUDIT Project gives for the first time information on the state of the pharmacotherapy of patients with AMI in Slovak Republic. Some results are relatively encouraging, however, others can not be a reason for satisfaction. The fact, that in Slovakia, adequate number of patients with AMI receive acetylosalicylic acid (Anopyrin) and that Slovakia belongs to countries with the smallest proportion of patients with AMI treated with calcium channel blockers and antiarrhythmics during EHP is encouraging. On the other hand, the use of TLT and betablockers is dissatisfactory. Requirement to increase the proportion of thrombolysed patients with AMI and the necessity for substantially more frequent use of betablockers, especially intravenous, in EHP in these patients result from these findings. In Slovakia, inadequately large proportion of patients with AMI is treated with ACE inhibitors, heparin, and partially also nitrates administered per os during EHP. (ABSTRACT TRUNCATED)
