ABSTRACT

Background:

Cardiovascular disease is the leading cause of mortality in the western world and its treatment should be optimized to decrease severe adverse events.

Objective:

To determine the effect of previous use of angiotensin-converting enzyme inhibitors on cardiac troponin I measurement in patients with acute coronary syndrome without ST-segment elevation and evaluate clinical outcomes at 180 days.

Methods:

Prospective, observational study, carried out in a tertiary center, in patients with acute coronary syndrome without ST-segment elevation. Clinical, electrocardiographic and laboratory variables were analyzed, with emphasis on previous use of angiotensin-converting enzyme inhibitors and cardiac troponin I. The Pearson chi-square tests (Pereira) or Fisher's exact test (Armitage) were used, as well as the non-parametric Mann-Whitney's test. Variables with significance levels of <10% were submitted to multiple logistic regression model.

Results:

A total of 457 patients with a mean age of 62.1 years, of whom 63.7% were males, were included. Risk factors such as hypertension (85.3%) and dyslipidemia (75.9%) were the most prevalent, with 35% of diabetics. In the evaluation of events at 180 days, there were 28 deaths (6.2%). The statistical analysis showed that the variables that interfered with troponin elevation (> 0.5 ng / mL) were high blood glucose at admission (p = 0.0034) and ST-segment depression ≥ 0.5 mm in one or more leads (p = 0.0016). The use of angiotensin-converting inhibitors prior to hospitalization was associated with troponin ≤ 0.5 ng / mL (p = 0.0482). The C-statistics for this model was 0.77.

Conclusion:

This study showed a correlation between prior use of angiotensin-converting enzyme inhibitors and reduction in the myocardial necrosis marker troponin I in patients admitted for acute coronary syndrome without ST-segment elevation. However, there are no data available yet to state that this ...
RESUMO
Fundamento A doença cardiovascular é a maior causa de mortalidade no mundo ocidental, devendo seu tratamento ser otimizado, para a redução de eventos adversos graves.

Objetivo:

Determinar o efeito do uso prévio de inibidores da enzima de conversão da angiotensina na mensuração da troponina I cardíaca em pacientes com síndrome coronariana aguda sem supradesnivelamento do segmento ST (SCASST), e avaliar os desfechos clínicos em até 180 dias.

Métodos:

Estudo prospectivo, observacional, em um centro terciário, em pacientes com síndrome coronariana aguda sem supradesnivelamento do segmento ST (SCASST). Foram analisadas variáveis clínicas, eletrocardiográficas e laboratoriais, com ênfase no uso prévio de inibidores da enzima de conversão da angiotensina e dosagem de troponina I cardíaca. Foram usados os testes qui quadrado de Pearson ou exato de Fischer , além do teste não paramétrico de Mann-Whitney. Variáveis com níveis de significância < 10% foram submetidas a modelo de regressão logística múltipla.

Resultados:

Incluídos 457 pacientes, com idade média de 62,1 anos, dos quais 63,7% eram do sexo masculino. Fatores de risco como hipertensão arterial sistêmica (85,3%) e dislipidemia (75,9%) foram os mais prevalentes, com 35% de diabéticos. Na avaliação de eventos em 180 dias, observaram-se 28 óbitos (6,2%). Na análise estatística, as variáveis que interferiram no aumento de troponina (> 0,5 ng/mL) foram a glicemia de admissão elevada (p = 0,0034) e o infradesnivelamento do segmento ST ≥ 0,5 mm, em uma ou mais derivações (p = 0,0016). Relacionada com troponina ≤ 0,5 ng/mL, esteve o uso de inibidores da enzima de conversão da angiotensina prévio à internação (p = 0,0482). ...
