Summary:

Purpose of the study: to evaluate the prognostic value of brain natriuretic peptide (BNP) as a predictor of cardiovascular events in patients with acute coronary syndrome (ACS) within one year after hospitalization. Material and Methods. The study included 201 patients, including 150 men and 51 women, who were treated in the emergency department of cardiology with ACS including 96 patients without symptoms of CHF and/or AHF. Results. All patients were divided into groups depending on the presence signs of heart failure of CHF and/or AHF at the time of admission: patients with no signs of heart failure were divided into 2 groups: those with BNP levels >101 pg/mL (group 1; n=37) and <100 pg/mL (group 2; n=59); the third group consisted of patients with symptomatic HF (n=105). In patients without clinical signs of CHF and/or AHF with elevated level of the BNP at the time of hospitalization was observed significantly increased risk of unstable angina during the year compared to patients with normal levels (OR 2.83 [95% Cl: 1.1—7.24], p=0.04). In patients without clinical signs of CHF and/or AHF with elevated BNP levels at the time of hospitalization compared to patients with AHF and/or CHF, had no statistically significant differences in the long-term prognosis. Conclusion. Patients with ACS in the absence of CHF and/or AHF but with elevated levels of BNP at admission should be attributed to the group of high risk for cardiovascular complications. Increasing the level of BNP in ACS patients at admission has an adverse value for long-term outcome and can be used as an additional risk marker.

Leukocytosis and clinical outcomes in patients with myocardial infarction with ST-segment elevation

Year: 2013, volume 9 Issue: №4 Pages: 673-678
Heading: Сardiology Article type: Original article

Summary:

The aim of the study is to evaluate the frequency of occurrence of leukocytosis and its prognostic value for the course and outcome of myocardial infarction with ST-segment elevation. Material and Methods. The study included 245 patients aged 61,2 years, who were on treatment at the Department of Emergency Cardiology with diagnosis of acute myocardial infarction with ST-segment elevation. Results. Leukocytosis (white blood cell levels of more than 10*109/L) was observed in 34,7% of patients. The presence of leukocytosis was associated with increased incidence of congestive heart failure class IV at Killip, ventricular fibrillation and lethal outcomes during hospitalization. There were no significant differences in the incidence of adverse events in the long-term period between the patients with leukocytosis and with normal level of white blood cells. Conclusion. Increased levels of white blood cells (more than 10*109/L) in patients with myocardial infarction with ST-segment elevation is associated with a significantly increase relative risk of cardiogenic shock (Odds ratio 5,2, 95% Cl, 1,7-15,8, p=0.001), ventricular fibrillation (Odds ratio 8,5, 95% Cl, 1,9-38,3, p=0.001) and death during hospitalization (Odds ratio 2,47, 95% Cl, 1,87-38,4, p=0,03). The level of white blood cells on admission to hospital may be used as one of the additional factors predicting the risk of patients with myocardial infarction with ST-segment elevation during hospitalization.
