Individual parameters of complete blood count (CBC) have been associated with worse outcome in patients with acute coronary syndrome (ACS). However, the prognostic role of CBC taken as a whole has never been evaluated for long-term incidence of major adverse cardiovascular events (MACEs). Patients were grouped according to their hematopoietic cells’ inflammatory response at different time points during hospital stay. Patients with admission white blood cell count >10 × 109/L, discharge hemoglobin <120 g/L, and discharge platelet count >250 × 109/L were defined as “high-risk CBC.” Among 1076 patients with ACS discharged alive, 129 (12%) had a “high-risk CBC” and 947 (88%) had a “low-risk CBC.” Patients with “high-risk CBC” were older and had more comorbidities. Over a median follow-up of 665 days, they experienced a higher incidence of MACE compared to “low-risk CBC” patients (18.6% vs 8.1%). After adjustment for age, age-adjusted Charlson comorbidity index, female sex, cardiac arrest, suboptimal discharge therapy, coronary artery bypass, and ejection fraction, a high-risk CBC was significantly associated with increased MACE occurrence (adjusted hazard ratio 1.80; 95% CI: 1.09-3.00). The CBC was a prognostic marker in patients with ACS, and its evaluation at admission and discharge could better classify patient’s risk and improve therapeutic management.

Long Term Prognosis

BACKGROUND: It has been shown that Myeloperoxidase (MPO) is intimately involved in pathogenesis of atherosclerosis and Acute Coronary Syndrome (ACS). Small studies have shown that high levels of MPO are a poor prognostic factor in patients presenting with ACS. However, due to the small nature of these studies, the relationship between MPO and outcomes has not been confirmed. Here we aimed to examine the prognostic value of MPO in patients with ACS. METHODS: We performed a meta-analysis to compare the long-term prognosis of ACS patients with high MPO and low MPO levels. The literature was retrieved by formal searches of electronic databases (PubMed, EMBASE, Medline, OVID, and web of knowledge) from inception to November 2013. A total of 16 trials were included in this meta-analysis involving 10572 patients. Data were analyzed using random-effects model and study quality was assessed using appropriate scales. RESULTS: High MPO group was associated with overall worse outcomes than low MPO group in terms of recurrent myocardial infarction (9% [211 of 2336] vs. 7.7% [240 of 3101], odds ratio [OR] 1.4, 95% confidence interval [CI]: 0.92-2.15, p 0.11); all cause mortality (8% [236 of 2920] vs. 5% [209 of 4263], OR 1.83, 95% CI: 1.31-2.54, p <0.0004) and Major Adverse Cardiovascular Events (MACE) (24% [334 of 1400] vs. 14% [133 of 949], OR 2.04, 95% CI: 1.46-2.85, p< 0.0001) (Figure). CONCLUSIONS: In this meta-analysis examining the long-term outcomes in ACS patients, high MPO levels were associated with worse outcomes. These observations support prospective trials tailoring more aggressive therapy to patients with suspected worse prognosis.

Prognostic Utility

Background: Acute coronary syndrome (ACS) is the leading cause for morbidity and mortality in developed countries. Numerous groups have explored single and multiple biomarker strategies to identify diagnostic prognosticators of ACS which will improve our ability to identify high-risk individuals. Matrix metalloproteinase (MMP-9) is one potential biomarker which has been widely studied in ACS. Recent reports have showed the prognostic utility of MMP-9, but due to inconsistent results, it has not been possible to draw firm conclusions. Objective: This review aims to explore the ability of MMP-9 to predict long-term prognosis of ACS. To clarify this issue, we conducted a literature review to provide a comprehensive assessment of MMP-9 levels in ACS patients. Method: We retrieved a total of 1501 articles from PubMed and Google Scholar. After thorough scrutiny, 12 original research articles were found fulfilling the inclusion exclusion criteria. MMP-9’s ability as a biomarker of prognostication post ACS was reviewed. PRISMA guidelines were used for reporting. Result: The results revealed that MMP-9, apart from being an efficient diagnostic biomarker for ACS, helps in predicting the future risk of ACS with disease outcome. Positive correlation was found between plasma MMP-9 and left ventricular remodeling. A positive association was also found between cardiovascular death and higher MMP-9 levels. Conclusion: MMP-9 can be a potential prognostic marker for ACS and aid in identifying high risk patients for intensive management during follow -up.
