Abstract Abstract 3172 Platelets have a predominant role in the pathogenesis of Acute Coronary Syndromes (ACS). It is believed that the mean platelet size, evaluated by the mean platelet volume (MPV), is a sensitive indicator of platelet reactivity and thrombogenicity potential. Many studies found association between the MPV and the ACS or the occurrence of Acute Myocardial Infarction (AMI). The reasons for this are not well known, but may be due to platelet aggregation or consumption. The aim of this study was to evaluate the MPV in Coronary diseases patients and correlate it with risk factors to these diseases. The patients included were those who would be submitted to procedures like coronariography, angioplasty and myocardial bypass. They were evaluated by a hemogram with the MPV and answered to a questionary about risk factors to coronary disease. We observed that all patients (N=72) had an elevated MPV, ranging from 9.1 to 13,7 and a mean of 11,57fL. The mean age was 63,4 years, being 32% women and 68% men. The mean MPV in the female group was slightly higher than in the men group (11,95 fL vs 11,39), but not statistically significant.(p=0,09) The relation between risk factors and the MPV was as follows: High Corporeal Mass Index had a higher mean MPV (11,63 vs 11,46fl), but no statistically significance was found.(p=0,24) When asked about Hypertension, Diabetes and Dislipidemia, 88,9% confirmed at least one of these diseases, and had a mean MPV higher than those without them. (11,6vs11,3fl) (p<0,0001) When each group, with one of these diseases were compared with the group without them, we observed that the group with diabetes had a higher MPV (11,46 vs 11,30fl)(p=0,01), the same happening with the hypertension group (11,60 vs 11,30fl)(p<0,0001), and in the group of dislipidemic patients, in whom we observed the higher mean value (12,3 vs 11,30 fl)(p=0,019) We could not find differences between the MPV of smokers and no smokers (11,60 vs 11,63 fL)(p=0,9080). The history of previous Myocardial Infarction did not correlate with a higher MPV (11,56 vs 11,61fl)(p=0,41) The family history of coronary diseases did correlate with a higher mean MPV. (11,61vs11,46)(p=0,0201). At last, the use o one anti-aggregating agent was associated with a lower MPV (11,57vs11,59)(p=0,0012). It was expected that all patients had an elevated MPV, and this is observed in some publications. The explanation for these results is linked to the fact that all patients in the study had coronary arterial diseases and probably higher platelet consumption. This consumption stimulates the production of larger platelets, increasing the MPV. The risk factors are highly associated with coronary diseases and that is why they were associated with a higher mean MPV too. The MPV comes with a simple hemogram and is easily done, has no contra-indications, and with a very low cost can be used as a marker of coronary disease. Disclosures: No relevant conflicts of interest to declare.

Abstract Background In most acute coronary artery (ACS) related literature, the female gender constitutes a smaller proportion. This study is based on gender-specific data in the Saudi Acute Myocardial Infarction Registry Program (STARS-1 Program). A prospective multicenter study, conducted with patients diagnosed with ACS in 50 participating hospitals. Results In total, 762 (34.12%) patients were diagnosed with non-ST segment elevation myocardial infarction. Of this group, only 164 (21.52%) were women. The mean age (64.52 ± 12.56 years) was older and the mean body mass index (BMI) was higher (30.58 ± 6.23). A significantly proportion was diabetic or hypertensive; however, a smaller proportion was smoking. Hyperlipidemia was present in 48%. The history of angina/MI/stroke and revascularization was similar, except for renal impairment. The presentation was atypical as only 70% presented with chest pain, and the rest with shortness of breath or epigastric pain. At presentation, the female group were more tachycardiac, had higher blood pressure, and a higher incidence of being in class 11-111 Killip heart failure. Only 32% had a normal systolic function, and the majority had either mild or moderate systolic dysfunction. In particular, the rate of percutaneous coronary intervention was similar. The in-hospital mortality was similar (5%), with more women diagnosed with atrial fibrillation and heart failure at follow-up. Conclusions Women had a higher prevalence of risk factors affecting the presentation and morbidity but not mortality. Improving these risk factors and the lifestyle is a priority to improve the outcome and decrease morbidity.

Background: The Aim of this study was to assess the role of platelet aggregation, mean platelet volume (MPV) and plasma fibrinogen levels in the pathogenesis of acute myocardial infarction (AMI).Methods: A prospective case control study was conducted on 30 cases of AMI and 30 normal healthy age and sex matched controls. The cases and controls were investigated for platelet aggregation studies (done in platelet rich plasma (PRP) using light transmission chrono-log optical aggregometer), MPV (measured by automated cell counter) and plasma fibrinogen levels (estimated by Clauss method).Results: The mean platelet aggregation (%) in cases AMI was 57.61±11.91 which was significantly higher compared with 35.00±10.40 for healthy controls (p<0.001). Using Receiver Operating Characteristic (ROC) analysis, most patients of AMI had a platelet aggregability of ≥49% on optical aggregometry (sensitivity = 83.3 % and specificity = 93.7%). The MPV (fL) in cases of AMI was 8.04±0.39 which was significantly larger when compared with 7.67±0.43 for controls (p= 0.001). The mean plasma fibrinogen concentration in cases of AMI was 383.1±48.3mg/dl which was significantly higher when compared with 271.33±57.7mg/dl for healthy controls (p<0.001).Conclusions: Platelet hyperaggregability, elevated MPV and plasma fibrinogen levels are found in patients with AMI and contribute significantly to risk of developing coronary thrombosis. These variables should be considered as additional screening tools to identify individuals at increased risk of developing AMI.

Background: Among acute coronary patients, the ratio of non ST-elevation myocardial infarction (NSTEMI) is increasing and according to recent studies, less than 30% of myocardial infarctions (MIs) are due to ST-elevation myocardial infarction (STEMI). Unlike STEMI, in NSTEMI the ECG is not able to identify the culprit vessel. Objectives: In this study, we aimed to evaluate the association of mean platelet volume (MPV) and NSTEMI due to left anterior descending lesion. Methods: In this cross sectional study 349 patients with NSTEMI were included. Major cardiac risk factors (cigarette, diabetes mellitus (DM), hypertension (HTN), hyperlipidemia (HLP), angiographic findings, and drug history of patients were extracted from patients’ medical files. Then the MPV in complete blood count results and angiography findings were analyzed for any association. According to culprit lesions patients were divided into left anterior descending (LAD) and non-LAD groups. Results: There was a significant difference between the two groups (LAD vs. non-LAD) according to platelet count (P = 0.014), MPV (P = 0.001), HLP (0.024) and DM (0.048). Multivariate regression model has shown the MPV (OR = 0.46, 95%CI = 0.27 - 0.78) and DM (OR = 0.18, 95%CI = 0.06 - 0.54) as independent risk factors for NSTEMI due to LAD lesion. The significant positive correlation was also seen between MPV and left ventricle ejection fraction (LVEF) (r = 0.22, P = 0.006). The area under the curve (AUC) of MPV for predicting LAD culprit lesion was calculated as 69% (P < 0.0001). At cut off point of 9.15, has sensitivity and specificity of MPV for predicting LAD as culprit vessel was 100% and 30% respectively. Conclusions: In NSTEMI patients MPV might be a good tool to differentiate patients with LAD as culprit vessel.

SummaryPatients undergoing surgery for coronary artery bypass graft or heart valve replacement had their platelet count and mean volume measured pre-operatively, immediately post-operatively and serially for up to 48 days after the surgical procedure. The mean pre-operative platelet count of 1.95 ± 0.11 × 1011/1 (n = 26) fell significantly to 1.35 ± 0.09 × 1011/1 immediately post-operatively (p <0.001) (n = 22), without a significant alteration in the mean platelet volume. The average platelet count rose to a maximum of 5.07 ± 0.66 × 1011/1 between days 14 and 17 after surgery while the average mean platelet volume fell from preparative and post-operative values of 7.25 ± 0.14 and 7.20 ± 0.14 fl respectively to a minimum of 6.16 ± 0.16 fl by day 20. Seven patients were followed for 32 days or longer after the operation. By this time they had achieved steady state thrombopoiesis and their average platelet count was 2.44 ± 0.33 × 1011/1, significantly higher than the pre-operative value (p <0.05), while their average mean platelet volume was 6.63 ± 0.21 fl, significantly lower than before surgery (p <0.001). The pre-operative values for the platelet volume and counts of these patients were significantly different from a control group of 32 young males, while the chronic post-operative values were not. These long term changes in platelet volume and count may reflect changes in the thrombopoietic control system secondary to the corrective surgery.
