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.

1. Mean platelet volume and count were measured in three groups: patients with acute myocardial infarction, a control group with myocardial ischaemia but no infarction and an asymptomatic group of young males. 2. Mean platelet volume was significantly larger in the myocardial infarction group compared with the ischaemic heart disease group or the asymptomatic group. 3. Two subpopulations were present within the myocardial infarction group. One subgroup had a large mean platelet volume and low count. The other subpopulation was indistinguishable, with regard to platelet count and mean volume, from the ischaemic heart disease group. 4. Over 60% of the myocardial infarction group lay in the area of high platelet volume and low count compared with 13% of the ischaemic heart disease control group and 38% of the asymptomatic group. Acute myocardial infarction is likely to be associated with a large mean platelet volume and low count compared with the ischaemic heart disease group. There is no statistical evidence that this condition is related to smoking or size and site of infarct. 5. This evidence suggests that large mean platelet volume and low platelet count could be a major risk factor for myocardial infarction.

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.
