majority of patients (20-22). Based on reported data it
seems that acute myocardial infarction happens mostly
in 60s and early 70s of age.
Our study revealed that among 211 patients, 181 of
them (85.8%) were male and 30 of them (14.2%) were
female which is accordance with the results of other
studies which report that acute myocardial infarction
happens more in men compared to women (16-22).
The results of our study showed that average RPR,
NLR and STR in studied patients were respectively
as 1.01±0.21, 4.07±3.31 and 0.418±0.32. in our study
there was a statistically significant correlation recorded
between mean NLR value based on STR value but
there was no statistically significant correlation recorded
between neutrophil count, lymphocyte count,
RDW, PDW and RPR based on STR value in present
study. It means that average NLR value was significantly
lower in patients with STR>70%. In our study
there was also a significant correlation reported between
neutrophil count, lymphocyte count, NLR, and
RPR based on 2 month complications but there was
no significant relationship found between RDW and
PDW indexes and 2 month complications in studied
patients.
In other studies, NLR index was proved to be an
effective prognostic factor in patients with acute myocardial
infarction.
A study was performed by Yaylak et al in turkey
in 2016 to investigate the relationship between NLR
and right ventricular dysfunction in patients with
acute inferior myocardial infarction. In this study it
was confirmed that NLR was significantly higher in
patients with right ventricular dysfunction followed
by acute inferior myocardial infarction which is in
correspondence with results of our study (16).
In another study performed by Celik et al in turkey
it was reported that RPR was higher in patients with
no reflow areas after primary coronary intervention.
In our study there was no statistically significant correlation
found between RPR and STR, but there was
a significant relationship between RPR and 2 month
complications (17).
In a study performed in Pakistan it was revealed
that cardiac complications and cardiac death were recorded
to be more in patients with higher NLR which
is in correspondence with the results of our study (18).
In a study performed in Japan it was concluded
that RDW and PDW was significantly higher in patients
with acute myocardial infarction (19). In this
study they investigated the difference of these 2 indexes
between patients with angina pectoralis and myocardial
infarction. They proved the diagnostic value
of these 2 indexes but they did nothing to evaluate the
prognostic value of these indexes in their study.
In a study carried out in turkey it was shown that
NLR was significantly higher in patients with grade 3
ischemia. The researchers in this article believe that it
is possible to use NLR as a prognostic and risk assessment
index in patients with acute myocardial infarction
in near future (20), which is in correspondence
with the results of our manuscript.
In another study done in 2013 it was summed up
that NLR was elevated as an independent marker in
patients with no reflow areas after primary coronary
intervention. The researchers of this paper believe
that NLR can be used as a simply accessible and cheap
marker for risk assessment in patients with acute myocardial
infarction (21). Results of this study confirms
the results of Turkmen study of 2013.
To sum up, it is logical to conclude that NLR can
be used for risk assessment and prognosis in patients
with acute myocardial infarction but prognostic value
of other indexes such as RPR, RDW and PDW needs
further evaluation in prospective cohort studies.
There was a study performed in Konakli, Turley
to investigate the relationship between NLR and
coronary reflow in patients undergoing primary angioplasty.
They included a total of 522 patients (417
males and 105 females) with age average of 61.9±11.9
with acute myocardial infarction undergoing primary
coronary angioplasty. The researchers claimed that
in hospital cardiac mortality in patients was higher in
high NLR group (5.77<NLR). The researchers suggest
that NLR>5.77 is an independent marker to predict in
hospital cardiac mortality in patients with acute myocardial
infarction which is in correspondence with the
results of our study (23).
In a study in Hatay, Turkey the researchers aimed
to evaluate the relationship between coronary artery
no reflow and NLR in patients undergoing primary
coronary angioplasty. In this study they included a
number of 204 patients (176 males and 28 females)
with age average of 55.1±9.2 with acute myocardial
infarction. Coronary no reflow was confirmed using
angiography and electrocardiography techniques. The
results of this study showed that patients with coronary
no reflow and no STR (STR<30%) had a higher
NLR level compared to those with partial to complete
