Introduction:
Among the risk factors of stroke meteorological
conditions are present. They are forecastable and have practical
importance in the acute care. Previously we demonstrated
a meteorological parameter, the equivalent potential
temperature (EPT), anomalous value of which (aEPT) indicates
an unfavourable effect on acute ischemic stroke (AIS) outcome.
As compare ischemic stroke and myocardial infarction, we
found different behaviour of these two disorders. The EPT
characterizes air masses from different regions, a significant
deviation from the 30-year average is the anomalous period
or day (AD). In present work aEPT was compared to the onset
of AIS. The indicator for AIS was the number of thrombolysis
(TT). The narrow time window of TT enables the precise
determination of the disease onset. Patients and method: We
compared the number of TTs and aEPT periods in Budapest
region during 01.12.2014-28.02.2015 (the period was chosen
to have possibility of comparison with previous data). Because
of the atmospheric conditions of the Carpathian Basin we
analyzed the winter months. Patients’ data were analyzed
anonymously. The daily numbers of TTs were provided by the
National Institute of Health Insurance Fund Management.
Statistics were done by Student’s t-test.
Results:
Of the90days 32wereADs. Thenumber of TTswas 243,
69 (28.4%) of it were performed on ADs. The average number
of TTs was 2.16 on ADs and 3.00 on non-ADs. TT rate was 1.86
during positive, 2.8 during negative aEPTs periods. There was
no statistically significant difference (p=0,3684) between ADs
and non-ADs.
Conclusion:
we did not find an increase (but rather a decrease)
in AIS during aEPT periods. This apparently contradicts the
relationship between the aEPT value and the fatal outcome of
stroke. The reason may be that patients treated with TT are not
among the most serious cases, which increase the mortality
rate.

Andras Folyovich graduated at the Medical Faculty of Semmelweis University, and
trained at the Department of Neurology of the same university. He obtained Board
Certification in Neurology in 1983, in Psychiatry in 1993 and in Vascular Neurology in
2015. His PhD dissertation dealt with socio-economical aspects of stroke. He has been
a pioneer in widening medical enteral nutrition of acute stroke patients in Hungary.
