The aim of this study was to assess the trends of myocardial infarction (MI) morbidity and evaluate the associations with some meteorological factors.
Data on MI morbidity were collected from Kaunas ischemic heart disease registry and information about meteorological factors from Kaunas meteorological station was collected.
The overall morbidity rates of acute MI among men aged 25-64 increased by 2.0%/yr. (P=0.02), whereas among women did not change significantly (+1.2%/yr., P=0.2) during 1995-2007. Among men aged 65-84 the overall morbidity rates of MI were without significant changes (-1.0%/yr., P=0.3) and among women decreased significantly by -1.7%/yr. (P=0.03). During 1995-2000, a weak inverse significant correlation between atmospheric air temperature and morbidity of MI (r=-0.05, P=0.019) was documented (in women and the elderly r=-0.045 and -0.048, respectively, P<0.05). Weak correlation between atmospheric air wind speed and MI morbidity in women (r=-0.042, P=0.05) and in population of older age (r=-0.056, P=0.099) was determined. In men and in elderly population a direct weak correlation between atmospheric pressure and MI morbidity was found (r=0.114 and 0.166, respectively, P<0.01). In this study monthly and seasonal variation of MI rates were observed. In winter period MI rates were higher to compare with other seasons (χ(2)=18.682, df=3, P<0.0001).
The overall morbidity rates of MI increased among Kaunas men aged 25-64 and tended to increase among women, whereas among men aged 65-84 MI morbidity trends were without statistically significant changes and significantly decreased among women during 1995-2007. Weak inverse correlations between atmospheric air temperatures, rainfall level and direct correlation between air wind speed, atmospheric pressure and MI morbidity were established. Months/seasonal variations during analyzed period were observed.
本研究旨在评估心肌梗死（MI）发病率的趋势，并评估其与一些气象因素的关联。
从考纳斯缺血性心脏病登记处收集MI发病率数据，并从考纳斯气象站收集气象因素信息。
1995 - 2007年期间，25 - 64岁男性急性MI的总体发病率每年增加2.0%（P = 0.02），而女性则无显著变化（每年增加1.2%，P = 0.2）。65 - 84岁男性MI的总体发病率无显著变化（每年下降1.0%，P = 0.3），而女性则显著下降，每年下降1.7%（P = 0.03）。1995 - 2000年期间，记录到大气气温与MI发病率之间存在弱的负相关（r = -0.05，P = 0.019）（女性和老年人中r分别为-0.045和-0.048，P < 0.05）。确定了大气风速与女性MI发病率（r = -0.042，P = 0.05）以及老年人群MI发病率（r = -0.056，P = 0.099）之间的弱相关性。在男性和老年人群中，发现大气压力与MI发病率之间存在直接的弱相关性（r分别为0.114和0.166，P < 0.01）。在本研究中观察到MI发病率的月度和季节性变化。与其他季节相比，冬季MI发病率更高（χ(2)=18.682，自由度=3，P < 0.0001）。
1995 - 2007年期间，考纳斯25 - 64岁男性MI的总体发病率增加，女性有增加趋势，而65 - 84岁男性MI发病率趋势无统计学显著变化，女性则显著下降。建立了大气气温、降雨量水平与MI发病率之间的弱负相关以及风速、大气压力与MI发病率之间的直接相关性。观察到分析期间的月份/季节变化。
