RT Journal Article SR Electronic T1 Seasonal variation in enzymatic infract size and mortality in patients with ST-segment elevation myocardial infarction JF Saudi Medical Journal JO Saudi Med J FD Prince Sultan Military Medical City SP 353 OP 357 VO 30 IS 3 A1 Sohrabi, Bahram A1 Kazemi, Babak A1 Aghazadeh, Behzad YR 2009 UL http://smj.org.sa/content/30/3/353.abstract AB OBJECTIVE: To investigate any seasonal variation in enzymatic size, mortality rate, and localization of ST-segment elevation myocardial infraction (STEMI).METHODS: Between March 2003 and September 2006, all patients admitted to the Madani Heart Center, Tabriz, Iran with the diagnosis of acute myocardial infarction (AMI) were included in this observational prospective study. Cases were divided into 4 groups according to the season that MI occurred, and enzymatic size and location were determined for each patient.RESULTS: One thousand and two hundred six cases of AMI were analyzed during the study period. In our study, no seasonal difference was observed in demographic characteristics of patients. Also, no significant seasonal variation was found in enzymatic infract size, MI location, and in-hospital mortality rate.CONCLUSION: Our findings does not support the hypothesis that enzymatic size, mortality rates, and location of STEMI varies by seasons.
