Objective. The aim of the present study was to compare differencesof symptoms, comorbidities, risk factors and outcomes inyounger (up to 55 years-old) and older (over 55 years-old) womenwith acute myocardial infarction.Materials and methods. In this retrospective study we analised473 cases of women with acute myocardial infarction treated in2012. Patients were divided into two groups according to theirage: group I (up to 55 years) and group II (older than 55 years).The first group included 37 patients while the second group – 436patients.Results. The average age of patients was 72,3 ± 11,07 m. Myocardialinfarction with ST elevation were diagnosed to 54,3%, ofwich Q+ 70,4%, Q- 29,6% (p < 0,001), non-ST elevation 45,7%,of wich Q+ 6,5%, Q- 93,5% (p < 0,001), no statistically significantdifference was observed between the groups. 73% women ingroup I had primary arterial hypertension (I grade 2,7%, II 59,5%,III 10,8%), in the second group – 92,7% (I grade 0,7%, II 86%,III 6%), (p < 0,001). Moreover, 13,5% patients in group I haddiabetes (5,4% of type I, 8,1% of type II), in the group II 23,9%(0,3% of type I, 23,6% of type II), (p < 0,001). Heart rhythm disorderswere more often in women over 55 years-old (32,8%),(p=0,006). Among these patients, persistent atrial fibrilation wereidentified in 27,2%, permanent atrial fibrilation in 18,4%, ventricularfibrilation in 4,1% patients (all p < 0,001). 5,4% women inyounger group had previously experienced myocardial infarctionwhile in older group – 20% (p=0,03). The spread of the pain to lefthand was more common in the group of younger patients (27%)(p=0,047). Futhermore, in group I 18,9% felt weakness, whilein group II – 38,5% (p=0,018). Fatal outcomes were observed in6,8% patients, all of them were older than 55 years. Among patientswith fatal outcomes Killip IV were found to 78,1% patients(p < 0,001).Conclusions. Older women (≥ 55 years-old) treated for acutemyocardial infarction more often had the grade II of primary arterialhypertension, heart rhythm disorder, previously experiencedmycardial infarction and felt weakness. Younger patients (below55 years old) had type I diabetes more often and were characterizedby pain spreading to the left arm. Determined Killip IV leadedto increased lethality.
