Инфаркт миокарда на сегодняшний день – актуальная проблема в медицине, которая является главной причиной смертности в мире. Тяжесть течения и исход заболевания зачастую зависит от сопутствующих патологий, имеющихся у пациента на момент развития инфаркта миокарда. К одному из наиболее значимых большинство исследователей относит внебольничную пневмонию. Последняя по-прежнему остается одной из ведущих патологий в группе болезней органов дыхания. В то же время не стоит забывать, что вторая форма клинического течения пневмонии, нозокомиальная пневмония, также достоверно оказывает значительное влияние на течение и исход инфаркта миокарда.

   Myocardial infarction is a current problem in medicine, being the leading cause of death in the world. Severity and the outcome of the disease depends on concomitant pathologies which the patient has at the time of myocardial infarction. In our study, we give a comparative description of the groups of patients with two forms of the clinical pneumonia course. A retrospective analysis of patients’ medical records with myocardial infarction were held from January 1, 2017 until December 31, 2017. Number of patients diagnosed with community-acquired pneumonia is 12 which is equal to 5.3 %, it corresponds to global indicators. 4 of them are men (33 %) and 8 are women (67 %). The number of patients with nosocomial pneumonia was 11, 55 % of men and 45 % of women. Both groups had significant local left ventricular contractility in the form of hypo - and akinesis, but by 8.5% more favorable was observed in the group with nosocomial pneumonia (37.7 % against 41.2 %). Also noteworthy fact is that development complication in the form of heart failure is 3 and above functional by NYHA class is 75 % covered in community-acquired pneumonia and only 37 % nosocomial. General blood test data indicate that the level of severity of inflammatory reactions and toxemia in a group with community-acquired pneumonia is 32 % higher. Correlation analysis showed the following results: direct mean association p = 0.365 adverse outcome of myocardial infarction and community-acquired pneumonia. Revealed a direct weak connection p = 0,090 adverse outcome of myocardial infarction and nosocomial pneumonia.
