REZIME

Infarkt miokarda je najteži oblik bolesti srca, ima veliko značenje u savremenoj medicini zbog visokog
morbiditeta a samim tim i mortaliteta.

Smrtnost u akutnom infarktu miokarda iznosi oko 30%, pri čemu se više od polovine smrti događa pre nego što
oboleli stignu do bolnice. Premda se preživljenje nakon hospitalizacije u poslednjih dvadeset godina poboljšalo, ipak
dodatnih 5-10% preživelih umire u prvoj godini nakon infarkta srca. Kod bolesnika koji se oporave, postoji trajan
rizik od povedane smrtnosti i novih infarkta. Primenjena metoda je pradenje rada zdravog i obolelog srca putem
EKG-a. Elektrokardiogram (EKG) je crtež kojeg proizvodi elektrokardiograf, uređaj koji beleži električnu aktivnost
srca u vremenu. Analiza različitih valova i vektora depolarizacije i repolarizacije dovodi do značajnih podataka u
dijagnostici bolesti.

Prilikom ispitivanja ustanovljeni su razni uzroci koji dovode do srčanog udara . Najvažniji su : povišen krvni
pritisak, povišene masnode, pušenje, šederna bolest, debljina , nasledni faktor i neočekivani veliki stres. Na našim
prostorima poslednjih godina uočen je sve vedi broj obolelih od infrkta i drugih srčanih oboljenja što je
propradeno svim naučnoistraživačkim i statističkim podatcima koji kao glavni razlog navode loš životni standard i
„veliki broj stresnih situacija“. Osobe koje vode miran i lagodan život su u manjoj opasnosti od raznih oboljenja i
srčanih udara.

SUMMARY
Myocardial infarction is the most severe form of cardiac disease; due to its high morbidity, and consequently high
mortality rates, it has great impact in modern medicine.

Mortality in acute myocardial infarction is approximately 30%, where more than half deaths occur before patients
reach hospital. Though survival rates after hospitalization have improved over the past 20 years, another 5-10% of
survivors die during the first year after myocardial infarction. In patients who recover, there is permanent risk for
increased mortality and new infarctions. Practical method is observing action of healthy and diseased heart using
ECG. Electrocardiogram (ECG) is drawing produced by electrocardiograph, the device which records electric activity
of heart over time. By analyzing different waves and vectors produced by depolarization and repolarization,
significant data are obtained which may be useful for diagnosis of the disease.
During the research, the variety of causes have been determined that lead to heart attack. The most important
are: elevated blood pressure, increased levels of fat, smoking, diabetes, obesity, genetic causes, and unexpected
major stress. In our surroundings, during the last couple of years, the increasing number of individuals suffering
from myocardial infarction and other heart diseases is observed, which is accompanied by scientific and statistical
evidence which suggest low quality of life and “large number of stress situations” as major cause. Persons who live
calm and comfortable life are at lower risk to develop different diseases and heart attacks.Key words : heart,
