Przydatność monitorowania EKG metodą Holtera do oceny ryzyka pacjentów z chorobami układu krążenia
Ambulatoryjne monitorowanie EKG metodą Holtera jest
nieinwazyjnym badaniem o potwierdzonej przydatności
w diagnostyce schorzeń układu krążenia. W ostatnich
latach, dzięki wprowadzeniu nowych analiz możliwych do
zastosowania w czasie badania holterowskiego, metoda
ta stała się przydatna również w ocenie rokowania,
zwłaszcza pacjentów z chorobą niedokrwienną serca.
W niniejszej pracy, na podstawie danych z piśmiennictwa
i własnych obserwacji, opisano przydatność monitorowania
EKG metodą Holtera w przewidywaniu ryzyka u pacjentów
z chorobami układu sercowo-naczyniowego
Przydatność elektrokardiograficznej próby wysiłkowej w ostrych zespołach wieńcowych bez uniesienia odcinka ST
The influence of physical rehabilitation on arterial compliance in patients after myocardial infarction
Background: The aim of this study was to determine the effect of 6-week physical training on
the mechanical properties of the arteries, in patients (pts) after acute myocardial infarction (MI).
Methods: The group under investigation consisted 119 pts after their first acute MI qualified
for the second stage of post-hospital training. Only 64 pts (Group 1) underwent the training
program. The remaining 55 pts (Group 2) could not participate in it. All the pts underwent an
initial exercise test, an ultrasound cardiac scan and a pulse wave velocity (PWV) measurement
by means of the COMPLIOR system. Group 1 underwent cardiac rehabilitation program
according to Model A or B, depending on exercise tolerance at baseline. Then, both groups had
another exercise test and another PWV measurement. Additional PWV measurements were
taken in both groups after 6 months.
Results: Both groups were comparable with respect to demographic data, the site of MI, the
method of treatment, left ventricular function, mean exercise time, the workload attained and
mean PWV values at baseline (12.8 ± 1.6 m/s vs. 12.2 ± 2.7 m/s). In group 1 a significant
increase in exercise capacity was observed: from 6.46 ± 2.7 to 8.95 ± 2.16 MET, and the
PWV values were significantly lowered from 12.8 ± 1.6 to 8.7 ± 1.8 m/s. Group 2 showed only
a slight lowering of PWV from 12.2 ± 2.7 to 10.8 ± 2.3 m/s.
Conclusions: Controlled physical training after MI significantly improves systemic arterial
compliance, probably through improving the endothelial function. (Cardiol J 2007; 14: 366-371
Myocardial infarction in young people
An estimated 6 to 10% of myocardial infarctions occur in patients under the age of 45. Usually
this applies to men, but an increasing prevalence is being observed among women. Atherosclerosis,
often one vessel disease, is the main cause. The presence of classic risk factors affects the
dynamics of coronary artery disease: the strongest risk factor is smoking, regardless of gender.
Environmental influence is also possible. No atherosclerosis is found in 20% of young patients.
In such cases, the most frequent mechanisms of ischemia are: coronary artery embolism
(5%), thrombosis (5%), anomalies (4%) and inflammation or spasm of the vessel. Age is an
independent prognostic factor. Thus the clinical outcome after myocardial infarction is better
in younger than in older patients
