Sex- and/or ethnic-appropriate echocardiographic reference values are indicated for many measurements of LA and LV size, LV mass, and EF. Reference values for LV volumes and mass also differ across the age range.
Background / Aim. Well-organized cardiovascular rehabilitation (CVR) reduces
cardiovascular burden by influencing cardiovascular risk factors, improving
the quality of life and reducing mortality and hospital readmission.
However, its effects on hemodynamic status are largely unknown. The aim of
our study was to evaluate the influence of three-week CVR program on
hemodynamic status and to investigate if there is a correlation between
physical strain tolerance and hemodynamic parameters measured by impedance
cardiography (ICG) before and after CVR program in patients with coronary
artery disease. Methods. Fifty-two patients attended a three-week CVR
program. At the beginning and at the end of rehabilitation program
laboratory tests, exercise stress tests (EST) and ICG measurements were
taken. Results. Patients showed better strain tolerance on the second
exercise stress test (EST2) by achieving higher strain level (Z=2,315;
p=0,021) and longer duration of test (Z=2,305; p=0,021). There was a strong
positive correlation between the level of EST2 and cardiac output (CO)
(r=0,538; p<0,001) and stroke volume (SV) (r=0,380; p=0,017) on the second
ICG (ICG2). Also, there was a strong negative correlation between EST2 level
and systemic vascular resistance (SVR) (r=-0,472; p=0,002) and SVR index
(SSVRI) (r=-0,407; p=0,010) on ICG2. There was a strong positive correlation
between EST2 duration and CO (r=0.517; p=0.001) as well as between EST2
duration and SV (r=0.340; p=0.034), and a strong negative correlation
between EST2 duration and SVR (r=-0.504; p=0.001) as well as between EST2
duration and SVRI (r=-0.448; p=0.004), according to ICG2. Conclusion. Our
study showed that a well-designed CVR program can lead to better physical
strain tolerance. Furthermore, CVR led to a significant positive correlation
between EST and cardiac output as well as between EST and stroke volume
measured by ICG. On the other hand, there was a significant negative
correlation between EST and vascular related parameters according to ICG at
the end of the CVR program.
UvodKardiorenalni sindrom se definiše kao patofiziološki poremećaj funkcije srca i bubrega, u kome akutni ili hronični poremećaj funkcije jednog organa podstiče akutni ili hronični poremećaj drugog organa (1-5).Razlikujemo pet tipova kardio-renalnog sindroma, a u kardio-renalnom sindromu tip 2 hrončni poremećaj funkcije srca za posledicu ima hronični poremećaj funkcije bubrega (1-5). Zbog smanjenog srčanog rada i smanjene zapremine arterijske krvi koja obezbeđuje perfuziju bubrega, hronična zastojna srčana slabost dovodi do stalnog i progresivnog opadanja funkcije bubrega (1-5).

Uvod. Lečenje višesudovne koronarne bolesti primenom perkutane koronarne intervencije (PCI) pokazalo je zadovoljavajući kratkoročni, ali inferiorniji dugoročni rezultat u odnosu na aortokoronarnu bajpas operaciju (CABG).
ABSTRACT
Objective. Previous experience in the treatment of multivessel coronary artery disease using PCI showed satisfactory short-term, but inferior long-term results in comparison to CABG. Certain groups of patients with multi-vessel disease treated with PCI may have long-term results equal to CABG. In the decision making process there is
