The effect of trimetazidine added to maximal anti-ischemic therapy in patients with advanced coronary artery disease
Background: The purpose of the study was to assess the effect of trimetazidine administered
for 20 days in 56 patients with ischemic heart disease treated with maximal tolerated doses of
anti-ischemic drugs who were not candidates for percutaneous or surgical revascularization.
Methods: The efficacy of trimetazidine was evaluated by comparing exercise testing
parameters before and after treatment, combined with the patient response to a questionnaire
administered at baseline and following the treatment. We evaluated the duration of exercise,
workload, double product, time to the occurrence of ischemic changes in ECG, the number of
leads with diagnostic ST segment depression, and the magnitude of ST segment depression.
Results: After 20 days of trimetazidine treatment, an improvement in exercise testing
parameters was seen in about 50% of patients, and the differences of the mean values were
statistically significant. The patient response to the questionnaire administered following the
treatment indicated a decreased frequency of anginal episodes and an increased exercise
duration to the occurrence of angina in two thirds of patients, less requirement for nitrates in
40% of patients, and increased exercise tolerance in 50% of patients. In patients with subjective
response to treatment, comparison of exercise testing parameters before and after treatment
showed significant increase in the duration of exercise, time to ischemic changes in ECG, and
the degree of ST segment depression during peak exercise. In patients with no subjective
response to treatment, a statistically significant difference was seen in the double product only.
Conclusions: After 20 days of treatment with trimetazidine added to maximal anti-ischemic
treatment in patients with refractory angina, an improvement in exercise testing parameters
and subjective response to treatment were seen in about 40% of patients. In patients with
subjective response to treatment, exercise testing parameters improved significantly compared
to the baseline values

Prediction of left ventricular function in patients after acute myocardial infarction treated with primary angioplasty
Background: Despite a substantial reduction in in-hospital mortality, the long-term outcomes
of patients with acute ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous
transluminal coronary angioplasty (PTCA) remain uncertain. The main causes include
progressive left ventricle (LV) remodelling and impaired LV systolic function with
a decreased ejection fraction (EF). B-type natriuretic peptide testing has recently emerged as an
innovative approach that might enhance the echocardiography-based risk stratification after
STEMI. The aims of the study included long-term echocardiographic assessment of LV function
and remodelling in patients with STEMI treated with PTCA. Additionally, evaluation of
the N-terminal pro-brain natriuretic peptide (NT-proBNP) plasma level utility was performed
to identify factors at patient discharge which would enable to predict LV dysfunction and
remodelling after STEMI at 6-month follow-up.
Methods: Echocardiography was performed in 98 patients at discharge and at 6-month
follow-up. The diameters of the heart chambers and indices of LV systolic and diastolic function
were measured. Plasma levels of NT-proBNP were measured before PTCA and at 6 months.
Results: Primary PTCA successfully restored normal epicardial blood flow in the infarctrelated
Artery (IRA) in 96 patients. At 6 months preserved LV systolic function (median EF
47.5%), decreased LV diastolic function with relaxation abnormalities (E/A < 1.0 and
IVRT > 105 ms) and no significant increase in left ventricular end-diastolic diameter (LVEDD) were observed in study population. Multivariate analysis identified low baseline NT-proBNP
level, low peak creatine phosphokinase (CPKmax) activity and high EF at discharge as powerful
independent predictors of preserved EF at 6 months. LVEDD at discharge, baseline NT-proBNP
level and CPKmax correlated with LVEDD at 6 months in the multiple regression model. In
multivariate analysis a high NT-proBNP level on admission and low LVEDD at discharge
were independent predictors of LVEDD change. Patient groups with reperfusion obtained
3.2 h from symptom onset (the median delay) did not differ with respect to IRA blood
flow, infarct size assessed as CPKmax and LVEDD at 6 months. A significant increase in EF
was noted only in patients with chest pain duration < 3.2 h. Time-to-treatment correlated with
NT-proBNP level at 6 months.
Conclusions: Successful primary PTCA in STEMI influences LV systolic function improvement
and effectively prevents LV remodelling at the 6-month follow-up. Low baseline
NT-proBNP, low CPKmax and high EF at discharge are powerful independent predictors of
preserved EF after 6 months. A high NT-proBNP level on admission and low LVEDD at
discharge predict a propensity for LV remodelling. A prolonged time-to-treatment of STEMI
results in a lack of significant long-term improvement in LV systolic function and does not seem
to have an impact on the occurrence of LV remodelling
One-year outcomes of left main coronary artery stenting in patients with cardiogenic shock
Background: The high in-hospital mortality of patients with cardiogenic shock is being
reduced thanks to coronary interventions. The aim of the study was to evaluate the outcomes of
angioplasty and stenting in patients with cardiogenic shock caused by left main coronary
artery (LMCA) disease.
Methods: A group of 71 consecutive patients managed for LMCA disease in an emergency
setting (38 patients in cardiogenic shock and 33 without shock symptoms) were followed up
clinically and angiographically for one year. Periprocedural and late mortality was assessed as
well as the incidence of restenosis and coronary re-interventions.
Results: There were 17 deaths in the study population (23.9%). One-year survival in the
subgroup with cardiogenic shock was 57.9% (22 patients) with 15 periprocedural deaths and
1 death 3 months after the procedure. Restenosis and associated target lesion revascularization
were documented in 5 patients (29.4%) with and 4 patients (16.0%) without cardiogenic
shock. Multivariate analysis revealed the following independent predictors of cardiogenic shock
in patients undergoing emergency LMCA angioplasty: STEMI as the reason for intervention
(OR 14.1; 95% CI 3.71–53.7; p < 0.0002) and a small minimal lumen diameter before the
procedure (OR 0.43; 95% CI 0.2–0.93; p < 0.04). The only independent predictor of the death
in patients with cardiogenic shock was a small minimal lumen diameter after the procedure
(OR 0.31; 95% CI 0.1–0.99, p < 0.05).
Conclusions: High mortality was observed in the study population, especially in the subgroup
with cardiogenic shock. Most deaths were periprocedural. Because of the high rate of restenosis,
periodical angiographic follow-up is necessary, preferably twice in the first 6 months after stent
implantation. (Cardiol J 2007; 14: 67–75
Angioplastyka t臋tnicy wie艅cowej z wykorzystaniem aterektomii rotacyjnej jako metody leczenia w "trudnych przypadkach"
W niniejszej pracy przedstawiono przypadek 56-letniego pacjenta z ostrym zespo艂em wie艅cowym
powik艂anym wstrz膮sem kardiogennym. U chorego wykonano angioplastyk臋 ga艂臋zi mi臋dzykomorowej przedniej z implantacj膮 stentu oraz angioplastyk臋 balonow膮 ga艂臋zi okalaj膮cej.
Ze wzgl臋du na z艂o偶one zw臋偶enie z obecno艣ci膮 zwapnie艅 nie uda艂o si臋 wykona膰 zabiegu poszerzenia
prawej t臋tnicy wie艅cowej. Po up艂ywie 3 miesi臋cy od interwencji pacjenta ponownie
przyj臋to do kliniki z powodu nasilenia dolegliwo艣ci stenokardialnych. W wykonanej koronarografii
stwierdzono dobry efekt w miejscu poszerzanych zw臋偶e艅. Ponowna pr贸ba angioplastyki
prawej t臋tnicy wie艅cowej okaza艂a si臋 nieskuteczna. Z tego powodu wykonano zabieg rotablacji
w celu pokonania miejsca zw臋偶enia oraz usuni臋cia nadmiaru blaszki mia偶d偶ycowej z nast臋pcz膮 implantacj膮 dw贸ch stent贸w. Po zastosowanym leczeniu pacjent nie odczuwa艂 dolegliwo艣ci stenokardialnych ani objaw贸w niewydolno艣ci serca. (Folia Cardiologica Excerpta 2007;

Percutaneous coronary angioplasty in elderly patients: Assessment of in-hospital outcomes
Background: We aimed to assess in-hospital outcomes of percutaneous transluminal coronary
angioplasty (PTCA) in elderly subjects.
Methods: A total of 1000 consecutive patients, who had all been admitted for interventional
treatment of symptomatic coronary artery disease, were retrospectively analysed.
Results: Elderly patients (≥ 70 years of age) were more likely to be diabetic, hypertensive and
of female gender. They more frequently were diagnosed with chronic heart failure as well as
prior stroke. Significantly higher proportions of the elderly population presented with
cardiogenic shock and underwent PTCA as a result of acute coronary syndromes. Multivessel
coronary disease affected a large majority of senior patients. Although stenting dominated in
both age groups, balloon angioplasty was relatively more frequently applied in the elderly.
Coronary angioplasty in elderly patients was associated with fewer direct stenting procedures,
longer exposure to X-rays and a higher volume of the contrast medium. The efficacy of intervention,
assessed according to clinical and angiographic criteria, was high in both groups,
although revascularisation was significantly less complete while crude in-hospital mortality
higher in the elderly group. Advanced age remained an independent predictor of both increased
in-hospital mortality and longer exposure to X-rays after an adjustment for the baseline
characteristics in multivariable analyses.
Conclusions: Despite frequent comorbidities and more extensive coronary athersoclerosis,
a high rate of procedural success was achieved in the elderly population who underwent PTCA.
However, after an adjustment for the baseline characteristics advanced age was still associated
with a less favourable in-hospital outcome and a higher degree of procedural complexity.

P贸藕na zakrzepica w stencie powlekanym rapamycyn膮
Stentowanie t臋tnic wie艅cowych jest rutynowym zabiegiem, kt贸ry stosuje si臋 podczas przezsk贸rnej
rewaskularyzacji serca. Coraz cz臋艣ciej wykonuje si臋 implantowanie kilku rodzaj贸w stent贸w
do tej samej t臋tnicy wie艅cowej.
W niniejszej pracy przedstawiono przypadek 57-letniego pacjenta z ostrym zawa艂em serca
艣ciany przedniej, u kt贸rego po 6 miesi膮cach od implantacji 2 stent贸w (jeden stent pokrywany
lekiem antyproliferacyjnym, drugi stent standardowy) wyst膮pi艂a p贸藕na zakrzepica w stencie
powlekanym oraz rozlana restenoza w stencie standardowym. U chorego wykonano pierwotn膮
angioplastyk臋 balonow膮, a po 4 tygodniach w miejsce 2 stent贸w wszczepiono stent powlekany
Cypher. W kontrolnej koronarografii, wykonanej po 6 miesi膮cach od implantacji, nie wykazano
restenozy. (Folia Cardiol. 2004; 11: 309–314
