    Wst臋p Celem pracy by艂a ocena za pomoc膮 echokardiograficznego badania przezprze艂ykowego (TEE) czynnik贸w wp艂ywaj膮cych na struktur臋 i elastyczno艣膰 aorty piersiowej. Materia艂 i metody Badaniami obj臋to 102 chorych (26 kobiet) w wieku 57 &plusmn; 10 lat. Na podstawie danych z wywiadu analizowano obecno艣膰 czynnik贸w ryzyka mia偶d偶ycy. U wszystkich chorych wykonano ze wskaza艅 klinicznych badanie TEE, kt贸re rozszerzono o ocen臋 aorty piersiowej. Analizowano 艣rednic臋 aorty, grubo艣膰 b艂ony 艣rodkowo-wewn臋trznej oraz wska藕niki elastyczno艣ci aorty. Wyniki 艢rednica aorty oraz grubo艣膰 b艂ony 艣rodkowo- wewn臋trznej by艂a dodatnio skorelowana z wiekiem (odpowiednio: r = 0,22, p = 0,03; r = 0,27, p = 0,005). Modu艂 Younga i modu艂 elastyczno艣ci &#946; r贸wnie偶 by艂y dodatnio skorelowane z wiekiem (odpowiednio: r = 0,42, p < 0,0001; r = 0,37, p = 0,0002). Chorzy z nadci艣nieniem t臋tniczym charakteryzowali si臋 grubsz膮 b艂on膮 艣rodkowo-wewn臋trzn膮 (0,10 &plusmn; 0,03 vs. 0,13 &plusmn; 0.04, p < 0,05). Zaawansowana mia偶d偶yca wi膮za艂a si臋 ze zwi臋kszon膮 sztywno艣ci膮 jej 艣ciany. Wniosek G艂贸wnymi czynnikami determinuj膮cymi sztywno艣膰 aorty s膮 wiek i zaawansowanie mia偶d偶ycy.Background The purpose of the study was to evaluate by means of transesophageal echocardiography (TEE) the factors affecting the structure and elasticity of the thoracic aorta. Material and methods The study population consisted of 102 patients (26 women) aged 57 &plusmn; 10 years. Information of risk factors of atherosclerosis was obtained by interview. All patients underwent TEE for other reasons, examination was completed by imaging of the thoracic aorta. Results Aortic diameter, the intima-media thickness and distensibility indices were measured. Diameter and thickness of thoracic aorta were positively correlated with age (r = 0.22, p = 0.03; r = 0.27 p = 0.005 respectively). Young&#8217;s modulus and B modulus were also related to age (r = 0.42, p < 0.0001; r = 0.37, p = 0.0002 respectively). Hypertensive subjects had higher wall thickness (0.10 &plusmn; 0.03 vs. 0.13 &plusmn; 0.04, p < 0.05). Advanced atherosclerosis of the aorta was related to higher stiffness of the aorta. Conclusion Aortic elasticity is related mostly to age and atherosclerosis

    Wst臋p: Przerost lewej komory serca jest wa偶nym czynnikiem ryzyka wyst臋powania incydent贸w sercowo-naczyniowych u chorych na nadci艣nienie t臋tnicze. Celem badania by艂o okre艣lenie zale偶no艣ci pomi臋dzy przerostem lewej komory, a zasi臋giem zmian mia偶d偶ycowych w t臋tnicach wie艅cowych ocenianych koronarograficznie. Metody: Badan膮 grup臋 stanowi艂o 197 chorych na nadci艣nienie t臋tnicze, w wieku 53 &plusmn; 9 lat, w tym 65 kobiet bez zawa艂u serca w wywiadzie. Leki obni偶aj膮ce ci艣nienie t臋tnicze otrzymywa艂o 98% badanych os贸b. U 92 os贸b stwierdzono pierwszy stopie艅 nadci艣nienia t臋tniczego, a u 105 os贸b drugi stopie艅. Wska藕niki geometrii lewej komory: 艣rednica jamy lewej komory (LKR), grubo艣膰 przegrody mi臋dzykomorowej (PMK) i tylnej 艣ciany lewej komory (TS) oceniano na podstawie badania echokardiograficznego w prezentacji M, natomiast zasi臋g choroby wie艅cowej oceniono p贸艂ilo艣ciowo poprzez wska藕nik Gensiniego (WG). Wyniki: W analizie dwu zmiennych powierzchnia cia艂a (BSA) korelowa艂a z LKR (r = 0,33, p < 0,0001), TS (r = 0,46, p < 0,0001), PMK (r = 0,40, p < 0,0001), natomiast czas wyst臋powania nadci艣nienia oraz WG korelowa艂y z PMK (r = 0,18, p < 0,05 oraz r = 0,23, p < 0,001) i TS (r = 0,20, p < 0,01 oraz r = 0,23, p < 0,001), lecz nie z LKR. Krokowa wieloczynnikowa analiza regresji wykaza艂a, 偶e LKR zale偶a艂 od BSA (b = 0,25, p < 0,01) (R = 0,37), natomiast TS od BSA (b = 0,39, p < 0,0001), okresu nadci艣nienia (b = 0,24, p < 0,0001) i GS (b = 0,16, p < 0,05)(R = 0,57). W podobny spos贸b PMK by艂o zale偶ne od BSA (b = 0,34, p < 0,001), okresu nadci艣nienia (b = 0,23, p < 0,01) i GS (b = 0,16, p < 0,05) (R= 0,57). Wnioski: Badanie wykaza艂o niezale偶ne powi膮zanie pomi臋dzy zasi臋giem zmian mia偶d偶ycowych w t臋tnicach wie艅cowych a grubo艣ci膮 przegrody mi臋dzykomorowej i tylnej 艣ciany lewej komory. Przerost lewej komory serca jest zar贸wno pod艂o偶em, jak i wyrazem gro藕nych dla 偶ycia proces贸w patofizjologicznych.Background Left ventricular hypertrophy (LVH) is a risk factor for cardiac and vascular events in hypertensive patients (pts). The aim of the study was to evaluate the associaton of echocardiographic indices of LV geometry with the extent of coronary artery disease (CAD) in hypertensive patients catheterized on the basis of symptoms of angina. Methods Study group included 197 pts, age 53 &plusmn; 9 years, 65 women, without significant valvular disease and history of myocardial infarction. LV diastolic diameter (LVD), intraventricular septum (IVS) and posterior wall (PW) thickness were evaluated with M-mode echocardiography. Coronary artery disease extent was assessed with Gensini score (GS). Results In univariate analysis age was not correlated with any of LV geometry indices. Body surface area (BSA) was correlated with LVD (r = 0.33, p < 0.0001), PW (r = 0.46, p < 0.0001), IVS (r = 0.40, p < 0.0001). Both duration of hypertension and GS were correlated with IVS (r = 0.18, p < 0.05 and r = 0.23, p < 0.001) and PW (r = 0.20, p < 0.01 and r = 0.23, p < 0.001 ) but not with LVD. Stepwise multiple regression has shown that LVD was dependent only on BSA (脽 = 0.25, p < 0.01) (R = 0,37). PW was dependent on BSA ((脽 = 0.39, p < 0.0001), hypertension grade (脽 = 0.24, p < 0,0001) and GS (脽 = 0.16, p < 0.05)(R = 0.57). Similarly IVS was related to BSA (脽 = 0.34, p < 0.001), hypertension grade (脽 = 0.23, p < 0.01) and GS (脽 = 0.16, p < 0.05) (R= 0.57). Conclusion The study revealed independent association between left ventricular septum and free wall thickness and the extent of atherosclerotic coronary artery disease in hypertensive patients with angina. That should be further elucidated

    Repeated administration of t-PA and abciximab in a patient with anterior myocardial infarction - a case report: A case of a 40-year-old male with acute anterior myocardial infarction (MI) is presented. Due to the angiographic equipment failure, the patient did not undergo primary angioplasty and received heparin and 100 mg of t-PA. This treatment was associated with clinical and ECG signs of reperfusion, however, 30 minutes after completion of t-PA infusion, the patient developed clinical and ECG signs of re-occlusion. The decision was made to transfer the patient to a catheterisation laboratory for further invasive treatment, however, it was located 200 km from our centre. Because of that, the patient received another dose of 50 mg of t-PA and abciximab before transportaion. Further course was uncomplicated and the patient underwent successful stent implantation in the other centre
