[Gender differences in sport-adaptation of intramural coronary resistance arteries]

TÖRÖK Marianna

[Biomechanical and functional remodeling of coronary resistance arteries in physiological left ventricular hypertrophy has not been analyzed yet, and the possible sex differences are unknown. We aimed to study the biomechanics and function of these arteries during an exercise intervention. Wistar rats were divided into four groups: male and female sedentary controls (MSe and FSe) and male and female animals undergoing a 12-week intensive swim training programme (MEx and FEx). After the training sessions, LV morphology and function were checked by echocardiography, the coronary artery biomechanics and function were examined by pressure arteriography. Elastica remodeling was studied in resorcin-stained histological sections. The female animals had enhanced heart weight/body weight ratio compared to male rats. A similar outer radius and reduced inner radius resulted in an elevated wall-to-lumen ratio in the MEx and FEx animals compared to the sedentary controls. The wall elastic moduli increased in the MEx and FEx rats. The spontaneous tone and TxA2 agonist-induced tone was raised only in ExF animals, whereas the endotheliumdependent relaxation became more effective in ExM rats. Arteries of ExF rats had stronger contraction, whereas arteries of ExM animals had improved dilation. Range of coronary vascular reactivity increased in both exercised male and female rats, but its mechanism was different depending on sex. According to our results the coronary arterioles adapted to an elevated load during long-term exercise and this adaptation depended on sex. The observed sex differences in the biomechanics and function of the coronary resistance arteries of rats may contribute to better understanding of the physiological and pathological function of these arteries in active and retired athletes.]

[The efficiency of angiotensin receptor blocker/neprilysin inhibitor (ARNi) treatment in heart failure 2020 ARNI, VIDI, VICI…]

VÁRALLYAY Zoltán

[A new compound ARNi (valsartan/sacubitril) – as a member of a new pharmacoterapeutic group – has several clinical evidences almost in the whole spectrum of heart failure, especially in case of reduced left ventricular ejection fraction and hypertension. The most important and essential evidence based studies and the efficiency of the treatment with ARNi in heart failure have been demonstrated in this overview. Due to the favorable results of the studies the recommendations of ARNi indication are increasingly dominant in the clinical guidelines. The usage provides effective, safe therapeutic help for the poor life expectancy heart failure patients in the everyday clinical practice. The treatment is already available in Hungary.]

[With the development of the equipments of extracorporeal circulation, international studies underline reducing the amount of filling fluid. Our retrospective study was conducted at the Heart Surgery Clinic of the University of Pécs between 1 January 2017 - 31 December 2017 with ECC cardiac operated patients. During the document analysis, data were collected from 157 patients between 50 and 70 years who underwent CAB surgery. They were classified into Low- (n=47) and Standard-prime (n=110) group. Medium negative correlation (r=-0.28; p<0.001) was found between prime/body surface area and haematocrit during last perfusion. As inflammatory parameter, the last measured CRP values were 36.00 mg/l (low) vs. 70.62 mg/l (standard). Our research justified the use of low-prime during ECC. The implementation of the method requires the scientific advancement of perfusionists, the preparation of national protocols and the improvement of the perfusionist’s training and legal background. ]

[The ACE2-Ang(1-7)-Mas axis as a new option for lowering blood pressure]

KÉKES Ede

[The ACE2-Ang(1-7)-Mas axis counterbalances the ACE/Ang II-AT1R axis in our body in order to maintain normal homeostasis. During the Covid-19 pandemic, this protective system came to the fore again and its beneficial effects on the cardiovascular-metabolic system, including the significant antihypertensive effect, are being clarified. In our brief summary, we analyze the essential aspects of this research.]

[Wearing a face mask: effect on a doctor – patient relationship. Complicating factors and their compensations]

VONYIK Gabriella, FARKAS Martin, TURNER Andrea, FINTA Ervin, BORSZÉKI Judit

[Wearing face masks plays an important role to effectively decrease the chance of transmitting respiratory diseases. Face masks commonly worn during the Covid-19 pandemic to shield the mouth and the nose, cover about 60- 70% of the area of the face that is crucial for the effective verbal and nonverbal communication and perception of mental states. Face masks may complicate social interaction especially in the medical setting where communication skills and doctor-patient relationship are essential to primary care consultations. Literature was reviewed on the impact of such face masks on effective doctor and patient communication as well as useful alternative ways are suggested to compensate them in order to maintain the effective doctor-patient interaction.]
