[Atherosclerosis: an ancient process in a new interpretation]

REIBER István

[The progress of atherosclerosis starts in childhood and lasts until the body dies. Most cardiovascular diseases and deaths can be traced back to atherosclerotic vascular changes. The process is thousands of years old, but its complex pathophysiology becomes recognized and realised only nowadays. Based on the evidence available today, atherosclerosis is such a chronic inflammatory disease of large- and medium-sized arteries, which is characterized by lipoproteins and immune cells transformed through oxidative and other changes and subendothelial accumulation of extracellular matrix. Innate and adaptive immunity provide a complex regulating system of atherogenesis, which while directing specifically the pro-atherogenic inflammatory and atheroprotective anti-inflammatory processes intensify plaque progression or even stabilize them respectively. With our growing knowledge about the pathology of atherogenesis, we can further improve the identification of cardiovascular risk conditions and apply more personalized therapeutic strategies.]

SZÁNTÓ Ildikó, SÁNDOR Balázs, KATONA Krisztián, NAGY Máté, JUHÁSZ Annamária, BALÁS István

[The evaluation of hand dexterity is an important marker for the success of DBS (deep brain stimulation) operation in patients with Parkinson’s disease. In this study we applied a simple, semiquantitative optical dental plaque staining technique for the evaluation of the hand dexterity. Ten patient with Parkinson’s disease were involved in the study. After dental students aided tooth brushing, bacterial dental deposits (plaque) were stained then photographed, and quantified under standard conditions before and after DBS surgery. Our results showed a significant decrease in dental plaque deposits after DBS operation. This simple technique seems to be a routinely applicable marker for the evaluation of the hand dexterity. Our future plans is repeating the previous experiement on a higher number of cases.]

[The atherosclerosis can not only be prevented, but also can be cured ]

MÁRK László

[The process of atherosclerosis nowadays plays an important role in the health care not just as a major cause of the most common cardiovascular diseases which lead to death, but also as a major factor in the loss of age-related elasticity in the blood vessels. Over the past two decades, large studies have shown that the treatment of high cholesterol levels can reduce the frequency of cardiovascular events and death and have confirmed the ability to reduce the already existing atherosclerotic plaque, which is almost unique in pharmacotherapy. Using lipid lowering therapy, if we do it properly, we can not only prevent vascular events, but can also cure atherosclerosis. Currently there are three drug groups (statins, ezetimibe and PCSK9- inhibitors), which have complete evidence that their use can reduce the number of cardiovascular events and plaque regression can be achieved. Despite many convincing clinical trials, lipid-lowering therapy is on the cardiovascular prevention palette in the just tolerated or forced applied category. In order to take advantage of its potentials at an appropriate level, as doctors, we have to approach to it by considering its importance. We should communicate to our patients that it’s about a life-long treatment, which not only can reduce the possibility of cardiovascular events, but also can slow down the aging process of the arteries. ]

UFUK Emre, TASKIN Gunes, IREM Pinar, FURUZAN Kokturk, ESENGUL Liman, ORHAN Yağiz

Purpose - In cancer patients, an ischemic stroke can be seen as both a direct effect of cancer and a complication of treatment. This condition can negatively affect the follow-up and treatment of these patients. For this research, we aimed to evaluate the clinical features, stroke types and etiological features of ischemic stroke patients with histories of cancer or found to have cancer during the aetiological investigation. Materials and methods - We retrospectively evaluated 100 patients (57 males, 43 females) who were hospitalized with acute stroke and determined to have the presence of cancer or a cancer history during the aetiological investigation between 2011 and 2016. All the demographic features, stroke types and localizations, National Institutes of Health Stroke Scale (NIHSS) scores, Rankin Scale scores, durations of cancer and cancer treatments were recorded. Results - The mean age of the patients was 67.07 ± 10.9 years old, the median NIHSS score was 5, and the median Rankin Scale score was 4. While 79% of patients had ischemic stroke risk factors, 21% did not. Atherosclerotic stroke was the most common stroke type (49%, n=49) and cryptogenic strokes were detected in 21% (n=21). In addition, 63% of the patients had chronic cancer (later than 6 months), 31% of the patients had recent cancer histories (less than 6 months), and 29% of the patients had metastases. Among all the malignancies, lung cancer (n=23), gastrointestinal cancer (n=20) and gynaecological-breast cancer (n=16) were the three most common. Moreover, 37% of the patients underwent chemotherapy, 29% underwent radiotherapy, and 88% of the patients had Carotid/Vertebral Doppler USG abnormalities. Conclusion - Similar to what is stated in the literature, an atherosclerotic stroke was the most common type of stroke in the cancer patients. Stroke risk factors were not detected in 21% of the patients, and in the majority of the patients, atherosclerotic changes in the carotid artery were observed in the Doppler examinations. In the aetiology and prognosis of ischemic stroke, it is important to keep in mind the existence of cancer in addition to the classical stroke risk factors.

[Thought about renovascular hypertension by a special case report]

GAJDÁN Nikolett, LÉGRÁDY Péter, BAJCSI Dóra, MORVAY Zita, NAGY Endre, LETOHA Annamária, KYPROS Constantinou, FEJES Imola, SONKODI Sándor, ÁBRAHÁM György

[Renovascular hypertension is a well-known form of secunder hypertension. Two thirds of cases are caused by atherosclerotic plaque and one third are caused by fibromuscular dysplasia. The prevalence of it is less than 1%. Digital subtraction angiography is considered the goldstandard diagnostic method. The 58-year old female patient was hospitalized with resistant hypertension. Duplex ultrasonography showed fibromuscular stenosis the in left renal artery. Percutaneous transluminal angioplasty and stenting were performed. Her blood pressure normalized. The patient did not attend the control examinations. Next time in 2001, she was referred to our emergency department with increased blood pressure of 210/140 mmHg. Following control ultrasonography angiography showed total occlusion of the left renal artery and significant stenosis of the right renal artery. Left nephrectomy was necessary due to shrunken kidney and dilatation and stenting of the right renal artery. The blood pressure normalized again. Since 2004 until 2014 despite of the regular visits, we detected in stent restenosis of the right renal artery almost in each year. Even so, renal function was preserved all the time. In autumn of 2014, the patient suffered severe stroke, and few months later at the age of 74 she died. There are many open questions to discus concerning the right treatment of renovascular hypertension yet. Even so by performing 12 intravascular interventions we could ensure her acceptable quality of life for 16 years.]

[Mazes and compass in prognostic value of cardiovascular risk factors]

KÉKES Ede, KISS István

[The risk assessment of cardiovascular disease is dispensable in everyday practice, because this disease-group gives the high-est death rates all over the world - in developed countries, in Central European Region, including Hungary. Based on reliable surveys world side, we need in addition to coronary heart disease, stroke has been reckoned today to peripheral vascular disease, type-2 diabetes, and chronic kidney diseases as well. It seems useful to the new name i.e., atherosclerotic cardiovascular diseases. It stands as smoking, hypertension, dyslipidemia risk factors among this group of diseases in the background, but more and more importance is given to visceral obesity, physical inactivity, alcohol consumption and psycho-social status. It has to count with the fact that the individual factors together and appear further worsen to mortality rate. The greatest interference arises because the cardiovascular risk estimation proposed by embodiments of non-uniform principles. Undoubtedly, the resolution of ACC/AHA 2010 was the first correct compass, because the classification and utility values of the factors precisely regulated. But in addition, it is essential that in the risk assessment not only the “global estimation” (tables, other forms) will be conducted, but also other important parameters characterizing the extended factors (vascular structure, obesity, psycho-social status, etc.) - set schedule and regulations - acting on to be carried out. We presented in cardiovascular risk assessment methodology and the most profitable methods of estimation based on the preventive guidelines, extern opinions generally accepted now and own experiences. We propose to modify the risk assessment me-thod.]

[Angiotensin-converting enyzme inhibitors before and after myocardial infarction]

TOMCSÁNYI János

[In this review current knowledge related to the coronary atherosclerosis and angiotensin-enzym inhibitor is discussed. The earlier recognition to the effect of ACE inhibitors and ARBs to slow or reverse left ventricular remodelling is well known and accepted but the effect of these drugs on the atherosclerotic process itself may be aqual important. The focus should be now how to treat the early phase of coronary atherosclerosis, how to treat safety the hypertensive patient in the setting of coronary stenosis, how to treat the acute myocardial infarction’s patient with renal failure, and at least how to improve the long-time adherence in the primer and secunder prevention too.]

[The positive additive effect of rosuvastatin on platelet aggregation parameters in patients with cerebrovascular disease]

FEHÉR Gergely

[Statin therapy is the cornerstone of anti-atherosclerotic treatment, and it considered obligatory in the secondary prevention of atherosclerotic diseases. Rosuvastatin is well-known and efficacious lipid-lowering agent and seems to have benefitial antiplatelet efficacy and anti-inflammatory profile. The aim of our study was to determined the antiplatelet effect of 20 mg rosuvastatin (Xeter®, Richter Gedeon Nyrt.) in clopidogrel treated cerebrovascular patients. 20 patients with documented ischaemic cerebrovascular events and on 75 mg clopidogrel daily treatment were included in our study. 20 mg generic rosuvastatin significantly decreased total cholesterol (5.67 vs. 3.99 mmol/l, p<0.05), low-density lipoprotein (3.11 vs. 1.92 mmol/l, p<0.05) and trigliceride levels (1.75 vs. 1.29 mmol/l, p<0.05), and there was a non-significant high-density lipoprotein increasing (1.28 vs. 1.36 mmol/l, p=0.09) and high-sensitive C-reactive protein level decreasing tendency (3.35 vs. 2.99 mg/l, p=0.07). Rosu­vastatin treatment significantly decreased ADP 5 µM (46.15 vs. 31.35%) and collagen 2 mg/ml (68.62 vs. 52.22%) induced platelet aggregation (p<0.05). 20 mg rosuvastatin has a robust antilipaemic profile with benefitial additive effect on agonist induced platelet aggregation.]

[Current questions on Pneumococcus infections: cardiovascular complications, cardiotoxicity and new opportunities for prevention among elderly people]

LUDWIG Endre

[The respiratory tract infections, first of all severe pneumonia are associated with severe cardiovascular adverse events the significance of which that had not been recognised so far. Among the adverse events, the development of acute coronaria syndromes, heart failure, arrhythimias are the most important ones leading to significatly higher mortality even after several years. In the development of acute coronaria syndrome , the proinflammatory activites play the cenral role leading to the instability of coronaria plaques and plaque rupture associated with formation of platelet thrombi. The constriction of coronariae, peripherial vasodilatation and hypoxia also contribute to the deleterius complications. The role of pneumococci in this process seems to be especially significant since this pathogen exhibit a unique direct cardiotoxic effect, namely directly invades the myocardium and produce cardiotoxic substances. As a consequence, impairement of cardiomyocite function and contractility and formation of microscopic lesions in which later collagen deposition and long-term cardiac scarring can be detected. These pathological processes are developed despite of antibiotic treatment, consequently, vaccination against pneumococcal infection seems to be the only method for efficacious prevention of the myocardium damage and cardiovascular adverse events. According to the results of the CAPITA study, the conjugate polisaccharide vaccine decrease the number of pneumococcal pneumonia and invasive pneumococcal infections by 45 and 75% resp. in the elderly population. The recognition of the direct and indirect role of pneumococci in the development of early and late cardiovascluar adverse events gives a new aspect of the beneficial effect of efficacious vaccination.]
