[Predictive factors for ischemic heart disease, diabetes mellitus and chronic kidney disease among hypertensive patients based on the data of the Hungarian Hypertension Registry 2011-2013-2015. Part I. Hypertensive population aged 35 to 64 years]

KÉKES Ede, PAKSY András, SZEGEDI János, JÁRAI Zoltán

[The association of hypertension with ischemic heart disease, diabetes and chronic kidney disease is the greatest therapeutic challenge because these associations significantly increase mortality and deteriorate life expectancy. It is important for the clinician to clarify the predictive factors of each association for successful prevention or slowing the progression of diseases. According to the database of the Hungarian Hypertension Registry 2011-2013-2015, 11,137 men and 11,112 women with hypertension and comorbidities (CHD, diabetes, CKD) aged between 35 and 64 were analyzed for the purpose of assessing the predictive value of the traditional risk factors in co-morbidity. We analyzed the predictive weight of each variable with single- and multi-variable stepwise logistic regression, and reported Odds ratio (OR, odds ratio). In patients with hypertension aged 35-64 (male / female), the prevalence of CHD was 41.6% / 35.8%, diabetes 27.1% / 23% and KVB 16.2% / 33.8%, respectively. The chance of developing CHD is highest in hypertensive individuals (male/female) who have diabetes (OR 1.30/1.48), who are obese (OR 1.22/1.21), who smoke (OR 1.50/1.51), and whose blood pressure >140/90 mmHg (OR 1.23/1.29). The dominant predictive factors of type 2 diabetes are obesity (visceral obesity) (OR 1.46/1.49), low HDL cholesterol (OR 1.32/1.35), and high triglyceride levels (OR 1.20/1.42); in women the uric acid level also showed high odds ratio (OR 1.39). There is a significant chance of developing chronic kidney disease in hypertension in both sexes, if abnormal uric acid levels (OR 1.73/1.46) and inadequate treatment of high blood pressure (>140Hgmm SBP) (OR 1.43/1.19) are present. In women, the abnormal triglyceride level) also showed a high odd (OR 1.81).]

Risk factors for ischemic stroke and stroke subtypes in patients with chronic kidney disease

GÜLER Siber, NAKUS Engin, UTKU Ufuk

Background - The aim of this study was to compare ischemic stroke subtypes with the effects of risk factors, the relationship between grades of kidney disease and the severity of stroke subtypes. Methods - The current study was designed retrospectively and performed with data of patients who were hospitalised due to ischemic stroke. We included 198 subjects who were diagnosed with ischemic stroke of Grade 3 and above with chronic kidney disease. Results - In our study were reported advanced age, coronary artery disease, moderate kidney disease as the most frequent risk factors for cardioembolic etiology. Hypertension, hyperlipidemia, smoking and alcohol consumption were the most frequent risk factors for large-artery disease. Female sex and anaemia were the most frequent risk factors for small-vessel disease. Dialysis and severe kidney disease were the most frequent risk factors in unknown etiologies, while male sex, diabetes mellitus, prior stroke and mild kidney disease were the most frequent risk factors for other etiologies. National Institute of Health Stroke Scale (NIHSS) scores were lower for small-vessel disease compared with other etiologies. This relation was statistically significant (p=0.002). Conclusion - In order to improve the prognosis in ischemic stroke with chronic kidney disease, the risk factors have to be recognised and the treatment options must be modified according to those risk factors.

[GLP-1 receptor agonists in the treatment of type 2 diabetes]

WINKLER Gábor

[The glucagon-like peptide (GLP)-1 receptor agonists and somewhat later, the sodium-glucose cotransporter (SGLT) -2 inhibitors have brought new perspectives in the antihyperglycemic treatment of type 2 diabetes. The article overviews clinicopharmacologic characteristics of the GLP-1 receptor agonist group, their glycemic and non-glycemic effects, results of the cardiovascular endpoint studies as well as their place in the recent therapeutic guidelines. It is proven, that both glycemic and weight reducing effect is greater of the long-acting (non-prandial) coumpounds as compared to that of the short acting (prandial) derivates, further, that in studies with cardiovascular endpoints they reduced the relative risk of the composite endpoint of non-fatal myocardial infarct, non-fatal stroke and cardiovascular death. Due to the favolurable glycemic and non-glycemic properties their use is advised already in the early course of type 2 diabetes, as combination of the metformin therapy.]

[Treatment of painful diabetic polyneuropathy ]

KIS János Tibor

[Diabetic polyneuropathy can be present in up to 20-60% of diabetics, making it the most common complication of diabetes, but it is often undiagnosed. The diagnosis is mainly based on symptoms, but also several test options are available. For the prevention of neuropathy, long-term control of glycemic parameters is the most important. The pain caused by diabetic polyneuropathy affects 13-26% of diabetics. After the diagnosis, there are a number of treatment options that can be divided into causal and symptomatic therapy. The author summarizes therapeutic options from a practical point of view. ]

[Serum uric acid level in hypertension. Domestic experience based on the data of the Hungarian Hypertension Registry 2011., 2013. and 2015. Part III. - Relation of uric acid to clinical and laboratory characteristics]

KÉKES Ede, PAKSY András, ALFÖLDI Sándor

[2013. and 2015, we examined the correlation between the serum uric acid level and blood pressure, target blood pressure, prevalence of ISH and other diseases associated to high blood pressure used trend analysis and linear regression in 22,668 hypertensive men (mean age 60.8 years) and 24,684 hypertensive women (mean age 64.1 years). We have extended the correlation analysis to metabolic factors (BMI, abdominal circumference, lipid profile, blood sugar) and kidney function. Significant correlation was found between SH level and systolic and diastolic blood pressure as well as target blood pressure. There was a significant correlation between SH level and metabolic parameters (abdominal circumference, BMI, total cholesterol, HDL cholesterol, triglyceride, fasting blood sugar) and in hyperuricemia the prevalence of metabolic syndrome was higher. As the level of SH increases, the prevalence of hypertension-related KVB, ISZB and diabetes have increased. The closest correlation between uric acid levels and chronic kidney disease was in women and between the uric acid levels and ischemic heart disease in men. ur analysis supports the international declaration that hyperuricemia is an independent cardiovascular, metabolic and renal risk factor.]

Effects of CHADS2 score, echocardiographic and haematologic parameters on stroke severity and prognosis in patients with stroke due to nonvalvular atrial fibrillation

AYNACI Ozer, TEKATAS Aslan, AYNACI Gülden, KEHAYA Sezgin, UTKU Ufuk

Introduction - The aim of this study is to evaluate utility of CHADS2 score to estimate stroke severity and prognosis in patients with ischemic stroke due to non-valvular atrial fibrillation (AF) in addition to evaluate effects of hematologic and echocardiographic findings on stroke severity and prognosis. Methods - This prospective study included 156 ischemic stroke cases due to non-valvular AF in neurology ward of Trakya University Medical School between March 2013-March 2015. National Institute of Health Stroke (NIHS) score was used to evaluate severity of stroke at admission. Carotid and vertebral Doppler ultrasonography findings, brain computed tomography (CT) and magnetic resonance imaging (MRI) of the cases were evaluated. Left atrial diameter and ejection fraction (EF) values were measured. CHADS2 score was calculated. Modified Rankin Scale was used to rate the degree of dependence. Effects of age and sex of the patients, presence of diabetes mellitus (DM), Congestive Heart Failure (CHF), Cerebrovascular Disease (CVD) and C-reactive protein (CRP) levels on CHADS2, NIHS, and mRS were evaluated. Results - In patients with age ≥75, mean NIHS score was 3.3 points and mean mRS score was 1.02 points higher, than in patient below 75 years of age. Compared with the mild risk group, cases in the high risk group had older age, higher serum D-dimer, fibrinogen and CRP levels and lower EF. A positive relation was detected between stroke severity and Hemorrhagic Transformation (HT), previous CVD history, and presence of CHF. A significant association was found between increased stroke severity and Early Neurological Deterioration (END) development. Older age, higher serum fibrinogen, D-dimer, CRP and lower EF values were associated with poor prognosis. History of CVD and presence of CHF were associated with poor prognosis. END development was found to be associated with poor prognosis. In the high-risk group, 30.3% (n = 33) had END. Among those in the high-risk group according to the CHADS2 score, END development rate was found to be significantly higher than in the moderate risk group (p <0.05). There was a strong positive correlation between CHADS2 and NIHS scores. mRS score increased with increasing CHADS2 score and there was a strong correlation between them. Effect of stroke severity on prognosis was assessed and a positive correlation was found between NIHS score and mRS value. Discussion - Our study demonstrated the importance of CHADS2 score, haemostatic activation and echocardiographic findings to assess stroke severity and prognosis. Knowing factors which affect stroke severity and prognosis in patients with ischemic stroke may be directive to decide primary prevention and stroke management.

[Hyperuricemia in hypertension. Domestic experience based on the data of the Hungarian Hypertonia Register 2011., 2013., 2015. Part II.]

ALFÖLDI Sándor, PAKSY András, KÉKES Ede

[Asymptomatic hyperuricemia is frequent in hypertension and its prevalence is increasing. Authors studied the incidence of serum uric acid levels and its correlation with age, risk factors, anthropological, metabolic characteristics, blood pressure, blood pressure target, organ damage, age-related co-morbidity in 47,372 hypertensive patients (22,688 males, 24,694 women). In the second part of their analysis the prevalence of hyperuricemia was 13.8% in hypertensive men and 21.6% in women. The age, BMI, waist diameter, systolic and diastolic blood pressure and onset of hypertension, serum cholesterol, triglyceride, blood glucose and serum creatinine were slightly higher, but serum HDL cholesterol and eGFR were slightly lower in hyperuricemic hypertensive patients, independently of their gender. Among hypertension mediated organ damage ischemic and left ventricular hypertensive ECG alterations, mild chronic kidney disease and proteinuria, among hypertension associated diseases diabetes associated ischemic heart disease, chronic kidney disease associated diabetes and both ischemic and chronic kidney disease associated diabetes were significantly more frequent in hyperuricemic hypertensive patients.]

[Physical inactivity and activity. Damage and benefit]

KÉKES Ede, APOR Péter

[Authors address the issue of inadequate physical activity worldwide and analyze their relationship with cardiovascular diseases and total mortality. In the inactivity "world map" it can be seen that in economically developed countries it is very common but other ethnic and regional factors also play a role and it is significantly more frequent at women. In our country this phenomenon due to combination of advanced civilization and computerization is also frequent. From 2000 to 2015, the trend of the presence of physical inactivity (FI) in the high income populations is steadily rising. Convincing evidence suggests that FI increases the risk of many common, serious diseases, including ischaemic heart disease, type 2 diabetes, breast cancer and colon carcinoma, and reduces the life expectancy. For these four diaseses, the incidence of FI occurs in about 1/3 of cases and 35% of total mortality. Its health value (PAF) ranges from 10 to 18%. Low (non-regular) exercise increases the risk of hypertension with or without family history. In subjects with moderate and intensive levels of physical activity (FA), there is a significantly lower mortality rate and the rate of occurrence of major cardiovasculars (CV) diseases compared to those with lower grade FA. Behind the positive effect of physical activity there is a multiple and complicated mechanism that manifests itself in the vascular system, in the physiological adaptation of the heart and in other metabolic and cellular effects. ]
