Ocena skuteczności leczenia hipotensyjnego pacjentów z nadciśnieniem tętniczym i chorobą niedokrwienną serca lub ekwiwalentem wieńcowym

Introduction. Arterial hypertension (AH) is a well-known cardiovascular risk factor. Currently, in Poland, approximately 32% of adults suffer from AH, and only 26% of them are treated successfully. The study aims to determine the incidence of atherosclerosis risk factors and their influence on the effectiveness of hypotensive treatment in the population of patients with AH and coexisting coronary artery disease (CAD) or coronary equivalent. Material and methods. The study included 204 adults. The inclusion criteria were: diagnosis of AH with coexisting a diagnosis of CAD (138 people) or coronary equivalent defined as high (≥ 5%) atherosclerosis-related risk of death in 10-year prognosis, estimated using the EURO SCORE scale (66 people). During observation, pharmacological and nonpharmacological treatments were modified according to the current AH treating standards. After 6 months of observation, the effectiveness of AH control was assessed. Results. Multivariate logistic regression analysis revealed that main factors affecting poor blood pressure control after six months of observation were: obesity, age > 65 years, LDL cholesterol level > 130 mg/dL. Moreover, systolic blood pressure (SBP) < 140 mmHg was more frequent in patients with diabetes mellitus. After six months of therapy, good control of SBP was found in 42.7% of patients and normal values of diastolic blood pressure (DBP) — in 65.2 % of patients. Conclusion. Independent risk factors for poor control of blood pressure were: high level of LDL-cholesterol, age > 65 years and female sex. Paradoxically, diabetes was not a risk factor for poor control of hypertension. The introduction of combined hypotensive and lipid-lowering drugs should contribute to a better control of hypertension in Poland.Wstęp. Nadciśnienie tętnicze (AH) jest uznanym czynnikiem ryzyka schorzeń układu sercowo-naczyniowego. Obecnie 32% Polaków ma stwierdzone nadciśnienie tętnicze, z czego tylko 26% jest skutecznie leczonych. Celem pracy było określenie częstości występowania czynników ryzyka miażdżycy i ich wpływu na skuteczność leczenia hipotensyjnego w populacji pacjentów z AH i współistniejącą chorobą niedokrwienną serca (CAD) lub ekwiwalentem wieńcowym. Materiał i metody. Kryterium włączenia do badania dla 204 osób stanowiło rozpoznanie HA (204 osoby), rozpoznanie CAD (138 osób) lub obecność ekwiwalentu wieńcowego rozumianego jako wysokie (≥ 5%) ryzyko zgonu z powodu miażdżycy w ciągu najbliższych 10 lat, szacowane według skali oceny ryzyka SCORE (66 osób). W czasie obserwacji modyfikowano postępowanie niefarmakologiczne i farmakologiczne zgodnie z obowiązującymi standardami leczenia AH, ponownie oceniając uzyskaną skuteczność kontroli AH po 6 miesiącach. Wyniki. Analiza wieloczynnikowa wykazała, że niezależnymi czynnikami wpływającymi na brak prawidłowej kontroli wartości ciśnienia tętniczego po 6 miesiącach były: otyłość, wiek > 65 lat, stężenie cholesterolu frakcji LDL > 130 mg/dl. Wykazano również, że pacjenci z cukrzycą łatwiej osiągali wartości skurczowego ciśnienia tętniczego (SBP) < 140 mm Hg. Po 6 miesiącach terapii zadowalającą kontrolę SBP odnotowano u 42,7%, a rozkurczowego ciśnienia tętniczego u 65,2% pacjentów. Wnioski. Niezależnymi czynnikami ryzyka braku prawidłowej kontroli wartości ciśnienia tętniczego były: podwyższone stężenia cholesterolu frakcji LDL, otyłość, wiek > 65 lat i płeć żeńska. Paradoksalnie, cukrzyca nie była czynnikiem zwiększającym ryzyko nieprawidłowej kontroli wartości ciśnienia tętniczego. Wprowadzenie skojarzonych preparatów hipotensyjno-hipolipemizujących powinno w szczególny sposób przyczynić się do lepszej kontroli nadciśnienia tętniczego w Polsce

Prevalence of arterial hypertension in patients with atrial fibrillation undergoing ablation — a prospective, cohort study

Background Arterial hypertension is one of the major cofounders in the development of atrial fibrillation (AF) and hypertension is commonly found in AF patients. The aim of the study was to establish the prevalence of arterial hypertension in patients undergoing ablation, who are relatively young and healthy group of AF patients. Material and methods 266 consecutive patients admitted for AF ablation were screened for arterial hypertension. All patients had their blood pressure measured on admission by, prior to the ablation procedure by a qualified physician, according to the current guidelines. Also, medical records of patients were reviewed for the previous diagnosis of hypertension or taking hypotensive agents. Results The study group was predominantly male (65.0%; mean age 57.6 ± 10.1 years). Mean body mass index was 29.7 ± 5.0 kg/m2. Paroxysmal AF was present in 69.5% of patients. In 72.9% of patients hypertension was diagnosed previously. On admission, mean systolic and diastolic blood pressure values were 131.7 ± 16.7 and 80.7 ± 11.1 mm Hg. 123 (46.2%) patients had systolic and/or diastolic blood pressure values respectively > 140 and/or > 90 mm Hg. Patients with previously diagnosed hypertension were older (58.7 ± 8.7 vs 54.6 ± 12.7 years; p = 0.003), had higher BMI (30.3 ± 5.0 vs 28.1 ± 4.8 kg/m2; p = 0.002), and more often history of diabetes (10.8% vs 1.4%; p = 0.03) compared to non-hypertensive group. There were no differences in terms of history of dyslipidaemia, stroke, myocardial infarction or family history of cardiovascular disease. Conclusions In patients with AF undergoing ablation procedure, prevalence of diagnosed arterial hypertension is very high, much higher than in the general population. Nevertheless, majority of patients meet the criteria for adequate blood pressure control

Common mitochondrial polymorphisms as risk factor for endometrial cancer

Endometrial carcinoma is the most commonly diagnosed gynaecological cancer in developed countries. Although the molecular genetics of this disease has been in the focus of many research laboratories for the last 20 years, relevant prognostic and diagnostic markers are still missing. At the same time mitochondrial DNA mutations have been reported in many types of cancer during the last two decades. It is therefore very likely that the mitochondrial genotype is one of the cancer susceptibility factors. To investigate the presence of mtDNA somatic mutations and distribution of inherited polymorphisms in endometrial adenocarcinoma patients we analyzed the D-loop sequence of cancer samples and their corresponding normal tissues and moreover performed mitochondrial haplogroup analysis. We detected 2 somatic mutation and increased incidence of mtDNA polymorphisms, in particular 16223C (80% patients, p = 0.005), 16126C (23%, p = 0.025) and 207A (19%, p = 0.027). Subsequent statistical analysis revealed that endometrial carcinoma population haplogroup distribution differs from the Polish population and that haplogroup H (with its defining polymorphism - C7028T) is strongly underrepresented (p = 0.003), therefore might be a cancer-protective factor. Our report supports the notion that mtDNA polymorphisms establish a specific genetic background for endometrial adenocarcinoma development and that mtDNA analysis may result in the development of new molecular tool for cancer detection

Znaczenie polimorfizmu CYP1A1 i regulacji jego transkrypcji w podatności na raka jajnika i endometrium

Abstract Human cytochrome P450 1A1 is one of the most important enzymes participating in human carcinogenesis because it metabolites several procarcinogens to active carcinogenic metabolites. Additionally, enzymes of CYP450 family play an important role in estrogenes catabolization (17-β-estradiol and estron) to intermediate products (2-, 4-hydroxyestradiol and 2-, 4-hydroxyestrone) including CYP1A1 that catalyses hydroxylation to 2-hydroxyestrogens in the endometrium. Derivates of these compounds (4-hydroxyestrogens) are carcinogenic and could induce DNA damage leading to tumour transformation. The presence of CYP1A1 enzyme in genital tract tissues could induce chemical carcinogenesis initiating cancer development. Recent studies also confirmed the role of CYP1A1 in the development of ovarian and endometrial cancer in humans. The presence of mutated CYP1A1 polymorphic variants influencing the CYP1A1 activity could be responsible for different interindividual susceptibility to genital cancers in women.Streszczenie Ludzki cytochrom CYP4501A1 jest jednym z najważniejszych enzymów uczestniczących w procesie kancerogenezy, ponieważ metabolizuje wiele pro-kancerogenów do ich aktywnych kancerogennych metabolitów. Dodatkowo, enzymy z rodziny CYP450 odgrywają ważną rolę w katabolizmie estrogenów (17-β-estradiol i estron) do produktów pośrednich (2-, 4-hydroksyestradiol oraz 2-, 4-hydroksyestron) uwzględniając CYP1A1, który katalizuje hydroksylację do 2-hydroksyestrogenu w endometrium. Pochodne tych związków (4-hydroksyestrogeny) są kancerogenne i mogą indukować uszkodzenia DNA prowadząc do transformacji nowotworowej komórki. Obecność enzymu CYP1A1 w tkankach narządów płciowych może indukować chemiczną kancerogenezę inicjując rozwój nowotworu. Najnowsze badania potwierdziły rolę CYP1A1 w rozwoju raka jajnika i endometrium. Obecność zmutowanych wariantów polimorficznych genu CYP1A1 wpływających na aktywność CYP1A1 może być związana ze zróżnicowaniem osobniczym w podatności na nowotwory narządów płciowych u kobiet

The relationship between the use of cement during total hip replacement and blood pressure values

Background Total hip replacement is a common orthopaedic procedure associated with an elevated cardiovascular risk. There are several methods for total hip replacement, including whether or not to use cement for the prosthesis fixation. The aim of the study was to compare clinical characteristics, including blood pressure, in patients undergoing total hip replacement with and without the use of cement. Material and methods The study included patients with elective total hip replacement surgery, who were divided into those in whom the procedure was performed with or without the use of medical cement. The criteria for using cement were assessed during operation by the operator, according to the current protocol. All patients were interviewed, screened, and had their medical records checked for the prior diagnosis of cardiovascular risk factors. Blood pressure values were measured before and after the procedure according to the current guidelines. Results The study population consisted of 65 patients in whom the total hip replacement was performed (mean age 61.5 ± 15.0 years; 50.8% male). 60% of patients had the hip replacement without cement and 40.0% had a procedure with the use of cement. Patients in whom the cement was used were significantly older (75.0 ± 8.5 vs. 53.0 ± 11.5 years; p < 0.0001) and more often diagnosed with arterial hypertension (61.5 vs. 33.3%; p = 0.04), than those in whom it was not used. Systolic blood pressure values were significantly higher before and after the procedure (138.8 ± 18.2 vs. 130.8 ± 21.5 mm Hg, p = 0.04; 122.6 ± 13.3 vs. 113.8 ± 14.1 mm Hg, p = 0.03; respectively) in the group which required cement. Conclusions Patients with hip replacement using cement have higher systolic values before, and after the surgery than in patients in whom cement wasn’t used. Therefore careful management and risk assessment is especially important in patients receiving the total hip replacement with the use of cement.Background Total hip replacement is a common orthopaedic procedure associated with an elevated cardiovascular risk.

Czy możliwe jest wybranie „najlepszego” hipotensyjnego połączenia lekowego?

  Currently, approximately one third of adult Poles suffers from hypertension (HT). Most of current hy­potensive drugs in monotherapy lowers blood pres­sure values of less than 20/10 mm Hg. In most of the patients, this reduction is not sufficient. That is way, more and more is said about the use of hypotensive drugs consisting of several components, because due to their complimentary actions, the effectiveness of antihypertensive treatment is increased and better doctor-patient collaboration and treatment adherence is assured. The article presents clinical aspects of the use of telmisartan (“the best” angiotensin receptor blocker) with amlodipine, widely used calcium chan­nel antagonist.Około 1/3 dorosłych Polaków choruje na nadciśnienie tętnicze (HT). Większość współczesnych leków hipotensyjnych stosowanych pojedynczo wykazuje efekt hipotensyjny związany z redukcją wartości ciśnienia tętniczego w zakresie znacznie mniejszym niż 20/10 mmHg. U wielu pacjentów nie jest to redukcja wystarczająca. Dlatego też, coraz więcej mówi się o stosowaniu preparatów wieloskładnikowych, które dzięki wzajemnie uzupełniającemu się działaniu zawartych w nich substancji oraz pozytywnym wpływie na współpracę na linii lekarz — pacjent zwiększają skuteczność leczenia hipotensyjnego. W artykule przedstawiono kliniczne aspekty stosowania preparatu złożonego z telmisartanu, można powiedzieć „najlepszego” z sartanów, z amlodipiną, powszechnie stosowanym antagonistą wapnia

Association between vitamin D levels and arterial hypertension in women at very high cardiovascular risk

Background Vitamin D is a compound of great importance in controlling the biological functions of the body in a variety of ways. Significance of vitamin D in the pathogenesis and treatment of various diseases has been described repeatedly. One of the most discussed issues in the literature is the importance of vitamin D deficiency in the pathogenesis of hypertension. This relationship is particularly important in patients burdened with elevated cardiovascular risk, which undoubtedly represent patients with diagnosed disease of the cardiovascular system. The aim of the study was to determine the association between the occurrence of vitamin D deficiency and the prevalence of hypertension in premenopausal women at very high cardiovascular risk. Materials and methods The study included 49 women who had previously been diagnosed with cardiovascular disease. In all patients enrolled in the study serum concentrations of vitamin D were measured and the patients were classified to have vitamin D deficiency or normal vitamin D level, based on the existing criteria. The patients were also tested for the occurrence of hypertension. Medical records of all patients were reviewed for early diagnosis of hypertension, and blood pressure measurements were performed on admission to the hospital before the surgery by a qualified physician, in a manner consistent with current guidelines Results The study population was aged 47.7 ± 13.4 years. The mean body mass index was 25.2 kg/m2. Vitamin D deficiency was diagnosed in 25 (51%) patients, and hypertension was diagnosed in 30 women (61.2%). In patients with vitamin D deficiency hypertension occurred in 18 (72%) women, while in the group without vitamin D deficiency hypertension was diagnosed in 50% of cases (12 women). The observed difference between the groups was statistically significant (p = 0.049). There was no difference in the incidence of other cardiovascular risk factors between the groups, including the prevalence of dyslipidaemia or nicotine addiction. Conclusion Association of hypertension with the vitamin D deficiency has been repeatedly underlined in many scientific studies. In the present group of patients at very high cardiovascular risk, we confirmed the relationship of vitamin D deficiency with the occurrence of hypertension. Exact confirmation of this issue requires further, largescale research, but this study may suggest the importance of vitamin D supplementation in these patients.Background Vitamin D is a compound of great importance in controlling the biological functions of the body in a variety of ways.

Epidemiology of arterial hypertension in patients scheduled for elective hip replacement

Background: Assessment of blood pressure values and early diagnosis of hypertension are especially important in high-risk group, including patients in preoperative and postoperative period. The aim of the current study was the assessment of blood pressure values and prevalence of hypertension in patients undergoing elective hip replacement surgery — an orthopedic procedure associated with one of the highest cardiovascular complication rate. Material and methods: Two hundred and eighty-four consecutive patients admitted for elective hip replacement surgery were screened for arterial hypertension. All patients had their medical records reviewed for prior diagnosis and had their blood pressure measured on admission by a qualified physician prior to the procedure, according to the current guidelines. Results: The mean age of the study population was 62.2 ± 13.9 years and 42.7% of the patients were male. The body mass index (BMI) in the study population was 27.0 ± 4.2 kg/m2. Fifty-eight point two percent of patients were diagnosed with arterial hypertension previously. Mean blood pressure values on admission for systolic blood pressure (SBP) and diastolic blood pressure (DBP) were 134.5 ± 20.4 and 78.6 ± 13.1 mm Hg, respectively. In 43.2% of patients, the on admission blood pressure values exceeded the threshold of ≥ 140 and/or 90 mm Hg. Arterial hypertension was diagnosed de novo in 33 (15.0%) patients. Patients with the disease were older (67.5 ± 12.3 vs. 54.4 ± 13.9 years; p < 0.0001), and had higher BMI (27.6 ± 4.3 vs. 26.2 ± 3.8 kg/m2; p = 0.05) than patients without the diagnosed disease. Diabetes mellitus was more often found in hypertensive patients (13.3% vs. 3.3%; p = 0.02), they also more often had history of myocardial infarction (p = 0.02), stable coronary artery disease (p = 0.001) and heart failure (p = 0.006) compared to patients without the diagnosis. Conclusions: The majority of patients scheduled for elective hip replacement surgery is diagnosed with arterial hypertension. The disease is also diagnosed de novo in 15% of these patients. Screening for arterial hypertension is important in this group of patients and can potentially reduce the complication rates of the hip replacement surgery.Background: Assessment of blood pressure values and early diagnosis of hypertension are especially important in high-risk group, including patients in preoperative and postoperative period.
