Opis:
Background. Currently, there is little documented research evaluating the effect of a high-mountain environment on patients with ischemic heart disease. Objectives. The main aim of the study was to assess the effect of normobaric hypoxia on exercise tolerance in patients diagnosed with stable coronary disease. Material and methods. 22 men aged 37 to 72 (55.68 ± 9.86 years of age) with coronary disease were qualified. In the pre-study, in a normobaric normoxia environment, each patient underwent: resting ECG, spiroergometric test using a treadmill, laboratory tests (gasometry, lactic acid concentration). The patients stayed in the cabinet for 3 hours at the: 1) normoxia, 2) hypoxia (2000 m a.s.l), 3) hypoxia (3000 m a.s.l.) levels. After the 3-hour period, patients underwent a spiroergometric exercise tolerance test combined with a blood lactic acid concentration test. Venous blood and capillary blood were drawn for gasometry testing purposes. Results. Under 2000 and 3000 m hypoxia noted a significantly shorter duration of the exercise test, distance travelled and MET values. An increase in resting blood pH and a decrease of resting and peak pCO2 and pO2 were observed. Conclusions. As a result of a 3-hour exposure to normobaric hypoxia, the exercise tolerance of patients after acute coronary syndrome treated with angioplasty combined with coronary stent implantation decreases. There is no clear information for patients as to whether high mountain conditions are safe for them. The presented research was a form of introduction to wider and more thorough experiments that can result in practical information for patients.

Opis:
INTRODUCTION: : Coronary artery disease (CAD) leads to mortality and morbidity globally. Approximately, 18 million deaths occurred due to cardiovascular diseases. Objective: To determine the association between knowledge about coronary angiography and anxiety level among patients undergoing coronary angiography. MATERIAL AND METHODS: Analytical cross-sectional study was conducted in two major public-sector hospitals between September 2017 to March 2018. A total of 264 patients were recruited in the study Rusing a non-probability convenience sampling technique. A modified questionnaire about coronary angiography was distributed among participants and the HADS scale was used to assess the anxiety level of the participants. SPSS version 22 was used for data analysis. RESULTS: The mean knowledge score of the participants about angiography was 17.88 ± 4.047. The total knowledge score of both hospitals was good knowledge (6%), fair knowledge (42%) and had poor knowledge (52%). Regarding anxiety level, the participants of both hospitals experienced a high level of anxiety i.e. mild (20%), moderate (34%) & sever (10%). A significant association was found between knowledge and anxiety levels among the participants of both hospitals with a p-value of <0.001. CONCLUSIONS:This study found a significant association between patient’s knowledge about coronary angiography and anxiety level among patients undergoing coronary angiography. The study puts forwards that nurses shall assess the patient’s knowledge before coronary angiography procedure. The provision of accurate knowledge renders categorical purpose to this procedure for salubrious patients’ outcomes.

Smoking rates in coronary patients over the decade 1997–2007. Results of Cracovian Program for Secondary Prevention of Ischaemic Heart Disease and Polish parts of EUROASPIRE II and EUROASPIRE III surveysBackground: Smoking is one of the most important risk factors. Persisting smoking after an coronary event is related to significantly higher risk of the future cardiovascular complications. Studies performed in late nineties showed that a considerable percentage of patients continue with smoking after an coronary event. The aim of the present paper was to compare smoking rates in coronary patients in the post-discharge period in Krakow in 1997/1998, 1999/2000 and 2006/2007.Methods: Consecutive patients hospitalized from July 1, 1996 to September 31, 1997 (first survey), from March 1, 1998 to March 30, 1999 (second survey), and from April 1, 2005 to July 31, 2006 (third survey) due to acute myocardial infarction, unstable angina or for myocardial revascularization procedures, below the age of < 71 years were identified and then followed up, interviewed and examined 6–18 months after discharge. Self-reported smoking and breath carbon monoxide was analysed.Results: The number of patients who participated in the follow-up examinations were: 418 (78.0%) in the first survey, 427 (82.9%) in the second and 427 (79.1%) in the third survey. There was no significant change in smoking (self-reported) rates (16% vs 16% vs 19%; p = NS). When breath carbon monoxide was also analysed once again the difference did not reach significance (18% in 1999–2000 and 23% in 2006–2007; p = NS). Nicotine replacement therapy, bupropion or varenicline were also not used (0% vs 0.2% vs 0.5%; p = NS).Conclusion: The smoking rate in coronary patients over the decade from 1997/1998 to 2006/2007 did not changed significantly. The pharmacotherapy for smoking is almost not used in coronary patients.

Opis:
The present work is aimed at comparing the effectiveness of two different methods of risk factor assessment used for prediction of the CAD (coronary artery disease): the logistic regression method and the application of artificial neural networks. The former is widely used in medical research, while the latter is relatively rare. In the logistic regression method hierarchical analysis was employed to select the significant variables of the classification process. In the neural network approach several strategies were proposed for selection of the discriminative variables, all based on weight analysis in the constructed networks. Both methods have produced a consistent set of discriminative variables (Glu0, Ins0, Ins30, BMI, apoA1 and HDL-Ch), belonging to three groups of risk factors associated with insulin resistance, obesity and lipid disorders.

Opis:
Introduction. The technology of laser atherectomy has been known for about 20 years. Initial studies were not encouraging due to similar or lower efficacy compared to conventional angioplasty and greater complication rate. The introduction of new, low-profile catheters with high parameters of transmitted energy, a change in the procedure for performing angioplasty and the proper qualification of the lesions resulted in a reduction of adverse effects. Objective. The aim of the study was to present the current state of knowledge regarding the usage of excimer laser in coronary and peripheral arteries stenosis, its indications and contraindications as well as safety aspect. The article reviews 32 recent publications available on the PubMed and Google Scholar databases. Abbreviated description of the state of knowledge. The excimer laser emits ultraviolet energy and ablates the tissue in a vessel. The main indications for the use of the laser include: restenosis in the stent, ostial lesions, long, calcified lesions >20 mm and moderately and severely calcified lesions. There are isolated reports describing the use of ELCA in the treatment of acute coronary syndromes. Excimer laser also can be applied in a treatment of stenosis of peripheral arteries. Conclusion. Excimer laser coronary atherectomy is a safe and feasible technique for the treatment of ISR and is associated with a relatively low recurrent restenosis compared to scoring balloon dilatation alone. It is a very important and safe alternative to classic treatment methods, but further research assessing the usefulness of this procedure is required.

Opis:
Classification and regression trees are very popular and attractive types of classifiers, widely used to solve decision-making problems in different fields of science. The study was conducted to identify preoperative risk factors associated with morbidity outcome among patients undergoing isolated Coronary Artery Bypass Grafting (CABG) and to develop some classification rules assigning patients to selected risk subgroups. Prediction rules were established on the basis of the selected tree-structured models. The following tree-based algorithms were used: QUEST, CRUISE, LOTUS and PLUS.
Drzewa klasyfikacyjne i regresyjne należą do bardzo popularnych metod klasyfikacji, przede wszystkim ze względu na prostotę interpretacji i przejrzystą formę wizualizacji wyników. Stąd też są one szeroko wykorzystywane do rozwiązywania problemów decyzyjnych w różnych dziedzinach nauki. Celem prowadzonych badań była identyfikacja przedoperacyjnych czynników ryzyka, związanych z wystąpieniem powikłań śród- i pooperacyjnych wśród pacjentów z chorobą wieńcową, leczonych w sposób operacyjny. Dodatkowo podjęto próbę zdefiniowania reguł decyzyjnych, które mogłyby umożliwić przydzielenie pacjenta do jednej z wyróżnionych grup ryzyka operacyjnego na podstawie opisujących go cech przedoperacyjnych. Reguły klasyfikacyjne budowano wykorzystując metodę rekurencyjnego podziału. W analizie uwzględniono algorytmy QUEST i CRUJSE, tworzące drzewa klasyfikacyjne oraz algorytmy LOTUS i PLUS, łączące rekurencyjny podział przestrzeni cech z analizą regresji logistycznej.

Opis:
Aim. The primary concern of the study was to compare pro-health behaviors in participants with stable coronary artery disease (SCAD), also known as stable ischemic heart disease (SIHD), and in healthy controls in order to improve the effectiveness of preventive measures in that group of patients. Material & methods. The study comprised a total of 394 participants aged 18 to 88 years (mean age 49.5±14.9 yrs), including 294 patients of the Cardiology Outpatient Clinic who were treated due to SCAD and 100 healthy controls. All participants were asked to complete the Health Behavior Inventory (HBI) by Juczyński. Moreover, the measurements of their body weight, height and waist and hip circumference were taken, and their BMI and WHR values were calculated. Finally, the risk for developing metabolic complications was assessed. Results. Healthy body weight was discovered in 32.6% (n=96) of cardiology patients and in 45.0% of controls. Abdominal obesity was more often found in cardiology patients (55.0%) than in controls (49.0%). Increased risk for obesity complications was disclosed in 60.2% of SCAD patients and in 37.0% of controls. Cardiology patients maintained health-related attitudes to a greater extent than controls on each subscale (p<0.05). Conclusions. Secondary prevention of coronary artery disease (CAD) should include both maximization of effective treatments and constant support of and encouragement for patients to reduce CAD risk factors and develop and implement pro-health behaviors.
Cel badań. Celem pracy było porównanie zachowań zdrowotnych pacjentów ze stabilną chorobą wieńcową oraz osób zdrowych, co pozwoli na optymalizację działań profilaktycznych na rzecz pacjentów. Materiał i metody. Badaniami objęto 394 osoby w wieku od 18 do 88 lat (49,5±14,9 lat), w tym 294 pacjentów Poradni Kardiologicznej, leczących się z powodu stabilnej choroby wieńcowej i 100 osób zdrowych. Posłużono się Inwentarzem Zachowań Zdrowotnych Juczyńskiego. Przeprowadzono pomiar masy, wysokości ciała, obwodu talii i bioder, obliczono wskaźnik BMI oraz WHR. Oszacowano ryzyko powikłań metabolicznych. Wyniki. Prawidłową masę ciała miało 32,6% (n=96) pacjentów kardiologicznych i 45,0% osób z grupy kontrolnej. Nadmierne gromadzenie tkanki tłuszczowej w okolicy brzucha obserwowano częściej u pacjentów kardiologicznych (55,0%) niż u osób zdrowych (49,0%). Podwyższone ryzyko powikłań otyłości obserwowano u 60,2% pacjentów z CAD i 37,0% osób zdrowych. Pacjenci z CAD w większym stopniu cechowali się pozytywnymi zachowaniami zdrowotnymi w każdej podskali,w porównaniu z osobami zdrowymi (p<0,05). Wnioski. W ramach prewencji wtórnej choroby wieńcowej istotna jest zarówno maksymalizacja efektywnego leczenia, jak i zakrojona na szeroką skalę promocja zwalczania czynników ryzyka i przyjęcia pozytywnych zachowań zdrowotnych.

Aim: The aim of this study is to examine uric asid (UA) and high sensitive C-Reactive protein (Hs-CRP) levels in patients with coronary artery ectasia (CAE). Materials and Methods: Ninety-eight patients with isolated CAE (mean age 57.5±10.3), (group-I), 110 patients with CAD but without CAE (mean age 56.3±10.7), (group-II), and 105 patients with normal coronary angiographies (mean age 58.1±10.8), (group-III) were included in the study. Blood samples of all individual were taken after coronary angiography from an antecubital vein, the patients uric acid and Hs-CRP levels were assessed. The severity of ectasia was evaluated and categorized according to Markis. Results: A significant difference was not seen in serum uric acid and Hs-CRP levels between CAE and CAD groups. However, relative to the control group, uric acid and Hs-CRP levels in CAE and CAD groups were higher to a significant degree (p=0.001, p<0.001, respectively), (p<0.001, p<0.001, respectively). The statistical significant was detected between subgroups type I and type IV, Hs-CRP and UA were statistically high in subgroup type I. (p=0.012, p=0.033, respectively) In multiple regression analysis, CAE and CAD were independently associated with UA (β=0.76; p<0.001, β=0.68; p<0.001, respectively) and Hs-CRP (β=0.66; p<0.01, β=0.62; p<0.01, respectively) along with diabetes mellitus (β=0.61; p=0.039, β=0.94; p=0.028, respectively). Conclusion: In conclusion, the blood uric acid and Hs-CRP values in our study have been observed to be higher in the individuals with coronary arteri ectasia in comparison to normal individuals, and the increase in these values were found to be parallel to the extent of the ectasia.

Objectives Legislators and policymakers have expressed strong interest in intervention programs to reduce dependence on social disability benefits. Hybrid: ambulatory followed by home-based cardiac telerehabilitation – hybrid cardiac rehabilitation (HCR) seems to be a novel alternative for standard cardiac rehabilitation for patients with cardiovascular diseases (CVD) as a form of pension prevention paid by the Social Insurance Institution (SII). The kind of professional status may bias the motivation to return to work after HCR. The aim of our study was to evaluate whether the professional status can affect the effects of HCR. Material and Methods One hundred fifty-two patients with CVD referred by the SII for a 5-week HCR were qualified for the study. Patients (87.7% males), aged 57.31±5.61 years, were divided into 2 subgroups: W) white-collar employees (N = 22) and B) blue-collar employees (N = 130). To evaluate functional capacity, an exercise test on a treadmill was used. Results The number of days of absence in the cardiac rehabilitation program did not differ between the groups (mean ± standard deviation – B: 1.09±3.10 days, W: 1.95±3.64 days). There were significant improvements (p < 0.05) in measured variables after HCR in both (W and B) groups (max workload: 8.21±2.88 METs (measured in metabolic equivalents) vs. 9.6±2.49 METs, 7.76±2.51 METs vs. 8.73±2.7 METs, resting heart rate (RHR): 77±16.22 bpm vs. 69.94±12.93 bpm, 79.59±14 bpm vs. 75.24±11.87 bpm; double product, i.e., product of heart rate and systolic BP (DP rest) 10 815.22±2968.24 vs. 9242.94±1923.08, 10 927.62±2508.47 vs. 9929.7±2304.94). In group B, a decrease in systolic blood pressure (BP syst. – 137.03±17.14 mm Hg vs. 131.82±21.13 mm Hg), heart rate recovery in the 1st minute after the end of peak exercise (HRR1) (99.38±19.25 vs. 93.9±19.48) and New York Heart Association (NYHA) class (1.22±0.53 vs. 1.11±0.36) was observed. In group W, a decrease in diastolic blood pressure (BP diast.) at rest was observed (88.28±9.79 mm Hg vs. 83.39±8.95 mm Hg). The decrease in resting HR was significantly greater in group W (69.94±12.93 vs. 75.24±11.87, p = 0.034). Conclusions Hybrid cardiac rehabilitation is feasible and safe with high adherence to the program regardless of the patient’s professional status. Professional status did not influence the beneficial effect of HCR on exercise tolerance.

Opis:
Cardiovascular mortality remains a leading health and social problem in many countries throughout the world. Its main cause is related to atherosclerosis of coronary and cerebral vessels with their most severe consequences: heart attack and stroke. Therefore, it is obvious that current preventive measures include early detection of atherosclerosis process. Multi-detector computed tomography (MDCT) is one of imaging modalities allowing for noninvasive detection of atherosclerotic lesion within coronary arteries in subjects with accumulation of risk factors (smoking, high lipids, hypertension, male gender, family history) or with suspicion of coronary artery disease (CAD). In is very important that the tomographic images are taken in synchronization with cardiac cycle so that, during few heartbeats, an appropriate series of images can be recorded. Commonly, cardiac MDCT is used for visualization of cardiac and vessels morphology. Heart function can also be determined, however, this MDCT potential is only rarely applied, as current echocardiographic modalities are sufficient. Functional analysis of coronary arteries (flow, reserve) is usually approached by means of invasive procedures. We aimed at finding solution for evaluation of another kind of functional analysis of coronary arteries, namely vessel's wall compliance by means of MDCT coronary angiography. Under the proposed procedure, on basis of serial CT images of the vessels over entire cardiac cycles, the internal area of the blood vessel is measured and its changes during various phases of heartbeat (systole, diastole) are calculated. If the vessel wall has been changed by atherosclerotic plaque, either calcified or non-calcified, then its compliance will be reduced due to its stiffness. Calculation of coronary artery compliance requires a series of measurements, which is unreliable and impractical for doing manually. One component of the method described herein involves the images being converted into binary representations and the Hough Transform then applied. The overall methodology proposed in this paper assists in the preparation of a medical diagnosis.

Opis:
The aim of the present study was to systematically review the association of comorbid mental disorders with indirect health care costs in patients with coronary artery disease (CAD). A comprehensive database search was conducted for studies investigating persons with CAD and comorbid mental disorders (Medline, EMBASE, PsycINFO, Psyndex, EconLit, IBSS). All studies were included, which allowed for a comparison of indirect health care costs between CAD patients with comorbid mental disorders and CAD patients without mental disorders. The literature search revealed 4962 potentially relevant studies, out of which 13 primary studies met the inclusion criteria. Depression was investigated most often (N = 10), followed by anxiety disorders (N = 3) and any mental disorder not further specifi ed (N = 3). All studies focused on return to work as indirect cost outcome. CAD patients with depression showed diminished odds for return to work, compared to CAD patients without depression (OR = 0.37; 95% CI: 0.27-0.51). The fi ndings for comorbid anxiety and any mental disorder were inconsistent. Indirect health care costs were exclusively assessed by a patient self-report (N = 13). There is strong evidence for diminished odds of return to work in CAD patients with comorbid depression, highlighting the need for integrated CAD and depression care. With regard to other comorbid mental disorders, however, the evidence is sparse and inconclusive.

Opis:
Angiotensin I-converting enzyme (ACE), which plays an important role in blood pressure regulation, and methylenetetrahydrofolate reductase (MTHFR) involved in homocysteine metabolism belong to a large group of polypeptides which may be potential risk factors for atherosclerosis and coronary artery disease (CAD). To assess whether polymorphisms of the genes encoding these peptides are associated with CAD in Silesian we conducted a study among 68 individuals suffering from CAD (including 52 cases after myocardial infarction), 51 subjects with positive family history of CAD and 111 controls. We analysed the distribution of genotypes and allele frequencies of the insertion/deletion (I/D) polymorphism in the ACE gene using PCR amplification, and the C677→T polymorphism in the MTHFR gene using PCR-RFLP analysis. We found that D allele frequency was significantly higher in CAD patients (61%) than in controls (43%) (P = 0.001, OR = 2.06). The D allele carriers (DD + ID genotypes) were more frequent in the CAD patients (85%) compared to control group (65%) (P = 0.003, OR = 3.14), whereas the familial CAD risk group shows the highest frequency of the ID genotype (57% vs 43% in controls). In contrast, the MTHFR polymorphism does not seem to be associated with the disease. Our data indicate that in Silesian CAD patients the disease is strongly associated with carrier-state of the ACE D allele, but not with the C677→T transition in the MTHFR gene.
