Patients with atrial fibrillation and mid-range ejection fraction differ in anticoagulation pattern, thrombotic and mortality risk independently of CHA2DS2-VASC score.

Atrial fibrillation (AF) patients with mid-range left ventricular ejection fraction (mrEF) of 40-49% have neither preserved (pEF > 50%) nor reduced (rEF < 40%) EF and are increasingly being recognized as a distinct group with specific clinical risks. We aimed to retrospectively investigate clinical characteristics and associated thrombotic, bleeding and mortality risks of mrEF in comparison to pEF and rEF in a cohort of 1000 non-valvular AF patients presenting in our institution during the period 2013-2018. Patients with mrEF presented with older age (P < 0.001) and a higher frequency of arterial hypertension (P = 0.001) in comparison to both pEF and rEF patients. In comparison to pEF, mrEF patients were more likely to have diabetes mellitus (P = 0.004), lower HDL-cholesterol (P < 0.001) and lower estimated glomerular filtration rate (P < 0.001), significantly higher CHA2DS2-VASC score (P < 0.001), significantly higher HAS-BLED score (P = 0.002) and had a higher likelihood of receiving anticoagulant therapy, mostly warfarin (P = 0.001). In addition, mrEF patients had a significantly higher risk of thrombotic events (HR = 2.22; P = 0.015), death (HR = 1.71; P = 0.005) and composite endpoint of thrombosis, bleeding or death (HR = 1.65; P = 0.003) in comparison to pEF patients, but did not significantly differ in comparison to rEF patients. There was no significant difference regarding major bleeding risk. Associations with clinical outcomes remained statistically significant in multivariate models independently of CHA2DS2-VASC. Our findings support defining AF patients with mrEF as a subgroup with distinct clinical characteristics and increased risk for thrombotic events and death, irrespective of predetermined CHA2DS2-VASC risk. These patients seem to require special clinical considerations and more intensive control of cardiovascular risk factors.

Patterns of anticoagulation therapy in atrial fibrillation: results from a large real-life single-center registry.

AIM: To investigate the differences in the characteristics and clinical outcomes of recently diagnosed patients with atrial fibrillation (AF) receiving different types of anticoagulants in a real-life setting. METHODS: We retrospectively analyzed the charts of 1000 consecutive patients with non-valvular AF diagnosed at our institution or referred it to from 2013 to 2018. RESULTS: Over the observed period, the frequency of direct oral anticoagulation (DOAC) therapy use significantly increased (P = 0.002). Patients receiving warfarin had more unfavorable thromboembolic and bleeding risk factors than patients receiving DOAC. Predetermined stroke and major bleeding risks were similarly distributed among the dabigatran, rivaroxaban, and apixaban groups. Patients receiving warfarin had shorter time-to-major bleeding (TTB), time to thrombosis (TTT), and overall survival (OS) than patients receiving DOACs. After adjustment for factors unbalanced at baseline, the warfarin group showed significantly shorter OS (hazard ratio 2.27, 95% confidence interval 1.44-3.57, P<0.001], while TTB and TTT did not significantly differ between the groups. Only 37% of patients on warfarin had optimal dosing control, and they did not differ significantly in TTB, TTT, and OS from patients on DOACs. CONCLUSION: Warfarin and DOACs are administered to different target populations, possibly due to socio-economic reasons. Patients receiving warfarin rarely obtain optimal dosing control, and experience significantly shorter survival compared with patients receiving DOACs.

Mitochondrial unfolded protein response, mitophagy and other mitochondrial quality control mechanisms in heart disease and aged heart.

Mitochondria are involved in crucial homeostatic processes in the cell: the production of adenosine triphosphate and reactive oxygen species, and the release of pro-apoptotic molecules. Thus, cell survival depends on the maintenance of proper mitochondrial function by mitochondrial quality control. The most important mitochondrial quality control mechanisms are mitochondrial unfolded protein response, mitophagy, biogenesis, and fusion-fission dynamics. This review deals with mitochondrial quality control in heart diseases, especially myocardial infarction and heart failure. Some previous studies have demonstrated that the activation of mitochondrial quality control mechanisms may be beneficial for the heart, while others have shown that it may lead to heart damage. Our aim was to describe the mechanisms by which mitochondrial quality control contributes to heart protection or damage and to provide evidence that may resolve the seemingly contradictory results from the previous studies.

Primary Left Atrial Angiosarcoma Presenting as Acute Coronary Syndrome.

Primary cardiac neoplasms are extremely rare and often overlooked as differential diagnosis. Angiosarcomas are the most common primary malignant neoplasms of the heart often with nonspecific symptoms. We present a 43-year-old woman admitted to our hospital with chest pain and inferoposterolateral myocardial infarction. Coronary angiography indicated the distal occlusion of the left circumflex artery. Transthoracic and transoesophagic echocardiography revealed a mass in the left atrium with probable myocardial infiltration and vascularisation. The mass in the left atrium was removed by surgical resection, and histopathology confirmed angiosarcoma. We emphasize the pivotal role of transthoracic and transoesophageal echocardiography in evaluating even rare differential diagnosis of acute coronary syndrome as cardiac neoplasms.

Subadventitial stenting around occluded stents: A bailout technique to recanalize in-stent chronic total occlusions.

OBJECTIVES: To evaluate the outcomes of subadventitial stenting (SS) around occluded stents for recanalizing in-stent chronic total occlusions (IS-CTOs). BACKGROUND: There is little evidence on the outcomes of SS for IS-CTO. METHODS: We examined the outcomes of SS for IS-CTO PCI at 14 centers between July 2011 and June 2017, and compared them to historical controls recanalized using within-stent stenting (WSS). Target-vessel failure (TVF) on follow-up was the endpoint of this study, and was defined as a composite of cardiac death, target-vessel myocardial infarction, and target-vessel revascularization. RESULTS: During study period, 422 IS-CTO PCIs were performed, of which 32 (7.6%) were recanalized with SS, usually when conventional approaches failed. The most frequent CTO vessel was the right coronary artery (72%). Mean J-CTO score was 3.1 ± 0.9. SS was antegrade in 53%, and retrograde in 47%. Part of the occluded stent was crushed in 37%, while the whole stent was crushed in 63%. Intravascular imaging was used in 59%. One patient (3.1%) suffered tamponade. Angiographic follow-up was performed in 10/32 patients: stents were patent in six cases, one had mild neointimal hyperplasia, and three had severe restenosis at the SS site. Clinical follow-up was available for 29/32 patients for a mean of 388 ± 303 days. The 24-month incidence of TVF was 13.8%, which was similar to historical controls treated with WSS (19.5%, P = 0.49). CONCLUSIONS: SS is rarely performed, usually as last resort, to recanalize complex IS-CTOs. It is associated with favorable acute and mid-term outcomes, but given the small sample size of our study additional research is warranted.

Association between Circulatory and Plaque Resistin Levels with Carotid Plaque Instability and Ischemic Stroke Events.

ses of ischemic stroke. The risk of ischemic stroke increases with the degree of carotid stenosis and plaque vulnerability. The aim of this study was to investigate the association of circulating and plaque resistin levels with plaque vulnerability and ischemic stroke events in patients with moderate- to high-grade carotid artery stenosis. METHODS: 40 patients with ischemic stroke events and 38 neurologically asymptomatic patients scheduled for carotid endarterectomy were recruited for this study. Fasting blood samples for laboratory analysis were collected preoperatively and serum resistin levels were measured by enzyme-linked immunosorbent assays. Carotid endarterectomy specimens were analyzed according to the gold-standard procedure of histological classification. Plaque resistin expression was determined by standard immunohistochemical procedure. RESULTS: Serum resistin levels and resistin plaque expression were found to be significantly higher in subjects with unstable carotid plaque (P < .001) while significantly higher serum resistin levels were also present in patients with ischemic stroke events (P < .001). In univariate stepwise logistic regression analysis, higher serum resistin levels were significantly associated with plaque instability (OR 2.223, 95% CI 1.488-3.320, P < .0001) and ischemic stroke events (OR 1.237, 95% CI 1.079-1.420, P = .002). There was also a significant association between higher serum and plaque resistin expression (OR 1.663, 95% CI1.332-2.077, P < .0001). These associations remained significant in all models of multivariate logistic regression analysis. High serum and plaque resistin levels were also significantly associated with specific histological features of plaque instability. CONCLUSION: The results suggests that serum resistin levels may be used as a potential biomarker of plaque vulnerability and ischemic stroke events in patients with moderate- to high-grade carotid artery stenosis and highlight the possible relationship that plaque resistin expression has with histological features of plaque vulnerability.

Prognostic value of lactates in relation to gas analysis and acid-base status in patients with pulmonary embolism.

AIM: To assess the prognostic value of lactate level for mortality in patients with pulmonary embolism (PE) and Pulmonary Embolism Severity Index (PESI) I-III and its independence of gas-analysis parameters and acid-base status. METHODS: This prospective observational study was conducted at the University Clinical Hospital Mostar from 2013 to 2017. On the first day after PE diagnosis, 1.5 mL of arterial blood was collected from 103 patients with PE. Partial pressure of oxygen in arterial blood, partial pressure of carbon dioxide in arterial blood, blood pH value, concentration of bicarbonates in arterial blood (HCO3-), base deficit, and oxygen saturation were analyzed. Lactate levels were assessed using blood samples taken from the cubital vein. Logistic regression analysis was used to assess the predictive value of gas-analysis variables, lactate level, PESI score, age, and sex for in-hospital death due to PE. RESULTS: The mortality in the group of PE patients was 19.1% (18 of 103 patients). Lactate level was an independent predictor of mortality (P=0.002, odds ratio 0.06). HCO3- was also found to be a significant predictor (P=0.022, odds ratio 2.4). Lactates were independent of other variables. Other gas-analysis parameters were not significant predictors of mortality. CONCLUSION: In PE patients at low-intermediate risk of mortality (PESI I-III), lactate level was associated with a short-term mortality, independently of other gas-analytic parameters.

Arterial stiffness in patients with coronary artery disease: relation with in-stent restenosis following percutaneous coronary intervention.

BACKGROUND: Coronary artery disease (CAD) is one of the most important issues in modern medicine due to its high mortality and prevalence. An early detection and prevention can reduce morbidity and mortality. Arterial stiffness is a potent and independent predictor of CAD. We aimed to investigate the arterial stiffness in CAD patients undergoing the coronary angiography. Also, we investigated a possible correlation between arterial stiffness and in-stent restenosis (ISR), an important limitation of percutaneous coronary intervention (PCI). METHODS: The study included 160 patients undergoing coronary angiography, treated either with PCI or with CABG. The pulse wave velocity (PWV) and augmentation index (AIx) were measured by the Arteriograph. RESULTS: PWV in the CAD group (12.24 ± 2.78 m/s) was significantly higher compared to the control group (8.27 ± 1.89 m/s). PWV in ISR and left main (LM) stenosis group (14.03 ± 3.15 and 13.89 ± 2.95 m/s) was significantly higher compared to the control and CAD groups. Peripheral and central AIx were significantly higher in CAD group (1.38 ± 30.63 % and 38.35 ± 15.52 %) than in control group (-11.35 ± 26.74 % and 26.91 ± 10.62 %). Patients with LM stenosis have significantly higher values of peripheral and central AIx (23.37 ± 23.77 % and 49.71 ± 12.02 %) than the CAD and ISR group. CONCLUSIONS: The study confirmed a positive correlation between arterial stiffness measures, PWV and AIx, and CAD. Also, this study showed the correlation between PWV and ISR which can help to select more appropriate stent.

Prevention of contrast-induced nephropathy with Na/K citrate.

AIMS: Contrast-induced nephropathy (CIN) is a frequent complication of many radiological procedures involving the application of contrast media. It represents a significant health problem that causes the increase in mortality, morbidity, and medical costs. For the prevention of CIN, a number of methods have been proposed to be effective. Among them, alkalinization of urine takes an important place. Although the Na/K citrate is a well-known agent for urine alkalinization, it has not been studied in the prevention of CIN. METHODS AND RESULTS: Two hundred and two patients who underwent coronary angiography were included in the study. They were randomized into groups receiving the drug Na/K citrate per os and to the control group. Serum creatinine and glomerular filtration rate were determined in all patients immediately before coronary angiography, and 48 h after the procedure. CIN criteria were a creatinine increase of >25%, reduction in the glomerular filtration rate by >25%, or an increase in serum creatinine of >44 µmol/L. The incidence of CIN in the group receiving Na/K citrate was significantly lower when compared with the control group (4% compared with 20%, P = 0.0001). Patients who had a urine pH <6 had a more than ten-fold higher incidence of contrast nephropathy compared with patients whose urine pH was >6. CONCLUSION: Alkalinization of urine using the Na/K citrate may reduce the incidence of CIN.

Diagnostic value of MPO in patients admitted for suspected acute coronary syndrome--a study of adult in Mostar, Bosnia and Herzegovina.

We assessed the diagnostic efficacy of plasma Myeloperoxidasis (MPO) alone or in combination with cardiac troponin I (cTnI) for detecting ACS in patients presenting with chest pain initiating within 24 h before the hospital admission. In this prospective cohort study were included all respondents who have visited outpatient clinic of internal diseases, University Hospital Mostar because of chest pain and suspected acute coronary syndrome within 24 h of the onset of the period of 6 months and the total sample consisted of 114 patients. Troponin and myeloperoxidase were significantly positively correlated at the beginning of treatment, myeloperoxidase was significantly positively associated with adverse cardiovascular events during hospitalization and myocardial infarction (p < 0.05), with the regression analysis did not show a significant predictor in the development of myocardial infarction (p > 0.05). Sensitivity of myeloperoxidase as a valid test detection of myocardial infarction at baseline was 0.15 and specificity was 0.85, suggesting good diagnostic value usable in the clinical practice.

Red blood cell distribution width as a prognostic marker of mortality in patients on chronic dialysis: a single center, prospective longitudinal study.

AIM: To determine if red cell distribution width (RDW) is associated with all-cause mortality in patients on chronic dialysis and to evaluate its prognostic value among validated prognostic biomarkers. METHODS: This is a single center, prospective longitudinal study. At the time of inclusion in January 2011, all patients were physically examined and a routine blood analysis was performed. A sera sample was preserved for determination of NT-pro-brain natriuretic peptide (NT-pro-BNP) and eosinophil cationic protein. Carotid intima media thickness (IMT) was also measured. Following one year, all-cause mortality was evaluated. RESULTS: Of 100 patients, 25 patients died during the follow-up period of one-year. Patients who died had significantly higher median [range] RDW levels (16.7% [14.3-19.5] vs 15.5% [13.2-19.7], P<0.001. They had significantly higher Eastern Cooperative Oncology Group (ECOG) performance status (4 [2-4] vs 2 [1-4], Plt;0.001), increased intima-media thickness (IMT) (0.71 [0.47-1.25] vs 0.63 [0.31-1.55], P=0.011), increased NT-pro-BNP levels (8300 [1108-35000] vs 4837 [413-35000], P=0.043), and increased C-reactive protein (CRP) levels (11.6 [1.3-154.2] vs 4.9 [0.4-92.9], Plt;0.001). For each 1% point increase in RDW level as a continuous variable, one-year all cause mortality risk was increased by 54% in univariate Cox proportional hazard analysis. In the final model, when RDW was entered as a categorical variable, mortality risk was significantly increased (hazard ratio, 5.15, 95% confidence interval, 2.33 to 11.36) and patients with RDW levels above 15.75% had significantly shorter survival time (Log rank Plt;0.001) than others. CONCLUSIONS: RDW could be an additive predictor for all-cause mortality in patients on chronic dialysis. Furthermore, RDW combined with sound clinical judgment improves identification of patients who are at increased risk compared to RDW alone.

The H1N1 influenza pneumonia as early complication after heart transplantation--experience from the Dubrava University Hospital, Zagreb, Croatia.

In April 2009, a novel influenza A (H1N1) virus was initially detected, and only after two months World Health Organization declared pandemic, while virus became globally present. We report here a confirmed case of patient suffering from H1N1 influenza pneumonia in an early period after heart transplantation. Complications of influenza A and B include viral pneumonia, secondary bacterial pneumonia and possibly acute allograft rejection in the setting of weaning of immunosuppression. In our case H1N1 influenza pneumonia was treated according to the published guidelines and had a mild course of disease, but nevertheless emphasis should be put on the prevention of disease applying known general infection control procedures and vaccination while disease course cannot be predicted.

The prevalence of overweight and obesity among Croatian hospitalized coronary heart disease patients.

The aim of this article was to investigate the prevalence of overweight and obesity using selected anthropometric variables in a sample of hospitalized coronary heart disease (CHD) patients in Croatia (N = 1,298). Prevalence of overweight and obesity in surveyed patient population was high: 48.2% of participants were overweight and 28.6% were obese according to their body mass index; measured through waist-to-hip ratio 54.5% of participants were centrally obese. These data on prevalences of overweight, obesity and central obesity show that although there are some reassuring trends, there is still considerable amount of work to be done if the prevalence of this cardiovascular risk factor is to be reduced further among Croatian CHD patients. While the prevalence of obesity seems to be on the decline, the prevalence of overweight is rising, which may be just an early warning sign of an incoming wave of obesity epidemic in future years.

E2 allele of the apolipoprotein E gene polymorphism is predictive for obesity status in Roma minority population of Croatia.

BACKGROUND AND AIMS: The Roma (Gypsies) are a transnational minority, founder population characterized by unique genetic background modeled by culturally determined endogamy. The present study explores whether the widely found cardiovascular diseases (CVD) risk effects of ACE I/D, APOE (ε2, ε3, ε4), eNOS-VNTR and LEP G2548A polymorphisms can be replicated in this specific population. METHODS AND RESULTS: The community-based study was carried on 208 adult Bayash Roma living in rural settlements of eastern and northern Croatia. Risk effect of four CVD candidate polymorphisms are related to the most prominent classical CVD risk phenotypes: obesity indicators (body mass index and waist circumference), hypertension and hyperlipidemia (triglycerides, HDL and LDL cholesterol). For all of them the standard risk cut-offs were applied. The extent to which the phenotypic status is related to genotype was assessed by logistic regression analysis. The strongest associations were found for ε2 allele of the APOE as a predictor of waist circumference (OR 3.301; 95%CI 1.254-8.688; p = 0.016) as well as for BMI (OR 3.547; 95%CI 1.471-8.557; p = 0.005). It is notable that ε3 allele of APOE gene turned out to be a protective genetic factor determining low lipid levels. CONCLUSION: The strength of the relation and the similarity of the results obtained for both tested indicators of obesity provide firm evidence that APOE plays an important role in obesity development in the Roma population.

[Acute coronary syndrome: monitoring and invasive treatment]. / Akutni koronarni sindrom: monitoriranje i invazivno lijecenje.

Acute coronary syndromes whose clinical spectrum consists of unstable angina pectoris, non-ST-elevation myocardial infarction and ST-elevation myocardial infarction carry the greatest risk of death and severe complications to patients with coronary artery disease. Patients with acute coronary syndromes may be submitted to conservative or invasive management, with differences in the timing of invasive management in patients selected for that strategy. Early diagnosis, good monitoring and appropriate global assessment of every patient improve the selection of patients for adequate modality of treatment that will prevent death, complications and other serious events.

Patients with higher body mass index treated with direct / novel oral anticoagulants (DOAC / NOAC) for atrial fibrillation experience worse clinical outcomes.

INTRODUCTION: Due to fixed dosing of direct oral anticoagulants (DOACs), uncertainty exists about their efficacy in a population of obese/overweight patients. PATIENTS AND METHODS: We retrospectively investigated a real-life cohort of 325 DOAC anticoagulated patients with atrial fibrillation [179 receiving dabigatran (55%), 74 apixaban (23%) and 72 rivaroxaban (22%)]. Patients were stratified according to the body mass index (BMI) into non-obese (233 with BMI <30 kg/m2), class I obesity (71 with BMI 30-34.9 kg/m2) and class II + obesity (21 with BMI ≥35 kg/m2). RESULTS: Patients with higher BMI receiving DOACs were more likely to experience stroke/systemic embolism sooner (P = 0.043), experience major bleeding sooner (P < 0.001) and have shorter time to composite event consisting of thrombosis, bleeding or death (P < 0.001) whereas there was no significant association with overall survival (P = 0.470). BMI was significantly associated with thrombosis but not bleeding among dabigatran treated patients, and significantly associated with bleeding but not thrombosis among patients treated with factor Xa inhibitors. Associations of higher thrombotic, bleeding and composite endpoint risks with higher BMI remained statistically significant in multivariate Cox regression models adjusted for age, gender, eGFR, CHA2DS2VASC and HAS-BLED. CONCLUSION: Our findings indicate that obese patients receiving DOACs, especially ones with class II + obesity, might be under higher risks of stroke/bleeding depending on DOAC subtype. Loss of efficacy might be associated with dabigatran, whereas higher risk of major bleeding might be associated with factor Xa inhibitors.

[Varicella zoster myopericarditis in an immunocompetent adult]. / Mioperikarditis izazvan virusom varicella-zoster u imunokompetentnog odraslog bolesnika.

More than 20 viruses have been reported to cause myopericarditis, a rare but potentially dangerous complication. To our best knowledge only a few dozen cases of myopericarditis caused by varicella zoster virus have been reported, most frequently in children, seldom in immunocompetent adults. We report on a case of a myopericarditis caused by varicella zoster virus in a previously healthy young man, with a typical development and a fast and complete recovery. A 27-years-old male was admitted to our hospital with chest pain and signs of acute cardiac injury. He had no medical history of serious previous illnesses. Four weeks earlier, the patient was in contact with a child having chickenpox. Two days prior to admission patient became suddenly febrile up to 40 degrees C along with dry cough, and the following day intense chest pain set in. At the admission we found in the patient diffuse vesiculous exanthema on the whole body and capillitium. Heart beat was rhythmical with no audible murmurs or pericardial friction rub, 100 beats per minute, blood pressure RR 130/90 mm Hg, body temperature 37.4 degrees C, and ST segment elevation in lateral leads along with elevated cardiac markers were found. All parameters of complete blood count were within normal range. Chest X-ray showed somewhat enlarged heart with incipient signs of cardiac decompensation. Echocardiogram was normal, apart from a mild dyskinesis of the apical third of intraventricular septum, with ejection fraction slightly reduced to 50% and no valvular defect. Clinical diagnosis of acute infection with varicella zoster virus was confirmed serologically by a positive ELISA test. Patient received conservative therapy (isosorbide mononitrate, low molecular weight heparin, acetylsalicylic acid and bisoprolol), while he remained hemodinamically, and apart from one non sustained ventricular tachycardia immediately after admission, also rhythmically stable. During his stay in hospital we observed the typical evolution and regression of rash while the levels of cardiac markers normalised, with patient becoming afebrile the third day. Before dismission a control echocardiograph showed improvement of contractile function, ejection fraction improved to 65%, but also signs of mild pericarditis were recorded. Since the patient had no discomfort and was in a very good shape, he was dismissed from hospital with ibuprofen 400 mg twice a day as therapy. Two months later, the patient was readmitted for control. In the mean time he had no discomfort, all laboratory and the physical examination findings were normal, as well as the ECG. Echocardiogram showed normal contractility, systolic and diastolic function. Cardiac stress testing and coronary angiography both ruled out a coronary heart disease. Diagnosis of myocarditis in this case was made based on echocardiogram, anamnestic data and on the typical clinical presentation of an acute varicella zoster virus infection, and was serologically confirmed by ELISA test. Therapy with NSAID was started immediately and because of favorable development of the disease we did not perform myocardial biopsy. During second hospitalization an eventual coronary heart disease was ruled out by coronary angiography. Due to its rarity there are no guidelines regarding therapy of varicella myocarditis, but there is a consensus that these patients should receive intensive care unit. The basis of the therapy are certainly the NSAIDs, but also a combination of acyclovir and hyperimmunoglobulins has been reported which in this mild case was not necessary. With this report we want to point out that varicella zoster virus can cause myopericarditis in immunocompetent adults, which must be taken into consideration in differential diagnosis, and that an early diagnosis and adequate therapy can help achieve a fast and complete recovery.

[Invasive approach to patients with acute coronary syndrome]. / Invazivni pristup bolesniku s akutnim koronarnim sindromom--perkutane koronarne intervencije.

Cardiovascular diseases are the leading cause of mortality in Croatia. In concordance with this epidemiologic situation, a new organization of emergency medicine and a network of invasive cardiac laboratories have been introduced throughout Croatia. Main goal of this structuring is to improve the care of patients with acute coronary syndrome (ACS). The aim of this paper is to open discussion on the optimal way of treatment in patients with ACS in our country today, in the era of interventional cardiology of the 21st century. The pathophysiology of ACS encompasses a complex atheroinflammatory and atherothrombotic process with dynamic and progressive mechanical obstruction of coronary arteries and subsequently oxygen supply-demand mismatch. Conversely, the best way to treat such patients is reperfusion therapy, a goal nowadays achieved by either antithrombotic medical therapy or percutaneous coronary intervention (PCI). The weight of evidence does support the use of primary PCI as a standard and supreme reperfusion therapy, especially in myocardial infarction with ST elevation. The logistic complexities such as triage, transportation, the development of capable interventional center working 24-hours, even in developed countries, may be a major problem to use such a practice in the whole community. In ACS with non ST elevation, problems are even broader and include the importance of using optimal revascularization procedure (even cardiac surgery), timing and concomitant medical therapy, with certain stratification of every individual. Finally, especially for our country, medical and economic resources should be used optimally in order to achieve an optimal system to treat patients with ACS.

Traditional CVD risk factors and socio-economic deprivation in Roma minority population of Croatia.

Researches into health inequalities consistently show disadvantages in health status, morbidity and mortality for various ethnic minority groups. Current knowledge about prevention of cardiovascular diseases (CVD) mainly derives from studies carried out in populations of European origin while the evidences involving Roma population are scarce. Roma, an ethnic minority of northern Indian origin, live in many countries throughout the world and are well known for preserved traditions and resistance to assimilation. They are most often marginalized economically, spatially, politically and in terms of culture. In order to assess the health status and health-related lifestyle attributes, a multidisciplinary anthropological and epidemiological community-based study was carried out including a total of 423 members of the Bayash Roma minority population living in two regions of Croatia (144 men and 279 women, aged 18-84 yrs). Hypertension (HT) was found in 24.8% Bayash Roma (21.5% men and 26.5% women) using standard diagnostic criteria (i.e. BP > or = 140/90 mm Hg or taking antihypertensive therapy). The prevalence increases from 5.9% in the age group 18-34 yrs; 35.0% in the age group 35-64 yrs, and 51.4% in the age group 65+ yrs. The prevalence of hypertension in the Bayash Roma is almost half of the magnitude of what is usually reported for the general population of Croatia. It is also lower when compared with other European populations and this finding is not due to comparatively younger average age of the Bayash sample. The significant association of hypertension with age and BMI was confirmed in this study and the importance of non-traditional SES-related CVD risk factors was highlighted. Smoking is a part of traditional Roma life-style and with 70% of smokers almost the entire population is equally exposed to this risk factor in their family environment. Since homogenously distributed, this risk factor did not show to be a significant predictor of hypertension. The extent to which hypertension is influenced by traditional CVD risk factors as well as by some SES indicators was also assessed using a forward stepwise method of the multivariate logistic analysis. Each risk factor was explored as quantitative variable as well as qualitative one using various cut-offs. The best model showed to be the one having age and BMI presented as quantitative variables and sex, region, smoking status, income and schooling years as categorical ones; with cut-off 3 for number of income sources and 8 for the number of schooling years. In spite of the low prevalence of hypertension, the presented results are showing that Bayash Roma are bearing a high CVD risk factors load. We expect that with westernization of their life-style and along with increase of the economic power, the proportion of CVD in population of Bayash Roma will also increase. Therefore, it is important to recognize the need for early cardiovascular disease risk factors prevention in this minority population.

Suggesting a New Primary Access Site for Treating Chronic Total Occlusions: Bilateral Distal Transradial Intervention (bdTRI).

Bilateral distal transradial intervention is a new primary access strategy for chronic total occlusion interventions. We provide a brief review of recent studies and offer the rationale behind this promising approach.
