RESUMEN
AIMS: The aim of this study is to analyse the prevalence, epidemiology, and anticoagulation prevention of stroke or transient ischaemic attack (TIA) in Czech patients with atrial fibrillation (AF). METHODS AND RESULTS: Retrospective observational analysis of diagnoses, procedures, and treatment reported to the Czech National Registry of Reimbursed Healthcare Services between 2015 and 2018. Prevalence of AF in 2018 was 4.3% of Czech population and the prevalence of stroke/TIA in AF patients was 22.3% with annual incidence of 181.62 cases per 100 000 inhabitants. In 2018, CHA2DS2-ASc score ≥4 was present in 98% AF patients in secondary and 59% in primary prevention, respectively, while the anticoagulation treatment was used by 71-81% of them. Between 2015 and 2018, the percentage of AF patients treated with warfarin monotherapy in primary prevention decreased from 35% to 31%, with acetylsalicylic acid (ASA) monotherapy from 18% to 16% and non-vitamin K antagonist oral anticoagulants (NOACs) monotherapy increased from 7% to 11%. In secondary prevention, the percentage of warfarin monotherapy treatment decreased from 35% to 32%, with ASA monotherapy from 20% to 18% and with NOACs monotherapy increased from 9% to 15%. CONCLUSION: This study followed all Czech patients with AF. The unadjusted prevalence and incidence of AF was higher compared with other countries and 2019 European Society of Cardiology Statistics. The study identified several gaps in standard of reimbursed care. 20-30% of AF patients with other risk factors were without any prevention medication and the share of ASA monotherapy in treated patients was 16-18%.

Thanks to developments in pharmacological and non-pharmacological treatment of heart failure over the last half century, there has been improved quality of life and reduced mortality and morbidity. Despite these advances, the prognosis of advanced heart failure remains poor and the number of patients with terminal heart failure is currently increasing. In the general medical community, knowledge of pharmacological and device therapy with implantable cardioverter-defibrillator or resynchronization therapy is prevalent. However, only a limited number of professionals, mostly in tertiary centres, have personal experience with the use of long-term mechanical circulatory support (MCS) in patients with advanced heart failure after the above conventional therapeutic options have been exhausted. The purpose of this communication is, therefore, to provide the general medical community with basic information about benefits, limitations and referral strategies for MCS.

AIM: Retrospective national sub-analysis of antidiabetic pharmacotherapy in patients with diabetes mellitus (DM) and heart failure (HF) based on data reported to the National Register of Paid Health Services in the Czech Republic between 2012-2018. METHODOLOGY AND RESULTS: In 2012, there were 75,022 patients with HF and DM (i.e. 42.5% of patients with HF), 6 years later 117,265 (i.e. 41.0% of HF patients in 2018). The most represented antidiabetic drug was metformin (45.6%). Of the insulins and analogues, glargine showed the largest positive trend (5.8% 2012; 14.8% 2018). Empagliflozin was the most prescribed SGLT-2 inhibitor (1.8% in 2018). A decrease in prescribing was observed for saxagliptin (0.5% 2012; 0.1% 2018) and for sulfonylurea derivates - gliclazide (13.0% 2012; 10.3% in 2018) and glimepiride (12.9% 2012; 9.0% 2018). Linagliptin was the most prescribed dipeptidyl peptidase inhibitor (0.7% 2012; 6.8% 2018). CONCLUSION: In the Czech Republic, between 2012 and 2008, there was an increase in prevalence of patients with heart failure and concomitant diabetes mellitus, their proportion being similar. In correspondence with other registries, metformin was used mostly. A positive trend was observed in prescription of DDP-4 and SGLT-2 inhibitors, while there was a significant decrease in patients taking sulfonylureas.

BACKGROUND AND AIMS: There are limited data on real clinical practice in heart failure patients in the Czech Republic. We analysed the clinical parameters from the Moravian Midlands Registry (MMR) and compared them to LCZ696 patients in the Paradigm-HF trial. The Moravian Midlands Registry is a retrospective patient database from two outpatient cardiology centres in the Czech Republic. The Paradigm-HF is a large-scale prospective randomized multicentre trial with more than 8000 individuals with stabilized chronic heart failure. METHODS: A retrospective analysis of heart failure with reduced ejection fraction patients from two outpatient cardiology centres in the Czech Republic from October 2016 to December 2019. RESULTS: Patients in the MMR were younger (60.5 ± 10.7 vs 63.8 ± 11.5 years, P<0.05), had a higher body mass index (30.3 ± 5.0 vs 28.1 ± 5.5, P<0.05) and higher serum creatinine level (101.9 ± 36.0 vs 99.9 ± 26.5 µmol/L, P<0.05). MMR patients had lower left ventricular ejection fraction (27.8 ± 6.9 vs 29.6 ± 6.1%, P<0.05). The serum N-terminal pro-B-type natriuretic peptide, [2563.5 (377-3536) vs 1631 (885-3154), was non significantly higher P=0.07]. Pharmacotherapy use differed for mineralocorticoid antagonist (91.4% in MMR vs 54.2% in Paradigm-HF), and digoxin (13.5% vs 29.2%). Beta-blocker use was similar (96.2% vs 93.1%) as was angiotensin-converting enzyme (ACE) inhibitors - (71.2% vs 78.0%) and angiotensin-receptor blockers - ARB (27.9% vs 22.2%). Dosages of the commonly used ACE inhibitors at the screening visit (Paradigm-HF) / before angiotensin receptor-neprilysin inhibitor administration (MMR) differed significantly only for ramipril (7.0 ± 3.1 mg vs 4.8 ± 2.9 mg, P<0.05), dosages of ARB were - losartan (67.1 ± 30.2 vs 39.6 ± 32.0 mg, P=0.09) and valsartan (181.5 ± 71.1 vs 130.9 ± 82.2 mg, P=0.07). There was a substantial difference in device-based therapy (ICD in 60.6%, CRT 25.9% in MMR vs 14.9% and 7.0% in Paradigm-HF). CONCLUSION: The differences between the groups for the majority of clinical parameters compared were minimal, except for younger age, higher body mass index and serum creatinine level and lower left ventricular ejection fraction and substantially lower dosage of administered ramipril prior to commencing sacubitril/valsartan therapy. There was a higher prevalence of implantable cardioverter-defibrillators (ICD) and cardiac resynchronization therapy (CRT) in the MMR group.
RESUMEN
BACKGROUND: Clinical parameters linked to a low benefit of ICD implantation and increased mortality risks are needed for an individualized assessment of potential benefits and risks of ICD implantation. METHODS: Analysis of a prospective registry of all patients hospitalized from 2009 to 2019 in a single centre for a first implantation of any type of ICD. RESULTS: A total of 2,681 patients were included in the registry. Until the end of follow-up (38.4 ± 29.1 months), 682 (25.4%) patients died. The one-year mortality in all patients, the one-year CV mortality, the three-year mortality in all patients, and the three-year CV mortality were 7.8%, 5.7%, 20.6%, and 14.8%, respectively. There was a statistically significant difference when the subgroups were compared according to the type of cardiomyopathy. No significant difference was found between primary and secondary prevention and between the types of devices. Male gender, age ≥ 75 years, diabetes mellitus, and atrial fibrillation were associated with a significantly increased mortality risk. CONCLUSION: In an analysis of a long-term follow-up of 2,681 ICD patients, we found no mortality difference between patients with ischemic or non-ischemic cardiomyopathy and in the device type. A higher mortality risk was found in men, patients older than 75 years, diabetics, and those with atrial fibrillation.

AIMS: Sub-analysis of a retrospective nation-wide observational analysis of heart failure (HF) epidemiology reported to the Czech National Registry of Reimbursed Health Services between 2012 and 2018 aimed at angiotensin-converting enzyme inhibitors (ACEI), angiotensin-II-receptor antagonists (ARB) and angiotensin receptor blocker/neprilysin inhibitor (ARNI) use. METHODS AND RESULTS: ACEi and ARBs were generally used in 87.6% of all HF patients in 2012 (n=154 627); 84.5% in 2013 (n=170 861); 83.5% in 2014 (n=186 963); 81.6% in 2015 (n=198 844); 80.1% in 2016 (n=205 793); 78.0% in 2017 (n=212 152) and in 76.7% in 2018 (n=219 235). In a sub-analysis of patients with a medical procedure and/or examination using an I50.x ICD code accounted for in the given year, ACEi and ARBs were generally used in 99.3% in 2012 (n=63 250); 96% in 2013 (n=62 241); 95.2% in 2014 (n=64 414); 93.3% in 2015 (n=65 217); 91.8% in 2016 (n=65 236); 90.1% in 2017 (n=65 761) and in 88.6% in 2018 (n=66 332). In 2018, the majority of patients with HF were prescribed ramipril (n=49 909; 17.5%) and perindopril (n=44 332; 15.5%). The mostly prescribed ARBs in 2018 were telmisartan (n=18 669; 6.5%); losartan (n=13 935; 4.9%) and valsartan (n=4 849; 1.7%). In 24.5% of cases, ACEIs and ARBs were prescribed in a fixed combination with another drug. ARNI became gradually more prescribed from 2018 (n=9 659 in November 2020). CONCLUSION: In an analysis of ACEIs, ARBs and ARNIs utilization in all patients treated for heart failure in the given year in the whole country, we found a comparable rate of drug prescription in comparison with specific heart failure registries. This indicates a good translation of current standard of care into common clinical practice. Ramipril and perindopril remained the mostly prescribed ACEIs and telmisartan became the mostly prescribed ARB. Since 2018, ARNIs began to be widely prescribed.

AIMS: Sub-analysis of a retrospective nation-wide observational analysis of heart failure (HF) epidemiology reported to the Czech National Registry of Reimbursed Health Services between 2012 and 2018 aimed at beta-blockers (BBs) utilization. METHODS AND RESULTS: The beta-blockers were generally used in 81.8% of all patients treated for HF in 2012 (n=52 140); 81.8% in 2013 (n=53 058); 83.1% in 2014 (n=56 221); 82.1% in 2015 (n=57 421); 83.3% in 2016 (n=59 187); 82.2% in 2017 (60 058) and in 81.4% in 2018 (n=60 966). In 2018, the majority of patients treated for HF were prescribed metoprolol (22 974; 30.7%) and bisoprolol (21 001; 28%). Carvedilol was prescribed in 7 331 patients treated for HF (9.8%), nebivolol in 5 392 HF patients. Despite its primary indication, betaxolol was used in 2 341 patients treated for HF (3.1%). All other beta-blockers were used in less than 1% of HF patients. In some of the mostly used BBs, their prescription in patients treated for HF changed in the last years (metoprolol 32.4% in 2012, 30.7% in 2018; bisoprolol 20.3% in 2012, 28% in 2018; carvedilol 18.3% in 2012, 9.8% in 2018; nebivolol 2.5% in 2012, 7.2% in 2018; betaxolol 4.2% in 2012, 3.1% in 2018). CONCLUSION: In an analysis of beta-blockers utilization in all patients treated for heart failure in the given year in the whole country, we have found only slightly lower amount of drug prescription in comparison with specific heart failure registries. This indicates a good translation of current standard of care into common clinical practice. Metoprolol remained the mostly prescribed drug. The prescription of bisoprolol and nebivolol has increased at the expense of carvedilol.

AIMS: A retrospective nationwide observational analysis of diagnoses, procedures, and treatment reported to the Czech National Registry of Reimbursed Health Services between 2012 and 2018. METHODS AND RESULTS: Prevalence of heart failure (HF) patients increased from 176 496 (1679.4 per 100 000 population) in 2012 to 285 745 (2689.0 per 100 000 population) patients in 2018 (mean age 74.4 ± 12.8 years). In the last years, a stable incidence of HF patients was observed (544 per 100 000 population in 2016 vs. 551 per 100 000 population in 2018; P = 0.310). Mortality rate decreased from 20.55% in 2012 to 15.89% in 2018. The number of hospitalized patients remained similar (318.2 per 100 000 population in 2012 vs. 311.8 per 100 000 population in 2018; P = 0.479). The most used drugs were diuretics (173 295; 60.6%) and beta-blockers (178 823; 62.6%), followed by angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers (angiotensin-converting enzyme inhibitors 120.581; 42.2%; angiotensin II receptor blockers 47 216; 16.5%). Even though the whole number of implanted devices in HF patients increased steadily (from 25 205 in 2012 to 45 363 in 2018), the prevalence of all devices (pacemakers and defibrillators) in the HF patients remained about the same (14.3% in 2012; 15.9% in 2018). CONCLUSIONS: The study included all patients with HF in the Czech Republic. These are the first nationwide data of HF epidemiology in the Eastern bloc. The incidence of HF remains stable in the last years. Due to aging of the population, the prevalence of HF significantly increased in the last 6 years. Despite a continuous increase in the prevalence of HF and a suboptimal utilization of its pharmacological therapy, mortality decreased, and the number of hospitalized patients remained the same.

This study evaluates the effects of chronic treatment with EET-A, an orally active epoxyeicosatrienoic acid (EETs) analog, on the course of aorto-caval fistula (ACF)-induced heart failure (HF) in Ren-2 transgenic rats (TGR), a model characterized by hypertension and augmented activity of the renin-angiotensin system (RAS). The results were compared with standard pharmacological blockade of the RAS using angiotensin-converting enzyme inhibitor (ACEi). The rationale for employing EET-A as a new treatment approach is based on our findings that apart from increased RAS activity, untreated ACF TGR also shows kidney and left ventricle (LV) tissue deficiency of EETs. Untreated ACF TGR began to die 17 days after creating ACF and were all dead by day 84. The treatment with EET-A alone or ACEi alone improved the survival rate: in 156 days after ACF creation, it was 45.5% and 59.4%, respectively. The combined treatment with EET-A and ACEi appeared to improve the final survival to 71%; however, the difference from either single treatment regimen did not reach significance. Nevertheless, our findings support the notion that targeting the cytochrome P-450-dependent epoxygenase pathway of arachidonic acid metabolism should be considered for the treatment of HF.
