Impact of the number of modifiable risk factors on clinical outcomes after percutaneous coronary intervention: An analysis from the e-Ultimaster registry.

Aims: A substantial proportion of the patients undergoing percutaneous coronary intervention (PCI) have none of the of standard modifiable cardiovascular risk factors (SMuRFs): hypertension, diabetes, hypercholesterolaemia and smoking. The aim of this analysis was to compare clinical outcomes after PCI according to the number of SMuRFs. Methods: Patients with an indication for a PCI were stratified based upon the number of SMuRFs: 0, 1, 2 or 3-4. The primary outcome was target lesion failure (TLF), a composite of cardiac death, target vessel-related myocardial infarction or clinically driven target lesion revascularization at 1-year. Inverse weighted propensity score (IWPS) adjustment was performed to adjust for differences in baseline characteristics. Results: The prevalence of SMuRFs was: 0 SMuRF 16.4 %; 1 SMuRF 27.8 %; 2 SMuRFs 34.7 % and 3-4 SMuRFs 21.1 %. Patients without SMuRFs were younger, more likely to be male and had less complex coronary artery disease. The incidence of TLF increased with the number of SMuRFs: 2.65 %, 2.75 %, 3.23 %, and 4.24 %, Ptrend < 0.001. The relative risk (RR) for a TLF was 60 % higher (95 % confidence interval 1.32-1.93, p < 0.01) for patients with 3-4 SMuRFs compared to patients without SMuRFs. The trend remained (Ptrend < 0.01) after IWPS with TLF rates of 2.88 %, 2.64 %, 2.88 % and 3.65 %. The RR for a TLF was 27 % higher (95 % CI 1.05-1.53, p < 0.01). Conclusion: The incidence of clinical events at 1-year increased with the number of SMuRFs. While patients without SMuRFs have a relatively favourable risk profile, more research is needed to optimize therapeutic management in the majority of patients.

Cangrelor - Expanding therapeutic options in patients with acute coronary syndrome.

Cangrelor is the only intravenous P2Y12 receptor antagonist. It is an adenosine triphosphate analog that selectively, directly, and reversibly binds to the platelet P2Y12 receptors exerting its antiaggregatory effect. Cangrelor is characterized by linear, dose-dependent pharmacokinetics and rapid onset of action providing potent platelet inhibition exceeding 90%. Cangrelor is rapidly metabolized by endothelial endonucleotidase; thus, its half-life is 2.9 to 5.5 min, and its antiplatelet effect subsides within 60 to 90 min. Data originating from three pivotal cangrelor trials (CHAMPION PLATFORM, CHAMPION PCI, and CHAMPION PHOENIX) indicate that cangrelor reduces the risk of periprocedural thrombotic complications during percutaneous coronary intervention at the expense of mild bleedings. Its unique pharmacological properties allow it to overcome the limitations of oral P2Y12 receptor inhibitors, mainly related to the delayed and decreased bioavailability and antiplatelet effect of these agents, which are often observed in the setting of acute coronary syndrome. Subgroups of patients who could theoretically benefit the most from cangrelor include those in whom pharmacokinetics and pharmacodynamics of oral P2Y12 receptor antagonists are most disturbed, namely patients with ST-segment elevation myocardial infarction, those treated with opioids, with mild therapeutic hypothermia, or in cardiogenic shock. Cangrelor could also be useful if bridging is required in patients undergoing surgery. According to the current guidelines cangrelor may be considered in P2Y12 receptor inhibitor-naïve patients undergoing percutaneous coronary intervention in both acute and stable settings.

Risks and benefits of renal artery stenting in fibromuscular dysplasia: Lessons from the ARCADIA-POL study.

INTRODUCTION: Although renal stenting is the standard revascularization method for atherosclerotic renal artery stenosis (RAS) (FMD-RAS), stenting in fibromuscular dysplasia (FMD) RAS is usually limited to periprocedural complications of angioplasty and primary arterial dissection. The main aim of the study was to retrospectively analyze the immediate and long-term results of renal stenting versus angioplasty in patients with FMD. METHODS: Of 343 patients in the ARCADIA-POL registry, 58 patients underwent percutaneous treatment due to FMD-RAS (in 70 arteries). Percutaneous transluminal renal angioplasty (PTRA) was performed as an initial treatment in 61 arteries (PTRA-group), whereas primary stenting was undertaken in nine arteries (stent-group). Stent-related complications were defined as: in-stent restenosis > 50% (ISR); stent fracture; under-expansion; or migration. RESULTS: In the PTRA-group, the initial restenosis rate was 50.8%. A second procedure was then performed in 22 arteries: re-PTRA (12 arteries) or stenting (10 arteries). The incidence of recurrent restenosis after re-PTRA was 41.7%. Complications occurred in seven of 10 (70%) arteries secondarily treated by stenting: two with under-expansion and five with ISR. In the stent-group, stent under-expansion occurred in one case (11.1%) and ISR in three of nine stents (33.3%). In combined analysis of stented arteries, either primarily or secondarily, stent-related complications occurred in 11/19 stenting procedures (57.9%): three due to under-expansion and eight due to ISRs. Finally, despite several revascularization attempts, four of 19 (21%) stented arteries were totally occluded and one was significantly stenosed at follow-up imaging. CONCLUSION: Our study indicates that renal stenting in FMD-RAS may carry a high risk of late complications, including stent occlusion. Further observational data from large-scale registries are required.

Impact of Complete Revascularization in the ISCHEMIA Trial.

BACKGROUND: Anatomic complete revascularization (ACR) and functional complete revascularization (FCR) have been associated with reduced death and myocardial infarction (MI) in some prior studies. The impact of complete revascularization (CR) in patients undergoing an invasive (INV) compared with a conservative (CON) management strategy has not been reported. OBJECTIVES: Among patients with chronic coronary disease without prior coronary artery bypass grafting randomized to INV vs CON management in the ISCHEMIA (International Study of Comparative Health Effectiveness with Medical and Invasive Approaches) trial, we examined the following: 1) the outcomes of ACR and FCR compared with incomplete revascularization; and 2) the potential impact of achieving CR in all INV patients compared with CON management. METHODS: ACR and FCR in the INV group were assessed at an independent core laboratory. Multivariable-adjusted outcomes of CR were examined in INV patients. Inverse probability weighted modeling was then performed to estimate the treatment effect had CR been achieved in all INV patients compared with CON management. RESULTS: ACR and FCR were achieved in 43.4% and 58.4% of 1,824 INV patients. ACR was associated with reduced 4-year rates of cardiovascular death or MI compared with incomplete revascularization. By inverse probability weighted modeling, ACR in all 2,296 INV patients compared with 2,498 CON patients was associated with a lower 4-year rate of cardiovascular death or MI (difference -3.5; 95% CI: -7.2% to 0.0%). In comparison, the event rate difference of cardiovascular death or MI for INV minus CON in the overall ISCHEMIA trial was -2.4%. Results were similar but less pronounced with FCR. CONCLUSIONS: The outcomes of an INV strategy may be improved if CR (especially ACR) is achieved.

Valve-in-valve transcatheter transfemoral mitral valve implantation (ViV-TMVI): Characteristics and early results from nationwide registry.

BACKGROUND: Valve-in-valve transcatheter transfemoral mitral valve implantation (ViV-TMVI) is an emerging treatment alternative to reoperation in high surgical risk patients with a failed mitral bioprostheses. AIM: To describe characteristics and evaluate 30-day outcomes of ViV-TMVI in the Polish population. METHODS: Nationwide registry was initiated to collect data of all patients with failed mitral bioprosthesis undergoing ViV-TMVI in Poland. This study presents 30-days clinical and echocardiographic follow-up. RESULTS: Overall, 27 ViV-TMVI were performed in 8 centers until May 2022 (85% since 2020). Mean (standard deviation [SD]) age was 73 (11.6) years with the median (interquartile range [IQR]) STS score of 5.3% (4.3%-14.3%). Mean (SD) time between surgical implantation and ViV-TMVI was 8.2 (3.2) years. Failed Hancock II (29%) and Perimount Magna (22%) were most frequently treated. Mechanisms of failure were equally often pure mitral regurgitation or stenosis (both 37%) with mixed etiology in 26%. Balloon-expandable Sapien 3/Ultra were used in all but 1 patient. Technical success was 96.3% (1 patient required additional prosthesis). Mean (SD) transvalvular mitral gradient reached 6.7 (2.2) mm Hg and mitral valve area was 1.8 (0.4) cm². None of the patients had moderate or severe mitral regurgitation with only 14.8% graded as mild. In 92.6% device success (2 patients had mean gradient ≥10 mm Hg) and in 85.6% procedural success was present. There were no deaths, cerebrovascular events or need for mitral valve surgery during 30-day follow-up. CONCLUSIONS: In short-term observation ViV-TMVI is safe and effective alternative for patients with failed mitral bioprosthesis at high surgical risk of re-operation. Longer observations on larger sample are warranted.

Impact of Enterococci vs. Staphylococci Induced Infective Endocarditis after Transcatheter Aortic Valve Implantation.

BACKGROUND: The two most common organisms found in infective endocarditis following transcatheter aortic valve implantation (TAVI-IE) are enterococci (EC-IE) and staphylococci (SC-IE). We aimed to compare clinical characteristics and outcomes of patients with EC-IE and SC-IE. METHODS: TAVI-IE patients from 2007 to 2021 were included in this analysis. The 1-year mortality was the primary outcome measure of this retrospective multi-center analysis. RESULTS: Out of 163 patients, 53 (32.5%) EC-IE and 69 (42.3%) SC-IE patients were included. Subjects were comparable with regard to age, sex, and clinically relevant baseline comorbidities. Symptoms at admission were not significantly different between groups, except for a lower risk for presenting with septic shock in EC-IE than SC-IE. Treatment was performed in 78% by antibiotics alone and in 22% of patients by surgery and antibiotics, with no significant differences between groups. The rate of any complication, in particular heart failure, renal failure, and septic shock during treatment for IE, was lower in EC-IE compared with SC-IE (p < 0.05). In-hospital (EC-IE: 36% vs. SC-IE: 56%, p = 0.035) and 1-year mortality (EC-IE: 51% vs. SC-IE: 70%, p = 0.009) were significantly lower in EC-IE compared with SC-IE. CONCLUSIONS: EC-IE, compared with SC-IE, was associated with a lower morbidity and mortality. However, absolute numbers are high, a finding that should trigger further research in appropriate perioperative antibiotic management and improvement of early IE diagnosis in the case of clinical suspicion.

Tetralogia de Fallot Associada a Artéria Subclávia Direita Aberrante. Implicações Clínicas / Tetralogy of Fallot Associated with Aberrant Right Subclavian Artery. Clinical Implications

Resumo Desde a primeira descrição da tetralogia de Fallot (ToF) em 1671 por Niels Stensen e em 1888 por Étienne-Louis Arthur Fallot, vários trabalhos relataram essa anomalia juntamente com suas variantes e anomalias cardiovasculares concomitantes. A artéria subclávia direita aberrante (ASDA) é a anomalia do arco aórtico mais comum. Diferentemente da artéria subclávia esquerda aberrante, a ocorrência de ASDA em pacientes com ToF só foi relatada casuisticamente. Apresentamos dois pacientes de ToF com ASDA. É importante notar que o conhecimento da coexistência das duas anomalias tem pontos muito práticos durante correções endovasculares ou cirúrgicas de defeitos cardíacos congênitos (inclusive ToF).

Abstract Since the first description of Tetralogy of Fallot (ToF) in 1671 by Niels Stensen and in 1888 by Étienne-Louis Arthur Fallot, numerous papers have reported on this anomaly, along with its variants and concomitant cardiovascular anomalies. Aberrant right subclavian artery (ARSA) is the most common anomaly of the aortic arch. Different from the left aberrant subclavian artery, occurrence of ARSA in ToF-patients has only casuistically been reported so far. The present study reports on two ToF-patients with ARSA. It is important to note that knowledge of the coexistence of both anomalies has highly practical points during surgical or endovascular corrections of congenital heart defects (including ToF).

Geographic disparity in 10-year mortality after coronary artery revascularization in the SYNTAXES trial.

AIMS: To investigate geographic disparity in long-term mortality following revascularization in patients with complex coronary artery disease (CAD). METHODS AND RESULTS: The SYNTAXES trial randomized 1800 patients with three-vessel and/or left main CAD to percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and assessed their survival at 10 years. Patients were stratified according to the region of recruitment: North America (N-A, n = 245), Eastern Europe (E-E, n = 189), Northern Europe (N-E, n = 425), Southern Europe (S-E, n = 263), and Western Europe (W-E, n = 678), which also served as the reference group. Compared to W-E, patients were younger in E-E (62 vs 65 years, p < 0.001), and less frequently male in N-A (65.3% vs 79.6%, p < 0.001). Diabetes (16.0% vs 25.4%, p < 0.001) and peripheral vascular disease (6.8% vs 10.9%, p = 0.025) were less frequent in N-E than W-E. Ejection fraction was highest in W-E (62% vs 56%, p < 0.001). Compared to W-E, the mean anatomic SYNTAX score was higher in S-E (29 vs 31, p = 0.008) and lower in N-A (26, p < 0.001). Crude ten-year mortality was similar in N-A (31.6%), and W-E (30.7%), and significantly lower in E-E (22.5%, p = 0.041), N-E (21.9%, p = 0.003) and S-E (22.0%, p = 0.014). Compared to W-E, adjusted mortality in N-E (HR 0.85, p = 0.019) and S-E (HR 0.72, p = 0.043) remain significantly lower after adjustment for pre- and peri-procedural factors, but no significant interaction (Pinteraction = 0.728) between region and modality of revascularization was seen. CONCLUSION: In the era of globalization, knowledge, and understanding of geographic disparity are of paramount importance for the correct interpretation of global studies.

Comparison of long-term outcomes and risk factors of aortic stenosis treatment in patients undergoing transcatheter aortic valve implantation and surgical aortic valve replacement.

BACKGROUND: Aortic stenosis (AS) is the most common valvular heart disease and untreated has a bleak prognosis. The only effective method of treatment is valve replacement, surgical (SAVR), or transcatheter (TAVI). AIMS: We decided to analyze outcomes and predictors of long-term mortality in patients undergoing TAVI and SAVR. METHODS: A retrospective analysis of 1229 patients with advanced AS, comprising TAVI (n = 211), SAVR (n = 556), SAVR, and additional procedures (n = 462), operated on from 2014 to 2018, was performed. RESULTS: No significant differences between SAVR and TAVI were found for 24-month mortality in groups of consecutive patients. Postoperative stroke or transient ischemic attack (TIA), chronic obstructive pulmonary disease (COPD), and transfusion of red blood cells (RBCs) were independent predictors of 1-year mortality after SAVR. The above-mentioned factors regarding the increased estimated surgery risk in the EuroSCORE II ( > 4%) were predictors of 2-years mortality after SAVR. Risk factors for 6- and 12-month mortality after TAVI were EuroSCORE II, new onset of atrial fibrillation (NOAF), and the increased RBC distribution width (RDW). Postoperative respiratory failure was an independent risk factor for 6-, 12- and 24-month mortality in both groups of patients. CONCLUSIONS: There were no significant differences regarding prognosis after TAVI and SAVR at the 24-month follow-up in the propensity score matching model. Independent predictive factors of late mortality after both procedures were EuroScore II and respiratory failure. Independent predictive factors of late mortality specific for TAVI were NOAF, increased RDW, and for SAVR: TIA, stroke, COPD, and RBC transfusion.

Management and predictors of clinical events in 75 686 patients with acute myocardial infarction.

BACKGROUND: Although mortality in patients with acute myocardial infarction (MI) has decreased substantially over the last few decades in many countries, MI remains a major threat to public health. AIMS: To assess the number and outcomes of patients hospitalized for acute MI in Poland in 2018 as well as proportions of patients participating in cardiac rehabilitation and undergoing invasive cardiac procedures following discharge. METHODS: We used public databases. We included all patients hospitalized for acute MI in Poland in 2018 and assessed event-free survival along with uptake of invasive cardiac procedures, cardiac rehabilitation, and consultations with cardiologists. RESULTS: A total of 75868 patients (mean age, 68.8 years) were hospitalized for acute MI in Poland in 2018 (the admission rate, 197.0 per 100000 inhabitants). In-hospital mortality was 8.4%, while one-year mortality was 17.3% (one-year post-discharge mortality was 9.8%). Approximately 75% and 96% of discharged patients consulted a general practitioner, whereas 12% and 62% consulted a cardiologist, 5% and 19% underwent percutaneous coronary intervention, 0.6% and 2.9% un-derwent coronary artery bypass grafting, while 0.04% and 1.9% had an implantable cardioverter defibrillator implanted within 30 days and 365 days following discharge. The participation rate in cardiac rehabilitation within the first 14 days following discharge was 11%, within the first 30 days was 19%, and within 365 days was 35%. CONCLUSIONS: In-hospital and post-discharge mortality is still high in Poland. The access to cardiac consultations and cardiac rehabilitation following MI is insufficient. There is considerable potential for a further decrease in mortality in patients suffering from MI in Poland.

Transcatheter aortic valve­in­valve implantation for failed surgical bioprostheses: results from the Polish Transcatheter Aortic Valve-in-Valve Implantation (ViV­TAVI) Registry

INTRODUCTION: Transcatheter aortic valve­in ­valve implantation (ViV­TAVI) has emerged as an alternative to redo surgery in patients with failed surgical aortic bioprosthesis. OBJECTIVES: We evaluated the safety and efficacy of ViV­TAVI in Polish patients after surgical aortic valve replacement. PATIENTS AND METHODS: This was a nationwide multicenter registry of ViV­TAVI procedures. Data were collected using an online form, and the clinical follow ­up lasted 1 year. RESULTS: From 2008 to 2020, 130 ViV­TAVI procedures were performed (1.9% of all transcatheter aortic valve implantation [TAVI] cases). A considerable increase in ViV­TAVI procedures since 2018 has been observed (n = 59, 45% of ViV­TAVI cases). Hancock II, Freestyle, and homograft were the most frequently treated bioprostheses. The self ­expanding supra ­annular Corevalve / Evolut valve was used in 76% of cases. In 21% of cases, the mean postprocedural pressure gradient (PG) exceeded 20 mm Hg. All­cause mortal­ity at 1 year was 10.8%. Aortic valve stenosis was associated with a higher mean PG than aortic valve regurgitation or mixed disease (P = 0.004). Supra ­annular transcatheter aortic valves were associated with lower mean PGs than intra ­annular valves (P = 0.004). Second ­generation devices were associated with shorter procedure time (120 min vs 135 min, P = 0.04), less frequent need for additional TAVI (2% vs 10%, P = 0.04), and lower 1­year cardiovascular mortality (95% vs 82.8%, P = 0.03) than first­generation valves. CONCLUSIONS: Transcatheter treatment of failed bioprostheses is increasingly common, with the best hemodynamic effect shown for supra ­annular valves. The introduction of second­generation valves has improved procedural and clinical outcomes.

Optimal medical therapy in patients with stable coronary artery disease in Poland: the ISCHEMIA trial experience.

Introduction: Optimal medical therapy (OMT) is the cornerstone of treatment for stable coronary disease with the ISCHEMIA trial showing similar outcomes using OMT with or without an initial invasive approach. Objectives: To describe OMT goal attainment in Polish ISCHEMIA participants compared with other countries. Patients and methods: Among 5179 trial participants, 333 were randomized in Poland. The median follow-up was 3.2 years. OMT targets were: not smoking, high-intensity statin therapy, low-density lipoprotein cholesterol (LDL-C) of less than 70 mg/dl, systolic blood pressure of less than 140 mm Hg, aspirin therapy, and ACEI / ARB, and ß-blocker therapy if indicated. Results: Compared with 36 other countries, at randomization, patients in Poland were older (67 [62­75] y vs 65 [58­71] y); P <⁠0.001), more often female (30% vs 22%; P = 0.002), with a longer history of angina (3 [1­9] y vs 1 [0­3] y; P <⁠0.001), and there were more cases of prior myocardial infarction (32% vs 18%; P <⁠0.01) and revascularization (PCI, 40% vs 19%; CABG, 11% vs 3%; P <⁠0.001 for both). The number of OMT goals attained increased from baseline to follow-up visits (5 [4­5] vs 6 [5­6]; P <⁠0.001) in Poland and other countries alike (P = 0.89 vs P = 0.14). In Poland, significant improvements were achieved regarding high-intensity statin therapy (27% vs 50%), LDL-C <⁠70 mg/dl (29% vs 65%), and systolic blood pressure of less than 140 mm Hg (63% vs 81%) (P <⁠0.001 for all), whereas not-smoking (89% vs 89%), aspirin (90% vs 88%), ACEI / ARB (93% vs 95%), and ß-blocker therapy (94% vs 90%) remained high. Conclusions: With regular surveillance and contemporary medical therapy, high OMT goal attainment was achievable among the participants of the ISCHEMIA trial in Poland relative to other countries. There is still room for improvement in LDL-C and blood pressure management.

Ten-year all-cause death after percutaneous or surgical revascularization in diabetic patients with complex coronary artery disease.

AIMS: The aim of this article was to compare rates of all-cause death at 10 years following coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI) in patients with or without diabetes. METHODS AND RESULTS: The SYNTAXES study evaluated up to 10-year survival of 1800 patients with three-vessel disease (3VD) and/or left main coronary artery disease (LMCAD) randomized to receive either PCI or CABG in the SYNTAX trial. Ten-year all-cause death according to diabetic status and revascularization strategy was examined. In diabetics (n = 452), the risk of mortality was numerically higher with PCI compared with CABG at 5 years [19.6% vs. 13.3%, hazard ratio (HR): 1.53, 95% confidence interval (CI): 0.96, 2.43, P = 0.075], with the opposite seen between 5 and 10 years (PCI vs. CABG: 20.8% vs. 24.4%, HR: 0.82, 95% CI: 0.52, 1.27, P = 0.366). Irrespective of diabetic status, there was no significant difference in all-cause death at 10 years between patients receiving PCI or CABG, the absolute treatment difference was 1.9% in diabetics (PCI vs. CABG: 36.4% vs. 34.5%, difference: 1.9%, 95% CI: -7.6%, 11.1%, P = 0.551). Among insulin-treated patients (n = 182), all-cause death at 10 years was numerically higher with PCI (47.9% vs. 39.6%, difference: 8.2%, 95% CI: -6.5%, 22.5%, P = 0.227). CONCLUSIONS: The treatment effects of PCI vs. CABG on all-cause death at 10 years in patients with 3VD and/or LMCAD were similar irrespective of the presence of diabetes. There may, however, be a survival benefit with CABG in patients with insulin-treated diabetes. The association between revascularization strategy and very long-term ischaemic and safety outcomes for patients with diabetes needs further investigation in dedicated trials.

Mechanisms, Prevention and Treatment of Saphenous Vein Graft Disease.

Saphenous vein grafts are imperfect yet indispensable conduits commonly used for coronary artery bypass grafting. Their degeneration ultimately leading to occlusion results from the pathological response of the vein to altered blood rheology and several types of vascular injury. Surgical techniques minimizing vessel damage, and prolonged antiplatelet and lipid-lowering treatment are established methods of mitigating the degeneration process hence preventing graft occlusions. Percutaneous interventions in degenerated vein grafts carry high risk of embolization, periprocedural myocardial infarction and restenosis. Thus, native vessel should be the preferred treatment target in case of graft failure whenever technically feasible.

Ultrasound renal denervation for hypertension resistant to a triple medication pill (RADIANCE-HTN TRIO): a randomised, multicentre, single-blind, sham-controlled trial.

BACKGROUND: Endovascular renal denervation reduces blood pressure in patients with mild-to-moderate hypertension, but its efficacy in patients with true resistant hypertension has not been shown. We aimed to assess the efficacy and safety of endovascular ultrasound renal denervation in patients with hypertension resistant to three or more antihypertensive medications. METHODS: In a randomised, international, multicentre, single-blind, sham-controlled trial done at 28 tertiary centres in the USA and 25 in Europe, we included patients aged 18-75 years with office blood pressure of at least 140/90 mm Hg despite three or more antihypertensive medications including a diuretic. Eligible patients were switched to a once daily, fixed-dose, single-pill combination of a calcium channel blocker, an angiotensin receptor blocker, and a thiazide diuretic. After 4 weeks of standardised therapy, patients with daytime ambulatory blood pressure of at least 135/85 mm Hg were randomly assigned (1:1) by computer (stratified by centres) to ultrasound renal denervation or a sham procedure. Patients and outcome assessors were masked to randomisation. Addition of antihypertensive medications was allowed if specified blood pressure thresholds were exceeded. The primary endpoint was the change in daytime ambulatory systolic blood pressure at 2 months in the intention-to-treat population. Safety was also assessed in the intention-to-treat population. This study is registered with ClinicalTrials.gov, NCT02649426. FINDINGS: Between March 11, 2016, and March 13, 2020, 989 participants were enrolled and 136 were randomly assigned to renal denervation (n=69) or a sham procedure (n=67). Full adherence to the combination medications at 2 months among patients with urine samples was similar in both groups (42 [82%] of 51 in the renal denervation group vs 47 [82%] of 57 in the sham procedure group; p=0·99). Renal denervation reduced daytime ambulatory systolic blood pressure more than the sham procedure (-8·0 mm Hg [IQR -16·4 to 0·0] vs -3·0 mm Hg [-10·3 to 1·8]; median between-group difference -4·5 mm Hg [95% CI -8·5 to -0·3]; adjusted p=0·022); the median between-group difference was -5·8 mm Hg (95% CI -9·7 to -1·6; adjusted p=0·0051) among patients with complete ambulatory blood pressure data. There were no differences in safety outcomes between the two groups. INTERPRETATION: Compared with a sham procedure, ultrasound renal denervation reduced blood pressure at 2 months in patients with hypertension resistant to a standardised triple combination pill. If the blood pressure lowering effect and safety of renal denervation are maintained in the long term, renal denervation might be an alternative to the addition of further antihypertensive medications in patients with resistant hypertension.

Impact of chronic obstructive pulmonary disease on 10-year mortality after percutaneous coronary intervention and bypass surgery for complex coronary artery disease: insights from the SYNTAX Extended Survival study.

AIMS: To evaluate the impact of chronic obstructive pulmonary disease (COPD) on 10-year all-cause death and the treatment effect of CABG versus PCI on 10-year all-cause death in patients with three-vessel disease (3VD) and/or left main coronary artery disease (LMCAD) and COPD. METHODS: Patients were stratified according to COPD status and compared with regard to clinical outcomes. Ten-year all-cause death was examined according to the presence of COPD and the revascularization strategy. RESULTS: COPD status was available for all randomized 1800 patients, of whom, 154 had COPD (8.6%) at the time of randomization. Regardless of the revascularization strategy, patients with COPD had a higher risk of 10-year all-cause death, compared with those without COPD (43.1% vs. 24.9%; hazard ratio [HR]: 2.03; 95% confidence interval [CI]: 1.56-2.64; p < 0.001). Among patients with COPD, CABG appeared to have a slightly lower risk of 10-year all-cause death compared with PCI (42.3% vs. 43.9%; HR: 0.96; 95% CI: 0.59-1.56, p = 0.858), whereas among those without COPD, CABG had a significantly lower risk of 10-year all-cause death (22.7% vs. 27.1%; HR: 0.81; 95% CI: 0.67-0.99, p = 0.041). There was no significant differential treatment effect of CABG versus PCI on 10-year all-cause death between patients with and without COPD (p interaction = 0.544). CONCLUSIONS: COPD was associated with a higher risk of 10-year all-cause death after revascularization for complex coronary artery disease. The presence of COPD did not significantly modify the beneficial effect of CABG versus PCI on 10-year all-cause death. TRIAL REGISTRATION: SYNTAX: ClinicalTrials.gov reference: NCT00114972.

Expert opinion of the Heart Failure Working Group of the Polish Cardiac Society on the use of dapagliflozin in the treatment of heart failure with reduced ejection fraction.

Heart failure (HF) is a global health problem inherent in an aging population with coexisting cardiovascular diseases. Based on data from the Polish National Health Fund (Polish, Narodowy Fundusz Zdrowia), approximately 1.2 million people in Poland currently suffer from HF, and 140 000 of them die annually. Recently, Poland was ranked fifth among the European Union countries regarding the number of patients with diagnosed HF and first in terms of the number of HF hospitalizations (547 per 100 000 population) among 34 countries associated in the Organization for Economic Cooperation and Development. In recent years, a significant progress has been made in the diagnosis and treatment of HF with reduced left ventricular ejection fraction (HFrEF), which has resulted in a reduction in cardiovascular and total mortality. Despite these advantages, 5-year survival in the course of HF is still worse than that observed in some types of cancer, both in the populations of men and women. Hence, the search for drugs improving the prognosis in this group of patients is still ongoing. Sodium-glucose cotransporter 2 inhibitors represent a new group of drugs that will undoubtedly be a milestone in the treatment of patients with HFrEF. This expert opinion covers the history of dapagliflozin, which, from a drug dedicated to the treatment of type 2 diabetes, has become one of the most effective drugs improving prognosis and quality of life as well as reducing the number of hospitalizations in patients with HF. This document presents the opinion from the experts of the Heart Failure Working Group of the Polish Cardiac Society on the most relevant studies on dapagliflozin and indications for its use.
