Hemodynamic parameters of aortic valve prostheses - KRAK-AS registry analysis.

Introduction: The treatment of choice for aortic stenosis is a valve replacement. Some patients have post-procedural increased pressure gradient on the implanted prosthesis because of patient-prosthesis mismatch (PPM), known to adversely influence prognosis. The PPM risk should be initially predicted and effort made to avoid this complication, specifically in large body size patients. Aim: To assess the frequency of PPM taking into account the valvular prosthesis type in a real-life population of consecutive patients included in the Krakow aortic stenosis registry. Material and methods: The KRAK-AS registry was conducted in July-October 2016. Patients were assessed before and after valve surgery and during the 3-year follow-up. Patients who underwent aortic valve intervention were clinically and echocardiographically evaluated within a month after surgery and divided into groups depending on the implanted prosthesis type. Analysis of patients with a smaller (< 23 mm) and larger than median (≥ 23 mm) valve diameter was performed. Results: The valve implantation was performed in 229 patients (42 mechanical, 139 biological, 48 transcatheter). No differences between patient groups compared by PPM occurrence was seen at baseline. Median age was 70 years; 55.5% were men. At least moderate PPM (iEOA ≤ 0.85 cm2/m2) was observed in 40% of mechanical valves, 33% of biological valves, and was significantly less frequent (10%) in patients after transcatheter valve implantation, p = 0.0001. Severe PPM (iEOA < 0.65 cm2/m2) was found in 17.6% of mechanical valve PPM patients, 4.3% of biological ones, and no patients after transcatheter procedure. Conclusions: PPM is a frequent phenomenon in the real-life population of patients undergoing surgical aortic valve replacement, being significantly less frequent in the case of a transcatheter procedure.

Screening diagnosis of dementia in patients following heart failure decompensation is associated with a higher relative wall thickness.

BACKGROUND: The usefulness of echocardiographic characteristics for dementia prediction in patients with heart failure decompensation (HFD) is not determined. Therefore, we sought to investigate the echocardiographic features of patients with HFD and screening diagnosis of dementia (SDD). METHODS: 139 patients aged over 65 years were hospitalized with the diagnosis of HFD. Clinical characteristics and echocardiographic characteristics were recorded during hospitalization. SDD was defined based on the result of ALFI- MMSE of <17 points. RESULTS: Patients with SDD were older (p=0.013), had thicker IVSd (p=0.021), thicker PWd (p=0.005) and had a higher RWT (0.40 vs 0.35, p=0.004) than patients without SDD, without differences in LVMI (p=0.13). There was no correlation between RWT and LVMI (r=-0.01, p=0.88). In the multivariate analysis, an older age (ß=-0.116, 95% CI -0.224 - -0.008, p=0.035, per year) and a higher RWT (ß=-0.069, 95% CI -0.137 - -0.002, p=0.045, per 0.01) influenced a lower ALFI-MMSE. For a prediction of SDD, the RWT reached the area under a ROC curve of 0.67 (95% CI 0.56-0.77, p=0.004 with sensitivity of 60% and specificity of 70% for RWT of ≥0.375). CONCLUSIONS: Apart from age, RWT reflecting left ventricular geometry changes but not hypertrophy was independently but moderately associated with SDD in patients following HFD (Tab. 4, Fig. 1, Ref. 35).

Statin Use in Cancer Patients with Acute Myocardial Infarction and Its Impact on Long-Term Mortality.

Statin use and its impact on long-term clinical outcomes in active cancer patients following acute myocardial infarction (MI) remains insufficiently elucidated. Of the 1011 consecutive acute MI patients treated invasively between 2012 and 2017, cancer was identified in 134 (13.3%) subjects. All patients were observed within a median follow-up of 69.2 (37.8−79.9) months. On discharge, statins were prescribed less frequently in MI patients with cancer as compared to the non-cancer MI population (79.9% vs. 91.4%, p < 0.001). The most common statin in both groups was atorvastatin. The long-term mortality was higher in MI patients not treated vs. those treated with statins, both in non-cancer (29.5%/year vs. 6.7%/year, p < 0.001) and cancer groups (53.9%/year vs. 24.9%/year, p < 0.05), respectively. Patient's age (hazard ratio (HR) 1.04, 95% confidence interval (CI) 1.03−1.05, p < 0.001, per year), an active cancer (HR 2.42, 95% CI 1.89−3.11, p < 0.001), hemoglobin level (HR 1.14, 95% CI 1.09−1.20, p < 0.001, per 1 g/dL decrease), and no statin on discharge (HR 2.13, 95% CI 1.61−2.78, p < 0.001) independently increased long-term mortality. In MI patients, simultaneous diagnosis of an active cancer was associated with less frequently prescribed statins on discharge. Irrespective of cancer diagnosis, no statin use was found as an independent predictor of increased long-term mortality.

Clinical Characteristics and Long-Term Outcomes of MINOCA Accompanied by Active Cancer: A Retrospective Insight Into a Cardio-Oncology Center Registry.

Background: Clinical characteristics and long-term outcomes of patients with myocardial infarction with non-obstructive coronary arteries (MINOCA) and cancer are insufficiently elucidated. Objectives: We sought to characterize these patients hospitalized in a tertiary cardio-oncology center and to find the potential determinants affecting their long-term mortality. Methods: MINOCA was diagnosed in 72 of the 1,011 patients with consecutive myocardial infarction who underwent coronary angiography. Mortality rates and their determinants were analyzed within a median follow-up of 69.2 (37.8-79.9) months. Results: Active cancer was identified in 21 (29.2%) of patients with MINOCA and in 113 (12.0%) patients with myocardial infarction and obstructive coronary artery disease (MI-CAD) (p < 0.001). MINOCA patients with cancer were characterized by a higher incidence of anemia (47.6 vs. 21.6%, p = 0.03) and more frequently Takotsubo syndrome (19.1 vs. 2.0%, p = 0.01) than in non-cancer MINOCA. The troponin T/hemoglobin ratio was higher in both cancer MINOCA and MI-CAD groups when compared with their respective non-cancer patients (both p < 0.05). The age and sex-standardized mortality rates were significantly higher in cancer MINOCA (26.7%/year) when compared with non-cancer MINOCA (2.3%/year, p = 0.002) and in cancer MI-CAD (25.0%/year) vs. non-cancer MI-CAD (3.7%/year, p < 0.001). Active cancer (HR 3.12, 95% CI 2.41-4.04) was independently associated with higher long-term mortality, while higher hemoglobin levels (HR 0.93, 95% CI 0.88-0.99, per g/dl) and a MINOCA diagnosis (HR 0.69, 95% CI 0.47-0.97) improved long-term survival. Conclusion: Patients with MINOCA were comorbid with cancer more frequently than MI-CAD. In turn, an active malignancy was associated with an unfavorable long-term survival both in MI-CAD population and in patients with MINOCA.

Prostacyclin analogues decrease platelet aggregation but have no effect on thrombin generation, fibrin clot structure, and fibrinolysis in pulmonary arterial hypertension: PAPAYA coagulation.

Prostacyclin (PGI2) analogues (epoprostenol, treprostonil, iloprost) are the cornerstone of pulmonary arterial hypertension (PAH) treatment. PGI2 analogues inhibit platelet reactivity, but their impact on coagulation and fibrinolysis parameters has not been elucidated. We compared platelet reactivity, thrombin generation, clot permeation, and lysis properties in patients with PAH treated with PGI2 analogues (n = 20) and those not receiving PGI2 analogues (n = 20). Platelet reactivity was lower in patients treated with PGI2 analogues, compared to the control group, as evaluated with arachidonic acid (ASPI), adenosine diphosphate (ADP), and thrombin receptor-activating peptide-6 (TRAP) tests (p = .009, p = .02, p = .007, respectively). In the subgroup analysis, both treprostinil and epoprostenol decreased platelet reactivity to the similar extent. There were no differences regarding thrombin generation, clot permeation, and lysis parameters in patients receiving and not receiving PGI2 analogues (p ≥ .60 for all). In the subgroup analysis, there were no differences regarding coagulation and fibrinolysis parameters between treprostinil, epoprostenol, and no PGI2 analogues. To conclude, patients with PAH treated with PGI2 analogues have reduced platelet reactivity, but similar clot formation and lysis parameters, compared to patients not receiving PGI2 analogues. Further randomized clinical trials are required to confirm these findings.

Dapagliflozin in the treatment of patients with heart failure with reduced left ventricular ejection fraction - a practical approach.

Because of its frequent occurrence, poor prognosis, low quality of life of patients accompanying the disease and high costs associated with treatment heart failure is a significant health problem in modern cardiology. The treatment of patients with heart failure and reduced ejection fraction (HFrEF) is supported by large-scale randomized clinical trials (RCTs), reflected in the ESC/HFA treatment recommendations. The use of ß-blockers, inhibitors of the renin-angiotensin aldosterone system (RAA), including angiotensin converting enzyme ACE/ARB inhibitors, angiotensin and neprilysin receptor blockers (ARNI) and mineralocorticoid receptor antagonists (MRA) have been a solid basis for triple HFrEF therapy over the last few years, partially altering the natural history of patients with HF. Despite this, the 5-year survival rate in HF is still lower than for some types of cancer. Therefore, the search for new drugs to improve the prognosis of this disease is still ongoing. A new group of drugs - the so-called flozins, i.e. - is a great hope for a change in the natural history of heart failure. The following article presents practical aspects of using these drugs in the treatment of patients with HFrEF, taking into account both the inclusion criteria and various clinical profiles of patients.

Changes over time in the prevention of recurrent coronary artery disease in everyday practice.

INTRODUCTION: Patients with coronary artery disease (CAD) are at high risk of recurrent cardiovascular events, and risk factor control is crucial in this population. OBJECTIVES: The aim of the study was to compare the implementation of the European Society of Cardiology guidelines regarding prevention of recurrent CAD in 2011 to 2013 with 2016 to 2017. PATIENTS AND METHODS: The study included 5 hospitals with cardiology departments serving the city of Kraków and its surrounding districts. Consecutive patients with established CAD were interviewed 6 to 18 months after hospitalization in the years 2011 to 2013 and 2016 to 2017. RESULTS: We examined 616 patients in 2011 to 2013 and 388 in 2016 to 2017 (mean [SD] age, 64.7 [8.8] years vs 66.4 [8.4] years; P <0.01). After adjusting for covariates, the proportion of patients with high blood pressure decreased by 8.9% (95% CI, -15.6% to -2.1%) and the proportion of patients with high level of low­ density lipoprotein cholesterol declined by 9.5% (95% CI, -16.7% to -2.2%) in 2016 to 2017 compared with 2011 to 2013, whereas the proportion of smoking patients (-0.2% [95% CI, -6% to 5.5%]) and those with high glucose levels (3.9% [95% CI, -2.2% to 10%]) and a body mass index of 25 kg/m2 or greater (3.8% [95% CI, -3.9% to 11.6%]) did not change. More patients were prescribed antiplatelets, ß­ blockers, angiotensin converting enzyme inhibitors or angiotensin II receptor blockers, calcium antagonists, and anticoagulants in the second period. CONCLUSIONS: We observed an increase in the proportion of patients with CAD who were prescribed cardiovascular drugs, and consequently a slight improvement in the control of their blood pressure and low­ density lipoprotein cholesterol. No changes were found regarding other main risk factors.

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.

Typical variant of takotsubo cardiomyopathy in oncological patients. Two case reports and review of the literature.

Takotsubo cardiomyopathy (TCM) represents an acute systolic left ventricular dysfunction typically triggered by severe psychological or physical stress. Oncological patients due to emotional distress of the diagnosis, proinflammatory and prothrombotic nature of cancer and also physical stress often following complex anticancer therapies are at high-risk of TCM. Moreover, there are also few reports of TCM associated with oncological treatment, mostly chemotherapy. Recent data from large registries indicate a surprisingly high incidence of malignancy in TCM, significant differences in clinical characteristics and unfavorable short- and long-term clinical outcomes in this specific group of patients. Therefore, we present two case reports of TCM that occurred during active anticancer therapy. Both women were admitted with suspicion of acute coronary syndrome. The first patient underwent mastectomy two years before due to hormone receptor-positive breast cancer and on admission she was during adjuvant hormonotherapy with tamoxifen. The admission of the second patient was preceded by fifteen fractions of adjuvant external beam radiotherapy due to intermediate-risk endometrial cancer after radical hysterectomy. Based on coronary angiography type I of acute coronary syndrome was excluded. Both patients negated stressful situations in the period immediately before the symptoms onset. Within hospital course baseline apical ballooning observed in both cases fully recovered and enabled subsequent completion of oncological treatment in accordance with adopted treatment protocols without recurrence of TCM. To our knowledge, presented cases are the first reports showing direct relationship between TCM and adjuvant hormonotherapy with tamoxifen or pelvic radiotherapy.

Palliative care for people living with cardiac disease.

Many cardiovascular diseases lead to heart failure, which is a progressive syndrome causing significant distress and limiting the quality of life, despite optimal cardiologic treatment. It is estimated that about 26 000 people in Poland suffer from advanced heart failure, and this number is growing. That is why palliative care (PC) dedicated to people living with end­stage cardiac diseases should be urgently implemented in Poland. Well­organized PC may not only relieve symptoms and improve quality of life in people living with cardiac diseases not responding to treatment but also support patients and their families during the dying process. Palliative care in patients with cardiac diseases should be continued during the end-of-life period. It should be implemented regardless of prognosis, and adjusted to patients' needs. Two approaches to PC are presented in this expert opinion. The first one (generic) is provided by all medical professionals incorporating PC principles into the usual patient care. The second approach, namely, specialized PC, is ensured by a multiprofessional team or at least a PC specialist who received appropriate training in PC. The model of needs-based (not prognosis-based) implementation of PC is discussed in this paper. Symptom control, support in decision-making, and sensitive, open communication are considered integral elements of PC interventions. Medical professionals developing PC in Poland should think about groups of patients with special needs like those with valvular heart disease, grown­up congenital heart disease, and pulmonary arterial hypertension, as well as elderly people. This consensus document presents main recommendations for future PC organization in Poland. Among others, we suggest changing the Polish National Health Fund reimbursement rules regarding PC and improving cardiologist education on PC.

Relationship among the leptin-to-adiponectin ratio, systemic inflammation, and anisocytosis in well-controlled type 2 diabetic patients with atherosclerotic cardiovascular disease.

BACKGROUND: Previous studies have shown that red blood cell distribution width (RDW) is an independent predictor of poor prognosis in type 2 diabetes (T2D) and atherosclerotic cardiovascular disease (ASCVD). The mechanisms underlying increased anisocytosis in patients with T2D and confirmed ASCVD remain poorly understood. AIMS: We sought to evaluate the relationship among the leptin-to-adiponectin ratio, systemic low -grade inflammation, and RDW in optimally treated patients with T2D and established ASCVD. METHODS: A total of 68 patients, aged 47 to 85 years (mean [SD], 65.3 [6.8] years) and including 21 women (30.9%), were enrolled and grouped according to median RDW into those with RDW <13.5% (n = 33) and those with RDW ≥13.5% (n = 35). RESULTS: Patients with RDW ≥13.5% had a significantly higher median (interquartile range [IQR]) serum leptin-to-adiponectin ratio (1.7 [0.49-2.3] ng/µg vs 0.66 [0.31-1.25] ng/µg; P = 0.04) and median (IQR) tumor necrosis factor α levels (1.58 [1.42-1.97] pg/ml vs 1.39 [1.18-1.57] pg/ml; P = 0.02). There were no significant differences in the concentrations of other inflammatory markers. The leptin-to-adiponectin ratio (r = 0.25; P = 0.04) and levels of tumor necrosis factor α (r = 0.32; P = 0.01) and soluble intercellular adhesion molecule 1 (r = 0.31; P = 0.01) were positively correlated with RDW, which was confirmed by univariate linear regression analysis. A multivariable regression model, which included demographic, clinical, and laboratory data, showed that white blood cell count (ß = 0.25; 95% CI, 0.05-0.45; P = 0.01), soluble intercellular adhesion molecule 1 levels (ß = 0.21; 95% CI, 0.02-0.41; P = 0.03), and mean corpuscular hemoglobin concentration (MCHC), (ß = -0.48; 95% CI, 0.67 to -0.28; P < 0.001) were independent predictors of RDW in our patients. CONCLUSIONS: In well-controlled patients with T2D and ASCVD, the RDW values are associated with leptin-to-adiponectin imbalance and selected inflammatory markers.

Coronary artery dissection following aortic valve replacement. How can one deal with this rare yet life-threatening complication?

Coronary artery dissection following its cannulation for cardioplegia administration as a result of aortic valve replacement (AVR) is a rare but nevertheless life-threatening complication. The three cases of a patient suffering from aortic stenosis illustrated below focus on the issue of how to identify and treat the dissected artery. In all of the patients who had undergone AVR diagnosed was a periprocedural myocardial infarction. Angiography revealed the dissection of the left main in two of the patients, while in the third one that of the right coronary artery. In the case of local dissection, angiography was sufficient to identify the true lumen, whereas in a dissection encompassing the whole of the coronary tree it was necessary to either find the coronary artery not involved in the dissection or to perform intravascular ultrasound imaging. After true lumen identification, the entry of dissection was stented with the optimal angiographic result.
