Two Approaches to Triple Antithrombotic Therapy in Patients with Acute Coronary Syndrome and Non-Valvular Atrial Fibrillation Treated with Percutaneous Coronary Intervention: Which Is More Efficient and Safer?

INTRODUCTION: Patients with acute coronary syndrome (ACS) and atrial fibrillation (AF) treated with percutaneous coronary intervention (PCI) are at high risk of bleeding and thromboembolic events. Thus, optimal treatment strategies in this challenging subset have been controversial. Herein, we aim to investigate different triple antithrombotic treatment (TAT) strategies in patients with ACS and AF after PCI. METHODS: This was a retrospective, single-center study based on all consecutive patients with the diagnosis of ACS and AF treated with vitamin K antagonists (VKA) or non-vitamin K antagonist oral anticoagulants (NOAC) plus dual antiplatelet therapy using a P2Y12 inhibitor (clopidogrel) and aspirin (for 1 to 3 months) and observed for 12 months for major adverse cardiac events (MACE) and major or clinically relevant non-major bleeding incidents. RESULTS: MACE occurred in 26.6% of patients treated with the VKA and 30.9% with NOAC (p = 0.659). Bleeding occurred in 7.8% of patients treated with VKA and 7.4% with NOAC (ns). CONCLUSIONS: Among patients with ACS and AF who had undergone PCI, there was no significant difference in the risk of bleeding and ischemic events among those who received TAT with NOAC and VKA.

Vitamin B1 Deficiency and Perimyocarditis Fulminans: A Case Study of Shoshin Syndrome in a Woman Following an Unbalanced Dietary Pattern Followed by a Literature Review.

(1) Background: vitamin B1 level depletion, known as a beriberi syndrome, can lead to severe cardiovascular complications, from which perimyocarditis fulminans is one of the most severe. (2) Methods: this is a retrospective case study that includes an adult patient with clinical presentations of acute heart failure (HF) symptoms following perimyocarditis on the grounds of thiamine deficiency. (3) Results: A 49-year-old woman presented with acute HF symptoms due to perimyocarditis. The patient suddenly developed refractory cardiogenic shock with metabolic acidosis requiring maximal medical management, including an intra-aortic balloon pump and extracorporeal membrane oxygenation. Due to additional peripheral polyneuropathy, beriberi disease was suspected after excluding other possible causes of the patient's condition. After administration of vitamin B1, clinical improvement in the patient's condition and the resolution of metabolic abnormalities were observed, which ultimately confirmed the diagnosis of Shoshin syndrome caused by the implementation of a gluten-free diet without indications for its adherence. (4) Conclusions: Fulminant beriberi disease, although considered rare, is a life-threatening condition and should always be included in the differential diagnosis of critically ill patients, notably those with malnutrition. An unbalanced diet can be detrimental and have severe consequences, i.e., perimyocarditis fulminans. However, treatment with thiamine can significantly improve the patient's cardiac function and restore hemodynamic and metabolic parameters.

Cardiovascular events in patients with familial hypercholesterolemia and hyperlipoproteinaemia (a): Indications for lipoprotein apheresis in Poland.

BACKGROUND: Lipoprotein apheresis (LA) is a safe method of reducing atherogenic lipoproteins and improving cardiovascular (CV) outcomes. We aimed to assess the reductions in low-density lipoprotein cholesterol (LDL-C) and lipoprotein (a) [Lp(a)] levels in patients undergoing regular LA therapy and to evaluate its influence on the incidence rate of adverse cardiac and vascular events (ACVE) and major adverse cardiac events (MACE). METHODS: A longitudinal study in Poland evaluated the prospective and retrospective observational data of 23 patients with hyperlipoproteinaemia (a) [hyper-Lp(a)] and familial hypercholesterolemia (FH), undergoing 1014 LA sessions between 2013 and 2020. Their pre- and post-apheresis LDL-C and Lp(a) levels were assessed to calculate the acute percent reductions. The time period used to evaluate annual rates of ACVE and MACE before and after initiation of LA was matched in each patient. RESULTS: The pre-apheresis LDL-C and Lp(a) concentrations were 155 (107-228) (mg/dL) (median and interquartile range) and 0.56 (0.14-1.37) (g/L), respectively. LA therapy resulted in a reduction of LDL-C to 50 (30-73.5) (mg/dL) and of Lp(a) to 0.13 (0.05-0.34) (g/L), representing a percent reduction of 70.0% and 72.7% for LDL-C and Lp(a), respectively. We found a significant reduction in the annual rate of ACVE (0.365[0.0-0.585] vs (0.0[0.0-0.265]; P = .047) and MACE (0.365[0.0-0.585] vs 0.0[0.0-0.265]; P = .031). CONCLUSIONS: The findings of our study indicate that LA treatment in patients with hyperlipoproteinaemia (a) and FH on maximally tolerated lipid lowering therapies leads to a substantial reduction in LDL-C and Lp(a) concentrations and lowers CV event rates in Polish patients.

Heart failure as the first manifestation of severe non-cardiac disease.

Heart failure in patients with rheumatoid arthritis (RA) caused by secondary amyloidosis is now extremely rare. A CASE REPORT: A 42 year old female patient with rheumatoid arthritis was admitted to our cardiology unit to diagnose and find the cause of her heart failure. Echocardiography showed marked diastolic dysfunction, hypertrophic cardiomyopathy and global longitudinal strain characteristic for cardiac amyloidosis. However, the suspicion of secondary amyloidosis related to her RA was excluded based on negative results of anti-SAA test. Cardiac MRI showed typical changes for cardiac amyloidosis in agreement with the primary echocardiography. Measurement of serum free light chain ratio revealed pattern typical for light chain amyloidosis secondary to multiple myoloma, confirmed by plasmocytosis on bone marrow biopsy and histopathology of salivary gland. CONCLUSIONS: In patients with cardiac amyloidosis, despite strong clinical suggestions, the definite diagnosis should be always established because it may allow to implement effective treatment.

New-generation drug eluting stent vs. bare metal stent in saphenous vein graft - 1 year outcomes by a propensity score ascertainment (SVG Baltic Registry).

BACKGROUND: Data regarding the efficacy of the percutaneous coronary intervention (PCI) with new-designed drug-eluting stent (new-DES) vs. bare metal stent (BMS) of saphenous vein grafts (SVG) stenosis is scarce. The primary objective was to compare one-year clinical outcomes of PCI in stenosis of SVG using new-DES vs. BMS in a real-world population. METHODS AND RESULTS: We carried out a multi-center registry comparing new-DES with BMS in all consecutive patients undergoing PCI of SVG. The primary composite endpoint was major adverse cardiac and cerebrovascular events (MACCE) at 1 year. This observation included 792 consecutive patients (mean age 69 ±â€¯8.9y), treated with either new-DES (n = 379, 47.9%) or BMS (n = 413, 52.1%). Among patients treated with new-DES compared with BMS, there was a lower risk of MACCE (21.4% vs. 28.3%, HR = 0.69, 95% CI 0.50-0.95, p = 0.025) as well as myocardial infarction (MI) (6.3% vs. 12.1%; HR 0.49, 95% CI 0.30-0.82, p = 0.005) at 1 year. After propensity score adjustment, the similar, significant reduction in MACCE and MI was observed in favor of new-DES (HR 0.66, 95% CI 0.46-0.96, p = 0.030; and HR 0.53, 95% CI 0.31-0.92, p = 0.020, respectively). CONCLUSION: In patients undergoing PCI of SVG, the use of new-DES is associated with a reduced 1-year rate of MACCE and MI compared to BMS.

Long-term lipoprotein apheresis in the treatment of severe familial hypercholesterolemia refractory to high intensity statin therapy: Three year experience at a lipoprotein apheresis centre.

BACKGROUND: Severe familial hypercholesterolemia (FH) individuals, refractory to conventional lipidlowering medications are at exceptionally high risk of cardiovascular events. The established therapeutic option of last choice is lipoprotein apheresis (LA). Herein, it was sought to investigate the clinical usefulness of LA in a highly selected group of severe heterozygous FH (HeFH), as recently described by the International Atherosclerosis Society (IAS), for their efficacy in lipid reduction and safety. METHODS: Efficacy and safety of LA were investigated in 318 sessions of 7 severe HeFH females with cardiovascular disease, over a mean period of 26.9 ± 6.5 months. Relative reduction of low density lipoprotein cholesterol (LDL-C) ≥ 60%, clinical complications and vascular access problems were evaluated and compared between the direct adsorption of lipoproteins (DALI) and lipoprotein filtration (Membrane Filtration Optimized Novel Extracorporeal Treatment [MONET]). Additionally, lipoprotein (a) [Lp(a)], total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), triglycerides (TG) and fibrinogen concentrations were investigated. RESULTS: The relative reduction of LDL-C, TC, TG and Lp(a) were 69.4 ± 12.9%, 59.7 ± 9.1, 51.5 ± ± 14.2% and 71.3 ± 14.4%, respectively. A similar efficacy was found in both systems in LDL-C removal. DALI system led to larger depletions of Lp(a) (80.0 [76-83]% vs. 73.0 [64.7-78.8]%; p < 0.001). The frequency of clinical side effects and vascular access problems were low (8.5%). CONCLUSIONS: Long-term LA in severe HeFH individuals is safe and efficiently reduces LDL-C and Lp(a). Higher efficacy of the DALI system than MONET in Lp(a) removal may indicate the need for individualized application of the LA system in severe HeFH individuals.
