Cangrelor versus crushed ticagrelor in patients with acute myocardial infarction and cardiogenic shock: rationale and design of the randomised, double-blind DAPT-SHOCK-AMI trial.

Cardiogenic shock (CS) is a devastating and fatal complication of acute myocardial infarction (AMI). CS can affect the pharmacokinetics and pharmacodynamics of medications. The unique properties of cangrelor make it the optimal P2Y12 inhibitor for CS-AMI, in terms of both efficacy and safety.

Outcomes of patients with myocardial infarction and cardiogenic shock treated with culprit vessel-only versus multivessel primary PCI.

Introduction And Objectives: Multivessel primary percutaneous coronary intervention (pPCI) is still often used in patients with ST-elevation myocardial infarction (STEMI) and cardiogenic shock (CS). The study aimed to compare the characteristics and prognosis of patients with CS-STEMI and multivessel coronary disease (MVD) treated with culprit vessel-only pPCI or multivessel-pPCI during the initial procedure.

Material And Methods: From 2016 to 2020, 23,703 primary PCI patients with STEMI were included in a national all-comers registry of cardiovascular interventions.

Short-term risk of periprocedural stroke relative to radial vs. femoral access: systematic review, meta-analysis, study sequential analysis and meta-regression of 2,188,047 real-world cardiac catheterizations.

Objectives: To verify whether transradial (TRA) compared to transfemoral (TFA) cardiac catheterization reduces the risk of periprocedural stroke (PS).

Methods: We reviewed (CRD42021277918) published real-world cohorts reporting the incidence of PS within 3 days following diagnostic or interventional catheterization. Meta-analyses and meta-regressions of odds ratios (OR) performed using the DerSimonian and Laird method were checked for publication bias (Egger test) and adjusted for false-positive results (study sequential analysis SSA).

Surgical treatment of primary cardiac tumors: 20-year single center experience.

Introduction: Primary cardiac tumors are a rare condition presenting with a variety of symptoms. The outcomes of their surgical treatment in the modern era from central Europe have not been recently reported.

Aim: To evaluate the short- and long-term outcomes of the cardiac tumor operations at our department throughout the last 20 years.

Accession Site Does Not Influence the Risk of Stroke after Diagnostic Coronary Angiography or Intervention: Results from a Large Prospective Registry.

Introduction: Periprocedural stroke represents a rare but serious complication of cardiac catheterization. Pooled data from randomized trials evaluating the risk of stroke following cardiac catheterization via transradial versus transfemoral access showed no difference. On the other hand, a significant difference in stroke rates favoring transradial access was found in a recent meta-analysis of observational studies.

Cardiac resynchronisation therapy optimisation of interventricular delay by the systolic dyssynchrony index: A comparative, randomised, 12-month follow-up study.

Background: The aim of our study was to compare the effect of interventricular (VV) delay optimisation in CRT recipients on the basis of systolic dyssynchrony index (SDI) derived from the three-dimensional echocardiography (3DE) versus QRS width assessment on left ventricle volume reduction at the 12-month follow-up.

Methods: We included 63 patients with recently implanted CRT in this randomised, open-label trial. Patients were randomised to VV delay optimisation according to QRS complex width measurement in group 1 (n = 31) to obtain the narrowest QRS complex and SDI in group 2 (n = 32) to achieve its lowest possible value.

Heart failure is the strongest predictor of acute kidney injury in patients undergoing primary percutaneous coronary intervention for ST-elevation myocardial infarction.

Background: ST elevation myocardial infarction (STEMI) patients treated by primary percutaneous coronary intervention (PCI) are at higher risk of acute kidney injury (AKI) than patients undergoing PCI in stable clinical conditions. This fact suggests that mechanisms other than contrast nephrotoxicity are involved.

Aim: To evaluate the incidence, risk factors, and consequences of AKI in patients undergoing primary PCI for STEMI in current daily practice.

Prevention of contrast-induced acute kidney injury by theophylline in elderly patients with chronic kidney disease.

Although the optimal strategy for preventing contrast-induced acute kidney injury (CI-AKI) has not yet been established, the current strategy focuses on adequate periprocedural hydration, the use of a low amount of low or iso-osmolar contrast medium, and the application of adjunctive therapies, including hemofiltration, hemodialysis and drugs. Previous trials and meta-analyses concerning the use of the adenosine antagonist theophylline have revealed contradictory results. We sought to evaluate the effect of theophylline in CI-AKI prevention in well-hydrated elderly patients with chronic kidney disease.

Unintended stent extraction from a coronary artery during bifurcation coronary angioplasty.

We report an elective angioplasty of a left circumflex artery (LCx) bifurcation lesion treated by provisional stenting. With a "jailed" wire in the first obtuse marginal, we deployed a 3.0 x 28 mm drug-eluting stent into the main branch.

Out-of-hospital cardiac arrests in patients with acute ST elevation myocardial infarctions in the East Bohemian region over the period 2002-2004.

Background: Early reperfusion by direct percutaneous coronary intervention (PCI) in patients with ST segment elevation acute myocardial infarctions (STEMI) with an out-of-hospital cardiac arrest (OHCA) reduces hospital and longterm mortality.

Aims: Evaluating the significance of direct PCI for the short-term (discharge from acute hospitalization) and 1-year survival in patients with acute STEMI after OHCA.

Methods: In this prospective study, from April 1, 2002 up to August 31, 2004, a total of 26 hospitalized individuals (22 men, 4 women, aged 35-79 years, median 58.
