Unlabelled: The study compared the efficiency of percutaneous coronary interventions (PCI) into infarction-related coronary artery (IRCA) in high-risk patients with acute myocardial infarction (AMI), that were fulfilled 12-24 hours since the pain syndrome onset or during recurrent ischemic episodes 3 days after successful thrombolysis. In the first group (68 patients) invasive restoration of blood flow was fulfilled in 3 days (at average 48 hours) after AMI onset due to recurrent ischemia. In the second group (56 patients) IRCA recanalization was fulfilled in 12-24 hours (at average 20 hours) since pain syndrome onset due to clinical signs of unfavorable outcome high risk. IRCA recanalization was successful in 91% and 97% of cases in the first and second groups, respectively. In all cases injection of contrast media Ultravist 370 was diagnostically significant and visualized coronary arteries free of adverse events. In control group (conservative treatment) IRCA occlusion or subtotal stenosis was diagnosed in 18% and 39% of cases, respectively; stenosis >75% and <75% - in 27% and 16%, respectively.
Conclusion: in high-risk patients with AMI percutaneous coronary interventions into IRCA can be effective 12-24 hours after successful thrombolytic therapy.

Background: Geographic stent-ostium mismatch is an important predictor of target lesion failure after percutaneous coronary intervention of an aorto-ostial right coronary artery lesion. Optimal visualization of the aorto-ostial plane is crucial for precise stent implantation at the level of the ostium. This study investigates whether preprocedural 3-dimensional computed tomography (3DCT), with determination of the optimal viewing angle, would allow for more precise stent implantation and reduce procedure time, contrast, and radiation dose.

Background: Previous studies suggest similar cardiovascular (CV) benefits for either percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) in patients with left main coronary artery disease (LMCAD). However, limited data exist on the influence of prior cerebrovascular disease (CEVD). Thus, we aim to compare the CV outcomes in patients with LMCAD and prior CEVD, undergoing either PCI or CABG.

Background: The pharmacoinvasive (PhI) strategy is the standard-of-care for ST-elevation myocardial infarction (STEMI) patients when primary percutaneous coronary intervention (pPCI) is unfeasible. Optimal timing for post-fibrinolytic PCI (lysis-PCI) remains elusive. Therefore, this study aimed to assess the clinical and economic impacts of early vs.

Background: Cardiovascular diseases and cancer are leading causes of morbidity and mortality. Patients with malignancies are at increased risk for cardiovascular complications including acute coronary syndromes, chemotherapy or radiation therapy related complications and cardiac metastasis.
Case Summary: We present a case of a 47-year-old female with metastatic cancer on immunotherapy presented with anterior ST elevation myocardial infarction followed by emergent percutaneous coronary intervention in the left anterior descending artery.
Parsimonious versus extensive bleeding score: can we simplify risk stratification after percutaneous coronary intervention and reduce bleeding events by de-escalation of the antiplatelet strategy?

Background And Aims: Due to the multitude of risk factors outlined in the guidelines, personalised dual antiplatelet therapy (DAPT) guidance after percutaneous coronary intervention (PCI) is complex. A simplified method was created to facilitate the use of risk stratification. We aimed to compare the predictive and prognostic value of the 'Zuidoost Nederland Hart Registratie' (ZON-HR) classification for bleeding risk with the PREdicting bleeding Complications In patients undergoing Stent implantation and subsEquent DAPT (PRECISE-DAPT) score and to determine the effect of ticagrelor monotherapy versus DAPT in patients with or without high bleeding risk (HBR).
