AI Article Synopsis
- The study examined factors affecting 30-day survival rates after urgent coronary interventions for patients experiencing life-threatening heart rhythm issues linked to heart attacks.
- 55 patients were analyzed, grouped by whether they survived beyond 30 days (survival group) or died within that timeframe (death group), focusing on their characteristics and medical procedures.
- Key findings revealed that immediate cardiopulmonary resuscitation (CPR) and having single-vessel coronary artery disease significantly predicted better survival outcomes, while absence of diabetes and low arterial lactate also correlated positively with survival.
Article Abstract
Background: Little has been reported on the predictors of 30-day survival after emergent percutaneous coronary intervention (PCI) following life-threatening ventricular tachyarrhythmias associated with acute myocardial infarction (AMI).
Methods: We analyzed 55 consecutive patients who underwent an emergent PCI after ventricular fibrillation (VF) or pulseless ventricular tachycardia (VT) complicating AMI between September 2014 and March 2023 in our hospital. These patients were categorized into two groups: survival group (S group) who survived >30 days after the emergent PCI and death group (D group) who died by 30 days after the emergent PCI. We compared the patient characteristics, coronary angiographic findings, and PCI procedures between the two groups.
Results: S group consisted of 40 patients. In the univariate analysis, absence of diabetes mellitus, presence of immediate cardiopulmonary resuscitation (CPR), low arterial lactate, and single-vessel coronary artery disease (CAD) were associated with 30-day survival after the emergent PCI (P = 0.048, P < 0.001, P = 0.009, and P = 0.003, respectively). In the multivariate analysis, presence of immediate CPR and single-vessel CAD were independently associated with 30-day survival after the emergent PCI (P = 0.023 and P = 0.032, respectively).
Conclusions: Immediate CPR and single-vessel CAD were significant predictors of 30-day survival after the emergent PCI following VF or pulseless VT complicating AMI. Absence of diabetes mellitus and low arterial lactate were associated with 30-day survival in the univariate analysis.

Coronary heart disease and type 2 diabetes mellitus (T2DM) often co-occur, presenting substantial health risks, particularly following acute myocardial infarction (AMI). While percutaneous coronary intervention (PCI) is a prevalent treatment, complications such as microvascular dysfunction may lead to heart failure, necessitating additional therapies. This editorial examines the emerging roles of sacubitril/valsartan and sodium-glucose co-transporter 2 inhibitors in managing post-PCI.

Background: Concurrent ST-elevation myocardial infarction (STEMI) and acute ischemic stroke (AIS) are extremely rare, and their management remains perplexing due to the absence of high-quality evidence and limited resources. For the first time, we report a rare, preventable, and suboptimally managed case of concurrent AIS and STEMI in a patient with non-Hodgkin lymphoma (NHL) who received cyclophosphamide, doxorubicin, vincristine, and prednisolone (CHOP) chemotherapy.
Case Presentation: A 59-year-old postmenopausal woman of African origin with a background history of type 2 diabetes mellitus presented to the Jakaya Kikwete Cardiac Institute with sudden onset of left-sided weakness and typical ischemic chest pain for 3 days.

Introduction: The optimal revascularization strategy for patients with myocardial infarction (MI) and multivessel coronary artery disease (CAD) remains an area of research and debate. Fractional flow reserve (FFR)-guided complete revascularization (CR) by percutaneous coronary intervention (PCI) has emerged as an alternative to traditional culprit-only PCI.
Objective: To investigate the outcomes of FFR-guided CR versus culprit-only PCI in patients with MI and multivessel CAD.

Background: Pancreatic ductal adenocarcinoma (PDAC) requires innovative therapeutic strategies to counteract its progression and metastatic potential. Since the majority of patients are diagnosed with advanced metastatic disease, treatment strategies targeting not only the primary tumor but also metastatic lesions are needed. Tumor-Associated Macrophages (TAMs) have emerged as central players, significantly influencing PDAC progression and metastasis.

Background: Drug-coated balloons (DCB) are emerging as an alternative to permanent implants for managing de novo coronary artery disease, particularly in small vessels (SVD). This sub-analysis of the PICCOLETO II study aimed to compare the performance of DCB and DES in terms of Murray's law-based quantitative flow ratio (μFR) changes between baseline, post-percutaneous coronary intervention (PCI), and follow-up.
Methods: Patients with a clinical indication for PCI were assigned to receive either Xience DES or Elutax SV/Emperor DCB.
