AbstractIn percutaneous coronary intervention (PCI) to the culprit lesion of acute myocardial infarction (AMI), unsuccessful guidewire crossing causes immediate poor outcomes. It is important to determine the factors associated with unsuccessful guidewire crossing in AMI lesions. The purpose of this study was to find factors associated with difficulty in crossing the culprit lesion of AMI. We defined the difficult group when the guidewire used to cross the culprit lesion was a polymer jacket type guidewire or a stiff guidewire. We included 937 patients, and divided those into the non-difficult group (n = 876) and the difficult group (n = 61). Proximal reference diameter was significantly smaller in the difficult group than in the non-difficult group (p < 0.001), and degree of calcification was severer in the difficult group than in the non-difficult group (p < 0.001). In the multivariate stepwise logistic regression analysis, proximal reference diameter [odds ratio (OR) 0.313, 95% confidence interval (CI) 0.185–0.529, p < 0.001)], previous PCI (OR 3.065, 95% CI 1.612–5.830, p = 0.001), moderate-severe calcification (OR 4.322, 95% CI 2.354–7.935, p < 0.001), blunt type obstruction (OR 12.646, 95% CI 6.805–23.503, p < 0.001), and the presence of collateral to the culprit lesion (OR 2.110, 95% CI 1.145–3.888, p = 0.017) were significantly associated with difficulty in crossing the culprit lesion. In conclusion, previous PCI, calcification, blunt type obstruction, and the presence of collateral were associated with difficulty in crossing the culprit lesion, whereas proximal reference diameter was inversely associated with difficulty. Our study provides a reference to recognize the difficulty in crossing the culprit lesions of AMI for PCI operators, especially junior operators.

Background: Early revascularisation of the culprit lesion is the therapeutic cornerstone in cardiogenic shock complicating acute myocardial infarction. The optimal management of additional non-culprit lesions is unclear. This systematic review and meta-analysis aims to summarise current evidence on the comparison of immediate multivessel percutaneous coronary intervention (MV-PCI) or culprit lesion only PCI with possible staged revascularisation (C-PCI) in patients with cardiogenic shock complicating acute myocardial infarction. Methods: Medical literature databases were screened to identify analyses comparing MV-PCI with C-PCI in patients with cardiogenic shock complicating acute myocardial infarction and multivessel coronary artery disease. In absence of randomised trials, 10 cohort studies were included in the current meta-analysis. The primary outcome of short-term mortality was assessed at hospital discharge or 30 days after hospital admission. Secondary outcomes were long-term mortality as well as myocardial re-infarction, stroke, acute renal failure, and bleeding at short-term follow-up. Results: Of 6051 patients, 1194 (19.7%) received MV-PCI and 4857 (80.3%) C-PCI. Short-term mortality was 37.5% in patients undergoing MV-PCI compared with 28.8% in C-PCI patients (risk ratio 1.26, 95% confidence interval 1.12–1.41, p=0.001). Long-term mortality ( p=0.77), myocardial re-infarction ( p=0.77), stroke ( p=0.12), acute renal failure ( p=0.17) and bleeding ( p=0.53) did not differ significantly between the two revascularisation groups. Conclusions: Results of this first meta-analysis on the interventional management of patients with cardiogenic shock complicating acute myocardial infarction and multivessel coronary artery disease do not support MV-PCI over C-PCI. However, possible treatment selection bias in the individual studies must be taken into account.

Background: Post-acute myocardial infarction (post-AMI) infection is an infrequent but important and serious complication in patients with ST-segment elevation myocardial infarction (STEMI) treated with percutaneous coronary intervention (PCI). Predicting its occurrence is essential for future prevention. However, little is known about the prediction of post-AMI infection in such patients to date. This study aims to develop and validate a new risk score based on risk factors for early prediction of infection in STEMI patients undergoing PCI.Methods: This prospective, multi-center and observational study assesses the predictive value of risk score for post-AMI infection among a cohort of patients hospitalized due to STEMI. The STEMI patients undergoing PCI enrolled between January 1st 2010 and May 31st 2016 were served as a development cohort while those enrolled from June 1st 2016 to May 31st 2018 were served as validation cohort. The primary endpoint was post-AMI infection during hospitalization, defined as infection requiring antibiotics (reflecting the clinical influence of infection compatible with the necessity for additional treatment), and all-cause death and major adverse cardiovascular events (MACE) including all-cause death, recurrent myocardial infarction, target vessel revascularization, and stroke were considered as secondary endpoints. The risk score model based on risk factors was established using stepwise logistic regression, and will be validated in other centers and external patients with non-ST-elevation acute coronary syndrome (NSTE-ACS).Results: This study will provide evidence on prognostic property, reliability of scoring, comparative performance, and suitability of the novel model for screening purpose in order to be recommended for clinical practice.Discussion: Our study is designed to develop and validate a clinical risk score for predicting infection in participants with STEMI who have undergone PCI. This simple tool may therefore improve evaluation of post-AMI infection and enhance future researches into the best practices to prevent or reduce infection in such patients.Clinical Trial Registration:www.chictr.org.cn, identifier: ChiCTR1900028278.
