Background: Acute pulmonary embolism (APE) is often misdiagnosed as acute coronary syndrome because of the similarity of the presenting symptoms and of the electrocardiogram (ECG) manifestations. In APE, ST-segment elevation (STE) in leads V1 to V3 /V4 , mimicking anteroseptal myocardial infarction, is not a rare phenomenon. Negative T waves (NTW) in the precordial leads mimicking the "Wellens' syndrome" is an important ECG manifestation of APE. The evolution of these ECG changes-STE and NTW-in APE has not been thoroughly studied.
Methods: We present two patient cases with APE and their evolving serial ECGs to analyze the correlation between STE and NTW.
Results: NTW developed later than STE in these two patient cases.
Conclusions: NTW might represent a "postischemic" ECG pattern indicating a previous stage with transmural myocardial ischemia.

Background: The involvement of inflammation in the start and advancement of atherosclerotic plaques in acute coronary syndrome has been clarified. White blood cell count and its differential are key inflammatory markers in cardiovascular disease, with the neutrophil-to-lymphocyte ratio (NLR) emerging as a marker of inflammation and a predictor of mortality in patients with acute coronary syndrome. The study aims to investigate the utility of neutrophil to lymphocyte ratio and other complete blood count parameters as a risk stratification tool and independent predictor of Global Registry for Acute Coronary Events (GRACE) risk score in Non-ST segment elevation acute coronary syndrome (NSTE-ACS).

Acute myocardial infarction (AMI) is a leading cause of morbidity and mortality worldwide. Risk factors of mortality in patients with AMI have been widely investigated, identifying older age and heart failure as common contributors. This study aimed to determine risk factors and explore predictors associated with higher mortality among patients with AMI.

Background: Spontaneous reperfusion (SR) occurring before primary percutaneous coronary intervention (PPCI) can offer additional clinical benefits to patients with ST-segment elevation myocardial infarction (STEMI). The Platelet-to-White Blood Cell Ratio (PWR) has been recognized as a prognostic indicator in various diseases. We aimed to explore the relationship between PWR and SR in patients with STEMI undergoing PPCI.

Objectives: This study aimed to determine the distribution of coronary collaterals (CC) as per the Rentrop Collateral Score (RCS) among patients with ST-segment elevation myocardial infarction (STEMI) and its impact on in-hospital and 30-day mortality after primary percutaneous coronary intervention (PCI).
Methods: In this study, a selected sample of consecutive STEMI patients was assessed for the development of CC as per the RCS classification. An RCS grade of 2 or 3 was taken as the presence of CC with either partial or complete filling of the infarct-related artery (IRA).

Objective: To explore the prognosis and influencing factors of ST-segment elevation myocardial infarction (STEMI) due to late stent thrombosis (LST) and very late stent thrombosis (VLST).
Methods: Patients who underwent percutaneous coronary intervention (PCI) for STEMI caused by LST and VLST at Tianjin Chest Hospital from January 2016 to June 2021 were selected as the study subjects, and long-term follow-up was conducted. The baseline clinical features, laboratory examination indicators, echocardiography results, coronary angiography and intervention treatment characteristics, and antiplatelet treatment status of patients were collected.
