Objective: The aim: To investigate long-term effects of primary percutaneous coronary interventions (pPCI) in patients with STEMI basing on the prevalence of clinically relevant endpoints.
Patients And Methods: Materials and methods: Totally 200 patients with STEMI hospitalized within a period of "therapeutic window" for revascularization were included into the study. 100 patients who additionally to pPCI underwent manual thromboaspiration entered the main group. The comparison group consisted of 100 patients who underwent standard pPCI.
Results: Results: Six months after the pPCI, the incidence of either major adverse cardiac events and the combined endpoint did not differ in the main and comparative groups (11.8% vs. 12.5%, p = 0.888 and 18.2% vs. 20.8%, p = 0.658, respectively). There were no significant differences in these endpoints taken separately. In twelve months after procedure, also there were no significant differences between the groups. However, a tendency toward lower incidence of chest pain was observed in the main group (p = 0.08) during this period that was lost in 24 months after pPCI. None of these techniques demonstrated significant advantages during the whole duration of the follow-up period.
Conclusion: Conclusions: The addition of manual thromboaspiration to the standard pPCI in patients with STEMI and severe thrombosis of the culprit artery did not significantly influence the prognosis.

Background: Acute myocardial infarction (AMI), particularly ST-segment elevation myocardial infarction (STEMI), significantly impacts global health, exacerbated by risk factors such as diabetes mellitus (DM). While the Gensini score effectively quantifies coronary artery lesions, its correlation with fasting blood glucose (FBG) levels, particularly in a non-linear fashion, has not been thoroughly explored in STEMI patients.
Methods: This study analyzed data from 464 STEMI patients treated with percutaneous coronary intervention at the First People's Hospital of Taizhou City, Zhejiang Province, China, from January 2010 to October 2014.

Acute coronary syndrome (ACS) is one of the most common leading global causes of mortality, encompassing ST-segment elevation myocardial infarction (STEMI), non-ST-segment elevation myocardial infarction (NSTEMI), and unstable angina (UA). Percutaneous coronary intervention (PCI) has become a pivotal therapeutic approach for ACS, underscoring the importance of anticoagulation strategies. Among the commonly employed anticoagulants in PCI, heparin and bivalirudin take precedence, with heparin serving as the archetypal choice.

Background: Anomalous origin of the left coronary artery (LCA) from the pulmonary artery (PA) (ALCAPA) is a rare congenital abnormality. We present a case of an ALCAPA in a 25-year-old man.
Case Summary: A 25-year-old male with no past medical history was admitted to our intensive cardiac care unit after sudden cardiac arrest due to ventricular fibrillation and suspected acute coronary syndrome.

Coronary artery spasm (CAS) is a key contributor to the pathogenesis of acute ST-segment elevation myocardial infarction (STEMI). While smoking is recognized as a major risk factor for CAS, the relationship between cumulative cigarette consumption and infarction-related CAS across different age groups in STEMI patients remains unclear. This study aimed to investigate the correlation between cumulative cigarette consumption and infarction-related CAS across different age groups through a retrospective analysis.

Aims: Timely assessment of abnormal microvascular perfusion (MVP) may improve prognosis in patients with ST-segment elevation myocardial infarction (STEMI). This study aimed to determine the clinical implications of contrast-flow quantitative flow ratio (cQFR) in evaluating abnormal MVP and subsequent outcomes among STEMI patients after successful primary percutaneous coronary intervention (PPCI).
Methods: The study population consisted of 2 independent cohorts.
