Insights
Direct coronary stenting (DS) showed comparable in-hospital outcomes to stenting after predilation (PD) in ST-elevation myocardial infarction (STEMI) patients. This study compared major adverse cardiac events (MACE) between the two primary PCI strategies.
Area of Science:
- Cardiology
- Interventional Cardiology
- Clinical Research
Background:
- ST-elevation myocardial infarction (STEMI) is a critical condition requiring timely reperfusion therapy.
- Primary percutaneous coronary intervention (PCI) is the preferred reperfusion strategy for STEMI.
- The optimal stenting technique, direct stenting (DS) versus stenting after predilation (PD), remains an area of investigation.
Purpose of the Study:
- To compare in-hospital outcomes of DS versus PD in STEMI patients undergoing primary PCI.
- To evaluate major adverse cardiac events (MACE), including death, myocardial infarction, and stent thrombosis.
- To identify predictors of the no-reflow phenomenon in this patient cohort.
Main Methods:
- Retrospective analysis of 1103 STEMI patients undergoing primary PCI from 2006 to 2014.
- Comparison of clinical and angiographic characteristics between DS (n=563) and PD (n=540) groups.
- Assessment of in-hospital MACE and analysis of no-reflow predictors.
Main Results:
- No significant difference in MACE was observed between DS and PD groups.
- Patients in the DS group were younger (57.9 vs 60 years) and had less chronic kidney disease (5.2% vs 8.4%).
- The DS group more frequently received prehospital thrombolysis (25% vs 11.9%).
Conclusions:
- Direct stenting is a safe and effective strategy for STEMI patients undergoing primary PCI.
- The choice between DS and PD may depend on patient characteristics and procedural factors.
- Further research is warranted to explore long-term outcomes and specific patient subgroups.
Aim:
To study was to assess in-hospital outcomes of direct coronary stenting (DS) compared with stenting after predilation (PD) in patients with ST-elevation myocardial infarction (STEMI).
Material And Methods:
Data were collected from all patients (n=1103) with STEMI subjected to primary PCI in Tyumen cardiology center from 2006 to 2014. The clinical and angiographic characteristics, in-hospital outcomes, as well as predictors of no-reflow phenomenon were analyzed. The composite of in-hospital death, myocardial infarction (MI) and stent thrombosis were defined as major adverse cardiac events (MACE).
Results:
Altogether 563 patients (51 %) underwent DS, and in 540 (49 %) stents were implanted after PD. Patients in DS group compared with those in PD group were younger (57.9±10.9 vs 60±11.5 years; p=0.001), less often had chronic kidney disease (5.2 vs 8.4 %; р=0.034), more often recieved prehospital thrombolysis (25 vs 11.9 %; p.

Freezing Point Depression and Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...

Once about 20-40 ribonucleotides have been joined together by RNA polymerase, a group of enzymes adds a “cap” to the 5’ end of the growing transcript. In this process, a 5’ phosphate is replaced by modified guanosine that has a methyl group attached to it (7-Methyl...
