Introduction: Despite high rates of morbidity and mortality in patients with contrast-induced nephropathy (CIN), there is no consensus regarding prevention of this well-known complication of contrast media use. One agent that has been widely used in this regard is N-acetyl cysteine (NAC). Nevertheless, its efficacy is still controversial.

- Acute pulmonary embolism (PE) poses serious risks, and this study explored how certain cardiac biomarkers are linked to patient outcomes.
- Out of 86 patients with confirmed PE, 59 were included, and levels of several biomarkers, including NT-proBNP, were measured; a key finding was that higher NT-proBNP levels were associated with worse short-term outcomes.
- The study suggests that monitoring NT-proBNP levels could enhance the prediction and management of outcomes for patients with non-high-risk PE, as elevated levels were also correlated with long-term mortality.
Article Synopsis
- The study assessed the success rate of percutaneous coronary intervention (PCI) for chronic total occlusion and identified factors influencing both technical success and one-year major adverse cardiac events (MACE).
- A total of 269 patients were analyzed, revealing an 82.2% procedural success rate and a low one-year MACE occurrence of 4.8%, primarily from target-vessel revascularization.
- Key predictors for technical failure included lesion location, presence of multivessel disease, and specific clinical indicators, highlighting PCI's overall safety and effectiveness for this condition.
Background: The optimal strategy in percutaneous coronary intervention (PCI) for coronary artery bifurcation lesions has yet to be agreed upon. We compared a strategy for stenting the main vessel to provide a complete perfusion flow in the side branch, namely thrombolysis in myocardial infarction (TIMI) - III, with a strategy for intervention in both the main vessel and the side branch (MV + SB).
Methods: This retrospective study utilized data on 258 consecutive patients with bifurcation lesions scheduled for PCI at Tehran Heart Center between March 2003 and March 2008.
Effectiveness of Two-Year versus One-Year Use of Dual Antiplatelet Therapy in Reducing the Risk of Very Late Stent Thrombosis after Drug-Eluting Stent Implantation.

Background: Impact of 12 months' versus 24 months' use of dual antiplatelet therapy on the prevalence of stent thrombosis in patients undergoing percutaneous coronary intervention (PCI) with the drug-eluting stent (DES) is not clear. As a result, duration of dual antiplatelet therapy is still under debate among interventionists.
Methods: From March 2007 until August 2008, all consecutive patients with successful PCI who received at least one DES and were treated with dual antiplatelet therapy (Clopidogrel + Aspirin) were included.
Background: The current study aims to identify demographic, clinical characteristics, echocardiographic and/or mitral valve morphological parameters that may predict the successful result of percutaneous transvenous mitral commissurotomy (PTMC).
Methods: The medical records of 196 patients (48 males, mean age: 42.7 ± 11.
