Dose the fractured guide wire should be removed during or after percutaneous coronary interventions? In case when the patients have unstable hemodynamic status the fractured guide wire should be removed with percutaneous or surgical method. Antiplatelet drug administration should be considered after procedure to prevention of the coronary artery thrombosis.

Background: Cardiovascular diseases are global problems. They are causes of death in about 43% of people worldwide and may become the most widespread reason of death by 2020. The prognosis is directly dependent to immediate diagnosis and on time treatment. Introduction of new biochemical markers as the early diagnosis of complications after coronary revascularization is very important in this p...

to study the resistance to standard dosage of clopidogrel among iranian patients following percutaneous coronary intervention measured by platelet aggregation test.patients undergoing percutaneous coronary intervention in imam hussein medical center, tehran, iran, who were under treatment with aspirin, but had no history of clopidogrel usage, entered the study. patients received standard dosage...

We describe a case of Prinzmetal’s angina that is refractory to medical therapy but responded fully after percutaneous coronary intervention. This case shows that there is a role for percutaneous coronary intervention in refractory variant angina as long as a culprit lesion within the vasospastic segment can be identified.

There is strong relationship exist between obesity and cardiovascular disease including coronary artery disease (CAD). However, better outcomes noted in obese patients undergoing percutaneous cardiovascular interventions for CAD, a phenomenon known as the obesity paradox. In this review, we performed extensive search for obesity paradox in obese patients undergoing percutaneous coronary interve...

Coronary artery perforation as a result of percutaneous coronary intervention is a rare complication which may result in cardiac tamponade, myocardial infarction and death. Perforation of a saphenous vein graft is unusual and generally requires surgical intervention. We describe a novel percutaneous approach that facilitated the successful management of a potentially catastrophic saphenous vein...

Spontaneous coronary artery dissection is a rare cause of acute coronary events or sudden cardiac death. The clinical presentation is highly variable and prognosis varies widely, depending mainly on how rapidly it is diagnosed. Prompt treatment is also essential, and includes medical management, percutaneous coronary intervention and surgical revascularization. We describe the case of a young w...

The aim of this randomized prospective study was to evaluate the quality life (QoL) using "Seattle Angina Questionnaire" (SAQ) in patients with chronic total occlusion (CTO) coronary arteries treated either percutaneous intervention (PCI) or optimal medical therapy (OMT), only OMT.
