[Acetylsalicylic acid desensitization in the new era of percutaneous coronary intervention].

Dual antiplatelet therapy is essential in patients undergoing percutaneous coronary intervention with stent implantation. Hypersensitivity to acetylsalicylic acid (ASA) limits treatment options. Desensitization to ASA has classically been studied in patients with respiratory tract disease.

[Acute reperfusion therapy in elderly women with acute myocardial infarction with ST-segment elevation: efficacy in the reduction of their mortality].

Background And Objective: Elderly patients with acute coronary syndromes, particularly elderly women, suffer higher mortality and more morbidity than their younger counterparts. We try to document the outcome, treatment received and prognostic factors in this group.

Patients And Method: All data for ST-segment elevation myocardial infarction in women aged >/= 75 admitted to our hospital from 2002 to 2007 were retrospectively collected, including epidemiological and clinical variables, vascular complications, in-hospital outcome and middle-term follow-up.

Stent dislodgement during Szabo technique.

The implantation of a stent in ostial lesions with Szabo technique is a simple, ingenious and useful way of treating these complex lesions. But in some circumstances the manipulation of the stent added to a calcified vessel could finish with complications. We present a case of stent dislodgement during Szabo technique in an ostial lesion placed in left anterior descending artery.

Invasive treatment performed for acute myocardial infarction in a patient with immune thrombocytopenic purpura.

Acute myocardial infarction (AMI) is infrequent in patients with idiopathic thrombocytopenic purpura (ITP) so the best treatment is not well known. The next case shows a 37-year-old man with chronic ITP who suffered an anterior AMI, the platelet count at admission was 39,000 microL. He was treated successfully with primary percutaneous angioplasty under anticoagulation with unfractionated heparin and antiaggregation with clopidogrel and ASA.

[Drug eluting stents: long term results in clinical practice. Comparison between rapamycin and paclitaxel eluting stents].

Background And Objective: Drug eluting stents have demonstrated their superiority versus bare metal stents in the reduction of restenosis and major adverse cardiac events. Most studies do not identificate differences between rapamycin and paclitaxel eluting stent.

Patients And Method: Retrospective study.

[Coronary aneurysms not associated to stenosis of coronary arteries. Conservative treatment and evolution in six patients].

Coronary artery aneurysms are a relatively infrequent finding with an incidence of 1-2% per year. The most frequent cause is atherosclerosis and, in that case, they are always associated to stenosis of coronary arteries. We reviewed the coronary angiographic studies performed in the past seven years and we identified six patients that were admitted with an acute coronary syndrome, whose angiographic studies showed the presence of aneurysms in, at least, one of the coronary arteries.
