Percutaneous mechanical thrombectomy in patients with high-risk pulmonary embolism and contraindications for thrombolytic therapy.

Background High-risk pulmonary embolism is associated with a high early mortality rate. We report our experience with percutaneous mechanical thrombectomy in patients with high-risk pulmonary embolism and contraindications for thrombolytic therapy. Patients and methods This was a retrospective analysis of consecutive patients with high-risk pulmonary embolism and contraindications to thrombolytic therapy.

Impact of time from symptom onset to drug administration on outcome in patients undergoing glycoprotein IIb-IIIa facilitated primary angioplasty (from the EGYPT cooperation).

Contrasting data have been so far reported on facilitation with glycoprotein IIb-IIIa inhibitors (GpIIbIIIa) in patients who underwent primary percutaneous coronary intervention. However, it has been demonstrated a time-dependent composition of coronary thrombus in ST-segment elevation myocardial infarction, with more platelets in the first hours. Subsequently, the benefits of early administration of GpIIbIIIa may be affected by the time from symptoms onset to GpIIbIIIa, that therefore is the aim of this study.

Impact of hypertension on distal embolization, myocardial perfusion, and mortality in patients with ST segment elevation myocardial infarction undergoing primary angioplasty.

Hypertension is a well-known risk factor for atherosclerosis. However, data on the impact of hypertension in patients with ST elevation myocardial infarction (STEMI) are inconsistent and mainly related to studies performed in the thrombolytic era, with very few data on patients undergoing primary angioplasty. The aim of the present study was to evaluate the impact of hypertension on distal embolization, myocardial perfusion, and mortality in patients with STEMI undergoing primary percutaneous coronary intervention.

Impact of multivessel disease on myocardial perfusion and survival among patients undergoing primary percutaneous coronary intervention with glycoprotein IIb/IIIa inhibitors.

Background: Although primary angioplasty achieves thrombolysis in myocardial infarction (TIMI) 3 flow in most patients with ST-elevation myocardial infarction, epicardial recanalization does not guarantee optimal perfusion in a large proportion of patients. The influence of multivessel disease on myocardial reperfusion and survival after primary angioplasty has not been extensively investigated.

Aim: To evaluate the impact of multivessel disease on myocardial perfusion and survival in a large cohort of patients with ST-elevation myocardial infarction treated with angioplasty and glycoprotein (GP) IIb/IIIa inhibitors.

Impact of time-to-treatment on myocardial perfusion after primary percutaneous coronary intervention with Gp IIb-IIIa inhibitors.

Background: Primary angioplasty has been shown to be superior to thrombolysis. However, previous reports have shown a negative impact of longer time-to-treatment on myocardial perfusion and survival even with mechanical reperfusion. However, these deleterious effects might potentially be overcome by an extensive use of glycoprotein (Gp) IIb-IIIa inhibitors.

Impact of advanced age on myocardial perfusion, distal embolization, and mortality patients with ST-segment elevation myocardial infarction treated by primary angioplasty and glycoprotein IIb-IIIa inhibitors.

Despite mechanical reperfusion, the outcome is still unsatisfactory in elderly patients with ST-segment elevation myocardial infarction (STEMI). The vast majority of studies have been conducted without extensive use of glycoprotein (Gp) IIb-IIIa inhibitors, which have been associated with improved perfusion and survival. Thus the aim of the current study was to evaluate the impact of age on the angiographic and clinical outcome patients with STEMI undergoing primary angioplasty with Gp IIb-IIIa inhibitors.

Time-related impact of distal embolisation on myocardial perfusion and survival among patients undergoing primary angioplasty with glycoprotein IIb-IIIa inhibitors: insights from the EGYPT cooperation.

Aims: Considerable interest has been focused in recent years on the role of distal embolisation as a major determinant of impaired reperfusion after primary angioplasty for STEMI. The aim of the current study was to evaluate in a large cohort of STEMI patients undergoing primary angioplasty with glycoprotein (Gp) IIb-IIIa inhibitors, whether the impact of distal embolisation on myocardial perfusion and survival may depend on time-to-treatment.

Methods And Results: Our population is represented by 1,182 patients undergoing primary angioplasty for STEMI included in the EGYPT database.

Impact of preprocedural TIMI flow on myocardial perfusion, distal embolization and mortality in patients with ST-segment elevation myocardial infarction treated by primary angioplasty and glycoprotein IIb/IIIa inhibitors.

Background: Despite optimal epicardial recanalization, primary angioplasty for ST-elevation myocardial infarction (STEMI) is still associated with suboptimal reperfusion in a relatively large proportion of patients. The aim of the current study was to evaluate the impact of preprocedural TIMI flow on myocardial perfusion, distal embolization, and survival among STEMI patients undergoing primary angioplasty with glycoprotein (GP) IIb/IIIa inhibitors.

Methods: Our population is represented by a total of 1637 patients undergoing primary angioplasty for STEMI treated with GP IIb/IIIa inhibitors.

Gender-related differences in outcome after ST-segment elevation myocardial infarction treated by primary angioplasty and glycoprotein IIb-IIIa inhibitors: insights from the EGYPT cooperation.

Several studies have found that among patients with ST-elevation myocardial infarction (STEMI) treated by thrombolysis, female sex is associated with a worse outcome. The aim of this study was to investigate sex-related differences in clinical and angiographic findings in patients with STEMI treated with primary angioplasty and Gp IIb-IIIa inhibitors. Our population is represented by 1662 patients undergoing primary angioplasty included in the EGYPT database.

Impact of distal embolization on myocardial perfusion and survival among patients undergoing primary angioplasty with glycoprotein IIb-IIIa inhibitors: insights from the EGYPT cooperation.

Even though primary angioplasty is able to obtain TIMI 3 flow in the vast majority of STEMI patients, epicardial recanalization does not guarantee optimal myocardial perfusion, that remain suboptimal in a relatively large proportion of patients. Large interest has been focused in recent years on the role of distal embolization as major determinant of impaired reperfusion. The aim of the current study was to investigate in a large cohort of STEMI undergoing primary angioplasty with Gp IIb-IIIa inhibitors the impact of distal embolization on myocardial perfusion and survival.

Association between advanced Killip class at presentation and impaired myocardial perfusion among patients with ST-segment elevation myocardial infarction treated with primary angioplasty and adjunctive glycoprotein IIb-IIIa inhibitors.

Background: Although primary angioplasty has been shown to improve survival as compared with thrombolysis, the outcome is still unsatisfactory in subsets of patients such as those with signs of heart failure at presentation. In fact, although primary angioplasty is able to restore TIMI 3 flow in most patients, suboptimal myocardial reperfusion is observed in a relatively large proportion of patients. The aim of this study was to investigate among patients with ST-segment elevation myocardial infarction undergoing primary angioplasty the association between heart failure at presentation and myocardial perfusion and its implications in terms of survival.

Diabetes mellitus is associated with distal embolization, impaired myocardial perfusion, and higher mortality in patients with ST-segment elevation myocardial infarction treated with primary angioplasty and glycoprotein IIb-IIIa inhibitors.

Background: It has been shown that, among patients with ST-segment elevation myocardial infarction (STEMI), diabetes is associated with a significantly higher mortality. The aim of the current study was to investigate the impact of diabetes on myocardial perfusion and mortality among STEMI patients treated with primary angioplasty and glycoprotein IIb-IIIa inhibitors.

Methods: Our population is represented by a total of 1662 patients undergoing primary angioplasty for STEMI included in 11 randomized trials.

Benefits of pharmacological facilitation with glycoprotein IIb-IIIa inhibitors in diabetic patients undergoing primary angioplasty for STEMI. A subanalysis of the EGYPT cooperation.

The Early Glycoprotein IIb-IIIa inhibitors in Primary angioplasty (EGYPT) cooperation aimed at evaluating, by pooling individual patient's data of randomized trials, the benefits of pharmacological facilitation with Gp IIb-IIIa inhibitors among STEMI patients undergoing primary angioplasty. In the current study we analyze the benefits of early Gp IIb-IIIa inhibitors in diabetic patients. The literature was scanned by formal searches of electronic databases (MEDLINE, EMBASE) from January 1990 to October 2007.

Effectiveness of primary percutaneous coronary intervention for acute ST-elevation myocardial infarction from a 5-year single-center experience.

Primary percutaneous coronary intervention (PCI) is currently viewed as the preferred reperfusion strategy in patients with ST-elevation acute myocardial infarction (STEMI). This method was introduced in our hospital in 2000. From January 1, 2000, to December 31, 2004, a total of 2,393 consecutive patients with STEMI were admitted (27% transferred from 9 non-PCI hospitals and 31 prehospital emergency units/outpatient clinics).

Early versus periprocedural administration of abciximab for primary angioplasty: a pooled analysis of 6 studies.

Background: The 2004 ACC/AHA guidelines on ST-elevation myocardial infarction state that it is reasonable to start treatment with abciximab as early as possible before primary percutaneous coronary intervention (PCI). We investigated the potential benefit of early use of abciximab by pooling data from all the available studies.

Methods: Six prospective studies were identified that had allocated 260 patients to receive early abciximab (either prehospital or soon after the patient arrived in hospital) and 342 to receive late abciximab (at the time of PCI).

Plasminogen activator inhibitor-1, which is released from blood product transfusions, might be associated with (sub)acute thrombosis after coronary dilatation and stenting: a case report.

We present the case of a 71-year-old man who suffered bleeding complications after coronary dilatation and stenting, necessitating a substantial number of platelet and whole blood transfusions in the following days. Postmortem analysis of plasma samples obtained after the transfusions revealed unexpectedly elevated levels of plasminogen activator inhibitor-1 (PAI-1) antigen and activity associated with a nonmeasurable euglobulin clot lysis time, disclosing extreme hypofibrinolysis, which might facilitate coronary thrombosis. The patient died suddenly on day 6, very likely due to coronary thrombosis.
