Incidence and short-term prognosis of late sustained ventricular tachycardia after myocardial infarction: Results of the Gruppo Italiano per lo Studio della Sopravvivenza nell’Infarto Miocardico (GISSI-3) Data Base

Clinical Impact of Ventricular Tachycardia and/or Fibrillation During the Acute Phase of Acute Myocardial Infarction on In-Hospital and 5-Year Mortality Rates in the Percutaneous Coronary Intervention Era

“…Major bleeding was defined as intracranial hemorrhage, bleeding requiring associated with increased in-hospital death; however, the effect of VT/VF on long-term mortality rates remains unclear. 1- 7 Recently, PCI has become a widely used therapeutic approach for the treatment of AMI patients. 8- 10 As compared with fibrinolytic therapy, PCI has better clinical outcomes in terms of higher success rates of infarct vessel reperfusion and greater reduction of infarct area.…”

Predictors of Ventricular Fibrillation at Reperfusion in Patients With Acute ST-Elevation Myocardial Infarction Treated by Primary Percutaneous Coronary Intervention

“…Because of its relatively low incidence, the predictors and prognostic value of VF at reperfusion are usually analysed together with other VF episodes at any time of acute STEMI (2)(3)(4). Some studies divided VF on early and late (2,5), some of them dealt with prereperfusion (6), periprocedural (1) or postprocedural (7) VF. While experimental studies have been searching for specific underlying mechanisms of reperfusional arrhythmias on cellular level, clinical studies focused on VF at reperfusion for STEMI in unselected populations, to the best of our knowledge, are lacking.…”

Predictors of ventricular tachyarrhythmia in high-risk myocardial infarction patients treated with primary coronary intervention

“…15 In accordance, previous studies have shown that late VT, but not early VT carries an adverse prognosis. 4,16 In order to verify our findings, however, a larger patient cohort with longer follow-up is needed.…”

“…2,3 Studies performed before the era of percutaneous coronary intervention (PCI) demonstrated the clinical relevance of ventricular arrhythmias if occurring >48 hours after AMI. [4][5][6] Factors associated with the occurrence of ventricular activity in these patients were the presence of extensive myocardial damage, reduced LV function and formation of ventricular aneurysm. 6,7 Since myocardial ischaemia and necrosis due to coronary occlusion is the key element leading to ventricular arrhythmias, angio graphic characteristics of AMI patients are of particular interest.…”
