Conservative versus invasive strategy in elderly patients with non-ST-elevation myocardial infarction: insights from the international POPular age registry
This registry assessed the impact of conservative and invasive strategies on major adverse clinical events (MACE) in elderly patients with non-ST-elevation myocardial infarction (NSTEMI). Patients aged ≥75 years with NSTEMI were prospectively registered from European centers and followed up for one year. Outcomes were compared between conservative and invasive groups in the overall population and a propensity score-matched (PSM) cohort. MACE included cardiovascular death, acute coronary syndrome, and stroke. The study included 1190 patients (median age 80 years, 43% female). CAG was performed in 67% (N = 798), with two-thirds undergoing revascularization. Conservatively treated patients had higher baseline risk. After propensity score matching, 319 patient pairs were successfully matched. MACE occurred more frequently in the conservative group (total population 20% vs. 12%, adjHR 0.53, 95% CI 0.37–0.77, p = 0.001), remaining significant in the PSM cohort (18% vs. 12%, adjHR 0.50, 95% CI 0.31–0.81, p = 0.004). In conclusion, an early invasive strategy was associated with benefits over conservative management in elderly patients with NSTEMI. Risk factors associated with ischemia and bleeding should guide strategy selection rather than solely relying on age
Long-term comparison of balloon angioplasty with provisional stenting versus routine stenting in patients with non-ST-elevation acute coronary syndrome
Background. In patients with unstable angina or non-ST-elevation acute coronary syndrome (NSTE-ACS) who are eligible for PCI, routine stenting is the recommended treatment strategy, based on the opinion of experts. Provisional stenting may provide a viable alternative by retaining the early benefits of stenting without its potential late hazards
Association of serial high sensitivity troponin T with onset of atrial fibrillation in ST elevation myocardial infarction patients undergoing primary percutaneous coronary intervention
Item does not contain fulltextAIMS: Previous reports claimed that high sensitivity troponin T (HsTnT) is not associated with atrial fibrillation (AF) in the setting of acute ST-elevation myocardial infarction (STEMI) and primary percutaneous coronary intervention. However, the association of serial HsTnT levels and new-onset AF is unknown. We therefore assessed the temporal association between HsTnT levels and post-infarction AF. METHODS AND RESULTS: 830 patients enrolled in On-TIME II were included. HsTnT was assessed at baseline, and 24h and 72h after admission for STEMI. New-onset AF episodes were divided into three subgroups: AF during the first 24h of admission, AF 24-72h after admission and AF >72h after admission. ROC analysis and binary logistic regression were performed. Mean age was 62+/-12 years and 76% were male. Seventy-three patients developed new-onset AF: 41 patients developed AF during the first 24h of admission, 14 patients developed AF 24-72h after admission and 18 patients developed AF >72h after admission. HsTnT at baseline was associated with new-onset AF (area under curve (AUC) 0.596, p=0.008), but not with AF during the first 24h of admission (AUC: 0.539, p=0.414). HsTnT after 24h (AUC 0.792, p=0.001) and after 72h (AUC: 0.884, p72h after admission. HsTnT after 24h and 72h were stronger predictors of AF compared with HsTnT at baseline. In regression analysis, age (odds ratio 1.056, p1 (odds ratio: 2.694, p=0.010) and HsTnT after 24h (odds ratio: 1.012, p=0.017) and after 72h (odds ratio: 1.035, p<0.001) showed the strongest association with post-infarction AF. CONCLUSION: Serial HsTnT plasma levels are associated with post-infarction, new-onset AF
Predictors and importance of prolonged hospital stay after primary PCI for ST elevation myocardial infarction
Item does not contain fulltextOBJECTIVE: Although most patients with ST-elevation myocardial infarction treated by primary percutaneous coronary intervention (PCI) have a good prognosis and can be discharged from hospital very soon, some patients must be admitted longer. We performed the current analysis to assess predictors and the prognostic significance of prolonged hospital stay. PATIENTS AND METHODS: In this prospective observational study, individual data from 2323 patients who survived at least 2 days after primary PCI in our hospital were recorded. Patients in the highest tertile of hospital stay were compared with the other patients. Both predictors and prognostic importance of prolonged hospital stay were evaluated. RESULTS: Mean admission duration was 6.7 days (standard deviation=6.6). A total of 797 patients had a hospital stay for more than 6 days (highest tertile). Patients with a longer hospital stay were older, more often female, had more often a history of previous myocardial infarction and signs of heart failure on admission, and had more frequently Thrombolysis in Myocardial Infarction flow 0 before PCI. In addition, a low left ventricular ejection fraction was independently associated with prolonged hospital stay [odds ratio: 2.06 (95% confidence interval: 1.54-2.76)], but with a comparable risk of 1-year mortality [odds ratio: 1.3 (95% confidence interval: 0.8-2.0)]. CONSLUSION: According to this study, a low left ventricular ejection fraction is associated with prolonged hospital stay in patients after primary PCI. Predictors of prolonged hospital stay are age, female sex, previous myocardial infarction, heart failure on admission, and Thrombolysis in Myocardial Infarction flow 0 before PCI
