Abstract Background Previous studies have demonstrated the feasibility of primary percutaneous coronary intervention (PPCI) in carefully selected nonagenarians. Although current guidelines recommend immediate revascularization in patients with ST elevation myocardial infarction (STEMI) it remains unclear whether PPCI reduces mortality in nonagenarians. The objective of this study is to compare mortality in nonagenarians presenting via the PPCI pathway who undergo coronary intervention, versus those who are managed medically. Methods and results A total of 111 consecutive nonagenarians who presented to our tertiary center via the PPCI pathway between July 2013 and December 2018 with myocardial infarction were included. Clinical and angiographic details were collected alongside data on all-cause mortality. The final diagnosis was STEMI in 98 (88.3%) and NSTEMI in 13 (11.7%). PPCI was performed in 42 (37.8%), while 69 (62.2%) were medically managed. A significant number of the medically managed cohort had atrial fibrillation (23.2% vs 2.4% p = 0.003) and presented with a completed infarct (43.5% vs 4.8% p = 0.001). Other baseline and clinical variables were well matched in both groups. There was a trend towards increased 30-day mortality in the medically managed group (40.6% vs 23.8% p = 0.07). Kaplan Meier survival analysis demonstrated a significant difference in survival by 3 years (48.1% vs 21.7% p = 0.01). This was the case even when those with completed infarcts were excluded (44.3% vs 14.6%, p = 0.01). Conclusion In this series of selected nonagenarians presenting with acute myocardial infarction, those undergoing PPCI appeared to have a lower mortality compared to those managed medically.

Abstract Background Despite the implementation in the use of primary percutaneous coronary intervention (pPCI) and in secondary preventive measures, the risk of recurrence of myocardial infarction (MI) in patients who underwent ST-elevation myocardial infarction (STEMI) remains high. The prognostic role of old and emerging cardiovascular risk factors for MI recurrence, such as Lipoprotein(a) [Lp(a)] levels, in this very high-risk population is still not fully understood. Purpose To identify the baseline predictors of MI recurrence in a cohort of patients admitted for STEMI and treated with pPCI. Methods Single-center, observational, retrospective analysis of consecutive patients admitted for STEMI who underwent pPCI from February 2013 to April 2019 at our Insitution. Baseline demographic, clinical, echocardiographic and laboratory data were prospectively collected. Only patients with available Lp(a) values were included in the analysis. The study outcome was the recurrence of MI at three years follow-up. Univariable and multivariable Cox regression analysis was performed to identify the baseline variables correlated to the study outcome. Results The study population included 560 patients (mean age = 60.6±13.7 years; 79.5% males). Hypertension was observed in 351 patients (62.7%), diabetes in 134 (23.9%), dyslipidemia in 266 (47.5%), smoking status in 316 (56.4%), history of coronary artery disease (CAD) in 76 (13.6%), prior MI in 69 (12.3%), prior PCI in 62 (11.1%). Multivessel disease (MVD) was reported in 211 (37.7%) cases. The infarct-related artery was the left anterior descending in 310 patients (55.4%), the right coronary artery in 179 (32.0%), the left circumflex 60 (10.7%) and the left main in 11 (2.0%). Total cholesterol mean value was 187.7±48.8 mg/dl; LDL cholesterol was 112.2±41.3 mg/dl and Lp(a) was 26.5±27.2 mg/dl. At three-year follow-up, MI occurred in 58 (10.4%) patients. At multivariable analysis, Lp(a) (HR 1.015 95% CI: 1.008–1.022 p<0.001) and MVD (HR 1.994; 95% CI 1.179–3.372 p=0.010) emerged as the only two independent predictors of MI recurrence up to three years. The Kaplan-Meier analysis showed a significantly lower survival free from MI in patients with Lp(a) ≥50 mg/dl as compared to the subgroups with levels ≥30 and <50 mg/dL, or <30 mg/dL (Log-Rank=0.001). Also, MVD was able to identify patients with significantly lower survival free from MI for up to three years (Log-Rank=0.004). The Kaplan-Meier analysis combining these two parameters identified patients with both MVD and Lp(a) ≥50 mg/dl as the highest risk cohort for MI recurrence up to three years (MI incidence rate=22.2%; Log-Rank=0.002). Conclusions Among patients with STEMI who underwent pPCI, high Lp(a) level and MVD predict the recurrence of MI at long-term follow-up. Funding Acknowledgement Type of funding source: None

This article reviews optimum therapies for the management of ST-elevation myocardial infarction (STEMI) with primary percutaneous coronary intervention (PCI). Optimum anti-thrombotic therapy includes aspirin, bivalirudin and the new anti-platelet agents prasugrel or ticagrelor. Stent thrombosis (ST) has been a major concern but can be reduced by achieving optimal stent deployment, use of prasugrel or ticagrelor, selective use of drug-eluting stents (DES) and use of new generation DES. Large thrombus burden is often associated poor outcomes. Patients with moderate to large thrombus should be managed with aspiration thrombectomy and patients with giant thrombus should be treated with glycoprotein IIb/IIIa inhibitors and may require rheolytic thrombectomy. The great majority of STEMI patients presenting at non-PCI hospitals can best be managed with transfer for primary PCI even with substantial delays. A small group of patients who present very early, who are at high clinical risk and have long delays to PCI, may best be treated with a pharmaco-invasive strategy.

Abstract Background Previous studies associated midrange ejection fraction (mrEF) with impaired prognosis in patients with ST-elevation myocardial infarction (STEMI). Purpose Our aim was to assess clinical profile and short- and long-term mortality of patients with mrEF after STEMI treated with primary percutaneous coronary intervention (PCI). Methods This analysis included 8148 patients admitted for primary PCI during 2009–2019, from a high-volume tertiary center, for whom echocardiographic parameters obtained during index hospitalization were available. Midrange EF was defined as 40–49%. Adjusted Cox regression models were used to assess 30-day and 5-year mortality hazard of mrEF, with the reference category being preserved EF (>50%). Results mrEF was present in 29.8% (n=2 427), whereas low ejection fraction (EF<40%) was documented in 24.7% of patients (n=2 016). mrEF was associated with a higher baseline risk as compared with preserved EF patients, but lower when compared with EF<40%, in terms of prior MI (14.5% in mrEF vs. 9.9% in preserved EF vs. 24.2% in low EF, p<0.001), history of diabetes (26.5% vs. 21.2% vs. 30.0%, p<0.001), presence of Killip 2–4 on admission (15.7% vs. 6.9% vs. 26.5%, p<0.001) and median age (61 vs. 59 vs. 64 years, p<0.001). At 30 days, mortality was comparable in mrEF vs. preserved EF group, while it was significantly higher in the low EF group (2.7% vs. 1.6% vs. 9.4%, respectively, p<0.001). At 5 years, mrEF patients had higher crude mortality rate as compared with preserved EF, but lower in comparison with low EF (25.1% vs. 17.0% vs. 48.7%, p<0.001) (Figure). After adjusting for the observed baseline differences mrEF was independently associated with increased mortality at 5 years (HR 1.283, 95% CI: 1.093–1.505, p=0.002), but not at 30 days (HR 1.444, 95% CI: 0.961–2.171, p<0.001). Conclusion Patients with mrEF after primary PCI for STEMI have a distinct baseline clinical risk profile, as compared with patients with reduced (<40%) and preserved (≥50%) EF. Importantly, mrEF did not have a significant impact on short-term mortality following STEMI, but it did independently predict the risk of 5-year mortality.
