Q Wave

The development of pathological Q waves has long been correlated with worsened outcome in patients with ST elevation myocardial infarction (STEMI). In this study, we investigated long-term mortality of STEMI patients treated by primary percutaneous coronary intervention (PPCI) and compared predictive values of Q waves and of Selvester score for infarct volume estimation. Data of 283 consecutive STEMI patients (103 females) treated by PPCI were analysed. The presence of pathological Q wave was evaluated in pre-discharge electrocardiograms (ECGs) recorded ≥72 h after the chest pain onset (72 h Q). The Selvester score was evaluated in acute ECGs (acute Selvester score) and in the pre-discharge ECGs (72 h Selvester score). The results were related to total mortality and to clinical and laboratory variables. A 72 h Q presence and 72 h Selvester score ≥6 was observed in 184 (65.02%) and 143 (50.53%) patients, respectively. During a follow-up of 5.69 ± 0.66 years, 36 (12.7%) patients died. Multivariably, 72 h Selvester score ≥6 was a strong independent predictor of death, while a predictive value of the 72 h Q wave was absent. In high-risk subpopulations defined by clinical and laboratory variables, the differences in total mortality were highly significant (p < 0.01 for all subgroups) when stratified by 72 h Selvester score ≥6. On the contrary, the additional risk-prediction by 72 h Q presence was either absent or only borderline. In contemporarily treated STEMI patients, Selvester score is a strong independent predictor of long-term all-cause mortality. On the contrary, the prognostic value of Q-wave presence appears limited in contemporarily treated STEMI patients.

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 (&gt;50%). Results mrEF was present in 29.8% (n=2 427), whereas low ejection fraction (EF&lt;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&lt;40%, in terms of prior MI (14.5% in mrEF vs. 9.9% in preserved EF vs. 24.2% in low EF, p&lt;0.001), history of diabetes (26.5% vs. 21.2% vs. 30.0%, p&lt;0.001), presence of Killip 2–4 on admission (15.7% vs. 6.9% vs. 26.5%, p&lt;0.001) and median age (61 vs. 59 vs. 64 years, p&lt;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&lt;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&lt;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&lt;0.001). Conclusion Patients with mrEF after primary PCI for STEMI have a distinct baseline clinical risk profile, as compared with patients with reduced (&lt;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.

Long Term Mortality

Background: Acute treatment of ST-elevation myocardial infarction (STEMI) has focused on early reperfusion, prompt defibrillation, and appropriate mechanical support to mitigate short-term mortality. Long-term patterns of death in a contemporary population are not well described. Methods: We reviewed consecutive cases of STEMI treated with percutaneous coronary intervention (PCI) at our center between January 1, 2011, and December 31, 2016, and divided patients into two groups: uncomplicated STEMI (US) and complicated STEMI (CS). CS was defined by presence of cardiac arrest or cardiogenic shock, ascertained from first-medical-contact to device time for PCI. We assessed for differences in characteristics and short- and long-term mortality between the groups. Results: We identified 1,272 patients with STEMI; 214 of which were CS (16.8%). Those with CS were significantly more likely to have heart failure (22.9% vs 11.3%, p<0.001), kidney disease (38.2% vs. 21.0%, p<0.001), cerebrovascular disease (18.7% vs 11.0%, p=0.003), peripheral vascular disease (16.8% vs 7.9%, p<0.001), and left main or left anterior descending culprit vessel (51.9% vs. 40.3%, p<0.002). Total in-hospital mortality was 5.0% (63 patients), with 19.6% (42/214) and 2.0% (21/1058) of those with CS and US respectively (p<0.001). Among 1209 of patients that survived to hospital discharge, total long-term mortality was 10% (121 patients) of which 18.0% (31/172) had CS and 8.7% (90/1037) had US (p=0.001) over mean follow-up of 3.1±1.9 years. Of those, 52% and 50%, respectively, were from non-cardiovascular etiologies (Figure) including malignancy (13% vs. 22%), infection (22% vs. 19%), or other causes (17% vs. 9.0%). Conclusion: Despite advances in the in-hospital care of patients with STEMI, there remains a significant risk of long-term mortality for both patients with uncomplicated and complicated STEMI. A substantial proportion of overall STEMI mortality now occurs after hospital discharge predominantly due to non-cardiovascular causes. Systems of care to mitigate this long-term risk are needed.
