Prevalence and associated factors of mortality after percutaneous coronary intervention for adult patients with ST-elevation myocardial infarction: A systematic review and meta-analysis. JOURNAL OF RESEARCH IN MEDICAL SCIENCES 2023; 28:17. [PMID: 37064794 PMCID: PMC10098139 DOI: 10.4103/jrms.jrms_781_21] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/06/2021] [Revised: 10/13/2022] [Accepted: 11/17/2022] [Indexed: 03/18/2023]
Abstract
Background There is a paucity of systematic reviews on the associated factors of mortality among ST-elevation myocardial infarction (STEMI) patients after percutaneous coronary intervention (PCI). This meta-analysis was designed to synthesize available evidence on the prevalence and associated factors of mortality after PCI for adult patients with STEMI. Materials and Methods Databases including the Cochrane Library, PubMed, Web of Science, Embase, Ovid, Scopus, ProQuest, MEDLINE, and CINAHL Complete were searched systematically to identify relevant articles published from January 2008 to March 2020 on factors affecting mortality after PCI in STEMI patients. Meta-analysis was conducted using Stata 12.0 software package. Results Our search yielded 91 cohort studies involving a total of 199, 339 participants. The pooled mortality rate for STEMI patients after PCI was 10%. After controlling for grouping criteria or follow-up time, the following 17 risk factors were significantly associated with mortality for STEMI patients after PCI: advanced age (odds ratio [OR] = 3.89), female (OR = 2.01), out-of-hospital cardiac arrest (OR = 5.55), cardiogenic shock (OR = 4.83), renal dysfunction (OR = 3.50), admission anemia (OR = 3.28), hyperuricemia (OR = 2.71), elevated blood glucose level (OR = 2.00), diabetes mellitus (OR = 1.8), chronic total occlusion (OR = 2.56), Q wave (OR = 2.18), without prodromal angina (OR = 2.12), delay in door-to-balloon time (OR = 1.72), delay in symptom onset-to-balloon time (OR = 1.43), anterior infarction (OR = 1.66), ST-segment resolution (OR = 1.40), and delay in symptom onset-to-door time (OR = 1.29). Conclusion The pooled prevalence of mortality after PCI for STEMI patients was 10%, and 17 risk factors were significantly associated with mortality for STEMI patients after PCI.

Prognostic value of initial QRS analysis in anterior STEMI: Correlation with left ventricular systolic dysfunction, serum biomarkers, and cardiac outcomes. Ann Noninvasive Electrocardiol 2021; 26:e12791. [PMID: 32845542 PMCID: PMC7816810 DOI: 10.1111/anec.12791] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/23/2020] [Revised: 06/19/2020] [Accepted: 06/27/2020] [Indexed: 01/25/2023] Open
Abstract
BACKGROUND The presence of pathologic Q waves on admission electrocardiogram (ECG) in patients with anterior ST-elevated myocardial infarction (STEMI) has been related to adverse cardiac outcomes. Our study evaluates the prognostic value of QRS complex and Q waves in patients with STEMI undergoing percutaneous coronary intervention. METHODS We prospectively analyzed the specific characteristics of QRS complex and pathologic Q waves on admission and on discharge ECG in 144 patients hospitalized for anterior STEMI. We correlated these findings with the development of left ventricular systolic dysfunction (LVSD), appearance of heart failure (HF) or death during follow-up, and levels of several biomarkers obtained 6 months after the index event. RESULTS Multivariate logistic regression analysis showed that QRS width (odds ratios [OR] 1.05, p = .001) on admission ECG and the sum of Q-wave depth (OR 1.06, p = .002) on discharge ECG were independent predictors of LVSD development. Moreover, QRS width on admission ECG was related to an increased risk of HF or death (OR 1.03, p = .026). Regarding biomarkers, QRS width on admission ECG revealed a statistically significant relationship with the levels of NT-pro-BNP at 6 months (0.29, p = .004); the sum of Q-wave depth (0.27, p = .012) and width (0.25, p = .021) on admission ECG was related to the higher levels of hs-cTnI; the sum of the voltages in precordial leads both on admission ECG (-0.26, p = .011) and discharge ECG (0.24, p = .046) was related to the lower levels of parathormone. CONCLUSIONS Assessment of QRS complex width and pathologic Q waves on admission and discharge ECGs aids in predicting long-term prognosis in patients with STEMI.

Regression of Q waves and clinical outcomes following primary PCI in anterior STEMI. J Electrocardiol 2019; 73:131-136. [PMID: 31668455 DOI: 10.1016/j.jelectrocard.2019.09.022] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2018] [Revised: 08/19/2019] [Accepted: 09/20/2019] [Indexed: 11/18/2022]
Abstract
BACKGROUND Pathological Q waves are correlated with infarct size, and Q-wave regression is associated with left ventricular ejection fraction improvement. There are limited data regarding the association of Q-wave regression and clinical outcomes. Our main objective was to assess the association of pathological Q wave evolution after reperfusion with clinical outcomes after anterior STEMI. METHODS Standard 12-lead electrocardiograms (ECGs) were recorded in 780 anterior STEMI patients treated with primary percutaneous coronary intervention (PCI) from the CIRCUS trial. ECGs were recorded before and 90 min following PCI, as well as at hospitalization discharge and 12 months of follow-up. The number of classic ECG criteria Q waves was scored for each ECG. Patients were classified in the Q wave regression group if they had regression of at least one Q wave between the post-PCI, the discharge and/or one year ECGs. Patients were classified in the Q wave persistent group if they had the same number or greater between the post-PCI, the discharge and/or 1 and one year ECGs. All-cause death and heart failure events were assessed for all patients at one year. RESULTS There were 323(43%) patients with persistent Q waves (PQ group), 378(49%) patients with Q wave regression (RQ group) and 60(8%) patients with non-Q wave MI (NQ group). Infarct size as measured by the peak creatine kinase was significantly greater in the PQ group compared to the RQ and NQ groups (4633 ± 2784 IU/l vs. 3814 ± 2595 IU/l vs. 1733 ± 1583 IU/l respectively, p < 0.0001). At one year, there were 22 deaths (7%) in the PQ-group, 15 (4%) in the RQ-group and none in the NQ-group (p = 0.04). There was a 4-fold increase in the risk of death or heart failure in the PQ compared to the NQ group (HR 4.7 [1.1; 19.3]; p = 0.03), but there was no significant difference between NQ and RQ groups (HR 3.3 [0.8; 13.8]; p = 0.09). CONCLUSION In a population of anterior STEMI patients, persistent Q waves defined according to the classic ECG criteria after reperfusion was associated with a 4-fold increase in the risk of heart failure or death compared to non-Q-wave MI, while Q-wave regression was associated with significantly lower risk of events.

Which admission electrocardiographic parameter is more powerful predictor of no-reflow in patients with acute anterior myocardial infarction who underwent primary percutaneous intervention? J Electrocardiol 2017; 51:203-209. [PMID: 29174098 DOI: 10.1016/j.jelectrocard.2017.10.008] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2017] [Indexed: 11/23/2022]
Abstract
BACKGROUND Acute transmural ischemia due to left anterior descending artery (LAD) occlusion changes precordial R and Q wave durations owing to depressed intramyocardial activation. We investigated the prognostic value of sum of precordial Q wave duration/sum of precordial R wave duration ratio (Q/R) in patients with first acute anterior myocardial infarction (AAMI) treated with primary percutaneous coronary intervention (PPCI). METHODS In this prospective analysis, we evaluated the no-reflow predictive value of Q/R on 403 patients with first AAMI. Patients were divided into two as no-reflow group (n=32) and control (n=371) group according to post-PPCI flow status. RESULTS The patients in the no-reflow group had significantly higher Q/R on admission electrocardiography (ECG) compared to patients in the control group (p<0.001). When admission ECG parameters were compared according to no-reflow prediction, Q/R was stronger than other well-accepted parameters. The best cut-off value of the Q/R to predict no-reflow was 1.08 with 76% sensitivity and 73% specificity (AUC: 0.78; 95% CI: 0.72-0.83; p<0.001). CONCLUSION In patients with first AAMI treated with PPCI, Q/R in admission ECG may have a role as an independent predictive marker of no-reflow.

Abstract
BACKGROUND We investigated the prognostic value of precordial total Q wave amplitude/precordial total R wave amplitude ratio (Q/R) in patients with first acute anterior MI treated with primary percutaneous coronary intervention (PPCI). METHODS We evaluated the in-hospital prognostic impact of Q/R on 354 patients with first acute anterior MI. Patients were stratified by tertiles of admission Q/R, clinical outcomes were compared between those groups. RESULTS In-hospital univariate analysis revealed notably higher rates of in-hospital death for patients in tertile 3, as compared to patients in tertile 1 (OR 9.7, 95% CI 2.8-33.5, p. CONCLUSION Q/R in admission ECG in patients with first acute anterior MI provide an independent prognostic marker of in-hospital outcomes.

Abstract
OBJECTIVE The aim of this study was to investigate the impact of admission systolic blood pressure (ASBP) and left ventricular (LV) mass on the postreperfusion LV recovery in patients with ST-segment elevation myocardial infarction (STEMI) and concomitant coronary multivessel disease (MVD). MATERIALS AND METHODS A retrospective analysis of 12-month postreperfusion LV recovery was performed in 104 patients after primary percutaneous coronary intervention (PPCI). Patients with elevated ASBP (>140mmHg) were assigned to the first group (n=58); with normal ASBP (<140mmHg), to the second group (n=46); with increased myocardial mass index (MMI) (>100g/m(2)), to the third group (n=70); and with normal MMI (<100g/m(2)), to the fourth group (n=34). Severity of MVD was evaluated by the Syntax score. The LV recovery was assessed by evolution of quantitative characteristics of electrocardiography (QRS score, ST score, ECG STEMI stage) and echocardiography (LV ejection fraction, volume and mass indices) registered before and after PPCI, at discharge, and after 1, 6, and 12 months. RESULTS There were no significant differences in the baseline QRS and ST scores, ECG STEMI stage, LVEF, MMI, and Syntax score comparing all the patients' groups. The serial ECG criteria showed only a very small impact of ASBP on postreperfusion LV recovery. Only ECG STEMI stage progression was slower in the patients with elevated ASBP. In patients with different MMI, the QRS and ST scores were higher and ECG STEMI stage was lower in patients with increased MMI. LVEF after 1 year was significantly lower in the third group as compared to the fourth group (42.58%±8.25% vs. 46.8%±7.13%, P=0.018). CONCLUSION Postreperfusion LV recovery was more related not to ASBP but to the increased LV mass assessed by echocardiography in patients with STEMI and MVD.

Abstract
OBJECTIVES Following reperfusion therapy, early T wave inversions (TWI) have been shown to be a marker of successful reperfusion. We aimed to evaluate the relationship of TWI on the presenting ECG with spontaneous reperfusion as assessed by coronary angiography in patients with ST elevation (STE) myocardial infarction (STEMI). METHODS Data of 146 consecutive patients presenting to the St. Luke's Episcopal Hospital Emergency Department with acute STEMI undergoing primary percutaneous coronary intervention (p-PCI) between January, 2007 and October, 2010 were retrospectively analyzed. Clinical data, ECG and angiographic data were reviewed. Patients were dichotomized based on T wave morphology on the presenting ECG into 2 groups - those with TWI and those with positive T waves (PTW). RESULTS Thirty-one patients (21.2%) had TWI, while 115 (78.8%) had PTW. Sixty-four (43.8%) patients had anterior STE and 75 (51.3%) had inferior STE. Anterior STE was more likely to have TWI than non-anterior (29.7% vs. 14.6; p=0.014). By angiography, infarct related artery (IRA) patency (TIMI 2-3 flow) was seen in 45 (30.8%). TWI was more likely to be associated with IRA patency compared to PTW (51.6% vs. 25.2%; p=0.008). In patients with anterior STEMI and TWI, patent IRA was seen more frequently compared to those with PTW (68.4% vs. 20%; p<0.001). There was no association of T wave morphology and TIMI flow in patients with non-anterior STEMI. Patients presenting with stuttering symptoms were more likely to have TWI (70.4% vs. 10.2%; p <0.001) suggesting recurrent episodes of reperfusion and ischemia. CONCLUSIONS In anterior STEMI patients, TWI on the presenting ECG is associated with spontaneous reperfusion. This relationship was not found among patients with non-anterior STEMI.

Abstract
BACKGROUND The relationships between Q waves that appear during the acute phase of ST-elevation myocardial infarction (STEMI), clinical characteristics, ST-segment resolution (STRes), and clopidogrel therapy in patients treated with fibrinolysis are not well described. HYPOTHESIS We hypothesized that Q waves would be associated with less successful reperfusion and increased cardiovascular events. METHODS In the CLARITY-TIMI 28 trial, 3491 STEMI patients treated with fibrinolysis were randomized to clopidogrel or placebo. Electrocardiograms were evaluated for STRes post-fibrinolysis and the presence of pathologic Q waves during the index hospitalization in 3322 patients. RESULTS Q waves were identified in 2045 patients (61.6%) prior to discharge and were associated with increased odds of congestive heart failure (CHF) (adjusted odds ratio [ORadj ]: 2.10, P = 0.002) or the composite of cardiovascular death/CHF at 30 days (ORadj : 2.08, P ≤ 0.001). Q waves were associated with lower odds of Thrombolysis in Myocardial Infarction [TIMI] flow grade 2 to 3 (ORadj : 0.78, P = 0.028), TIMI myocardial perfusion grade 3 (ORadj : 0.83, P = 0.029), and complete STRes at 90 minutes (ORadj : 0.80, P = 0.030). Patients with both a Q wave and incomplete STRes 90 minutes after fibrinolysis were at higher risk for cardiovascular death or CHF (11.1%) than patients with no Q wave and at least partial STRes (1.9%). Overall, clopidogrel tended to be equally or more effective in patients without Q waves compared to those with Q waves. CONCLUSIONS Among STEMI patients treated with fibrinolysis, evaluating for Q waves prior to discharge is a simple method of assessing for less successful reperfusion and an increased risk of adverse 30-day cardiovascular outcomes. The combination of Q waves and 90-minute STRes allows additional risk refinement.
