Kazemi E, Mansoursamaei A, Bijan M, Hosseinzadeh A, Sheibani H. The prognostic effect of ST-elevation in lead aVR on coronary artery disease, and outcome in acute coronary syndrome patients: a systematic review and meta-analysis. Eur J Med Res 2022; 27:302. [PMID: 36539835 PMCID: PMC9769006 DOI: 10.1186/s40001-022-00931-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2022] [Accepted: 12/03/2022] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Rapid diagnosis of coronary artery disease has an important role in saving patients. The aim of this study is to evaluate if aVR lead ST-elevation (STE) can predict LM/3VD, left main (LM) disease, and three-vessel disease (3VD), outcome in acute coronary syndrome (ACS) patients. METHODS In this systematic review and meta-analysis, 45 qualified studies were entered. Scopus, Pub med, Google scholar, Web of science, Cochrane library were searched on 12 November 2021. RESULTS This systematic review includes 52,175 participants. In patients with STE, the total odds ratios for LM, 3VD, and LM/3VD were 5.48 (95% CI 3.88, 7.76), 2.21 (95% CI 1.78, 3.27), and 6.21 (95% CI 3.49, 11,6), respectively. STE in lead aVR was linked with in-hospital death (OR = 2.99, CI 1.90, 4.72) and 90-day mortality (OR = 3.09, CI 2.17, 4.39), despite the fact that it could not predict 30-day mortality (OR = 1.11, CI 0.95, 1.31). The STE > 1 mm subgroup had the highest sensitivity for LM (0.9, 95% CI 0.82, 0.98), whereas the STE > 0.5 mm (0.76, 95% CI 0.61, 0.90) subgroup had the highest sensitivity for LM/3VD. The appropriate cut-off point with highest specificity for LM/3VD and LM was STE > 1.5 mm (0.80, 95% CI 0.75, 0.85) and STE > 0.5 mm, respectively (0.75, 95% CI 0.67, 0.84, I2 = 97%). CONCLUSION The odds of LM and LM/3VD were higher than 3VD in ACS patients with STE in lead aVR. Also, STE > 0.5 mm was the best cut-off point to screen LM/3VD, whereas for LM diagnosis, STE > 1 mm had the highest sensitivity. Furthermore, LM/3VD had a higher overall specificity than LM.

Abstract
BACKGROUND The aim of this study was to predict significant coronary artery disease (CAD) in patients undergoing coronary angiography. METHODS In this cross-sectional study, data of 384 patients who underwent angiography during 2015-2017 were reviewed. Electrocardiograms (ECGs) were evaluated in terms of having positive T wave in lead V1 (TV1) described as T wave with amplitude of more than 0.15 mV and angiography records were assessed for presence of significant CAD defined as presence of ≥ 70% internal diameter stenosis in at least one major epicardial coronary artery or more than 50% stenosis in left main artery (LMA). RESULTS Out of 384 patients who participated in this study with mean age of 63.6 ± 10.2 years (40-89 years), 71.6% showed positive TV1 and significant CAD simultaneously and left anterior descending artery (LAD) and left circumflex artery (LCX) lesions were more frequently reported in coronary angiography. Based on chi-square test, the prevalence of significant CAD was obviously more in those with positive TV1 as compared to those without this finding [odds ratio (OR) = 2.74, 95% confidence interval (CI): 1.80-4.19, P < 0.001]. Mann-Whitney test showed significant difference in number of coronary arteries involved in CAD between presence of positive and negative T wave in lead V1 (P < 0.001). Great number of patients with significant CAD had remarkably higher T wave amplitude in lead V1 in comparison to lead V6 (OR = 6.22, 95% CI: 3.14-12.30, P < 0.001). CONCLUSION Positive TV1 and TV1 > TV6 pattern can be considered as a predictor for significant CAD in patients with otherwise normal ECG.

Abstract
Background: Lead aVR provides prognostic information in various settings for patients with cardiovascular diseases. The present study aimed to investigate the prognostic value of a positive T wave in lead aVR (TaVR) for patients with acute pulmonary embolism (APE).Methods: We screened a total of 412 consecutive patients who were hospitalised with a diagnosis of APE between 2008 and 2018. We investigated electrocardiograms (ECGs) for the presence of a positive TaVR and classified other abnormal ECG findings. Additionally, clinical data, such as echocardiographic findings were recorded, and pulmonary embolism severity index (PESI) scores were calculated. The predictors of mortality at 30 days were investigated as the clinical outcome by logistic regression analysis.Results: In our study population, 54 patients (13.1%) died within 30 days. The prevalence of female gender, congestive heart failure, chronic obstructive pulmonary disease, and mean PESI scores were significantly higher in patients with a positive TaVR compared to those without it. Systolic blood pressure of patients with positive TaVR was significantly lower than that of patients without positive TaVR. In multivariate regression analysis; PESI scores (OR: 1.03; 95% CI: 1.01-1.04, p < .01), Right ventricular end-diastolic diameter (RVEDD) (OR: 1.07 95% CI: 1.01-1.13, p = .02), and a positive TaVR (OR: 4.41; 95% CI: 1.63-11.96, p < .01) were independently correlated with mortality.Conclusion: Positive TaVR, PESI scores, and RVEDD at hospital admission may have prognostic value in patients with APE. Positive T wave in lead aVR could be a useful marker in early risk stratification of pulmonary embolism.

Abstract
BACKGROUND A positive T wave in lead aVR (aVRT+) is an independent prognostic predictor of cardiovascular mortality in the general population as well as in cardiovascular disease. SUBJECTS AND METHODS We evaluated the prognostic impact of aVRT+ in an ECG recorded as close to hospital discharge as possible in acute coronary syndrome patients (n = 527). We divided the patients into three categories based on the findings in the admission ECG: ST elevation, global ischemia and other ST/T changes. RESULTS In the whole study population, and in all the three ECG subgroups, the 10-year all-cause mortality rate was higher in the aVRT+ group than in the aVRT- group. In Cox regression analysis, the age and gender adjusted hazard ratio (HR) for aVRT+ to predict all-cause mortality in the whole study population was 1.43 (95% confidence interval [CI] 1.12-1.83; p = 0.004). To predict cardiovascular mortality, the age and gender adjusted HR for aVRT+ was 1.54 (95% CI 1.14-2.07; p = 0.005) in the whole study population and 2.07 (95% CI 1.07-4.03; p = 0.032) in the category with other ST/T changes. CONCLUSION In ACS patients with or without ST elevation, but with ischemic ST/T changes in their presenting ECG, a positive or isoelectric T wave in lead aVR in an ECG recorded in the subacute in-hospital stage is associated with all-cause and cardiovascular mortality during long-term follow-up. Clinicians should pay attention to this simple ECG finding at hospital discharge.

The prognostic value of positive T wave in lead aVR: A novel marker of adverse cardiac outcomes in peripartum cardiomyopathy. Ann Noninvasive Electrocardiol 2019; 24:e12631. [PMID: 30653267 DOI: 10.1111/anec.12631] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/24/2018] [Revised: 10/28/2018] [Accepted: 11/03/2018] [Indexed: 12/30/2022] Open
Abstract
BACKGROUND Peripartum cardiomyopathy (PPCM) is an uncommon complication of pregnancy. Clinical courses of PPCM are markedly heterogeneous. Positive T waves in lead aVR (TaVR) are shown to be associated with adverse cardiac events in several cardiovascular diseases. We aimed to investigate the prevalence and prognostic role of positive TaVR in patients with PPCM. METHODS A total of 82 patients (mean age 29.1 ± 6.3 years) with the diagnosis of PPCM were enrolled. Presentation electrocardiogram (ECG) was investigated for presence of a positive TaVR. The median follow-up duration was 67.0 months. The primary endpoint was defined as composite cardiac events, including cardiac death, arrhythmic events, or persistent left ventricular systolic dysfunction. RESULTS Patients with positive T wave in lead aVR showed higher rates for persistent left ventricular systolic dysfunction, arrhythmic events, and cardiac death compared to patients without it. In multivariate logistic regression analysis, after adjusting for other confounding factors, the presence of positive TaVR was found to be as an independent and strong predictor of primary composite endpoint (odds ratio 6.21, 95% CI 1.45-26.51; p = 0.014). In Kaplan-Meier survival analysis, both primary and secondary endpoints occurred more frequently in the positive TaVR group. Using the cut-off level of 0.25 mV, T-wave amplitude in lead aVR predicted primary endpoint with a sensitivity of 100% and specificity of 100%. CONCLUSION Positive T wave in lead aVR, as a simple and feasible electrocardiographic marker, seems to be a novel predictor of adverse cardiovascular outcomes in patients with PPCM.

Abstract
BACKGROUND Lead aVR provides prognostic information in various settings in patients with ischemia. We aim to investigate the role of a positive T wave in lead aVR in non-ST segment myocardial infarction (NSTEMI). METHODS In a prospective cohort study, we included 400 patients with NSTEMI. Presentation electrocardiogram (ECG) was investigated for presence of a positive T wave as well as ST segment elevation (STE) in aVR and study variables were compared. Predictors of primary outcome defined as hospital major adverse cardiovascular events (MACE) and secondary outcome, defined as three-vessel coronary disease and/or left main coronary artery stenosis (3VD/LMCA) stenosis in angiography, were determined in multivariate logistic regression analysis. RESULTS Patients with a positive T wave in aVR were significantly older and were more likely to be female. Left ventricular ejection fraction was significantly lower in patients of positive T group. Positive T group was more likely to have 3VD/LMCA stenosis (58.3% vs. 19.8%, p < .001). The prevalence of a positive T wave in aVR was significantly higher in MACE group (54.9 % vs. 24.8%, p < .001). However, in multivariate analysis, it was not an independent predictor of MACE (OR: 1.083 95% CI: [0.496-2.365], p: .841). Though, it was independently associated with presence of 3VD/LMCA stenosis (OR: 3.747 95% CI: [2.058-6.822], p < .001). CONCLUSION Though positive T wave in lead aVR was more common in patients with MACE; it was not an independent predictor. Additionally, a positive T wave in aVR was an independent predictor of 3VD/LMCA stenosis in NSTEMI.
