“…Clinical outcomes such as heart failure (HF) and repeat revascularization have also been consistently related to the presence of Q waves on presentation, regardless of infarct location, adequacy of ST resolution, or early presentation (Kumar et al., 2009). Recent publications have focused on the presence of Q waves or Q/R wave relation on admission ECG (Hayiroglu, Uzun, Keskin, Borklu, Tekkesin, et al, 2018); to date, however, the characteristics of these pathologic Q waves have not been subjected to analysis. Serum biomarkers such as N‐terminal pro‐b‐type natriuretic peptide (NT‐pro‐BNP) and high‐sensitivity cardiac troponin I (hs‐cTnI) have also been found to be predictors of cardiac outcomes after MI (Radosavljevic‐Radovanovic et al., 2016) (Jansen et al., 2019).…”

“…There are some other predictors of post -PCI EF in ant MI patients. Hayıroğlu and colleagues assessed the prognostic value of precordial total Q wave amplitude to precordial total R wave amplitude ratio (Q/R) on 354 patients with first acute anterior MI treated with primary PCI, which indicated that Q/R is an independent prognostic factor for in-hospital mortality, cardiogenic shock and MACE [15]. Syntax score II (SSII) connects clinical variables with coronary anatomy.…”

Background To evaluate the predictive value of the index of microcirculatory resistance (IMR) for long-term cardiac systolic function after primary percutaneous coronary intervention (pPCI) in patients with acute anterior wall ST-segment elevation myocardial infarction (STEMI). Methods A total of 53 acute anterior wall STEMI patients were included and followed up within 1-year. IMR was measured to evaluate the immediate intraoperative reperfusion. IMR > 40 U was defined as the high IMR group and ≤ 40 U was defined as the low IMR group. Left ventricular ejection fraction (LVEF) was measured by echocardiography at 24 h, 1 month, 3 months, and 1 year after PCI to analyze the correlation between IMR and cardiac systolic function. Heart failure was estimated according to classification within one year. Results The ratio of TMPG (TIMI myocardial perfusion grade) 3 (85.7% vs. 52%, p = 0.015) and STR (ST-segment resolution) > 70% (82.1% vs. 48%, p = 0.019) were significantly higher in the low IMR group. The LVEF in the low IMR group was significantly higher than that in the high IMR group at 3 months (43.06 ± 2.63% vs. 40.20 ± 2.67%, p < 0.001) and 1 year (44.16 ± 2.40% vs. 40.13 ± 3.48%, p < 0.001). IMR was negatively correlated with LVEF at 3 months (r = − 0.1014, p = 0.0040) and 1 year (r = − 0.1754, p < 0.0001). Conclusions The IMR showed significant negative correlation with the LVEF value after primary PCI. The high IMR is a strong predictor of heart failure within 1 year after anterior myocardial infarction.

“…Hayiroglu et al 20 explored the effects of sex, body surface area, and target vessel size on clinical outcomes after angioplasty in their study. They found smaller target vessel size was associated with increased risk of restenosis and repeat revascularization; however, it did not appear to be a predictor for downstream mortality.…”

Predictors of left ventricle ejection fraction and early in-hospital mortality in patients with ST-segment elevation myocardial infarction: Single-center data from a tertiary referral university hospital in Istanbul

Background: Little is known about the management and mortality rates of ST-segment elevation myocardial infarction patients in developing countries. In this study, to expose independent predictors of early (24 h) in-hospital mortality and ejection fraction, we report our experience with 362 ST-segment elevation myocardial infarction patients admitted to the Istanbul Medical Faculty, Istanbul University, a tertiary referral university hospital, and treated with primary percutaneous intervention. Methods: This is a retrospective study that enrolled all patients (362) admitted with ST-segment elevation myocardial infarction to Department of Cardiology, Istanbul Medical Faculty, Istanbul University, between January 2015 and December 2016. The clinical characteristics of patients were collected retrospectively from medical chart review. Collected data were analyzed using IBM SPSS Statistics (version 21). Results: In the forward stepwise logistic regression analysis, target vessel diameter ( p = 0.001), systolic blood pressure ( p < 0.001), and troponin T levels ( p = 0.007) were independent predictors for early in-hospital mortality, while target vessel diameter ( p = 0.03), troponin T level ( p < 0.001), heart rate ( p = 0.001), and chest pain ( p = 0.001) duration were the independent predictors for ejection fraction of 50% and above. Conclusion: Our study is one of the few studies to investigate the predictors of early in-hospital mortality among patients hospitalized with ST-segment elevation myocardial infarction in a tertiary referral university hospital in a developing country. The identified predictors for mortality (including left ventricle ejection fraction and troponin T levels), left ventricle ejection fraction (including troponin T level, chest pain duration), and heart rate are consistent with what has been described in large registries in the United States and Europe.
