“…In the research by Sonmez et al, both systolic and diastolic functions were affected after anterior ST-elevation MI. They also found a significant increase in RV Tei index, as an important factor affecting prognosis, after anterior MI (15).…”

A B S T R A C T Background:Unlike left ventricular function, less attention has been paid to Right Ventricular (RV) function after Myocardial Infarction (MI). Objectives: The current study aimed to compare RV function in patients with inferior and anterior MI. Patients and Methods: During the study period, 60 patients consecutively presented to the Emergency Department with chest pain were divided into two groups based on their electrocardiographic findings. Accordingly, 25 patients had inferior MI (IMI group) and 35 ones had anterior MI (AMI group). Echocardiography was performed 48 hours after starting the standard therapy. Conventional echocardiographic parameters and Tissue Doppler Imaging (TDI) measurements were acquired from the standard views. Student t-test and the chi-square test were respectively used for comparisons of the normally distributed continuous and categorical variables in the two groups. Besides, P < 0.05 was considered to be statistically significant. Results:The ratio of early diastolic velocity of the tricuspid flow to early diastolic velocity of the tricuspid annulus in the lateral side (E/E') was significantly higher in the AMI group compared to the IMI group (6.73 ± 1.64 vs. 5.68 ± 1.32, P = 0.01). In addition, abnormal E/E' ratio of the tricuspid valve was present in 27 (77%) and 14 (56%) patients in the anterior and inferior MI groups, respectively. Besides, the RV Tei index was significantly higher in the AMI group compared to the IMI group (0.65 ± 0.11 vs. 0.58 ± 0.13, P = 0.02). Overall, 28 patients (80%) with anterior infarction and 12 patients (48%) with inferior infarction had abnormal RV Tei index. However, no significant difference was found between the two groups regarding other variables. Conclusions: RV dysfunction commonly occurs after a first acute ST-elevation MI. However, RV functional changes are more pronounced in patients with anterior MI.

“…In a study, researchers utilized color-coded tissue Doppler imaging in patients with ASTEMI and demonstrated a decline in RV systolic function [ 26 ]. They, however, failed to define the time of echocardiography after ASTEMI, and they used an echocardiography modality that was not only dependent on the ultrasound beam angle but also associated with low spatial resolution, high noise, and interobserver variability [ 27 ].…”

Background Evidence suggests that changes in left ventricular systolic and diastolic functions may affect right atrial (RA) phasic functions. We aimed to evaluate RA phasic functions in the presence of anterior ST-elevation myocardial infarction (ASTEMI) as an acute event and to compare the findings with those in a control group. Methods We recruited 92 consecutive ASTEMI patients without accompanying significant stenosis in the proximal and middle parts of the right coronary artery and 31 control subjects, matched for age, sex, diabetes, and hypertension. RA phasic functions were evaluated concerning their longitudinal 2D speckle-tracking echocardiography-derived markers. The ASTEMI group was followed up for all-cause mortality or reinfarction. Results In the ASTEMI group, RA strain was reduced during the reservoir (33.2% ± 4.3% vs 30.5% ± 8.1%; P = 0.021) and conduit (16% [12–18%] vs 14% [9–17%]; P = 0.048) phases. The other longitudinal 2D speckle-tracking echocardiography-derived markers of RA phasic functions were not different between the 2 groups. RA strain and strain rate during the contraction phase were predictive of all-cause mortality or reinfarction (hazard ratio = 0.80; P = 0.024 and hazard ratio = 0.39; P = 0.026, respectively). Conclusions Based on 2D speckle-tracking echocardiography, in the ASTEMI group, compared with the control group, RA reservoir and conduit functions were reduced, while RA contraction function was preserved. RA contraction function was predictive of all-cause mortality or reinfarction during the follow-up period.

“…S/SR imaging is currently a very important echocardiographic modality for revealing subclinical myocardial damage. 51 In another study, Marmor et al 52 showed that in patients with anterior MI there was persistent regional and global impairment of LV function but only transient impairment of the RV, whereas inferior infarction was associated with severe, persistent regional and global impairment of the RV. In fact, in 22 patients who had anterior MI, the global RV ejection fraction was decreased reflecting a uniform depression of function without localized abnormalities and returned to normal by the tenth day.…”

“…However, this is not supported by anatomical and functional considerations. [40][41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56][57][58] In addition, RV involvement is an independent predictor of major cardiac adverse events. 43 In clinical practice low importance has been deserved to the RV during initial evaluation of the patients with acute settings of the anterior STEMI.…”

“…Simpson's RV ejection fraction was not significantly different between the 2 groups. 51 For the first time, Sonmez et al 51 evaluated RV regional function in patients who were successfully treated for their first anterior MI, using a strain and strain rate imaging tissue Doppler method, observing that both systolic and diastolic functions were affected after anterior STEMI. The patient group included 44 patients who had experienced their first anterior MI and had undergone successful percutaneous coronary intervention and 20 patients for the control group (selected by patients who had undergone coronary angiography in any centre and had a normal coronary artery or insignificant coronary stenosis <50%).…”
