Key result
Compromised right ventricular longitudinal strain in patients with acute myocardial infarction was associated with a higher rate of major adverse cardiovascular events over 12 months (P=0.014).
Why the study?
The relationship between right ventricular function assessed by strain imaging and clinical variables and prognosis in acute myocardial infarction patients was not well defined.
Does right ventricular longitudinal strain (RVLS) assessment predict major adverse cardiovascular events (MACE) in patients with acute myocardial infarction?

p-value: p=0.014
Impaired right ventricular longitudinal strain assessed by speckle-tracking echocardiography is associated with a higher rate of major adverse cardiovascular events at 12 months in patients with acute myocardial infarction.
Impaired RV strain linked to worse LVEF and higher MACE in AMI; hypothesis-generating for strain-based risk stratification.
A BSTRACT Objective: This study sought to determine the relationship between right ventricular (RV) function and clinical variables and prognosis in individuals with acute myocardial infarction (AMI) utilizing strain imaging. Materials and Methods: A prospective observational research involving 150 patients who had been admitted with AMI was carried out. Utilizing two-dimensional speckle-tracking strain imaging, RV function was assessed. Age, sex, risk factors, and comorbidities were recorded as clinical parameters. A 12-month follow-up was conducted to assess major adverse cardiovascular events (MACE). Results: 65% of the study’s participants were men, with a mean age of 58.2 years. When compared to a healthy control group, individuals with AMI had significantly lower RV longitudinal strain (RVLS) ( P 0.001). RVLS and left ventricular ejection fraction had a statistically significant connection (r = 0.642, P 0.001). Patients with compromised RVLS had a greater rate of MACE over the follow-up period compared to those with maintained RV function ( P = 0.014). Conclusion: In conclusion, strain imaging offers useful information for evaluating RV function in patients with AMI. Reduced left ventricular performance and a higher likelihood of unfavorable clinical outcomes are linked to impaired RVLS. Utilizing strain imaging to detect RV dysfunction early can help direct treatment plans and enhance patient outcomes.
