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.
