    Objective: The right ventricle myocardial infarction (RVMI) is one of the leading reasons for right ventricle(RV) dysfunction. RVMI occurs in 20-50% of inferior infarctions. Echocardiography was applied to study RV involvement and proximal right coronary artery (RCA) occlusion in individuals with acute inferior MI. The objective of this study was to investigate if pulmonary annulus motion velocity (PAMVUT) levels in individuals with acute inferior myocardial infarction were linked to proximal RCA lesions.Method: The study comprised 50 people who had been diagnosed with acute inferior myocardial infarction and had culprit lesions in the right coronary artery. The RCA occlusion in Group A was proximal to the right ventricular branch, while the RCA occlusion in Group B was distant to the RV branch. The PAMVUT was tested, as well as other echocardiographic parameters.Results: In terms of metrics indicating right ventricular function, there were substantial disparities between the groups. A favorable association was established in the univariate correlation analysis between PAMVUT and RV TAPSE, with FAC, and with St.PAMVUT was identified as an independent predictor of proximal RCA occlusion in a multivariate logistic regression test. In the ROC analysis, PAMVUT<8,5 cm/s indicated proximal RCA occlusion with 85 percent sensitivity and 69 percent specificity (AUC=0.80, p<0.001).Conclusion: PAMVUT measurements were revealed to be an important predictor of proximal RCA occlusions in this investigation.

    Aim: To investigate the markers that may predict both atrial fibrillation (AF) and atherosclerosis in obese \rpatients.\rMethod: This study was conducted on 108 participants (54 women and 54 men) with a body mass index (i.e., \rBMI) of at least 30. In addition to the electrocardiogram (ECG) and transthoracic echocardiography (TTE) \rfindings, we also analyzed the findings of body composition by means of the bioelectric impedance analysis \rmethod using the Tanita MC 780 MA analyzer in all participants.\rResults: We found that the minimal area of the left atrium (LA) had a very strong (r = 0.978, p = 0.022) \rcorrelation with visceral adiposity and a weak positive correlation with waist circumference. Aortic stiffness \rhad a weak positive correlation with visceral adiposity ratio (p = 0.022) and fat mass (r = 0.323, p = 0.001). \rThe diameter of LA had weak positive correlations with visceral adiposity (p = 0.018), waist circumference (r \r= 0.336, p < 0.001), fat-free mass (r = 0.323, p = 0.001), muscle mass (r = 0.324, p = 0.001), liquid mass (r = \r0.323, p = 0.001) and metabolic age (r = 0.364, p < 0.001). Again, we found weak positive correlations of \repicardial fat tissue with visceral adiposity (r = 0.459, p = 0.018) and metabolic age (r = 0.350, p < 0.001).\rConclusions: In our study, it has been noted that obese patients may have different levels of risk for AF and \ratherosclerosis, and there may be a more risky subgroup in which the distribution of some anthropometric and \rbody tissue components differs.
