The combined S velocity achieved from tricuspid annulus and pulmonary annulus with tissue Doppler imaging could predict the proximal right coronary artery occlusion in patients with inferior myocardial infarction

Aim: To investigate if combined S velocity (CSV) calculated from tricuspid annulus and pulmonary annulus with tissue Doppler imaging in individuals with acute inferior myocardial infarction were linked to proximal RCA lesions. Methods: The study comprised 48 patient 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 combined S velocity 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 CSV and tissue Doppler imaging derived tricuspid annulus systolic velocity (St), pulmonary annulus motion velocity evaluated by TDI (PAMVUT), RV tricuspid annular plane systolic excursion (TAPSE), and fractional area change (FAC). CSV was identified as an independent predictor of proximal RCA occlusion in a multivariate logistic regression test. In the ROC analysis, CSV<18.3 cm/s and PAMVUT<8.6 cm/s indicated proximal RCA occlusion with 83 percent sensitivity and 71 percent specificity (AUC=0.83, p<0.001), and 85 percent sensitivity and 71 percent specificity (AUC=0.81, p<0.001), respectively. Conclusion: CSV measurements were revealed to be an important predictor of proximal RCA occlusions in this investigation

Reverse type IV dual left anterior descending coronary artery accompanying with anomalous origin of circumflex artery from right coronary sinus

Dual left anterior descending (LAD) artery is an infrequent coronary anomaly classified into six types. Short LAD arising from left main coronary artery (LMCA) and long LAD sourcing from proximal right coronary artery comprise Type IV dual LAD. We reported anomalous origin of circumflex artery (Cx) with reverse Type IV LAD including short LAD arising from right coronary sinus and long LAD originated form LMCA

The usefulness of morphology‐voltage‐P wave duration ECG score for predicting early left atrial dysfunction in hypertensive patients

Objective Left atrial (LA) function is an important predictor of adverse cardiovascular outcomes in patients with hypertension (HT). Therefore, recognition of subtle LA dysfunction in the early stages of HT is essential for controlling modifiable variables. Several electrocardiographic and echocardiographic parameters have been studied to show early LA dysfunction. The goal of this study was to investigate the relationship between newly defined morphology‐voltage‐P wave duration electrocardiography (MVP ECG) score and early LA dysfunction in hypertensive patients. Materials and methods Eighty-nine hypertensive patients were included in this study. Based on speckle tracking echocardiography results, the patients were divided into two groups: 67 patients with normal LA function were included in Group 1, and 22 patients with abnormal LA function in Group 2. Results Age, diabetes mellitus history, duration of HT history, left ventricular mass index, E/Em, and MVP ECG score values were statistically significant between the two groups. Based on the results of the multivariate logistic regression test, duration of HT history, E/Em, and MVP ECG score were determined as independent predictive parameters for early LA dysfunction in hypertensive patients. Conclusion In conclusion, MVP ECG score assessment could be a novel approach to detect early LA dysfunction in hypertensive patients
