A bibliometric analysis on the progress of myocardial bridge from 1980 to 2022

Abstract

IntroductionAlthough the vast majority of patients with a myocardial bridge (MB) are asymptomatic, the anomaly was found to be associated with stable or unstable angina, vasospastic angina, acute coronary syndrome, and even malignant arrhythmias and sudden cardiac death in some cases.MethodsBy retrieving the relevant literature on MB from 1 January 1980 to 31 July 2022 from the Web of Science Core Collection (WoSCC) database, we used the bibliometric tools, including CiteSpace, VOS viewer, and alluvial generator, to visualize the scientific achievements on MB.ResultsA total of 630 articles were included. The number of published articles was in a fluctuating growth trend. These publications came from 37 contries, led by the USA and China. The leading country on MB was the United States, the leading position among institutions was Stanford University, and the most productive researcher on MB was Jennifer A. Tremmel. After analysis, the most common keywords were myocardial bridge, mortality, coronary angiography, descending coronary artery, and sudden death.ConclusionOur findings can aid researchers in understanding the current state of MB research and in choosing fresh lines of inquiry for forthcoming investigations. Prevalence and prognosis, mechanism atherosclerosis, hemodynamic significance, and molecular autops will likely become the focus of future research. In addition, more studies and cooperations are still needed worldwide.

A Morphological Study of Myocardial Bridges in the Fetal Heart

“…Few studies justified embryonic development (13,14), while others pointed to the postnatal development of MBs (15). Another theory proposed that, despite the congenital origin of the MBs, their effect is exhibited only during adulthood (23,24). The mammalian hearts were found to have subepicardial mesenchymal cells.…”

“…Multiple studies have reported inconclusive impact of MBs (2, 5, 16,17,22,23), cardiac rhythm abnormalities like depression of QTc and monomorphic ventricular tachycardia were reported in children with hypertrophic cardiomyopathy with MBs (11). Direct compression of the coronary artery or the alteration of the distribution of atheroma by the MBs were the reasons for the strong association between MBs and coronary heart disease in young as well as old adults (33).…”

“…Despite being extensively reported in adults with developmental origin ( 16) and a debatable clinical significance (23), more research on the morphology of MBs in fetal hearts is needed. So, the present study was undertaken to observe the prevalence and morphology of MBs in fetal hearts toward aiming for early fetal coronary evaluation.…”

Ponte Miocárdica: fisiopatologia, diagnóstico e condutas terapêuticas

“…Normalmente, a PM tem sua ocorrência na artéria coronária descendente anterior, com profundidade entre 1mm a 10mm e comprimento aproximado de 10mm a 30mm. A porção íntima do segmento tunelizado se apresenta mais fina do que o segmento proximal, além de conter predominantemente células musculares lisas do subtipo contrátil (CHEN L, et al, 2023;ZHANG M, et al, 2023).…”

Trends and hotspots in familial hypercholesterolemia: A bibliometric systematic review from 2002 to 2022

“…With regard to the current status of research and the trajectory of specific research areas, there are many studies that use bibliometrics and knowledge mapping. [65][66][67][68] CiteSpace and the alluvial generator, which were used in this study, are the 2 of the most bibliometric tools. Our analysis strategy is similar to those employed in previous research.…”
