Journal of Cardiology

Top Research Topics at Journal of Cardiology?

Journal of Cardiology was organized to reinforce research efforts on Internal medicine, Cardiology, Myocardial infarction, Heart failure and In patient. Topics like Coronary artery disease, Atrial fibrillation, Percutaneous coronary intervention, Diastole and Electrocardiography are tackled as part of the discussions on Internal medicine. Catheter ablation and Sinus rhythm are among the concentrations of Atrial fibrillation that garnered much attention in Journal of Cardiology.

The work tackled in the journal goes beyond the discipline of Percutaneous coronary intervention as it also encompasses Conventional PCI. Cardiology research discussed connects with the study of Surgery. The journal focused on Myocardial infarction research but expanded to cover Angioplasty.

Publication chance based on affiliation

The publication chance index shows the ratio of articles published by the best research institutions in the journal edition to all articles published within that journal. The best research institutions were selected based on the largest number of articles published during all editions of the journal.

The chart below presents the percentage ratio of articles from top institutions (based on their ranking of total papers).Top affiliations were grouped by their rank into the following tiers: top 1-10, top 11-20, top 21-50, and top 51+. Only articles with a recognized affiliation are considered.

During the most recent 2021 edition, 9.75% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 26.76% were posted by at least one author from the top 10 institutions publishing in the journal. Another 11.27% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 26.29% of all publications and 35.68% were from other institutions.

Returning Authors Index

A very common phenomenon observed among researchers publishing scientific articles is the intentional selection of journals they have already attended in the past. In particular, it is worth analyzing the case when the authors participate in the same journal from year to year.

The Returning Authors Index presented below illustrates the ratio of authors who participated in both a given as well as the previous edition of the journal in relation to all participants in a given year.

Returning Institution Index

The graph below shows the Returning Institution Index, illustrating the ratio of institutions that participated in both a given and the previous edition of the conference in relation to all affiliations present in a given year.

The experience to innovation index

Our experience to innovation index was created to show a cross-section of the experience level of authors publishing in a journal. The index includes the authors publishing at the last edition of a journal, grouped by total number of publications throughout their academic career (P) and the total number of citations of these publications ever received (C).

The group intervals were selected empirically to best show the diversity of the authors' experiences, their labels were selected as a convenience, not as judgment. The authors were divided into the following groups:

• Novice - P < 5 or C < 25 (the number of publications less than 5 or the number of citations less than 25),
• Competent - P < 10 or C < 100 (the number of publications less than 10 or the number of citations less than 100),
• Experienced - P < 25 or C < 625 (the number of publications less than 25 or the number of citations less than 625),
• Master - P < 50 or C < 2500 (the number of publications less than 50 or the number of citations less than 2500),
• Star - P ≥ 50 and C ≥ 2500 (both the number of publications greater than 50 and the number of citations greater than 2500).

The chart below illustrates experience levels of first authors in cases of publications with multiple authors.

A Brief Guide to Career Opportunities in Cardiology

For readers interested in deeper engagement with the study of cardiology, it's crucial to understand the academic and career roadmap into the field. Generally, aspiring cardiologists start by pursuing a Bachelor's degree in a relevant field such as Biology or Pre-Med. This is followed by a 4-year medical post-graduate program to become a certified doctor. After obtaining a license to practice general medicine, they then proceed to a specialized residency in internal medicine, followed by a fellowship in cardiology. Cardiologists can choose to delve into further sub-specialties like electrophysiology or interventional cardiology depending upon their interest and career aspirations. For readers interested in entering the nursing field with a specialization in cardiology, the steps are somewhat different. After completes an undergraduate nursing degree, they can then proceed into specialized training programmes that target cardiovascular care. For example, aspiring nurses in South Carolina should look at this guide: how to become a registered nurse in South Carolina. Regardless of the specific path chosen, a career in Cardiology provides a rewarding opportunity to contribute to the ongoing development of medical science and deliver valuable healthcare services. Those interested should stay updated with leading journals like the Journal of Cardiology, which can be an invaluable resource to gain latest insights about the field.
