"Therapeutic branch of medical science deals with the application of remedies to diseases. As per Zhongjie Sun, University of Florida molecular cardiology is a new and fast-growing area of cardiovascular medicine that aims to apply molecular biology techniques for the mechanistic investigation, diagnosis, prevention and treatment of cardiovascular disease. As an emerging discipline, it has changed conceptual thinking of cardiovascular development, disease etiology and pathophysiology. Although molecular cardiology is still at a very early stage, it has opened a promising avenue for understanding and controlling cardiovascular disease. With the rapid development and application of molecular biology techniques, scientists and clinicians are closer to curing heart diseases that were thought to be incurable 20 years ago. There clearly is a need for a more thorough understanding of the molecular mechanisms of cardiovascular diseases to promote the advancement of stem cell therapy and gene therapy for heart diseases. The present paper briefly reviews the state-of-the-art techniques in the following areas of molecular cardiology: gene analysis in the diseased heart; transgenic techniques in cardiac research; gene transfer and gene therapy for cardiovascular disease; and stem cell therapy for cardiovascular disease. A scholarly article is based on original research or findings. Scholarly article is generally written by a researcher or expert in the field who is affiliated with an educational institution such as college or a university. Scholarly writings include footnotes or bibliography as references for the study. It also includes graphs or charts as illustrations as opposed to glossy pictures. In addition, articles that appear in scholarly journals or book that is published by academic presses are subject to a peer-review process, which means that other experts or specialist in the field would evaluate the quality and originality of the research as precondition of publication. International Journal of Cardiovascular Research emerges as a best indexed journal with impact factor compared to other competitive journals focusing especially on topics related to therapeutic advances in cardiovascular diagnosis and other cardiology studies by bringing up the recent research to global scientific community through its publications. The papers submitted are undergone through perfect plagiarism checks, later peer reviewed by the expert group and published after through revisions. "
