Summary
This study analyzed the geographical origin of vascular research papers published between 2003-2006. The USA and Western Europe dominated vascular literature contributions, including high-quality randomized controlled trials (RCTs).
Area of Science:
- Vascular Surgery
- Bibliometrics
- Scientific Publishing
Background:
- Understanding the geographical distribution of scientific publications is crucial for assessing global research contributions.
- Previous analyses have highlighted regional disparities in medical research output.
Purpose of the Study:
- To investigate the geographical origin of published vascular research.
- To identify leading countries contributing to vascular literature and randomized controlled trials (RCTs).
Main Methods:
- A comprehensive search of electronic editions of four major vascular journals and two general surgical journals was conducted.
- Data from 2003-2006 were analyzed, focusing on the country of origin for all published papers.
- The geographical distribution of randomized controlled trials (RCTs) was specifically examined as an indicator of high-quality research.
Main Results:
- A total of 3422 papers from vascular journals and 144 vascular papers from general surgical journals were analyzed.
- The United States and Western European countries were found to be the largest contributors to the vascular literature.
- Out of 115 RCTs in vascular journals and 19 RCTs in general surgical journals, a significant proportion originated from these leading regions.
Conclusions:
- The USA and Western Europe are the primary sources of global vascular research publications.
- This dominance is consistent across both specialized vascular journals and general surgical literature, including high-impact randomized controlled trials.

01:20Overview of the Vascular System
The vascular system comprises an extensive network of arteries, capillaries, and veins. The vascular system can be broadly divided into the blood and lymphatic systems. Typically, blood vessels can be categorized into three histological regions: tunica intima, tunica media, and tunica adventitia. The tunica intima consists of a single layer of endothelial cells attached to the basal lamina. Underlying the basal lamina is a connective tissue layer and an elastic lamina that gives stability and...
02:03Anatomy of the Circulatory System
The human circulatory system consists of blood, blood vessels that carry blood away from the heart, around the body, and back to the heart, and the heart itself, which acts as a central pump. The systemic circuit supplies blood to the whole body, the coronary circuit supplies blood to the heart, and the pulmonary circuit supplies blood flow between the heart and lungs.
01:29Blood Flow
Blood is pumped by the heart into the aorta, the largest artery in the body, and then into increasingly smaller arteries, arterioles, and capillaries. The velocity of blood flow decreases with increased cross-sectional blood vessel area. As blood returns to the heart through venules and veins, its velocity increases. The movement of blood is encouraged by smooth muscle in the vessel walls, the movement of skeletal muscle surrounding the vessels, and one-way valves that prevent backflow.
01:20Vascular Resistance
Vascular resistance is a critical concept in understanding blood flow dynamics in the circulatory system. It refers to the resistance that blood encounters as it flows through the blood vessels. This resistance is a key factor in determining blood pressure and cardiac workload.
The primary determinants of vascular resistance are vessel diameter, blood viscosity, and vessel length. Among these, vessel diameter plays the most significant role due to the fourth power relationship described by...

01:24Regulation of Angiogenesis and Blood Supply
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl hydroxylase and factor...
01:27Anatomy of the Heart
The human heart is made up of three layers of tissue that are surrounded by the pericardium, a membrane that protects and confines the heart. The outermost layer, closest to the pericardium, is the epicardium. The pericardial cavity separates the pericardium from the epicardium. Beneath the epicardium is the myocardium, the middle layer, and the endocardium, the innermost layer. There are four chambers of the heart: the right atrium, the right ventricle, the left atrium, and the left ventricle.
