The effect of ginseng supplement on heart rate, systolic and diastolic blood pressure to resistance training in trained males
Ginseng Panax has been used for centuries in Chinese medicine as source of health and stamina. We want to examine the affect of ginseng supplement on heart rate, systolic; blood pressure and diastolic blood pressure in trained athletes at rest, during and after resistance; training.

Shock index for outcome and risk stratification in acute pulmonary embolism
Risk stratification of patients with acute pulmonary embolism (PE) is crucial in deciding appropriate therapy management. Shock index (SI) is rapidly available and a reliable parameter. We aimed to investigate SI for short term outcome in acute PE. (Source: Artery Research)

Loss of elastic fiber integrity compromises common carotid artery function: Implications for vascular aging
Competent elastic fibers endow central arteries with the compliance and resilience that are fundamental to their primary mechanical function in vertebrates. That is, by enabling elastic energy to be stored in the arterial wall during systole and then to be used to work on the blood during diastole, elastic fibers decrease ventricular workload and augment blood flow in pulsatile systems. Indeed, because elastic fibers are formed during development and stretched during somatic growth, their continual tendency to recoil contributes to the undulation of the stiffer collagen fibers, which facilitates further the overall complia...

Combination therapy in hypertension: From effect on arterial stiffness and central haemodynamics to cardiovascular benefits
Measures of arterial aging have the potential to improve risk prediction beyond traditional risk scores. Such biomarkers that fulfil most, or some of the strict criteria of a surrogate end-point are aortic stiffness (IIa level of recommendation in European Guidelines and Position Papers) and central haemodynamics (IIb level of recommendation). Early intervention towards improving aortic elastic properties acquires particular importance since evidence suggests that arterial stiffening may occur before the onset of hypertension.

Vascular adaptation to extreme conditions: The role of hypoxia
The study of vascular adaptation to extreme conditions, and in particular to hypoxia, represents a unique opportunity in cardiovascular physiology, with relevant translational implications. First, it has crucial clinical consequences for about 140 million people worldwide living at high altitude and chronically exposed to hypobaric hypoxia. Second, an increasing number of lowlanders are exposed to high altitude for recreational or working purposes, including aged, diseased individuals: in these cases, hypoxia could be a trigger for acute cardiovascular events.

Anatomic variations of the renal arteries from a local study population using 3D computed tomography angiography reconstruction images from a reference hospital in Cali, Colombia
With the advances in the new image techniques and 3D modeling, angiography computed tomography (A-CT) has became a very useful image for studying vessels. Renal artery (RA) variations are common, and have a clinical relevance in pre-operative planning. There are several descriptive studies made in high income countries, but there are not many in middle and low income countries. Our objective was to describe prevalence of RA variations in a study population in Cali, Colombia. (Source: Artery Research)

Arterial stiffness: From surrogate marker to therapeutic target
Carotid-femoral (aortic) pulse wave velocity (PWV) is the modern benchmark for the assessment of arterial stiffness. Current European hypertension guidelines acknowledge the good cardiovascular (CV) predictive value, reproducibility and cost-effectiveness of PWV. Aortic PWV is an asset to classical cardiovascular risk scores and can reclassify patients. Reference values for carotid-femoral PWV have been established. Together with standardisation of user procedures and patient conditions, these reference values are needed for an appropriate use of aortic stiffness in daily clinical practice.

The effects of antihypertensive drugs on arterial stiffness
Ageing and cardiovascular risk factors, particularly uncontrolled hypertension, adversely impact arterial stiffness and wave reflection leading to increased central systolic blood pressure. Carotid-femoral pulse wave velocity is the “gold standard” method for the assessment of aortic stiffness. Increased pulse wave velocity has been independently associated with adverse cardiovascular outcomes. Thus, current European hypertension guidelines acknowledge the reproducibility, predictive value, and cost-effectiveness of pulse wave velocity. (Source: Artery Research)

Repeatability measurements of second systolic shoulder of the radial waveform and peripheral augmentation index with the OMRON HEM-9000AI device in a sample of young Mexican subjects
The development of non-invasive technology to perform pulse wave analysis and accurately determine central blood pressure has facilitated the study of central blood pressure as a physiologic and biomarker parameter. Central systolic blood pressure (cSBP) has been shown to be significantly associated with adverse outcome such as mortality and associated with adverse outcome. One of the most commonly evaluated features of the arterial pressure waveforms is augmentation index (AIx). Nowadays, there are multiple devices that have been developed for calculate AIx at peripheral arteries. (Source: Artery Research)
