1. Introduction
Changes in arterial distensibility occur with aging and arterial stiffness increases. These biophysical signs are elevated in cardiovascular conditions such as diabetes and hypertension.1,2 Measurement of central aortic pressures has an important clinical value in the early diagnosis of cardiovascular risk. Central aortic pressures are often different from peripheral pressures and they have more diagnostic value than peripheral pressures because they are pathophysiologically more relevant.3 Recently a ‘Generalized Transfer Function’ (GTF) technique has been developed and widely used to measure the central aortic pressures non-invasively using peripheral pulse wave analysis. Different types of equipment are available on the market to measure arterial stiffness using pulse wave analysis non-invasively. There are some differences between the measured values from those different systems,4 yet non-invasive measurements provide important diagnostic and prognostic values. Studies show that non invasive assessment of pulse wave and arterial stiffness can be an independent predictor for cardiovascular mortality in healthy people.5,6 The SphygmoCor is one of the recently developed, computerized, portable and simple to use devices to assess pulse waveforms, and one of the common systems in use for measuring arterial stiffness.7 It uses an arterial applanation tonometer for recording pressure waveforms. The advantage of this technique is the ease of performing applanation tonometry at the artery sites. Arterial stiffness varies with age, sex and ethnicity.8,9 However, the non-invasive arterial stiffness measures are less frequently studied and reference values are not established for South Asian populations such as in India. Measurement of exercise capacity using metabolic analysers is a standard method to predict or diagnose cardiovascular disease. Exercise capacity is inversely related to arterial stiffness in healthy people as well as those with cardiovascular conditions.10,11 For example pulse wave velocity, one of the arterial stiffness variables derived from pulse wave analysis, has been shown to have an inverse correlation with exercise capacity in people with coronary artery disease.12 Ethnic differences in exercise capacity have been observed and well established.13 However, the ethnic differences in the relationship between exercise capacity and arterial stiffness have been studied infrequently, especially between Caucasians and South Asians. The changes in arterial distensibility immediately following exercise may have important clinical importance. However, these are scarcely reported using maximum oxygen uptake (VO2) and non-invasive carotid-radial pulse wave analysis. The current study was carried out to explore the hypothesized acute changes in arterial stiffness using applanation tonometry following sub-maximal exercise in Caucasians and South Asians. This study also aims to find the relationships between exercise capacity and arterial stiffness. We hypothesized that there would be significant changes in arterial stiffness immediately after sub-maximal exercise and there would be significant relationships between exercise capacity variables using metabolic analysis and arterial stiffness variables using pulse wave analysis. It was also expected that there would be a significant difference between Caucasians and South Asians in exercise capacity and changes in arterial stiffness following acute exercise.
