VASCULAR DISEASES IN THE 21st CENTURY How Technology Plays a Role
TOPIC OUTLINE Description of the Evolution of Technology Effects of Technology on the Risk Factors for Vascular Disease Discussion of the Risk factors on Vascular Disease
Evolution of Technology The mid-twentieth century defined technology as the activity by which man seeks to manipulate his environment The twentieth century has seen manipulations being made and lifestyles being constantly improved as technology advanced.
High Tech Era: Bane or Boon? With technology advancement,the life style of man kept on changing = became more and more easy and comfortable Technology earlier was meant to provide comfortable life to man but later science and technology merged into one The technological advancement in science has to a great extent reduced death due to communicable diseases and epidemics = increased life-span of human beings
High Tech Era : Bane or Boon? Technological advancements lead to more sedentary lifestyle
Sedentary Behavior • Human endeavors resulting in energy expenditure of no more than 1.5 times resting energy expenditure • Time spent sitting, reclining, or lying down during waking hours • Independently associated with • lower levels energy expenditure • increased risk of weight gain • increased risk of metabolic syndrome • Diabetes • heart disease Charles E. Matthews, et al. Amount of Time Spent in Sedentary Behaviors in the United States, 2003–2004. Am J Epidemiol 2008;167:875–881
Older adolescents (ages 16–19 years) spent nearly 60% of their time, or >8 hours/day in sedentary behaviors Charles E. Matthews, et al. Amount of Time Spent in Sedentary Behaviors in the United States, 2003–2004. Am J Epidemiol 2008;167:875–881
Sedentary lifestyle and antecedents of vascular disease in young adults A total of 135 otherwise healthy young men (n = 68) and women (n = 67) <40 years of age Stratified into three groups based on physical activity status: 1) sedentary (n = 73); 2) physically active (n = 24); and 3) endurance-trained (n = 38) McGavockJM, Anderson TJ, LewanczukRZ. Am J Hypertens. 2006 Jul;19(7):701-7.
Sedentary lifestyle and antecedents of vascular disease in young adults • Arterial compliance and flow-mediated dilation were determined by diastolic pulse contour wave analysis and echocardiographic imaging of the brachial artery respectively. • Insulin sensitivity was estimated from the homeostasis model for insulin resistance and the 13C-glucose breath test.
Sedentary lifestyle and antecedents of vascular disease in young adults RESULTS: Both conduit (16.4 +/- 0.5 v 19.5 +/- 0.7 mL/mmHg x 10; P < .01) and resistant (8.5 +/- 0.3 v 10.7 +/- 0.5 mL/mmHg x 100; P < .01) artery compliance were significantly lower in sedentary subjects than in physically active or endurance-trained subjects The HOMA(IR) was 2.5-fold higher in the sedentary group than in the endurance-trained group (P < .05).

Sedentary Behaviour and Vigorous Physical Activity on Segment-Specific Carotid Wall Thickness In a population without increased CHD risk, the proportion of time spent in sedentary activity is directly associated with increase in IMT in the CCA, independent of age, and established atherosclerotic risk factors In the longitudinal analysis, subjects with short periods of vigorous PA at baseline had a lower CCA IMT progression over the following 3 years when compared with those with light-to-moderate activity Michaela Koza`kova, et al.

Low Recreational Activity as a Risk Factor for PeripheralArterialDisease 1381 patients with PAD (ankle-brachial index <0.9) at the time of elective angiography or a history of revascularization of the lower extremities regardless of ABI Validated physical activity questionnaire to retrospectively measure lifetime recreational activity (LRA). PAD was present in 19% (n = 258) of all subjects. Wilsom, AM et al. Abstract. Low lifetime recreational activity is a risk factor for peripheral arterial disease.

Low Recreational Activity as a Risk Factor for PeripheralArterialDisease Subjects with no regular LRA had greater diastolic BP and more likely to be female. They had lower average ABI, and a higher proportion had PAD (25.6%) Multivariate analysis showed that age (P < .001), female gender (P < .001), systolic blood pressure (P = .014), fasting glucose (P < .001), serum triglycerides (P = .02), and cumulative pack years (P < .001) were independent negative predictors of ABI, and LRA was a positive predictor of ABI (P < .001) History of sedentary lifestyle independently increased the odds ratio for PAD (odds ratio, 0.46; 95% confidence interval, 1.01-2.10) Wilsom, AM et al.

Sedentary Hours and Slow Walking Speed Predicts Functional Decline in PAD 384 patients with an ABI <0.90 Slower walking speed outside the home was associated with faster annual decline in calf muscle density Greater hours sitting per day were associated with faster decline in 6-min walk (<4 h: -35.8 feet/year; 4 to <7 h: -41.1 feet/year; 8 to <11 h: -68.7 feet; ≥12 h: -78.0 feet; p = 0.008). Similar associations were observed for greater hours sitting per day and faster declines in fast-paced (p = 0.018) and usual-paced (p < 0.001) 4-m walking velocity McDermott, MM et al. Abstract. Greater sedentary hours and slower walking speed outside the home predict faster declines in functioning and adverse calf muscle changes in peripheral arterial disease.

Associations of occupation with intima-media thickness: The Multi-Ethnic Study of Atherosclerosis (MESA) Blue-collar workers had greater internal carotid artery (ICA)-IMT than managers/professionals after adjustments were made for traditional cardiovascular disease risk factors and SES, suggesting that blue-collar jobs carry additional risk. Occupational category was more strongly associated with ICA-IMT, whereas job control was more strongly associated with common carotid artery (CCA)-IMT. Low job control was associated with greater CCA-IMT, with the association being stronger for those in high-demand jobs than in low-demand jobs. Kaori Fujishiro, et al.

SUMMARY With the evolution of technology, previously identified risk factors are becoming more prevalent and their association with vascular disease are becoming more evident. Low level physical activity is associated with impaired vascular function, development and progression of vascular diseases Technology is helpful in identifying modifiable risk factors Prevention, control and treatment of peripheral vascular disease should be the key focus
