• The white area in the upper lobe is cancer; the black areas are discoloration due to smoking.
  • Conclusions: Increased sympathetic nervous system activity, including thermoregulatory activity, might contribute to cachexia in smokers.
  • Conclusion: Compared to non-smokers, those who smoke have less parasympathetic activity and more sympathetic activity.
  • Most of the studies have been done to assess the sympathetic nerve activity among the smokers who were diabetics and hypertensive.
  • Conclusion: The unfavorable responses of sympathetic and arterial pressure to EC smoking are similar to those elicited by TC in healthy habitual smokers.
  • Conclusion: Sympathetic activity is increased and parasympathetic activity is decreased in smokers as compared to non-smokers.
  • However, muscle sympathetic nerve activity did not change significantly after smoking in middle-aged subjects (5 ± 8%, NS), despite the increased blood pressures...
  • In sustained handgrip test, rise in blood pressure is decreased in smokers as compared to non-smokers due to reduced sympathetic activity.
  • We have hypothesized that putative role of sympathetic ove-ractivity as a consequence of habitual smoking may affect P wave duration and PWD.
