ABSTRACT

Nowadays, anesthesiologists are coping with larger numbers of high-risk respiratory

patients as a consequence of prolonged life expectancy, increasing prevalence of chronic

obstructive pulmonary disease (COPD) and greater needs for invasive diagnostic

procedures and surgical interventions (1). The prevalence of COPD is even higher among

some surgical candidates comparedwith age-matched population groups (e.g., 10-12% in

cardiac surgery and 40% in thoracic surgery vs. 5-10% in the general population) (1-3).

Since common risk factors (i.e., smoking, advanced age and sedentarity) are sharedbyboth

respiratory and cardiovascular diseases, a large proportion of COPD patients present

with hypertension (34%), occlusive or aneurysmal arterial disease (12%), cardiac

insufficiency (5%), arrhythmiac (4%), conduction blockade (10%), and/or ischemic heart

disease (11%) (4,5).
