The American Journal of Medicine (2009) 122, Prevalence of Comorbid Diagnoses and Symptoms Among a National Sample of Patients with COPD
Frequency distribution of comorbid conditions among patients with COPD. Barr, The American Journal of Medicine, 2009
The high prevalence of comorbidity in COPD is likely multifactorial and associated with age and multisystem impact of tobacco exposure COPD was less commonly treated than less symptomatic and less morbid conditions, such as hypertension and hypercholesterolemia, despite the increasing number of proven medications for the treatment of COPD Patients with COPD demonstrated better recall of their blood pressure and cholesterol than of their FEV1 This is not surprising in the context of the greater public education regarding hypertension and hypercholesterolemia Barr, The American Journal of Medicine, 2009
Prevention of exacerbations of chronic obstructive pulmonary diseases with tiotropium, a once-daily inhaled anticholinergic bronchodilator: a randomized trial.Co-morbilità Vascolari (compresa lipertensione) 64% Cardiache 38% Gastrointestinali 48% Metaboliche o nutrizionali 47% Muscolo scheletriche o connettivali 46% Genito-urinarie 27% Neurologiche 22% Niewoehner et al, Ann Intern Med 2005;143:
Role of co-morbidities in a cohort of patients with COPD undergoing pulmonary rehabilitation. Crisafulli E, et al.,Thorax 2008;63: % of the patients reported at least one chronic comorbidity added to COPD. Metabolic (systemic hypertension, diabetes and/or dyslipidaemia) and heart diseases (chronic heart failure and/or coronary heart disease) were the most frequently reported co-morbid combinations (61% and 24%, respectively)

. Soriano, CHEST population participants without CVD 52 population participants with CVD, 119 hospital patients with CAD
. Soriano, CHEST 2010
1.One of every three patients with CAD recruited from the hospital clinic, and one of every five patients with CVD in the general population, suffer AL compatible with COPD 2.The majority of them are not diagnosed, and, therefore, they remain mostly untreated. 3.These observations are clinically relevant because COPD is now considered a preventable and treatable disease. Soriano, CHEST 2010
For every 10% decrease in FEV 1, cardiovascular mortality increases by approximately 28% and non-fatal coronary event increases by approximately 20% in mild to moderate COPD Anthonisen et al, Am J Respir Crit Care Med 2002 Cardiovascular mortality in COPD
Emphysema severity is associated with arterial stiffness in patients with COPD Similar pathophysiological processes may be involved in both lung and arterial tissue Further studies are now required to identify the mechanism underlying this newly described association MacNee W et al, AJRCCM 2007; 176: ARTERIAL STIFFNESS IS INDEPENDENTLY ASSOCIATED WITH EMPHYSEMA SEVERITY IN PATIENTS WITH CHRONIC OBSTRUCTIVE PULMONARY DISEASE
The risk ratio of developing CHF in COPD patients is 4.5 (compared with age-matched controls without COPD after adjustments for cardiovascular risk factors ) (1) The rate-adjusted hospital prevalence of CHF is 3 times greater among patients discharged with a diagnosis of COPD compared with patients discharged without mention of COPD (2) (1) Curkendall SM, DeLuise C, Jones JK, et al.

INSULIN RESISTANCE AND INFLAMMATION - A FURTHER SYSTEMIC COMPLICATION OF COPD Bolton CE et al, COPD Jun ;4(2):121-6 This study demonstrates greater insulin resistance in non-hypoxaemic patients with COPD compared with healthy subjects, which was related to systemic inflammation. This relationship may indicate a contributory factor in the excess risk of cardiovascular disease and type II diabetes in COPD

REDUCTION OF MORBIDITY AND MORTALITY BY STATINS, ANGIOTENSIN-CONVERTING ENZYME INHIBITORS, AND ANGIOTENSIN RECEPTOR BLOCKERS IN COPD The combination of statins and either ACE inhibitors or ARBs is associated with a reduction in COPD hospitalization and total mortality not only in the high CV risk cohort but also in the low CV risk cohort Mancini JB, et al.

THE IMPACT OF CARDIOSELECTIVE BETA- BLOCKERS ON MORTALITY IN PATIENTS WITH COPD AND ATHEROSCLEROSIS -blockers are often withheld from patients with chronic obstructive pulmonary disease (COPD) because of fear of pulmonary worsening Beta1-blockers may reduce mortality in COPD patients undergoing vascular surgery (1) In some patients with COPD selective beta1-blockers are safe and may reduce mortality (2) 1) Van Gestel, Am J Respir Crit Care Med ) Salpeter S Cardioselective beta-blockers for chronic obstructive pulmonary disease.

Short PM et al., 2011 Kaplan-Meier estimate of probability of survival among patients with COPD by use of β blockers Β-blocker use was associated with a 22% reduction in mortality: hazard ratio 0.78 (95% confidence interval 0.67 to 0.92)
Conclusions β blockers may reduce mortality and COPD exacerbations when added to established inhaled stepwise therapy for COPD, independently of overt cardiovascular disease and cardiac drugs, and without adverse effects on pulmonary function. Short PM et al., 2011
Use of beta blockers and the risk of death in hospitalised patients with acute exacerbations of COPD In-hospital mortality was 5.2% In-hospital mortality was 5.2% Those receiving beta blockers (n = 142) were older and more frequently had cardiovascular disease than those who did not Those receiving beta blockers (n = 142) were older and more frequently had cardiovascular disease than those who did not Beta blocker use was associated with reduced mortality (OR = 0.39; 95% CI 0.14 to 0.99) Beta blocker use was associated with reduced mortality (OR = 0.39; 95% CI 0.14 to 0.99) The use of beta blockers by inpatients with exacerbations of COPD is well tolerated and may be associated with reduced mortality The use of beta blockers by inpatients with exacerbations of COPD is well tolerated and may be associated with reduced mortality Thorax Apr;63(4): Dransfield MT, Thorax Apr;63(4):301-5.

Caratteristiche della TEP in BPCO 1.Nearly 30% of all exacerbations of COPD do not have a clear etiology 2.COPD patients are at a high risk for PE due to a variety of factors including limited mobility, inflammation, and comorbidities 3.Overall, the prevalence of PE was 19.9% (95% confidence interval [CI], 6.7 to 33.0%; p 0.014). 4.In hospitalized patients, the prevalence was higher at 24.7% (95% CI, 17.9 to 31.4%; p 0.001) than those who were evaluated in the emergency department (3.3%)
1.One of four COPD patients who require hospitalization for an acute exacerbation may have PE. 2.A diagnosis of PE should be considered in patients with exacerbation severe enough to warrant hospitalization, especially in those with an intermediate-to-high pretest probability of PE.

La BPCO è uno dei fattori di rischio per tromboembolia polmonare La TEP deve essere considerata tra le cause di riacutizzazione di BPCO e la sua frequenza varia in funzione della casistica studiata e del setting clinico, potendo arrivare fino al 25% dei casi La diagnosi è resa difficile dallaspecificità dei sintomi e dalla possibile sovrapposizione con quelli di una riacutizzazione e la formulazione di uno score clinico di probabilità è utile sia per porre il sospetto sia per laccuratezza diagnostica. La performance clinica delle indagini diagnostiche, con eccezione per la scintigrafia polmonare perfusionale\ventilatoria, non è influenzata in modo significativo dalla presenza di BPCO. TEP in BPCO: messaggi chiave I
TEP in BPCO: messaggi chiave II Lo studio del circolo polmonare arterioso con tomografia computerizzata (angioTC polmonare) è lindagine di riferimento un eccessivo impiego di esami TC con mezzo di contrasto può essere evitato escludendo i soggetti con score di probabilità medio-basso associato a D-dimero negativo. La valutazione del rischio di morte (stratificazione del rischio con ricerca dei segni di disfunzione ventricolare destra ) è utile a fini prognostici e terapeutici
