ReviewIncreased cardiovascular risk in patients with chronic obstructive pulmonary disease and the potential mechanisms linking the two conditions: a review.
Cardiovascular diseases, especially coronary artery disease (CAD), are the leading causes of death in patients with chronic obstructive pulmonary disease (COPD). There is a high prevalence of common risk factors in the COPD/CAD patient population including smoking, sedentary lifestyle and low socio-economic status. ⋯ Statins and inhaled corticosteroids have been investigated as potential therapeutic interventions in COPD that may lower cardiovascular risk. The goals of this review are to examine the evidence for increased cardiovascular risk in COPD patients, the possible mechanisms linking these two chronic conditions, to discuss possible predictors or markers of poor outcomes among patients diagnosed with both COPD and CAD, and the therapeutic options aimed at reducing cardiovascular risks associated with COPD.

The presence of pulmonary arterial hypertension (PAH) in pregnancy is rare and signifies a high-risk pregnancy. Although the majority of mothers have knowledge of their condition before pregnancy, approximately one-third of patients are diagnosed during pregnancy. Termination of pregnancy should be discussed, and is often advised; however, a significant proportion of patients will choose to proceed with the pregnancy despite increased maternal and fetal mortality. ⋯ The time of greatest maternal risk is in the first month after delivery. Transplantation of these patients in the nonpregnant state may be considered when those with idiopathic pulmonary hypertension have poor functional status despite optimal therapy and their projected 2-year survival is less than 50%. For patients with Eisenmenger syndrome, severe symptoms and an unacceptable quality of life may lead to transplantation.
