Although chronic obstructive pulmonary disease has been related to heart failure, the relationship between the restrictive spirometry pattern (forced vital capacity [FVC] < 80% predicted with preserved forced expiratory volume in 1 second [FEV1]/FVC ratio) and heart failure is poorly understood. ⋯ Both a restrictive pattern on spirometry and airflow obstruction identify African Americans with impaired lung health at risk for heart failure.

Individuals diagnosed with cystic fibrosis (CF) as adults represent a growing subpopulation of CF cases, but there are limited studies describing their characteristics and prognosis. ⋯ CF care providers can use this information to inform individuals who received a diagnosis of CF as adults about their prognosis and to guide the necessity of treatments, specifically with regard to those who are at high risk for a worse prognosis.
