[Diagnosis of ischemic heart disease in patients with bronchial asthma caused by cytotoxic dust].

To reveal latent IHD, the authors performed stress testing (veloergometry and transesophageal cardiac electric stimulation) in 63 patients with chronic obstructive dust bronchitis (CODB) and CODB complicated with bronchial asthma varying in severity. Latent IHD was diagnosed in 8% of the patients. Higher tolerance of physical exertion was seen in all groups of the patients, except for those with severe bronchial asthma--who had lower and medium tolerance. Patients with positive veloergometry test performed medium and high level of exertion.
