In sports athletes with coronary artery disease, two degrees of risk are described: Mildely elevated risk: preserved remaining ventricular systolic function normal workout tolerance for age, demonstrated during home treadmill or cycle ergometer workout testing absence of exercise-induced ischemia or complex ventricular arrhythmias absence of hemodynamically significant stenosis in virtually any major coronary artery successful myocardial revascularization. Substantially improved risk: Impaired still left ventricular systolic function at rest Evidence of exercise-induced myocardial ischemia or complicated ventricular arrhythmias Hemodynamically significant stenosis of a major coronary artery .In each combined group, the %age of stage IA and stage IB lung cancers was highest among cancers which were diagnosed after a positive screening test . Fewer stage IV cancers were seen in the low-dosage CT group than in the radiography group at the second and third screening rounds . Low-dose CT screening determined a preponderance of adenocarcinomas, including bronchioloalveolar carcinomas. Although the usage of the word bronchioloalveolar carcinoma is certainly no recommended longer,23 while the NLST was ongoing, the term was utilized to denote in situ, invasive minimally, or invasive adenocarcinoma, lepidic predominant .
