Rehabilitation Practice and Science

This study investigated whether coronary artery disease patients with chronotropic incompetence (CI) can significantly improve their functional capacity after exercise training. Forty-two men (mean age: 55.3±9.3yr) underwent coronary revascularization and without beta-blockade participated in a threemonth outpatient exercise training program. Patients were separated into a CI group (n=18) and a non-CI group (n=24) based on whether they could reach 85% of the age-predicted peak heart rate (HR). Chronotropic incompetence was defined as failure to achieve 85% of the age-predicted maximal HR. Bicycle exercise workouts were conducted three times weekly. The exercise duration was 30 minutes per session included 5 minutes …
